City of West Palm Beach Stormwater Master Plan

Jones Edmunds was part of a team selected by the City of West Palm Beach to develop a clear, comprehensive, and forward-looking framework that encompasses the City’s existing stormwater management program. This project included services to investigate key components of stormwater as it relates to the City of West Palm Beach. We established goals and a foundation for future policy decisions, and developed a final product that will help the City guide its stormwater management program for the next 30 years.

Pinellas County Cross Bayou Watershed Management Plan

Jones Edmunds developed a Watershed Management Plan (WMP) for the Cross Bayou Watershed. The project consisted of selected elements from SWFWMD’s Watershed Management Plan Guidelines & Specifications. Primary tasks included creation of digital topographic information, development of a watershed evaluation report, identification of surveys to be performed and preliminary junction/reach coverage development, model simulations, BMP analysis, floodplain mapping and a surface water resource assessment. The watershed is approximately 13 square miles and connects across to both coasts of the Pinellas County peninsula. We used existing stormwater asset inventory data from the County, the City of Seminole, and the City of Largo – all in different formats – to reduce field reconnaissance and survey requirements and to better define local drainage patterns. The floodplain model was developed in ICPR and had to consider significant inflows from two canals outside of the watershed as well as other intermittent connections with surrounding watersheds. Development of the model schematic and model parameterization were expedited through extensive use of GIS-model automation tools and our standard operating procedures for applying the tools. The tools made extensive use of LiDAR data and other site plan information that superseded the LiDAR data in specific locations to develop a date-certain terrain, soils and land use layers, stormwater infrastructure geodatabases, and high-resolution multispectral imagery. The model was calibrated and verified at two USGS gage locations as well as at other high water mark locations throughout the watershed for a recent very large storm event. NEXRAD data were used for the verification, and local rain gage data were used to corroborate the NEXRAD data.

Brevard County West Melbourne Stormwater Quality Retrofit

Jones Edmunds is providing professional design services for water quality improvements to previously developed storm drainage systems in West Melbourne, Florida. The scope includes retrofitting 10 sites to install proposed nutrient separating baffle boxes. The project is receiving funding through the 319 Grant Program and is for the west part of West Melbourne. The Brevard County Stormwater Utility Department is managing the project based on the Department’s interlocal agreement.

Town of Melbourne Beach Stormwater Drainage Improvements

Jones Edmunds provided engineering, stormwater modeling, permitting, and construction-phase services for multiple stormwater drainage improvement projects for the Town of Melbourne Beach. The goal of the drainage improvement projects was to reduce flooding in the target basins. The improvement projects involved installing baffle boxes, bioretention systems, numerous swales, and flood improvement elements for the beachside community. The highlight of the project was the Sunset Boulevard Bioretention Park. The improvements consisted of regrading Sunset Boulevard to drain to the median, constructing approximately 1,080 LF of planted bioretention swales in the Sunset Boulevard median between Pine Street and Riverside Drive, constructing shallow grassed swales outside the drive lanes between Pine Street and Riverside Drive, and constructing six curb inlets and approximately 780 LF of new culvert. No overflow from the system was observed in October 2011 when a tropical system dropped more than 8 inches of rainfall.

City of Gainesville Duval Regional Stormwater Park

Jones Edmunds provided permitting, design, and construction contract documents for the Duval Regional Stormwater Park. This stormwater retrofit project addresses the Newnan’s Lake nutrient TMDL and serves multiple purposes for a Florida Front Porch Community grant. The project provides water quality treatment for approximately 70 acres of existing urban development. The primary treatment component is a 2-acre wet detention pond. A Suntree nutrient separating baffle box pretreats the inflow to the wet detention pond. Treated discharge from the pond rehydrates a downstream wetland impacted by nearby ditching. The 26-acre project area also includes a nature trail and a parking area. Urban development in the vicinity of this project has redirected the surface water around the site through the existing storm sewer and ditching network. The project includes constructing an interceptor pipe that connects the nearby storm sewer on NE 8th Avenue to the site. We designed the constructed pond to resemble a natural lake as closely as possible by having shorelines with gently curving forms and varying basin slopes. Native species already on site or that enhance the diversity of existing wetlands populate the littoral zone. The stormwater pond was located to avoid wetlands and minimize the loss of significant trees. In addition, we designed a 2700-foot ADA-compliant nature path with boardwalks spanning existing wetlands and paved sections in uplands. The path traverses the park property through upland forest, over wetlands, and along the wet detention pond. The project received $500,000 of 319(h) grant funding. Jones Edmunds developed pollutant loading reduction calculations for pre- and post-project conditions with a focus on total phosphorus, which is the pollutant of concern for the Newnan’s Lake. Specifically, a portion of the load reduction can help with redevelopment projects in the watershed. To help administer the load reduction credits, we developed an easy-to-use spreadsheet model that calculates new loads from redevelopment in a manner consistent with the original calculations. This premiere stormwater design is commonly referenced in the Florida stormwater community. All in all, it demonstrates Jones Edmunds’ ability to combine practical stormwater treatment design elements with multi-use park facilities. This project also received a high level of public support and utilization by the local residents.

Stormwater and Watershed Management

Stormwater is one of the most valuable resources in our communities. It plays an important role in supporting ecological health, recreational opportunities, aesthetics of our communities, and water supply. It also has the potential to cause flooding, create safety hazards, and damage our infrastructure. Our passion for understanding the roles that stormwater plays in both the natural and constructed environments and developing innovative ways to manage and protect this resource aligns with our clients’ desire to improve their communities and make them safer, more sustainable, and resilient places to live. We offer the following services:
