1. 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. 1.
      Relieve traffic congestion on streets by providing adequate, but not excessive, off-street parking;
   2. 2.
      Encourage the use of alternate forms of transportation including bicycling, transit, walking, and ride sharing services;
   3. 3.
      Avoid unnecessary conflicts between vehicles, bicycles, and pedestrians; and
   4. 4.
      Minimize negative impacts on adjacent properties and the environment.
2. B.
   General Provisions.

   1. 1.
      Application. The off-street parking and loading provisions in this section shall apply to the following:

      1. 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.
      2. 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.
      3. 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. 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 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. 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.
3. C.
   Use of Parking Areas.

   1. 1.
      All required off-street parking areas shall continually be available for the parking of operable vehicles of intended users of the site.
   2. 2.

      No off-street parking area shall be used for storage of equipment or materials except where otherwise approved.

4. D.
   Requirements For All Parking.

   1. 1.
      Drive aisles shall be required in the parking areas that have five (5) or more spaces.
   2. 2.
      All required parking lots, by this Code, shall comply with the accessibility requirements of the State of Illinois Accessibility Code and the ADA.
5. E.
   Parking Stall and Aisle Dimensions.

   1. 1.
      Standard Parking Stall and Aisle Dimensions. Standard parking spaces, including interlocking standard parking spaces, shall comply with the minimum dimensional and layout requirements specified in Table 10-5-1(E)(1) and as generally illustrated in Figure 5.1.

1.  
   2. 2.
      Compact Parking and Motorcycle Stall and Aisle Dimensions.

      1. a.
         Compact parking stalls and aisles shall comply with the minimum dimensional and layout requirements specified in Table 10-5-1(E)(2).
      2. b.
         In parking areas containing more than ten (10) spaces, up to five (5) percent of the spaces exceeding the first ten (10) spaces may be designed for compact vehicles.
      3. c.
         Compact parking spaces shall be labeled for such purposes.
      4. d.
         Compact parking stalls shall be grouped together and separated from standard parking stalls. Striping of at least one half (1/2) foot in width shall be used to visually delineate the edge of the area used for compact vehicle parking spaces from standards parking stalls.

Figure 5.1. Dimensional Requirements of Parking Spaces and Drive Aisles

6. F.
   Access and Cross Access.

   1. 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. 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:

      1. 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 multi-family, nonresidential, or mixed-use development, or to the boundary of adjoining vacant land zoned to allow multi-family, nonresidential, or mixed-use development.
      2. 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.
      3. 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.
      4. 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.

All required parking spaces shall be within one thousand (1,000) feet of the use served, except for spaces accessory to dwelling units (except those located in a hotel) which shall be within three hundred (300) feet of the use served. However, no parking spaces accessory to a use in a business or manufacturing district shall be located in a residence district unless authorized by the Planning and Zoning Commission in accordance with this title.
8. H.
   Off-Street Parking Requirements. 

   1. 1.
      Minimum Requirements. Except as otherwise expressly stated, off-street parking spaces shall be provided in accordance with the parking ratio requirements established in Table 10-5-1(H)(5) Minimum Parking Requirements. Parking spaces reserved for specific user groups, other than ADA compliant spaces and spaces with electric vehicle charging stations, shall not count towards the minimum requirement.
   2. 2.
      Maximum Requirements. To minimize excessive areas of pavement, no off-street parking area for nonresidential or multi-family uses shall exceed the required minimum number of parking spaces by more than twenty (20) percent, except as approved by the Zoning Administrator. In approving additional spaces, the Zoning Administrator shall determine that the parking is needed based on documented evidence of actual use and demand provided by the applicant.
   3. 3.
      Parking in the B-2 District. Nonresidential uses in the B-2 Mixed Use District shall be exempted from providing off-street parking as required in the form-based code.

         Fractions. When measurements of the number of required spaces result in a fractional number, the fraction shall be rounded up to the next highest whole number.
      2. b.
         Area Measurements. Unless otherwise expressly stated, all area-based (square footage) parking standards must be computed on the basis of net floor area (NFA) as defined in Section 10-2-6(L) of this ordinance.
   5. 5.
      Unlisted Uses. In the case of uses not listed in Table 10-5-1(H)(5) Minimum Parking Requirements, the number of spaces for a similar use, as determined by the Zoning Administrator, shall apply.

9. I.
   Fee-In-Lieu of Off-Street Parking. An applicant may request to pay a fee-in-lieu of the off-street parking required in this Section. The City will allocate the fee to construct and maintain public parking facilities.

   1. 1.
      All requests for a fee-in-lieu of off-street parking shall be subject to approval by the City Council. A maximum of twenty (20) percent of the off-street parking required in this subsection may be substituted for the provision of a fee-in-lieu of parking.
   2. 2.

