Windsor Engineers provided comprehensive planning and engineering services for a multifamily development project in Woodland, Washington. The project involved a challenging site with wetlands, steep access up a hillside with landslide potential, and extension of utilities to the site. The stormwater component of the project included self performed infiltration testing at both high (drier and sloped property) and low (wetter area near flood plain) elevations. The project determined how to best collect, convey, detain, and treat stormwater from the streets, buildings, parking areas and sidewalks, that is proposed on the 11.9 acre property. Other planning services included street and utility analysis, grading, access road layout, apartment configuration, and coordination with the City.
