9610 19th Avenue SE <br /> July 27, 2012 <br /> Revised September 18, 2012 <br /> Page 3 <br /> t. PROJECT DESCRIPTION <br /> The existing 76,096 square foot (1.75 acre) site is located at 9606 and 9610 19th Avenue SE. <br /> Currently there is an old McDonalds Restaurant and cell tower on the site. The restaurant <br /> will be demolished and the cell tower will remain. Two storage buildings will be constructed <br /> on the site along with new parking and drive lanes, stormwater flow control and treatment <br /> infrastructure and domestic and fire sprinkler systems. <br /> The existing drainage infrastructure for the McDonalds Restaurant drains through a <br /> stormwater detention vault, an open swale, and into a 12-inch ductile iron pipe flowing <br /> westerly to the easterly edge of Interstate 5 and into a wetland. <br /> There is no off-site upstream drainage flowing onto the site. 19th Avenue SE cuts off <br /> drainage from the east, and existing development to the north and south control drainage in <br /> these areas. <br /> In accordance with the 2010 City of Everett Stormwater Management Manual the proposed <br /> drainage system on-site is designed using the Santa Barbara Urban Hydrograph method <br /> because the area of exposed subgrade on the site is less than one acre. <br /> Ph: (206)403-0933, email:jayd@deckerce.com <br />
