RE-B
Residential Estate Zone
The RE zone is applied to areas of the City appropriate for very low density residential land uses, at densities of 0.2 to 3.0 units per acre, compatible with the topography and public service capacities. The specific allowable density for each parcel is shown on the Zoning Map by a numerical suffix residential density designator (see Section D2-8). Minimum lot size for new parcels ranges from 15,000 to 20,000 sq ft. The RE zone is consistent with and implements the Single Family Low Density land use classification of the General Plan.
