Low Density residential areas include standard suburban subdivisions, and parcels with agricultural uses (such as crop production, animal keeping, beekeeping and pasture areas) .  Low Density Residential areas include existing neighborhoods with a base density of 1 to 3.5 units per acre.  As a standard single family residential subdivision, R-S zoning with an average lot size of 15,000 s.f. may apply, or R-1-10 zoning with a minimum lot size of 10,000 s.f. may also apply.  East of Highway 89 along the mountain bench, lower density is most compatible where slopes and sensitive lands are prevalent, infrastructure services are limited, and native vegetation presents a higher risk for an urban wildland fire hazard.   In these areas, development opportunities may be limited given the physical constraints for providing services, and the goal to prevent urban wild-land risk related to wildfire, slope failure and fault lines.  The area south of the APZ may require a limited residential density based on the findings and recommendations of a Joint Land Use Study with Hill Air Force Base.
