R1A
One-Acre Residential Zone
The R1A, One-acre Residential Zone, is used to create a more dispersed suburban residential character to an area by providing for and regulating medium density residential development at the highest range of one dwelling unit per acre. Accessory structures and uses and low-intensity commercial agricultural pursuits (crop lands, orchards, raising and grazing of domestic farm animals) are considered compatible with this zone. This zone is applicable to lands designated as Medium Density Residential (MDR) in the General Plan and may be applied to High Density Residential lands where infrastructure to serve higher densities is not yet available.