   3. 3.
      An approved payment in lieu of providing parking shall be paid prior to issuance of a building permit.
10. J.
    Reserved Parking Spaces. 

    1. 1.
       Curb-Side Pickup.

       1. a.
          A maximum of five (5) percent of required parking spaces specified in Table 10-5-1(H)(5) may be reserved for curb-side pickup patrons.
       2. b.
          Parking spaces reserved for curb-side pickup patrons shall be located either to the side of the principal building, in the rear of the parking lot, away from main building entrances so as not to inhibit pedestrian travel between the principal building entrance and off-street parking areas, near employee exits or in another location approved by the Zoning Administrator.
       3. c.
          The Zoning Administrator may reduce the minimum number of parking spots required by one (1) space per parking spot reserved for curbside pickup patrons.
    2. 2.

    1. 1.
       Quantity Required. Any parking structure, parking area serving a multi-family use, or any parking area with fifty (50) or more parking spaces, shall install the infrastructure required to accommodate a minimum of one (1) electric vehicle charging station per every fifty (50) parking spaces. 
    2. 2.
       Measurement. The number of electric vehicle charging stations required shall be determined based on the number of vehicle spaces provided that allow for electric vehicle charging. Double counting by using dual chargers per a single station but not providing the required number of vehicle spaces shall be prohibited.
12. L.
    Allowed Reductions to Required Parking. Table 10-5-1(L) establishes reductions to required parking that may be approved by the Zoning Administrator. 

13. M.
    Shared Parking.

    1. 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. 2.
       The ability to share spaces is the result of two (2) conditions:

       1. a.
          Vehicles accumulate at different times; either by hours, days, or seasons.
       2. b.
          Relationship of the uses allows for multiple visits in one (1) auto trip.
    3. 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.

       1. a.
          For purposes of this Section, the following uses are considered daytime uses:

          1. (1)
             Office Uses,
          2. (2)
             Commercial Service Uses,
          3. (3)
             Commercial Retail Uses,
          4. (4)
             Industrial Uses, and
          5. (5)
             Other similar primarily daytime uses, as determined by the City Council.
       2. b.
          For purposes of this Section, the following uses are considered evening or weekend uses:

          1. (1)
             Physical Health and Entertainment Uses,
          2. (2)
             Public/Semi-Public Uses,
          3. (3)
             Eating and Drinking Uses, and
          4. (4)
             Other similar primarily nighttime or weekend uses, as determined by the City Council.
    4. 4.
       Standards.

       1. 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.
       2. 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. (1)
             Adequate lighting.
          2. (2)
             Separation from the right-of-way.
          3. (3)
             Legal crosswalks for right-of-way crossing.
          4. (4)
             Asphalt, concrete, or similar surface material.
       3. 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.
14. N.
    Pedestrian Circulation Standards.

    1. 1.
       Off-street parking areas shall include on-site pedestrian circulation systems to ensure the safety of pedestrians, bicyclists, and motorists.
    2. 2.
       The on-site pedestrian circulation system shall comply with all ADA standards.
    3. 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. 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. 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. 6.
       Connections to existing and future planned trails shall be provided.
15. 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. 1.
       Types of Parking. The following types of bicycle parking shall be allowed:

       1. a.
          Short-Term Parking.

          1. (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. (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.
       2. b.
          Long-Term Parking.

          1. (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. (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. 2.
       Off-Street Parking Reduction For Bicycle Parking. 

       1. 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. (1)
             No fee is required for using the bicycle parking made available;
          2. (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.
       2. 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.
       3. c.
          This provision is applicable to all land uses except single-family residential and duplex residential.
16. 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. 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. 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 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. 3.
       Termination of Land Bank.

       1. 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. (1)
             The intensity of the use is increased,
          2. (2)
             The type of use changes,
          3. (3)
             There is an addition to the property or building.
       2. 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.
17. Q.
    Off-Street Loading Regulations and Requirements.

    1. 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).

    5. 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. 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. 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.

Landscape required by this section shall be in addition to landscape required under other sections of this title. 

   1. 1.
      Applicability. Transition zone landscaping is required as follows:

      1. a.
         The construction or installation of any new primary building or primary use; and
      2. b.
         The expansion of any existing primary building or primary use that results in an increase in gross floor area by more than five (5) percent or one thousand (1,000) square feet, whichever is greater. In the case of expansions that trigger compliance with transition zone requirements, transition zone landscaping is required only in proportion to the degree of expansion. The Zoning Administrator is authorized to allow the transition zone to be established adjacent to the area of expansion or to disperse transition zone landscaping along the entire site transition zone.
   2. 2.
      Application of Transition Zone Types. Transition zones shall be provided based on Table 10-5-3(F)(2), except where adjacent uses are of a similar nature, scale, and intensity as determined by the Zoning Administrator. As per Table 10-5-3(F)(2), the type of required transition zone is dependent upon the land use type of the subject lot and the land use type of the adjacent lot(s).

