1 Overview of the Stormwater Management Program Plan
1.1 Introduction
This Stonnwater Management Program Plan (SMPP) was developed by the United City of
Yorkville based off a SMPP template created by the Lake County Stonnwater Management
Commission. The purpose of the SMPP is to meet the minimum standards required by the United
States Environmental Protection Agency (USEPA) under the National Pollutant Discharge
Elimination System ( NPDES) Phase II program. Federal regulations through the USEPA require
that all Municipal Separate Stone Sewer Systems (MS4s), partially or fully in urbanized areas based
on the 2000 census, obtain stormwater permits for their discharges into receiving waters.
The SMPP describes the procedures and practices that can be implemented by the City toward the
goal of reducing the discharge of pollutants within stormwater runoff in order to comply with
Federal standards. The SMPP is applicable to all properties within city limits. Compliance with the
plan is intended to protect water quality and contribute to the following amenities:
• cleaner lakes and streams,
• improved recreational opportunities and tourism,
• flood damage reduction,
• better aesthetics and wildlife habitat, and
• a safer and healthier environment for the citizens.
1.2 State & Federal Regulations
Federal environmental regulations based on the 1972 Clean Water Act (CWA) require that MS4s,
construction sites and industrial activities control polluted stormwater runoff from entering
receiving bodies of water (including navigable streams and lakes). The NPDES permit process
regulates the discharge from these sources based on amendments to CWA in 1987 and the
subsequent 1990 and 1999 regulations by the U.S. Environmental Protection Agency (USEPA). In
Illinois, the USEPA has delegated administration of the Federal NDPES program to the Illinois
Environmental Protection Agency (IEPA). On December 20, 1999 the IEPA issued a general
NPDES Phase II permit for all MS4s. Under the General ILR 40 Permit each MS4 was required to
submit a Notice of Intent (NOI) declaring compliance with the conditions of the permit by March
10, 2003. The original NOI describes the proposed activities and best management practices that
occurred over the original 5 -year period toward the ultimate goal of developing a compliant SMPP. '
At the end of the 5` year (March 1, 2008) the components of the SMPP were required to be
implemented; per the ILR40 permit. The IEPA reissued the ILR 40 permit on April 1, 2009. The
reissued permit is included in Appendix 5.10.
Additionally, under the General ILR10 permit also administered IEPA, all construction projects that
disturb greater than 1 acre of total land area are required to obtain an NPDES permit from IEPA
prior to the start of construction. Municipalities covered by the General ILR40 permit are
automatically covered under ILR10 30 days after the IEPA receives the NOI from the municipality.
1
i
1.3 Organization of SMPP
The SMPP identifies best management practices to be implemented in six different categories.
These categories are:
• Public Education and Outreach
• Public Participation /Involvement
• Construction Site Runoff Control
• Post - Construction Runoff Control
• Illicit Discharge Detection and Elimination
• Pollution Prevention/Good Housekeeping
Chapter 1: Overview of the Stormwater Management Program Plan - discusses the format of the
SMPP document and the regulations associated with NPDES II through state and federal agencies.
Chapter 2: Program Management - discusses the logistics of the plan. This includes the
organization, implementation and responsible parties necessary to achieve overall compliance with
the SMPP and NPDES Permit. It also identifies how the United City of Yorkville coordinates with
other governmental agencies and discusses the legal authority that the MS4s have to implement the
plan components.
Chapter 3: The Program - addresses stormwater pollutant control measures implemented by the
United City of Yorkville per the six minimum control categories established by the USEPA.
Chapter 4: Monitoring, Program Evaluation and Reporting - describes the monitoring, evaluation
and reporting procedures associated with the program. The SMPP is a guide created to protect
United City of Yorkville receiving waters from pollution and resultant degradation. This chapter
assists in identifying best management practices and processes that may require modifications in the
future to help the document become an effective tool.
Chapter 5: Appendices — including forms, references, and exhibits.
1.4 Watersheds and Receiving Waters
The United City of Yorkville is primarily located within the Fox River watershed, with southern
areas tributary to the Illinois River. There are several receiving waters tributary to the Fox and
Illinois Rivers which are located within the Village. These streams include Blackberry Creek, Rob
Roy Creek, and Aux Sable Creek. Ponds, intermittent streams, and other on- stream bodies of water
are also considered part of the receiving water system.
Watershed. The land area that contributes stormwater to one of the two major rivers
draining Kendall County.
2
I
Sub - Watershed: The land area that contributes stonnwater to one of the receiving waters
tributary to a major river.
Receiving Water: A natural or man -made system into which stormwater or treated
wastewater is discharged, including the Fox River, Illinois River, and their tributaries.
The major Watersheds and receiving waters are presented on Figure 1 Map of Major Sub - watershed
and Receiving Waters.
Fox River Watershed
The Fox River originates about 15 miles northwest of Milwaukee The river enters the
northeast corner of Kendall County at Montgomery. About 165 square miles of Kendall County
drain to the Fox River.
Major tributaries to the Fox River in Kendall County include Blackberry Creek, Rob Roy Creek,
Big Rock Creek, Little Rock Creek, Morgan Creek, Hollenback Creek, and Roods Creek. Only
Blackberry Creek, Rob Roy Creek, and Hollenback Creek are located within the current city limits.
The watersheds of the creeks within the city are primarily agricultural, although significant
development activity has occurred in the Blackberry Creek and Rob Roy Creek watersheds since
2000.
The Fox River watershed includes all or portions of the communities of Aurora, Millbrook,
Millington, Montgomery, Newark, Oswego, Plano, Sandwich, and Yorkville.
Illinois River Watershed
The Illinois River originates at the confluence of the Des Plaines and Kankakee Rivers in Grundy
County, about 10 miles southwest of Joliet, Illinois. About 155 square miles of Kendall County
drain to the Illinois River.
The Illinois River does not run directly through Kendall County, but reaches into the county via
Aux Sable Creek and Valley Run Creek. Only the Middle Branch of the Aux Sable Creek is located
within the current city limits.
The Middle Branch Aux Sable Creek is primarily agricultural, although some development activity
has occurred since 2000.
The Illinois River watershed includes all or portions of the communities of Joliet, Lisbon, Minooka
Plattville, Plainfield, and Yorkville.

2 Program Management
This Chapter describes the organizational structures of the United City of Yorkville and
the Illinois EPA. It further discusses the roles and responsibilities of the involved parties.
a
2.1 Implementation of this SMPP
The SMPP includes tasks that are required to meet the permit conditions under the
NPDES I1 program and how to perform these tasks. These forms should be printed
annually and the progress of all tasks tracked. At the end of-the yearly reporting period
(March 1 — February 28/29) the fornis should be filed in a binder to document SMPP
related activities to IEPA in the case of an audit. It is anticipated that implementation of
this SMPP constitutes compliance with the program. The SMPP will be posted on the
United City of Yorkville's website.
2.2 Departmental Responsibilities
The City Council is the policy and budget setting authority for United City of Yorkville.
The Engineering, Community Development, and Public Works Departments work
together to implement this SMPP. The City Engineer has primary responsibility for
managing the overall program. The city will also work with Kendall County and adjacent
municipalities regarding stormwater issues. j
The Community Development Department is designated as the primary entity responsible
for performing the duties related to Public Education and Outreach and Public
Participation and Involvement. Much of this work will be achieved through coordination
with the Green Committee. The Engineering Department is designated as the primary
entity responsible for performing the duties related to Construction Site Runoff Control,
Post - Construction Runoff Control, and Illicit Discharge Detection and Elimination
activities. The Building Department will assist as necessary by performing certain duties
during the construction of private developments. The Public Works Department is
designated as the primary entity responsible for performing the duties related to Pollution
Prevention and Good Housekeeping.
Measurable goals are established to document the efforts performed by the various city
departments and ultimately the effectiveness of the SMPP. Those departments
responsible for implementation of the SMPP shall perform, record, and forward monthly
report memos to the City Engineer regarding their individual areas of responsibility. The
report memos shall be prepared and forwarded during the first week of the following
month. The City Engineer shall use these reports in preparing the annual report to the
Illinois EPA.
i
5
2.3 Coordination with the IEPA
The United City of Yorkville is required to complete annual reports which describe the
status of compliance with the ILR40 permit. The annual report will be posted on the
City's website and submitted to the IEPA by the first day of June each year. Annual
reporting to IEPA should include information regarding SMPP goals that are in
compliance as well as those goals that need further work or modification.
Records regarding the completion and progress of the SMPP commitments will be I
documented on task sheets and updated throughout the year. The completed task sheets
should be located in a binder with necessary supporting documentation. The binder will
be available for inspection by both IEPA and the general public.

3 The Program
This Stormwater Management Program Plan includes six components, each of which is
necessary to reduce /eliminate stornwater pollution in receiving water bodies. These are:
• Public Education and Outreach
• Public Participation and Involvement
• Construction Site Runoff Control
• Post - Construction Runoff Control
• Illicit Discharge Detection and Elimination
• Pollution Prevention and Good Housekeeping
i
3.1 Public Education and Outreach
t
The United City of Yorkville established the Green Committee in October 2007. The
purpose of the Green Committee is to provide research, advice, and make
recommendations to the City Council on environmental issues facing the community. The
Green Committee promulgates infonnation related to recycling, conservation design, soil
conservation, rain gardens, open space /watershed protection, water conservation,
landscape maintenance, etc. through environmental fairs, a quarterly newsletter, pamphlet
distribution, and the city website.
The annual NPDES permit report shall be placed on a City Council agenda once each
year for discussion. j
11A Measurable Goals
• Place Stormwater Management Program Plan on the city's website.
• Maintain an information center at City Hall, which will include informational
items regarding stormwater- related issues.
• Have at least one item related to stormwater or recycling issues published in each
city newsletter.
3.2 Public Participation and Involvement
The Yorkville Green Committee is volunteer- based, and encourages citizen participation
and involvement for stormwater- related issues on both individual and community levels.
The committee publishes and distributes pamphlets informing homeowners on such
issues as re- landscaping their own property to encourage infiltration or cleansing of
stormwater, and pesticide/herbicide use. The Community Development Department shall
also work with homeowner associations regarding proper maintenance of private open
space.
7
Citizen calls related to the Stormwater Management Program Plan shall be documented
and directed to the appropriate department for follow -up.
3.2A Measurable Goals
• Maintain meeting minutes of the Green Committee.
• Document the number and type of calls received from the public regarding
potential illicit discharges.
• Sponsor an annual environmental fair, and document the number and type of
exhibitors and public attendance.
3.3 Construction Site Runoff Control
The City adopted Ordinance No.2003 -19 (Appendix 5.1) to regulate soil erosion and
sediment control practices for construction activities that disturb more than 10,000 SF of
soil. This ordinance requires the following:
• Requires the developer /contractor to follow Illinois EPA requirements regarding
NPDES permitting for construction activities.
• Issuance of a Site Development Pen regulating earthwork and erosion/sediment
control.
• Contractor requirements for periodic inspections during construction.
• Surety bonding to ensure that stabilization work is completed according to plan. j
r
The City passed Resolution No. 2004 -39 (Appendix 5.2) to establish the Standard
Specifications for Improvements. This resolution creates standards regarding the various
aspects of construction for public and quasi - public infrastructure, including responsible
construction activities. Regarding stormwater management, this resolution requires:
• Sizing requirements for stormwater collection and detention facilities.
• A soil erosion and sediment control plan.
• The ability to require stormwater best management practices in the design of the
stormwater collection and storage systems. j
i
The City passed Ordinance No. 2008 -01 (Appendix 5.3) to provide Wetland Protection
Regulations for Water Quality and Stormwater Management Benefits. This ordinance creates
requirements for the evaluation and protection of non jurisdictional wetlands within city limits
that may be affected by new development.
3.3A Complaints
Site design comments are handled on a case by case basis. Any complaints received during the
review, construction, or build -out of a private development shall be directed to the City
Engineer and documented. Construction and build -out related calls are typically addressed by
performing a site inspection.
8
i
3.3B Violation Notification Procedures
Investigation of complaints should be performed within one business day of receipt of the
complaint. In general the compliance due date should be within 5- working days.
However, if the city determines that the violation is or will result in significant
environmental, health or safety hazards a 24 -hour compliance requirement should be set.
For such time - critical violations, the developer should also be advised to complete a
Notice of Incidence report with the IEPA for all sites that were required to submit a
Notice of Intent to the IEPA.
Step 1 can be initiated by observation of a violation during a routine inspection, or in
response to a complaint.
Step 1: Violation Is Observed
• The inspector completes the NPDES/Erosion Control Inspection Report
(Appendix 5.11).
• Photographs of the violation(s) should be taken and saved.
• The development project manager /property owner (a.k.a. construction site
contact) shall be informed of the violation.
• A copy of the NPDESIErosion Control Inspection Report is provided to the
contractor and the developer. The NPDES /Erosion Control Inspection Report
indicates the deficiencies and a maximum time frame for action. I
• At the end of the indicated time frame the City shall perform a follow -up site
inspection.
Step 2: 1 St Follow -Up Site Inspection
The construction site contact shall be notified of the anticipated inspection time. The site
shall be inspected including all items previously documented on the previous
NPDES/Erosion Control Inspection Report. The inspector will determine if the
remedial measures have all been satisfactorily addressed, substantially completed, or if
significant non - compliance remains.
• If the remedial measures have been satisfactorily addressed then the
NPDES/Erosion Control Inspection Report is filled out indicating compliance
and provided to the contractor and developer.
• If the inspector determines that the remedial measures have been substantially
completed, but not entirely resolved, the inspector shall follow Step 1 above.
• If the inspector determines that the remedial measures have not been substantially
completed, the inspector shall follow Step 3 discussed below. Photographs of the
violations should be taken and saved.
Step 3: 1" Notice of Violation
9
I
l i
A formal Notice of Violation (Appendix 5.12) letter will be sent to the contractor and
developer. A copy of the Notice of Violation shall also be provided to the Yorkville
Building Department. The letter will include the following information:
• Description of the violations (including ordinance provisions)
• Maximum time frame for resolution (typically 5 working days),
Step 4: 2 "d Follow -Up Site Inspection
The inspector will determine if the remedial measures have all been satisfactorily
addressed, substantially completed, or if significant non - compliance remains.
• If the remedial measures have been satisfactorily addressed then the
NPDES/Erosion Control Inspection Report shall be filled out indicating
compliance and provided to the contractor and developer.
• If the inspector determines that the remedial measures have been substantially
completed, but not entirely resolved, the inspector shall follow Step 1 above. j
• If the inspector determines that the remedial measures have not been substantially j
completed, the inspector shall follow Step 5 discussed below. Photographs of the
violations should be taken.
Step 5: 2 "d Notice of Violation
• Depending on the severity of the outstanding violations the inspector may arrange
for the Building Department to issue a Red Tag and a Conditional Stop Work
Order upon completion of the inspection. The Stop Work Order allows for the
resolution of the violation but no other on -site improvements. Building and /or
Occupancy Permits will not be issued and surety /letter of credit reductions will
not be considered until the violation is resolved. A formal Notice of Violation
letter will be sent, via certified mail, to the contractor and developer. A copy of
the Notice of Violation shall also be provided to the Yorkville Building
Department.
Step 6: 3r Follow -Up Site Inspection
The inspector will determine if the remedial measures have all been satisfactorily
addressed, substantially completed, or if significant non - compliance remains.
• If the remedial measures have been satisfactorily addressed then the
NPDESIErosion Control Inspection Report is filled out indicating compliance
and provided to the contractor and developer.
• If the inspector determines that the remedial measures have been substantially
completed, but not entirely resolved, the inspector shall follow Step 1 above.
• If the inspector determines that the remedial measures have not been substantially
completed, the inspector shall follow Step 7 discussed below. Photographs of the
violations should be taken and saved.
Step 7: 3r Notice of Violation
10
The inspector issues a Red Tag and a Conditional Stop Work Order upon completion of
the inspection, if one has not already been issued. The Stop Work Order allows for the
resolution of the violation but no other on -site improvements. Building and /or
Occupancy Permits will not be issued and surety /letter of credit reductions will not be
considered or processed until the violation is resolved. Representatives from the
Building and Engineering Departments shall meet to discuss the violation and subsequent
actions. These actions may include: issuing fines for each day of violation since the 1 st
notice of violation; draw from surety to enable the City to have the remedial measures
corrected; seeking United City of Yorkville legal counsel and pursuing injunctive or other
legal relief.
A formal Notice of Violation letter will be sent, via certified mail, to the contractor and
developer. A copy of the Notice of Violation shall also be provided to the Building
Department and City Administrator. The letter will also include additional penalties or
measures that will be imposed if the violation(s) persist. I
Steps 6 and 7 will be repeated until resolution of the violation.
3.3C Measurable Goals
• Track the number of site development permits issued.
• Document any citizen complaints regarding construction site runoff and follow -up
activities.
• Inspect construction sites for erosion/sediment control measures and record
inspection on NPDES/Erosion Control Inspection Report forms.
3.4 Post Construction Runoff Control
The City adopted Ordinance No. 2009 -78 (Appendix 5.4) to establish standards for
design, construction, and maintenance of stormwater best management practices. This
ordinance requires the following:
• All development/redevelopment projects shall incorporate stormwater Best
Management Practices (BMP's) into their site designs.
• Agreements providing for the adequate maintenance of the stormwater BMP's by
the developer /property owner.
• Periodic inspections and meetings with property owners by the city to ensure
proper functioning of the stormwater BMP's.
The City will attempt to inspect approximately 20% of all existing properties with
stormwater management facilities each year, resulting in a recurring inspection interval of
5 years.
11
3.4A Long Term Operation and Maintenance
The SMPP includes two long term maintenance agreements.
• The first agreement (Appendix 5.13) is the recommended plan for existing
detention and stormwater management facilities, whether publicly or privately
maintained. The intent of this sample plan is to provide guidance for the hI
maintenance of facilities that do not have an approved plan. If an existing
facility already has an adequate plan, this document would supersede the
sample plan.
• The second agreement (Appendix 5.14) is provided to applicants during the
permit review period for new detention and stormwater management facilities.
This agreement should be reviewed and enhanced to reflect the specific design
of the new development. Receipt of the signed and recorded maintenance
agreement is required.
Receipt of the signed and recorded maintenance agreement is required prior to recording
of a plat of subdivision, site development permit, or building permit for the property,
whichever occurs first.
3.4B Site Inspections
This section focuses on post - construction inspections of previously developed sites,
streambanks, shorelines, streambeds, and detention / retention ponds.
I
Previouslv Developed Sites
The United City of Yorkville attempts to inspect approximately 20% of all existing
properties with stormwater management facilities every year, resulting in a re- occurrence
inspection interval of five (5) years. Previously developed properties are inspected with
respect to the approved development plan. A letter indicating the maintenance activity
highlights, deficiencies, or modifications to the plan should be provided to the
responsible party. The responsible party is encouraged to implement an annual
maintenance program.
Shorelines
Annually inspect 20% of detention basin shorelines in the spring or fall depending upon
weather conditions using the Storinwater Basin Annual Inspection Report (Appendix
5.15). Observed erosion, seeding/re- seeding or slope stabilization needs are documented.
Documented deficiencies should be reported to the City Engineer who evaluates and
determines appropriate remedial activities. Remedial actions might include notifying the
property owner or including maintenance activities in the city's work program for city -
maintained basins.
Streambanks and Stream Bed Sediment Accumulation
Annually inspect 20% of receiving water streambanks for erosion and flowlines for
sediment plumes /deposits. Inspections should be performed in the spring or fall
depending upon weather conditions. Stream locations are depicted on Figure 1.
12
Document observed erosion and /or sediment accumulation. Documented deficiencies
should be reported to City Engineer who evaluates and determines appropriate remedial
activities. Remedial actions would typically consist of notifying the property owner.
Detention / Retention Pond Sediment Accumulation
Ensure that new detention/retention pond is constructed per the approved development
plan. The developer is responsible for ensuring that the design grade is established prior
to the city's approval of the pond. Pond information, including the design permanent
pool depth, is added to the Storinwater Basin Annual Inspection Report upon final
approval of the pond.
Annually inspect 20% of detention basins to determine the normal pool depth. Observed
depths should be recorded onto the Storinwater Basin Annual Inspection Report. If the
inspected pond depth is found to be more than 2 feet shallower than the design normal
pool depth, this information should be reported to City Engineer who evaluates and
determines appropriate remediation activities.
j
3.4C Measurable Goals
• Annually inspect 20% of all stormwater basins and document on Stornnwater
Basin Annual Inspection Report forms.
• Maintain a database of existing homeowner associations (HOA's). Make contact
with 20% of HOA's annually regarding stormwater - related issues.
• Require new developments to enter into maintenance agreements for their
stormwater management facilities, and maintain a record of those agreements.
• Encourage existing HOA's to inspect and maintain their stormwater management
facilities. Document initial contact and any follow -up activities.
3.5 Illicit Discharge Detection and Elimination
Illicit discharges contribute considerable pollutant loads to receiving waters. There are
two primary situations that constitute illicit discharges; these include non- stormwater
runoff from contaminated sites and the deliberate discharge or dumping of non -
stormwater into the stormwater system. Illicit discharges can enter the storm sewer
system as either an indirect or direct connection.
i
3.5A Regulatory Authority
Effective implementation of an Illicit Discharge Detection and Elimination (IDDE)
program requires adequate legal authority to remove illicit discharges and prohibit future
illicit discharges. This regulatory authority is achieved through adoption of United City
of Yorkville Ordinance No. 2010 -05 (Appendix 5.5). Additionally, IEPA has regulatory
authority to control pollutant discharges and can take the necessary steps to correct or
remove an inappropriate discharge over and above MS4 jurisdiction.
13
3.513 Illicit Discharge Detection and Elimination
The United City of Yorkville maintains, operates, and publicizes a call -in phone number
(630 -553 -4350) where parties can contact the city with environmental concerns. Primary
advertisement venues include the website and all related municipal publications.
Telephone calls received from residents, other internal Departments or other agencies are 4
logged on the Illicit Discharge Tracking Form (Appendix 5.16). The City Engineer, or
his designee, should transfer information from the tracking form to the Illicit Discharge
Sunimmy Form (Appendix 5.17) monthly. The summary form should be reviewed
annually to determine if trends can be seen and if any additional outreach efforts are
warranted.
Subdivision and Public Utilitv Ordinance
The United City of Yorkville created and adopted Ordinance No. 94 -4 (Appendix 5.6) to
prohibit the discharge of any toilet, sink, basement, septic tank, cesspool, industrial waste
or other polluting substances to any open ditch, drain, or drainage structure. This
ordinance can be used to further support the activities required by the city's Stormwater
Management Program Plan.
a
3.5C Understanding Outfalls and Illicit Discharges
Understanding the potential locations and the nature of illicit discharges in urban
watersheds is essential to find, fix and prevent them.
Identifving Outfalls and Receiving Waters
An Outfall is a point source where a municipal separate storm sewer discharges into
Waters of the United States "receiving water ". Open conveyances connecting two
municipal storm sewers, or pipes, tunnels or other conveyances which connect segments
of the same stream or other Waters of the United States are not considered outfalls. For
the purposes of this program the following definitions shall be used:
Outfall: A storm sewer outlet, or other open conveyance point discharge location,
that discharges into a Waters of the U.S, receiving water or another MS4.
Regulated systems include the conveyance or system of conveyances including roads
with drainage systems, municipal streets, catch basins, gutters, ditches, swales, man made j
channels or storm sewers.
The outfall inventory was prepared by the United City of Yorkville. The outfall locations
have been numbered to facilitate detection and tracking of identified illicit discharges.
This information can be obtained from the city's Geographic Information System (GIS),
which is maintained by the Community Development Department.
The outfall map should be revised annually to incorporate permitted outfalls associated
with new developments. An outfall inventory should be performed every 5 years; the
focus of this effort is to search for new outfalls (i.e. those not already included in the
14
I
i
existing GIS). The search for new outfalls should be combined with the pre - screening
efforts.
USEPA Exclusions
It is noted that not all dry- weather flows are considered inappropriate discharges. Under
certain conditions, the following discharges are allowed:
• Water line flushing
• Landscaping irrigation
• Diverted stream flows
• Rising groundwater
• Uncontaminated groundwater infiltration
• Uncontaminated pumped groundwater
• Discharges from potable water sources
• Flows from foundation drains !
• Air conditioning condensation

