District Map and Boundaries
A.Zoning Map. The boundaries of the zoning districts designated in Section 10-3-1 of this chapter are hereby established as
shown on the latest edition of the map entitled “Zoning Map: The United City Of Yorkville”, which said map shall have the
same force and effect as if the zoning map, together with all notations, references and other information shown on the
zoning map, were fully set forth and described in this title.
B.District Boundaries. When uncertainty exists with respect to the boundaries of the various districts shown on the zoning
map, the following rules shall apply:
1.District boundary lines are either the centerlines of railroads, highways, streets, alleys or easements or the boundary
lines of sections, quarter sections, divisions of sections, tracts or lots, or such lines extended or otherwise indicated.
2.In areas not subdivided into lots and blocks, wherever a district is indicated as a strip adjacent to and paralleling a
street or highway, the depth of such strips shall be in accordance with the dimensions shown on the map measured at
right angles from the centerline of the street or highway, and the length of frontage shall be in accordance with
dimensions shown on the map from section, quarter sections or division lines, or centerlines of streets, highways or
railroad rights of way unless otherwise indicated.
3.Where a lot held under single ownership and of record on the effective date hereof is divided by a district boundary
line, the entire lot shall be construed to be within the less restricted district; provided, that this construction shall not
apply if it increases the lot width of the lot by more than twenty-five (25) feet.
Zoning of Streets, Alleys, Public Ways, Waterways, and Railroad Rights-
of-Way
All streets, alleys, public ways, waterways, and railroad rights-of-way, if not otherwise specifically designated, shall be deemed to
be in the same zone as the property immediately abutting upon such alleys, streets, public ways, or waterways and railroad
rights-of-way. Where the centerline of a street, alley, public way, waterway, or railroad right-of-way serves as a district boundary,
the zoning of such areas, unless otherwise specifically designated, shall be deemed to be the same as that of the abutting
property up to such centerline.
Zoning of Annexed Land
Any territory or land annexed to the city after the adoption of this title shall automatically, upon such annexation, be classified
within the R-1 Single-Family Suburban Residential District and be subject to all conditions and regulations applicable to land in

United City of Yorkville Chapter 3. District Standards
Unified Development Ordinance Update Page 3 of 96
Purpose of Residential Districts
A.General Purpose of Residential Districts. Residential zoning districts are established, designed, and intended to provide
a comfortable, healthy, safe, and pleasant environment in which to live and shall:
1.Provide appropriately located areas for residential development that are consistent with the Comprehensive Plan, as
amended; and
2.Ensure adequate light, air, privacy, and open space for residents; and
3.Provide for a variety of neighborhoods with a range of housing types with varying characters and patterns of
development; and
4.Protect neighborhoods from the harmful effects of excessive noise, traffic congestion, and other potential adverse
impacts; and
5.Provide amenities while protecting residents from incompatible uses and activities.
B.R-1 Single-Family Suburban Residence District. The R-1, single-family suburban residence zoning designation is
intended to create a spacious suburban residential neighborhood. To protect the character of the district, permitted uses are
limited to single-family detached housing yet accommodate other compatible and complementary cultural, religious,
educational, and public uses.
C.R-2 Single-Family Traditional Residence District. The R-2, single-family traditional residence zoning designation is
intended to accommodate smaller, more conventional suburban residential neighborhoods. The primary permitted uses are
single-family detached housing in addition to compatible and complementary cultural, religious, educational, and public
uses.
D.R-2D Duplex, Two-Family Attached Residence District. The R-2D, duplex, two-family attached residence zoning
designation is intended for moderate density duplex dwelling structures. This district is primarily located off of a major
thoroughfare or as a transitional land use adjacent to single-family residences. Therefore, the R-2D, duplex district is
intended to accommodate single-family attached dwelling structures of a size and character that are compatible with the
surrounding single-family detached residential districts and adjacent to commercial, office and retail space.
E.R-3 Multi-Family Attached Residence District. The R-3, multi-family attached residence zoning designation is intended
for moderate density residential developments near commercial areas and transportation corridors, and to promote
economically mixed housing developments and the provision of a range housing types including multi-family buildings such
as duplexes or townhomes.
F.R-4 General Multi-Family Residence District. The R-4, general multi-family residence zoning designation is intended for
moderate to high density multi-family buildings and complexes. This district may accommodate other compatible and
complementary cultural, religious, educational, and public uses.

A.General Purpose of Business and Manufacturing Districts. Business and Manufacturing Districts are established,
designed, and intended to provide a comfortable, healthy, safe, and pleasant environment in which to work, shop, dine,
recreate, and shall:
1.Accommodate retail, commercial, service, and mixed uses needed by Yorkville residents, businesses, visitors, and
workers; and
2.Maintain and enhance the City’s economic base and provide employment opportunities, shopping, entertainment,
restaurant, service and other nonresidential uses close to where people live and work; and
3.Create suitable environments for various types of business and manufacturing uses and protect them from the adverse
effects of incompatible uses; and
4.Allow flexibility to encourage redevelopment and positive improvements to existing uses; and
5.Help ensure that the appearance and operational impacts of business and manufacturing developments do not
adversely affect the character of the areas in which they are located.
B.B-1 Local Business District. The B-1, local business district zoning designation is intended for the location of commercial
and professional facilities that are especially useful in proximity to residential areas. The district is designed to provide
convenient shopping and services that meet the needs and enhance the quality of life for surrounding residential
neighborhoods. This district also encourages dwelling units located above the first floor of a permitted use to create mixed
use buildings.
C.B-2 Mixed-Use Business District. The B-2, mixed-use business zoning designation is intended to accommodate
pedestrian oriented mixed-use corridors and districts with a range of business, service, office, and residential uses including
the Downtown.
D.B-3 General Business District. The B-3, general business district zoning designation is intended for the location of a broad
range of commercial uses, including small-scale and large-scale businesses. These uses are usually oriented toward
automobile access and visibility; therefore, they are typically set along major arterial roads. The businesses in this district
are meant to serve regional as well as local customers. This district also encourages dwelling units located above the first
floor of a permitted use to create mixed use buildings.
E.M-1 Limited Manufacturing District. The M-1 limited manufacturing district zoning designation is intended to provide for
the location of a broad range of warehousing, manufacturing, and industrial uses of minimal environmental impact. The
intensity and impact of uses shall be controlled through the special use permitting process to ensure compatibility with
adjacent land uses through the minimization of off-site impacts. Related uses such as indoor event or recreation
conversions or employee supporting educational, service or limited commercial uses may also be appropriate.
F.M-2 General Manufacturing District. The M-2 general manufacturing district zoning designation is intended to provide for
the location of manufacturing, industrial, and related uses that have greater off-site impacts than those in the M-1 limited
manufacturing district. The district is intended to ensure the compatibility of the manufacturing and industrial uses with
surrounding residential and commercial uses and to minimize off-site impacts such as noise, traffic, and visual qualities.

