This project included a reconstructed stormwater detention facility near the intersection of 38th Street and Holly Street. The improvements included grading to provide required flood storage volume, replacing a damaged spillway, installing a new diversion structure, and incorporating a new trail and landscaping amenities. Structural design included a new diversion structure to intercept storm drainage from an existing 66-inch storm drain under Holly Street, a new pond inlet structure, a water quality outlet structure, and a 4-span reinforced concrete box culvert to carry a pedestrian trail over a new concrete drop structure. The drop structure included decorative concrete paving and welded wire mesh gabions incorporated into the wingwalls at each drop location.
