Review of Code Diagnostic Memorandum
Mr. Davis said the committee would be reviewing the diagnostic memo and then engage in questions or
comments. The intent of the memo is to provide an outline on how to move forward and the scope of
the UDO. The first step is to review the Comprehensive Plan, bring the zoning codes up to speed and
determine long range goals, etc. The second step is to review community outreach done to this point
including challenges and feedback received by the consultants. The third step is discussion for the
UDO proposal including reorganization information and recommended revisions.
First Step - Comprehensive Plan:
The first step is to review text and insure graphics represent what should be accomplished, maintain
existing zoning standards and consistency. The Consultants will work with staff to amend zoning maps
as needed. Ms. Noble said the UDO is a 2-year program and the city will be halfway through the
Comprehensive Plan.

The Consultants will evaluate and enhance the downtown overlay district and carry forward the Form
Based Code. They will encourage preservation and re-use of existing buildings, manage downtown
parking and review landscaping standards. In general, they hope to make regulations easier to
understand. Mr. Davis commented that he favors the Form Based Code, but not for the entire
community. One of its challenges is administration of the Code. Promotion of sustainable designs will
be encouraged along with modernized engineering designs and environmental standards, all of which
will be folded into the revised language.
The development process will be streamlined and simplified to be understandable and checks and
balances must be in place. A Conservation District will also be implemented. Public Works will be
consulted regarding cul-de-sac designs, ways to reduce the amount of pavement, sustainable designs
and road connections to future subdivisions.
Second Step - Public Outreach
Ms. Wells opened the discussion for the Public Outreach. Feedback was received from this committee
and also from developers. Some of the topics raised were: 1) Actual parking needed for various
venues—not enough or too much, 2) clarification of landscape regulations, 3) improve and modernize
lighting regulations, 4) rules for multi-tenant building signage, electronic message boards, temporary
signs, LED signs, 5) subdivision standards with more open space, no cul-de-sacs or eyebrow streets,
improved street layouts, conservation areas, 6) administration and enforcement—streamline all
reviews and add administrative relief with level of public review and less need for committee reviews,
7) restart of dormant subdivisions with easier processes for developers, update PUD process to make
less burdensome, use zoning code more instead of adding ordinances.
Ms. Wells asked for other feedback from committee members. Ms. Noble suggested adding the
concept of accessory dwelling units particularly in the older parts of town. This could include living
space converted from garages or attics. Chairman Funkhouser questioned allowing small spaces for
this purpose, though he said garage conversions might be open for discussion.
Committee member Jeff Olson commented on the rationale for pie-shaped lots. Ms. Noble said a
couple developers had extreme angles which created setback issues and the housing for the shape
needing a variance or other relief. She said it would be better to avoid them unless there is adequate
room for setbacks. Other issues raised with these lots is that the streets must be able to accommodate
fire trucks and Public Works maintenance trucks. Chairman Funkhouser asked to have comparisons
done with other communities for cul-de-sacs and eyebrow streets and he said he likes flexibility of lot
sizes. Mr. Olson asked if smaller lots are needed to which Ms. Noble replied they would allow for a
better return of investment for developers and reduce home costs. A deeper lot size would allow for
less infrastructure in the front and the saved money could be put back into the actual home, said Mr.
Funkhouser. He added that Naperville teardowns have zero lot lines. He said narrower lots don't allow
for parking 2 cars, but perhaps parkway space could be used.
Mr. McCue noted there is a need for less expensive homes now and the national builders are building
“boxes”. He suggested smaller lots and requirements for more architectural standards. He said
national builders in Colorado are building beautiful smaller homes based on those standards.
Ms. Noble said sidewalks cost more to build and maintain than asphalt paths and Mr. McCue added
that in one Oswego subdivision, the path is situated in the main section. He said as a builder, he knows
the big equipment goes across the path and they have to do all repairs.

