WGI performed a topographic survey to support a Planning Assistance to the States (PAS) project, located in the Hollywood Lakes neighborhood along the Intracoastal Waterway in Broward County. Topographic data points and hydrographic soundings were obtained along eight miles of seawalls and grass berms and several detailed areas utilizing RTK GPS from a vessel. Data was used to model existing conditions that relate to increasingly frequent flooding of local streets, particularly during extreme high tide events, and facilitate alternative plans to reduce floodings, such as installing or raising seawalls or raising waterfront elevation streets or land. Deliverables included a Surveyor’s Quality Control report, GIS shapefiles, and a 3D ESRI GIS database with attribute fields containing observation locations, seawall material, width, adjacent bottom elevations, and photos of acquisition locations.
