City of Santa Rosa, CA SPECIAL PURPOSE ZONING DISTRICTS

§ 20-26.010 Purpose.

This Chapter lists the land uses that may be allowed within the Special Purpose zoning districts established by Section 20-20.020 (Zoning Map and Zoning Districts), determines the type of land use permit/approval required for each use, and provides basic standards for site layout and building size.

(Ord. 3677 § 1, 2004)

§ 20-26.020 Purposes of special purpose districts.

The purposes of the individual Special Purpose zoning districts and the manner in which they are applied are as follows.

OSR (Open Space—Recreation) district. The OSR zoning district is applied to public park and recreation sites and areas within the City. The OSR zoning district is consistent with and implements the Parks & Recreation land use classification of the General Plan.

OSC (Open Space—Conservation) district. The OSC zoning district is applied to important open space areas of the City including wetlands, waterways, hillsides, ridgelines, scenic areas, significant vegetation areas, wildlife habitat and corridors, community separators, watersheds, geologic features, natural hazards areas, agricultural land, and areas that functionally link open space areas. The OSC zoning district is consistent with and implements the Open Space land use classification of the General Plan. More specific purposes of the open space District are to:

Provide a zoning district for permanently protected open space areas;

Preserve as open space parcels from which development potential has been sold, transferred, dedicated, donated, or otherwise removed from the parcel as recorded on deed, map, development plan, policy statement, easement, private covenant, or any other legal mechanism;

Provide for limited development up to one unit per 40 acres or legally existing parcel in a manner that will preserve and maintain open space benefits;

Protect rare, threatened, and endangered plants and animals;

Protect and enhance wildlife habitat;

Provide sites for education and scientific research;

Control alteration of the natural environment and terrain in areas of environmental and scenic significance to the community;

Protect people and property from geologic, hydrologic, and other natural hazards;

Enhance and maintain for public welfare and well-being, the public amenities accrued from the preservation of scenic beauty and environmental quality;

10.

Provide opportunities for low intensity uses and recreational activities compatible with open space benefits, which may include bird watching, playing fields for team sports, nature photography and study, wildlife observation, and scientific research and education.

PI (Public and Institutional) district. The PI zoning district is applied to areas appropriate for public facilities, utilities, hospitals, and public assembly facilities including: public schools, libraries, government offices, etc. The PI zoning district is consistent with and implements the Public/Institutional land use designation of the General Plan.

PD (Planned Development) district. The PD district is intended to recognize the advantage that integrated community offers over conventional zoning techniques in implementing General Plan goals through specific site developments. The PD district is specifically envisioned as a mechanism to preserve and/or create distinctive, high quality, single or mixed use developments that meet or exceed the goals of the General Plan. The requirements of this district are intended to encourage preservation of existing amenities and creation of new amenities; provide for a variety of housing types and densities; and achieve superior relationships among uses, both within and surrounding the district. The PD district is intended to be used only where the other zoning districts established by this Zoning Code cannot achieve these goals.

(Ord. 3677 § 1, 2004; Ord. 4002 § 7, 2012)

§ 20-26.030 Special purpose district land uses and permit requirements.

Special Purpose districts except PD. Table 2-12 identifies the uses of land allowed by this Zoning Code in the Special Purpose zoning districts except for the PD district, and the land use permit required to establish each use, in compliance with Section 20-21.030 (Allowable Land Uses and Permit Requirements).

Note: where the last column in the table ("Specific Use Regulations") includes a section number, the regulations in the referenced section apply to the use. Provisions in other sections of this Zoning Code may also apply.

Where a Policy Statement or Development Plan does not include a list of allowable land uses, the most similar standard zoning district and its list of allowable land uses shall apply.

Land use permit requirements. The adopted Policy Statement or Development Plan shall specify whether each allowable use is permitted, or requires Minor Use Permit, or Conditional Use Permit approval; except that the re-occupancy of an existing building with a use permitted in the Policy Statement or Development Plan that is similar or less intense than the previous approved use of the building shall be permitted, as determined by the Director. The Director's determination shall be based on criteria including the following:

Pedestrian and vehicular traffic;

Parking requirements;

Number of employees/clients;

Nuisance factors including noise, odors, fumes, dust, dirt, litter, vibrations, etc.; and

Setback requirements. Unless specifically stated in the Policy Statement or Development Plan, single-family dwellings shall comply with the following setback requirements.

Front yard setback: 15 feet, except that garages and carports opening onto a street shall have a minimum distance of 19 feet between the opening and the rear of a public sidewalk or 19 feet from property line or adopted plan line, whichever is greater, except that detached accessory buildings shall have a 50-foot front yard.

Side yard setback: five feet, except that:

(1)

Two story portions of the structure shall be set back 10 feet; and

Rear yard setback: five feet.

Allowable variation of standards with rezoning to PD. In considering a proposed Development Plan and Policy Statement, the Commission and Council may require higher standards or allow different standards for the PD district than are required by other residential zoning districts with respect to density, uses, heights, parking, traffic circulation, landscaping, lot sizes, and other standards, provided that the modified standards, requirements and regulations are consistent with the General Plan.

Minor modifications. Minor modifications to an approved PD project that do not increase approved density, change approved uses, or substantially change the approved Policy Statement or Development Plan may be authorized through Minor Use Permit approval.
