Why a flooding report does two jobs
Campaign position, not an agency finding.
Hydrology, pond fill, and treated-effluent overflow are in the withdrawn 889588 file. A resident flood photo is not proof the bank caused a past flood or will cause the next one.
What the official record establishes
These facts describe the regional system and agency review questions; they are not a project impact finding.
Lake Tarpon and Brooker Creek
SWFWMD’s 2025 Lake Tarpon SWIM Plan describes an approximately 37,000-acre watershed and identifies Brooker Creek as the lake’s main tributary. Pinellas County uses watershed-scale data and models for floodplain, drainage, natural-system, and water-quality work.
Documented high-water event
SWFWMD reported more than 6.5 inches of rainfall during Hurricane Debby on August 5, 2024, high flows from Brooker Creek, an overnight Lake Tarpon rise of more than 18 inches, and storm surge that limited discharge. This regional event does not establish conditions at a particular home or effects of the proposed bank.
Water quality
FDEP’s 2026 Integrated Report includes Lake Tarpon (WBID 1486A) among Clean Water Act section 314 impaired lakes and identifies biology, mercury in fish, and chlorophyll-a parameters. The County’s Lake Tarpon page discusses earlier monitoring results. Neither source proves a project-specific cause or remedy.

Course ponds and drainage
The current applicant filing describes ponds, restoration, and expected water-quality effects. Those are applicant proposals or predictions. The current RAI asks for more pond-restoration and water-related detail, so agency review remains incomplete.
The County and SWFWMD already studied this system
The 398-page Brooker Creek flood study, explained in plain English
This is not a neighborhood rumor, a campaign graphic, or an applicant’s sales presentation. Pinellas County and the Southwest Florida Water Management District funded a multi-year engineering study of the Brooker Creek watershed. URS Corporation Southern prepared the final report, dated May 25, 2010. The published PDF contains a 92-page main report plus hundreds of pages of model output, flood maps, cost calculations, and engineering concepts—398 pages in all.
The central lesson is straightforward: Tarpon Woods sits inside a large, flat, interconnected drainage system. Water entering or leaving the golf-course reach of Brooker Creek cannot be evaluated as though the property were an isolated 172-acre bowl. The report analyzed the creek, the Preserve, upstream watershed, neighborhood collection systems, roads, ditches, culverts, Lake Tarpon, and competing flood-control alternatives together.
Why we are publishing this now: The current mitigation-bank application proposes long-term changes within the same landscape examined by the study. The 2010 report does not decide the pending permit and does not model the applicant’s current design. It does prove that the agencies already possess a detailed watershed history, a model framework, and a documented warning that work through the golf-course reach can involve major hydraulic, environmental, permitting, and land-acquisition consequences.
How this study came to exist
Years of flooding complaints led to watershed-scale engineering
The report says street and yard flooding had been a problem in the Toniwoods portion of Tarpon Woods for many years. In response to a Pinellas County funding request, SWFWMD’s Pinellas-Anclote River Basin Board included money for the Brooker Creek Watershed Management Program in its fiscal-year 2004 and 2005 budgets. SWFWMD managed the larger project through work orders to URS, while the County’s environmental-management and public-works staff represented local interests.
Pinellas County Public Works separately hired Tampa Bay Engineering Group, commonly called TBE, to investigate possible solutions to Tarpon Woods flooding. TBE considered a flood-storage area and several ways to increase conveyance between Ridgemoor Boulevard and Tarpon Woods Boulevard. Its findings were presented to residents at a public meeting on September 27, 2007. URS and TBE then shared information, and one TBE concept—expanding the Brooker Creek channel through the golf-course reach—became Alternative 8 in the broader County/SWFWMD analysis.
This history matters because the current debate is not occurring on blank paper. County engineers, SWFWMD, consultants, the Tarpon Woods Action Committee, and residents were discussing the same creek reach and the same recurring flooding problem almost two decades ago.
