Flamingo Ditch

GRAEF was commissioned by the City of Venice to provide civil and coastal engineering services for design, engineering, permitting and construction documents for new stormwater discharge pipelines at the existing Flamingo Ditch beach outfall. GRAEF conducted all planning, design, permitting and engineering services for the pump station, treatment systems, directional drilling, diffuser and anchoring system for a new pipeline that will re-route the existing beach stormwater discharge to a deep water location approximately 1,000 ft into the Gulf of Mexico. The project will alleviate the City’s flooding problems due to obstruction of the existing outfalls from sand build-up and periodic water quality violations along Venice beaches.
