28.32.10 Residential-Traditional Community Districts

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

Exceptions & meaning →

28.32.11 Purpose of Residential-Traditional Community 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:

Birds Landing R-TC-1AC
Collinsville Township R-TC-4
Cordelia area R-TC-15
Elmira area R-TC-1AC and R-TC-20
Fairfield Unincorporated area R-TC-1AC, R-TC-20, R-TC-10 and R-TC-D
Green Valley area R-TC-1AC, R-TC-20, and R-TC-15
Rockville Corners R-TC-1AC
Snug Harbor area R-TC-10
Vallejo Unincorporated area R-TC-20, R-TC-10, R-TC-6, R-TC-5, R-TC-D & R-TC-MF
Willotta Oaks area R-TC-15, R-TC-10

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:

Vallejo Unincorporated Area R-TC-MU
Birds Landing Area R-TC-MU
Cordelia area R-TC-MU
Elmira area R-TC-MU