• Flows from riparian habitats and wetlands
• Dechlorinated swimming pool water i
• Street wash water
Pollutant Indicators
Outfalls should be inspected for evidence of the following pollutant indicators:
• Odor
• Color of discharge water or staining of outfall pipe
• Turbidity (clarity) of discharge water
• Floatables in or residue from discharge water, such as scum, foam, suds, oil
sheen, etc.
• Excessive plant growth or lack of plant growth at outfall
• Sediment plume.
3.51) Indirect Connections
Indirect connections are typically the result of events such as dumping or spillage of
materials into storm sewer drains. Intentional dumping is a common type of illicit
discharge. Generally, indirect modes of entry produce random, infrequent discharges,
with the exception of groundwater seepage.
15
There are five main modes of indirect entry for discharges. These are groundwater
seepage, unintentional spills, intentional dumping, outdoor washing, and over - irrigation
of landscaping.
Seepage discharges can be either continuous or intermittent, depending on the depth of
the water table and the season. Groundwater seepage usually consists of relatively clean
water that is not an illicit discharge by itself, but can carry other illicit discharges. If
storm drains are located close to sanitary sewers, groundwater seepage may intermingle
with sewage. Seepage will be addressed by taking samples to check for contamination
from nearby sanitary sewers or septic systems. Mitigation measures would consist of
repairs to sewers or notification to the Kendall County Health Department as appropriate.
See Chapter 3.6 for the Spill Response Plan for unintentional spills.
Intentional dumping is minimized through public education. The city also maintains an
Illegal Dumping Hotline which is described in Chapter 3.513. The procedure for handling
a dumping incident is described in Chapter 3.6.
Outdoor washing and over - irrigation are minimized through public education.
3.5E Direct Connections
Direct connections enter through direct piping connections to the storm sewer system,
and are most easily detected during dry- weather periods. Inspection of stormwater
outfalls during dry- weather conditions reveals whether non - stormwater flows exist. If
non - stormwater flows are observed, they can be screened and tested to determine whether
pollutants are present. If the presence of pollutants is indicated, the detective work of
identifying the source of the discharge can begin and be corrected.
The process to eliminate direct connection illicit discharges consists of the following
components:
1. Program Planning consists of the organizational efforts required to perform outfall
screening and follow -up investigative activities of the program. Program planning
identifies the regulatory authority to remove directly connected illicit discharges,
identification of the outfalls and receiving waters, and providing personnel and
equipment to perform the outfall screening and follow -up work.
2. Outfall Screening consists of pre- screening to determine whether dry- weather flows
are present and outfall inspection which includes field visits to determine whether an
illicit discharge exists.
3. Follow -Up Investigation and Program Evaluation are necessary to determine the
source of any identified pollutant flows and eliminate them. The major follow -up
investigation evaluation components include:
• reviewing and assessing outfall inspection results
• internal coordination
16
• tracing upstream to identify the source of the illicit discharge
• exercising the appropriate legal means to eliminate the illicit discharge and
schedule follow -up inspections as necessary
3.5F Access to Private Property
In some cases, it may be necessary for City personnel to enter or cross private property to
investigate probable illicit discharges. A form letter should be prepared that includes a
short description of the project, the purpose of the access to the property, and the name of
a project contact person with a telephone number. If the owner is not present, a letter
should be left at the premises to facilitate return inspection: If permission to access
property is denied, a public official should then contact the owner at a later date.
3.5G Confined Space Entry
Confined space entry for this program would include climbing into or inserting one's
head into a pipe, manhole, or catch basin. In general, do not cross the vertical plane ?
defining an outfall pipe or the horizontal plane defining a manhole unless properly
prepared for confined space entry. Confined space entry shall be conducted only by
trained personnel with appropriate rescue and monitoring equipment.
Outfall Inspection
An outfall inspection is required for all submerged outfalls or outfalls observed to have I
dry- weather flow. Outfalls are assessed to determine which one of the three following
conditions applies:
(1) The outfall is dry or damp with no observed flow
(2) Flowing discharges are observed from the outfall
(3) The outfall is partially or completely submerged with no observed flow or is
inaccessible
Scenario 1: No Observed Flow. The field crew should photograph the outfall and
complete applicable sections of the Stormwater Outfall Inspection Form (Appendix
5.18).
Scenario 2: Observed Flow. The field crew photographs the outfall and complete
applicable sections of the Stormwater Outfall Inspection Form. The intent is to gather
additional information to determine if an illicit discharge is present.
Scenario 3: Submersed or Inaccessible Outfall. If standing water is present in an
outfall or if it is inaccessible, then complete available information from Sections 1, 2, 3
and 7 of the Stormwater Outfall Inspection Form, with appropriate comments being
written in the "Remarks" section of the data form.
17
i
Determine the upstream sampling location using the city's stonn sewer atlas. Manholes,
catch basins, or culvert crossings can be used for upstream sampling locations. Make
reasonable efforts to locate upstream sampling points that are accessible and exhibit flow.
If inaccessible, resolve the problem in the office with appropriate supervisory personnel.
Outfall Assessment & Documentation
Complete the Storinwater Outfall Inspection Fora: for all outfall inspections. A I
separate data form must be completed for each outfall. In addition to standard
information, the data form is used to record other information that is noted at the time the
outfall inspection is conducted (e.g. dead or dying plants, fish kills, excessive algae
growth, construction activities, etc. that might provide information regarding the potential
for illicit discharges).
3.5H Office Closeout
Update the outfall screening scheduling and completion form and plan the next screening
day's activities. Discuss any problems locating outfalls with appropriate supervisory
personnel so that alternate sampling locations can be identified. Once a month, compile
data from the Stormwater Outfall Inspection Form onto the Outfall Inspection
Summary Forma (Appendix 5.19).
3.5I Source Identification
Follow -up investigation is required for all outfalls with positive indicators for illicit
discharges. The procedure for detailed investigation and source identification has three
major components: 1) mapping and evaluation, 2) storm sewer investigation, and 3)
tracing.
Manoine Evaluation
For each outfall to be investigated, a large -scale working map should be created to show
the entire upstream storm sewer network, outfall locations, and parcel boundaries.
Storm Sewer Investigation
After conducting the mapping evaluation, a manhole -by- manhole inspection is conducted
to pinpoint the location of the illicit discharge. All flows are tracked upstream until the
dry- weather discharge is no longer detected. The field crew should also determine
whether there has been a significant change in the flow rate between manholes.
Tracing
Once the manhole inspection has identified the reach area, testing may be necessary. If
there is only one possible source to this section of the storm sewer system in the area,
source identification and follow -up for corrective action is straightforward. Multiple
sources, or non - definitive sources, may require testing in order to identify the
contributing source. The method of testing must be approved by the Public Works
Director prior to testing. Potential testing methods include dye testing, smoke testing,
and /or remote video inspections.
18
i
3.5J Removal of Illicit Discharges
Removal of illicit discharge connections is required at all confirmed contributing sources.
Nine steps are taken to positively identify and remove an illicit discharge to the storm
sewer system. These steps are as follows:
Step 1. Have an outside laboratory service take a grab sample and test for the
illicit discharge at the manhole located immediately downstream of the
suspected discharge connection.
Step 2: Conduct an internal meeting with appropriate personnel to include Public
Works personnel, Building Code Official, and the City Engineer to discuss
inspection and testing results and remedial procedures.
Step 3: The City Engineer shall send a notification letter to the owner /operator of
the property /site suspected of discharging a pollutant. The letter should
state the apparent violation, and request that the owner /operator describe
the activities on the site and the possible sources of non - stormwater
discharges including information regarding the use and storage of
hazardous substances, chemical storage practices, materials handling and
disposal practices, storage tanks, types of permits, and pollution
prevention plans.
i
I
Step 4: Arrange a meeting for an inspection of the property with the Building
Code Official and the owner /operator of the property. After inspection,
notify the site owner /operator of the findings and instruct them verbally
and in writing to take any necessary corrective measures.
Step 5: Conduct additional tests as necessary if the initial site inspection is not
successful in identifying the source of the problem. The Public Works
Director is responsible for determining the appropriate testing measure to
pinpoint the source.
Step 6: If the owner /operator does not voluntarily initiate corrective action, the
Building Code Official shall issue a Notification of Noncompliance. The
notification shall include a description of the required action(s) and a time
frame in which to take corrective action. Upon notification of
noncompliance, the owner can be subject to penalties as stipulated by
Municipal Code.
Step 7: Conduct follow -up inspections to determine whether corrective actions
have been implemented to: 1) remove the illicit connection or 2) establish
a proper disposal practice. j
19
Step 8: If corrective actions have been completed (i.e. the illicit discharge has
been eliminated) the City Engineer shall send a notification of compliance
letter to the owner /operator of the property /site where the illicit discharge
occurred.
Step 9: If corrective actions have not been completed additional internal
meetings shall be held to determine appropriate steps to obtain
compliance. Appropriate actions may include monetary or other penalties.
3.5K Program Evaluation
The results of the screening program shall be reviewed periodically to determine if any
trends can be identified that relate the incidence of dry- weather flow observations to the
age of developed properties or land uses. These determinations may guide future outfall
screening activities. Although the outfall screening program will be successful in
identifying and eliminating most pollutants in dry- weather discharges, the continued
existence of dry- weather flows and associated pollutants will require an ongoing
commitment to continue the outfall screening program. The annual inspection screening
will determine the effectiveness of the program.
3.5L Measurable Goals
I
• Track the number and type of potential illicit discharge on the Illicit Discharge
Tracking Forms and Illicit Discharge Suntnrary Forms.
• Inspect all stormwater outfalls annually and record those inspections on the
Stormwater OutfallInspection Forms and Outfalllnspection Summary Fortes.
3.6 Pollution Prevention and Good Housekeeping
The United City of Yorkville is responsible for the care and upkeep of public facilities,
municipal roads, associated maintenance yards, and city parks. Many maintenance
activities are most regularly performed directly by staff; however from time to time
contractors are employed to perform specific activities. This chapter describes how the
compliance with permit requirements is achieved by incorporating pollution prevention
and good housekeeping stormwater quality management into day -to -day operations. On-
going education and training shall be provided to ensure that the appropriate employees
have the knowledge and skills necessary to perform their functions effectively and
efficiently. The following lists describe activities performed by the Public Works
Department and Parks Department.
Street Sweeping
All streets are swept are least 3 times per year or more often on an as- needed basis.
20
Fall Leaf Pick-up
The city provides free leaf pick -up service to residents every fall. Shredded and
compacted leaves are removed and land - applied as fertilizer by a local farmer.
Catch Basin Cleaning
The city owns and operates a vacuum sewer cleaner truck. Catch basin cleaning is
performed on an as- needed basis. Locations of cleaned catch basins are tracked.
Ice Removal
The city uses Geo -Melt (beet juice) additive with salt- spreading operations to reduce the
amount of salt used in the winter, resulting in an average annual reduction in salt usage of
about 500 tons.
Snow Removal
The city does not plow or salt roadways in new developments unless occupied homes
exist along those roadways.
Salt Storage f
The city has a salt storage building on Tower lane to provide protection for stockpiled salt
from rain. After the winter season remaining salt is trucked to the Kendall County storage i
facility for storage until the following winter.
Spill Prevention 1
The city keeps Material Safety Data Sheets for all chemical agents used by the Public
Works Department.
Weed Control
The city uses herbicide when needed to control the growth of vegetation in roadside
ditches. Ditches are mowed where possible to avoid the application of herbicide. The
Public Works Department has several employees that are certified herbicide applicators.
Illicit Connections
Public Works and Engineering Department personnel are instructed to watch for unusual
discharges from storm sewers or unusual events at stormwater basins.
Landscape Maintenance
The Public Works Department and Parks Department are responsible for litter and debris
control, as well as pickup and proper disposal of roadkill. The city shall endeavor to
provide trash/recycling bins in more highly used parks.
Vehicle Maintenance
Vehicle maintenance procedures and practices are designed to minimize or eliminate the
discharge of petroleum based pollutants to the stormwater system. Used motor oil and
antifreeze are collected and stored indoors. Waste fluids are removed on a regular basis
by vendors for recycling. Used batteries are stored in an enclosed covered container at the
Tower Lane maintenance yard. The batteries are collected on a regular basis by a local
21
vendor. Tires are replaced at local commercial vendor sites. Used tires are disposed of by
those vendors.
Waste Management
Waste Management consists of procedural and structural practices for handling, storing
and disposing of wastes generated by a maintenance activity. This helps prevent the
release of waste materials into the stormwater system. Waste management practices
include removal of materials such as asphalt and concrete, excess earth excavation,
contaminated soil, hazardous wastes, and sanitary waste.
A spoil stock pile is located at the Tower Lane maintenance yard. Asphalt, concrete, and
excess earth excavation materials are temporarily stored in the stock pile. Attempts are
made to recycle asphalt and concrete products prior to storage in the spoil stock pile.
Clean spoil is re -used around town where needed to backfill excavations and re -grade
properties. If contaminated spoil is encountered, it is collected for treatment or disposal.
Attempts are made to avoid stockpiling of contaminated spoil. If temporary stock piling
is necessary, the stockpile shall be placed on an impermeable liner. Additional protective
measures shall be used to protect the downslope of the stockpiled area for erosion
downstream. Access to a contaminated stockpile shall be located on the upstream side of
the stock pile.
Hazardous wastes shall be stored in labeled, sealed containers constructed of appropriate
material. The containers are located in non - flammable storage cabinets or on shelving.
These items include paint, aerosol cans, gasoline, solvents and other hazardous wastes.
Paint brushes and equipment used for water and oil -based paints are cleaned within a I
designated cleaning area.
Sanitary wastewater shall be discharged into a sanitary sewer when possible. Portable
toilets shall be maintained at high -usage parks.
Water Conservation
Water conservation practices minimize water use and help to avoid erosion and /or the
transport of pollutants into the stormwater system. Ordinance No. 2006 -123 (Appendix
5.7) limits the use of permanent landscape irrigation systems for certain properties as
follows:
• For non - residential properties with one building, permanent irrigation systems
using city water are prohibited where the total landscaped area exceeds one acre.
• For non - residential properties with more than one building, permanent irrigation
systems using city water are prohibited where the total landscaped area exceeds
three acres.
• For common open space properties of a primarily residential development,
permanent irrigation systems using city water are prohibited.
i
The city has adopted Ordinance 2004 -20 (Appendix 5.8) that establishes odd -even
watering schedules throughout the city based on mailing addresses. This ordinance also
requires a property owner to obtain a watering permit to use city water to establish new
22
lawns. From July 1 St to August 31 watering permits are not issued and city water may
not be used to water newly sodded or seeded lawns. From May 1 St to June 30"', and
September 1 St to September 30 watering permits are issued. Watering on the 1 St day a
lawn is sodded or seeded is limited to no more than eight hours. Watering on the 2" a
through I 01 days is limited to no more than seven hours, those hours being 5am -9am and
9pm to midnight. After Day 10, a lawn is considered established and a permit is no longer
required, however, the property owner must still follow the odd -even and seven -hour
restrictions.
Spill Response Plan
Spill prevention and control procedures are implemented wherever hazardous or non-
hazardous chemicals substances are stored or used. The following general guidelines are
implemented when cleanup activities and safety are not compromised, 'regardless of the
type or location of the spill:
• Cover and protect spills from stormwater run -on and rainfall, until they are
removed
• Dry cleanup methods are used when ever possible
• Properly dispose of used cleanup materials, contaminated materials and recovered
spill material
• Contaminated water used for cleaning and decontamination shall not be allowed
to enter the stormwater system
• Keep waste storage areas clean, well organized and equipped with appropriate
cleanup supplies
• Maintain perimeter controls, containment structures, covers and liners to ensure
proper function
Non - Hazardous Spills/Dumping
Non - hazardous spills typically consist of an illicit discharge of household materials into
the street or stormwater system. Upon notification or observance of a non - hazardous
spill, Public Works personnel implement the following procedure:
• Sandbag the receiving inlet to prevent additional discharge into the storm sewer
system. It may be necessary to sand bag the next downstream inlet.
• Check structures in the immediate and downstream area. If possible, pollutant
materials are vacuumed out. The structures are then jetted to dilute and flush the
remaining unrecoverable material.
• Clean up may consist of applying "Oil Dry" or sand and then sweeping up the
remnant material.
• After containment and cleanup activities have been performed, the Public Works
Director shall fill out the Spill Response Notice (Appendix 5.20) door hanger and
distribute it to adjoining residences/businesses. In residential areas, the hanger
23
I
should be provided to residences on both sides of the spill and on both sides of the
street.
• Public Works personnel document the location, type of spill and action taken on
the Illicit Discharge Tracking Form and submit the tracking form to their
supervisor. The supervisor or his designee takes the information from the form
and transfers it to the Illicit Discharge Summary Form.
• If a person is observed causing an illicit discharge, the Building Code Official
shall be notified and appropriate citations issued.
Hazardous Shills
Upon notification or observance of a hazardous illicit discharge, the Public Works
Department shall implement the following procedure:
• Call 911 and explain the incident. The Fire Protection District responds.
• The Public Works and /or Police Departments provide emergency traffic control.
• The Fire Protection District evaluates the situation and applies "No Flash" or "Oil
Dry" as necessary.
• The Fire Protection District's existing emergency response procedure, for
hazardous spill containment clean -up activities, is followed.
• Public Works personnel document the location, type of spill and action taken on
the Illicit Discharge Tracking Form and submit the tracking form to their
supervisor. The supervisor or his designee takes the information from the form
and transfers it to the Illicit Discharge Summary Form.
Employee Training
The United City of Yorkville's practice is to provide education and training to those
employees of its Public Works and Engineering Departments that have stormwater-
related responsibilities to ensure that they have the knowledge and skills necessary to
perform their functions effectively and efficiently. Employees are encouraged to attend
training sessions on topics related to the goals /objectives of the SMPP. Additionally, the
Public Works Director will develop an employee training programs with curricula and
materials tailored to specific employees. The materials will focus on stormwater pollution
prevention measures and practices relating to the maintenance of facilities, infrastructure
and properties.
The initial training program will be offered within one year of the acceptance of the
SMPP. Copies of training materials will be kept and shared with appropriate new
employees as part of their job introduction. The Public Works Director will monitor the
potential need for overall refresher material distributions and offer additional training as
necessary.
24
f
3.6A Measurable Goals
• Maintain records for number curb miles swept each year.
• Maintain records on amount of leaves collected each fall.
• Maintain records on amount of road salt used each winter.
• Maintain records for number of catch basins cleaned.
• Maintain records for amount of herbicides and pesticides used each year.
• Maintain records on type and number of training sessions and employees in
attendance.

