Chapter 13.24 — RESIDENTIAL ZONING DISTRICTS — Loomis Zoning Code

§ 13.24.010. Purpose. ¶

This chapter lists the land uses that may be allowed within the residential zoning districts established by Section 13.20.020 , determines the type of land use permit/approval required for each use, and provides basic standards for site layout and building size. (Ord. 205 § 1 (Exh. A), 2003; Ord. 299, 11/12/2024)

§ 13.24.020. Purposes of the residential zoning districts. ¶

The purposes of the individual residential zoning districts and the manner in which they are applied are as follows.

A. RA (Residential Agricultural) Zoning District. The RA district is applied to areas appropriate for agricultural uses such as orchards, nurseries and vineyards, cattle grazing and very lowdensity residential uses, where proposed development and agricultural uses maintain existing natural vegetation and topography to the maximum extent feasible. The maximum allowable density is 4.6 acres per dwelling unit. The RA zoning district is consistent with and implements the residential agricultural land use designation of the general plan.
B. RE (Residential Estate) Zoning District. The RE district is applied to areas appropriate for large-lot single-family residential development, together with agricultural uses such as orchards, nurseries and vineyards, cattle grazing, where proposed development and agricultural uses maintain existing natural vegetation and topography to the maximum extent feasible. The maximum allowable density is 2.3 acres per dwelling unit. The RE zoning district is consistent with and implements the residential estate land use designation of the general plan.
C. RR (Rural Residential) Zoning District. The RR district is also applied to areas appropriate for large-lot single-family residential development, together with agricultural uses such as orchards and vineyards, where proposed development and agricultural uses maintain existing natural vegetation and topography to the maximum extent feasible, but where the keeping of large animals occurs only on parcels of one acre or larger. The maximum allowable density is one acre per dwelling unit. The RR zoning district is consistent with and implements the rural residential land use designation of the general plan.
D. RS (Single-Family Residential) Zoning District. The RS zoning district is applied to areas appropriate for neighborhoods of single-family homes, and related, compatible uses. The maximum allowable density ranges from one dwelling per half-acre, to two to six dwellings per acre, with the specific allowable density for each parcel shown on the zoning map by a numerical suffix to the RS map symbol (see Section 13.24.050 ). The RS-5 district is intended to be applied only within the downtown area of Loomis. The RS zoning district is consistent with and implements the residential - low density and residential - medium density land use designations of the general plan.

e, with the specific allowable density for each parcel shown on the zoning map by a numerical suffix to the RS map symbol (see Section 13.24.050 ). The RS-5 district is intended to be applied only within the downtown area of Loomis. The RS zoning district is consistent with and implements the residential - low density and residential - medium density land use designations of the general plan.

E. RM (Medium Density Residential) Zoning District. The RM zoning district is applied to areas appropriate for a variety of housing types, including small-lot single-family housing, and various types of multifamily housing (for example, duplexes, townhouses, and apartments). The maximum allowable density ranges from six to ten dwellings per acre, with the specific allowable density for each parcel shown on the zoning map by a numerical suffix to the RM map symbol (see Section 13.24.050 ). The RM zoning district is consistent with and implements the residential - medium-high density land use designation of the general plan.
F. RH (High Density Residential) Zoning District. The RH zoning district is applied to areas appropriate for various types of multifamily housing, including duplexes, townhouses and apartments. The maximum allowable density ranges from ten to fifteen units per acre. The RH zoning district is consistent with and implements the residential - high density land use designation of the general plan.
G. RH-20 (High Density Residential - 20 Units Per Acre Minimum) Zoning District. The purpose of this zoning district is to provide adequate sites for multifamily housing at a minimum

of twenty units per acre and up to twenty-five units per acre "by right" (without conditional use permit or other discretionary action), including sites that could accommodate very low and lowincome units. Alternative standards to the RH development standards in Section 13.24.040 Table 2-4 and the RH Specific Use Regulations in Section 13.42.250 may be considered in order to achieve the goal of meeting affordable housing requirements.