Regarding parking, Mr. Olson said there might not be adequate handicapped parking considering that
baby boomers are reaching retirement age. And he added that parking lots like those in Target, might
have too much parking. Mr. Funkhouser said consultants have studied market standards and have
recommended balanced parking vs. requirements to avoid massive lots. More parking is needed
downtown, he said. In Sugar Grove, parking is severely restricted on the streets at all times, added Mr.
McCue.
Third Step - Discussion for UDO Proposal
Ms. Wells gave a brief overview of the proposed UDO code, saying that many aspects need to be
consolidated and streamlined. She said “General Provisions” is the opening section for all the titles.
This format will allow for easier updates which would go through committee rather than a Public
Hearing. Mr. Olson commented that he is in favor of giving more power to the staff to allow easier
changes. Plain language will be used as well as less legal language, clearer graphics and use of Encode
Plus. Mr. Davis added that simplified graphics, cross references to links and permit fee tables should
also help. Definitions will all be in one section and by hovering over the definition, Encode Plus will
give the ability to pop up other information. Encode will also display standards for types of
developments.
The Use Standards will include tables specifying what type of use is permitted in which zones. Now
the regulations are widely disbursed in the code, but the UDO will bring all of them together into a
single table.
It was stated that signs cannot be regulated by content and this is supported by a court case. Lighting
of the signs was also discussed.
Chairman Funkhouser said that a recent Neighborhood Design Manual should be rolled into the UDO
also. An ordinance was done, however, it is a guide rather than requirement.
Subdivision Standards Comments: Mr. Davis said the recommendations included relocating
administrative requirements for submission, modernizing and introducing new design standards,
conservation design, road connectivity standards, open space requirements including incentivizing
developers, coordinating with Public Works for road engineering design standards, aligning all
application processes, and revising PUD regulations for better outcomes of master plan and
Comprehensive Plan.
Mr. McCue asked if any communities encountered legal challenges when matters were handled by staff
instead of committees and Council. Ms. Wells replied that there are standards for review which are
legally defensible. Ms. Noble also noted there is an appeal process and there was an appeal last year
that was won.
Mr. Davis said the Form Based Code applicability analysis will be incorporated into the UDO and that
the overlay had not been adopted when they drafted this memo.
Appendix Comments: The committee members were all asked to read this.

Project Schedule and Next Steps
Two steps are now completed: Project Initiation and Technical Analysis. The next phase will be the
draft District Standards and Concepts which includes residential/agriculture district standards and
commercial/industrial standards. This will be the next item to consider in February or March. The
committee will also start looking at Special District Standards and a Proposed Zoning District Map.
This will be presented to the public at a later time. It is hoped to send the draft of Chapter 3 to
committee members at least 2 weeks prior to the next meeting after staff has a chance to review first.
Chairman Funkhouser asked the Consultants if there would be any implications for the UDO if the City
became home-rule. The Consultants did not think so.
Adjournment:
There was no further business and the meeting adjourned at 7:12pm.

Minutes respectfully submitted by Marlys Young, Minute Taker
SUMMARY:
This meeting is to review Chapter 5: Development Standards for the Unified Development Ordinance.
This Chapter covers several major topics for development including off-street parking, landscaping,
screening, fencing, and lighting regulations. This Chapter has a great deal of new regulations and
modifications from existing ordinances. Not only has Community Development Staff reviewed this
section but the Building Code Official, Public Works Director, City Engineer, and City Landscaping
Consultant have all provided input to the draft regulations. Staff is seeking feedback from the UDO
Advisory Committee on this Chapter to present to the City’s consultant.
DISCUSSION TOPICS:
While there have been several modifications and additions to the regulations regarding development
standards, staff is seeking specific input on the following topics:
• There has been a slight reduction in parking lot widths for angled parking to reduce overall
potential impervious surfaces. Do you agree with these changes or should they be kept the
same?
• A calculation for a maximum number of required spaces is being introduced to help reduce
potential impervious surface. Do you agree with this idea and is the calculation appropriate?
• Table 10-5-1(H) regulates the required minimum number of spaces. There has been discussion
among staff and the consultant to have different requirements for small and large developments.
Should we have different standards for smaller and larger developments?
• There are also highlighted sections within Table 10-5-1(H) which need better numbers. Many of
these types of uses are unique and may not benefit from a definitive number. Would you
recommend having the Zoning Administrator determine minimum requirements or would
you prefer a definitive number?
• The number of required loading berths has been removed and will be determined as a case by
case basis and mostly dictated by the private developer. Do you agree with the removal of these
regulations to allow more flexibility for developers?
• While not expressly prohibited in the current code, a new section has been added to permit and
regulate ribbon driveways. Should the City regulate and permit these types of driveways?
• Currently, the City does not permit parking in the required side yard. The parking pad regulations
will allow this in the future. Do you agree with this addition?
Memorandum
To: Unified Development Ordinance Advisory Committee
From: Jason Engberg, Senior Planner
CC: Bart Olson, City Administrator
Krysti J. Barksdale-Noble, Community Development Director
Date: December 2, 2021
Subject: Unified Development Ordinance – Chapter 5 Review
• The landscape section has been modified with more robust and up to date standards. There are
several topics which have resulted in much discussion between departments.
o Do you agree with the requirements of foundation landscaping? Is it too much or
not enough?
o Do you believe the parking island and end cap requirements are reasonable?
o The current tree preservation ordinance is extensive. There is a slimmed down version in
the draft ordinance. The consultant has also provided examples of other communities
(attached). What are your thoughts on how the City should handle tree preservation
regulations?
• The condensing of fencing regulations makes a more streamlined ordinance, but it removed
galvanized chain link from the manufacturing district. Should we remove or keep galvanized
chain link from the permitted materials in the manufacturing districts?