4 Program and Performance Monitoring, Evaluation, &
Reporting
The SMPP represents an organized approach to achieving compliance with the
expectations of the NPDES Phase II program for both private and public activities within
the United City of Yorkville. Land development and city projects and activities are to
comply with the SMPP. Additionally, the city has numerous written and unwritten
procedures for various tasks. This SMPP documents and organizes previously existing
procedures to create one cohesive program addressing pre - development, construction,
and post - development activities, as well as municipal operations.
This chapter describes how the United City of Yorkville will monitor and evaluate the
SMPP. As part of the stormwater management program, the city will:
• review its activities
• inspect its facilities
• oversee, guide, and train its personnel
• evaluate the allocation of resources available to implement stormwater quality
efforts
This chapter describes how program monitoring, evaluation and reporting will be
accomplished.
4.1 Performance Milestones
Previously established ordinances and programs implement many of the anticipated tasks.
The following schedule describes general performance expectations.
• Within one year following the acceptance of the SMPP, appropriate employees
will receive training regarding the implementation of the SMPP.
• Within one year following the acceptance of the SMPP, items within Chapter 3
will be implemented with the exception of the IDDE program milestones
discussed below. Refer to Chapter 2.1 for a description of tasks associated with
the implementation of the SMPP.
• Within three years following the acceptance of the SMPP, the Outfall Inspection
Procedure will be completed for all pipes identified, during the pre- screening
efforts, as having dry weather flow.
• Within five years following the acceptance of the SMPP, tracing and removal
procedures will be completed for all sewers identified during the Outfall
Inspection Procedure as having illicit discharges.
26
i
4.2 Program Monitoring and Research
Currently water quality sampling/monitoring is not required under the NPDES Phase II
program. Therefore, monitoring efforts focus on qualitative, not quantitative,
examination of stormwater practices. It is anticipated that the USEPA and IEPA
programs will evolve to require water quality monitoring and sampling. Future efforts
may involve collecting information regarding discharges from outfalls, identifying other
sources of pollutants, characterizing the receiving waters, sampling construction site
discharges, and identifying the performance of stormwater pollution control measures.
The United City of Yorkville will comply with future federal and state mandates
regarding stormwater issues.
The United City of Yorkville will consider research conducted by others regarding the
effectiveness of various alternative stormwater practices, procedures and technologies.
The city will continue to seek innovative stormwater practices and technologies.
f
4.3 Program Evaluation
The primary mechanism for evaluating the SMPP and ensuring that the field staff has
adequate knowledge is supervision by responsible managers. Management personnel
include the directors and supervisors of the Public Works and Engineering Departments.
Management support tasks include observing and evaluating design, construction, and
field personnel as they implement the requirements of the SMPP on both municipal and
private projects, and maintenance personnel as they conduct their assigned activities.
The following types of questions /answers are discussed annually between management
and field staff.
• Are proper stormwater management practices used in planning, designing and
constructing both city and private projects?
• Are efforts to incorporate stormwater practices into maintenance activities
effective and efficient?
• Is the training program sufficient?
• Is the SMPP sufficient?
• Are the procedures for implementing the SMPP adequate?

100.0 Findinas and Purpose,
101.0 Findings:
The City Council of the City hereby finds that:
101.1 Excessive quantities of soil may erode from areas undergoirt"evelopment for certain non - agricultural
uses including but not limited to the construction of dwelling units, commercial buildings and industrial
plants, the building of roads and highways, the modification of stream channels and drainage ways,
and the creation of recreational facilities;
101.2 The washing, blowing, and falling of eroded soil across and upon - roadways endangers the health and
- safety of users thereof, by decreasing vision and reducing traction of road vehicles;
101.3 Soil erosion necessitates the costly repairing of gulleys, washed -out fills, and embankments;
101.4 Sediment from soil erosion tends to clog sewers and ditches and to pollute and silt rivers, streams, i
lakes, wetlands, and reservoirs;
101.5 Sediment limits the use of water and waterways for most beneficial purposes, promotes the growth of
undesirable aquatic weeds, destroys fish and other desirable aquatic life, and is costly and difficult to
remove; and
101.6 Sediment reduces the channel capacity of waterways and the storage capacity of floodplains and
natural depressions, resulting iii increased chances of flooding at risk to public health and safety.
102.0 Purpose:
The City Council therefore declares that the purpose of this ordinance is to safeguard persons, i
protect property, prevent damage to the environment, and promote the public welfare by guiding,
regulating and controlling the design, construction, use and maintenance of any development or other
activity that disturbs or breaks the topsoil or otherwise results in the movement of earth on land- situated
in the City. It is the intention of this ordinance that the delivery of sediment from sites affected by land
disturbing activities be limited, as closely as practicable, to that which would have occurred if the land
had been left in its natural undisturbed state.

300.0 General Princiales,
It is the objective of this ordinance to control soil erosion and sedimentation caused by development
activities, including clearing, grading, stripping, excavating, and filling of land, in the city. Measures
taken to control soil erosion and offsite sediment runoff should be adequate to assure that sediment is
not transported from the site by a storm event of ten -year frequency or less. The following principles
shall apply to all development activities within the city and 16 preparation of the submissions
required under Section 400.0 of this ordinance:
300.1 Development should be related to the topography and soils of the site so as to create the least
potential for erosion. Areas of steep slopes where high cuts and fills may be required should be
avoided wherever possible, and natural contours should be followed as closely as possible.
300.2 Natural vegetation should be retained and protected wherever possible. Areas immediately adjacent
to natural watercourses, lakes, ponds, and wetlands should be left undisturbed wherever possible.
Temporary crossings of watercourses, when permitted, must include appropriate stabilization
measures.
300.3 Special precautions should be taken to prevent damages resultant from any necessary development
activity within or adjacent to any stream, lake, pond, or wetland. Preventative measures should reflect
the sensitivity of these areas to erosion and sedimentation.
300.4 The smallest practical area of land should be exposed for the shortest practical time during
development.
300.5 Sediment basins or traps, filter barriers, diversions, and any other appropriate sediment or runoff control
measures should be installed prior to site clearing and.grading and maintained to remove sedimentfrom
run -off waters from land undergoing development.
300.6 The selection of erosion and sedimentation control measures should be based on assessment of the
probable frequency of climatic and other events likely to contribute to erosion, and on evaluation of the
risks, costs, and benefits involved.
300.7 In the design of erosion control facilities and practices, aesthetics and the requirements of continuing
maintenance should be considered.
300.8 Provision should be made to accommodate the increased run -off caused by changed soil and surface
conditions during and after development. Drainage ways should be designed so that their final gradients
and the resultant velocities and rates of discharge will not create additional erosion onsite or downstream.
300.9 Permanent vegetation and structures should be installed and functional as soon as practical during
development.
300.10 Those areas being converted from agricultural purposes to other land uses should be vegetated with
an appropriate protective cover prior to development.
300.11 All waste generated as a result of site development activity should be properly disposed of and
prevented from being carried off the site by either wind or water.
300.12 All construction sites should provide measures to prevent sediment from being tracked onto public or
private roadways.

503.0 Site Desion Reouirements,
503.1 On -site sediment control measures, as specified by the following criteria, shall be constructed and
functional prior to initiating clearing, grading, stripping, excavating.or fill. activities on the site:
a. For disturbed areas draining less than 1 acre, filter barriers (including filter fences, straw bales, or
equivalent control measures) shall be constructed to control all offsite runoff as specified in
referenced handbooks. Vegetated filter strips, with a minimum width of 25 feet, may be used as
an alternative only where runoff in sheet flow is expected;
b. For disturbed areas draining more than 1 but less than 5 acres, a sediment trap or equivalent control
measure shall be constructed at the downslope point of the disturbed area;
c. For disturbed areas draining more than 5 acres, a sediment basin or equivalent control measure shall
be constructed a t the downslope point of the disturbed area;
d. Sediment basins and sediment traps designs shall provide for both detention storage and
sediment storage. The detention storage shall be composed of equal volumes of "wet" detention
storage and "dry" detention storage and each shall be sized for the 2 -year, 24 -hour runoff from the
site under maximum runoff conditions during construction. The release rate of the basin shall be
that rate required to achieve minimum detention times of at least 10 hours. The elevation of the
outlet structure shall be placed such that it only drains the dry detention storage; and
e. The sediment storage shall be sized to store the estimated sediment load generated from the site
over the duration of the construction period with a minimum storage equivalent to the volume of
sediment generated in one year. For construction periods exceeding 1 year, the 1 -year sediment
load and a sediment removal schedule may be substituted.
503.2 Stormwater conveyance channels, including ditches, swales, and diversions, and the outlets of all
channels and pipes shall be designed and constructed to withstand the expected flow velocity from the
10 -year frequency storm without erosion. All constructed or modified channels shall be stabilized
- within 48 hours, consistent with the following standards:
a. For grades up to 4 percent, seeding in combination with mulch, erosion blanket, or an equivalent
control measure shall be applied. Sod or erosion blanket or mat shall be applied to the bottom of the
channel.
b. For grades of 4 to 8 percent, sod or an equivalent control measure shall be applied in the channel.
c. For grades greater than 8 percent, rock, riprap, or an equivalent control measure shall be applied,
or the grade shall be effectively reduced using drop structures.
Page 11 of 15
March 5, 2003
503.3 Disturbed areas shall be stabilized with temporary or permanent measures within 7 calendar days
following the end of active disturbance, or redisturbance, consistent with the following criteria:
a. Appropriate temporary or permanent stabilization measures shall include seeding, mulching,
sodding, and /or non- vegetative measures, and
b. Areas having slopes greater than 12 percent shall be stabilized with sod, mat or blanket in
combination with seeding, or equivalent.
503.4 Land disturbance activities in stream channels shall be avoided, where possible. If disturbance activities
are unavoidable, the following requirements shall be met:
a. Construction vehicles shall be kept out of the stream channel to the maximum extent practicable.
Where construction crossings are necessary, temporary crossings s4gll be constructed of non - erosive
material, such as riprap or gravel;
b. The time and area of disturbance of stream channels shall be kept to a minimum. The stream
channel, including bed and banks, shall be restabilized within 48 hours after channel disturbance is
completed, interrupted, or stopped; and
c. Whenever channel relocation is necessary, the new channel shall be constructed in the dry and
fully stabilized before flow is diverted.
503.5 Storm sewer inlets and culverts shall be protected by sediment traps or filter barriers meeting accepted
design standards and specifications.
503.6 Soil storage piles containing more than 10 cubic yards of material shall not be located with a down-
slope drainage length of less than 25 feet to a roadway or drainage channel. Filter barriers, including
straw bales, filter fence, or equivalent, shall be installed immediately on the downslope side of the
piles.
503.7 If de- watering devices are used, discharge locations shall be protected from erosion. All pumped
discharges shall be routed through appropriately designed sediment traps, basins, or equivalent.
503.8 Each site shall have graveled (or equivalent) entrance roads, access drives, and parking areas of
sufficient length and width to prevent sediment from being tracked onto public or private roadways.
Any sediment reaching a public or private road shall be removed by shoveling or street cleaning (not
flushing) before the end of each workday and transported to a controlled sediment disposal area.
503.9 All temporary and permanent erosion and sediment control practices must be maintained and repaired
as needed to assure effective performance of their intended function.
503.10 All temporary erosion and sediment control measures shall be disposed of within 30 days after final
site stabilization is achieved with permanent soil stabilization measures. Trapped sediment and
other disturbed soils resulting from the disposition of temporary measures should be permanently
stabilized to prevent further erosion and sedimentation.
504.0 Handbooks Adopted by Reference:
The standards and specifications contained in Standards and Specifications for Soil Erosion and
Sediment Control' (the Yellow Book) and the "Illinois Procedures and Standards for Urban Soil
Erosion and Sedimentation Control' (the Green Book) cited in Section 400.0, are hereby
incorporated into this Section 500.0 and made a part hereof by reference for the purpose of

505.0 Maintenance of Control Measures:
All soil erosion and sediment control measures necessary to meet the requirements of this
ordinance shall be maintained periodically by the applicant or subsequent landowner during the
period of land disturbance and development of the site in a satisfactory manner to ensure adequate
performance.
506.0 Inspection:
The (permitting authority) shall make inspections as hereinafter required and shall either approve
that portion of the work completed or shall notify the permittee wherein the work fails to comply with
the site development or erosion and sedimentation control plan as approved. Plans for grading,
stripping, excavating, and filling work bearing the stamp of approval of the (permitting authority)
shall be maintained at the site during progress of the work. In order to obtain inspections and to
ensure compliance with the approved erosion and sediment control plan, the grading or building
permit, and this Ordinance, the permittee shall notify the (permitting authority) within two (2) working
days of the completion of the construction stages specified below:
1. Upon completion of installafion of sediment and runoff control measures (including perimeter controls
and diversions), prior to proceeding with any other earth disturbance or grading,
2. After stripping and clearing,
3. After rough grading,
4. After final grading,
5. Aftef seeding and landscaping deadlines, and
6. -After final stabilization and landscaping, prior to removal of sediment controls.
If stripping, clearing, grading and /or landscaping are to be done in phases or areas, the permittee shall
give notice and request inspection at the completion of each of the above work stages in each phase or
area. If an inspection is not made and notification of the results given within five working days after
notice is received by the City from the permittee, the permittee may continue work at his/her own risk,
without presuming acceptance by the (village). Notification of the results of the inspection shall be given
in writing at the site.
507.0 Special Precautions:
507.1 If at any stage of the grading of any development site the (permitting authority) determines by
inspection that the nature of the site is such that further work authorized by an existing permit is
likely to imperil any property, public way, stream, lake, wetland, or drainage structure, the
(permitting authority) may require, as a condition of allowing the work to be done, that such
reasonable special precautions to be taken as is considered advisable to avoid the likelihood of
such peril. "Special precautions" may include, but shall not be limited to, a more level exposed
slope, construction of additional drainage facilities, berms, terracing, compaction, or cribbing,
installation of plant materials for erosion control, and recommendations of a registered soils
engineer and /or engineering geologist which may be made requirements for further work.

