99th Pl. NE/100th Ave. NE (CIP Project#: NM 0060 000)CIP Project DescriptionInstall ~1350 linear ft. of curb, gutter, and sidewalk and five-foot planter strip in some areas. Available right-of-way and steep slopes maypreclude the planter strip in some areas. ADA compliant wheelchair ramps will also be required at cross-walk locations.LID Opportunities and Benefits• Installing porous pavement sidewalks will reduce the runoff from the shoulders.• Rain gardens can provide flow attenuation and stormwater treatment of roadway runoff.Creating singular or a series of rain gardens near the existing catch basins will attenuate peak flows and treat the stormwater beforedischarging to Lake Washington and the adjacent wetlands. Based on the location of the property lines and the edge of the travel lanes, thereis available right-of-way to install these LID elements to benefit stormwater and pedestrian safety.General existing conditions & considerations• Road undulates along longitudinal axis creating drainage pockets(see profile to right)• Road cross slope consistently slopes to west• Some structures along the west side of the road are lower than theroadway• Sub-basins may drive up project costsProfile view of 99th Pl./100th Ave. NE99th Pl.