Off-Street Parking and Loading
A. Purpose. The purpose of this chapter 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 car- poolingride sharing
services;
3. Avoid unnecessary conflicts between vehicles, bicycles, and pedestrians; and
4. To mMinimize negative impacts on adjacent properties and the environment.
B. General Provisions.
1. Application. The off-street parking and loading provisions in this chapter section shall apply to the following:
a. New Development. All new buildings, structures, and land uses established after the adoption of this chapter title
must comply with the parking and loading regulations hereinin this section. However, if a building permit has been
issued prior to adoption and construction has begun within one (1) year of the effective date, then following the
parking and loading regulations are not required.
a.b. Process Vesting. Once an application for approval of any process specified within this section has been certified
to be complete, it shall be reviewed according to the process, procedures, and standards of this section at the
time of determination, provided that such application has not been abandoned. Any subsequent amendments to
these regulations adopted by the City that become effective after the date of the determination of completeness
shall not apply to the applications pending approval at the time of the adoption of the changes unless the City and
the applicant agree in writing to follow the revised process or application has been abandoned,
b.c. 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 b y the unit of measurement
specified for that land use hereinin section 10-5-1(G). 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 (15%).

d. New Use. Whenever the existing use of a building or structure shall hereafter beis changed to a new use, parking
or loading facilities shall be provided as required for such new use, unless otherwise approved as an
Administrative Exception as detailed in section 10-#-#. However, if the said building or structure was erected prior
to the effective date hereofof 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.
c.
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 hereof of this title shall not be
required to 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. Damage or Destruction. If any building, structure, or use that is in existence on the effective date hereof of this title is
somehow damaged by fire, collapse, explosion or another cause and is reconstructed or repaired, the parking and
loading facilities may be rebuilt to the original form. This shall be allowed only if the original building or use is repaired
to its original form and keeps its original use. In no case shall it be necessary to restore or maintain parking or loading
facilities in excess of those required by this title for equivalent new uses in construction.
4.3. 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 Administrative Exception as detailed in
section 10-#-#. the Zoning Board of Appeals has reviewed the plans and heard the applicant and made findings that
the common ownership or possession of the zoning lot and the site of the parking facilities are reasonably certain to
continue and thatPrior to approval as an Administrative Exception, the owners of the multiple properties shall provide
an agreement in a form approved by 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.
5. Submission of Site Plan. Any application for a building permit, or for a certificate of occupancy where no building
permit is required, shall include therewith a site plan, drawn to scale and fully dimensioned, showing any parking or
loading facilities to be provided in compliance with this title.
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. Required parking shall not be rented, leased, sold, or used for parking that is unrelated to the primary or accessory use
of the site, except if there is a recorded shared parking agreement.
3.2. Also, nNo off-street parking area can shall be used for storage of equipment or materials except where otherwise
approved.
4. All off-street parking facilities for a residential use or within a residential district must be used for passenger
automobiles. These automobiles must be owned by the occupants of the dwelling structure or by the guest of the
occupant.
Commented [JW2]: We would recommend allowing flexibility
from this requirement if site conditions cannot accommodate
additional parking to make it easier for new uses to occupy existing
buildings.

E. The minimum off-street parking space dimensions are shown in Table 10.16.01 of this section. An explanation of how these
dimensions are generally measured is shown in figure 10.16.01 of this section. The parking of mobile food or retail vendor
vehicles shall be an exception to subsection A of this section when in compliance with section 10 -3-14 of this title and title 3,
chapter 5 of this Code.
F. The actual measurements of the stalls and aisles are shown in figure 10.16.02 of this section. The actual stalls and aisle
must be clearly marked as shown in figure 10.16.02 of this section.
G. All measurements start from the edge of the pavement in front of the curb.
H. Drive aisles shall be required in the parking areas that have five (5) or more spaces.
I. All required parking lots, by this Code, shall comply with the accessibility requirements of the State of Illinoi s Accessibility
Code and the ADA.
F. Access and Cross Access.
1. Access. To ensure safe and efficient means of automobile access for all parking spaces, Eeach required off-street
parking space shall open directly upon an aisle or driveway as stated in Table 10.16.01 of this section. This will ensure
safe and efficient means of automobile access for all parking spaces . The only exception is when unless the facility is
serviced by a parking attendant. All off-street parking facilities shall be designed with appropriate means of vehicular
access to a street or alley in a manner which will least interfere with traffic movements.
2. Cross Access. To facilitate vehicular access between adjoining developments, encourage shared vehicle parking, and
minimize access points along streets, new multifamily, 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
development’s vehicle parking facilities and vehicle parking facilities in an adjoining multifamily, nonresidential, or
mixed-use development, or to the boundary of adjoining vacant land zoned to allow multifamily, nonresidential, or
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.
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.

