§ 23.07.172. Wetlands.
Development proposed within or adjacent to (within 100 feet of the upland extent of) a wetland area shown on the Environmentally Sensitive Habitat Maps shall satisfy the requirements of this section to enable issuance of a land use or construction permit. These provisions are intended to maintain the natural ecological functioning and productivity of wetlands and estuaries and where feasible, to support restoration of degraded wetlands.
a.
Location of development: Development shall be located as far away from the wetland as feasible, provided that other habitat values on the site are not thereby more adversely affected.
b.
Principle Permitted Uses in wetlands: Hunting, fishing, wildlife management, education and research projects.
c.
Department of Fish and Game review. The State Department of Fish and Game shall review all applications for development in or adjacent to coastal wetlands and recommend appropriate mitigation measures where needed which should be incorporated in the project design.
d.
Wetland setbacks: New development shall be located a minimum of 100 feet from the upland extent of all wetlands, except as provided by subsection d(2). If the biological report required by Section 23.07.170 (Application Content) determines that such setback will provide an insufficient buffer from the wetland area, and the applicable approval body cannot make the finding required by Section 23.07.170b, then a greater setback may be required.
(1)
Permitted uses within wetland setbacks: Within the required setback buffer, permitted uses are limited to passive recreation, educational, existing non-structural agricultural development in accordance with best management practices, utility lines, pipelines, drainage and flood control of facilities, bridges and road approaches to bridges to cross a stream and roads when it can be demonstrated that:
(i)
Alternative routes are infeasible or more environmentally damaging.
(ii)
Adverse environmental effects are mitigated to the maximum extent feasible.
(2)
Wetland setback adjustment: The minimum wetland setback may be adjusted through Minor Use Permit approval (but in no case shall be less than 25 feet), provided that the following findings can be made:
(i)
The site would be physically unusable for the principal permitted use unless the setback is reduced.
(ii)
The reduction is the minimum that would enable a principal permitted use to be established on the site after all practical design modifications have been considered.
(iii)
That the adjustment would not allow the proposed development to locate closer to the wetland than allowed by using the stringline setback method pursuant to Section 23.04.118a of this title.
(3)
Requirements for wetland setback adjustment: Setbacks established that are less than 100 feet consistent with this section shall include mitigation measures to ensure wetland protection. Where applicable, they shall include landscaping, screening with native vegetation and drainage controls. The adjustment shall not be approved until the approval body considers the following:
(i)
Site soil types and their susceptibility to erosion.
(ii)
A review of the topographic features of the site to determine if the project design and site location has taken full advantage of natural terrain features to minimize impacts on the wetland.
(iii)
The biologists report required by Section 23.07.170 shall evaluate the setback reduction request and identify the types and amount of vegetation on the site and its value as wildlife habitat in maintaining the functional capacity of the wetland.
(iv)
Type and intensity of proposed development.
(v)
Lot size and configuration and location of existing development.
e.
Site development standards:
(1)
Diking, dredging, or filling of wetlands: Diking, dredging, or filling activities in wetland areas under county jurisdiction shall be allowed only to the extent that they are consistent with Environmentally Sensitive Habitats Policy 13 of the San Luis Obispo County Coastal Plan Policies, and shall not be conducted without the property owner first securing approval of all permits required by this title. Mineral extraction is not an allowed use in a wetland.
[Amended April 2006, Ord. 3082]
(2)
Vehicle traffic: Vehicle traffic from public roads shall be prevented from entering wetlands by vehicular barriers, except where a coastal accessway is constructed and designated parking and travel lanes are provided consistent with this title. The type of barrier and its proposed location shall be identified in the materials accompanying an application for a land use permit and must be approved by the Planning Director before permit issuance to insure that it will not restrict local and state agencies or the property owner from completing the actions necessary to accomplish a permitted use within the wetland.
(3)
Open space easement required: A land use or construction permit for a structure larger than 1000 square feet in floor area shall not be approved on a parcel of one acre or larger that contains a wetland, unless the property owner first grants the county or an approved land trust an open space easement or fee title dedication of all portions of the site not proposed for development, as well as the entire wetland.
[Amended 2006, Ord. 3082]
