CG Engineering provided civil and structural engineering for a new Mercedes Benz dealership in the City of Lynnwood. The building is one-story, approximately 42,000 square feet with a showroom, a service area and a small mezzanine. The showroom area is a 35 foot tall steel framed structure with a metal deck roof. The site is approximately 3.5 acres and has a critical area. To handle increased flows due to the addition of impervious areas, a structural detention vault was designed. To minimize the size and cost of the vault, rain gardens were designed to account for significant portions of the site runoff.
