Maps: official sources and boundary limits

Use these agency viewers to examine parcel, land-use, flood, watershed, preserve, and applicant-proposed geography without treating an advocacy graphic as a survey.

Boundary notice: None of the summaries below is a legal description, title opinion, survey, flood determination, final conservation easement, or final permit boundary. Do not measure or infer exact boundaries from a screen image.

Non-map orientation

The permit record concerns a proposed mitigation bank in the Tarpon Woods golf-course landscape in unincorporated Pinellas County. The area lies within the Lake Tarpon watershed; Brooker Creek is the lake’s main tributary. Brooker Creek Preserve is a separate County preserve in the broader watershed. Parcel lines, a proposed bank area, wetlands, flood zones, and an eventual conservation-easement footprint are different layers and should not be treated as interchangeable.

Text legend

Parcel
A property-record unit; not necessarily the permit or easement boundary.
Proposed bank area
An applicant-defined review area that may change before any decision.
Flood map
Regulatory or planning information; not a prediction of every flood.
Watershed
Land draining toward a water body; not a property boundary.
Preserve
County-managed conservation land; not evidence that adjacent private land is within the preserve.

1847, 1944, and 1970 map evidence

Michelle Hollidge’s August 26, 2026 public filing identified historic exhibits in SWFWMD’s older Tarpon Woods Drainage Improvements record. We confirmed the three exhibits at pages 65–67 of the official 2005 Application 57947 / ERP 30028.000 package.

1847 General Land Office township plat for Township 27 South, Range 16 East
1847 GLO township plat, reproduced at page 67 of the official SWFWMD drainage package.

Federal cadastral survey

Orientation: Tarpon Woods is associated with Section 34, Township 27 South, Range 16 East, along the bottom row of the plat.

Use: Compare the original symbols and field notes with the applicant’s claimed historic ecological baseline.

Limit: Cadastral plats were made to survey public lands. Their symbols are not a current wetland delineation or a modern habitat map.

The necessary overlay

The record now contains at least six distinct geographic concepts that must not be blurred together:

  • the 172.46-acre applicant-proposed bank area;
  • the surveyed parcels and legal descriptions;
  • existing wetlands and surface waters;
  • FEMA flood zones and the regulatory floodway;
  • historic features depicted in the 1847 plat, early aerials, and federal quadrangles; and
  • each proposed restoration, enhancement, creation, preservation, upland-credit, earthwork, planting, and conservation-easement area.

Our position is that SWFWMD should require one signed, sealed, georeferenced exhibit showing every layer, acreage, overlap, and exclusion. That is the only defensible way to test whether existing wetlands, floodway land, or already-functioning habitat are being mislabeled or over-credited.

Current regulatory layer

Brooker Creek regulatory floodway crosses the landscape

The FEMA National Flood Hazard Layer view captured August 28, 2026 shows the regulatory floodway as the red-and-green hatched corridor through the broader Tarpon Woods area. Zone AE extends beyond that corridor. Visible map annotations include panel 12103C0077G, effective September 3, 2003, and panel 12103C0079H, effective August 24, 2021.

What this image does—and does not—show

The hatching is not decoration: it identifies the regulatory floodway shown by FEMA’s layer. It makes floodway overlap a question that should be answered on the applicant’s signed-and-sealed plans, not left to inference from separate exhibits.

Campaign position: the mapped floodway should remain untouched unless the applicant proves through every applicable County, FEMA, and District process that each proposed activity is lawful and produces no adverse hydraulic effect.

Important limit: this screenshot is an orientation image, not a survey, property-specific determination, permit decision, or substitute for FEMA’s effective FIRM and Flood Insurance Study. Do not use the screen image to measure an acreage or locate a legal boundary.

Pinellas County enterprise GIS

Orientation: Search the Tarpon Woods golf-course area, then inspect parcel and property-appraiser layers in the official viewer.

Legend: County viewer symbology controls; consult its layer list and metadata.

Limit: Displayed parcel geometry is informational. Confirm ownership, legal descriptions, and current records with the responsible County offices.

County zoning and future-land-use data

Orientation: Review the relevant County layers separately from parcel ownership and the SWFWMD permit record.

Legend: Use the official layer definitions and effective dates.

Limit: A mapped designation alone does not establish legal title, a surveyed boundary, a permit approval, or the lawfulness of a separate future proposal.

Legend: FEMA zone and floodway definitions control.

Limit: Being inside or outside a mapped zone does not mean a place will or will not flood. Use an official determination for legal or insurance decisions.

Limit: An evacuation zone is not the same as a FEMA flood zone, and neither substitutes for project drainage modeling.