These regulations are also intended to provide for the protection, conservation and utilization of high quality natural
resources; preservation of wildlife habitats; creation of scenic vistas; provision of public gathering areas or facilities for safe
and accessible outdoor space; connectivity between other green infrastructure via bike and hiking trails and paths; and to
maintain or establish appropriate buffers between differing land use types or intensities.

full force and effect for all properties subject to the provisions of this section.
B.The standards found in this section shall be used by property owners, developers, City staff members, the Planning and
Zoning Commission and the City Council during the design and review of development and redevelopment proposals within
the overlay districts. These standards and criteria complement and add to those contained within the City’s Comprehensive
Plan, as amended, Yorkville Downtown Overlay District Form-Based Code, this title and other land use regulations.
C.D-O Downtown Overlay District. The D-O, Downtown Overlay district designation is intended to guide the development of
a mix of uses and a pedestrian oriented environment, to provide for a mix of housing types for people of all ages and
lifestyles, and to achieve development that is appropriate in scale and intensity for the overlay district and adjacent
neighborhoods.

amended.
2.Intent. It is the intent of this chapter to provide development standards to the United City of Yorkville for downtown and
adjacent redevelopment areas that promote public health, safety, and general welfare of the community, including, but
not limited to the specific purposes set forth below.
a.To guide the development of a mix of uses and a pedestrian-oriented environment as established in the United
City of Yorkville 2016 Comprehensive Plan, adopted September 2016, and the 2019 Yorkville Downtown Overlay
District Streetscape Master Plan.
b.To provide for a mix of housing types within the downtown overlay district and adjacent areas for people of all

Page 46 of 317
United City of Yorkville Chapter 3. District Standards
Unified Development Ordinance Update Page 18 of 96
c.To achieve development that is appropriate in scale and intensity for the downtown overlay district and adjacent
neighborhoods.
3.Overview of The Code.
a.Districts. These regulations are organized within street types for adoption into the City's existing code. These
zoning districts shall be mapped on the City's zoning map; however, the primary streets designation shall be
referenced from Figure 3.19. The following districts are established for mixed use, commercial, and residential
development within downtown and adjacent redevelopment areas. Figure 3.10 illustrates the locations for the
districts.
(1)Bridge Street District
(2)S2: Hydraulic Street District
(3)S3: Van Emmon Street District
(4)S4: "B" Street District
(5)S5: "B" Street-Residential District
b.Building Types. Six (6) building types are defined for use in the street districts. A mix of building types are
typically permitted per district. These building types outline the desired building forms for the new construction and
renovation of structures and contain regulations that determine physical building elements such as build-to-zones,
transparency levels, entrance location, and parking location. Refer to Figure 3.22 for a typical building type page
layout.
c.Site Development Standards. The site development standards provide references to other City ordinances or
parts of the UDO and may include additional information or revision to those ordinances applicable only to the
street districts. These include signage, parking, and landscape.
4.Applicability. These regulations apply to the downtown and adjacent redevelopment areas within the City as mapped
on the City's zoning map. Refer to Figure 3.10 for affected parcels.
5.Conflicting Provisions. In any instance in which the provisions of this section overlap or conflict with other areas of
the UDO, the requirements of this section shall govern.

Figure 3.16 Hierarchy of Street Types
7.Hierarchy of Districts. Development under this code is regulated by street type. The various street types are related
to each other in a hierarchical manner. When these streets intersect, the primary street frontage is determined by its
higher order in the hierarchy. The front of a building and its main entrance must face the primary street. Figure 3.16
illustrates the hierarchy of street types.
8.Primary Streets. The primary streets map designates primary, secondary, and tertiary streets within the downtown
overlay district. These designations prioritize the street frontages for locating the front lot line for required amounts
building frontage and allowable amounts of parking frontage. Refer to 3.16.
a.Vehicular Access. Vehicular access is also managed through this street prioritization within the building type
requirements (refer to Section 10-3-13(D)). See Figure 3.17 and Figure 3.18 for illustration of permitted vehicular
access locations.
Figure 3.17 Secondary Street Frontage: Access Drive Permitted Location
Page 61 of 317
United City of Yorkville Chapter 3. District Standards
Unified Development Ordinance Update Page 33 of 96
(1)The order of access is typically as follows, unless otherwise permitted by building type:
(a)Lane (Tertiary Street) or alley (un-mapped) permits unlimited access.
(b)If no lane or alley exists, one (1) driveway per secondary street frontage is permitted.
(c)If no tertiary or secondary street abuts the parcel, one (1) driveway is permitted off the primary street
and shared access with adjacent properties is encouraged.
(2)Refer to the subdivision control ordinance for additional requirements of vehicular access off adjacent
streets. Interparcel access requirements shall be met.
b.Primary, Secondary, and Tertiary Street Designations.
(1)Primary Streets. Primary streets require the most intact and continuous streetwall with few, if any, driveway
access. The front lot line shall always be located on the primary street. When a parcel is fronted by more
than two (2) primary streets, the Zoning Administrator shall determine which is the appropriate street for the
front lot line. The determination should be based on locations of existing and other proposed development
front lot lines.
(a)Vehicular access should not be located off a primary street, unless no other options exists. Refer to
Section 10-3-13(D) Building type requirements for allowances of vehicular access, if applicable.
(2)Secondary Streets. Secondary streets are intended to have a fairly continuous streetwall,but will likely have
a driveway for each parcel. If no tertiary street exists, access will likely be off the secondary street.
(3)Tertiary Streets. Tertiary streets typically have no streetwall requirements and could be fronted by parking
structures and parking lots with multiple drives and/or vehicular access points.

(2)Street trees shall be located in either a landscape zone (within a planting bed or lawn) or a furnishings zone
(in trees wells with grate as required).
(3)Permeable Surface. For each tree preserved or planted, a minimum amount of permeable surface area is
recommended.
(a)Preserved trees should have a permeable surface area equal to the critical root zone. The critical root
zone is equal to half of the radius of the tree's mature canopy, measured from the trunk out to the
dripline.
(b)Planted trees have a suggested minimum permeable area and soil volume based upon tree size; refer
to Table 10-3-13(E)(4)(b) for details.

Off-Street Parking and Loading
A.Purpose. The purpose of this section is to regulate off-street parking and loading areas on private property outside the
public right-of-way. The regulations are intended to achieve the following:
1.Relieve traffic congestion on streets by providing adequate, but not excessive, off-street parking;
2.Encourage the use of alternate forms of transportation including bicycling, transit, walking, and ride sharing services;
3.Avoid unnecessary conflicts between vehicles, bicycles, and pedestrians; and
4.Minimize negative impacts on adjacent properties and the environment.
B.General Provisions.
1.Application. The off-street parking and loading provisions in this section shall apply to the following:
a.New Development. All new buildings, structures, and land uses established after the adoption of this title must
comply with the parking and loading regulations established in this section.
b.Expansion. When an existing building or structure increases in intensity or is expanded, the number of parking
spaces and/or loading facilities must be modified to meet the parking and loading regulations. The number of
parking spaces and/or loading facilities that must be modified will be determined by the unit of measurement
specified for that land use in Table 10-5-1(H)(5). However, no building or structure lawfully erected or use lawfully
established prior to the effective date shall be required to provide additional parking spaces and/or loading
facilities unless the aggregate increase in units of measurements is greater than fifteen (15) percent.
c.New Use. Whenever the existing use of a building or structure is changed to a new use, parking or loading
facilities shall be provided as required for such new use, unless otherwise approved as a Variation as detailed in
Section 10-8-9. However, if said building or structure was erected prior to the effective date of this title, additional
parking or loading facilities are mandatory only in the amount by which the requirements for the new use would
exceed those for the existing use if the latter were subject to the parking and loading provisions of this title.
2.Existing Parking and Loading Facilities. Accessory off-street parking or loading facilities which are located on the
same lot as the building or use served and were in existence on the effective date of this title shall not be required to
Page 173 of 317
United City of Yorkville Chapter 5. Development Standards
Unified Development Ordinance Update Page 2 of 46
reduce the amount of parking and loading facilities regulated in this title. A change of occupancy is not a change of use
unless the new occupant is considered in a different use classification.
3.Control of Off-Site Parking Facilities. Where required parking facilities are provided on land other than the zoning lot
on which the building or use served by such facilities is located, they shall be and remain in the same possession or
ownership as the zoning lot occupied by the building or use to which the parking facilities are necessary. No such off-
site parking facilities shall be authorized and no zoning certificate shall be issued where the plans call for parking
facilities other than on the same zoning lot until and unless approved as an Variation as detailed in Section 10-8-9.
Prior to approval as an Administrative Exception, the owners of the multiple properties shall provide an agreement in a
form approved by the City Administrator with consultation from the City Attorney attesting that the off-site parking
facilities will be maintained at all times during the life of the proposed use or building.
C.Use of Parking Areas.
1.All required off-street parking areas shall continually be available for the parking of operable vehicles of intended users
of the site.
2.No off-street parking area shall be used for storage of equipment or materials except where otherwise approved.

