6CES Consultants ● City of Sunny Isles Beach RFQ No. 18-11-01 APPROACHPROJECT UNDERSTANDING & The Golden Shores neighborhood at the north end of the City of Sunny Isles Beach is a single-family neighborhood that has experienced repeated flooding events resulting from seasonal tides, storm events or both. The neighborhood most recently experienced flooding due to Hurricane Irma, as well as from seasonal rainfall months following the hurricane. The City has been looking at a comple1te rehabilitation of its pumping efficiency to significantly improve the evacuation of water during these existing flood conditions and as such maintain the level of service for its residents. We understand the Golden Shores Pump Station is the pump station that serves the Golden Shores Neighborhood. We also understand from this RFQ, that the City has limited information on the efficiency and capacity of this pump station, as specific technical information related to the Pump Station and City Drainage Atlas were not included as part of this RFQ. The City is looking for a qualified consultant to provide the required professional services for rehabilitation of the Golden Shores pump station through analysis of condition assessments and performance evaluations. By way of background and research of past records, our team has learned that the Golden Shores Pump Station was a significant element transferred to Sunny Isles Beach as part of the original stormwater Interlocal agreement with Miami Dade County. We also understand that the pump station encompasses a dual disposal system that includes a combination of gravity discharge via an outfall into Biscayne Bay and surficial vertical discharge via pressurized wells. We derive this primarily from our review of past maintenance efforts conducted by the City, which leads us to derive that during its lifetime the pump station has gone through considerable rehabilitation resulting from operational inefficiencies. Historic records point out that the city conducted repairs on the well flap valves worn out by well up-flow as well as discreet lining repairs of the well and associated conveyance elements. The City also conducted one major overhaul of the Pump Station that was completed in 2003 along with a drainage system retrofit within the Golden Shores Neighborhood. We understand that according to a request made by the City of Sunny Isles Beach to the Florida Senate, the City of Sunny Isles Beach will also like to redirect part of the flows from the outfall to deep injector wells. This will be performed by re- establishing the existing wells. Finally, the City will like to have the ability to monitor and operate the pump station remotely utilizing a Remote Terminal Unit (RTU). Based on the information stated above, we can deduce that although the Pump Station remains fully operational to meet adequate levels of service, its hydraulic functionality would need to be evaluated in the backdrop of a whole new set of parameters, including but not limited to land use, updated stormwater regulatory criteria, increased flooding events, groundwater rise, brackish water intrusion, etc. There is also a whole slew of potential environmental stressors that could impact the pump station’s functionality and would need to be considered when establishing a proper benchmark. CES has a deep bench of professional engineers. There is a sizable opportunity to build resiliency by delivering sustainable infrastructure while mitigating impacts to the current
