Title: 21 - Coastal Zoning

Chapter: 11A - RCA2 Designated Resource Conservation Area District

Section: 60 - Supplemental application data

Where development is proposed wholly or partially within a resource conservation area and/or any buffer which may be required for it, a supplemental information report may be required as part of the permit application. If such is required, it should investigate physical and biological features existing in the habitat area and evaluate the impact of the development on the existing ecosystem. The report should be based on on-site investigation, in addition to a review of the existing information on the area, and should be sufficiently detailed to enable the planning commission to determine potential immediate and long-range impacts of the proposed project.

       The report should describe and analyze the following:

     A.  That information required in Section 21.11.060(A) which has not previously been reviewed and/or requires up-dating

     B.  Present extent of the habitat, and if available, maps, photographs or drawings showing historical extent of the habitat area

     C.  Previous and existing ecological conditions:

        1.  The history, ecology and habitat requirements of the relevant resources, such as plants, fish and wildlife, in sufficient detail to permit a review of functional relationships (the maps described above may supply part of this information),

        2.  Restoration potentials

     D.  Present and potential adverse physical and biological impacts on the ecosystem

     E.  Alternatives to the proposed development, including different projects and off-site alternatives

     F.  Mitigation measures, including restoration measures and proposed buffer areas

     G.  If the project includes dredging, explain the following:

        1.  The purpose of the dredging,

        2.  The existing and proposed depths,

        3.  The volume (cubic yards) and area (acres or square feet) to be dredged,

        4.  Location of dredging (e.g., estuaries, open coastal waters or streams),

        5.  The location of proposed spoil disposal,

        6.  The average grain size distribution of spoils,

        7.The occurrence of any pollutants in the dredge spoils

     H.  If the project includes filling, identify the type of fill material to be used, including pilings or other structures, and specify the proposed location for the placement of the fill. The quantity to be used and the surface area to be covered and any proposed use of the fill area

     I.  If the project includes diking, identify on a map the location, size (length, top and base width), depth and elevation of the proposed dike(s), as well as the location, size and invert elevation of any existing or proposed culverts or tide gates

     J.  If the project is adjacent to a wetland or wetland buffer and may cause mud waves, a report shall be prepared by a qualified geotechnical engineer which explains ways to prevent or mitigate the problem

     K.  Benchmark and survey data used to locate the project, the lines or highest tidal action, mean high tide, or other reference points applicable to the particular project.
