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
Project Need
Over 25 Years of Reports and Data
LAS Images Rasters
….
Geospatial Data + Documents
Where to Start
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
• 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
• Survey identify light issues that need to be corrected by the property owners.
Beach Lighting Surveys
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

Stats & Effort …
2000+ Hours
• 6 File Geodatabases (1 vector + 5 rasters)
• 200+ hydrographic surveys
• 22+ Feature Datasets (1 – 36 Feature Layers)
• 600+ Feature Layers
• 40 Tables +++
5 GB

How it is used
GIS is now Part of the Coastal Engineering Department Workflows
• Project Information Consolidation and Organization & Lookup
• Asset Management (i.e. Channel Markers)
• Project Management & New Project Planning
• Data Analysis
• Prepare Grant and Permit Applications
• Public and Stakeholders Sharing of Information
• Visual Aids for Meetings
• Brochures