F.Access and Cross Access.
1.Access. To ensure safe and efficient means of automobile access for all parking spaces, each required off-street
parking space shall open directly upon an aisle or driveway unless the facility is serviced by a parking attendant.
2.Cross Access. To facilitate vehicular access between adjoining developments, encourage shared vehicle parking, and
minimize access points along streets, new multi-family, nonresidential, and mixed-use development or redevelopment
shall comply with the following standards:
a.Internal vehicular circulation systems shall be designed to allow for vehicular cross-access between the

mixed-use development.
b.Required vehicular cross access between the adjoining lots shall be provided through the use of a frontage or
service street (if the lots front on a major thoroughfare right-of-way), a single two-way maneuvering lane, or two
one-way maneuvering lanes that are sufficiently wide to accommodate traffic by automobiles, service vehicles,
loading vehicles, and emergency vehicles.
c.The Zoning Administrator may waive or modify the requirement for vehicular cross access on determining that
such cross access is impractical or undesirable because it would require crossing a significant physical barrier or
environmentally sensitive area, would create unsafe conditions, or there exists an inability to connect to adjacent
property. City Council shall have the authority to waive or modify vehicular cross access requirements for all
public review processes involving review by City Council.
d.Easements allowing cross access to and from properties served by a vehicular cross-access, along with
agreements defining maintenance responsibilities of property owners, shall be recorded with the Register of
Deeds for the county in which the properties are located before issuance of a Building Permit for the development.

M.Shared Parking.
1.Purpose. Shared parking is the use of a parking space by vehicles generated by two (2) or more individual land uses
without conflict or encroachment. Shared parking for multiple uses creates better pedestrian connections and reduces
reliance on private vehicles because multiple trips may be taken by walking. Shared parking is encouraged for the
benefits it provides as long as the use follows the conditions and standards listed below.
2.The ability to share spaces is the result of two (2) conditions:
a.Vehicles accumulate at different times; either by hours, days, or seasons.
b.Relationship of the uses allows for multiple visits in one (1) auto trip.
3.Shared Parking Uses. The uses listed subsections (a) and (b) are uses that are generally considered prime
candidates for shared parking. While these are considered the main uses to have shared parking, the Zoning
Administrator has the final authority on what uses may or may not share parking regardless of if the use is listed in the
subsections below or not.
a.For purposes of this Section, the following uses are considered daytime uses:
(1)Office Uses,
(2)Commercial Service Uses,
(3)Commercial Retail Uses,
(4)Industrial Uses, and
(5)Other similar primarily daytime uses, as determined by the City Council.
b.For purposes of this Section, the following uses are considered evening or weekend uses:
(1)Physical Health and Entertainment Uses,
(2) Public/Semi-Public Uses,
(3)Eating and Drinking Uses, and
(4)Other similar primarily nighttime or weekend uses, as determined by the City Council.
Page 185 of 317
United City of Yorkville Chapter 5. Development Standards
Unified Development Ordinance Update Page 14 of 46
4.Standards.
a.The applicant must demonstrate that the shared parking area has a sufficient amount of spaces for the uses they
intend to share the area with. The Zoning Administrator may require the applicant to provide data to support the
sufficient parking claim.
b.The nearest parking space shall be no farther than one thousand (1,000) feet from the principal buildings,
structures, or uses. The path from the parking space to the principal building should consider:
(1)Adequate lighting.
(2)Separation from the right-of-way.
(3)Legal crosswalks for right-of-way crossing.
(4)Asphalt, concrete, or similar surface material.
c.A legal document between the property owners that guarantees access to the shared parking must be submitted
to the Zoning Administrator. The document will be approved by the City before being recorded. The termination of
the agreement must be approved by the City and the owners must provide proof that each establishment meets
the criteria within this title.
N.Pedestrian Circulation Standards.
1.Off-street parking areas shall include on-site pedestrian circulation systems to ensure the safety of pedestrians,
bicyclists, and motorists.
2.The on-site pedestrian circulation system shall comply with all ADA standards.
3.The on-site pedestrian circulation system shall be marked and must connect all buildings on the site to one another
and provide connections to the required vehicle and bicycle parking spaces.
4.The on-site pedestrian circulation system must connect building entrances to adjacent public rights-of-way along direct
routes that do not require significant out-of-direction travel.
5.The on-site pedestrian circulation system shall provide at least one (1) connection to adjacent properties along a
shared street frontage. Connections must provide access to existing walkways on adjacent properties, or to the likely
future location of walkways on those properties. The Zoning Administrator may waive this requirement upon
determining that no walkway exists, a future walkway is unlikely to exist, or such connection would create a safety
hazard.
6.Connections to existing and future planned trails shall be provided.

