This chapter shall be entitled "RM-900A and RM-900B Residential: Multifamily Zone."
(Ord. 1591 § 200, 2014)
The principal objective and purpose of the Zones in this chapter and their application is to establish areas permitting the maximum population density in the RM-900A Zone for apartment use only, and permit uses other than apartment residential, such as medical, dental, and social services and shelter, all for human beings in the RM-900B Zone for restricted services only. The uses permitted in the RM-900B Zones relate conveniently and consistently in terms of traffic generated, demands upon public service facilities, and impact upon each other. A related consideration is to make it possible to more efficiently and economically design and install all physical public service facilities in terms of size and capacity to adequately and permanently meet needs resulting from a defined intensity of land use.
