The site design minimizes land disturbance. Existing native trees, shrubs and beach grasses absorb rainfall and allow periodic flooding from coastal storm events to spread and recede naturally. Essentially, the entire site was returned to its natural condition. Hardscape pedestrian areas are composed of permeable pavers and gravel types, as adjacent rain gardens and bio- swales treating runoff. Native plantings allow water filtration and treatment within the rain gardens while reducing runoff volume and meeting pollution- reduction goals. A Resilient Landscape Given the great importance of sea level rise resiliency to CBF, the team worked to Above: WPL designed wooden railed walkways to match the height of the first floor of the building, raised 13.8 feet above sea level. At their full height, the walkways are unaffected in tidal ranges up to 7' above sea level. 40 Landscape Architect and Specifier News find the best building location on site and to set a floor elevation appropriate for accessibility and future storm and tidal surges. Winston Place, the main entry road to the Center, is the first permeable-paver public right- of-way in the city. It has no basins, inlets or pipes. Rainwater infiltrates through the pavers and into sandy soils. When a storm event provides excessive run-off, water flows into bio- swales flanking the street, ultimately improving water quality. The rain gardens are planted with Juncus grass, a native wetland rush, as well as Live oak, American Beach grass and Common rush. The rest of the site was left to naturalize. Since installation, other native wetland plants have taken root, creating a thriving rain garden system.