United City of Yorkville Chapter 5. Development Standards
Unified Development Ordinance Update Page 15 of 46
O.Bicycle Parking. The purpose of this section is to provide sufficient, safe, and convenient bicycle parking to encourage
bicycling as a form of transportation, reducing traffic congestion, air pollution, wear and tear on roads, and use of fossil
fuels, while fostering healthy physical activity.
1.Types of Parking. The following types of bicycle parking shall be allowed:
a.Short-Term Parking.
(1)Bicycle Rack. A bicycle rack is a device that is capable of supporting a bicycle in a stable position that
secures the bicycle with at least two (2) points of contact. A single rack provides two (2) parking spots. The
rack shall be no taller than three (3) feet tall and no less than eighteen (18) inches in length.
(2)Bicycle Shelter. A bicycle shelter is a covered parking area and provides all weather protection. The shelter
should be designed to hold many bicycles. It is preferred that the shelter be close to other forms of
transportation to encourage bicycle riding throughout the City.
b.Long-Term Parking.
(1)Bicycle Locker. A bicycle locker provides an all-weather, high security, and long-term parking solution. The
enclosure should be made out of durable material that will keep the bicycle safe from weather or vandalism.
The locker must be able to be locked to prevent theft and it must be able to be unlocked by the user for easy
access. It is preferred that bicycle lockers are placed near other forms of transportation to encourage bicycle
riding throughout the City.
(2)Bicycle Station. A bicycle station provides the highest level of service for long term parking. The station is
intended to be a regional hub for bicycles in the area and it is expected for the station to provide services to
cyclists. These services may include, but are not limited to, repair, lockers, showers, food and beverages,
rental, and other storage facilities.
2.Off-Street Parking Reduction For Bicycle Parking.
a.A reduction in the number of off-street vehicle parking spaces required shall be permitted for the provision of
bicycle parking provided that:
(1)No fee is required for using the bicycle parking made available;
(2)When calculation of the maximum number of reduced parking spaces results in a fraction, the resulting
number shall be rounded to the next highest integer.
b.The reduction in the number of vehicle parking spaces shall be reduced by no more than one (1) space for every
two (2) bicycle parking spaces, but no more than five (5) percent of the total required spaces.
c.This provision is applicable to all land uses except single-family residential and duplex residential.
P.Land Banked Parking Facilities. Land banking allows for the designation of a portion of land on a site that would be
required for parking to be held and preserved as open space, rather than constructed as parking. This reduces the amount
of impervious surface on a site for developments which otherwise would not have enough parked vehicles to fill the
minimum required parking stalls, or "bank" the spaces until such time capacity warrants their construction.
1.Standards. The Planning and Zoning Commission may recommend to the City Council land banking of up to twenty-
five (25) percent of the required parking spaces through the Variation process, as defined in Section 10-8-9 of this
ordinance.
2.Land Bank Plans Required. The owner of the property making a land bank request shall submit a detailed land
banked parking plan for review by the Planning and Zoning Commission with final approval by the City Council. The
Page 187 of 317
United City of Yorkville Chapter 5. Development Standards
Unified Development Ordinance Update Page 16 of 46
land banked parking plan shall show both full compliance with the parking regulations of this chapter and the land bank
area showing the reduced number of parking spaces.
3.Termination of Land Bank.
a.The City Council shall have the right in its discretion to require the property owner or successor, to construct all or
a portion of the land banked parking facilities. Instances for termination, shall include, but not be limited to:
(1)The intensity of the use is increased,
(2)The type of use changes,
(3)There is an addition to the property or building.
b. The Zoning Administrator will provide notice to the owner that the land banked parking facilities must be
constructed and completed within one (1) year from the date of the notice.
Q.Off-Street Loading Regulations and Requirements.
1.Location. All loading berths shall be located on the same zoning lot as the use served. No loading berth for vehicles
over two (2) tons of capacity shall be closer than fifty (50) feet to any property zoned or used for residential purposes
unless all loading and unloading activities are located completely within the building, screened by the requirements for
Transition Area D as detailed in Section 10-5-3(F)(3). No permitted or required loading berth that is open to the sky
shall be located within any front or corner side yard and shall not be located within fifty (50) feet of the nearest point of
intersection of any two (2) streets.
2.Size. Required size shall be determine on a case-by-case basis depending on the narrative provided by the petitioner

berth.
4.Repair and Service. No motor vehicle repair work or service of any kind shall be permitted in conjunction with loading
facilities provided in any district.
5.Loading Spaces Not to be Used for Parking Requirements. Space allocated to any off-street loading berth shall
not, while so allocated, be used to satisfy the space requirements for any off-street parking facilities or portions thereof.
6.Special Uses. For special uses other than prescribed hereinafter, loading berths adequate in number and size to serve
such use, as determined by the Zoning Administrator, shall be provided.
7.Required Off-Street Loading Spaces. The number of loading spaces provided shall be determined on a case-by-
case basis as approved by the Zoning Administrator and based on a narrative provided by the petitioner or traffic
study. These spaces shall be provided in a manner that does not interfere with internal site circulation, ingress or
egress to the site, access to or use of required off-street parking areas and pedestrian circulation areas, and with the
public use of streets or alleys.

Appearance Standards
A.Applicability. The provisions of this Code shall apply to:
1.Building permits for new construction applied for after the execution hereof; and/or
2.Building permits for additions to existing commercial or industrial buildings where the permit is applied for after the
execution hereof and where the cumulative addition(s) is equal to ten (10) percent of the floor area or two hundred
(200)square feet, whichever is more; and/or
3.The standards in this Code shall be prorated when being applied to additions to all principal buildings or major
reconstruction (i.e., twenty-five [25] percent of the facade is removed and/or different type of facade material is used
and/or if the size of windows/doors are being modified by more than twenty-five [25] percent) done to nonresidential or
attached single-family or multi-family buildings.
4.Additions and/or major facade work shall be assessed on a cumulative basis (i.e., if a ten [10] percent modification is
conducted at one [1] time and later another ten [10] percent modification is made, the cumulative impact is twenty [20]
percent and therefore, a twenty [20] percent compliance ratio is expected).
B.Exceptions. The provisions of this Code shall not apply to:

Unified Development Ordinance Update Page 44 of 46
(1)The building footprint of single-family attached and multi-family buildings can be the same. However, the
facade treatments must vary between buildings that are adjacent to one another. Facade variations may
include building materials or colors in any one (1) or more of the following:
(a) Siding;
(b) Masonry;
(c)Roof;
(d) Paint/stain;
(e) Doors.
(2)Sites where requested setbacks and yards are less than the minimum zoning district requirements must
provide an interesting relationship between buildings.
(3)Parking areas shall be treated with decorative elements, building wall extensions, plantings, berms and other
innovative means so as to largely screen parking areas from view from public ways.
(4)The height and scale of each building shall be compatible with its site and adjoining buildings.

underground.
(6)The architectural character of the building shall be in keeping with the topographical dictates of the site.
(7)Masonry products shall be incorporated on the front facade of at least seventy-five (75) percent of the total
buildings in the approved community, and shall incorporate a minimum of fifty (50) percent premium siding
material on the front facade. No less than half (twenty-five (25) percent of the total) of the minimum "premium
siding" requirements must incorporate masonry products. Credit toward the remaining "premium siding"
requirement can be earned via the use of major architectural features. Each major architectural feature used
will earn a credit of ten (10) percent towards the calculation of the minimum premium siding requirement.
(a)Example: A building with thirty (30) percent masonry on the front elevation will require the use of two (2)
"major architectural features" (ten [10] percent + ten [10] percent = twenty [20] percent) to comply with
the total "fifty (50) percent premium siding material on the front facade".
(8)Pedestrian features/amenities, such as covered walkways, street furniture, and bicycle rack facilities are
encouraged.
(9)Common open space and outdoor features are encouraged.
3.Nonresidential.

