Stormwater
Taylor Engineering incorporates its surface water modeling, GIS expertise, and structural engineering into a powerful stormwater management team with experience in large, basin-wide studies and smaller-scale studies that focus on a single urban development. These studies incorporate surface hydrology, system hydraulics, floodplain delineation, BMP analysis and design, hydraulic structure analysis and design, water quality modeling, and sediment transport analysis. To accomplish this work, we use the latest modeling packages including dynamic and two-dimensional analysis with support from the latest pre- and post-production GIS tools.

Lake Okeechobee Steel Sheet Pile Water Control Structure at S-65E
Taylor Engineering developed an emergency solution for low water levels in Lake Okeechobee. The lack of water depth created forces capable of undermining S-65E, the water control structure located at the southern end of the Kissimmee River. Such a condition could cause structural failure, and trigger severe flooding to upstream and downstream residential and agricultural properties. The final, award-winning design alternative consists of a 200-foot-wide underwater weir approximately 4,000 feet downstream of the S-65E structure. Eight connected cellular sheet pile structures guide the flow over the weir. A 200-foot x 90-foot x 8-foot-thick concrete apron provides erosion protection in the most turbulent area. Riprap placed along the canal bottom several hundred feet upstream and downstream of the structure provides additional erosion and scour protection.
Leading-edge Solutions
- Completed hydraulic and structural analysis, construction document preparation, and bidding within two-and-a-half months from notice to proceed to allow project construction completion before hurricane season
- Communicated frequently with client to ensure project remained on schedule
- Prevented catastrophic flooding of homes, communities, and agricultural areas when Tropical Storm Fay struck the area two weeks after construction
Crystal Springs Drainage Project and Conceptual Design
This residential area experiences regular flooding during high return frequency storm events. This phase of the Crystal Springs study focuses on conceptual design solutions to remedy these localized flooding concerns. In general, the solutions offered sought to reduce flooding problems by improving stormwater flows in the upstream portion of the project area for a 25-year return period storm and minimizing the increase in surface water elevation downstream of the project area. Additionally, the project sought to find solutions that reduce maintenance efforts for the City of Jacksonville.
Leading-edge Solutions
- Developed and evaluated five stormwater system alternatives to remedy existing flooding concerns
- Applied advanced numerical modeling tools to assess existing and alternative conditions
- Identified most beneficial alternative considering engineering performance, construction and maintenance costs, and permitting challenges
Sawgrass Stormwater Assessment & Management Plan
On behalf of the resident homeowners’ association, Taylor Engineering assessed the Sawgrass stormwater system to determine its ability to manage stormwater runoff, maintain acceptable water quality, provide flood control, and to develop basin management recommendations to reduce sediment and pollutant loading and potential flooding. The system, experiencing significant shoaling and water quality problems, comprises 100+ interconnected lakes discharged by two pump stations to serve the exclusive 2,400-acre Sawgrass community.
Leading-edge Solutions
- Collected field data and conducted personnel interviews to develop a base understanding of system functionality and key operational parameters
- Applied numerical modeling to simulate the system’s response to 25- and 100-year, 24-hour rainfall events
- Recommended multiphase approach to quantify system capacity, identify flood control improvements, and maintain acceptable water quality
- Suggested innovative methods to reduce aquatic growth in selected lakes
- Recommended lake monitoring and initiation of a long-range mapping and surveying program to document conditions throughout the system
