Key to Zoning District Symbols

RA	Residential Agricultural	RS	Single-Family Residential
RE	Residential Estate	RM	Medium Density Residential
RR	Rural Residential	RH	High Density Residential

Notes:

(1) See Division 8 for land use definitions.

(2) Zoning clearance not required if the use complies with all other applicable town approval requirements and standards.

(3) Solid walls in setback areas are discouraged in Loomis. A minor use permit for a maximum six-foot tall wall for a home existing as of May 2008 may be approved by the planning commission if they can find that a sound/solid wall is the only feasible alternative. Noise measurements (to be taken from the interior of the residence with windows closed) will be required with the application and reviewed in accordance with Table 3-3, Noise Standards for Short-Duration Events Near Residential Areas (13.30.070). Design must be compatible with the neighborhood and character of Loomis as determined by the planning commission.

(4) Supportive and transitional housing shall be subject only to those restrictions that apply to other residential dwellings of the same type (e.g., single-family, multifamily) in the same zone.

(5) See 13.24.020(G) for RH-20 zone district.

(6) Property zoned RM or RH may be used to support commercial activity along Sierra College Boulevard between the town limits and Brace Road if: (a) the RM or RH property is adjacent to the commercially zoned property; (b) the commercially zoned property is immediately adjacent to Sierra College Boulevard; (c) the RM or RH property and the adjacent commercial property are under common ownership; (d) use of the RM or RH property is limited to supporting uses such as commercial parking, commercial or emergency driveways or drive aisles, lighting and landscaping; and (e) no buildings are built on the RM or RH property. In the case of such use, the development standards applicable to the RM or RH property shall be those governing development of the adjacent commercial property.