Safety, Maintenance, and Abandonment ......................................................................................................................... 23
Purpose and Scope
A.Purpose. The purpose of this Chapter is to set out regulations for the erection and maintenance to ensure the appropriate
appearance of signs while preserving the right of free speech and expression in keeping with the following principles.
1.The ability to display signs of reasonable size and dimensions is vital to the health and sustainability of many businesses,
and the display of signs with noncommercial messages is a traditional component of the freedom of speech, but the
constitutional guarantee of free speech may be limited by appropriate and constrained regulation that is unrelated to the
expression itself,
2.The City has an important and substantial interest in preventing sign clutter, which is the proliferation of signs of
increasing size and dimensions as a result of competition among property owners for the attention of passing motorists,
because sign clutter degrades the character of the community, makes the community a less attractive place for
commerce and private investment, and dilutes or obscures messages displayed along the City’s streets by creating visual
confusion and aesthetic blight,
3.Sign clutter can be prevented by regulations that balance the legitimate needs of individual property owners to convey
messages against the comparable needs of adjacent and nearby property owners and the interest of the community as
a whole in providing for a high-quality community character,
4.Temporary signs that are not constructed of weather-resistant materials are often damaged or destroyed by wind, rain,
and sun, and after such damage or destruction, degrade the aesthetics of the City’s streets if they are not removed,
5.The City has an important and substantial interest in keeping its rights-of-way clear of obstructions and litter,
6.The City has an important and substantial interest in protecting the health of its tree canopy, which contributes to the
character and value of the community, and
7.The uncontrolled use of off-premises advertising signs can be injurious to the public, and destructive to community
character and property values, and that, as such, restrictions on the display of off-premises commercial signage are
necessary and desirable.
Page 219 of 317
United City of Yorkville Chapter 6. Sign Standards
Unified Development Ordinance Update Page 2 of 24
B.Scope. The regulations of this Chapter shall provide a balanced and fair legal framework for design, construction, and
placement of signs that:
1.Promotes the safety of persons and property by ensuring that signs do not create a hazard by:
a.Collapsing, catching fire, or otherwise decaying,
b.Confusing or distracting motorists, or
c.Impairing drivers' ability to see pedestrians, obstacles, or other vehicles, or to read traffic signs.
2.Promotes the efficient communication of messages, and ensures that persons exposed to signs:
a.Are not overwhelmed by the number of messages presented, and
b.Are able to exercise freedom of choice to observe or ignore said messages according to the observer’s purpose,
and
3.Protects the public welfare and enhances the appearance and economic value of the community by protecting scenic
views and avoiding sign clutter that can compromise the character, quality, and viability of commercial corridors,
4.Ensures that signs are compatible with their surroundings, and prevents the construction of signs that are a nuisance to
occupants of adjacent and contiguous property due to brightness, reflectivity, bulk, or height,
5.Promotes the use of signs that are aesthetically pleasing, of appropriate scale, and integrated with the built environment,
to meet the objectives related to the quality and character of development set forth in the Comprehensive Plan of the
City of Yorkville,
6.Enhances property values and business opportunities,
7.Assists in wayfinding, and
8.Provides fair and consistent permitting and enforcement.

Comprehensive Sign Plan
A.Intent. The intent of the comprehensive sign program is to provide an alternative procedure under which signs can be
designed, constructed, and erected with innovation, imagination, and creative architecture. The objective of the
comprehensive sign plan is to encourage a higher level of design and amenity than is possible to achieve under otherwise
applicable sign regulations.
B.Applicability. Any building or development may elect to submit a comprehensive sign plan. After the approval of a
comprehensive sign plan, no permanent sign shall be erected, placed, or maintained except in conformance with the
Comprehensive Sign Plan.
C.Conditions. The Zoning Administrator may attach conditions, requirements, or standards necessary to assure that the
signs covered by the Comprehensive Sign Plan will not be materially detrimental to persons or property in the vicinity. In
making its determination, the Zoning Administrator shall not base any condition on the content of a sign.
D.Evaluation Criteria.
1.Placement. All signs shall be placed where they are visible and legible. Factors to be considered include the location
of a sign relative to traffic movement and access points, site features, other structures, and orientation relative to
viewing distances and viewing angles. Wall Signs may be approved on building walls other than the wall of a unit of a
multi-tenant building in which some units have little or no visibility from the street.
2.Quantity. The number of signs that may be approved within any development shall be sufficient to provide necessary
facilitation of internal circulation of vehicular and pedestrian traffic and wayfinding for safety of the occupants of
vehicles and pedestrians. Factors to be considered shall be those that impact safety considerations such as the size of
the development and the number of development sub-areas.
3.Size. All signs shall be no larger than necessary for visibility and legibility but in no instance shall the sign area or sign
height exceed the maximum established per sign type per district. Factors to be considered in determining appropriate
size include topography, volume, and speed of traffic, viewing distances and angles, proximity to adjacent uses, and
placement of display.
E.Application. A comprehensive sign plan shall be submitted on a form established by the Zoning Administrator. The
application shall contain the following information as well as all other information required by the Zoning Administrator to
ensure compliance with the comprehensive sign plan evaluation criteria.
1.Name, address, and telephone number of the applicant.
2.Location of building, structure, or lot to which or upon which the comprehensive sign plan shall apply.
3.Name of person, firm, corporation, or association developing the comprehensive sign plan.
4.Written consent of the owner or lessee of the building, structure, or land to which the proposed comprehensive sign
plan is applicable.
5.Scale drawing of all signs included in the comprehensive sign plan indicating the dimensions, the materials to be used,
the type of illumination, if any, and the method of construction and attachment. Said drawings shall be drawn at a scale
no smaller than one-eight (1/8) inch equals one (1) foot and shall be prepared, signed, and sealed by a registered
professional engineer when required by the Zoning Administrator.
6.A scale drawing indicating the location and position of all signs included in the comprehensive sign plan in relation to
nearby buildings or structures. Said drawing shall be at a scale no smaller than one (1) inch equals fifty (50) feet.
F.Review and Action. The Zoning Administrator shall review the comprehensive sign plan application and approve, approve
with conditions, or deny the application based on the evaluation criteria. A written decision including the findings on the
evaluation criteria shall be rendered to the applicant.
Page 240 of 317
United City of Yorkville Chapter 6. Sign Standards
Unified Development Ordinance Update Page 23 of 24
G.Appeals. Any applicant who receives a notice of denial from the Zoning Administrator may, within thirty (30) days after
receipt of such decision, appeal such decision to the Board of Adjustment by filing a written notice of appeal with the Zoning
Administrator with an explanation as to why said decision was not warranted according to the applicant.
Prohibited Signs and Content
A.Prohibited Signs. The following sign types shall be prohibited in all districts:
1.Pole/Pylon Signs
2. Billboards
3.Roof Signs
4.Outline Lighting
5.Signs located on City property without the City’s permission
6.Signs which encroach on the public right-of-way
B.Prohibited Content.
1.The following content is prohibited without reference to the viewpoint of the individual speaker:
a.Content that is prohibited or restricted per state or federal statute.
b.Text or graphics that advertise unlawful activity,
c.Text or graphics that are obscene, fighting words, defamation, incitement to imminent lawless action, or true
threats, or
d.Text or graphics that present a clear and present danger due to their potential confusion with traffic control signs
or signs that provide public safety information (for example, signs that use the words "Stop," "Yield," "Caution," or
"Danger," or comparable words, phrases, symbols, or characters in such a manner as to imply a safety hazard
that does not exist).
2.The narrow classifications of content that are prohibited by this subsection are either not protected by the United States
or Illinois Constitutions or are offered limited protection that is outweighed by the substantial governmental interests in
protecting the public safety and welfare. It is the intent of the City Council that each paragraph of this Subsection be
individually severable in the event that a court of competent jurisdiction were to hold one or more of them to be
inconsistent with the United States or Illinois Constitutions.
Safety, Maintenance, and Abandonment
A.Every sign and all parts thereof, including framework, supports, background, anchors and wiring systems shall be
constructed and maintained in compliance with applicable building and other codes adopted by the City.
B.All signs, together with all supports, braces, guys, and anchors shall be kept in proper repair in accordance with the
provisions of this Title. When not galvanized or constructed of approved corrosion resistive, noncombustible materials, signs
shall be painted when necessary to prevent corrosion, rust, peeling paint, and excessive fading. Failure of owners to keep
signs maintained in good mechanical and visual repair shall be deemed a violation of this Title.
C.It shall be the duty and responsibility of the owner or lessee of every sign to maintain the immediate premises occupied by
the sign in a clean condition, free of rubbish.
Page 241 of 317
United City of Yorkville Chapter 6. Sign Standards
Unified Development Ordinance Update Page 24 of 24
D.If the Zoning Administrator shall find that any sign is unsafe or unsecure, or is a threat to the public safety, or was, after the
adoption of this Title constructed, erected, or maintained in violation of the provisions of this title, he or she shall give written
notice per the provisions of this Title. Such notice shall specify the manner in which the sign is unsafe or in violation of this
Title.
E.Sign copy shall be removed and in the case of a wall sign, the building façade shall be repaired, by the owner or lessee of
the premises upon which the sign is located when the use which the sign is associated is no longer conducted on the
premises. The sign copy shall be removed within thirty (30) days of when the use ceases to operate. If the owner or lessee
fails to remove the sign copy, the Zoning Administrator shall give the owner thirty (30) days written notice to remove it.
Failure to comply with the notice shall be deemed a violation of this Title.

