CPWG Stormwater experts developed solutions to flooding around the Bonnie Brook Pumping Station.
CCPWG Experts Analyzed Data From:
- USGS Quadrangles
- Soils Maps
- Floodplain Maps
- Surrounding Subdivision Construction Plans
- Shingle Creek Stormwater Management Master Plan
- Pump Station As-builts and pump curves
CPWG Stormwater Engineers:
- Inspected The Basin, Inlets, and Stormwater System
- Created an ICPR Existing Conditions Stormwater Model
- Assessed Potential Street and Housing Flooding
CPWG Used the Data to:
- Prepare a Preliminary Engineering Report
- Designed Improvements to the Holding Pond
- Prepared Construction Plans
- Prepare Operation Procedures
Bonnie Brook Pumping Station
Orange County, FL
CPWG Stormwater Specialists were engaged by Orange County to assess the Bonnie Brook Pumping Station. The Bonnie Brook Pump Station Pond, PS-029, is located in south-central Orange County, within the Shingle Creek Watershed. The purpose of this project was to provide a solution that would alleviate the minor flooding conditions that existed in the roads adjacent to the previous concrete pond.
Our Stormwater Specialists evaluated the current conditions around the proposed pumping station. They collected and reviewed maps and past studies concerning the area. The maps included USGS Quadrangles, soils maps, floodplain maps and existing right-of-way maps. Also reviewed were the construction plans for the surrounding subdivision, the Stormwater Management Master Plan for Shingle Creek, and Pump Station As-builts and pump curves
Evaluate Existing System:
Our engineers completed a site recon to visually inspect the basin, inlets, and associated stormwater system to create an inventory of the primary existing stormwater system within the project area. They prepared an existing conditions stormwater model using Interconnected Channel and Pond Routing (ICPR) and documented the predicted peak stages with the pump station pond. 10-year, 24-hour storm event using the Orange County rainfall distribution was analyzed and used to evaluate potential street flooding. The model demonstrated street, garage, and potential housing flooding.
Preliminary Engineering Report
CPWG Engineers Prepared a Preliminary Engineering Report with three solutions for the drainage problems in this area. The solutions included 1) enlarge the existing concrete pond without relocating the generator; 2) enlarge the existing concrete pond and relocate the generator; 3) enlarge concrete pond and add third pump station. Each solution contained information on permitting requirements/costs, right-of-way needs/costs, and construction costs. The Orange County Officials made their selection based on the effectiveness of rehabilitation and expansion of the holding pond on further reducing the flood stage.
The CPWG Design Team began design improvements to the holding pond and pump system as determined by the evaluation. Our Engineers prepared construction plans and operation procedures for the upgraded pond and station design. The plans included submittals at the 60%, 90%, 100% and final levels of completion.
Client Staff Assistance
To bolster our client’s staff, CPWG members attended the Pre-Bid Construction Meeting and the Pre-Construction Conference. During the 13-week Construction Phase members of our team attended each Construction Meeting to assist with project scheduling and certification.