March 5, 2003
507.2 Where it appears that storm damage may result because the grading on any development site is not
complete, work may be stopped and the permittee required to install temporary structures ortake such
other measures as may be required to protect adjoining property or the public safety. On large
developments or where unusual site conditions prevail, the (permitting authority) may specify the time
of starting grading and time of completion or may require that the operations be conducted in specific
stages so as to insure completion of protective measures or devices prior to the advent of seasonal
rains.
508.0 Amendment of Plans:
Major amendments of the site development or erosion and sedimentation control plans shall be
submitted to the city engineer and shall be processed and approved. -or disapproved in the same
manner as the original plans. Field modifications of a minor nature may be authorized by the city
engineer by written authorization to the permittee.

Exhibit 1
RESOLUTION FOR THE
UNITED CITY OF YORKVILLE
STANDARD SPECIFICATIONS FOR EVIPROVEMENTS
Resolution No. py'3
These Standards apply to all infrastructure improvements, and may be modified as needed upon the advice
of the City Engineer for special identified situations or conditions. All contractors shall give the City
Engineer's office a minimum 48 -hour notice of all work and of all required approvals. Failure to obtain
these required approvals will require extensive testing, removal and replacement, and a ban for a minimum
of one year, from working on the City's right -of -way. Subdividers that have been unfaithful in previous
City agreements or developments, or who owe the City payments, will not be allowed to have work
performed for them within the public right -of -way. Resident engineering inspection shall be provided
through the City Engineer's office, and all such costs shall be charged to the developer by the United City
of Yorkville. Required written approvals will not be given until bills are paid in full. The
developer's improvement Letter of Credit or other subdivision securities will also be liable for all such
costs. The developer shall be responsible for layout and staking engineering., as well as for record drawings
by a registered Professional Engineer. These Specifications for Improvements shall become a part of each
and every project approved by the United City of Yorkville, and no other specifications will take
precedence.
All improvements included in the United City of Yorkville's Standard Specifications for Improvements,
unless noted herein, shall conform to the latest editions of the State of Illinois "Standard Specifications for
Road and bridge Construction ", the "Manual on Uniform Traffic Control Devices ", and all amendments
thereto. These documents shall be considered as included within the City of Yorkville Standard
Specifications for Improvements, and in the case of a conflict of requirements, the most stringent shall
apply.
Prior to starting construction of any project, the developer shall attend a pre - construction meeting and bring
a representative from each contractor, a list of all contact persons that can be reached at any time, and a
complete schedule of all work to be performed.
No work is to start until the City Engineer and the City Administrator have approved the engineering plans,
and the pre - construction meeting has been held. The City Engineer must approve any changes to the
approved plans in writing. The City Engineer or a representative will, upon discovery of improper material
or installation practices, issue a written document to the contractor, stating that failure to stop and correct
such deficiencies will result in the City's refusal to accept such improvements of to issue any further
building permits, or to perform required inspections.
The subdivider shall obtain and keep in force insurance coverage for Worker's Compensation, and
Employer's Liability, Commercial General Liability, Commercial Automobile Liability, and Umbrella
Liability, as described in IDOT's "Standard Specifications for Road and Bridge Construction ". The United
City of Yorkville shall be named as an additional insured. The insurance coverage shall remain in effect
until the City accepts the entire development.
The City will not consider acceptance of the public improvements in a development until it is at least fifty
(50) percent built out, or three years after the roadway binder course is paved, whichever is sooner.
Blasting will not be allowed.

Standard Specifications for Improvements
ROADS
All roadways shall conform to the Illinois Department of Transportation (hereinafter termed IDOT) }
"Standard Specifications for Road and Bridge Construction ", unless modified herein. Horizontal and
vertical geometric for right -of -ways and roadways shall conform to the City Standards, listed in Figure 2.
Surface course must not be placed until at least seventy- (70 %) percent of the adjacent, private
improvements are in place. However, in no case shall the surface course be placed until the binder course
has been in place for at least one full winter season. In no case shall the surface course be delayed more
than three (3) years after the binder course has been installed.
The subgrade shall be graded and compacted to a hard, uniform surface, matching the slopes of the surface
course. It shall have no rutting and shall completely drain to the outer edges. It shall be proof rolled by the
contractor with a fully loaded (gravel) 10 -cubic yard dump truck and witnessed by and approved in writing
by the City Engineer's representative (hereafter termed City Engineer) before proceeding to build the
roadway. All unsuitable subgrade shall be removed and replaced with compacted, stable clay material or
shall be replaced with compacted CA6 limestone on an approved, non -woven roadway fabric (6.5 oz.
minimum). Other geo -grids may be required for certain conditions. All bituminous mixtures shall be
delivered and handled so that the bituminous mixture immediately behind the paver screen is at or above
270 degrees F. All asphalt delivered to the project shall be covered when the temperature is at or 70
degrees F.
All subgrades, other than approved granular subgrades, shall be completely covered with a subgrade fabric
(Amoco 4551 or approved equal), with a full 18 inches of overlap. Subgrade Fabric shall also be used on
lime - stabilized sub grades. It shall be placed neat and tight, without wrinkles, tears, or defects.
Construction equipment shall not be allowed to drive on the fabric until it has a minimum of four inches
cover of granular base material. The City Engineer shall approve in writing the subgrade fabric
installation prior to placing base material. The subgrade fabric shall extend a minim of twelve inches `
beyond the back of each curb. `
f
In areas where undercutting of the subgrade is required, the bottom of the excavation shall be lined with a
woven geotextile (Amoco 2002 or approved equal), and backfilled with CA -3 aggregate.
The aggregate base course shall be compacted to a minimum of 95% Modified Proctor and shall be free of
all dirt and debris. The course shall be proof rolled, as described above, and witnessed by and approved in
writing by the City Engineer before proceeding to build the roadway. A bituminous prime coat shall be
applied to the aggregate base course prior to paving.
The bituminous . concrete binder course shall be placed only upon the written approval of the City Engineer.
All asphalt must be laid utilizing a good - quality, properly - functioning, tracked or wheeled asphalt laying
machine, utilizing fully- automatic, electronic sensing control from a stringline for the initial course, and
from a minimum fifteen (15') foot ski for all other lifts. The bituminous binder course shall be proof rolled
as described above, and witnessed by, and approved in writing, by the City Engineer before proceeding
with the surface course. All repairs must be made as directed by the City Engineer. All bituminous
pavement patches shall be at least fifty (50 %) percent thicker than.the pavement being patched.
Also, the binder course shall be bump tested by the contractor, and witnessed by the City Engineer, and all
areas exceeding one -half inch (1/2 ") bumps, including header joints and any patch joints, shall receive a
leveling course prior to surfacing. Areas of excessive patching will automatically receive a level course
prior to surfacing. Prior to any leveling course or surface course, the streets shall be flushed clean and free
of all dirt and debris. A bituminous tack coat will be required. Minimum temperature requirements for
laying asphalt will be 5 degrees F higher than that allowed by IDOT specifications.
S -2
Standard Specifications for Improvements
The bituminous concrete surface course shall be placed only upon the written approval of the City
Engineer. All asphalt must be laid utilizing good - quality, properly functioning, tracked or wheeled asphalt
laying machine, utilizing fully automatic, electronic sensing control from a minimum 15 -foot ski. The
surface course shall be bump tested by the contractor, and witnessed by the City Engineer. All bump test
penalties specified by IDOT specifications shall be quadrupled, and areas that have an excessive amount of
one -half inch (1/2 ") bumps shall be completely removed and replaced, not just the bump itself. Minimum
temperature requirements for laying bituminous surface course will be five (5) degrees F higher than that
allowed by IDOT specifications. The surface elevation of the asphalt at the concrete gutter shall be % inch
higher than that of the adjacent concrete. All streets shall have a oross''`slope of 2% from the centerline to
the concrete curb.
Areas of segregated binder course and/or surface course shall be removed and replaced at the direction of
the City Engineer. Segregated asphalt is the uneven distribution of course and fine materials in the asphalt
characterized by pavement textures different from the surrounding material, and can usually be seen by the
naked eye.
Pavements constructed from Portland Cement Concrete shall be designed in conformance with American
Concrete Pavement Association Publications IS 184P and IS 061P, as amended.
Combination concrete curb and gutter will be required- on all roadways. All curb and gutter shall be placed
on an aggregate base with a minimum thickness of four inches, but in no case shall the curb and gutter
subgrade be higher than one inch below the adjacent roadway subgrade. The height of the gutter flag shall
be ten (10 ") inches, unless directed otherwise by the City Engineer. As noted previously, the roadway
subgrade fabric will extend over the curb and gutter subgrade, and beyond by a minimum of twelve (12 ")
inches. The concrete curb and gutter shall be reinforced with two #4 deformed bars, placed three (3")
inches from the bottom, spaced twelve (12 ") inches apart, centered on the total width of the curb and gutter.
Machine- placed concrete curb and gutter is to be utilized wherever practical, utilizing a minimum Class X
concrete, and a five (5 %) percent minim air- entrainment. Plastizers will be allowed, but chlorides will
not. An approved spray -on curing compound with red fugitive coloring shall be applied immediately after I
finishing, and a sealer, WR Meadows TIAC, or approved equal, shall be applied after seven days. The
resident engineer shall be notified of these applications, and proof of purchase, with material specifications, j
will be required. The concrete curb and gutter shall have the required slip bar expansion joints, and 3 / inch
deep sawed contraction joints will be required every 15 -20 feet, within 24 hours after each pour. Minor
honeycombing on the two outer, vertical surfaces will be allowed, but they must be patched in an approved
manner, and witnessed by the City Engineer, prior to backfilling. The clay backfill behind the curb shall be
placed and compacted prior to placing aggregate base course.
Roadway extensions and stubs will be required as part of the development, with full improvements where
needed, for future growth. Additional lanes, access improvements, traffic signalization, etc., may be
required, at the developer's expense. The developer shall reimburse the City for two of each street name
and regulatory signs and posts required, and the City will install them. All signs shall be high- intensity, as
approved by the Director of Public Works. All pavement markings shall be thermoplastic. The developer
shall reimburse the City for the cost of replacing any signs that are missing, stolen, or damaged prior to
final acceptance.

Multiple collection lines of four inch and six inch HD PVC will be allowed by an approved design.
Terminal and junction points shall be at two -foot diameter precast concrete inlets with open -lid castings.
The pipe from the house shall be a 2" minimum HD PVC with cemented joints. The connection to the
storm sewer shall be through a neat, tight fitting, bored hole into the concrete pipe. After insertion of the
sump pump discharge pipe into the concrete storm sewer pipe, the joint shall be sealed with hydraulic
cement. In no case shall the sump pump discharge pipe extend beyond the inner surface of the concrete
storm sewer pipe. Connections, however, shall be into a structure wherever practical.
Individual storm sewer services shall not be required in areas of the development where soil and ground
water conditions indicate that sump pumps would run very infrequently. If the developer does not wish to
install storm sewer services, he shall perform soil borings at regular intervals (300' to 400' grid typical)
during the Final Plan preparation stage, to determine soil types and ground water elevations. Boring
locations are subject to approval by the City. Each boring shall extend at least 20 feet below existing
ground elevations and be referenced to the development benchmarks. If the boring logs show granular soil
and also show ground water elevations at least five (5') feet below planned basement floor elevations, then
individual storm sewer services shall not be required in that area of the development. During excavation of
every basement in that area, the developer shall verify (with City representative present) that the granular
soil and deep ground water conditions exist. If either condition is found not to exist at a building location,
the developer shall construct a storm sewer service to that building, in conformance with these Standard
Specifications.
The design of the storm water collection system shall be for a ten (10) year storm, running just full. The
only exception to this is where the receiving storm water system has less capacity and here the new system
of conduits shall be designed for a five (5) year event, running just full. The minimum velocity shall 2.5
fps and the maximum shall be 8 fps. The storm sewer pipe shall have a minimum cover of three (3') feet.
Storm sewer manholes shall be five (5') feet internal diameter, constructed of reinforced concrete, and shall

For developments ten acres in size or larger, the developer may use computer -based methods to determine
stormwater storage volumes. The specific method and parameters used in employing the method shall be
subject to the approval of the City Engineer.
For developments less than ten acres in size, the storm water storage system shall be designed utilizing a
Modified Rational Method, as described below:
1. Q = (Cm) iA, where a run -off co- efficient or-Ca is calculated for the site bas ed upon actual
proposed surface coverage. Cm then - equals 1.25 tines Ca.
2. The following run -off co- efficient shall be utilized as minimums:
Surface C
Grass .50
Asphalt/Concrete .98
Roof 1.00
Detention 1.00
3. The maximum release at the designated 100 -year level is 0.15 cfs /acre. The City Engineer
shall reduce this allowable release rate where the downstream accepting system is
experiencing drainage problems such as the Elizabeth Street swale where all receiving
discharges are limited to 0.10 cfs /acre. The outlet structure design shall address the two -year
(0.04 cfs /acre) and the 25 -year (0.08 cfs /acre) storm control, in addition to the 100 -year event.
i
4. When depressional compensatory storage is provided by increasing the volume of a
stormwater detention basin, the maximum allowable release rates of the basin shall be
reduced, as directed by the City of Yorkville to approximate the pre - development release of
the depressional area, and realize the full storage potential of the enlarged basin.
5. The minimum size restrictor shall be a four -inch by twelve -inch long HD PVC pipe. The
design must be designed for easy maintenance and cleaning during a storm event. The
discharge shall be directly to a downstream storm sewer if one is available within a reasonable
distance. If not, the discharge will be to the surface, with approved energy dissipation and
downstream erosion protection.
6. The rainfall intensities to be utilized are those established by the Illinois State Water Survey's
Bulletin #70, as amended for the specific City of Yorkville area. In designating the required
storm water storage volumes, the maximum value calculated using the various events should
be utilized. See Figure 3 for a sample calculation.
7. The storm water storage areas must have containment for twelve inches of additional storm
water storage, with an approved calculated overflow area at six inches above calculated 100 -
year elevation. This overflow shall have an erosion concrete curtain wall, with a minim
thickness of 8 inches, a minimum depth of three feet below grade, and a length to extend a
minimum of four feet beyond the limits of the overflow on either end. This wall is not to be
formed, but is to be trenched or excavated into natural soil, or into the compacted fill, and is
to be finished flush to the ground.
8. Storm water storage areas shall be covered by an easement, including access thereto, such that
should the owner not maintain said area as necessary, the City can cause such corrections and
bill the owner, including any and all administrative costs.

9. The engineering plans shall have a full sheet dedicated to the soil erosion and sedimentation
control requirements for the development, including silt fencing, straw bales, drainage fabric,
etc. Failure to properly maintain this system may result in major storm sewer cleaning within
the site and in the offset storm system. The City reserves the right to place a hold on all
building permits and inspections if the soil erosion and sedimentation control plan is not
properly maintained. Keeping the streets clean is part of this plan, and failure to do so will
result in these actions. The developer shall establish a Street Cleaning deposit with the City of
Yorkville, in the amount of $5000.00. If the streets.are not cleaned within 48 hours of a
written request by the Director of Public Works, the. 'y "shall have the streets cleaned, and
subtract that cost from the deposit. The developer shall replenish the deposit to the full
amount if it falls to less than $1000.00. The Yorkville City Council shall return any unused
portion of the deposit to the developer upon acceptance of the streets.
10. The developer shall establish basins onsite where concrete ready -mix trucks must wash out
after delivering their load. Signs shall be posted at each entrance to the development to warn
truck drivers of the requirement to wash out at specific sites, and notify them of the fine for f
non- compliance (up to $100.00 for each offense). Each entrance sign shall include a
simplified map of the development, to show the locations of the washout basins in the
development. A sign shall also be posted at each washout basin, to identify the site. The
developer shall maintain all signs, basins, and appurtenances in good condition until the City
accepts the public improvements.
Washout basins shall be located outside of the public right -of -way, parks, and all public utility
easements. They shall be located in relatively low - traffic areas, and be at least fifty- (50') feet
from storm drains, open drainage facilities, and watercourses, unless approved otherwise by
the City Engineer. Basins shall have a minimum twelve (12 ") inch thick CA -3 aggregate
approach of sufficient width over a woven geotextile fabric, to reduce tracking of mud onto
roadways. The washout area shall be contained by an earthen berm, and be at least ten (10')
wide by ten (10') long. The maximum depth of a washout basin shall be three feet. When the
volume of a washout basin is 75% full, the developer shall remove the hardened concrete and
transport it to a legal landfill. Burying waste concrete onsite shall not be permitted.
The developer shall incorporate the items necessary to comply with this requirement, as well
as provisions for maintenance, onto the erosion and sediment control plan sheet. All signage,
washout basins, and appurtenances shall be in place before the first building permit is issued.
11. The engineering plans shall have one or more full sheets dedicated to the Final Grading of the
entire site. The minimum grade for all grass areas shall be two (2 %) percent, except that
swale areas may be at one (1 %) percent if it is over an approved, piped underdrain. Slopes
shall be shown with arrows at all locations from all break points. A grading plan on an 8 -1/2"
x 11" paper for the actual building must be submitted for each building permit submitted, and
will become a part of the building permit. All top of foundation elevations will be a minimum
of two (2') feet, and a maximum of three (3') feet above the street centerline elevation,
measured at the center of the lot in question, unless the City Engineer directs otherwise, based
on site - specific conditions. Drives must be at a minim slope of two (2 %) percent, and
maximum slope of eight (8 %) percent towards the curb flow line from the garage. When the
forms for the foundation are ready to pour, a top of foundation elevation and location
certification of a registered surveyor or engineer, as approved by the building inspector, is
required prior to pouring the concrete into the forms. The tolerance here is 0.15 feet lower
and 0.5 feet higher, and behind all applicable setback and easement lines.