Park and Recreation Land and School Site Dedication
As a condition of approval of a final plat of a subdivision, the developer shall dedicate land for park and recreational purposes
and for school sites to serve the needs of residents of the development, or a cash contribution in lieu of the land dedication, or a
combination of both, at the discretion of the City, in accordance with the criteria and formula below.

A.Purpose and Intent. The purpose of the regulations, standards, and criteria contained in this Section is to provide an
alternate procedure under which land can be developed or redeveloped with innovation, imagination, and creative
architectural design when sufficiently justified under the provisions of this Section. The objective of the Planned Unit
Development process is to accommodate a higher level of design and amenity than is possible to achieve under otherwise
applicable UDO regulations. The end result can be a product which fulfills the objectives of City plans and policies, including

2.A Planned Unit Development, if approved, may allow for modifications to the standards of the base district. All such
modifications shall be referred to as site development allowances.
3.Notwithstanding any limitations on Variations which can be approved as contained elsewhere in this UDO, site
development allowances may be approved provided the applicant specifically identifies each site development
allowance in the Planned Unit Development application and demonstrates how each site development allowance
would be compatible with surrounding development; is necessary for proper development of the site; and is aligned
with a minimum of one (1) of the modification standards detailed in Section 10-8-8(D).
4.All approved site development allowances shall be delineated in the ordinance approving the Planned Unit
Development as a Special Use as it applies to the subject property.

s Landscape Ordinance and the Park Development Standards, as amended from time to time.
B.Any existing trees within a development deemed by the Parks Department and Public Works Department to be dead, dying,
or of an undesirable species shall be removed by the developer. The developer shall not remove or cut down any trees
without the prior consent of the Parks Department and Public Works Department, or as indicated in the approved landscape
plan.
Street Lighting
A.All streets shall have a complete street lighting system designed by a professional engineer. A street light will be required at
all intersections, all curves, at all ends of cul-de-sacs, and at a maximum spacing of 300 feet. In Estate-residential
subdivisions, street lights shall be required at intersections, and at a maximum spacing of 500 feet, with lights also placed at
curves and a he end of dead-end streets. The poles shall be concrete with butt-type foundations. The City Engineer may
require a streetlight to be placed at other points, as may be necessary in the public interest in unusual or special conditions.
They shall be located at side lot lines, and on the opposite side of the street from the' water main, wherever possible, and
shall be set two feet from back of curb to face of pole. Occupancy permits cannot be issued until all streetlights in that phase
of the development are installed, complete, and operational.
B.AU exterior lighting of private property in new developments shall be designed, located, and mounted at heights no greater
than twenty (20') feet above grade for non-cutoff lights, and forty- (40') feet above grade for cutoff lights. The lighting plan,
photometrics, and shop drawings for lighting equipment shall be submitted prior to issuance of a building permit. Glare shall
be minimized to the extent practical by orienting lights away from the public right-of-way and abutting properties, or by
planting vegetation to provide screening. Exterior lighting shall be designed, located, and mounted so that the maximum
illumination measured horizontally at the lot line does not exceed one (l ') foot-candle.
C.Light Distribution. Luminaries of the Type II distribution as approved by the Illuminating Engineering Society (herein
termed IES) shall be used, except at intersections where Type II or Type IV IES distribution shall be used. The City
Engineer may designate the IES Type V distribution luminaries be used in the public interest under unusual or special
conditions.

H.Underground Cable. All underground cable shall be direct-buried cable, placed at a depth at least thirty-(30") inches below
the normal finished grade. Three cables (Black, White, Green) shall be run from the pole to the power supply. Any
underground cable broken more than once prior to Final Acceptance shall be replaced from the power source to the pole or
from pole to pole.
I.Splices. All cable on the underground cable section shall be continuous, and no splicing shall be made underground. All
necessary splices shall be made above ground level.
J.Underground Cable Location. Underground cable shall be installed in a trench not less than two feet from the back of the
curb, except that in no case shall the underground cable be installed under the sidewalk.
K.Grounding. A copper-clad ground rod shall be placed at each pole. The rod shall be minimum 5/8-inch diameter, and ten
(10') feet long.
L.Fusing. All underground feeders shall be fused at or below their rated capacity. Each standard shall contain in-line fuse
holders, with proper fusing in series with each underground conductor to protect the luminaire located on that pole.
M.Maintenance Prior to Acceptance. Once streetlights are operational, the Yorkville Public Works Department shall perform
normal maintenance, even though the Yorkville City Council has not accepted the streetlight system. Normal maintenance
consists of investigating the cause of an outage, and repairing it if the cause is a burned out lamp, fuse, or photocell. All
other repairs shall be referred to the developer. The cost of performing normal maintenance prior to acceptance by the
Yorkville City Council shall be paid from a "Streetlight Normal Maintenance" deposit established by the developer prior to
recording the Final Plat. The deposit shall be $300.00 per pole, or other such amount, as may be determined by the
Yorkville City Council, from time to time. If the deposit proves insufficient, the developer shall replenish the deposit within
thirty- (30) days of written request by the City Engineer. The Yorkville City Council shall return any unused funds to the
developer upon acceptance of the streetlight system.
N.Streetlight Standard and Bracket. Local streets shall use 906 B 19-AD4, American Concrete Company pole and bracket,
or approved equal. Luminare shall be mounted 19'9" above the street, shall have a four-(4') foot arm. The pole s.hall be
buried a minimum of five (5') feet below grade and backfilled with crushed CA6 limestone, watered, and compacted around
the butt of the pole. The bracket is to be furnished with the pole.
1.The luminare shall be a General Electric Company No. M2RR1551N2AMS3F, or approved equal with the 1-1/4" side
mount built-in ballast. The luminaries shall be fitted with General Electric Company "Lucalox" high-pressure sodium
lamps LU 150/55/D, or approved equal, with GE Company ANSI specification "S55" high-pressure sodium ballasts (or
approved equal) or American Electric 115 15-S-RN-120-R2-DA- 4B.
O.Major Collector Street. The lighting pole shall be Stress Crete E340-BPO-G, with Style 210 low rise tapered aluminum
davit, or approved equals. The davit outreach length shall be eight (8') feet. The luminaire shall be mounted thirty (30') feet
above the street. The pole shall have an embedment depth of five (5') feet and be backfilled with CA 6 limestone.
1.The streetlight system shall be operated through controller(s) in ground-mounted cabinets. The controller and luminaire
shall operate at 240 volts. The controller shall be housed in a pad-mounted Type NEMA 3R enclosure. The exterior of
the cabinet shall have a bronze tone powder-coat finish. The approximate dimensions of the cabinet shall be 42"H x
36"W x 12"D. A Com Ed meter socket shall be provided on the exterior of the cabinet.
2.The manufacturer or distributor shall guarantee streetlight standards, luminaries, ballast, lamps, and cables for their
proper use, for one year, from the date of acceptance.
P.Testing. The subdivider shall manually trigger the photocell in order to have each street light bum continuously for at least
48 hours. During this bum test, amperage readings shall be taken, and must be within ten (10%) percent of the connected
load, based on equipment ratings.