less than 0.5 is rounded down to the next lower whole number, and any fraction of 0.5 or more is rounded up to
the next higher whole number.
b. Area Measurements. Unless otherwise expressly stated, all area-based (square footage) parking standards must
be computed on the basis of gross floor area (GFA).
c. Occupancy or Capacity-Based Standards. For the purpose of computing parking requirements based on
employees, students, residents or occupants, calculations must be based on the largest number of persons
working on any single shift, the maximum enrollment or the maximum fire-rated capacity, whichever is applicable
as determined by the City Planner and the Fire Department.

5. Unlisted Uses. In the case of uses not listed in Table 10-5-1(H)(1) Minimum Parking Requirements, the number of
spaces for a similar use, as determined by the Zoning Administrator, shall apply.
Number of Spaces. The minimum requirements for the number of spaces needed for a certain use is shown in Table 10-5-1(H)
of this section. At the time of permit review, the Zoning Administrator will assign the development a use category. If the category
does not fit one of the descriptions in Table 10.16.03 of this section, then the Zoning Administrator has the right to determine the
amount of off-street parking needed for the building, structure, or use

M.J. 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 above conditions and the 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 in Table 10.16.04 of this section 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
Table 10.16.04 of this section 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
(1) Other similar primarily nighttime or weekend uses, as determined by the City Council.

3.4. 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 feet (1,000') feet from the principal buildings,
structures, or uses. The measurement shall be measured along a path that hasThe measurement shall be
measured along a path that hasThe 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.
K. 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 future planned trails shall be provided,
N.L. 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

DRAFT FOR REVIEW
(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 th at 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 transportatio n 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 p rovide 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 automobile vehicle parking spaces shall be reduced by no more than one (1)
space for every two (2) bicycle parking spaces, but no more than twenty (20) percent (20%) of the total required
spaces.
c. This provision is applicable to all land type uses except to single-unit residential and two-unit residential.
O.M. Land Banked Parking Facilities. Land banking allows for the designationg 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 th e
minimum required parking stalls, or "bank" the spaces until such time capacity warrants their construction.
1. Standards. The Zoning Board of AppealsPlanning and Zoning Commission may permit land banking of up to twenty-
five (25) percent (25%) of the required parking spaces through the variance process, subject to the following:
a. Sufficient evidence is provided by the applicant that supports the reduced parking needs.
b. Approval of a land bank parking plan which illustrates the area proposed for land banking of parking spaces in an
area suitable for parking at a future time.
c. Landscaping of the land banked area must be in full compliance of the zoning regulationswith this title and, at a
minimum, landscaped with turf. As a result of the site plan review process, the Zoning Board of AppealsPlanning
and Zoning Commission may require additional landscaping of the land banked area.
d. The land banked area cannot be used for any other use and must be part of the same zoning lot and all under the
same ownership.
e. As part of the variance process, the applicant must show the area to be banked on the overall site plan and
marked as "Land Banked Future Parking".
Commented [JW10]: We would recommend establishing a
distinct Land Banked Parking Facilities permitting process since the
standards of review for a variance would be impossible for an
applicant for land banking to meet.

3. Preservation of Existing Trees. Preservation of existing high-quality trees within a new development or
redevelopment site is highly encouraged. Preserved trees may fulfill a portion of the landscape requirements
established in this section. Should the applicant propose to maintain existing high-quality trees to count toward
satisfying certain landscape requirements of this title, the Zoning Administrator may, upon receipt of a tree preservation
plan, waive certain landscape requirements if mature, high-quality trees on a lot are proposed to be preserved. If, upon
inspection at the conclusion of the project, trees identified for preservation have been removed, damaged, or are
otherwise in declining condition, all waived required landscape shall be installed.

