Presentation Overview County Coastal Programs Coastal GIS Project Data Consolidation and Organization Project Planning and Management Tools Data Analysis Tools Public Information Sharing Project Summary How it is Used St Lucie Inlet Planning Tool
Coastal Monitoring Program Aerial Photography Shoreline Hydrographic Surveys Sea Turtle Monitoring Monitoring Gages (i.e. wave gage)
Habitat Coastal Management Programs Overview Program Offshore Artificial Reefs Nearshore Mitigation Reefs Nearshore & Offshore Natural Reefs Indian River Lagoon Mitigation St. Lucie River Fishing Recreation Natural Reefs Habitat Enhancement St Lucie and Loxahatchee River Oyster Restoration Living Shorelines Water Quality and Land Sources of Pollution
Waterways Management Programs Stuart Smaller Dredging Projects (i.e. access channels) Okeechobee Waterway St. Lucie Inlet Atlantic Ocean ICWW and OWW (County is local sponsor managed by FIND) Intracoastal Waterway Mooring Areas and Fields (i.e. Manatee Pocket)
Inlet Management Program Inlet maintenance (channel, Stuart jetties, breakwaters) St. Lucie Inlet Atlantic Ocean St Lucie Inlet Federal Channel Maintenance (Local Sponsor) Sediment basin dredging and sand bypass to the south beaches
Beach Restoration Program Stuart Hutchinson Island Bathtub Beach Park Sailfish Point Two Long-term Beach Renourishment Projects (Federal: County and City of Jupiter Island) St. Lucie Inlet State Park Hobe Sound National Refuge Jupiter Island Atlantic Ocean Placements from Inlet and Waterway Dredging Projects (Regional and County) Smaller Projects when needed (County and Community)
Coastal GIS Program
Project Goals Facilitate the Management of Permit and Grant Monitoring Requirements and Compliance Consolidate Department Data and Create a GIS Program Facilitate Coastal Engineering Project Planning and Management
Where Project to Need Start Over 25 Years of Reports and Data LAS Images Rasters. Geospatial Data + Documents
Types of Spatial Coastal Data Project Specific Spatial Data Engineering Environmental Monitoring Surveys Topo and Bathymetric Natural Resources Sediment and Water Regulatory (Federal, State, County) Base Layers (Federal, State, County)
Consolidation & Organization Data type and format What programs use a specific dataset Does it need additional external information to complement the dataset What type of information does the County need Best way to consolidate in GIS
Hydrographic Surveys County Shoreline St Lucie Inlet and adjacent areas Navigation & Sediment Basin Beach restoration surveys Pre and Post Construction 1 to 3 Year post monitoring Borrow areas Waterway projects Artificial reefs County needs to access the original data, what areas were surveyed and when, compare surveys volume changes and where erosion, accretion, extract cross sections, and depth for different projects
Hydrographic Surveys XYZ LIDAR files Original XYZ GIS Geodatabases
Beach Lighting Surveys Beach Lighting Surveys are required monitoring for beach restoration permits Sea turtles when they hatch look for the moon to find the ocean Beach property lighting if seen from the beach may cause the hatchlings to get disoriented and go towards the lights instead of the ocean County needs to know what and where is the issue, if it is recurrent, if it was fixed, and there are any disorientation reported in the problem area Survey identify light issues that need to be corrected by the property owners.