necessary to achieve a minimum average of 2.0 foot-candies, as measured across the entire parking lot, and a maximum of
Page 306 of 317
United City of Yorkville Appendix A. Standard Specifications For Improvements
Unified Development Ordinance Update Page 8 of 18
1.0 foot-candles, as measured at the adjoining property lines. Parking lots in areas zoned Manufacturing shall have a
minimum average lighting intensity of one foot-candles, per square foot. Lighting shall be designed to avoid casting direct
light or glare onto adjacent residential property.
Storm Sewer System
A.A complete storm sewer system shall be required; consisting of closed conduits to an approved storm water storage
system. All storm sewers within the public right-of-way and easements parallel to and adjacent to public right-of-way shall
be reinforced concrete pipe (RCP), with a twelve (12") inch minimum diameter. Storm sewers in rear yards and side yards
may be high-density polyethylene (H.D.P.E.) of a manufacturer and design, to be approved by the City of Yorkville. All
roadways will have a system of inlets/catch basins, tied directly to the storm sewer. These storm water collection locations
will be on both sides of the street, with a maximum longitudinal flow interval of 300 feet. All such collection points will be an
inlet except the last structure before entering a storm sewer main shall be a catch basin with a two-foot sump. Catch basins
or open-lid structures shall not be located over the sewer main. All backfill is to be a CA 7 aggregate. All storm sewer
roadway crossings from structure to structure must be backfilled with CA7 aggregate and completely encapsulated in an
approved drainage fabric. In this manner, the curb subgrade, the storm crossings, and the inlets and catch basins create a
roadway underdrain system for longer roadway life.
B.The City may require that storm sewers be constructed along the centerline of individual roadways at certain locations.
Those locations shall normally be limited to within 100 feet of the lowest sag vertical curve of a roadway. Where these
locations occur within a horizontal curve of the roadway, storm manholes shall be pf aced at the centerline of individual
roadways.
C.If subgrade conditions are excessively sensitive to moisture or other special conditions, a capped, perforated, plastic
underdrain may be required under the curb and gutter. All storm water conduits 12" diameter and larger shall be 'internally
televised in color just prior to City acceptance, and shall be free of defects, sags, dirt, and debris. All non-RCP storm sewers
shall also be mandrel tested (similar to sanitary sewer testing) just prior to City acceptance. All parking lots shall be drained
internally, and directed by pipe to the storm sewer. Storm sewers shall extend to the limits of the development with proper
sizing, as approved by the City Engineer, based upon current and future runoff conditions, to pick up and safely carry
through the development any and all upstream bypass flows.
D.All new homes with basements or crawl spaces shall have a direct, underground conduit to the storm sewer system. Fill-in
lots in areas with no storm sewer within 500 feet shall not be required to have this direct connection. Minimum depth of
cover for these lines shall be 30 inches. All discharges shall have an approved automatic diverter calve immediately outside
the house and a check valve inside the house. 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.
E.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.

United City of Yorkville Appendix A. Standard Specifications For Improvements
Unified Development Ordinance Update Page 9 of 18
F.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 be 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 be placed at a maximum spacing of 500 feet. Storm sewer manholes may be
four ( 4 ') feet internal diameter when the largest sewer entering/leaving the manhole is 18" diameter, and the orientation of
sewers connecting to the manhole is such that there is at least 12" of precast wall between the openings provided for
sewers. The use of adjusting rings is limited in height to eight (8") inches. Inlet and/or catch basin frames and grates shall
be Neenah No. 3015, East Jordan No. 7010, or approved equal. Whenever possible, castings for curb drains shall have a
fish logo to discourage dumping of oils, pesticides, 'and other inappropriate items into the storm sewer system.
G.Where a continuous grade is carried across an inlet or catch basin casting, the open-vaned cover shall be used, Neenah
No. R-32868V, East Jordan No. EV-7520, or approved equal. All manhole castings shall be Neenah No. R-1030, East
Jordan No. 105123, and Type B cover, or approved equal. All type B covers shall have "City of Yorkville" and "Storm" cast
into the top, and shall be concealed pickhole type. All sections of the manholes shall be completely sealed and butyl rope,
including the casting. Manholes shall no be allowed in the pavement, curb, gutter, or sidewalk. All flared end sections 15" or
larger shall have grates.
H.In Estate residential developments, a ditch shall be required on both sides of the street, and shall have a minimum profile
slope of one (1 %) percent (side slope 4: 1 on the street side, and 3: 1 on the lot side).
I.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.
J.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 based upon actual proposed surface coverage.
Cm then equals 1.25 times Ca.
2.The following run-off co-efficient shall be utilized as minimums:
Surface C
Grass
Asphalt/Concrete
Roof
Detention
.50
.98
1.00
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.
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
Page 308 of 317
United City of Yorkville Appendix A. Standard Specifications For Improvements
Unified Development Ordinance Update Page 10 of 18
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 minimum 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 City 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 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.
a.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.
b.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
Page 309 of 317
United City of Yorkville Appendix A. Standard Specifications For Improvements
Unified Development Ordinance Update Page 11 of 18
the City Engineer directs otherwise, based on site-specific conditions. Drives must be at a minimum 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.
a.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.
b.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.
c.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 m gross area.

depth with aggregate. Except as permitted below, the underground water service pipe and the building drain, or building
sewer, shall be not less than ten feet apart horizontally, and shall be separated by undisturbed or compacted earth. The
water service pipe may be placed in the same trench with the building drain and building sewer if the conditions listed below
are met:
1.Local conditions prevent a lateral separation of ten feet;
2.The bottom of the water service pipe at all points shall be at least 18 inches . above the top of the sewer line at its
highest point. All water and sewer services must be inspected an approved by the building inspector prior to backfilling.
3.The water service pipe shall be placed on a solid shelf, excavated at one side of the common trench, and shall have no
joints from the buffalo box to the water meter inside the house; and
4.The material and joints of sewer and water service pipe shall be installed in such a manner, and shall posses the
necessary strength and durability to prevent the escape of solids, liquids, and gasses there from under all known
adverse conditions, such as corrosion, strains due to temperature changes, settlement, vibrations, and superimposed
loads.
J.Depth of bury shall be 5'6" below finish grade. No joints will be allowed between the corporation stop and the curb stop.
K.All watermain shall be looped and double fed, and shall be extended to the far limits of the development, and in size
appropriate for future development, as directed by the City Engineer. Recapture and over-sizing may be applicable.
L.The developer shall reimburse the City of Yorkville for the cost of water to fill and test new watermains, and also for the cost
of laboratory tests after chlorination. The water cost shall be at the bulk rate charged by the City of Yorkville at that �e. The
volume of water shall be calculated as the volume of two and one-half times the lengths and diameters of new watermains.
M.Watermain proposed to cross existing city streets shall be constructed by directional boring. Open-cut construction shall not
be allowed without consent from the Public Works Director.
N.Connections to existing watermains shall employ line stops to minimize the disruption of service to existing residents.
Sanitary Sewer System
A.A complete sanitary sewer system is required for all new development. The minimum internal size of sanitary sewer main
shall be eight inches in diameter. The top of the sewer main shall be a minimum of three feet lower than the lowest floor
elevation at all service connection locations, but not less than eight feet below finished grade, wherever possible. Should the
sewers serving a particular development not be deep enough to serve the basement, as noted above, then overhead
plumbing will be required. However, all levels of the building must be served by gravity, with only the below-grade levels
being served by a pump unit. The City Engineer may require that certain buildings not have subgrade levels due to special
situations.
B.The sanitary sewer shall be extended to the development's far extremes, as directed by the City Engineer, for proper and
orderly growth. The city Engineer will also direct the sizing and grades for the sewer, so as to fit the overall plan for the City.

