The proposed grades require construction of a fill embankment up to approximately 9-10 feet above existing ground surface levels. Stripping approximately 1.5 feet of organic native material. In conjunction with filling the site, Team Nelson constructed a 1,300 foot extension to 156th St NE including a 40-foot-wide by 115-foot-long bridge structure across Hayho Creek, two sperate bores beneath Hayho Creek that included a 24” bore for Sewer and 20” bore for Water. A native riparian buffer restoration to be implemented along 8,105 square feet of stream in addition to 190,000 square feet of buffer enhancement.