Topography and field work
The program mapped watershed boundaries, storage areas, conveyances, flow paths, roads, ditches, culverts, and other features. The report says those features were checked through field reconnaissance rather than being inferred only from parcel lines.
Computer modeling
URS combined the Pinellas County model with an updated Hillsborough County model to simulate the entire watershed. The model compared existing conditions with proposed alternatives during 5-year, 25-year, and 100-year, 24-hour storm events.
Alternatives and costs
The study compared flood peaks, flood duration, wetland effects, environmental impacts, permitting difficulty, land needs, and estimated construction costs. It did not treat the cheapest excavation concept as automatically acceptable.
The scale residents need to understand
Brooker Creek is much larger than the proposed bank property
The study described a watershed of approximately 46 square miles, or 29,143 acres: about 10,737 acres in Pinellas County and 18,412 acres in Hillsborough County. More than 80 percent of the watershed’s soils were characterized as poorly drained with high runoff potential. Ground elevation falls from roughly 70 feet in the headwaters to about 3 feet at Lake Tarpon.
Water does not respect the property line
Rainfall and releases upstream can move toward the Preserve, through multiple historic and altered flow paths, across roads and utility corridors, into the Tarpon Woods reach, and eventually toward Lake Tarpon. A change that appears small on one parcel can alter timing, depth, direction, storage, or duration elsewhere.
That is why the current applicant should be required to place every proposed ditch treatment, planting area, access route, pond change, fence, structure, stockpile, soil-disposal area, and conservation boundary into a current, accepted watershed model.
Peak height is only part of the problem
The 2010 study repeatedly examined both the highest water level and how long the water remained high. A project can leave the modeled peak nearly unchanged while making drainage slower, keeping streets, yards, wetlands, or access routes inundated longer. Conversely, faster creek drawdown helps a neighborhood only if the local pipes, inlets, and outfalls can actually convey water to the creek.
The current review therefore needs hydrographs and duration results—not merely a statement that a finished contour will not increase a single modeled peak.
The option that directly involved the golf course
Alternative 8 proposed a major high-flow channel through Tarpon Woods
Tampa Bay Engineering’s carried-forward concept would have expanded approximately 3,400 feet of the Brooker Creek channel between Ridgemoor Boulevard and Tarpon Woods Boulevard to a width of 50 feet. The study’s 2009 cost estimate was approximately $7.1 million. The estimate included approximately 47,604 cubic yards of channel excavation, six acres of clearing and grubbing, 6.5 acres of wetland mitigation, a bypass pipe, seed and mulch, pedestrian bridges, engineering, survey, geotechnical work, and contingency.
What the model predicted
- Depending on storm and location, modeled stages in the Tarpon Woods area fell approximately 0.4 to 2.5 feet.
- During the modeled 5-year event, the report described the water level at one Tarpon Woods location as falling from 9.5 feet to 6.2 feet four days into the simulation.
- The alternative did not materially change flood duration in the Preserve.
- Faster creek drawdown would help streets and yards only if the neighborhood stormwater system had enough capacity to deliver water to the creek.
These are historical model results for a conceptual alternative, not predictions for the pending mitigation bank.
Why it was ranked low despite reducing flooding
The report said Alternative 8 reduced Tarpon Woods flood stages and duration more than any other alternative, but it gave the option a low implementation priority. The reasons were serious:
- wetlands along Brooker Creek would be excavated;
- the environmental impact was considered high;
- the project provided no hydrologic benefit to the Preserve;
- an Environmental Resource Permit would be required;
- land would have to be acquired through the golf course; and
- permitting and land acquisition were expected to be difficult.
Plain-English meaning: The study did not say “digging on the golf course solves everything.” It said a very large channel could reduce some modeled neighborhood flooding, but at the price of excavating wetland habitat, acquiring land, obtaining difficult permits, and addressing major environmental effects. That history makes vague assurances about ditch work, planting, “no earthwork,” or harmless hydrologic change unacceptable in the current proceeding.
