Trinity Ridge Estates - Gig Harbor, Washington

Consisted of 30 single-family residential units on approximately 30.7 acres. The project is located off 74th Street NW near Gig Harbor. A new waterline was constructed to the site. Each lot was designed with individual on-site septic systems. Each of the three on-site stormwater systems had its own conveyance pipe, infiltration pond and biofiltration swale. Biofilters were located on-site to remove the pollutants generated from site traffic prior to conveying the clean water to the nearest infiltration pond. Sitts & Hill provided the documents necessary to obtain the gate permit and designed the roadway to allow emergency vehicles to access the site for width and turning radius.