(Ord. 205 § 1 (Exh. A), 2003; Ord. 255 § 1, 2014; Ord. 299, 11/12/2024)

§ 13.24.025. Residential incentives. ¶

The town shall allow residential incentives in compliance with state law, including, but not limited to:

A. Density bonuses for construction of units for low and very low-income households, qualifying residents (senior citizens) and persons and families of moderate income. See Section 13.32.020 — Eligibility for bonus and incentives.
B. Allowing cluster development. See Section 13.24.080 — Clustered residential development.
C. Reduced parking requirements. See Section 13.36.080 — Reduction of parking requirements and Section 11.16.070 Incentives and alternatives.
(Ord. 299, 11/12/2024)

§ 13.24.030. Residential district land uses and permit requirements. ¶

Table 2-2 identifies the uses of land allowed by this title in each residential zoning district, and the land use permit required to establish each use, in compliance with Section 13.22.030 .

NOTE: Where the last column in the table ("Specific Use Regulations") includes a section number, the regulations in the referenced section apply to the use. Provisions in other sections of this title may also apply.

(Ord. 205 § 1 (Exh. A), 2003; Ord. 299, 11/12/2024)

§ 13.24.040. Residential district general development standards. ¶

Subdivisions, new land uses and structures, and alterations to existing land uses and structures, shall be designed, constructed, and established in compliance with the requirements in Tables 2-3, and 2-4 in addition to the applicable standards (e.g., landscaping, parking and loading, etc.) in Division 3 of this title.

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.

Notes:

(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 Section 13.24.020(G) for RH-20 zone district.
(6) Multifamily housing developments for special needs groups are permitted an increased density of 20 dwelling units per acre.
(7) 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.

§ 13.24.050. RS & RM district density—Parcel size—Site coverage.

The maximum allowable density, minimum parcel size requirements for new subdivisions, and maximum site coverage requirements for parcels in the RS and RM zoning districts are established by Table 2-5. The application of these requirements to property within the town is shown on the zoning map (Chapter 13.20 ) by means of a numerical suffix being appended to the RS and RM zoning map symbols. Each applicable suffix is shown in the "Zoning District and Suffix" column of Table 2-5.

§ 13.24.060. RE district standards. ¶

Subdivisions, other development and new land uses within the RE zoning district located immediately northwest of the intersection of Rocklin and Barton Roads shall comply with the following standards, as applicable.

A. Minimum Lot Area. Proposed subdivisions shall be designed to provide parcels with a minimum of 4.6 acres along the Barton and Rocklin Road frontages, and a minimum of 2.3 acres when located away from Barton and Rocklin Roads.
B. Vegetation Preservation. Where there are existing native trees or slopes of more than ten percent, proposed building sites should be set back from Rocklin Road and Barton Road to retain native vegetation and terrain features, and preserve the present appearance as a rural road corridor.
C. Access. Access to new parcels shall be provided by new roads from Barton Road and Rocklin Road, with no individual driveway access to Rocklin Road. There shall be a limit to no more than one curb cut per parcel for direct access to Rocklin Road.
(Ord. 205 § 1 (Exh. A), 2003; Ord. 299, 11/12/2024)

§ 13.24.070. RS district standards. ¶

Development within the RS-10a zoning district on the site immediately south of the H. Clark Powers School on the west side of Humphrey Road shall comply with the following standards, consistent with Specific Area Policy 6, Section G of the Land Use and Community Development Element of the general plan.

A. The allowable density of two to six dwelling units per acre shall be distributed on the site with lower density on the edges of the parcel.
B. An application proposing subdivision of the property shall demonstrate special attention to potential flooding and drainage issues, and any proposed project shall be designed to create no greater volume of storm water runoff to downstream properties after development.