What else the engineers considered
There was no single magic fix
The report evaluated thirteen preferred or combined alternatives. They ranged from relatively small culvert-and-weir projects to a long diversion channel, pumping stations, property acquisition, channel maintenance, power-line-road work, and the golf-course high-flow channel.
Higher-priority concepts
Alternatives 1 and 2—culverts, weirs, selected ditch filling, and restoration of historic flow paths on County-owned land—were ranked high. The study believed they could improve Preserve hydrology and reduce mainly the duration of Tarpon Woods flooding at relatively modest cost.
Enormous infrastructure concepts
Other concepts included an 8.6-mile diversion channel estimated at approximately $67.4 million, a pumped diversion to Lake Tarpon estimated at $15.9 million, and another pump-and-borrow-pit concept estimated at $30.9 million. High cost, limited effectiveness, and environmental or permitting difficulty lowered their rankings.
Maintenance was not enough
The report said channel maintenance between Ridgemoor and Tarpon Woods Boulevard might reduce water levels during more frequent rainfall, but it was not considered effective for reducing stages during the modeled 5-, 25-, and 100-year events. Removing obstructions may help ordinary drainage without solving major-storm flooding.
What this means for the pending mitigation bank
SWFWMD must reconcile the new proposal with the old model—not pretend the history does not exist
The 2010 study is not a permit denial by itself. It predates the present applicant, the present plans, newer rainfall records, current terrain, subsequent drainage work, FEMA map changes, and recent storms. Those limitations call for updated analysis; they do not justify ignoring the study.
Our opposition’s position is that no permit should be issued until the applicant and the reviewing agencies provide clear, written answers to the following questions:
- Use the accepted watershed model: What is the current official successor to the URS model, who maintains it, when was it last calibrated, and has the complete proposed mitigation-bank design been inserted into it?
- Show existing and proposed conditions: Where are the exact wetlands, ponds, floodway, ditches, berms, culverts, roads, historic flow paths, reclaimed-water inputs, planting holes, equipment routes, fences, monitoring facilities, excavation, fill, stockpiles, and disposal areas?
- Model both peak and duration: For ordinary storms and the 5-, 25-, and 100-year design events, how do water elevation, velocity, direction, storage, discharge, and time-to-drain change at every relevant neighborhood and Preserve location?
- Explain every difference from 2010: If the applicant’s analysis reaches a different conclusion, what changed in terrain, rainfall, structures, boundary conditions, roughness, tailwater, reclaimed-water operation, or model assumptions?
- Protect the regulatory floodway: Which activities overlap the effective FEMA floodway, and where is the signed-and-sealed no-rise/no-adverse-impact analysis and required County or FEMA review?
- Do not confuse restriction with improvement: Which acres already function as wetlands, flood storage, or conveyance? Existing function and already-restricted land must not be counted as newly produced ecological lift merely because it is placed inside a bank boundary.
- Resolve construction impacts: How much soil and below-ground biological material will be disturbed or displaced by more than 60,000 plantings, ditch work, access, maintenance, and monitoring? Where will that material go, and how will temporary or permanent elevation changes affect drainage?
- Test contamination before disturbance: Where golf-course chemicals or arsenic-based treatments may have been used, what sampling grid, depths, analytes, quality controls, disposal plan, transportation approvals, and certified cost estimates will govern disturbed soil?
- Guarantee long-term performance: What enforceable financial assurance, bond, escrow, adaptive-management trigger, repair obligation, and successor responsibility will protect the public if vegetation fails, structures clog, contamination is encountered, or hydrology differs from predictions?
Our demand: SWFWMD should deny the application unless and until the applicant supplies a complete, signed-and-sealed, independently reviewable hydrologic record demonstrating that every phase of construction, planting, operation, credit release, maintenance, and potential failure will not worsen flooding, damage the Preserve, obstruct the floodway, or shift risk onto surrounding residents. “We did not consider that outcome” is no longer an acceptable explanation. The agencies commissioned hundreds of pages of analysis precisely because this system is complicated and consequential.

