Chicago’s West Loop is now home to a new two-in-one hotel located at 118 North Jefferson Street. The 23-story building project features a 210-room Hampton Inn and a 128-room Homewood Suites. Other complex amenities include a parking garage, pool, retail space and an on-site restaurant.
EEA consultants were retained by VOA Associates to secure all necessary city permits and design customized stormwater systems to meet unique site challenges.
According to Chicago City code, because the building filled less than 85% of the lot, the site required additional stormwater detention. To ensure these requirements didn’t detract from the appearance of the hotel’s entrance and functionality of the planned outdoor restaurant deck, EEA worked with the architect to design a trench drain system. The system’s narrow basins and longer slope route water away from the building while keeping pavement relatively flat.
During development, EEA engineers tailored the design of the stormwater tank system below the building to fit the contractor’s specific building requests. To avoid impacting adjacent building’s foundations, both parties carefully selected a tank with a larger capacity and depth.
