1. PROJECT OVERVIEW <br /> This document is intended to provide engineering information necessary to support the <br /> building permit application to the City of Everett for the proposed Single-Family Residence <br /> (SFR) and concrete driveway on this lot. The site is located at 4805 Bayview Lane, <br /> Everett, WA 98258, refer to Figure 1 for a vicinity map. This site takes access from the <br /> existing roadway to the west. The parcel area is approximately 0.21 acres. The existing <br /> site consists of lawn. The slope of the site, in the area of disturbance, is flat and averages <br /> less than 5 percent down to the northwest. The new SFR will be located approximately 29 <br /> feet from the western property line. <br /> This project proposes to construct more than 2,000 sf and less than 5,000 sf of new and <br /> replaced impervious surfaces. Therefore, Minimum Requirements 1-5 apply to all of the <br /> new and replaced impervious surfaces for this project along with all the converted <br /> vegetated areas. The proposed impervious surfaces will be dispersed on-site. This <br /> project has been designed to meet the DOE Stormwater Management Manual for Western <br /> Washington requirements. <br /> Figures 2 & 3 are provided to show the existing and developed basins and runoff <br /> conditions for this site. The runoff in the existing conditions sheet flows over vegetated <br /> surfaces to the northwest toward the northern property line. <br /> Due to the size of this project, Minimum Requirements 1-5 apply to the proposed drainage <br /> design as noted above. The stormwater design has been laid out to meet the DOE 2012 <br /> manual with 2014 updates. <br /> Bayview SFR 18-0806 <br /> August 2018 Page 4 <br />
