Zoning

R-P

Planned Residential District

The purpose of this chapter is to effect the development of attractive residential properties in keeping with the character of the community with minimum disturbance to the quality of the neighborhoods and of the natural features of the landscape by requiring the approval of specific plans showing site design and overall design character prior to development.; In establishing R-P districts, the City of Mill Valley intends to make possible development in which the size and shape of buildings, building heights, and the open spaces surrounding buildings or groups of buildings may be varied. Density shall be set at a level or range of dwelling units which is consistent with limitations imposed by on-site, natural resource, topographic and geologic conditions and by the level of public services and road access that can be reasonably provided. The development approval process for R-P districts is intended to allow for continuous refinement of the permitted density as additional information is acquired regarding the capacity of the land.