12. Requests for an occupancy permit must include an as -built grading plan, signed and sealed by
a registered land surveyor, showing the original, approved grades and slopes, along with the
actual grades, just prior to the occupancy permit request. The actual grades must fall within a
tolerance of 0.15 feet in order to receive an occupancy permit. Top soiling and seeding or
sodding, if applicable, must be in place prior to the final grading plan. All City - incurred costs
of reviewing these grading plans shall be the responsibility of the developer. Note that
specific building codes, ordinances, and permitting procedures, which may be established by
the United City of Yorkville, shall supersede these requirements.
13. General grading and landscaping of the storm water areas shall be designated according to the
Park Development Standards, Landscape Ordinance, and these Standard Specifications. The
City may require that storm water detention and retention facilities, as well as grading,
landscaping, and stormwater collection systems, incorporate currently acknowledged Best
Management Practices to improve storm water quality. These may include, but are not
limited to, naturalized detention basins, bio- swales, low impact design standards, perforated
storm sewer, designs that reduce the degree of connected impervious areas, designs that
encourage infiltration of stormwater, etc.
Wet ponds shall have a maximum allowable depth of two feet between the normal water level
and the. high water level corresponding to the Ten -Year Frequency Storm. The City may
require wetland -type plantings and appropriate grading around the perimeter of wet ponds.
The developer shall provide a soil report, prepared by a licensed professional engineer, to
determine whether or not lake lining will be required. Vertical or nearly vertical edge
treatment will require an approved method, allowing a child to easily climb out of the water.
Storm sewers discharging to a stormwater basin shall be designed such that the sewer invert at
the discharge point is no lower than 6" below the normal water level of the basin, and the top
of sewer is no lower than the ten -year high water level of the basin.
14. Storm water storage basins shall operate independently of any watercourse or water body
receiving the discharge from the basins. Bypass flows from upstream areas should bypass the
storm water storage facility, where practical. The entire development shall be examined
under the premise that all storm sewers are blocked and full when a 100 -year event occurs,
and the development can pass these flows without flooding homes. All overflows are to be
contained within the right -of -way, or where absolutely necessary, through special drainage
easements. All buildings shall have the lowest water entry a minimum of 1.8 inches above the
elevations determined for this bypass situation.
15. Storm water detention shall not be required under the conditions listed below: The City
reserves the right to require detention on any parcel of land if special circumstances exist, and
to require that sewer be constructed as necessary, to carry away the storm water.
a) Proposed development or re- development of the existing lots zoned single -
family detached, or duplex residential, less than 2.5 acres in gross area.
b) Proposed development or re- development of existing lots zoned other than
single - family detached or duplex residential, that are less than 1.25 acres in

determined by the traffic generated from the site, the trip distribution of traffic, and the trip
assignment of the traffic generated by the development over the surrounding area road network.
EXISTING AM. PM. & TOTAL DAILY TRAFFIC VOL ES: Existing AM, PM, and total
daily traffic volumes for access driveways (if existing), intersections, and the roadway network in
the site vicinity shall be determined and displayed on a graphic(s) in the final report. To determine
AM and PM existing traffic volumes, machine counts and/or manual counts shall be conducted
during a three -hour period of the morning, between approximately 6:00 AM to 9:00 AM of an
average or typical weekday, and also between approximately 3:00 PM to 6:00 PM, on an average
or typical weekday. Peak hour counts may be required on Saturday and/or Sunday, depending on
the proposed land use. All AM and PM peak hour counts shall be recorded and summarized in
fifteen - minute increments, and be included in the Appendix of the final report. Manual counts
shall include vehicle classifications, i.e. passenger cars, single -unit, multi -unit trucks and buses.
Traffic counts shall show both entering and exiting traffic at the proposed access points (if
existing), in addition to turning and through traffic movements at critical intersections.
TRIP GENERATION RATES AND VOLUMES: Trip generation rates and volumes for each
type of proposed land use shall be determined for the AM and PM peak hours, and total daily
volumes may be required on Saturday and/or Sunday, depending on the proposed land use. The
trip generation rates shall be calculated from the latest data available contained in the Institute of
Transportation Engineer's "Trip Generation Manual ". If trip generation rates for a specific land
use are not available from the "Trip Generation Manual", the United City of Yorkville shall
approve the substitute rates. I
SITE- GENERATED TRIP DISTRIBUTION & ASSIGNMENT: The most logically traveled I

purposes. The directional distribution of site - generated traffic approaching and departing the
development should be shown in both graphic and tabular form. All assumptions used in the
determination of distribution and assignment shall be clearly stated.
EXISTING. PLUS SITE - GENERATED TRAFFIC VOLUMES: Existing, plus site - generated
traffic volumes for the AM and PM peak hours, and total daily traffic for access drives,
intersections, and the roadway network in the site vicinity shall be determined and displayed on a
graphic(s) in the final report. Traffic volumes shall show both entering and exiting traffic at the
proposed access points, in addition to turning and through traffic movements at critical
intersections.
FUTURE TRAFFIC (EXISTING. PLUS SITE - GENERATED) VOLUMES: Future traffic
(existing, plus site - generated traffic volumes) for the AM and PM peak hours, and the total daily
traffic for access drives, intersections, and roadway network in the site vicinity shall be determined
and displayed on a graphic(s) in the final report. Projected increases in the external (non site -
related) roadway traffic must also be determined. The selection of a horizon year for which traffic
operation conditions are to be characterized may be considered as the date full build -out and
occupancy is achieved. If the project is a large multi -phased development in which several stages
of development activity are planned, a number of horizon years may be required, that correspond
to the bringing on line of major development phases. Horizon dates should be times to coincide
with major stages of the overall project, or to coincide with increments of area transportation
system improvements.

evaluation of design and operation alternatives of the access driveways and influenced
intersections. The capacity analysis shall be in accordance with the techniques described in the
most recent edition of the Transportation Research Board's "Highway Capacity Manual", Special
Report 209.
SIGNALIZATION WARRANTS: If it is anticipated that the development's driveway(s) or
existing external non - signalized intersections will satisfy signalization warrants, a warrant analysis
shall be conducted, using the projected volumes determined from the trip- generation. The results
of such an analysis shall be tabulated in the traffic impact study.
CONCLUSIONS AND RECOMMENDATIONS: Clear and concise descriptions of the findings
shall be presented in the final report. These findings shall include all recommended improvements
for access facilities, internal roadways and intersections, and external roadway and intersection

Section 1.1 Statutory Authority
These regulations are enacted pursuant to the police powers granted to this City by The Illinois Municipal Code.
Section 1.2 Findings
The United City of Yorkville finds that Isolated Waters of Yorkville and Waters of the U.S. for the Fox River,
Aux Sable, Blackberry Creek, and Rob Roy watersheds including their ,tributaries, are indispensable and fragile
resources that provide many public benefits including maintenance of surface and groundwater quality through
nutrient cycling and sediment trapping as well as flood and storm water runoff control through temporary water
storage, slow release, and groundwater recharge. In addition, Isolated Waters of Yorkville provide open space;
passive outdoor recreation opportunities; fish and wildlife habitat for many forms of wildlife including
migratory waterfowl, and rare, threatened or endangered wildlife and plant species; and pollution treatment via
biological and chemical oxidation processes.
Preservation of the remaining Isolated Waters of Yorkville and Waters of the U.S. in a natural condition shall be
and is necessary to maintain hydrological, economic, recreational, and aesthetic natural resource values for
existing and future residents of the United City of Yorkville, and therefore the City Council declares a policy of
no net loss of Isolated Waters of Yorkville and Waters of the U.S. Furthermore the City Council declares a I
long -term goal of net gain of Isolated Waters of Yorkville and Waters of the U.S. to be accomplished through I
mitigation these regulations.
Section 1.3 Objectives
The principal objective of these regulations is the protection, preservation, replacement, proper maintenance,
restoration, and use in accordance with the character, adaptability, and stability of the Isolated Waters of
Yorkville in order to prevent their pollution or contamination; minimize their disturbance, and prevent damage
from erosion, siltation, and flooding. Other objectives of these regulations include:
• Preserve and enhance the natural hydrologic and hydraulic functions and natural characteristics of
i
watercourses and wetlands to protect water quality, aquatic habitats, provide recreational and aesthetic
benefits, and enhance community and economic development.
• Maintain and enhance the special aquatic resources of the City.
• Protect environmentally sensitive areas from deterioration or destruction by private and public actions.
• Protect and improve surface water quality and promote best management practices of surface water
runoff prior to entering lakes, ponds, wetlands, streams, and rivers.
• Require planning for development to carry out water resource management including the protection of
natural areas such as remnant woodland and prairie habitats, wetlands, waterways, steep topography,
and highly erodible soils, in order to reduce potential impacts, or creation of unstable conditions that
may promote erosion and degradation of ground and surface water quality.
• Coordination of and support for the enforcement of applicable federal, state, and county statutes,
ordinances, and regulations pertaining to Waters of the U.S., floodplain regulations, and soil erosion
and sediment control.
• Establishment of standards and procedures for the review and regulation of the use of Isolated Waters
of Yorkville.
• A procedure for appealing decisions.

Floristic inventory is a record of all existing vegetation within a defined project area. This includes all woody
(trees and shrubs) as well as herbaceous plants, i.e., wildflowers and grasses.
Floristic Quality Assessment (FQA) refers to a method of assessing landscapes based upon the existing
vegetation. A useful method for determining the floristic quality of an area is through an analysis of the
conservatism and diversity of species appearing in a plant inventory. Refer to floristic quality index and Mean
C for further definition of terms.
Floristic Quality Index (FQI) is a statistic derived by multiplying Mean C by the square root of the number of
species inventoried. This parameter is correlated to the diversity and conservatism of native plant species
present within a plant community as defined in Plants of the Chicago Region, 4 Ed. (Swink and Wilhelm,
1994).
Forested wetland is an area dominated by wetland plants that have a predominance of woody vegetation with
periodic flooding. Two types of forested wetlands exist as defined by the Illinois Department of Natural
Resources. The most common are areas adjacent to rivers and swamps with silver maple, sycamore, and
cottonwood as predominant species and rotting logs littering the forest floor. Drier forested wetlands experience
occasional flooding with oaks, elms and hickory as predominant species with a variety of annual and perennial
plants that cover the forest floor.
Functional assessment is an assessment of a wetland's flood storage, water quality, wildlife habitat, and other
beneficial functions.
Groundwater is that water that is located within soil or rock below the surface of the earth.
High Quality Aquatic Resources (HQAR) means aquatic areas considered to be regionally critical due to their
uniqueness, scarcity, and/or value, and other wetlands considered to perform functions important to the public
interest, as defined in 33 CFR Part 320.4(b) (2). These resources include ephemeral pools, fens, forested
wetlands, sedge meadows, seeps, streams rated Class A or B in the Illinois Biological Stream Characterization
study, streamside marshes, wet prairies, wetlands that support Federal or Illinois endangered or threatened
i
species, and wetlands with a native floristic quality index (FQI) of 25 or greater and a native Mean C value of

Hydrologically disturbed is an area where the land surface has been cleared, grubbed, compacted, or otherwise
modified to alter stormwater runoff, volumes, rates, flow direction, or inundation duration.
Index of Biotic Integrity (IBn is a biological stream characterization rating system that assesses the quality of
a stream from the sum of 12 metrics based on fish population composition, quality, and abundance. The IBI
value can range from 12 to 60 (low to high rating).
Isolated Waters of Yorkville means all wetlands; waterbodies such as ponds, lakes, streams, - including
ephemeral and intermittent streams, and roadside ditches (that meet the criteria of wetland habitat as defined in
the USACE 1987 Wetlands Delineation Manual and with a drainage area greater than 20- acres); farmed
wetlands; and detention basins (that meet the criteria of wetland habitat); and are not under U.S. Army Corps of
Engineers jurisdiction and are located within the limits of the United City of Yorkville or with any area under

B. Compensatory wetland mitigation created to meet these regulations or Section 404 of the Clean
Water Act is not excluded.
Intermittent stream is a stream whose bed intersects the groundwater table for only a portion of the year on
average or any stream that flows continuously for at least one month out of the year, but not the entire year.
Lake is a body of water two or more acres in size that retains water throughout the year.
Linear Waters of the U.S. means wetlands along creeks, streams,` - rivers, ponds, lakes, or impoundments that
are hydraulically connected to jurisdictional Waters of the U.S.
Mean C is the average coefficient of conservatism for a site. The concept of "conservatism" refers to the
fundamental character of native plant species to display varying degrees of tolerance to disturbance, as well as
varying degrees of fidelity to specific habitat integrity. As a result, each native species can be assigned a
coefficient of conservatism (C value) ranging from 0 to 10, "weedy to conservative," reflecting its disposition
within a defined geographic region. i
Mitigation is the measures that are taken to eliminate or minimize negative direct or indirect impacts caused
from development activities, such as impact to Isolated Waters of Yorkville, by replacement of the resource.
Native Mean Wetness is the wetness value (W) designated to each species. This value defines the estimated
probability of each species occurring in a wetland. Plants are designated as Obligate Wetland (0131,= -5),
Facultative Wetland (FACW = -3), Facultative (FAC =O), Facultative Upland (FACU =3), and Obligate Upland
(UPL =S).
Natural area is a landscape with a sufficient level of intact habitat structure and plant species composition to
resemble a pre - settlement landscape, e.g., prairie, oak savanna, and other landscapes native to Kendall County.

remain undeveloped for preservation purposes. {
Pond is a body of water less than two acres in size that retains a normal water level year - round.
Qualified professional is a person trained in one or more of the disciplines of biology, geology, soil science,
engineering, or hydrology whose training and experience ensure a competent analysis and assessment of stream,
lake, pond, and wetland conditions and impacts.
Relative Importance Value (RIV). The RIV for each species is calculated by summing relative frequency and
relative cover and dividing by 2. The RIV is calculated from data collected during the transect inventory.
Roadside ditches are drainage ditches created for the purpose of providing roadway drainage.

infiltration capacity of the soils for that basin.
Seep is a wetland, herbaceous or wooded, with saturated soil or inundation resulting from the diffuse flow of
groundwater to the surface stratum.
Site is all of the land contemplated to be part of a coordinated development of one or more parcels.