R.All public sanitary sewers shall be internally televised in color and recorded on videotape and written log by the developer,
at his expense; under the supervision of the City Engineer, to ensure that the sewers are straight, unbroken, tight, and
flawless. There must be good-quality lighting for a sharp and clear image of all sewer segments. Poor quality images will
result in re-televising the system, at the developer's expense. The videotape must clearly mark the segment being televised
through manhole numbering, and the image must clearly identify the footage as it progresses through the pipe. One copy of
the complete videotapes and written log shall be forwarded to the Yorkville-Bristol Sanitary District, and one complete set
shall be forwarded to the City Engineer.
S.All manholes will be required to be internally vacuum tested by the developer, at his expense, under the supervision of the
Engineer. This test will check the integrity of the complete structure, from the invert to the casting, including all adjusting
rings. One copy of the test results shall be forwarded to the Yorkville-Bristol Sanitary District, and one copy shall be
forwarded to the City Engineer. Vacuum testing of each manhole shall be carried out immediately after assembly backfilling,
and rough grading, and shall be witnessed and approved by the City Engineer. All lift holes shall be plugged with an
approved non-shrinking grout. No grout will be placed in the horizontal joints before testing. All pipes entering the manhole
shall be plugged, taking care to securely brace the plugs from being drawn into the manhole. The test head shall be placed
at the inside of the top of the casting and the seal inflated in accordance with the manufacturer's recommendations. A
vacuum of ten inches of mercury shall be drawn and the vacuum pump shut off. With the valve closed, the time shall be
measured for the vacuum to drop to nine inches. The manhole shall pass if the time is greater· than 60 seconds for a 48-
inch diameter manhole, 75 seconds for a 60-inch manhole, and 90 seconds for a 72-inch manhole. All manhole castings
shall be Neenah No. R-1030 frame, East Jordan No. 105123, and Type B cover, or approved equal.
T.If the. manhole fails the initial test, necessary repairs shall be made with a non-shrink grout, while the vacuum is still being
drawn. Retesting shall proceed until a satisfactory test result is obtained. If the rim of a sanitary manhole needs to be reset
or adjusted after successful vacuum testing, but before the expiration oft eh one-year warranty period, it shall be sealed and
adjusted properly in the presence of the City Engineer. Failure to do so will require the manhole to be vacuum tested again.
U.All manhole frames shall be Neenah No. R-1030, East Jordan No., 105123, or approved equal, with Type B covers. All Type
B covers shall have "City of Yorkville" and "Sanitary" cast into the lid and shall have concealed pick holes with a machined
surface and watertight rubber gasket seals. All manhole segments, including the frame and adjusting rings, shall be set with
butyl rope joint sealant. Manholes shall be minimum four-foot diameter, and shall not be located in pavement, curb, gutter,
or sidewalk.
V.All sanitary sewer manholes shall be provided with approved cast in place rubber boots (flexible manhole sleeve), having a
nominal wall thickness of 3/16" with a ribbed concrete configuration and with stainless steel binding straps, properly sized
and installed for all conduits.
W.All manholes shall be reinforced precast concrete, and shall be located at intersections and spaced at a maximum interval
of 300 feet, except that a closer spacing may be required for special conditions. The maximum allowable amount of
adjusting rings shall be eight inches in height using as few rings as possible. All manholes shall be marked at the time of
construction with a four-inch by four-inch hardwood post neatly installed vertically and with a minimum three-feet bury and a
minimum four-foot exposed. The top one-foot of the post shall be neatly painted white.
X.Wells and septic systems are allowed in Estate-residential developments that are not within 250 feet of water and/or sewer
service. When each lot is within 250 feet of water and/or service, that lot may maintain their septic and/or well only until
failure of the septic or well. At that time the lot must, if within 250 feet of the sewer and/or water line hook-up to the sewer
and/or water, as the case may be, connect to the City utilities at the lot owner's sole expense. After connection to the City
Sanitary Sewer System, individual septic fields shall be abandoned by pumping out the tank, knocking in the cover, and
filling with dirt or stone in accordance with Health Department regulations.

A.A traffic study may be required, and shall include:
1.Levels of service for existing conditions;
2.Levels of service for post-construction conditions;
3.All calculations shall be conducted according to the '.'Highway Capacity Manual";
4.Recommendations as to additional/limited access, additional lanes, signalization, etc.
B.If the City of Yorkville requires a traffic study for a development, that study will be contracted for by the City, and paid for by
the developer. The developer shall establish a Traffic Study deposit with the City of Yorkville, in an amount to be determined
by the City Engineer. The City shall return any unused portion of the deposit to the developer upon approval of a Final Plat
or Site Plan.
C.If the land use plan of the development changes during the approval process, the developer may be required to make
additional deposits to fund re-analysis and revisions to the Traffic Study.
D.The need or requirement for a traffic impact study shall be determined during the concept or preliminary planning stage of
the proposed development. The developer/subdivider shall meet with City of Yorkville officials during one of these stages for
the purpose of determining the traffic study requirements. Wlien the City of Yorkville requires that a traffic study be prepared
based upon the above, the study shall include, but not be limited to, addressing the following issues:
1.Introduction. A general description of the proposed development, including it's size, location, the political jurisdiction in
which the site is located, the boundary limits of the study area, and any other information needed to aide in the review
of the development's traffic impacts.
2.Project Description. A description of the existing and proposed land uses of the development. If alternative land uses
are being proposed, the highest trip generation uses shall be assigned for each land use.
3.Site Accessibility. A clear and concise description of the proposed ingress/egress points to the proposed
development, including a sight distance analysis.
4.Existing External Roadway Network. A description of the existing external roadway networking the vicinity of the
proposed development, to include functional classification, primary traffic control devices, signalized intersections,
roadway configurations, geometric features (curves and grades), lane usage, parking regulations, street lighting,
driveways servicing sites across from or adjacent to the site, and right-of-way data. The area of influence shall be
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.
5.Existing AM, PM, and Total Daily Traffic Volumes. 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.

United City of Yorkville Appendix A. Standard Specifications For Improvements
Unified Development Ordinance Update Page 17 of 18
6.Trip Generations 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.
7.Site Generated Trip Distribution and Assignment. The most logically traveled routes in the vicinity of the
development shall be used for trip distribution and assignment 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.
8.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.
9.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.
10.Intersection Capacity Analysis. Proposed access driveways and influenced intersections shall be subject to an
existing, plus projected, capacity analysis. Projected traffic conditions shall include the effects of any committed
developments within the influenced area. The existing and projected levels of service derived from the analysis shall be
used to aid in the 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.
11.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.
12.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 improvements.
