16.10 Commercial Districts

This chapter provides regulations applicable to development and new land uses in the commercial zoning districts established by 16.06.010 (Zoning Districts Established). The purposes of the individual commercial zoning districts and the manner in which they are applied are as follows:

A. NC (Neighborhood Commercial) District. The NC zoning district is applied to areas appropriate for convenience shopping, including individual retail and service uses and small destination centers on sites generally three to ten acres in size. Appropriate buffering between adjacent residential designations is required. The NC zoning district is consistent with the commercial land use designation of the general plan;

B. CC (Community Commercial) District. The CC zoning district is applied to areas appropriate to serve the daily shopping needs of the community, including destination centers, supermarkets, and smaller, single-lot, commercial activities. Financial, office and restaurant activities are also allowed. Appropriate buffering between adjacent residential designations is required. Community centers are generally ten (10) to thirty (30) acres in size. The CC zoning district is consistent with the commercial land use designation of the general plan;

C. RC (Regional Commercial) District. The RC zoning district is applied to areas appropriate for major regional centers containing several major anchor tenants, including, but not limited to, financial, hotel, motel, restaurant, smaller retail, theater and accessory uses, with landscaping, parking access, and signs designed and provided in common. Regional centers are generally thirty (30) acres or larger in size. The RC zoning district is consistent with the commercial land use designation of the general plan.

The following standards and design features are provided to ensure a level of quality that must be compiled with or satisfied in all commercial developments. Standards are mandatory requirements for all commercial developments. Design features are provided to allow flexibility by providing options for implementing specific standards. In order to meet a certain standard, one or a combination of design features shall be incorporated in the project’s design. In some instances, there will be no design feature(s) identified for a particular standard.

A. Site Planning.

1. Site Character.

a. Standard. Natural amenities (e.g., views, mature trees, creeks, riparian corridors, and topographic features) unique to the site shall be preserved and incorporated into the project's design whenever possible.

• tubing shall not be an acceptable feature for building trim or accent areas except for movie theaters.

• c. Standard: The transition between base and accent colors shall relate to changes in building materials or the

• change of building surface planes. Colors should not meet or change without some physical change or definition to the

surface plane.

7. Additions to Existing Structures.

a. Standard: The design of an addition to an existing structure shall follow the general scale, proportion, massing, and detailing of the original structure. The addition shall be harmonious with the original structure, not a stark contrast.

b. Standard: Additions shall be an interpretation of the existing building wherein the main characteristics of the existing structure are incorporated into the design of the addition by use of at least two of the following design features:

Parameters:

• 1. Repeat window and door spacing;
• 2. Use harmonizing colors and materials; and
• 3. Include similar, yet distinct, architectural details (e.g., window/door trim, lighting fixtures, tile/brick
