Synergy performed design over a linear mile of boardwalks through environmentally protected marshes and wetlands in order to interconnect the neighborhoods with the natural environment of the Tolomato River and Stokes Creek. The design included stake out survey in order to avoid removing trees that would need to be replaced per county tree ordinance. A topographic survey was also performed in order to control the boardwalk deck elevations in order to be in compliance with Department of Environmental Protection regulations, Americans with Disabilities Act ramp limitations, and building code handrail requirements. The boardwalks were not only designed to handle pedestrian and golf cart traffic but also for transporting construction materials to otherwise inaccessible areas of the site, including Georgia Buggies loaded with concrete. J&D Marine is constructing the project for a cost of $2,000,000. Work began in March 2006 and is scheduled to be completed by the end of the year.

Synergy performed structural modifications for a dozen lift stations which were located below flood elevation as part of Hillsborough County’s hurricane preparedness improvements. Lift station modifications were prescribed by the project civil engineer, Jones Edmunds & Associates which included raising finished grade of some of these sites by as much as six feet. The structural scope performed by Synergy included design of services pads, pipe supports, extensions of existing wet wells and valve vaults, aluminum service platforms and handrails, man way hatches, access roadways, highway guardrails, and perimeter wood fencing.

Synergy designed steel bulkheads in order to maximize onsite retention of storm water runoff at several retail sites with limited available property.  The bulkheads were designed to support construction and heavy truck surcharge loads. Cantilevered steel sheet piling was used at the pond boundaries adjacent to the property lines, however the walls at the remaining perimeter were restrained with helical anchors for economy. Additional cost saving design included adding a drainage system behind the bulkhead in order to reduce hydrostatic pressure and subsequently reducing the pile lengths and anchor quantities. This work was performed for Kangaroo via subcontract to the civil engineer for the project, Kimley-Horn.

Structural deign included hardscape structures such as trellises, fountains, planters and monumental stairways. Retaining wall design included detailing of caps, corners railing, and tie-in with the building foundation retaining walls. All work was performed under the  direction of  the landscape architect, Prosser Hallock. The project was completed in 2004 at a cost of $1,400,000 by the general contractor, W.G Pitts.
