d. Type of proposed surfacing; e. Method of perimetar erosion control; f. Proposed use of fili: d area. The perimeter of all lan ifil!; must be provided with some means to control erosion, such as vegeta �ion, retaining walls, or other mechanisms. The Applicant provided ��roposed grading infortnation on the site plan. The proposal would include the stripping and stockpiling of on-site topsoil for use in landscaping and ��ard areas. On-site fill would be obtained from cut areas along the westem ��ortion oF the site. This matenal consists of glacial till. Approximately 15,G00 cubic yards of matenal will be moved on-site, with a balance between on•site cut and on-site fill proposed. Compaction under build ngs must occur per Unifortn Building Code requirements. Compection for all public utilities must occur per Public Works Design and Construction Standards and Specifications (see Condition 2 on page ;. of the MDNS). Erosion control must occur per the Erosion and Sedimentation Control Plan appmved by the Public Works Depanment (see Condition 12 on page 3 of the �vIDNS). Conclusion: The proposed landfilling should not adversely impact the shoreline areas, based upon compliance with the conditions listed on the MDNS and wilh Unifortn Building Code requirements. Shoreline Stabilizatfon and Flood Protection Findin : The Casper Creek property is not designated as being in a flood fnnge district. However, the Ciry of Everett has estimated the one hundred year flood elevation of Silver Lake as 530 feet (City of Everett datum). Because the area is not designated as being in the Flood fringe, Section 30.040.C. of the Zoning Code does not apply (Development Standards tor Pertnitted Uses in the Urban and Rural Flood Fringe Districts). However, the City recommends that all structures be elevated to two feet above the estimated one hundred year flood elevation (530 feet). The general regulations listed in the SMMP relate to h+gh energy environments, such as those along nvers where rip-rapping, dikes, or levees are proposed. The flood proofing proposed for the Casper Creek proposal includes elevation of structures to 532 feet or higher �s part of the overall grading proposal for the site. Conclusion: The general regulations listed in the SMMP do not apply to the proposal. However, the City recommends that all structures be elevated to two feet above the estimated one hundred year flood elevatior�. The proposed grading plan shows the fir,ished floor elevation of all strw:tures is higher than 532 feet.
