Incomplete: extraction pending for 2 of 23 governing permits (191235-3, 48694-7) — see Part 07. A production report does not finalise in this state.
Prepared 10 August 2026 · Source SJRWMD public ERP records, queried 2026-07-24
This report compiles and summarises public regulatory records. It is not engineering design, not a regulatory determination, and not sealed work. The permit file of record governs.
Part 01
Study area searched
The geometry this report was swept from — 150.0 acres, geodesic, as submitted. Same coordinates, same index: same sweep.
Teal: the boundary as queried. Grey: the 23 governing permits’ recorded footprints, clipped at the frame — one running off it is a permit far larger than this study area.
GeoJSON delivered in the source set; the fingerprint is the SHA-256 of its coordinates array.
Part 02
Executive summary
The study area contains 23 governing Environmental Resource Permits, carrying 544 documents across 7,421 pages. A further 18 permit records were returned and resolved as superseded — earlier sequences of permits that remain in the District index but no longer govern.
Extraction is complete for 21 of 23 governing permits: 525 regulatory criteria and 222 stormwater structures, each counted once. (68 duplicate extractions consolidated) 827 of 833 citations passed page-location verification — the quoted support was found on the cited page. 6failed and are quarantined in Part 09. Location is not interpretation; see Method.
Pending: extraction has not run for 191235-3, 48694-7 — inventory and index rows complete, registers and summaries not. Each card says so.
For 9 of the 23 governing permits, every retrieved document is from an earlier sequence of the file — labelled per entry, and read as file history (Method — Sequence lineage).
164 citations were read from deeper than any permit letter or staff report in this record runs — Part 04 sets out where.

Permit inventory & supersession
Every ERP record the SJRWMD index returned for this boundary (layer 2, queried 2026-07-24). Governing permits are listed first; superseded sequences follow, indented under the permit number they belong to. Completeness here means the index’s completeness as of that date — see Method for what the index does and does not cover.

Constraints found at depth
No permit letter or technical staff report in this study area runs past page 20. Those are the documents a file search reads. 164 of the 833 citations in this report were read from a page deeper than that — inside calculation books, bound submittals and as-built sets running to 450 pages — and 91 of those carry binding regulatory criteria.
Depth is not importance. A long document is not automatically a significant one, and a number on page 3 of a permit can bind a site harder than anything in an appendix. What this measures is where in the file the governing numbers sit — here, spread across 17 documents, past the page a reader of the permit and the staff report stops turning. A further 3 permits carry findings below the summary layer as well. Every finding counted here appears in the registers that follow, with its citation.

Permits and documents were retrieved from the St. Johns River Water Management District public ERP record, filter UPPER(RULE_TYPE_DESC) NOT LIKE '%CONSUMPTIVE%'. Only issued permits are reported.
Study-area geometry
The boundary in Part 01 is the geometry actually queried — fingerprint SHA-256 ef7112e961c7b315… over its GeoJSON coordinates, serialised without whitespace. Re-submitting the same coordinates against the same index layer reproduces this sweep. The intersection test is the district service’s own spatial query against its published permit geometry; that geometry is the district’s record of the permit’s extent, not a cadastral survey.
Supersession
Permit records are grouped by official permit number and ordered by sequence. The highest sequence is reported as governing; earlier sequences are listed as superseded. Supersession orders the record — it does not by itself resolve which conditions of an earlier sequence were carried forward, modified, or extinguished; where that distinction matters, read the governing sequence’s own authorization at the cited source.
Sequence lineage
The district’s document listing returns a permit’s complete file — every sequence, not only the governing one. Filenames carry their sequence of origin; every extracted entry in this report is attributed to its source sequence and labelled when it belongs to an earlier one. Where a governing sequence has no retrieved documents of its own, the report says so on the card rather than presenting older material as current. A filename that states no sequence is reported as unattributed, never guessed.
Document classification
Documents are sorted into engineer priority categories using the District’s own document typing and the document title, falling back to first-page text where the typing is ambiguous.
Depth measurement
The depth threshold in Part 03 is not a fixed number. It is the page count of the longest permit letter or technical staff report in this study area — 20 pages — so a citation past it is past the end of every summary document in the record. Depth is measured from the citation page recorded at extraction, against the page count of the retrieved file.
Citation verification (page-location)
Every extracted value carries the document and page it was read from, and is checked in two tiers. Tier 1 matches the supporting quotation against the text of that page: verified means the quotation was located on the cited page. Where tier 1 fails — nearly always a scanned or handwritten page with no reliable text layer — tier 2 renders the page as an image and verifies the value visually: page image means the fact was confirmed on the page image; needs review means the page does not support the value. unchecked marks a value not yet checked at tier 2 — read it at the source before relying on it. What this metric is: page-location verification establishes that the supporting text or value exists where the citation says it does. It is a check on citation integrity, not a review of the engineering interpretation built on it — a value can sit verified on its page and still be read wrongly in context. That review is what the cited sources, delivered with this report, are for. Values that FAIL the page-image check are quarantined in Part 09 rather than rendered beside relied-upon findings.
Vertical datum
Elevations are reported exactly as stated in their source documents. Of 82 elevation-class values in this report, 2 state a vertical datum on the cited page; the rest do not, and none is assumed — Central Florida ERP records of this era may reference either NGVD29 or NAVD88, and the difference is roughly a foot. Where a datum matters to a design decision, confirm it at the cited source.
Expiration dates
The “Expires” date on a permit card is the construction-authorization term as recorded by the district. Operation-and-maintenance obligations under an environmental resource permit generally continue beyond the construction term, so an expired date does not read as “no longer governs” — the governing label reflects the district’s current-sequence record as of the query date, and cards whose construction term has passed say so.
Coverage limits
Documents above the retrieval size limit are indexed but not read inline; they are listed in Part 08 and delivered with the source set. Construction plan sets are indexed, not parsed.
Standing
This is a research deliverable. It does not constitute engineering design or a regulatory determination, and it is not sealed. Where a value matters to a design decision, read it at the source document cited.
Remedy
If a governing permit inside this study area is missing from this report, tell us which one and the study area is refunded in full and re-run at no charge. Every value here is cited to its document and page so that claim can be checked rather than trusted.