FOR WATER QUALITY & STORMWATER MANAGEMENT BENEFITS AND PERMIT PROVISIONS
Section 3.1 General Standards
These regulations are for the region of the United City of Yorkville and based on the ecological characteristics
of this region.
Section 3.1.1 Buffer Requirements
1. Buffer areas shall be required for all areas defined as either Is Waters of Yorkville or Waters of the !
U.S. except for areas that meet a Category III definition. Isolated Waters of Yorkville are under the I
jurisdictional authority of the United City of Yorkville and these regulations and are defined in Section 2.1
of these regulations. Waters of the U.S. as defined in Section 2.1 of these regulations refers to areas that
are under the jurisdictional authority and regulated by the United States Army Corps of Engineers
(USACE).
2. Buffer areas are divided into two types, linear buffers and water body buffers. The following buffer
requirements shall be met for all proposed development projects and provided for all wetlands except for
areas meeting the definition of a Category III wetland (roadside ditches and manmade stormwater
management facility, refer to Section 2.1). For areas under the jurisdiction of the USACE, the most I
stringent buffer requirements shall apply.
1) Linear buffers shall be designated along both sides of the channel. The buffer width shall be
determined as follows:
a. All channels except those determined to be High Quality Aquatic Resource (HQAR) shall be
provided a minimum buffer of 30 feet. Also, five (5) additional feet of buffer shall be
provided for each percent of buffer slope towards the channel that is greater than 10% up to a
maximum of a 100 -foot buffer. For example, a 30 -foot buffer with a 20% slope will require
an additional 50 feet of buffer for a total buffer width of 80 feet. The buffer slope shall be
calculated as the average slope from the landward edge of the buffer to the top of bank of the
channel or highest point in elevation immediately adjacent to the "waters ", be it natural or
artificial.
b. Streams rated Class A or B in the Illinois Biological Stream Characterization study or with
an Index of Biotic Integrity (IBI) greater than 40 shall have a minim buffer width of 100
feet on each side of the channel. (Initial IBI based on [EPA Illinois Water Quality Report.
A site - specific IBI assessment may override this report).
c. For streambank stabilization projects, those projects that involve a change in land use shall
apply the minimum 30 foot buffer and up to a maximum of 100 foot buffer criteria. If the
project does not involve a change in land use, then a 10 foot buffer shall be required adjacent
to all streambank stabilization work.
2) Buffers shall encompass all wetlands greater than '' /a acre and determined not to be a high quality
aquatic resource (HQAR). The buffer width shall be determined as follows:
a. For all wetlands with a total surface area greater than one quarter (1/4) acre with floristic
quality values of native Mean C < 2.8 and/or native FQI < 20, and determined not to be a
HQAR, a minimum buffer width of 30 feet shall be established. Also, five (5) additional
feet of buffer shall be required for each percent of buffer slope towards the wetland that is
greater than 10% up to a maximum of a 100 foot buffer.
b. For all wetlands with a total surface area greater than one quarter (1/4) acre with floristic
quality values of native Mean C > 2.8 and native FQI > 20, and determined not to be a
HQAR, a minimum buffer width of 50 feet shall be established. Also, five (5) additional
feet of buffer shall be required for each percent of buffer slope towards the wetland that is
Article 3 10
UNITED CITY OF YORKVILLE WETLAND PROTECTION REGULATION WETLAND PROTECTION STANDARDS
FOR WATER QUALITY & STORMWATER MANAGEMENT BENEFITS AND PERMIT PROVISIONS
greater than 10% up to a maximum of a 100 foot buffer. (Refer to Section 3.1.1 2(1)a for
example of calculating additional buffer based on average slope towards the wetland)
c. For all wetlands regardless of size that meet the definition of a HQAR (ephemeral pools,
fens, forested wetlands, sedge meadows, seeps, streamside marshes, wet prairies, wetlands
supporting Federal or Illinois endangered or threatened species, and wetlands with a native
floristic quality index (FQI) of 25 or greater and a native Mean C value of 3.2 or greater),
shall have a minimum buffer width of 100 feet.
3. Buffer areas for all linear Isolated Waters of Yorkville or Waters of the U.S., shall extend from the top of
bank. The buffer area for non - linear Isolated Waters of Yorkville or Waters of the U.S., except wetlands,
shall extend from waters edge at normal water level. The buffer area for wetlands shall extend from the
edge of the approved delineated wetland boundary. A site may contain buffer that originates from Isolated
Waters of Yorkville or Waters of the U.S. on another property..
4. Buffer averaging shall be permitted, at the discretion of the Staff, but at no time shall the buffer width at
any given point be less than 50% of the required width, and provided that the total buffer area required is
achieved. A reduction of buffer width shall not occur for any portion where the adjacent landscape has a
slope towards the wetland, equal to or greater than 3:1; except if an existing barrier, e.g. earthen berm, is in
place that slows and/or contains the surface water runoff toward the wetland. In such case, the existing
barrier shall remain in place and be incorporated into the design. The barrier shall be maintained as part of
the required buffer area.
5. The requirement of buffers is strictly for preservation measures of wetlands and shall not constitute
enhancement measures of existing wetlands for any mitigation requirements of said development.
6. Buffers shall be established using appropriate deep- rooted vegetation, protected from direct and indirect
disturbance, and shall be appropriately managed and maintained according to an approved plan as provided
under Section 3.2.4. Buffers shall typically consist of native vegetation unless otherwise approved by Staff.
7. If a buffer area is disturbed by permitted activities during construction, the buffer area shall be stabilized
following the provisions of the United City of Yorkville's Soil Erosion and Sediment Control Ordinance
and planted with appropriate vegetation as stated above.
8. Access through buffer areas shall be provided, when necessary, for maintenance purposes. Unless
otherwise dedicated for a public purpose or to a public entity, buffer areas shall remain private property and
shall not be generally accessible for the public.
9. Preservation of buffer areas shall be provided by deed or plat restrictions. Only public or quasi - public
property, e.g. municipal, common Homeowners Association (HOA) lot lines shall be allowed within the
limits of the buffer areas.
10. Features of a stormwater management system approved by Staff may be allowed within the buffer area
provided it is a naturalized detention basin that consists of a natural design shape as well as native plant
communities, or other naturalized stormwater management feature and provided there is no direct discharge
to the wetland habitat. A stormwater management feature shall be located, at a minimum, fifteen (15) feet
from the edge of wetland, or top of bank for linear buffers. Discharge from the stormwater management
feature shall be directed to the outside edge of the required buffer width to allow the full width of the buffer
to be used for energy dissipation and water ' quality protection. Staff shall review and approve, as
appropriate, well - designed stormwater management systems within the buffer area on a project by project
basis.
11. Stormwater discharges that enter a buffer shall have appropriate energy dissipation measures to prevent
erosion and scour. These can include, but are not limited to; level spreaders, riprap, drop catch basins
(plunge pools), or other measures as deemed appropriate by Staff.
Article 3 11
UNITED CITY OF YORKVILLE WETLAND PROTECTION REGULATION WETLAND PROTECTION STANDARDS
FOR WATER QUALITY & STORMWATER MANAGEMENT BENEFITS AND PERMIT PROVISIONS
12. All buffer areas shall be maintained free from development including disturbance of soil, dumping or
filling, erection of structures, and placement of impervious surfaces except as follows:
1) A buffer area may be used for passive recreation (e.g., bird watching, walking, jogging,
bicycling, and picnicking) and it may contain pedestrian or bicycle trails, provided that the
created path is no wider than ten (10) feet. Paths or trails, excluding a mowed grass path, shall be
located, at a minimum, fifteen (15) feet from the edge of wetland or stream. If the path leads to a
wetland, it must be designed to prevent erosion.
2) Paved surfaces including trails may not occupy more than 15% of the total width of the required
buffer. If a paved path or trail width is greater than 15% of the buffer width, then the path width
shall be added to the overall buffer width. (For example, an eight (8) foot paved trail is being
installed within a 30 -foot buffer. The paved trail width is greater than 15% of the buffer width
(approximately 27 %). Therefore, an additional eight-(8) feet — the width of the path — shall be
added to the overall required buffer width for a total buffer width of 38 feet). Where grass "mow
strips" are desired adjacent to paths they shall be no wider than two (2) feet on each side of the
path. An eight (8) foot high clearance zone must be provided, no plant material can overhang the
path within this area.
3) Limestone paths, as pervious surfacing, do not require additional buffer width but still require a
two (2) foot clear zone on each side of the path. Limestone paths cannot be located near a habitat
that can be affected by a potential change in soil pH. The path shall not erode into the natural
area. Special precautions to eliminate this may require subdrainage, edging, compaction, etc.
4) Utility maintenance and maintenance of drainage facilities and drainage easements shall be
allowed provided the maintenance activity meets all other federal, state, and local regulations.
Section 3.1.2 Wetland Hydrology Protection
1. Any development that may reasonably be expected to impact the recharge zone of a fen, seep, or other
groundwater -driven wetland with vegetation characteristic of these habitats requires a higher level of
protection. Due to the uniqueness and fragility of these habitats, the developer of any proposed
development within potential recharge zones shall to the extent possible identify, maintain, and protect said
recharge zones. Staff shall evaluate and determine if additional documentation is required on a case by
case basis.
Section 3.1.3 Stormwater Management within Isolated Waters of Yorkville
1. Stormwater management facilities shall only be allowed in areas that meet the definition of farmed
wetlands or Isolated Waters of Yorkville that contain at a minimum, vegetative cover of > 75% of one or
more of the following species.
• Reed Canary Grass (Phalaris arundinacea).
• Purple Loosestrife (Lythrum salicaria).
• Common Reed (Phragmites australis).
• European or Common Buckthorn (Rhamnus cathartica.).
• Canada Thistle (Cirsium arvenser).
• Narrow- leaved cattail (Typha angustifolia).
• Sandbar willow (Salix interior).
1) The stormwater management facility shall be designed as a naturalized wetland basin that
contains native vegetation communities and does not exceed a 4 -foot bounce for the 100 -year,
24 -hour storm event. Mitigation credit for designed permanent open water area(s) shall not be
granted for more than 20% of the overall required mitigation acreage. At the discretion of Staff,
however, greater than 20% up to a maximum 50% mitigation credit for open water may be
Article 3 12
UNITED CITY OF YORKVILLE WETLAND PROTECTION REGULATION WETLAND PROTECTION STANDARDS
FOR WATER QUALITY & STORMWATER MANAGEMENT BENEFITS AND PERMIT PROVISIONS
applied for mitigation designs that create interspersion of open water with emergent wetland
habitat. The area of the basin as measured between the contours corresponding to one (1) foot
above NWL and two (2) feet below NWL shall be at least equal to the remaining impacted
wetland acreage. The designed naturalized basin shall demonstrate an overall environmental
improvement.
2) A naturalized buffer that contains appropriate native vegetation shall be provided, at a
minimum, up to the High Water Level (HWL).
3) A three (3) year management and monitoring plan shall be provided for the naturalized
stormwater management facility. The management/monitoring plan shall include performance
standards, which identify percent of seeded/planted species to be alive and apparent; vegetative
cover of native , non -weedy species; and floristic quality for each monitoring year, monitoring
methods, prescribed maintenance activities for the -3 -year period, and long -term management
provisions.
1
2. Staff may waive mitigation requirements for wetland impacts from the development of stormwater
management facilities within wetland habitat if the designed naturalized wetland basin meets the above
criteria. If the proposed stormwater management facility does not meet the above criteria, the mitigation
requirements of Article 4 of these regulations shall apply.
Section 3.1.4 Discharge to Isolated Waters of Yorkville or Waters of the U.S.
1. There shall be no direct discharge of stormwater runoff to Isolated Waters of Yorkville or Waters of the
U.S. without pre - treatment. Accepted methods of pre - treatment include, but are not limited to created
wetland detention basins, naturalized swales, biofiltration practices, and other measures that filter and/or
detain runoff. It must be demonstrated that the proposed pre - treatment measure will remove a minimum of
80% total suspended solids (TSS) and prevent increases in water level fluctuations up to and including the
2 -year event within the wetland. All discharges shall be to the wetland buffer. Pre - treatment measures
may be located within the buffer with approval from the Staff. Appropriate energy dissipation measures,
such as level spreaders, shall be provided to prevent erosion and scour.
Section 3.1.5 Protection of Isolated Waters of Yorkville During Development
1. All Isolated Waters of Yorkville designated for preservation shall be protected during development such
that a FQI calculated two years after the commencement of development shall not be more than five (5)
points less than the originally calculated FQI. The re- evaluation of all preserved wetlands shall be
completed during a similar stage of the growing season as was conducted for the original assessment (f30
days). If final build out of all lots contiguous to Isolated Waters of Yorkville has not occurred, the re-
evaluation of all preserved wetlands shall be repeated each year until completion of development. If there
is a decrease in the FQI value for two consecutive years, and/or a > 5 point drop in the FQI value from the
original value, a wetland impact to Isolated Waters of Yorkville shall be assumed, and the mitigation
requirements of Article 4 of these regulations shall apply.
2. The initial re- evaluation data shall be submitted to Staff during the second year after commencement of the
development. All subsequent re- evaluation data shall be provided to Staff on an annual basis until final
build out of the development has occurred.
Section 3.1.6 Maintenance of Stormwater Management Facilities
Dredging of stormwater management facilities that meet the definition of Isolated Waters of Yorkville for the
purpose of periodic maintenance shall be allowed without the issuance of a Wetland Protection Permit given
that the dredging activity will only re- establish the original design depths and measures shall be taken to
preserve any wetland fringe and/or buffer (if applicable). If any disturbance to the wetland fringe is
unavoidable, then the wetland fringe shall be restored with appropriate native vegetation. Dredging frequency

Section 4.1 Unmitigable Wetland Impacts
1. Wetlands of any size identified as having a FQI greater than or equal to 35 or mean C value of 3.5 or
greater shall not be impacted via flooding, excavation, dredging, fill, drainage, or other hydrological
disturbance, vegetation removal (other than for maintenance or restoration purposes) as part of any
development or dumping, or non - permitted discharge of chemicals or other pollutants. The FQI is solely
based on the wetland vegetation. To determine the floristic value of the wetland, buffers and adjacent plant
communities shall not be included in the calculation.
Section 4.2 Wetland Mitigation Requirements
Section 4.2.1 General Mitigation Requirements
1. Mitigation shall be required for all impacts, regardless of size to Category V wetlands.
2. Mitigation shall be required for wetland impacts greater than or equal to '/4 (0.25) acre to Isolated Waters of
Yorkville defined under Category I, Category II, and Category VI wetland impacts.
3. Mitigation shall provide for the replacement of the wetland habitat impacted due to development activities
at the following ratios (creation acreage to wetland impact acreage):
1) A minimum of 1.5:1 for wetland impacts under Category I or II that are not to a HQAR and are
mitigated on -site
2) A minimum of 1:1 for wetland impacts under Category VI and are mitigated on -site.
3) A minimum of 10:1 for wetland impacts that are to a HQAR under Category V and are mitigated
on -site
I
4. Wetland impacts covered under Category III will not require mitigation per se, but at a minimum, shall
replace the water quality functions through 13MP's as approved by Staff.
5. No mitigation is required for Category IV wetland impacts provided the restoration, creation, or
enhancement contributes a net gain of aquatic resource function(s). Category IV wetland impacts,
however, shall be required to provide all Wetland Permit Submittal Requirements, as applicable, following
Section 3.2.4 of these regulations.
6. Wetland mitigation shall be designed wherever possible to restore wetland hydrology to historic hydric
soils that have been drained or dewatered. Grading activities for wetland creation and/or restoration should
be minim ized.
7. Mitigated wetlands shall be designed to optimize hydrologic stability and native species diversity.
Designed permanent open water area(s) shall not constitute more than 20% of the required mitigation
acreage. At the discretion of Staff, however, greater than 20% up to a maximum 50% mitigation credit for
open water may be applied for mitigation designs that create interspersion of open water with emergent
wetland habitat.
8. Any creation of wetlands for required mitigation shall take place only within areas that are not of a remnant
plant community, wetlands, or other natural areas.
9. Enhancement within existing wetlands may be used as part of the mitigation credits, provided that at a
minimum, wetland creation and/or restoration is at a 1:1 ratio, the mitigation creation/restoration is
provided on -site, and the impacted wetland(s) does not meet the definition of HQAR. Mitigation credit for
enhancement measures will be at a 0.25:1 ratio (0.25 acre credit for every 1.0 acre enhanced).

FOR WATER QUALITY & STORMWATER MANAGEMENT BENEFITS REQUIREMENTS
10. All wetland mitigation areas shall be buffered according to the requirements of Section 3.1.1. No buffer is
required for that portion of a wetland mitigation area that is adjacent to an existing preserved wetland.
11. A five -year wetland mitigation irrevocable letter of credit in favor of the City or equivalent security for
110% of mitigation cost following the provisions of Article 10 of these regulations shall be submitted prior
to receipt of the permit.
12. For those impacts that will have a total wetland impact of lesg''tlxan or equal to 1.0 acre and not affect a
HQAR, the fee -in -lieu of mitigation option may be required by the City. Conditions under which the fee -
in -lieu option may be required include, but are not limited to:
1) There are no other on -site or immediately adjacent wetlands that could be expanded.
2) The total size of the impacted wetland is 2.0 acres or less and due to development conditions, the
long -term viability of the wetland is questionable.
In addition, the fee -in -lieu option may be used by the developer for wetland impacts; this will be at the
discretion of Staff and City Council. Fees paid in lieu that are not required by Staff and City Council, shall
be comparable to the cost of mitigation off -site, but within the same watershed as the wetland impact,
including land costs. The mitigation rate shall be 1 '/Z (1.5) times the on -site required mitigation acreage for
calculation of the estimate of probable mitigation cost for non -HQAR sites. The mitigation rate shall be 3.0
times the on -site required mitigation acreage for calculation of the estimate of probable mitigation cost for
HQAR sites. Fees paid in lieu that are required by City Countil with Staff's recommendation shall be
comparable to the cost of on -site mitigation, including land costs.
13. Wetland impacts occurring prior to issuance of a Wetland Permit shall presume the wetland disturbed was a
HQAR and shall require mitigation at a minimum rate of 10:1.

All mitigation shall occur within the limits of the City's jurisdiction. For the off -site mitigation purposes of
these regulations, wetland mitigation shall occur within the same primary watershed (Aux Sable or Fox River)
as the wetland impact, unless there is an available wetland mitigation bank within the sub - watershed
corresponding to the impact (Blackberry, Rob Roy). Mitigation shall use the following hierarchy.
1. On -site wetland mitigation is preferred, but only if the applicant can document that the mitigation can
expand the extent or improve the quality of other existing, undisturbed on -site or immediately adjacent
wetlands or on -site mitigation will create or restore a wetland equal to or greater than 1.5 acres in size. On-
site mitigation shall meet the requirements of Article 4 of these regulations.
2. Off -site wetland mitigation within the same primary watershed as the wetland impact or within an approved
wetland mitigation bank located within the primary watershed when on -site mitigation is not feasible.
Required mitigation acreage shall be the on -site required mitigation acreage. Off -site created or restored
wetland mitigation shall meet the requirements of Article 4 of these regulations,
3. Mitigation as a fee -in -lieu payment option that is not required by the City. The mitigation rate shall be 1
(1.5) times the on -site required mitigation acreage for calculation of the estimate of probable mitigation
cost for non -HQAR sites, 3.0 times for HQAR sites.
4. Off -site wetland mitigation within the same primary watershed as the wetland impact and meets the
requirements of Article 4 of these regulations or within an approved wetland mitigation bank located within

