Laurel Commons is a privately owned and maintained facility located in Toms River, Ocean County, New Jersey. When built, the property was equipped with a standard grassed detention basin intended for stormwater drainage storage. This traditional basin method would hold stagnant water for long periods of time promoting unsightly conditions and a breeding ground for mosquitos. The drainage area to this grassed basin is approximately 5 acres. The proposed conditions included retrofitting this basin area to provide better infiltration and overall water quality while improving aesthetics. In order to achieve that, the grassed detention basin was converted into a naturalized bio-retention basin.
Unlike the traditional stormwater basin, stormwater directed to this bio-retention basin percolates through the system where it is treated by a number of physical, chemical, and biological processes. The native plants used are adapted for high water retention resulting in little to no flooding after such a project is implemented. This project's total area of disturbance was less than 30,000 square feet. To ensure success, additional measures included implementing weirs and adding "No Mow" zones. Overall, this basin retrofit project resulted in increased overall water quality and aesthetics of this area, and decreased flooding events.
