Chapter 28

Zoning Regulations

Agriculture is the major industry in the County generating the majority of the tax revenue in the unincorporated County. Also, agriculture is the largest single zone district classification on the County zoning map. Therefore, the Board of Supervisors has determined that the promotion and preservation of agriculture is of vital interest to the County. The standards stated in this section preserve agriculture a number of ways, including allowing agricultural-related support uses, excluding incompatible uses, and protecting the viability of the family farm. These regulations support the family farm by allowing a secondary dwelling for family members that acts as a form of affordable housing and, for farms with larger acreage, permits a reasonable number of farm labor housing on or near the farming activity.

• A. Allowed Uses and Permit Requirements. Table 28.21A identifies the land uses allowed by right in each agricultural district and the Land Use Permit required to establish each use. In addition to the Land Use Permit required by Table 28.21A, special requirements may apply to certain uses.

• B. Architectural Review. Architectural Approval may be required for certain uses in compliance with Section 28.102 (Architectural Approval).

• C. Land Use Regulations. Where the last column in the Table 28.21A (Land Use Regulations) includes a section number, e.g., 28.21.10, the zoning regulations in the referenced section apply to the use. Where the last column includes a chapter number, e.g., Chapter 13.6, the regulations in the referenced chapter of the Solano County Code apply to the use. Provisions in other sections of this chapter or in other chapters of the Solano County Code may also apply.

• D. Site Development and Other Standards. All uses shall comply with the provisions of Article IV of this chapter, relating to site development and other standards and beginning with Section 28.90, which includes standards for parking, signs and other project elements.

This section includes regulations for the A-SM-80 and A-SM-160 zoning districts.

This Section lists the uses of land that may be allowed within the Suisun Marsh Agricultural zoning districts, established by Section 28.13 (Districts Designated and Established). It also determines the type of land use approval required for each type of use and provides general standards for site development.

Agriculture is the major industry in Solano County, generating the majority of the tax revenue in the unincorporated County. In addition, certain agricultural lands serve an important function in buffering contiguous environmentally sensitive lands of the Suisun Marsh from the effects of urbanization. Therefore, the Board of Supervisors has determined that it is in the interest of the County to prevent further encroachment upon such agricultural lands by incompatible uses of property.

The purpose and intent of the A-SM districts is to preserve lands best suited for permanent agricultural use while limiting certain intensive agricultural practices which may conflict with adjoining sensitive lands. A primary intent of the A-SM districts is to assure the retention of upland and lowland grasslands adjacent to the Suisun Marsh in uses compatible with its protection.

• A. Allowed Uses and Permit Requirements. Table 28.22A identifies the land uses allowed by right in each Suisun Marsh agricultural district and the land use permit required to establish each use. In addition to the land use permit required by Table 28.22A, special requirements may apply to certain uses.

• B. Marsh Development Permit Requirements. Any development within the Suisun Marsh, as defined by Section 29114 of the Public Resources Code, shall be subject to obtaining a marsh development permit pursuant to the Suisun Marsh Preservation Act of 1977, and as provided for in Section 28.104. When a land use subject to a marsh development permit is proposed in both the primary management area and secondary management area, as defined in the Suisun Marsh Preservation Act of 1977, the land use shall be subject to a use permit covering the whole of the project.

The overall existing development area may not be expanded under these provisions. Development within the existing development area should minimize additional impervious surfaces. An adequate buffer should be established or maintained between the development areas and any water, wetlands, or other marsh habitat to protect the habitat from adverse environmental impacts. An erosion, sediment, and runoff control plan shall be prepared in accordance with Section 31-26(b) regulating grading, drainage, land leveling and erosion control. When the nonconforming use is located in both the primary and secondary management areas, as defined by the Suisun Marsh Preservation Act of 1977, nonsubstantial changes, alterations, and additions to the nonconforming use shall be subject to a use permit covering the whole of the project.

Zoning Regulations

This Section lists the uses of land allowed within the Agriculture-Suisun Valley and the Agriculture Tourist Center zoning districts (ATC and ATC-NC) zoning districts as established by Section 28.13 (Districts Designated and Established). It also determines the type of land use approval required for each use, and provides general standards for site development.