A nearby permit-review lesson
If a pool required Brooker Creek modeling, the bank deserves at least that scrutiny
The record begins with a November 2024 contractor email, but it does not end there. Direct emails from County Engineer Dayne Morris and Division Manager Gene Crosson, a sealed letter from John C. Landon, P.E., and the November 2025 special-magistrate order document the determination, the engineering burden, the appeal, and the final affirmance of the pool-permit denial. The private emails and attachments are summarized and attributed below without publishing personal contact information.
What the review required
- The contractor relayed a County engineer’s explanation that verifying, modifying, or demonstrating no impact to the mapped floodway would require modeling and remodeling the broader Brooker Creek system, would be unusually costly for an individual owner, and would not guarantee approval.
- The contractor-relayed comments identified a floodplain base elevation of 12.10 feet NAVD; a later direct County email referenced 12.8 feet. That difference must not be silently harmonized. Each figure should be tied to its controlling map, model, cross section, datum, and review date. The earlier comments required proposed fill below the stated elevation to be offset by one-for-one compensatory storage, supported by existing- and proposed-grade surveys, fill calculations, and identified cut locations.
- The comments also called for a habitat inspection.
- A separate Florida Division of Emergency Management informational printout for the parcel reported Zone AE and “In Floodway: Yes,” while warning that the parcel intersects multiple zones and panels and that parcel-level results may not determine an individual structure’s status.
Evidence boundary: these records establish what was communicated during one neighboring permit review. They do not decide the mitigation-bank application or prove that every proposed bank activity lies in the floodway.
The public rules behind the concern
Pinellas County Code § 158-221 generally prohibits development in the 100-year and 25-year floodways, subject to stated exceptions. One exception can cover floodplain or habitat-restoration work only when ground-contour disturbance is minimal and the Code’s encroachment and compensatory-storage requirements are satisfied.
FEMA guidance explains that an encroachment in an adopted regulatory floodway requires hydrologic and hydraulic analysis demonstrating zero increase in base-flood levels. Pinellas County’s published floodplain-appeal procedure also describes a revised existing-conditions watershed model, applicant-funded review by a qualified independent professional engineer, iterative information requests, public notice in specified circumstances, County acceptance, and a FEMA map-revision process when the effective FIRM changes.
What Save Tarpon Woods is asking SWFWMD to require
Before any approval or credit release, require a signed-and-sealed, georeferenced overlay of the effective floodway, flood zones, cross sections, existing wetlands, every credit type, and every proposed ditch, plug, grading limit, planting area, access route, fence, structure, staging area, and conservation-easement boundary. Require project-scale hydraulic modeling, a no-rise/no-adverse-impact demonstration under the applicable standards, County floodplain-administrator review, compensatory-storage calculations where required, and any necessary FEMA map-revision approval. Existing floodway, wetland, and already-functioning habitat acreage must not be treated as newly created ecological lift merely because it lies inside the bank boundary.
Our standard is simple: residents should not face strict, watershed-scale proof for a backyard pool while a 172.46-acre commercial mitigation-bank proposal receives less precise floodway review.

What the floodway rule means in plain language
A floodplain and a regulatory floodway are related but not interchangeable. Zone AE identifies land subject to the one-percent-annual-chance flood where FEMA has established base-flood elevations. The regulatory floodway is the channel and adjoining land that must remain capable of carrying that base flood. Because an obstruction can push water higher or redirect it onto someone else, work in the floodway receives stricter review than work elsewhere in the mapped floodplain.
Pinellas County’s starting rule
Section 158-221 begins with a general prohibition on development in the 100-year floodway, the 25-year floodway, isolated wetlands, and designated preservation areas. The rule then lists limited exceptions. This means “restoration” is not a word that automatically removes a proposal from floodplain review.
A floodplain-maintenance or improvement project—including drainage work, bank stabilization, habitat restoration, or preserve work—may be considered by the floodplain administrator only when alteration of ground contours is minimal and the other required floodway and compensatory-storage standards are satisfied.
