Traditionally, stormwater from roads has been conveyed directly to surface waterbodies in Suffolk County. This was done in an effort to keep roads clear during storms; as road flooding causes dangerous conditions for motorists. However, this diversion of stormwater has resulted in stormwater pollutants entering our waterbodies.

To prevent further discharges of stormwater pollutants, Suffolk County DPW has set goals to remediate traditional measures by treating and/or diverting stormwater before discharge. To accomplish these goals, the DPW has completed several stormwater pollution prevention projects, all of which address the prevention, reduction, or elimination of pollutants to Priority Waterbodies.
