Drainage Enhancements

under construction

This project proposes to reduce the incidents and magnitude of coastal storm related flooding at: 1. Meadowbrook State Parkway under Merrick Road in the Town of Hempstead, Nassau County. The work includes hydraulically separating the Meadowbrook Parkway low point located under the Merrick Road bridge (approximately 1000 feet roadway length) with an earth embankment, check valves, rerouting of drainage lines, and installing a Pump Station to drain the isolated area low point.  Additional work includes installing underground drains to dewater the permanently soggy grass shoulder.  2. Wantagh State Parkway under Bay Parkway in the Town of Hempstead, Nassau County. The work involves hydraulically separating the Wantagh Parkway low point located under the Bay Parkway bridge (approximately 1000 feet roadway length) with check valves, rerouting of drainage lines, and installing a Pump Station to drain the isolated area low point.  Additional work includes installing underground drains to dewater the permanently soggy grass shoulder and installing a coastline structure to protect outfall pipes that are repeatedly damaged from coastal storms.