assurance from the owner that the applicant has permission to use the site for mitigation.
Section 4.4 Wetland Mitigation Monitoring Protocol `'''
1. Following the general USACE guidelines, a 5 -year mitigation monitoring period shall be required to assess
the success of the mitigation. The first monitoring year is considered the first full growing season after
planting. In general, if the full mitigation plan including seeding/planting is completed by end of May in a
particular year, that year can be considered the first monitoring year. If installation is not completed until
later in the.growing season, then the first monitoring year will be the next calendar year.
2. Provide a description of a monitoring protocol that meets the following provisions.
1) General Sampling Methods.
a. Monitoring for every year of the required monitoring period shall include two (2)
monitoring events: one in late spring (May — mid -June) and the second during the late
summer period from mid - August to mid - October.
The purpose of the spring visit is a qualitative assessment of the mitigation site,
accomplished through meander search methodology throughout the entire mitigation area,
including the buffer area, and inventories of vegetation across the different plant
communities /zones. Denote any site conditions where land management should be
addressed (e.g., weed control, herbivory impacts, soil erosion, and sedimentation impacts).
The spring site visit shall be documented in a field report as described in Section 4.6.
I
I
b. The second monitoring event shall provide a more detailed qualitative assessment, and
conduct quantitative sampling along transect lines and document site conditions with
photographs that are taken at permanent photo stations.
The general inventory and FQA data shall be compiled and summarized in the annual monitoring
report as described in Section 4.6
2) Transect Sampling Methods.
a. Generally, at least one (1) transect line shall be established within each of the proposed
wetland mitigation areas and within each plant community across the mitigation site,
including one in the buffer area. Transect locations shall be documented so that sampling
can be repeated year to year.
b. A sufficient number of quadrants shall be sampled along each transect line to provide full
representation of the plant community. In general, a minimum often (10) 0.25 square
meter quadrants per transect is sufficient. Quadrant intervals and number will depend on
the size and uniformity of the plant community.
The sampling procedure includes the recording of all plant species within the quadrant and the
assignment of a cover value. For further detail of the sampling method refer to the "Monitoring
Vegetation" chapter in The Tallarass Restoration Handbook: for Drairies. savannas. and
woodlands (Packard, S. and Mutel, C. 2005).
Article 4 22
UNITED CITY OF YORKVILLE WETLAND PROTECTION REGULATION WETLAND IMPACTS AND MITIGATION
FOR WATER QUALITY & STORMWATER MANAGEMENT BENEFITS REQUIREMENTS
From these data, the Mean C, FQI, and relative importance values (RIV) are generated and are
to be compared with results of the previous monitoring events.
3) Additional Monitoring Parameters.
In addition to the FQA method stated above, some projects may require additional monitoring
parameters for the mitigation and/or preserved wetland(s) such as hydrology, wildlife, etc. The
requirements of additional monitoring parameters shalfbe reviewed and required (if any) by
Staff on a project by project basis.
4) Preliminary Wetland Delineation.
A preliminary wetland delineation of the mitigation wetland(s) boundary shall be conducted
during the third (3 rd ) year of monitoring. The extent of developedwetland shall be based on the
prevalence of hydrophytic vegetation. If the delineated wetland acreage deviates negatively,
10% or greater than the required mitigation acreage, the developer shall be required to prepare
and submit a Remedial Action Plan to Staff. Refer to Section 4.7 Mitigation Requirements for
Non- performing Wetlands.
5) Final Wetland Delineation.
1
A final wetland delineation of the mitigation wetland(s) boundary shall be conducted during the
fifth (5 monitoring year.
Section 4.5 Wetland Mitigation Performance Standards
1. Erosion Control — A biodegradable erosion blanket shall be used for areas up to the 2 -year stage and a
temporary cover crop shall be seeded within the wetland mitigation, which includes the buffer area above
the 2 -year stage, within seven (7) calendar days of completion of construction activities. If the developer is
unable to comply with the 7 -day requirement then the developer shall follow the City's Soil Erosion and
Sediment Control Ordinance. Any additional soil and erosion control measures shall be in accordance to
the City's Soil Erosion and Sediment Control Ordinance.
2. Floristic Quality Assessment.
1) General Inventory.
a. By the end of the third full growing season, 30% of the seeded species and 90% of the
plugged species should be present; and native Mean C and native FQI values shall be
greater than or equal to 2.5 and 15, respectively, for each installed plant community.
b. By the end of the fifth full growing season, 40% of the seeded species and 80% of the
plugged species should be present. The native Mean C and FQI values shall be equal to or
greater than 3.2 and 20, respectively, as measured for each plant community type that
comprises the mitigation area, including the native plant community within the buffer area.
The native Mean C and FQI values should increase each successive year after installation.
C. By the end of the fifth full growing season, the native Mean W shall be less than or equal to
zero (0) for each of the wetland communities.
Generally, prior to the fifth monitoring year, the FQA data presented in the annual report
should reflect a positive trend in floristic metrics in order to be confident that the mitigation
shall meet the stated performance standards in the fifth year. If the mean wetness
coefficient is greater than zero (0), this is an indication that wetland conditions are not
developing. If the native Mean C has not increased from the previous year's monitoring
Article 4 23
UNITED CITY OF YORKVILLE WETLAND PROTECTION REGULATION WETLAND IMPACTS AND MITIGATION
FOR WATER QUALITY & STORMWATER MANAGEMENT BENEFITS REQUIREMENTS
results, this is an indication that additional management activities may be required. It is in
the permittee's best interest to take necessary measures early in the project in order to
ensure compliance with the proposed wetland mitigation.
2) Transect Inventory.
a. The RIV of total native plants should increase each.successive year after installation.
Generally, at the transect level there should be a positive trend in the floristic metrics for
the mitigation monitoring period. If such a trend is observed, one can conclude that for a
particular plant community all reasonable measures have been taken to manage that area.
3. General Standards.
1) By the end of the third full growing season, there shall be no area, across the entire mitigation
site, greater than 1 square meter that is devoid of vegetation, as measured by aerial coverage,
unless specified in the approved mitigation plan. Overall aerial coverage must be 90 %, and I
seedlings of at least 50% of all seed species found.
2) By the end of the fifth full growing season, there shall be no area, across the entire mitigation
site, greater than 0.5 square meter that is devoid of vegetation, as measured by aerial coverage,
unless specified in the approved mitigation plan. Overall aerial coverage must be 99 %, and
seedlings of at least 40% of all seed species found.
3) By the end of the fifth full growing season, none of the three most dominant plant species in any
of the communities that comprise the mitigation site, which includes the buffer area, may be non-
native or weedy species including, but not limited to, Reed Canary Grass, Common Reed, I
Kentucky Blue Grass, Purple Loosestrife, Narrow- leaved cattails, Sandbar Willow, Field Thistle,
sweet clover, woody shrubs such as buckthorn, Eurasian honeysuckles, European High Bush
Cranberry, and other non - native, weedy species.
4) By the end of the fifth full growing season, the proposed wetland acreage as depicted in the
approved plan shall have been achieved. The extent, or deficiency of wetland acreage, that has
not been achieved, is the extent to which the developer shall be liable. Refer to Section 4.7
. Mitigation Requirements for Non - performing Wetlands.
5) Should the developer choose to provide additional required mitigation credits via creation,
restoration, or enhancement measures, the developer shall be required at a minimum, to maintain
and monitor the creation, restoration, or enhancement wetland(s) for an additional three (3) years.
Should the developer choose to provide enhancement measures, the developer shall provide
baseline floristic data of the proposed enhancement wetland(s).
6) Additional Proposed Criteria — Depending upon the mitigation plan submitted there may be
additional criteria required to supplement the above standards. These shall be evaluated on a
project by project basis.
Section 4.6 Post Construction Submittal Requirements
1. Submit as-built conditions to Staff for review and approval as identified below.
1) Final Grading — upon completion of final grading but before planting, submit certified as -built
plans with benchmarks that depict elevations in the mitigation area(s), including invert elevations

water, if applicable, shall be specified. Provide a narrative explanation for any deviation from
Article 4 24
UNITED CITY OF YORKVILLE WETLAND PROTECTION REGULATION WETLAND IMPACTS AND MITIGATION
FOR WATER QUALITY & STORMWATER MANAGEMENT BENEFITS REQUIREMENTS
the approved mitigation plan. If the grades are not within 0.2'± of the approved plan, the
permittee may be responsible for taking necessary corrective measures.
2) Vegetation — submit a list of the actual species seeded and planted by scientific and common
names for each community zone, including the quantity of each species installed (seed
weight/acre, number of plugged plants /acre), dates of seeding and/or planting, source of stock,
and the installation method(s). The vegetation as -built submittal shall include the Wetland
Mitigation Plan graphic that demarks the limits of eac zone installed and identifies
any revisions to the planting plan.
2. Monitoring Reports.
1) Field reports shall be prepared and submitted to Staff within four (4) weeks of the spring
monitoring visit. The field report shall include a brief description of existing site conditions and
proposed management activities that should be addressed during the present growing season.
2) Annual monitoring reports shall be prepared and submitted to Staff by December 30 of the
monitoring year. The annual reports shall include the FQA data and discussion of FQA results,
when applicable, discussion of adherence to the appropriate performance standards, narrative of
the general site conditions, identification of management activities that occurred during the
growing season, recommended management activities to occur over the successive 12 -month
period, and photographs from the established photo stations.
The first year monitoring report shall also include a description of the transect line locations as
well as a graphic of the Wetland Mitigation Plan that denotes the location of all established
transect lines and permanent photo stations.
Years 3 and 5 monitoring reports shall include the results of the surveyed wetland delineation
including completed data forms and a graphic that depicts the location of data points.
I
Section 4.7 Mitigation Requirements for Non - performing Wetlands
1. If the Preliminary Wetland Delineation, performed during the third monitoring year, determines that the
delineated wetland acreage deviates negatively, 10% or greater than the required mitigation acreage, the
developer shall be required to prepare and submit a Remedial Action Plan to Staff. The Remedial Action
Plan shall address measures that will be undertaken to resolve the lack of wetland habitat. A Remedial
Action Plan shall be submitted to Staff within sixty (60) days of submitting the preliminary wetland
delineation findings. If the developer fails to comply with the provisions of this section, the City may draw
upon the required performance security following the provisions of Article 10 of these regulations to
remediate the mitigation site conditions.
2. If the Final Wetland Delineation, performed during the fifth monitoring year, determines that the delineated
wetland acreage does not meet the required mitigation wetland acreage, Staff may require an extension of
the 5 -year monitoring period, payment of fee -in -lieu equivalent to the costs associated with the
construction, planting, monitoring and maintenance of the wetland acreage that is lacking, or request other
measures to meet the intention, requirements, and spirit of these regulations. Failure to meet the required
wetland acreage shall be reviewed and measures required on a project by project basis.
3. In addition, if Staff or his/her agent determines that the wetland mitigation does not meet the Wetland
Mitigation Requirements of Section 4.2 and the Wetland Mitigation Performance Standards of Section 4.5,
the developer shall meet with Staff to determine the acceptable means by which the developer shall meet
his/her wetland mitigation obligation(s). Based upon the review and decision of Staff and City Council, the
developer may be required to:
Article 4 25
UNITED CITY OF YORKVILLE WETLAND PROTECTION REGULATION WETLAND IMPACTS AND MITIGATION
FOR WATER QUALITY & STORMWATER MANAGEMENT BENEFITS REQUIREMENTS
1) Continue management and enhancement measures of the mitigation area(s) for a specified period
beyond the 5 -year monitoring for the improvement of vegetative quality and diversity in order to
meet the required performance standards of these regulations.
2) Provide additional mitigation credits through enhancement measures for other existing
wetland(s).
3) Provide funding into the fee -in -lieu program.
4. If Staff and City Council requests that the developer meet his/her mitigation requirements via payment in-
lieu, Staff shall make an estimate of the probable cost of mitigating for the deficiency in performance.
Staff shall have the right to draw on the performance security the amount of funds appropriate to remedy
the wetland mitigation to meet the performance standards, conditions, and wetland protection standards of
these regulations. The remainder of the performance security shall then be released. The amount withheld
for remedy of the mitigation shall be deposited in the fund created under and expended in the manner
described in Article 11.

safe and proper operating condition by the discharger at its own expense. All devices used to
measure stormwater flow and quality shall be calibrated to ensure their accuracy.
i
(e) Any temporary or permanent obstruction to safe and easy access to the facility to be inspected
and/or sampled shall be promptly removed by the operator at the written or oral request of the
City Engineer and shall not be replaced. The costs of clearing such access shall be borne by the
operator. I
(f) Unreasonable delays in allowing the City Engineer access to a permitted facility is a violation of
a storm water discharge permit and of this chapter. A person who is the operator of a facility with
a NPDES permit to discharge storm water associated with industrial activity commits an offense
if the person denies the City Engineer reasonable access to the permitted facility for the purpose
of conducting any activity authorized or required by this chapter.
(g) If the City Engineer has been refused access to any part of the premises from which stormwater is
discharged, and he /she is able to demonstrate probable cause to believe that there may be a
violation, or that there is a need to inspect and /or sample as part of a routine inspection and
sampling program designed to verify compliance with this chapter or any order issued hereunder,
or to protect the overall public health, safety, and welfare of the community, then the City
Engineer may seek issuance of a search warrant from any court of competent jurisdiction.
Section 8- 17 -10: Requirement to Prevent, Control and Reduce Storm Water Pollutants by the Use of
Best Management Practices: The City has adopted requirements identifying Best Management
Practices for any activity, operation, or facility which may cause or contribute to pollution or
contamination of storm water, the storm drain system, or waters of the United States. The owner or
operator of a commercial or industrial establishment shall provide, at their own expense, reasonable
protection from accidental discharge of prohibited materials or other wastes into the Municipal
Separate Storm Sewer System or watercourses through the use of these structural and non - structural
facilities meeting Best Management Practices requirements. Any person responsible for a property
or premise, which is, or may be, the source of an illegal discharge, may be required to implement, at
said person's expense, additional structural and non - structural facilities to prevent the further
discharge of pollutants to the Municipal Separate Storm Sewer System. Compliance with all terms
and conditions of a valid NPDES permit authorizing the discharge of storm water associated with
industrial activity, to the extent practicable, shall be deemed compliance with the provisions of this
section.
8- 17 -I1: Watercourse Protection: Every person owning property through which a watercourse
passes, or such person's lessee, shall keep and maintain that part of the watercourse within the
property free of trash, debris, excessive vegetation, and other obstacles that would pollute,
contaminate, or significantly retard the flow of water through the watercourse. In addition, the owner
or lessee shall maintain existing privately owned structures within or adjacent to a watercourse, so
that such structures will not become a hazard to the use, function, or physical integrity of the
watercourse.
Section 8- 17 -12: Notification of Spills: Any person responsible for a facility or operation, or
responsible for emergency response for a facility or operation has information of any known or
suspected release of materials which are resulting or may result in Illegal Discharges or pollutants
discharging into storm water, the Municipal Separate Storm Sewer System, or water of the United
States said person shall take all necessary steps to ensure the discovery, containment, and cleanup of
such release and immediately notify emergency response agencies of the occurrence via emergency
dispatch services. In the event of a release of non - hazardous materials, said person shall notify the
City in person or by phone or facsimile no later than the next business day. Notifications in person or
by phone shall be confirmed by written notice addressed and mailed to the City within three business
days of the phone notice. If the discharge of prohibited materials emanates from a commercial or
industrial establishment, the owner or operator of such establishment shall also retain an on -site
written record of the discharge and the actions taken to prevent its recurrence. Such records shall be
retained for at least three years.
Section 8- 17 -13: Ultimate Responsibility: The standards set forth herein and promulgated pursuant
to this Chapter are minimum standards; therefore this Chapter does not intend nor imply that
compliance by any person will ensure that there will be no contamination, pollution, nor
unauthorized discharge of pollutants.
Section 8- 17 -14: Enforcement: Whenever the City Engineer finds that a person has violated a
prohibition or failed to meet a requirement of this chapter, the authorized enforcement agency may
order compliance by written notice of violation to the responsible person in accordance with the
requirements of Chapter 14, Title I of this City Code.
The provisions of this ordinance are hereby declared to be severable. If any provision, clause,
sentence, or paragraph of this Ordinance or the application thereof to any person, establishment,
or circumstances shall be held invalid, such invalidity shall not affect the other provisions or
application of this Ordinance.
This Ordinance shall be in full force and effect from and after its passage and approval as
provided by law. I

STORMWATER MANAGEMENT SYSTEM
ANNUAL MAINTENANCE PLAN FOR EXISTING FACILITIES
Purpose and Obiective:
Detention and water quality treatment facilities, storm sewers, swales and native
vegetation/buffer areas define a development's stormwater management system. When land is
altered to build homes and other developments, the natural system of trees and plants is replaced
with impervious surfaces like sidewalks, streets, decks, roofs, driveways, or lawns over highly
compacted soils. As a result more rain water / storm water flows off the land at a faster rate and
less rain water is absorbed into the soil. This can lead to streambank erosion, downstream
flooding and increased concentrations of pollutants. The existing storm water management
system was designed to help slow the rate of runoff from the development and maintain the
quality of the storm water leaving the site.
Inspection Frequency:
Inspection experience will determine the required cleaning frequencies for the components
of the stormwater management system. At a minimum, the attached checklist items should
be inspected annually. Detention ponds (including the outlet control structure and
restrictors) should be inspected on a monthly basis during wet weather conditions from
March to November.
Maintenance Considerations:
Whenever possible, maintenance activities should be performed during the inspection. These
activities should be supplemented by repair / replacement as required. A Registered
Professional Engineer (PE) shall be hired for design resolution of specific items as indicated
on the checklist below.
Cost Considerations:
Frequent maintenance program work execution will lead to less frequent and less costly long-
term maintenance and repair. The attached checklist items may need to be amended based on
inspection experience.
Record Keeninv-:
Separate and distinct records should be maintained by the responsible party for all tasks
performed associated with this plan. The records shall include the dates of maintenance
visits, who performed the inspection, and a description of the work performed.
5.13 Maintenance Plan Template for Existing Facilities 1
Post - Construction Stormwater Management System .
Inspection Checklist "}
The following checklist describes the suggested routine inspection items and recommended
measures to be taken to ensure that the Stormwater Management System functions as
designed. When hiring a PE is the recommended measure, the PE shall inspect, evaluate `
and recommend corrective actions. The General section outlines items that should be taken
into consideration during inspection and maintenance activities. While performing an
overall inspection of your system, please check for the following items.
General -
• Litter and debris shall be controlled.
• Accumulated sediment shall be disposed of properly, along with any wastes generated
during maintenance operations.
• Riprap areas shall be repaired with the addition of new riprap, as necessary, of adequate
size and shape.
• Roads and parking lots shall be swept or vacuumed on a periodic basis.
• Access path to storm water management facilities should be free from obstiuctions
(woodpiles, sheds, vegetation).
• Fences, gates and posts shall be maintained.
• Signs shall be maintained.
f
Storage Facilities (Detention, Retention and Water Quality Treatment Facilities)
Dams and berms
Settlement. If settlement observed, hire a PE.
Breaks or failures. If failure observed, notify the Village immediately and hire a PE.
Erosion. Repair as needed.
Signs of leakage, seepage or wet spots. If observed, hire a PE.
Unwanted growth or vegetation. Remove as needed.
Shorelines
Erosion or rip -rap failures. Repair as needed
Undermining. Stabilize and repair as needed.
Outlet and inlet structure
Obstructions blocking outlet pipe, restrictor, channel or spillway. Remove
obstructions immediately.
Separation of joints. Repair as needed.
Cracks, breaks, or deterioration of concrete. Repair as needed
Scour and erosion at outlet. If observed, repair (consider additional or alternative
stabilization methods).
Condition of trash racks. Remove any collected debris.
5.13 Maintenance Plan Template for Existing Facilities 2
Outlet channel conditions downstream. Stabilize soil or remove obstructions as
needed.
Storage Volume
Facilities shall be inspected to ensure that the constructed volume for detention is
maintained. No sediment, topsoil, or other dumping into the facility shall be
allowed. If a detention facility includes specific locations designed to accumulate
sediment these locations should be dredged every 5 -yrs or when 50% of the volume
has been lost.
Wet ponds lose 0.5 - 1.0% of their volume annually. Dredging is required when
accumulated volume loss reaches 15 %, or approximately every 15 -20 years.
Storm Sewers
System is free draining into collection channels or catch basins. If concerned, clean
or repair.
Catch basins. Remove sediment when more than 50% of basin sump is filled.
Siltation in Culvert. Culverts shall be checked for siltation deposit, clean out as
necessary.
Bridges
Any scouring around wing walls. Stabilize and repair as needed. If concerned, hire
a PE.
Any undennining of footings. Stabilize and repair as needed. If concerned, hire a
PE.
Swales —
All ditches or pipes connecting ponds in series should be checked for debris that
may block flow.
Repair and replace permanent check -dams as necessary.
Verify systems (both drainage ditches and sideyard swales) are maintaining
originally constructed design slope and cross - sectional area. If fill or sediment
contributes to elevation changes in swale, re- grading and re- shaping shall be
performed. Licensed surveyors shall be hired to lay -out and check grades. No
landscaping, earthen fill, gardens, or other obstructions (including sheds and other
structures) shall be allowed in the swales that would impede design drainage flow
patterns.
Vegetated Areas —
Need for planting, reseeding or sodding of native areas. Supplement alternative
native vegetation if a significant portion has not established (50% of the surface
area). Reseed with alternative grass species if original grass cover has not
successfully established.
Need for planting, reseeding or sodding of turf areas. Supplement alternative native
vegetation if a significant portion has not established (75% of the surface area).
5.13 Maintenance Plan Template for Existing Facilities 3
Reseed with alternative grass species if original grass cover has not successfully
established.
Invasive vegetation (refer to the Native Plant Guide for Streams and Stormwater
Facilities in Northeastern Illinois, or hire an environmental or landscape specialist,
or hire an enviromnental or landscape specialist). Remove as necessary.
Wetland Buffers —
Inspect for evidence of erosion or concentrated flows through or around the buffer.
All eroded areas should be repaired, seeded and mulched. A shallow stone trench
should be installed as a level spreader to distribute flows evenly in any area showing
concentrated flows.
All existing undergrowth, forest floor duff layer, and leaf litter must remain
undisturbed except in designated paths or permitted encroachment areas.
No tree cutting is allowed except for normal maintenance of dead, diseased and
damaged trees or; the culling of invasive, noxious or non - native species that are to
be replaced by more desirable and native vegetation.
A buffer inust maintain a dense, complete and vigorous cover of "non- lawn"
vegetation which should not be mowed no more than once a year. Vegetation may
include grass and other herbaceous species as well as shrubs and trees.
Use or maintenance activities within the buffer shall be conducted so as to prevent

