This article lists the land uses that may be allowed within the agriculture and residential zoning districts established by Section 9-3.102 (Zoning Districts), determines the type of planning permit/approval required for each use, and provides basic lot size and development standards for specific zones.
(Ord. 602 § 2, 2016)
The purposes of the individual agriculture and residential zoning
districts and the manner in which they are applied are as follows:
(a)
A
(Agriculture) Zoning District. This zone is established to protect,
preserve and encourage agriculture on suitable land. The Agriculture
Zone is intended to support and encourage the continuation of the
Agricultural Preserve Program and the maintenance of productive open
space.
(b)
RS
(Residential Suburban) Zoning District. This zone is established to
provide for large lot residential uses in areas outside the urban
services line or in other areas where large lots are desirable to
protect land uses and buildings subject to inundation, steep slopes
or other hazards.
(c)
RSF
(Residential Zoning Family) Zoning District. This zone is established
to provide for single-family residential areas within the urban services
line.
(d)
LSF
(Limited Single-Family) Zoning District. This zone is established
to provide for single-family residential areas within the urban services
line where the raising of farm animals would not be allowable.
(e)
RMF
(Residential Multifamily) Zoning District. This zone is established
to provide for apartment, condominium, townhouse development, and
other small lot residential products, where higher density residential
development is desired within the urban services line.
(Ord. 602 § 2, 2016)
Table 3-1 identifies the uses of land allowed this Zoning Code
in each agriculture and residential district, and the planning permit
required to establish each use, in compliance with Section 9-1 and
Section 9-2 of this code. Where the last column in the tables ("Specific
Use Regulations") includes a section number, the regulations in the
referenced section apply to the use. Provisions in other sections
of this article may also apply.