What counts as development
Floodplain regulation is broader than constructing a building. Filling, grading, excavation, dredging, drilling, paving, storage of materials, fences, access improvements, ditch modifications, structures, and other changes to the land can affect flood conveyance or storage. A proposal therefore cannot resolve the issue merely by saying there will be “no earthwork” if its plans still involve ditch work, planting holes, equipment travel, fencing, monitoring installations, vegetation removal, or displaced soil.
The no-rise principle
FEMA’s floodway guidance describes the federal minimum as zero increase in base-flood elevation from a proposed encroachment. That conclusion normally requires hydrologic and hydraulic analysis using accepted engineering practice, documentation of the effective model, an existing-conditions model, and a proposed-conditions model. A professional certification without the supporting model and assumptions would not let the public or reviewing agencies test the result.
Compensatory storage
Floodplain fill can displace water that previously spread or stored on the site. The pool-review comments required fill below the stated base-flood elevation to be balanced by an equal volume of excavation elsewhere on the property. The reviewer also requested existing and proposed grades, fill calculations, and the locations of compensatory cuts. For the bank, the equivalent analysis must account for every grading change, ditch treatment, planting displacement, access path, structure, fence, stockpile, and disposal location—not merely the finished contours shown in a conceptual narrative.
This explanation summarizes the County ordinance and FEMA guidance for public understanding. The current codified text, effective FEMA products, site-specific engineering, and decisions of the responsible agencies control.
What happened in the neighboring pool review
A small residential proposal triggered large-system questions
The files supplied by William Nobles document a proposed swimming-pool review at 172 Annwood Road. The first warning in the folder is a November 12, 2024 email from the pool contractor relaying County review comments. Later direct County emails, a sealed professional-engineer letter, and the November 2025 appeal order make the record substantially stronger. None of these documents rules on the mitigation bank; together they show how the County applied floodway requirements to a nearby project. Even with that limitation, it shows how seriously the mapped Brooker Creek floodway affected an ordinary residential permit.
- Mapped conflict: the contractor reported that the proposed improvement was shown in the floodway and could not be permitted as proposed.
- Not a simple survey correction: the contractor relayed the County engineer’s position that demonstrating no impact, verifying the line, or changing the mapped result would involve modeling and remodeling the entire Brooker Creek system—not simply submitting a spot elevation or moving a line on a site sketch.
- Cost and uncertainty: the relayed explanation said that work would ordinarily be beyond the practical reach of an individual owner and might not produce a favorable result.
- Elevation and volume: the comments identified 12.10 feet NAVD as the floodplain base elevation for that review and required one-for-one compensatory storage for fill above existing grade and below that elevation.
- Required documentation: the reviewer requested a survey of existing grades, proposed grades at improvement locations, calculated fill volume, calculated compensatory-storage volume, and the locations where the compensating excavation would occur.
- Ecological review: the comments also identified a habitat inspection.
Who said what
The Pool mailbox provides a documented chronology
The following is a redacted summary of floodway-relevant communications preserved in William Nobles’s iCloud “Pool” mailbox. Routine estimates, scheduling, signatures, and unrelated commercial messages are not part of this public-interest summary. Private email addresses, phone numbers, and signatures are not republished.
Initial permit issues
Hummel forwarded the review problem to the homeowners and reported that the improvement was shown in the floodway and could not be permitted as proposed. She relayed County Engineer Dayne Morris’s explanation that engineering could be used to verify, modify, or show no impact to the mapped floodway, but doing so would involve modeling and remodeling the entire Brooker Creek system, would generally be impractical for an individual owner, and would not guarantee a favorable result.
She also relayed requirements for existing and proposed grades, fill and compensatory-storage calculations, identified cut areas, and a habitat inspection. Because this message paraphrases or quotes a separate exchange, we treat it as contractor-relayed information—not the final word from the County.
Direct County determination
Morris wrote directly that the submitted survey confirmed the proposed pool was within the FEMA-designated floodway. He distinguished the earlier house permit from the proposed pool location and stated that, if the mapped floodway were wrong, the applicant would have to provide modeling to both Pinellas County and FEMA to demonstrate the error and change the maps. He concluded that the proposed pool location could not be permitted under Section 158-221.
