44-2.40 Commercial

Zoning Classifications.

(Ord. No. 765 § 2 (Exh. A) (part))

44-2.40.10 Purpose of the Commercial Zones.

A. Neighborhood Commercial (C-1). The purpose of the C-1 zone is to allow for retail and service uses that meet the daily needs of nearby residents and workers, and to provide convenient residential access to sales and service facilities without detracting from the residential desirability of such areas.

B. Community Commercial (C-2). The C-2 zone is intended to apply to areas where more complete commercial facilities are necessary for community convenience. The purpose of the C-2 zone is to allow for a full range of retail, service, and office uses to serve residents, workers, and visitors.

C. Highway Service Commercial (C-H). The C-H zone is intended to provide necessary services and conveniences for the traveling public along main roads and highway frontages at proper intervals and locations in developments designed for safety, convenience, and suitable appearance.

D. Commercial Resort (C-R). The C-R zone is intended to provide opportunities for a mix of commercial uses oriented towards tourists and other visitors to the County, including but not limited to, agriculturally based tourism, sports fishing, hunting, marinas, lodging, and other related uses.

E. Mixed Use (MU). The MU zone is intended for areas appropriate for the planned integration of a combination of retail, office, residential, hotel, recreation, public facilities and/or other compatible use. The MU zone encourages placing housing, jobs, services, and recreational land uses close together within a project site, or on different stories of the same building. This zoning classification is established primarily in the community centers, downtown areas, and in-fill areas to encourage economic investment and revitalization of these core areas through promoting community-serving retail, office, and residential opportunities in a dense, compact form with opportunities for people to access the project and other destinations through bicycle, pedestrian, and mass transit modes. Projects in the MU zone should focus on compatibility between land uses, and the development potential of a given area compared to the existing and proposed mix of land uses and their development impacts. This zone is intended to protect and enhance the character of the area and to provide flexibility in design and use for contiguous parcels having multiple owners. (Ord. No. 765 § 2 (Exh. A) (part))

44-2.40.20 Development Standards in the Commercial Zones.

(a) Allowed uses and associated structures shall comply with the following development standards, in addition to any other applicable requirements of this title, unless a variance is obtained in compliance with section 44-1.90.050.
