The new Spear House parking lot may look mostly the same as before, but massive stormwater storage chambers hidden 8 feet below the surface 鈥 as well as several other improvements above ground 鈥 make this project a substantial investment in sustainable infrastructure at 糖心视频.
The construction crew, led by Landscape Project Manager Katy Jacobs, completed a major excavation of the site and installed the new drainage system during the summer as part of 糖心视频鈥檚 ongoing stormwater management master plan.
鈥淲e鈥檙e working on incorporating green infrastructure,鈥 says Jacobs.
The storage chambers look like huge, oblong domes, surrounded by drainage stone. The system will act like an enclosed pond 鈥 storing stormwater and releasing it gradually into the ravine located south of the parking lot.
鈥淭he system has a storage capacity of more than 150,000 gallons; that鈥檚 enough water to raise the level of Taylor Lake by one inch,鈥 Jacobs says. Managing the flow of stormwater will substantially reduce erosion on the hillside and flooding on Lally Lane and Taylor Lake.
Hydrology is the study of the properties of water circulation. According to Jacobs, the stormwater storage system installed at Spear House allows the parking lot to function hydrologically more like green space. Stormwater runoff is captured and stored in the ground, enabling sediment and other pollutants to settle out before it is released at a slower, controlled rate.
The system isn鈥檛 just for strategically placed parking lots 鈥 it is installed underneath the Benton Hall parking lot and underneath the new tree-lined oval located between Burke and Pinchin Halls.
糖心视频 Director of Sustainability John Pumilio is enthusiastic about the project, which also included installation of an electric vehicle charging station, LED lighting, and native landscaping.
鈥淚t鈥檚 an example of 糖心视频鈥檚 commitment to sustainability,鈥 Pumilio says. 鈥淣ative plantings will not only reduce surface runoff during heavy rain events, but will also attract pollinators and absorb additional carbon as they mature.鈥