This direct County email is stronger evidence than the earlier contractor summary because it identifies the County engineer, the specific proposal, the asserted mapped conflict, the modeling path, and the cited code section.
Survey overlay still showed an encroachment
Weigle wrote that the revised survey placed the pool deck on the drawing and that a triangular portion of the deck encroached into the floodway. He said that portion would need to be removed from the floodway and discussed moving the pool north to reduce—but not eliminate—the encroachment. This professional project correspondence did not overrule the County’s floodway determination.
County’s detailed written reasons
Crosson wrote that Engineering staff had reviewed the application and coordinated with the County Floodplain Administrator. He said the original plans, surveys, and supporting documents showed improvements crossing FEMA’s floodway delineation; modifying that line required FEMA’s Letter of Map Revision process.
Crosson also identified survey elevations below the 12.8-foot FEMA base-flood elevation within the construction footprint, missing grading information outside the deck, and an inadequate showing that the pool would cause no increase in design-flood elevation. He concluded that the proposal did not establish an erroneous map, did not demonstrate no rise under Florida Building Code R322.2.5.1, and could not be approved as designed.
Homeowner’s rebuttal
Nobles responded that a GeoPoint survey supplied new site-specific elevation information, that FEMA’s online overlay has a stated horizontal positional accuracy limitation, that the proposed deck was above the cited elevation, and that stem-wall construction would avoid grading or fill outside the deck. He asked the County to re-evaluate the permit using the surveyed elevations.
This is the homeowner’s advocacy position in the correspondence. It is important context, but it is not a County finding and was not accepted by the County in its subsequent response or appeal order.
County rejected the supplemental showing
Crosson replied that neither the written responses nor the supplemental documents adequately demonstrated that the project was outside the floodway or that it would cause no increase in flood stages. He said the Floodplain Administrator’s location determination was consistent with a third-party determination made during the 2013 single-family residence review.
He identified three available paths: move the construction out of the floodway, seek a FEMA floodway modification, or appeal the Chapter 158 determination.
Administrative escalation
O’Donnell acknowledged the homeowners’ complaints about the permit process, opened County Assignment Tracking System matter CATS 56351, and requested that County Administration have appropriate staff investigate and follow up. This shows escalation and receipt; it does not reverse the floodway determination.
Appeal procedure identified
Cord explained that the special magistrate retained by Pinellas County hears appeals alleging an error in a requirement, decision, or determination made by the Floodplain Administrator in administering Chapter 158. She directed the homeowners to Floodplain Management staff regarding the procedure.
Sealed engineering letter: small encroachment, large proof burden
Landon’s sealed letter said a corner of the proposed pool deck appeared to encroach into FEMA’s regulatory floodway. He described most of the deck as outside the floodway and above 12.8 feet, with a very small area below 12.8 that could encroach without mitigation. He considered the encroachment de minimis and said mitigation might be accomplished by lowering nearby sod areas.
Nevertheless, Landon wrote that federal and local law required a hydraulic analysis demonstrating no rise upstream or downstream. He said Pinellas County ordinarily required an exhaustive hydraulic analysis followed by peer review, at a cost probably greater than the pool project. His recommendation was to redesign the pool to avoid the floodway.
Appeal scheduling communications
Crosson told the homeowners he was coordinating with the section that schedules special-magistrate hearings, then later advised that an October 17 date had been cancelled and that he would provide the replacement date and process information. These messages document procedure, not the merits.
Appeal denied; County decision affirmed
After a November 10 hearing, Special Magistrate Fuller issued the written order in Case CCM-25-00086. The order states that the homeowners challenged the pool and deck denial, argued that FEMA’s 38-foot radial map accuracy and a professional survey supported a different site-specific result, and that the County defended the denial under Section 158-221.
