Martinez City Zoning Code
CHAPTER 22
23 DOWNTOWN SHORELINE DISTRICTS DS
§ 22.23.010 Purpose.
The intent of the Downtown Shoreline District is to provide for a variety of residential uses in an environment that is transitioning from industrial to residential uses. This district serves as a transition area between the urbanized portion of the downtown and the open space of the Martinez Regional Shoreline to the north. The standards and guidelines for this district are intended to protect and enhance the environmentally sensitive areas of the Shoreline, to respect and complement the existing primarily single-family neighborhood immediately to the south, and to contribute to the economic revitalization of downtown, by permitting a sufficient intensity of development to provide an economic incentive for industrial uses to relocate.

§ 22.23.050 Development standards for the downtown shoreline district.
A.
General. All new multiple residential development in this district shall be processed concurrently with a subdivision map, so that individual units can be offered for sale, and shall meet the requirements for new condominium units as contained in Chapter 21.54.
B.
Maximum Height. The maximum building height in the Downtown Shoreline District shall be 40 feet, or 3 stories, for developments approved for a density of 35 units per acre (see below); otherwise the height limit shall be 30 feet, or 2 stories. In some areas, such as transition areas near existing single-family residential areas, a 2-story maximum height may be determined to be appropriate by the Planning Commission. The Planning Commission may approve taller buildings by use permit.
C.
Density. The minimum site area per residential unit shall be 2,100 square feet (20 units per acre). The Planning Commission may approve a reduced site area per unit, down to a minimum of 1,250 square feet per unit (35 units per acre), by use permit. In order to approve a density above the lower end of the density range, the Planning Commission would need to find that in addition to meeting the above minimum requirements, the proposal is superior in terms of two or more of the following criteria:
1.
Assembling all or most of the contiguous parcels into one project, and designing the project as a new neighborhood;
2.
Design and appearance;
3.
Minimizing impacts on adjacent public lands;
4.
Providing on-site amenities for the future residents;
5.
Preserving or creating view corridors from public streets such as Talbart, Buckley, Marina Vista, Carquinez Scenic Drive, Castro and Berrellesa;
6.
Utilizing green building practices to the maximum extent possible;
7.
Providing a variety of housing types, including detached single-family residential, where feasible, as a transition in areas near existing single-family neighborhoods;
8.
Providing a new public street system that improves access to the Regional Shoreline and Alhambra Creek, potentially by extending Alhambra Avenue along the creek, and vacating Berrellesa. In order to approve a density at or near the upper end of the density range, the Planning Commission would need to find that the proposal is superior in terms of all or almost all the above criteria.
D.
Other Development Standards. Setbacks, lot standards, coverage, etc., shall be as provided in the Downtown Overlay District, Sections 22.13.040 through 22.13.090, inclusive.
