The intent of the R-160 residential district is similar to that of the R-120 district. That is to maintain the existing development pattern of large estates and resulting open space. Multifamily dwellings of new construction are not permitted. The natural environment and lack of support services likewise limits development in this part of the city. The development pattern in this area consists of large tracts of land greater in extent than those found in the R-120 district. The intent of this district is to maintain that low density pattern of development which has occurred over time.
