1.

Application referral. Applications for discretionary land use permits, land divisions or General Plan amendments within the planning impact areas for the cities of Grover Beach and Arroyo Grande shall be referred by the County to the appropriate city or cities for review and comment.

Figure 98-8: Planning Impact Areas "A" and "B"

B.

Circulation standards.

1.

Areawide systems - Conditional Use Permit projects. Projects requiring. Conditional Use Permit approval shall be integrated into areawide circulation and utility easements, providing for future extensions into adjacent undeveloped properties wherever feasible or where known areawide rights-of-way are planned.

2.

Driveways - New land divisions. Where possible, new land divisions shall be designed to combining driveways and private access roads serving proposed parcels wherever terrain and adequate sight distance on the public road allow.

3.

Pedestrian and bikeways - New land divisions. Provide for safe and site-sensitive pedestrian and bike circulation facilities in the design of roads for new subdivisions where feasible.

4.

Road design and construction - New land divisions.

a.

Site disturbance. Road alignments proposed in new land division applications shall be designed and constructed to minimize terrain disturbance consistent with safety and construction cost. Altered slopes shall be replanted with indigenous plants or protected by other appropriate erosion control measures.

b.

Circulation. New land divisions adjacent to the city limits of an incorporated city shall be designed to include offers-to-dedicate for roads connecting with the city such that the street right-of-way widths will reasonably correspond to those required under City standards. Appropriate transitions in road improvements shall be provided between City and County roads adjacent to the City limits. In addition, logical existing or future street connections to City streets shall be provided to encourage an efficient circulation system.

C.

Site planning on sloping sites - Conditional Use Permit projects. Projects requiring Conditional Use Permit approval on sites with varied terrain shall include design provisions for concentrating developments on moderate slopes, retaining steeper slopes visible from public roads undeveloped.

D.

Utility Services - Undergrounding requirement for Conditional Use Permit projects. All projects requiring Conditional Use Permit approval shall provide for utilities being placed underground unless the Commission determines either that: the proposed development will be of low intensity or in an isolated location; or that supporting overhead utilities will not be visible from public roads; or that overriding operational, economic or site conditions of the project warrant waiver of this requirement.

E.

Arroyo Grande and Cienega Valleys - Limitation on use. Within the Arroyo Grande and Cienaga Valleys (see Figure 98-10), land uses shall be limited to the following in compliance with the land use permit requirements of Section 22.06.030: agricultural accessory structure; crop production and grazing; animal keeping; farm support quarters; single-family dwellings; mobile homes; temporary dwellings; roadside stands; outdoor retail sales; public safety facilities; pipelines and transmission lines.