STORMWATER MANAGEMENT SYSTEM
MAINTENANCE PLAN FOR NEW FACILITIES
Subject: INSERT DEVELOPMENT NAME HERE
SUCH PROPERTY BEING THE REAL PROPERTY NOW DULY PLATTED AS INSERT
DEVELOPMENT NAME HERE, AS SUCH PLAT IS NOW RECORDED AS DOCUMENT
NO. INSERT DOCUMENT NUMBER, IN THE OFFICE OF THE RECORDER OF DEEDS
OF THE COUNTY OF KENDALL, STATE OF ILLINOIS, HEREBY MAKES THE
FOLLOWING DECLARATIONS OF MAINTENANCE RESPONSIBILITIES.
Responsibilities
Adequate provisions for maintenance of the stormwater system are an essential aspect of
long -term drainage performance. Responsibility for the overall maintenance shall rest with
the insert responsible party name "here. '
Purpose and Obiective:
Detention and water quality treatment facilities, storm sewers, swales and native
vegetation /buffer areas define a development's stormwater management system. When land is
altered to build homes and other developments, the natural system of trees and plants is replaced
with impervious surfaces like sidewalks, streets, decks, roofs, driveways, or lawns over highly
compacted soils. As a result more rain water / storm water flows off the land at a faster rate and
less rain water is absorbed into the soil. This can lead to streambank erosion, downstream
flooding and increased concentrations of pollutants. The storm water management system was
designed to help slow the rate of runoff from the development and improve the quality of the
storm water leaving the site.
Interpretation as to Requirements Under This Maintenance Plan:
The requirement for this Maintenance Plan is generated by the City of Yorkville Ordinance
2009 -78. The interpretation of the maintenance requirements set forth in this Maintenance
Plan shall be interpreted on the basis of the intent and requirements of said Ordinance.
Inspection Frequency:
Inspection experience will determine the required cleaning fiequencies for the components
of the stormwater management system. At a minimum, the attached checklist items should
be inspected annually. Detention ponds (including the outlet control structure and
restrictors) should be inspected on a monthly basis during wet weather conditions fiom
March to November.
5.14 Maintenance Plan Template for New Facilities 1
Maintenance Considerations:
Whenever possible, maintenance activities should be performed during the inspection. These
activities should be supplemented by repair / replacement as required. A Registered
Professional Engineer (PE) shall be hired for design resolution of specific items as indicated
on the checklist below.
Cost Considerations:
Frequent maintenance program work execution will lead to less fiequent and less costly long -
term maintenance and repair. The attached checklist items may need to be amended based on
experience recorded over the initial period of occupancy of the development.
Record Keeping:
Separate and distinct records shall be maintained by the responsible party for all tasks
performed associated with this plan. The records shall include the dates of maintenance
visits, who performed the inspection, and a description of the work performed.

Post- Construction Stormwater Management System
Inspection Checklist
The following checklist describes the suggested routine inspection items and recommended
measures to be taken to ensure that the Stormwater Management System functions as
designed. When hiring a PE is the recommended measure, the PE shall inspect, evaluate
and recommend corrective actions. The General section outlines items that should be taken
into consideration during inspection and maintenance activities. While performing an
overall inspection of your system, please check for the following items.
General -
• Litter and debris shall be controlled.
• Accumulated sediment shall be disposed of properly, along with any wastes generated
during maintenance operations.
• Riprap areas shall be repaired with the addition of new riprap, as necessary, of adequate
size and shape.
• Roads and parking lots shall be swept or vacuumed on a periodic basis.
• Access path to storm water management facilities should be free from obstructions
(woodpiles, sheds, vegetation).
• Fences, gates and posts shall be maintained.
• Signs shall be maintained.
Dams and berms
Settlement. If settlement observed, hire a PE.
Breaks or failures. If failure observed, notify the Village immediately and hire a PE.
Erosion. Repair as needed.
Signs of leakage, seepage or wet spots. If observed, hire a PE.
Unwanted growth or vegetation. Remove as needed.
Shorelines
Erosion or rip -rap failures. Repair as needed
Undermining. Stabilize and repair as needed.
Outlet and inlet structure
Obstructions blocking outlet pipe, restrictor, channel or spillway. Remove
obstructions immediately.
Separation of joints. Repair as needed.
Cracks, breaks, or deterioration of concrete. Repair as needed
Scour and erosion at outlet. If observed, repair (consider additional or alternative
stabilization methods).
Condition of trash racks. Remove any collected debris.
Outlet channel conditions downstream. Stabilize soil or remove obstructions as
needed.
5.14 Maintenance Plan Template for New Facilities 3
Storage Volume
Facilities shall be inspected to ensure that the constructed volume for detention is
maintained. No sediment, topsoil, or other dumping into the facility shall be
allowed. If a detention facility includes specific locations designed to accumulate
sediment these locations should be dredged every 5 -yrs or when 50% of the volume
has been lost.
Wet ponds lose 0.5 - 1.0% of their volume annually. Dredging is required when
accumulated volume loss reaches 15 %, or approximately every 15 -20 years.
Storm Sewers
System is free draining into collection channels or catch basins. Clean and/or repair
as necessary. -
Catch basins. Remove sediment when more than 50% of basin sump is filled.
Siltation in Culvert. Culverts shall be checked for siltation deposit, clean out as f
necessary.
i
Bridges
Any scouring around wing walls. Stabilize and repair as needed. If concerned, hire
a PE.
Any undermining of footings. Stabilize and repair as needed. If concerned, hire a
PE.
Swales —
All ditches or pipes connecting ponds in series should be checked for debris that
may block flow.
Repair and replace pernianent check -dams as necessary.
Verify systems (both drainage ditches and sideyard swales) are maintaining
originally constructed design slope and cross - sectional area. If fill or sediment
contributes to elevation changes in swale, re- grading and re- shaping shall be
performed. Licensed surveyors shall be hired to lay -out and check grades. No
landscaping, earthen fill, gardens, or other obstructions (including sheds and other
structures) shall be allowed in the swales that would impede design drainage flow
patterns.
Vegetated Areas —
Need for planting, reseeding or sodding of native areas. Supplement alternative
native vegetation if a significant portion has not established (50% of the surface
area). Reseed with alternative grass species if original grass cover has not
successfully established.
Need for planting, reseeding or sodding of turf areas. Supplement alternative native
vegetation if a significant portion has not established (75% of the surface area).
Reseed with alternative grass species if original grass cover has not successfully
established.
5.14 Maintenance Plan Template for New Facilities 4
Invasive vegetation (refer to the Native Plant Guide for Streams and Stonnwater
Facilities in Northeastern Illinois, or hire an environmental or landscape specialist).
Remove as necessary.
Wetland Buffers —
Inspect for evidence of erosion or concentrated flows through or around the buffer.
All eroded areas should be repaired, seeded and mulched. A shallow stone trench
should be installed as a level spreader to distribute flows evenly in any area showing
concentrated flows.
All existing undergrowth, forest floor duff layer, and leaf litter must remain
undisturbed except in designated paths or permitted encroachment areas.
No tree cutting is allowed except for normal maintenance of dead, diseased and
damaged trees or; the culling of invasive, noxious. or non - native species that are to
be replaced by more desirable and native vegetation.
A buffer must maintain a dense, complete and vigorous cover of "non- lawn"
vegetation which should not be mowed more than once a year. Vegetation may
include grass and other herbaceous species as well as shrubs and trees.
Use or maintenance activities within the buffer shall be conducted so as to prevent
damage to vegetation and exposure of soil.

responsible for ensuring that a Stormwater Outfall Inspection Form has been completely
and correctly filled out and that all data and remarks are legible.
Section 1: Background Data
Sub - watershed: The receiving water from the stormwater outfall inventory to be entered
here.
i Outfall ID: Enter the outfall identification number from the stormwater outfall inventory.
Date To avoid confusion, dates are be written in the following manner: DAY MONTH
YEAR. For example, 10 MARCH 2007.
Time Military time (24 -hour clock) to be used (for example, 8:30 a.m. would be written
y as 0830; likewise, 1:30 p.m. would be written as 1,330).
,i.
R
Temperature: A concise description of the weather conditions at the time of the i
screening is to be recorded (for example, Clear, 75o F).
I
Inspector: The name(s) of the field personnel.
Previous 48 Hours Precipitation: The total amount of precipitation during the 48 hours
preceding the inspection is to be noted (for example, none -72 Hours or 0 " =4 days). If the
total precipitation is not known, it is appropriate to enter a qualitative assessment if the
precipitation was minor. For example, Drizzle -36 Hours if appropriate. If the
precipitation amount was significant, actual precipitation totals is obtained from a local
rain gage, if available.
Photo's taken (Yes/No): Photographs are to be taken with a camera that superimposes a
date and time on the film. The date and time should correspond to the date and time
recorded on the data form.

5.18 Storm Water Outfall Inspection Form Instructions
Section 2: Outfall Description
Tvpe of Outfall: Storm Sewer (Closed Pipe) or Open Drainage (Swale /Ditch):
First check if the outfall is either from a Closed Pipe or Open Drainage. Then complete
the following row to describe outfall characteristics.
Section 3: Physical Indicators
Indicators: Complete rows describing outfall characteristics ( Outfall Damage,
Deposits /Stains, Abnormal Vegetation, Poor pool quality, Pipe algae /growth). This
section is filled out regardless of current flow conditions. No flow during the time of the
inspection, does not rule out the potential of illicit discharges. _ Corroding or stained
pipes, dead or absence of vegetation, are potential indicators of illicit discharges from
direct or indirect (i.e. dumping) sources.
Likelihood: After inspecting the physical conditions of the outfall, the likelihood of an
illicit discharge is assessed.
Flow Present (Yes/No): A Yes or No is entered here to indicate the presence or absence
of dry- weather flow. If the outfall is submerged or inaccessible, "See Notes" is entered
and an explanation provided in the "Notes" section.
Flow Description: A description of the quantity of the dry- weather flow is provided.
Refer to Figure 6 of the SMPP.
r
Flow Chart Procedure:
• If No is entered in the "Flow Present" block and no non - flowing physical indicators
appear present the inspection can be closed, skip to Section 7 of the form.
• If No is entered in the "Flow Present" block but indicators appear present, place the
outfall on the follow -up inspection log, then the current inspection can be closed, skip
to Section 7 of the form.
• If Yes is entered in the "Flow Present" block (regardless of the presence of non -
flowing physical indicators), complete remainder of Section and proceed to Section 4.
Section 4: Physical Indicators (Flowing Outfalls Only)
Complete rows describing outfall characteristics (Odor, Color, Turbidity, and Floatables).
This section is filled out for flowing outfalls only.
Odor: The presence of an odor is to be assessed by fanning the hand toward the nose
over a wide -mouth container of the sample, keeping the sample about 6 to 8 inches from
the face. Be careful not to be distracted by odors in the air. Provide a description of the
odor, if present.
5.18 Storm Water Outfall Inspection Form Instructions
Color The presence of color in the discharge is to be assessed by filling a clean glass
sample container with a portion of the grab sample and comparing the sample with a
color chart, if color is present. If a color chart is used, the number corresponding to the
color matching the sample is to be entered in this blank. Color is not assessed by looking
into the discharge. Refer to Table 3 of the SMPP.
Turbidity "clarity ": Turbidity is a measure of the clarity of water. Turbidity may be
caused by many factors, including suspended matter such as clay, silt, or finely divided
organic and inorganic matter. Turbidity is a measure of the optical properties that cause
light to be scattered and not transmitted through a sample. The presence of turbidity is to
be assessed by comparing the sample to clean glass sample container with colorless
distilled water.
Fooatables: The presence of floating scum, foam, oil sheen, or other materials on the
surface of the discharge are to be noted. Describe of any floatables present that are
attributable to discharges from the outfall. Do not include trash originating from areas
adjacent to the outfall in this observation.
Likelihood: After inspecting the physical conditions of the outfall discharge, the
likelihood of an illicit discharge is assessed. If flowing physical indicators are present the
tracing procedure are immediately implemented by one of the field crew. The second
member of the field crew continues with the inspection by performing the on -site testing
in Section 5.
Flow Chart Procedure:
I
• If flowing physical indicators are present the tracing procedure is immediately
implemented by one of the field crew. The second member of the field crew continues
with the inspection by performing the on -site testing in Section 5.
• If flowing physical indicators do not suggest an illicit discharge continue with the
inspection by performing the on -site testing in Section 5.
Section 5: On -Site Sampling /Testing (Flowing Outfalls Only)
Parameters: Test strip or kit chemical analyses are conducted for the following
parameters:
• pH, test strip,
• Color, color chart,
• Chlorine, test strip,
• Copper, test strip,
• Ammonia, test strip,
• Phenols, test kit, and
• Detergents, test kit.
5.18 Storm Water Outfall Inspection Form Instructions
Testing is done by either a test strip or test kit as applicable (refer to the equipment
column). The results are compared with the "acceptable range" and the "within range"
column is filled out with a Yes or No. Note that the Temperature, Alkalinity and
Hardness are determined although these results do not need to be compared with an
"acceptable range ". These values are used to assist in determining the source of the illicit
discharge during the tracing procedure.
Sampling Location: A description of the actual sampling location is to be recorded (for
example, at end of outfall pipe). If the outfall is submerged or is inaccessible for
sampling, an upstream sampling location may be required. A description of any
upstream sampling locations is recorded here. Grab samples are collected from the
middle, both vertically and horizontally, of the dry- weather flow discharge in a critically
cleaned glass container. Samples can be collected by manually dipping a sample
container into the flow.
i
Sampling Procedures: Use the following procedures for all test kit analyses:
1. Take a grab sample and swirl to ensure that the sample is well mixed.
2. Rinse the sample cup (25ml) twice with distilled water. Next, rinse the sample
cup twice with water from the grab sample.
3. Fill the sample cup to the 25 ml mark, or as required by the instructions for the
test kits. Hold the sample cup at eye level to ensure that measurements are
accurate.
4. Conduct the test kit analyses following the manufacturer's instructions.
5. Dispose of the sample as follows:
• If no chemical or reagents have been added to the sample, the water can be
poured on the ground.
• If aM chemical or reagent is added to the sample, pour the water into a container
marked "Liquid Waste" for proper disposal to a sanitary sewer system at the end
of the day.
6. Rinse the sample cup three times with tap water and dry with a paper towel.
Flow Chart Procedure:
• If any parameter is outside of the "acceptable range" then an illicit discharge has likely
been found. The tracing procedure is immediately implemented by one of the field
crew. Testing can be stopped, and the second member of the field crew continues with
the inspection by completing Section 7.
• If none of the parameters are outside of the acceptable range, proceed to Section 6.
5.18 Storm Water Outfall Inspection Form Instructions
Section 6: Data Collection for Lab Testing
Determine if the Yorkville - Bristol Sanitary District has adequate staff capacity to analyze
the samples.
• If YBSD has adequate staff capacity, collect grab samples and provide them to YBSD.
Note the location of the sample. Label the sample with the outfall ID number.
Proceed to Section 7 while in the field and complete the remainder of Section 6 after
the lab results are available.
• If YBSD does not currently have adequate capacity, determine if Sections 3 or 4 of the
inspection form suggest an illicit discharge.
o If Sections 3 or 4 suggest an illicit discharge contact and outside lab to perform the
testing. Proceed to Section 7 while in the field and complete the remainder of
Section 6 after the lab results are available.
o If Sections 3 or 4 do not suggest an illicit discharge, note the outfall ID number.
Place the outfall on the follow -up inspection log and proceed to Section 7 of the
form. Re- inspect and sample the discharge when YBSD has adequate capacity.
Samtule Location: The location of the sample is noted. Additionally, the sample is
labeled with the outfall ID number. Use the city's sampling procedures. The following
additional items are noted.
1. When you collect any samples you must fill out an Outfall Sampling Report.
The report must document time you arrive on location, take the sample and get to
the plant to drop off the sample. j
o
2. A 500 -m1 glass bottle sample is used to collect the sample. If you are collecting a
sample that has grease 2 -250ml samples taken a glass container are required.
3. If you use the sampling container that is on a rope, it must be washed with soap
and water after every use.
Parameters: Grab samples and lab testing is performed. After lab results are available
enter the results here.
• If any parameter is outside of the "acceptable range" then an illicit discharge has likely
been found. The tracing procedure should be immediately implemented.
• If none of the parameters are outside of the acceptable then the investigation can be
closed.
Section 7: Any Non - Illicit Discharge Concerns
Any problems or unusual features are to be entered here. If the outfall appears to be
potentially impacted by inappropriate discharges, this can be recorded here. This section
is to be completed even if no flow is observed.

Stormwater runoff is precipitation from rain or
snowmelt that flows over the ground. As it flows,
it can pick up debris, chemicals, dirt, and other
pollutants and deposit them into a storm sewer
system or waterbody.
Anything that enters a storm sewer system is
discharged untreated into the waterbodies we
use for swimming, fishing, and providing
drinking water.
Remember:
Only Rain Down the Drain
