Project Description

Delaware City faces the threat of flooding from intense rainfall combined with high tidal surge.  Duffield Associates managed the planning, design, funding acquisition, permitting and construction review of interdependent stormwater system improvements for the City’s flood mitigation project.  The project included replacing and extending an existing stormwater outfall, underground piping conveyance and storage improvements and an 18,000 gpm stormwater pumping station to mitigate chronic flooding.  The City now maintains a robust, automated collection and pumping system to mitigate flooding in its downtown historic area.
