Landscaping and Open Space Requirements for the Wetlands and Resource Conservation (WRC) District
The Wetlands and Resource Conservation (WRC) District is designated to ensure the protection of wildlife, hydrological, and biological resources in marsh and wetland areas. Landscaping and open space in the WRC District are guided by the specific goals of habitat preservation, with development standards being supplemental to those found in the wider Concord Development Code.
Landscaping and Open Space in the WRC District
The Wetlands and Resource Conservation (WRC) District is established to protect bay marshes and wetlands within the tidal area of Concord [Section 18.60.010]. Because the WRC District is intended to ensure the protection of wildlife, hydrological, and biological resources, development is carefully managed to preserve these values in perpetuity [Section 18.305.010].
Landscape and Open Space Standards
Development in the Wetlands and Resource Conservation (WRC) District must comply with the general landscape requirements for Community Land Districts, where the minimum area of the site to be landscaped is determined at the discretion of the review authority [Section 18.165.050].
When drainage improvements are necessary in the Wetlands and Resource Conservation (WRC) District, they must be placed in the least visible locations and designed using natural materials, such as river rock and earth-tone concrete, and landscaped with native plant materials [Section 18.305.040]. Additionally, the use of permeable surfaces, such as wood plank decks or sand-joined bricks, is encouraged within the Wetlands and Resource Conservation (WRC) District to minimize off-site water flows and facilitate absorption [Section 18.305.040].
Protection of Natural Features
Riparian habitat and wetland preservation are prioritized within the Wetlands and Resource Conservation (WRC) District:
- Vegetation Removal: The removal of native vegetation is prohibited within structure setback areas, except when authorized for flood control purposes via proper permits from the California State Department of Fish and Game or other relevant agencies [Section 18.305.040].
- Creek Bank Stabilization: Creek rehabilitation is the preferred method for stabilizing banks in the Wetlands and Resource Conservation (WRC) District to maintain natural character. Concrete channels or mechanical stabilization measures are only allowed if no other alternatives exist [Section 18.305.040].
- Access: The provision of multi-purpose creekside trails and public open space is encouraged in the Wetlands and Resource Conservation (WRC) District. Paths and other recreational amenities may be provided outside of the identified riparian habitat area [Section 18.305.040].
