Overview

This project involved replacing the existing asphalt of two different cul-de-sacs in Woodbury with porous pavers. Macbeth Court and Juliet Drive receive significant drainage from upstream areas, including lawns, buildings, driveways, and streets. Prior to project implementation, all of this runoff entered storm sewers and flowed untreated into Carver Lake.

The porous pavement is made of interlocking concrete paving stones. Small spaces between the pavers allow stormwater to seep into a rock base storage layer and then into the ground where phosphorous and other nutrients are filtered out naturally. This infiltrated stormwater reduces the volume of runoff and nutrient loads reaching Carver Lake.
