Basin Drive Stormwater Pump Station Rehabilitation City of Delray Beach

The Basin Drive stormwater pump station is located in Delray Beach, Florida. This is a 3,000gpm stormwater flood control pump station owned and operated by the City of Delray Beach. The Basin Drive coastal residential area suffers from periodic inundation caused by a combination of an undersized stormwater management system and the effect of Sea Level Rise. During a 2016 King Tide, Intracoastal Waterway water spilled over the seawall and into the Basin Drive area. WGI performed an evaluation of the stormwater pump station, and associated drainage basin storm sewer collection system, and prepared a summary report detailing the results of the evaluation. The evaluation included a review of regulatory permit conditions, City objectives, field data collection (LiDAR survey), hydraulic and hydrologic (H&H) modeling, and a functional assessment of the pump station components. A pump integrity assessment was performed to identify mechanical, structural, and hydraulic deficiencies, including a Sea Level Rise H&H modeling study to quantify flooding caused by increasing SLR. The technical evaluation report included a description of the system deficiencies, recommended upgrades, preparation of conceptual level upgrade design, and preparation of an engineer’s opinion of probable construction costs.
