The Wisconsin Place, located on the border of Montgomery County and the District of Columbia, is an 8-acre urban center. The property consists of 300,000 SF of retail, 450,000 SF of office space, 300,000 SF of residential, a 17,200 SF community center, and a multi-level underground 1,600-space parking garage. Engineering this site for construction presented many difficulties, one of which was coordinating design and regulatory approval from three different jurisdictional agencies. Bounded on several sides by major arterial roads, including a Maryland State Highway, maintenance-of-traffic was of paramount importance to the success of the project yet posed ongoing challenges as the project progressed from one phase to the next. Efficient stormwater management and the balance of green space was also a major engineering concern because of the high traffic location.
The Soltesz Solution
Understanding the potential scheduling impacts of the maintenance-of-traffic issues, the Soltesz team prioritized traffic coordination. The team worked diligently and closely with DCDOT, MC DPW&T, MCDPS and MDSHA as well as local neighborhood homeowner associations to obtain all of the necessary approvals and permits to keep the aggressive project on schedule. Maintenance-of-traffic plans were phased and coordinated with the three different agencies to ensure safe traffic and pedestrian flow around the project throughout the three-year construction lifespan.
To address the stormwater management within such a tight urban space, Soltesz designed two underground water quality and quantity detention structures. Neighborhood parks – designed and built directly above these stormwater management devices – addressed the balance of the green space on the site. The two water quality structures, also designed around the underground garage, were built in different phases to minimize disturbances to the area. This solution allowed for all stormwater to be treated on site and still met the green space and public amenities requirements, which were integral to the client’s vision of the development.
