§ 30.53.120. Application Submittals.
A.
Applications for development of property within the Lagoon Overlay Zone shall include topographic and vegetative maps, as necessary, to delineate the boundaries of all wetland areas located on-site or off-site in proximity to the development proposal. Maps required by this Section shall be of a scale not less than one inch equals 100 feet and shall delineate the topography of the site in two-foot contour intervals. The determination of the boundary of wetland areas shall be included as an overlay to the required topographic map and shall be prepared by a qualified professional(s) in the fields of biology and hydrology. The Director of Planning and Community Development shall have the discretion to contact representatives of the California Department of Fish and Game and the United States Fish and Wildlife Service to confirm the wetland boundary information and determination provided by an applicant(s).
B.
Applications involving grading on property, which includes, or lies in proximity to wetland areas as defined in this Chapter shall include a grading plan prepared by a registered civil engineer. The grading plan shall be designed to ensure that there will be no increase in the peak runoff rate from the fully developed site over the greatest discharge that would occur from the existing undeveloped site as a result of the intensity of rainfall expected during the six-hour, ten-year design storm. The grading and erosion control plan shall include:
1.
Plans for all runoff and erosion control measures to be installed including: catchment basins, detention basins, and siltation traps along with energy dissipating measures at the terminus of storm drains, and other similar measures of equal or greater effectiveness.
2.
A description of the erosion control procedures to be utilized during all phases of project development.
3.
Plans prepared by a licensed landscape architect or other qualified professional for the installation of temporary and permanent landscaping for soil retention.
