The new development included demolition of the existing school building, parking, sidewalks, and associated utilities and construction of a new building, courtyards, asphalt parking areas, storm drainage, and utilities.
AHBL surveyors completed a topographic survey of the Shorewood Elementary School site and neighboring streets for design purposes. Civil engineering services included several retaining walls, ramps and stairs to allow for site access, parking, bus drop off and other programmatic requirements. Other civil improvements included water main and sewer main extensions, underground stormwater detention systems, offsite street improvements and use of Low Impact Development (LID) practices for the site development. The use of LID allowed AHBL to minimize the size of stormwater quality and quantity control facilities and mitigate the impacts of the new school on downstream storm drainage systems. Sand filters were used to treat stormwater runoff from parking areas before discharging from the site. Stormwater runoff from pedestrian plaza areas was routed into rain gardens to help reduce the site’s total stormwater runoff. The use of rain gardens and sand filters allowed AHBL to save the District money by minimizing the cost of stormwater detention and treatment.
