approved permits for construction of structures, sewage treatment systems, and driveways shall <br />adhere to the grading and filling standards of this article. <br />(b) Grading, filling or excavating of more than 50 cubic yards is prohibited within 75 feet of the ordinary <br />high water level of the public waters enumerated in section 78-1217. <br />(c) Public and private roads, driveways, parking areas, and public or private watercraft access ramps <br />shall not be constructed within 75 feet of the ordinary high water level of the public waters <br />enumerated in section 78-1217. If no alternatives exist, such improvements shall be subject to the <br />standard zoning variance review procedure, and such review shall take into account the following <br />considerations: <br />(1) Such improvements shall be designed to take advantage of natural vegetation and topography <br />to achieve maximum screening from view from public waters. <br />(2) All roads and parking areas shall be designed and constructed to minimize and control erosion <br />to public waters consistent with the requirements of all agencies with jurisdiction. <br />(d) Except for those projects requiring permits for construction of structures, sewage treatment systems <br />and driveways, a land alteration permit will be required as follows: <br />(1) For movement of up to 50 cubic yards of material within 75 feet of public waters as per item (b) <br />above, a staff-issued land alteration permit shall be required. <br />(2) For movement of 51 through 500 cubic yards of material anywhere within the Shoreland <br />Overlay District, except for within 75 feet of public waters, a staff-issued land alteration permit <br />shall be required. <br />(3) For movement of more than 500 cubic yards of material within the Shoreland Overlay District, <br />conditional use permit approval by the city council is required in addition to the required land <br />alteration permit. <br />(e) The following considerations and conditions must be adhered to during the issuance of construction <br />permits, grading and filling permits, conditional use permits, variances and subdivision approvals: <br />(1) Grading or filling in any type 1, 2, 3, 4, 5, 6, 7 or 8 wetland must be evaluated to determine how <br />extensively the proposed activity would affect the following functional qualities of the wetland: <br />a. Sediment and pollutant trapping and retention; <br />b. Storage of surface runoff to prevent or reduce flood damage; <br />c. Fish and wildlife habitat; <br />d. Recreational use; <br />e. Shoreline or bank stabilization; and <br />f. Noteworthiness, including special qualities, such as historic significance, critical habitat for <br />endangered plants and animals, or others. <br />This evaluation must also include a determination of whether the wetland alteration being <br />proposed requires permits, reviews or approvals by other sections of city ordinances or by other <br />local, state or federal agencies including but not limited to watershed districts, state department <br />of natural resources, or the United States Army Corps of Engineers. <br />(2) Alterations must be designed and conducted in a manner that ensures only the smallest <br />amount of bare ground is exposed for the shortest time possible. <br />(3) Mulches or similar materials must be used, where necessary, for temporary bare soil coverage, <br />and a permanent vegetation cover must be established as soon as possible. <br />(4) Methods to minimize soil erosion and to trap sediments before they reach any surface water <br />feature must be used.
