   2. 2.
      In areas not subdivided into lots and blocks, wherever a district is indicated as a strip adjacent to and paralleling a street or highway, the depth of such strips shall be in accordance with the dimensions shown on the map measured at right angles from the centerline of the street or highway, and the length of frontage shall be in accordance with dimensions shown on the map from section, quarter sections or division lines, or centerlines of streets, highways or railroad rights of way unless otherwise indicated.

Effective on: 1/1/1901

All streets, alleys, public ways, waterways, and railroad rights-of-way, if not otherwise specifically designated, shall be deemed to be in the same zone as the property immediately abutting upon such alleys, streets, public ways, or waterways and railroad rights-of-way.

   Districts

   1. 1.
      The following districts are established for mixed use, commercial, and residential development within downtown and adjacent redevelopment areas. Figure 3.10 illustrates the locations for the districts.

      1. a.
         S1: Bridge Street District
      2. b.
         S2: Hydraulic Street District
      3. c.

Table 10-3-13(B)(1)(a) Bridge Street

Figure 3.11. Bridge Street (Long-term)

1.  
   2. 2.
      S1: Bridge Street District. The Bridge Street District may be considered the gateway into downtown Yorkville and retains potential to become the iconic stretch that helps draw people into local businesses and displays an attractive image that represents the people of Yorkville. The form of this retail and service-centered area establishes a street wall of storefront style-building facades with shallow build-to-zones along the sidewalk and parking in the rear or off-site. It focuses pedestrian-friendly retail and service uses on the ground story with office uses in upper stories.

Table 10-3-13(B)(1)(b) Hydraulic Street

Figure 3.12. Hydraulic Street (Long-term)

1.  
   3. 3.
      S2: Hydraulic Street District: The Hydraulic Street District includes complex conditions, including a tapering right-of-way that narrows from west to east and an active freight rail line that runs parallel to the street surface within the right-of-way. Hydraulic Street features short, utilitarian buildings, as well as an inoperable grain elevator, that create an eclectic mix of land uses and character. The form of this area remains pedestrian-centered but storefront-style buildings focus a broader spectrum of retail and service uses on the ground story with residential and/or office uses in upper stories.

      1. (1)
         Notes: The streetscape master plan includes a proposed slip lane on the south side of Hydraulic Street between Bridge Street and Heustis Street. This table includes dimensions for the public right-of-way section of the street.

   4. 4.
      S3: Van Emmon Street District. The Van Emmon Street District is a lower scale district. Commercial, residential, and mixed use buildings make up this district in variety of building types. A broader spectrum of retail, service, and office uses support the Bridge Street and Hydraulic Street Districts and ground floor residential is permitted. The form of this area is pedestrian-centered, but allows for more vehicular access and off-street parking options.

   5. 5.
      S4: "B" Street District. The "B" Street District is a lower scale commercial district designed to serve adjacent neighborhoods and the greater community. Flanked by the Hydraulic and Van Emmon Districts, a wider range of residential uses is permitted. As one of the main street types between primary thoroughfares, pedestrian access and safety remains a priority.

   6. 6.
      S5: "B" Street - Residential District. The "B" Street Residential District is a lower-scale residential district with a mix of townhouses and yard buildings. With a maximum height of six (6) stories under the general provision of the zoning code, this area provides for a mix of housing types adjacent to downtown for people of all ages and lifestyles.

Figure 3.16. Hierarchy of Street Types

1.  
   7. 7.
      Hierarchy of Districts. Development under this code is regulated by street type. The various street types are related to each other in a hierarchical manner. When these streets intersect, the primary street frontage is determined by its higher order in the hierarchy. The front of a building and its main entrance must face the primary street. Figure 3.16 illustrates the hierarchy of street types.
   8. 8.
      Primary Streets. The primary streets map designates primary, secondary, and tertiary streets within the downtown overlay district. These designations prioritize the street frontages for locating the front lot line for required amounts building frontage and allowable amounts of parking frontage. Refer to 3.16.

      1. a.
         Vehicular Access. Vehicular access is also managed through this street prioritization within the building type requirements (refer to Section 10-3-13(D)). See Figure 3.17 and Figure 3.18 for illustration of permitted vehicular access locations.

Figure 3.17. Secondary Street Frontage: Access Drive Permitted Location

Figure 3.18. Primary Street Frontage Only: Access Drive Permitted Location

1.  
   1.  
      1.  
         1. (1)
            The order of access is typically as follows, unless otherwise permitted by building type:

            1. (a)
               Lane (Tertiary Street) or alley (un-mapped) permits unlimited access.
            2. (b)
               If no lane or alley exists, one (1) driveway per secondary street frontage is permitted.
            3. (c)
               If no tertiary or secondary street abuts the parcel, one (1) driveway is permitted off the primary street and shared access with adjacent properties is encouraged.
         2. (2)
            Refer to the subdivision control ordinance for additional requirements of vehicular access off adjacent streets. Interparcel access requirements shall be met.
      2. b.
         Primary, Secondary, and Tertiary Street Designations.

         1. (1)
            Primary Streets. Primary streets require the most intact and continuous streetwall with few, if any, driveway access. The front lot line shall always be located on the primary street. When a parcel is fronted by more than two (2) primary streets, the Zoning Administrator shall determine which is the appropriate street for the front lot line. The determination should be based on locations of existing and other proposed development front lot lines.

            1. (a)
               Vehicular access should not be located off a primary street, unless no other options exists. Refer to Section 10-3-13(D) Building type requirements for allowances of vehicular access, if applicable.
         2. (2)
            Secondary Streets. Secondary streets are intended to have a fairly continuous streetwall,but will likely have a driveway for each parcel. If no tertiary street exists, access will likely be off the secondary street.
         3. (3)
            Tertiary Streets. Tertiary streets typically have no streetwall requirements and could be fronted by parking structures and parking lots with multiple drives and/or vehicular access points.
