We have a team of professionals that are specifically dedicated to all aspects of surface water management analysis, design and permitting. The dedicated nature of this team allows them to stay up to date on current issues and advancements related to surface water management. They are able to provide a wide variety of services including surface water master planning; retrofit analysis and design; treatment system design; permitting; hydrologic, hydraulic and water quality monitoring; and water quality, flow and stage monitoring.
Verandah is large mixed us development located in eastern Lee County. It includes single and multi-family residential units, commercial space and 36 holes of golf. Our surface water team handled the design and permitting of the Verandah surface water management system. Team members begin working on the project during the rezoning process through Lee County and continued on the project through State, Federal and local permitting and subsequent permit modifications.
This was an especially difficult project due its close proximity to the Orange River and the number of wetland systems that traverse the project. The Orange River is one of the main outfalls for Lehigh Acres, a highly channelized community in eastern Lee County. The channelization drained many wetlands, which increased both volume and rate discharging through the Orange River. Local residents and Lee County and SFWMD staff were very concerned about potential impacts the development could have on the existing flooding. Our team worked with the applicant, residents and permitting agencies to model numerous what if scenarios to identify a site plan that would get the applicant the number of units they needed while not impacting stages within the Orange River.
The number of wetlands systems throughout the project along with the relatively steep slopes necessitated a large number of lakes with a variety of control elevations. In all, 86 lakes with 22 different control elevations were required to maintain wetland systems while allowing appropriate flood control. This lead to an extensive on site modeling effort that included each lake as its own storage node.
Southwest Florida International Airport – Midfield Terminal
Southwest Florida International Airport’s Project Millennium is the largest Capital Improvement Projects (CIP) in the history of Southwest Florida, totaling over $380,000,000. The project included construction of the new Midfield Terminal Complex and associated facilities, the extension of Treeline Avenue from Daniels Parkway to Alico Road, the addition of a connector road from the Midfield Terminal to Treeline Avenue, expansion of parking facilities, and additional airport support facilities.
We began permitting of the project in the mid 1990s with a conceptual/surface water management permits which later facilitated a modification allowing for construction permitting the entire Millennium project. The conceptual approval saved several years of difficult permitting at the construction stage and allowed the airport to obtain the necessary land for mitigation prior to the actual construction permit receipt. All of the master drainage system, including the Fiddlestick Outfall to Ten Mile Canal, was designed by our surface water team.
Improvements continue today with removal of wildlife hazards to make the flying experience safer for the traveling public. Projects for this great need have to be woven through the challenging environmental permitting arena at the local, state, and federal levels. Our team is able to provide the analysis for maintaining the water management storage volumes as permitted, provide for continued expansion and improve passenger safety.
Gulf Coast Town Center
Our surface water team provided design and permitting assistance for this 1.6 million square foot out door center, which includes more than 150 specialty shops, restaurants and nationally known tenants. The design incorporated one large lake and two wetland pre-treatment areas for treatment and attenuation of the site’s runoff. This design created some unique challenges that were able to be over come by working closely with the client and review agencies. The location of the one large lake on the western most side of the site created very long and large pipe runs. Our team worked with the client to come up with the most cost effective design. On smaller projects the fewer number of pipes the cheaper the construction. On this site it didn’t work out that way due to the large pipes involved. The final design incorporated many parallel pipe runs into the pre-treatment areas to keep pipe sizes down and save money. Our surface water team also worked with the client to add fill on the eastern end of the site to further reduce pipe sizes and ultimately reduce construction costs.
LaPlaya Golf Course
Our surface water team provided design and permitting services for the redesign of the Palm River Golf Course. The Palm River Golf course and adjacent residential developments were constructed prior to current water treatment and attenuation requirements. In many locations the adjacent property drained onto the golf course without any treatment or attenuation. The neighborhoods around the golf course also experience significant flooding during portions of even a typical wet season. This design was further complicated by the review agencies that required the golf course to provide treatment and attenuation where it hadn’t been provided previously.
Our surface water team worked with the client, neighbors and review agencies to come up with a design that provided treatment and attenuation of the sites runoff while also reducing some of the flooding in adjacent neighborhoods where practical.
Florida Gulf Coast University
We provided design, permitting and construction inspection services on a variety of projects at Florida Gulf Coast University. Our surface water team provided surface water management design of permitting for each of these projects. Some of the projects include; Lutgert Hall, Holmes Hall, Alico Arena, Sugden Resort and Hospitality, Student Union, Parking Garage No. 1, Parking Garage No. 2, Student Services Building, Academic Building 7 and Several Student Housing Phases.
Charlotte County Surface Water Master Plan Phase II
We provided a dynamic modeling of a large portion of the Port Charlotte canal system that was not completed in Phase I. The modeling included inflow from the canal system in Sarasota County. The main issue was to look for opportunities on the sizing of weirs and culverts to reduce flooding and roadway overtopping. The roadway overtopping that occurred in 1995 had caused utility lines to be exposed and damaged along with partial roadway failures. The southern part of the county was modeled using as static model. This allowed more streams to be analyzed with lower unit cost. The permitting for the reconstruction of about a dozen water control structures was also a part of the work product.
