GSI Installation

Rain Garden

Project Location: Alma E. Pagel School
Project Construction: A rain garden will be implemented in the south-east grassed area facing Benham Hill Road collecting stormwater runoff from the adjacent driveway of Alma E. Pagel School.

The Runoff Reduction Report

This report includes recommendations for green stormwater infrastructure practices at 4 sites in the town of West Haven. Each site is displayed with an ArcGIS map of the recommended practice, detailed description of our recommendations, and an informational table. Each table shows an estimated drainage area, our recommended green infrastructure, annual gallons of runoff treated, nitrogen and phosphorus pollution reduction amounts, and the suggested size of each practice. These estimations were calculated based on the drainage area, annual rainfall estimates specific to Connecticut, and literature export values.
