Introductions Roll Call The following answered present: Chris Funkhouser, Alderman David Schultz, Engineer-HR Green Jeff Olson, PZC, Construction Billy McCue, Developer Daniel Transier, Alderman Absent: Deborah Horaz, Mike Torrence, Greg Marker, Matt Hively Others Present: Krysti Barksdale-Noble, Community Development Director Jason Engberg, Senior Planner Nick Davis, Hauseal Lavigne Jackie Wells, Hauseal Lavigne 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. Page 2 of 4 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. Page 3 of 4 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. Comments and Questions None Page 4 of 4 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. Transcribed from digital recording, 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? ATTACHMENTS: 1. Chapter 5 – Development Standards (redline) 2.

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%). Commented [JW1]: Existing language from Chapter 16 United City of Yorkville Chapter 5. Development Standards Unified Development Ordinance Update Page 2 of 31 DRAFT FOR REVIEW 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.

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.

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 L.I. Allowed Reductions to Required Parking. Table 10-5-1(I) establishes reductions to required parking that may be approved by the Zoning Administrator. Adjustment Type Criteria Adjustment Amount Pedestrian Access Nonresidential use is located where residents of all residential and mixed-use areas within 1,320 feet of the subject property can walk to and from the nonresidential use on a continuous sidewalk system (ignoring intervening streets). 10% reduction Public Parking Lots Nonresidential use is located within 900 feet of a parking lot that is available for use by the public without charge (either directly or through a validation program in which the subject use participates). 10% reduction Single-family or duplex residential is located along one or more public street frontages where public parking is permitted. One legal on-street parking space (to a maximum of two parking spaces) can be substituted for every required off- street parking space provided the on-street space is located on a public right-of-way immediately abutting the property or tenant space seeking the parking adjustment. Where a partial space straddles an extension of a side property line, the space may be counted by the abutting property owner in front of whose property 50% or more of the space is located. Multifamily residential or nonresidential use located along one or more public street frontages where public parking is permitted. One legal on-street parking space can be substituted for 0.5 of every required off-street parking space provided the on-street space is located on a public right-of-way immediately abutting the property or tenant space seeking the parking adjustment.

Development Standards Unified Development Ordinance Update Page 9 of 31 DRAFT FOR REVIEW 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.

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 secures the bicycle with at least two (2) points of contact. A single rack provides two (2) parking spots.

Development Standards Unified Development Ordinance Update Page 11 of 31 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. United City of Yorkville Chapter 5. Development Standards Unified Development Ordinance Update Page 12 of 31 DRAFT FOR REVIEW 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 and approval by the Zoning Board of AppealsPlanning and Zoning Commission.

Total landscape elements, excluding turf, shall not be comprised of more than twenty (20) percent of any single species or twenty-five (25) percent of any genus. B.H. Tree Preservation and Removal. No live tree(s) with a four (4) inch diameter at breast height may be removed without first applying for tree removal and receiving approval from the City as specified in Section ###. 1. Tree preservation and removal guidelines. Every reasonable effort shall be made to retain existing trees shown in the tree survey through the integration of those trees into the site and landscape plan for a proposed development. a. Critical areas such as floodplains, steep slopes, and wetlands, should be left in their natural condition or only partially cleared. b. Roadways, storage areas, and parking lots should be located away from valuable tree stands. c. Cutting and filling in the vicinity of valuable trees should be minimal. d. If more than one-third of the tree’s root system is to be affected by construction, the tree should be part of the removal plan and replaced with the appropriate number of trees. 2. Tree Replacement Standards. a. Any tree approved for removal shall be replaced with new trees in accordance with the following schedule: b. In the event that a tree identified to be preserved is removed or damaged, such tree shall be replaced as follows: Caliper (Inches) of tree to be removed Number of Replacement Trees 30 or greater 6 13-29 5 8-12 4 4-7 2 Table 10-5-3(H)(2)(a) Tree Replacement Standards Commented [TP17]: Suggest adding a definition of the term ‘native’ as it relates to plants.

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.