§ 13.24.080. Clustered residential development. ¶

A. Purpose and Intent. This section provides for the subdivision of properties within large-lot residential zoning districts, whereby individual homesite parcels are clustered within carefully selected areas of the original parcel to be subdivided.
1. As provided by the general plan, clustered residential development is intended for use under very limited circumstances, where specific site characteristics of access, scenic rural character, slopes, soil stability, environmental resources, infrastructure or other similar factors are sufficiently sensitive or constraining to warrant a different approach to subdivision than provided by the normal minimum parcel size requirements of the applicable zoning district.
2. In these cases, the town may allow development to be clustered in restricted areas of the site, on parcels smaller than normally allowed by the applicable zoning district, in return for permanently maintaining the more sensitive areas in an undeveloped state, and provided that the total residential density does not exceed that allowed by the applicable zoning district and the general plan.
3. It is the intent of the town that the approval and construction of a clustered residential development shall not be used as justification for a subsequent amendment to the general plan designation or zoning of the overall site or any individual parcel.
B. Where Allowed. Clustered residential development in compliance with this section shall be allowed only within the RA, RE, RR, and RS zoning districts.
C. Permit Requirement. Clustered residential development shall require use permit approval in addition to tentative and final map approval. Use permit approval shall include conditions specifying a phasing schedule for the recordation of a final map and, where applicable, the installation of required improvements, and a date for the expiration of town approvals in the event the subdivision and development is not completed within the specified schedule.
D. Maximum Density and Number of Parcels. The maximum number of individual building sites allowed in a clustered residential development shall not exceed the number of parcels allowed through application of the minimum lot area requirements established for the applicable zoning district by this chapter. Net lot area (see definition of "lot area") shall be used to determine the number of allowable parcels.
E. Parcel Area and Open Area Requirements. The minimum area required of a parcel to be subdivided to qualify for clustered residential development, and the minimum area of parcels created through cluster division shall comply with the requirements of Table 2-6.

TABLE 2-6	- MINIMUM PARCEL SIZE FOR CLUSTERED RESIDENTIAL	- MINIMUM PARCEL SIZE FOR CLUSTERED RESIDENTIAL	- MINIMUM PARCEL SIZE FOR CLUSTERED RESIDENTIAL
Zoning District	Minimum Area of Parcel to be Subdivided (1)	Minimum Area of Building Site Parcels (1) (2)	Minimum Area of Open Space Parcel (3)
RA	40 acres	2.3 acres	40%
RE	20 acres	1 acre	60%
RR	10 acres	10,000 sf	50%
RS	10 acres	10,000 sf	50%

Notes:

(1) Net lot area.
(2) A minimum lot area of less than 2.3 acres may be approved within the RA zoning district only when community water or sewer service is provided.
(3) The minimum area is expressed as a percentage of the gross area of the parcel to be subdivided.
F. Design Standards.
1. Open Space Parcel Required. A clustered residential development shall include at least one open space parcel, which shall not be developed with structures other than agricultural accessory buildings. The open space parcel may be used for any of the following, if specifically authorized by the use permit approval for the clustered development: crop production, orchards, or grazing; habitat or other nature preserves, water storage or recharge; scenic areas; or other similar open space use.
2. Guarantee of Open Space. The required open space parcel shall be maintained as open space in perpetuity. The permanent open space shall be guaranteed by an open space easement, or dedication of fee or partial fee title to a public or quasi-public agency (e.g., the town, a land trust, etc.).
3. Site Design.
  - a. Site disturbance shall be minimized by clustering, locating roads along contours, and building site selection.
  - b. Access to off-site roads shall be limited, with clustered parcels having access from interior roads wherever feasible.
  - c. Development shall be designed to be consistent with the character of the immediate surrounding areas as determined by the applicable zoning district.
  - d. Building site parcels shall be clustered and located within the parcel to be subdivided to minimize the visibility of proposed residential units and other structures from public roads and abutting parcels.
  - e. The clustered parcels and the overall development shall at no time be gated to limit public access to the roads within the site.
G. Required Findings. The approval of a use permit to allow a clustered residential development shall require that the review authority first make all of the following findings, in addition to those otherwise required for use permit approval by Section 13.62.050 .
1. The proposed project will be more compatible with existing and future land uses adjacent to the site and in the vicinity than a conventional subdivision of the site;
2. The proposed project will more effectively and appropriately mitigate environmental impacts, including the avoidance and preservation of environmentally sensitive areas on the site than a conventional subdivision of the site; and

The proposed project will more effectively and appropriately maintain the rural character of Loomis in terms of the visibility of proposed structures and site improvements from public roads and adjacent parcels than a conventional subdivision of the site.
