Watershed Master Plan (City of Marco Island)
This is the work of the Center for Water Resiliency and Risk Reduction (cwr3) , Where I am a GRA.
Location of Marco Island, FL
Study Area
In the heart of Florida's West Everglades TMDL region, Marco Island sits poised at the gateway between the vibrant Gulf of Mexico and the vast freshwater expanse of the Big Cypress Preserve. This unique location makes it an ecologically critical area where freshwater and saltwater ecosystems intermingle. As part of Collier County, Marco Island shares its fate with the diverse landscape around it, including the nearby Everglades City. The area falls under the South Florida Water Management District (SFWMD) stewardship for water management and flood control. For this specific project, our focus zooms in on Marco Island's position within the Rooker Bay HUC 12 sub-basin, providing a detailed lens for our investigation.
Further Analysis of Result
The areas in blue are places that will likely experience flooding based on 1-Day 100-Year storm event. The areas in yellow are have the least chance of flooding.
What facilities are within the watershed
Priority was given to the following facilities
· Tier 1 - Critical facility protection (water/sewer utilities, public safety, hospitals, schools, power).
· Tier 2 - Essential facilities (groceries, pharmacies, roadways)
· Tier 3 - Economic centers (protecting jobs)
· Tier 4 - At-risk communities
To model the above question. The Department of Revenue (DOR) data was used. DOR Tier 1-4 facilities where 1 suggests higher priority was overlaid with parcel data for Marco Island, and this map was generate.
What facilities will flood at a given scenario
The Critical facilities data was put together with the 5ft sea level rise and 1-Day 100-Year storm event inundation map. The total area flooded for each facility was computed and a flood risk factor data was created based on the approved metrics.
How can vulnerable areas be mapped?
The Tier 1-4 dataset was revamp to the same scale as the flood risk factor dataset .
The two dataset were put together also based on approved metrics to give a final composite score map.
The facilities with the highest score are the most vulnerable if the predictions are to happen.
How is this information help stake holders?
Stake holders can now make data driven decision on how to solve the problem of flooding caused by storm events and sea level rise. Notable suggestions are ;
- practicing rainwater harvesting
- adopting pervious pavements
- building essential pump stations
- improving the strength and height of existing sea walls. etc.
Whats Next?
This is an ongoing project so any new outcome will be updated accordingly.