The order found no reversible error, concluded that the Floodplain Administrator properly denied the permit, and affirmed the denial. It explained that land elevation was only one of the factors FEMA uses in determining the floodway and pointed to FEMA’s map-change procedure. This is the final decision located in the supplied mailbox; it is far stronger than describing the matter merely as an informal staff concern.
The opposition’s point: A homeowner supplied surveys, a rebuttal, and a sealed engineer’s letter describing a small encroachment. The County still required floodway avoidance or full hydraulic and FEMA process, and the special magistrate affirmed the denial. SWFWMD should not accept a lower evidentiary standard for a vastly larger commercial mitigation bank whose credits could authorize wetland impacts elsewhere.
The questions the application must answer
What residents should be able to see on one controlling plan
Separate surveys, narrative tables, conceptual plans, and viewer screenshots are not enough. The relationships must be shown together so acreage, overlap, disturbance, and credit claims can be checked.
Exact geography
- Effective FEMA floodway and Zone AE boundaries.
- County best-available flood data and controlling cross sections.
- Existing wetlands, surface waters, ponds, ditches, berms, culverts, and drainage connections.
- Every parcel, ownership boundary, proposed bank boundary, and conservation-easement boundary.
- Every restoration, enhancement, creation, preservation, buffer, and upland-support credit polygon with acreage.
Every proposed disturbance
- Ditch plugs, ditch filling, excavation, grading, pond work, and displaced material.
- Planting holes, root-ball dimensions, soil amendments, equipment routes, staging, and stockpiles.
- Tree removal, thinning, mowing, invasive-species treatment, fencing, signs, cameras, wells, monitoring stations, and utilities.
- Temporary and permanent access, maintenance routes, emergency access, and disposal areas.
- Existing and proposed elevations and stage-storage volumes for each affected basin.
Proof and enforceable answers
- Signed-and-sealed existing- and proposed-condition hydraulic models and assumptions.
- A documented no-rise/no-adverse-impact conclusion under the applicable standards.
- County floodplain-administrator review and written concurrence where required.
- Compensatory-storage calculations and permanent protection of the compensating volume.
- Any required FEMA conditional or final map revision before work dependent on a changed map proceeds.
- Permit conditions stopping work and credit release if field conditions differ from the approved model.
Credit boundary: Being located inside a floodway, wetland, or conservation boundary does not itself create ecological improvement. Credits should reflect only demonstrated, additional functional gain produced by the permitted work. Existing wetland function, existing flood conveyance, and restrictions that already protect the land must be identified so they are not presented as newly created value.
Unresolved hydrology questions
- What are the existing and proposed storage volumes and stage-storage relationships for each pond and wet area?
- How do ordinary and extreme storms move water through course ponds, Brooker Creek, roads, yards, and Lake Tarpon?
- What model, rainfall assumptions, tailwater conditions, control structures, and maintenance conditions are accepted by the reviewing agencies?
- How would the final grading, planting, structures, fencing, and long-term maintenance affect conveyance and emergency access?
- What reclaimed-water or effluent inputs currently enter the system, and how would operations change?
What a resident report can establish
A dated report can document water depth, duration, direction, affected areas, blocked drains, pond or creek conditions, and photographs at a particular time. It normally cannot establish watershed causation or predict a proposed project’s effects without a validated model and supporting measurements.
No reviewed primary source supports publishing an October 2024 project-specific high-water event as an established fact. Submit a dated source if one exists.
Also report it to Pinellas County
A Save Tarpon Woods submission goes to private community review. It is not an official County report, proof of notice, or guaranteed permanent record. For immediate danger, call 911.
County-report checklist
- Report active drainage issues through the County channel and keep the confirmation or case number.
- Record the date, time, duration, estimated depth, direction of flow, and broad location.
- Photograph safely from public property or your own property; do not enter floodwater or obstruct responders.
- Note blocked inlets, overtopping, pond or creek levels, road closures, and property effects without guessing at the cause.
- Keep originals private and redact faces, license plates, house numbers, and precise wildlife locations before any publication.
