Engineers • Surveyors • Subsurface Utility Engineering 3D Subsurface Imaging • Utility Coordination implementation of new stormwater management systems and does not include major roadway re -grading or full reconstruction. CAS will also investigate the possibilities of providing an offsite discharge connection as part of this proposal but the scope of work in this proposal will be limited to improvements on SW 2nd street as described. CAS services include surveying, utility locates services, engineering design, permitting, bidding and negotiating services, construction management services and final certifications through project closeout. Protect Challenges & Approach: The project's existing site conditions include low site grade elevations, lack of available land space and low soil permeability rates making it challenging to implement new stormwater management design elements such as swales, retention areas and exfiltration trench. Additional challenges included congested corridors with various existing utilities that made it difficult to accommodate proposed exfiltration trenches within the road right of ways. The project design approach included maximizing offsite discharge rates to maximum allowable rates using two existing outfalls, creating new Swale areas where possible and implementing two water quality control vortex separator devices. The proposed water quality devices provided the full water quality treatment volume required for the project area, greatly exceeding the existing water quality treatment being provided. The design also included improving stormwater conveyance by expanding the current drainage system to encompass the entire drainage areas through new interconnected catch basins and increasing stormwater pipe sizes to both outfalls. Design Cost: $143,833 Construction Cost Estimate: TBD Town of Pembroke Park - SW 25th Street Stormwater Improvements, Pembroke Park, Florida Status: On-going (Design Phase) Prime Consultant: CAS Key CAS Staff: Stephen C. Smith, James R. Orth, Frank Vilar, Robert D. Keener, Tony Gomes, William Tanto Scope of Work: Multi -phase stormwater improvement project totaling 14.34 acres. Project scope was survey, hydraulic modeling, design, construction contract development and bidding services for Phase I and II which was a 2.44 acre drainage sub basin area. The purpose of the project was to alleviate flooding in the Town of Pembroke Park by improving hydraulic conveyance throughout the existing stormwater drainage system serving the 14.34 acre study area. A hydraulic analysis to determine the acceptable level of service to the Town was performed by the development of an ICPR model for the project area. In order to develop the ICPR model, a comprehensive review of existing survey and utility information, available record drawings, aerial photography and field investigations were performed. After the model was completed, proposed recommendations were made for upsizing the existing stormwater drainage pipes by analyzing the ICPR results for reduction in peak stages and flood duration times in the pre and post conditions. Existing discharge pipes were upsized from 24" to new 54" diameter drainage pipes.