The majority of land within Suisun Valley is in agricultural use, producing grapes for wine, small grains, or other fruit crops. This farmland is essential to the Valley’s agricultural economy and quality of life. The standards in this section maximize the viability of the family farm by allowing uses that support agriculture and excluding incompatible uses.

Development of agricultural tourism is critical to the future viability of agriculture in Solano County. The standards in this section allow a variety of uses that will help foster small touristoriented centers within the Valley, help attract tourists, and provide additional opportunities to market local products

Retail Stores and Services:

Retail stores and services, businesses and professional offices providing convenience goods and services to serve a rural community and tourists to an agricultural area, conducted either entirely within a building or buildings on a single ownership or, where permitted, within a building and outdoors.

This Section includes regulations for the RR-2.5, RR-5 and RR-10 zoning districts.

This Section lists the uses of land that may be allowed within rural residential areas of the County represented by the Rural Residential (R-R) zoning districts. It also determines the type of land use approval required for each use within each district, and provides general standards for site development.

Rural Residential zoning is applied to areas appropriate for rural, low density, single-family homes, where agriculture is not the sole land use and commercial agricultural production capability is low, where self-sufficiency and privacy are desirable and only minimal essential public services and facilities are available. Homesites are to be self-sufficient, with individual wells and individual septic systems. Water may be supplied by a public water system, operated by a public agency, in areas where water from individual wells may be of marginal quantity or quality. Rural Residential is to be applied in a manner that preserves rural character and scenic qualities and protects sensitive resources including agricultural lands, creeks, native trees, open spaces and views. Rural Residential zoning shall not be applied to agricultural lands, or to areas with a high risk of wild

Zoning Regulations

This Section includes regulations for the following zoning districts

• A. Residential - Traditional Community (R-TC) Districts

• B. Residential - Traditional Community Mixed Use (R-TC-MU) Districts

This Section lists the uses of land that may be allowed within the traditional community residential areas of the County represented by the Residential-Traditional Community (R-TC) zoning districts. It also determines the type of land use approval required for each use within each district, and provides general standards for site development.

Residential-Traditional Community districts recognize current residential and mixed-use communities located outside agricultural or municipal service areas where previous development has occurred at higher densities or intensities than currently allowed under County policy. It is the intent to preserve and enhance the character and quality of these communities and promote future infill residential and mixed use development but not to expand the area of these communities.

The R-TC Districts replace the following previous districts:

R-TC-1AC replaces RE-1;

R-TC-20 replaces RE-1/2 R-TC-15 replaces RE-1/3 R-TC-10 replaces RE-1/4 R-TC-6 replaces R-S-6 R-TC-5 replaces R-S-5

R-TC-D-4 replaces R-D (Starr Subdivision)

R-TC-D-6 replaces R-D (Homeacres)

R-TC-MF replaces R-M

The purpose of the different residential - traditional community zoning districts and the manner in which they are applied are as follows:

A. Residential-Traditional Community (R-TC) Districts

The R-TC zoning districts are intended for areas that have previously been subdivided for single family residential development and provide the community services appurtenant thereto. The

regulations for these districts are designed to stabilize and protect the residential characteristics of the districts, to promote and encourage a suitable environment for family life. Nine R-TC zoning districts are denoted with a suffix to indicate the minimum parcel size (e.g. R-TC-4 requires a minimum parcel size of 4,000 square feet), minimum building setbacks, and other requirements. The R-TC zoning districts are consistent with and implement the Traditional Community - Residential land use designation of the General Plan as follows:

B. Residential-Traditional Community Mixed Use (R-TC-MU) Districts

The Residential -Traditional Community Mixed Use (R-TC-MU) zoning district is intended for certain medium-density residential and retail commercial and business areas that are appropriate for residential and commercial uses, and that can be served by community services. The regulations for this district are designed to stabilize and protect the essential residential characteristics of the district, to promote and encourage a suitable environment for family life and to provide for the integration of retail shops and businesses into the neighborhood. The R-TC-MU zoning district is consistent with and implements the Traditional Community-Mixed Use land use designation of the General Plan as follows:

A. Allowed Uses and Permit Requirements

Tables 28-32A and 28-32A1 identifies the land uses allowed by this Zoning Ordinance in each residential-traditional community district and the land use permit required to establish each use.
