Chapter 17.20 R-1 AND R-2--RESIDENTIAL USE DISTRICTS

There are three zone classification districts established for the city, plus two floating zones. The principal zones are: R-1 single-family or low density residential; R-2 two-family or medium density residential; and R-3 multiple-family or high density residential. The R-3 high density residential zone is created in order to reduce possible use conflicts resulting from different housing types and subsequent life styles. The two floating zones titled large-lot and small-lot are not placed in any one specific location as are the R-1, R-2 and R-3 principal zones. A floating zone use is applicable anywhere within a designated principal zone; however, the use identified must comply with the main objective of the underlying principal zone. For example, the agriculture activities within the city limits, that would otherwise be prohibited, must have a minimum of three acres available for agriculture use. Thus, the large-lot zone addresses both lot size and uses and therefore cannot be located in either the R-2 or R-3 zones. These zones are designed to provide for higher density housing, such as duplexes and apartments. However, the small-lot single-family residential zone can be located in any of the three residential zones because single-family housing is allowed in all three zones. In the case of the small-lot zone, it is the lot size, not the use, that is the governing factor.
These zone classifications are established, in order to permit a variety of housing and population densities with minimum conflict. Protection is provided against hazards, objectionable influences, traffic and building congestion, undue strain on municipal services, and lack of light, air and privacy. Certain essential and compatible public service facilities and institutions are permitted in these districts. (Ord. 944 § 3(A), 1996: Ord. 491 § 4.01, 1966).

The following uses are permitted in the R-1 district:
A. Single-family dwellings and their customary uses;
B. Churches, community clubhouses, noncommercial art galleries, libraries, museums, schools and parks;
C. Single-family dwellings and their customary uses on small lots (as infill), subject to the lot owner obtaining the necessary site plan approval in conformance with Section 17.23.050 of this title;