1.  
   3. 3.
      Transition Zone Types. Four (4) transition zone types are established in recognition of the different contexts that may exist, as shown in Table 10-5-3(F)(3). Transition zones may include a combination of elements including setback distances for separation, planting types, solid fencing, green walls, vegetated stormwater management areas, living groundcover, or turf.

      1. a.
         Critical areas such as floodplains, steep slopes, and wetlands, should be left in their natural condition or only partially cleared.
      2. b.
         Roadways, storage areas, and parking lots should be located away from valuable tree stands.
      3. c.
         Cutting and filling in the vicinity of valuable trees should be minimal.
      4. d.
         If more than one-third of the tree’s root zone is to be affected by construction, the tree should be part of the removal plan and replaced with the appropriate number of trees.
   2. 2.
      Tree Survey Requirements. Every tree survey for any new development shall include the following:

      1. a.
         Location, species (botanic and common name), and diameter at breast height (DBH) of all trees four (4) inches DBH or larger.
      2. b.
         Survey must clearly identify which trees are proposed to be removed and which are proposed to be preserved.
      3. c.
         A summary data table indicating total number of trees removed and trees to be replaced shall be provided on the survey.
   3. 3.

      4. d.
         If the tree(s) approved for removal is (are) dead from natural causes prior to the date of the tree removal permit, then no replacement tree(s) are required for them.

   4. 4.
      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.
   5. 5.
      Fee in Lieu. A fee may be provided in lieu of the replacement of trees or preservation of existing trees as established in the City of Yorkville’s adopted ordinances. These fees will be based upon wholesale pricing for a two and a half (2 ½) to three (3) inch tree and shall cover the cost of the tree and the estimated cost of the installation of the trees required to be planted. Money collected from the fee in lieu option shall be deposited into a Tree Bank Fund to be used towards tree replacement and plantings throughout the City.
   6. 6.
      Tree Preservation Plan. Development on all parcels four (4) acres or greater in area shall require the submittal and approval of a tree removal plan.

   3. 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. 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).
2. B.
   Exceptions. The provisions of this Code shall not apply to:

   1. 1.
      Industrial accessory structures. However, all accessory structures should complement the main structure.

3. C.
   Criteria for Appearance.

   1. 1.
      General. Creativity and ingenuity in applying the standards and guidelines listed in this Code are encouraged. Likewise, ingenuity and creativity, while considering deviations to the standards and guidelines of this Code, are encouraged.
   2. 2.
      Residential.

      1. a.
         Single-Family Detached and Duplexes. Shall be as specified in the Anti-Monotony standards in Section 10-7-8.
      2. b.
         Single-Family Attached and Multiple-Family. The intent of this chapter, specifically pertaining to single-family attached and multi-family buildings, is to create a "sense of community". This can be achieved through careful site planning as well as thoughtful building design and color selections.

         1. (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:

            1. (a)
               Siding;
            2. (b)
               Masonry;
            3. (c)
               Roof;
            4. (d)
               Paint/stain;
            5. (e)
               Doors.
         2. (2)
            Sites where requested setbacks and yards are less than the minimum zoning district requirements must provide an interesting relationship between buildings.
         3. (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. (4)
            The height and scale of each building shall be compatible with its site and adjoining buildings.
         5. (5)
            Newly installed utility services, and service revisions necessitated by exterior alterations, shall be underground.
         6. (6)
            The architectural character of the building shall be in keeping with the topographical dictates of the site.
         7. (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.

            1. (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. (8)
            Pedestrian features/amenities, such as covered walkways, street furniture, and bicycle rack facilities are encouraged.
         9. (9)
            Common open space and outdoor features are encouraged.

      Industrial Uses.

      1. a.
         Guidelines.

         1. (1)
            Masonry products or precast concrete shall be incorporated on at least fifty (50) percent of the total building, as broken down as follows: The "front facade" (defined as that facade that faces a street that includes a main entry to the building) shall itself incorporate masonry products or precast concrete on at least fifty (50) percent of the facade. Any other facade that abuts a street shall incorporate masonry products or precast concrete. The use of masonry products or precast concrete is encouraged on the remaining facades. Where precast concrete panels or split face block is utilized, the use of colors, patterns, or other architectural features within these panels/blocks is encouraged.
         2. (2)