Re: Tree Preservation Requirements in Jenks and Oak Creek
Unified Development Ordinance Update
The purpose of this memorandum is to portray the tree preservation requirements used in
the updated Unified Development Ordinances in Jenks, Oklahoma, and Oak Creek,
Wisconsin.
Jenks UDO Section 16-6-3 Landscape
Landscape improvements required by this Section shall apply to all non-single-family
development and consist of living plants in a combination of trees, shrubs, native grasses
and/or groundcover. Unless otherwise stated in this Section, all size specifications for
plant materials shall be based upon the time of planting. When caliper is specified for tree
planting, the caliper of the tree trunk shall be measured at six (6) inches above the soil
level. Any plant materials used to meet the requirements of this Section shall not include
any plant material identified as a Regulated Invasive Plant by the Oklahoma Department
of Agriculture, Food, and Forestry.
Oak Creek, Wisconsin - Sec. 17.0505. Landscape
(a) Tree Preservation.
(1) Existing viable trees of twelve (12) inches or greater DBH shall not be removed
from lots within the City without a tree preservation and removal plan prepared by
a certified landscape architect and approved by the Community Development
Director or their designee. DBH is diameter at breast height measured at four
and a half (4.5) feet off the ground or grade level.
(2) The tree preservation and removal plan shall include an inventory of all trees of
twelve (12) inches or greater DBH on a lot.
(3) Every reasonable effort shall be made to incorporate trees identified in the
inventory into the landscape required for the proposed development. The
Community Development Director or their designee must determine that one of
the following criteria apply prior to granting approval to remove a mature, high
quality tree:
a. The tree is dead, dying, diseased, or a threat to public health or safety;
Houseal Lavigne | Yorkville UDO Update Page 2 of 2
b. The tree interferes with the provision of public services or is a hazard to
traffic;
c. The location of the tree prevents development or redevelopment that cannot
be designed to protect the tree.
d. The tree is an identified invasive species.
(4) Viable trees of twelve (12) inches or greater DBH to be removed shall be
replaced in accordance with the following standards.
a. The tree to be removed shall be replaced within one (1) year of the date of
approval and guaranteed as detailed in Section 17.0504(e).
b. Any tree designated for removal on an approved tree preservation and
removal plan shall be replaced at the rate specified in Table 17.0504(d)(4).
Replacement trees shall not be considered as satisfying the landscape
requirements of this Section.
c. In the event that a tree designated for preservation is destroyed, damaged,
or removed during the construction process, such tree shall be replaced at
three (3) times the applicable rate specified in Table 17.0504(d)(4).
d. The value of a tree shall be determined by the Community Development
Director or their designee in accordance with the methods developed by the
Council of Tree and Landscape Appraisers in the most recent Guide for Plant
Appraisal.

Figure Reference Slightly reduced sizes in the
angled parking section to reduce
impervious surface
Perpendicular kept the same as
existing regulations
•Addition of Compact Space Dimensions
•Additional Cross Access Language
•Added Maximum Parking Requirements for Nonresidential Developments
•Required Parking Reduction Table
Pedestrian Circulation Standards
Off-Street Parking and Loading
Big Picture Questions:
1. Table 10-5-1(H) Thoughts on potentially adding different requirements for
smaller/larger developments.
Certain sections need refinement (highlighted). Should discretion be
given to the Zoning Administrator?
2. The required size and number of berths has been removed and will be dictated by private
developments. Do you agree with this removal?
Driveways
•More detailed language on driveways
•Added parking pad regulations
•Multiunit and Nonresidential Driveway Standards
Big Picture Questions:
1. Should we permit Ribbon driveways?
2. Currently, the City does not permit parking in the required side yard. The parking pad
regulations will allow this in the future. Do you agree with this addition?
Landscape
•Complete overhaul and update of existing regulations
•Planting types, landscaping zones, foundation plantings, parking areas, transition zones
•Diversity requirements
•Tree preservation
•Maintenance and Removal
Big Picture Questions:
1. Do you agree with the requirements of foundation landscaping? Is it too much or not enough?
2.Do you believe the parking island and end cap requirements are reasonable?
3.Is the transition zone table clear?
4.The current tree preservation ordinance is extensive. There is a slimmed down version in the draft
ordinance. HL also provided examples of other communities. What are your thoughts on tree
preservation regulations?
Screening and Fences
Screening
•Additional regulations for screening on trash receptacles
•Mechanical unit screening regulations
Fencing
•Condensed fencing regulations for all districts
Big Picture Questions:
1. The condensing of fencing regulations makes a more streamlined ordinance but it removed
galvanized chain link from the manufacturing district. Should we remove or keep galvanized chain
link from the permitted materials in the manufacturing districts?
Outdoor Lighting
•Updated regulations which include LED requirements
•Kept 0 foot-candle regulation at property line
•Still require a photometric plan
Next Steps
Next meeting will cover Chapter 6: Signs
Aiming for a potential January meeting. What days are best?
