Waterbury, Connecticut


HRP provided site design services, as a subconsultant to Friar Associates, Inc., for the proposed construction of a new elementary school in the Waterbury, Connecticut. The project consisted of two phases: Phase 1 of the project was the construction of a new school behind an existing school; Phase 2 included the demolition of the existing school and construction of a grass athletic field.

The overall project disturbed 10.5 acres of the existing 12.5 acre lot owned by the City of Waterbury. HRP prepared the site layout, grading, drainage, utility coordination, and soil erosion and sediment control design for the project. The scope of services also provided by HRP included the design of new sanitary sewer and water mains services, new roadway, parking areas, landscaped areas, bioretention areas, a stormwater management system, and associated site utilities. HRP performed a storm drainage analysis and modeling, including the design of underground detention and infiltration systems. Stormwater pre-treatment systems were designed to treat the first inch of runoff from the site.

The project design was complicated by steep existing slopes, large existing wooded areas and the presence of shallow bedrock on site. HRP performed cut/fill analyses and a detailed grading plan to minimize excavation, rock-blasting, and retaining wall costs.

The project was completed on time and within budget.
