To assist in creating a sustainable, environmentally friendly community, Tampa Bay Housing Authority opted to install a unique stormwater management-rainwater harvesting system and a solar panel array at their new Ultra-Green Inner-City Development known as “Encore Tampa” in Tampa, Fla. The elite stormwater management system, located under the new community park, controls and harvests stormwater runoff to irrigate the new green space park. The new $450 million venture is a 28-acre sustainable, mixed-use development that is designed to create an environmentally sensitive ecosystem, ultimately meeting the resident needs while preserving resources for future generations. 

Oldcastle Precast designed and provided the modular underground retention structure for the new stormwater management system, engineered by Clearwater, Fla.-based Cardno TBE, to store, treat, and harvest stormwater runoff on the site. The precast concrete Storm Capture retention system manages and controls the volume and discharge timing of stormwater runoff. The engineered design maximizes storage volume while minimizing the project’s footprint and cost. Furthermore, the innovative design allowed for a quick and efficient installation. 

The 18,000-square-foot, stormwater retention-harvesting system includes a Storm Capture vault composed of 146, 10-foot-tall Storm Capture modules that can hold up to 33,000 cubic feet of water before recycling it for irrigation use, two Nutrient Separating Baffle Boxes (Suntree Technologies) with adjacent sediment chambers for pretreatment, and a harvesting and irrigation equipment assembly (John Deere – Green Tech). All surface stormwater is collected from the site, piped into the Nutrient Separating Baffle Boxes and sediment chambers, and stored in the Storm Capture modules for irrigating the site landscape.

 

“I just don’t think anything can top the stormwater vault,” said Marc Marlano, assistant director of site development at Cardno TBE, in a YouTube video featured on the Encore site. “This is one of the most unique stormwater management systems in the state because of its size. It is 18,000 square feet of vault, which accommodates 33,000 cubic feet of stormwater. If they had used a conventional stormwater system they would have lost three developable sites. It is by far one of the slickest stormwater harvesting features in the state. There is no question about it. It’s just not done at this scale.” 

Oldcastle Precast also supplied precast perimeter walls for the sand filter assembly, precast ramp assembly for equipment access into the sand filter, sanitary manholes and inlets. Their sister company Oldcastle APG supplied 120,000 square feet of Belgard Hardscapes pavers and block for intricate hardscape paver walkways and permeable pavers for the center median of the main thoroughfare to reduce the heat island effect and aid in stormwater management.
