1. Introduction <br />The Kasch Park Repaving project consists of replacement of approximately 4.3 acres of existing asphalt in the <br />Community Transit parking lot area. Community Transit is located at 2300 Kasch Park Road, Everett, WA <br />98204. All stormwater facilities will meet the requirements of the 2012 Department of Ecology's (DOE) <br />Stormwater Management Manual for Western Washington (SMMWW), as well as the 2010 City of Everett <br />(COE) Stormwater Management Manual (SMM). The site uses a pump to route water that has already been <br />detained onsite in a detention vault to a bioswale south of the pavement footprint for water quality treatment. <br />This bioswale was sized to treat an estimated water quality volume of 0.40 cfs (see Appendix B for the original <br />water quality calculations). However, it has been found that the pump is actually pumping 0.62 cfs (see <br />Appendix C for the pumping analysis). The upgrades to the water quality treatment process are therefore <br />treating 1.5 times more water than actually required. <br />The site is comprised of a single 18.1-acre parcel. The parcel is bound to the north and east by Kasch Park <br />Road (Kasch Park Road runs west to east and then curves south and runs along the eastern property line). <br />Adjacent to the western property boundary is the Sno-isle Skills Center and to the south is Woodstone <br />Industries, Inc. GeoEngineers also noted small wetland areas on site, to the southwest, south, and east of the <br />pavement areas (see the Critical Area Review document, submitted by GeoEngineers under separate cover). <br />The site is located within Everett City limits. (see Figure 1-1). <br />1 000 <br />`* CITY <br />�S <br />+ EVERETETT <br />f <br />76th 51 SW <br />POSSESSION <br />SOUND <br />"^a1- 16ih 5I5W <br />1 (� <br />RO <br />a' <br />i.,C <br />801h St SW % <br />B nq Comrrr ml <br />Aapianea <br />BOIN St SW <br />BItrRSW <br />Y <br />i` <br />s„ <br />Boetng Fwy i <br />Dam 5t SW 516j ism' <br />Future of fight Awattort <br />eni <br />W Cawno Rd <br />- Center 6 Soetnq Tour <br />I <br />i <br />88th St SW 88m St ,S�w <br />K—h <br />Poo Nd <br />S <br />f lS <br />Sno-Itde SM Center • Walw lied Gail <br />y <br />Course r 90m 5r SW <br />91nd SI SW �� <br />� <br />f 91 s1R5W <br />3 6 <br />Kasch.Perk <br />98rd � S1 SW <br />r <br />SITE <br />LOCATION <br />gg 8 <br />"4 fj <br />I00th St SW <br />Pame twld Arpo-t <br />107rd St SW <br />� rvi <br />5 <br />90 106th St Sw <br />Figure 1-1: Vicinity Map <br />Temporary Erosion/Sedimentation and Drainage Report — Community Transit <br />1 <br />
