A. Site Design Standards: Housing should foster a sense of neighborhood among nearby residents and a sense of community through linkage with surrounding neighborhoods.
1. All new residential developments (subdivisions) shall be subject to all requirements set forth in the Parker subdivision ordinance.
2. All new residential development (subdivisions) shall include a pedestrian and bicycle multiuse pathway as part of the required open space which shall be designed, located and oriented to provide: a) high pedestrian and bicycle accessibility within and around the development; b) connections to adjacent developments to enhance a structure of continuous open space throughout the community; and c) a buffer between less developed, less densely developed lands and urban development patterns.
3. New development (subdivisions) adjacent to rural residential, or less developed land uses must provide a landscaped open space buffer of sufficient width inward from the property line, with the open space buffer oriented and designed in a manner to connect to the open space, pedestrian and trail systems within the development and those in adjoining developments.
4. The use of alleyways with rear garage configurations, entry access points, and adjacent vehicular parking areas is encouraged and may be considered as a primary means of access to a residential lot.
5. Developments containing alleyways shall plan and design the alleyways as a secure pedestrianway that links to the neighborhood pedestrian and bicycle multiuse pathways and open space system.
6. The residential structure should have a strong relationship to the neighborhood street. A walkway from the street to the front entry is strongly encouraged.
B. Open Space Standards:
1. All residential developments (subdivisions) shall provide a minimum fifteen percent (15%) net acreage as open space or as required by the Parker subdivision ordinance, whichever is greater. "Net acres" shall be defined as the total acres exclusive of the area required for arterial or collector street right of way dedications, any commercial or industrial lands, and school/public site reservations.
2. Not more than fifty percent (50%) of the required open space for any residential development (subdivisions) shall be attributed to golf course use or ancillary golf uses.
3. Private (subdivision) open space areas should be designated as a tract, which is owned and maintained by a homeowners' association.
4. If the open space area (subdivision) is to be dedicated for public use it shall be located to provide access and physical connections to adjacent neighborhoods and to the community open space network and trail system or to provide protection to adjacent public lands.
C. Architectural Requirements:
1. Mirrored surfaces or reflective treatment that changes or enhances ordinary glass into a mirrored surface is prohibited. Bright untarnished metallic surfaces, including roof materials, shall be chemically treated so they are nonreflective.
2. Paint and material colors shall have a light reflective value (LRV) no greater than forty percent (40%). Limited use of contrasting accenting colors in excess of forty percent (40%) LRV for small elements such as entryways and special architectural features of the building may be allowed.
3. Roof mounted mechanical equipment is prohibited. Mechanical equipment, propane tanks, coolers, water filters and similar utility equipment shall be installed at ground level or wall mounted and shall be screened from public view and designed to appear as an integral part of the building.
4. The residence shall have a permanent foundation and a garage or carport the design and materials of which shall be compatible with the main structure. In RR-20, RR-2.5 and R1-43 zoning districts the garage area shall not exceed thirty five percent (35%) of the front face plane of the residential structure. In R1-18, R1-10 and R1-7 the garage area shall not exceed forty five percent (45%) of the front face plane of the residential structure.
5. Detached garages and side entry garages are strongly encouraged.
6. Front porches and courtyards are strongly encouraged and should provide a pedestrian connection, other than the driveway, to the street.
7. Open gable roofs, emphasizing the lack of detail, should be avoided. Rooflines with differing heights and style combinations, stepping, or different orientations are strongly encouraged.
8. All exterior elevations of a residential structure shall provide architectural detailing, not just the front elevation.
9. Window embellishments shall be provided on all houses by adding architectural features which enhance the elevations, e.g., sturdy synthetic wood substitutes, greater variation of window design, different window styles, tile inlays and recesses, structural popouts, gabled roof features over the windows, etc. Such features must be added to all of the exterior elevations of the house to provide interest and relief.
10. All multi-story houses shall be constructed so that the vertical plane of the second floor front and rear elevation is set back a minimum distance of four feet (4') from the vertical plane of the ground floor front and rear elevation. This should also apply to the side elevations of all houses that abut an arterial street on the side.
11. All tract home developments shall have a minimum of four (4) floor plans, with a minimum of three (3) distinctly different elevations for each floor plan. Additionally, a minimum of three (3) colors of roof material, three (3) styles of garage doors and three (3) exterior paint colors shall be required to further promote visual interest and architectural diversity. The same elevations shall not be utilized across from or adjacent to each other. (Ord. 03-2005, 9-6-2005)
