Chapter 17.20 — OVERLAY ZONING DISTRICTS

The overlay zoning districts established by this Chapter provide guidance for development and new land uses in addition to the standards and regulations of the primary zoning districts, where important site, neighborhood, or compatibility issues require particular attention in project planning.

The applicability of any overlay zoning district to specific sites is shown by the overlay Zoning Map symbol established by Section 17.06.020 (Zoning Districts Established), being appended as a suffix to the symbol for the primary zoning district on the Zoning Map (for example, RSF (pd)). The provisions of this Chapter apply to proposed land uses and development in addition to all other applicable requirements of this Development Code. In the event of any perceived conflict between the provisions of this Chapter and any other provision of this Development Code, this Chapter shall control.

• A. Purpose. The Planned Development (pd) Overlay is intended to encourage planned developments with a mixture of land uses including different densities of residential units, professional office uses, commercial uses, and public and recreational uses.

• B. Applicability. The (pd) overlay is applied to lands that are presently largely undeveloped where planned unit developments or neighborhood developments are encouraged. The (pd) overlay may be combined with any residential, commercial, manufacturing/industrial, or special purpose zoning district established by Section 17.06.020 (Zoning Districts Established). The (pd) overlay is established and shown on the Zoning Map.

• C. Allowed land uses and development standards. Any land use normally allowed in the primary zoning district by this article may be allowed within the (pd) overlay subject to compliance with

all applicable requirements of the primary zoning district, and all other applicable provisions of this Development Code.

• D. Permit requirements. Development and new land uses designated with a (pd) overlay shall require the Planning Commission approval of development plans that show how projects in these areas will conform to all general plan goals, policies, objectives and design guidelines.

• A. Purpose. The Creek/Floodplain (cf) Overlay is intended for those areas of the City adjacent to the Jackson Creek or a tributary thereof where sensitivity and special attention is required in project design, including but not limited to setbacks from the creek, preservation of public access to the river corridor, and protection of natural environmental features such as riparian vegetation, wetlands, and wildlife habitat. The (cf) overlay area is delineated on the Federal Emergency Management Agency Flood Insurance Rate Map for the City of Jackson.

• B. Applicability. The (cf) overlay may be combined with any residential, commercial, manufacturing/industrial, or special purpose zoning district established by Section 17.06.020 (Zoning Districts Established).

• C. Allowed land uses and permit requirements. Any land use normally allowed as a permitted or conditional use in the primary zoning district by this article may be allowed within the (cf) overlay subject to the development standards.

• D. Development standards. Proposed development and new land uses within the (cf) overlay shall comply with the development standards of the primary zoning district, all other applicable provisions of this Development Code, and the following requirements:

  1. Setback requirements. Proposed development shall be set back from the Jackson Creek or any tributary thereof 100 year floodplain based on the unique topographic features of each site within the (cf) overlay zone. Specific setbacks shall be established through the project approval process.

  2. Allowed uses within required setbacks. The following uses are allowed within the setback areas required by subsection D.1:

     • a. Paved or unpaved bike lanes and pedestrian/equestrian paths;

     • b. Nature preserve; and

     • c. Picnic tables.

  3. Revegetation requirements. In order to prevent bank erosion and restore wildlife habitat, a riparian revegetation program shall be required prior to approval of a new development project on property where past development practices have resulted in removal of most or all riparian vegetation from the creek bank. The riparian vegetation program shall be prepared by a qualified biologist or landscape architect, who shall determine the appropriate mix and density of species to restore wildlife values over time and protect from bank erosion.

• A. Purpose. The creation of the Visual Corridor (vc) Overlay is to protect the scenic views enjoyed by everyone as they enter the City of Jackson from both the north and south of town.

• B. Applicability. The (vc) overlay may be combined with any residential, commercial, manufacturing/industrial, or special purpose zoning district established by Section 17.06.020 (Zoning Districts Established). The (vc) overlay is established, and shall be applied and shown on the Visual Corridor Map to those areas of the City with scenic views.

• C. Allowed land uses. Any land use normally allowed as a permitted use in the primary zoning district by Tables 2-3, 2-5, or 2-7 (Allowable Land Uses and Permit Requirements) may be allowed within the (vc) overlay zoning district. Land uses identified by Tables 2-3, 2-5, or 2-7 that require a conditional use permit shall be prohibited within the (vc) overlay district.

• D. Permit requirements. Development and new land uses within the (vc) overlay district shall obtain the land use permit required by this article for the primary zoning district.

• E. Development standards. Proposed development and new land uses within the (vc) overlay zoning district shall comply with the development standards of the primary zoning district, all other applicable provisions of this Development Code, any conditions of approval providing measures to preserve and protect existing resources, and the following requirements:

  1. The architectural style of structures within the (vc) overlay shall be compatible with historic structures in the Jackson area.

  2. The height of structures within the (vc) overlay shall not block the surrounding view shed's points of interest (including but not limited to the Kennedy Wheels, the Serbian Orthodox Church, and the Kennedy Mine structures).

  3. Development within the (vc) overlay shall be clustered near roads (with appropriate setbacks) as much as feasible. This would maximize the amount of open space within the corridor.

  4. Development within the (vc) overlay shall be landscaped to minimize all structures' visual impact to the greatest extent possible.

• A. Purpose. The Historic Corridor (hc) overlay is intended to safeguard the City's unique cultural heritage as embodied and reflected in the City's architectural history and patterns of cultural development; to preserve diverse architectural styles, patterns of development, and design preferences reflecting phases of the City's history; to protect and enhance the City's attraction to tourists and visitors thereby stimulating business and industry; to identify as early as possible and resolve conflicts between the preservation of cultural resources and alternative land uses; to integrate the preservation of cultural resources into public and private land use management and development processes. Development standards for this district address new development, alterations and modifications to existing buildings and structures, demolition of historic buildings and structures, and the identification and protection of subsurface historic and archaeological resources.

• B. Applicability. The (hc) overlay may be combined with any residential, commercial, manufacturing/industrial, or special purpose zoning district established by Section 17.06.020 (Zoning Districts Established). The (hc) overlay is established, and shall be applied and shown on the Historic Corridor Map to those areas of the City with concentrations of historic buildings and structures that contribute to the City's historic character.

• C. Allowed land uses. Any land use normally allowed in the primary zoning district may be allowed with-in the (hc) overlay.

• D. Permit requirements. Proposed development and new land uses within the Historic Corridor (hc) Overlay shall obtain the land use permits required by this article for the primary zoning district.

• E. Development standards. Proposed development and new land uses within the (hc) overlay shall comply with all applicable requirements of the primary zoning district, all other applicable provisions of this Development Code, and the applicable requirements of Chapter 17.26 (Historic Preservation Design Guidelines). Additionally, new construction or redevelopment within the Historic Corridor shall be consistent with the late nineteenth century character of the Jackson area and shall meet the following criteria:

  1. Reconstruction shall utilize same building footprint for structures built prior to 1940 unless a Conditional Use Permit is obtained by the Planning Commission.

  2. Design of redeveloped structures within the (hc) overlay shall be consistent with original historic structure.

• F. Demolition or destruction. No historic resource, or portion thereof, shall be relocated, moved, torn down, or demolished, except in compliance with the requirements of Chapter 17.83 (Demolition Review).

• G. Duty to keep in good repair. The owner, occupant, or other person in charge of an historic resource or an improvement, building, or structure in the (hc) overlay shall keep in good repair all of the exterior portions of such improvement, building, or structure, and all interior portions thereof whose maintenance is necessary to prevent deterioration and decay of any exterior architectural feature. All such improvements, buildings, or structures shall be preserved against such decay and be kept free from such structural defects through the prompt repair of any of the following:

  1. Facades and respective architectural elements which may fall and injure members of the public and property;

  2. Deteriorated or inadequate foundation, defective or deteriorated flooring or floor supports, deteriorated walls or other vertical structural supports;

  3. Members of ceilings, roofs, ceiling and roof supports, or other horizontal members which age, split, or buckle due to defective material or deterioration;

  4. Deteriorated or ineffective waterproofing of exterior walls, roofs, foundations, or floors, including broken windows or doors;

  5. Defective or insufficient weather protection for exterior wall covering, including lack of paint or weathering due to lack of paint or other protective covering; and

  6. Any fault or defect in the building which renders it not properly watertight or structurally unsafe.
