San Angelo-area acreage due diligence: jurisdiction, floodplain, septic and recorded-property research

For San Angelo-area acreage, check the actual parcel's jurisdiction, mapped flood risk, septic path and recorded property documents as separate questions. The City offers zoning, utility and river-corridor GIS layers but disclaims positional accuracy; City Engineering administers floodplain functions, while Tom Green County Environmental Health handles OSSF permits and mapped-floodplain review in its jurisdiction. The County's linked Lake Creek study is dated 2016, so ask whether it has been updated.

Start with a legal description and current survey. Ask the City or County to confirm who reviews the parcel and proposal, use FEMA's current map panel for screening, and obtain written floodplain, zoning and septic guidance from the responsible office. Review recorded easements and restrictions with the survey and title commitment. Neither a map nor a reservoir name establishes a parcel boundary, flood elevation, easement, legal access or development approval.

Facts to help plan the next check

• The Census Bureau reference point routes San Angelo to Tom Green County; a city centroid does not determine the county or jurisdiction of a particular parcel.
• The City of San Angelo Development Map offers zoning, water, sewer, river-corridor, transportation and address layers for initial research.
• The City says its GIS maps come from digital databases, are supplied as-is and carry no warranty for error, omissions or positional accuracy; verify parcel boundaries and decisions with the responsible office and survey records.
• San Angelo Engineering Services lists floodplain administration, stormwater management and subdivision-development review among its functions; ask the City whether its authority applies to the exact tract.
• The City publishes residential and non-residential floodplain development permit applications; the form is a starting point, not a determination that a permit is required or that a project will be approved.
• The City's zoning-verification letter does not confirm compliance with all development regulations or certify legal non-conforming status; request written confirmation for the parcel and proposed use.
• Tom Green County Environmental Health handles OSSF permits and inspections and reviews lot size and location for septic and floodplain issues; confirm which office has authority for the tract.
• Tom Green County says it regulates new development and substantial improvements in regulated, mapped floodplains and participates in the National Flood Insurance Program.
• The County Environmental Health page links a Lake Creek Flood Study dated 2016 and subdivision regulations amended in 2024; confirm whether later studies or amendments exist before relying on these materials.
• Tom Green County's real-estate records include deeds, deeds of trust, liens and other recorded instruments; a document search is not a title opinion or legal-access determination.
• The County links property-tax resources to Tom Green County Appraisal District; appraisal records support tax research but do not establish title, flood status, zoning or permitted use.
• The Texas Water Development Board identifies O.C. Fisher Lake near the northwest outskirts of San Angelo in Tom Green County; lake location and regional flood studies do not identify a tract's flood zone or easement boundary.

Parcel-specific next checks

1. Begin with the legal description, parcel account, current survey, deed and title commitment; do not use a city label, map pin or centroid as a boundary determination.
2. Confirm the tract's actual county and whether it lies inside San Angelo city limits, in an ETJ or in unincorporated county territory; ask the relevant City and County offices to identify their authority in writing.
3. Use the City Development Map to screen zoning, water, sewer and river-corridor layers, then ask the City for current parcel-specific zoning and development information.
4. If a zoning letter is needed, follow the City's current Zoning Verification Form process and ask about the exact proposed use; the letter has stated limits and is not a complete development-compliance review.
5. Search the FEMA Map Service Center by the property's address or coordinates and record the effective map panel and date; ask the local floodplain administrator about site-specific questions or newer studies.
6. For land in San Angelo, ask City Engineering whether floodplain review, drainage analysis or a development permit applies to the specific construction, fill, access or utility proposal.
7. For unincorporated property, contact Tom Green County Environmental Health about the mapped floodplain, any applicable Lake Creek study, current permit forms and the office responsible for a written determination.
8. Before assuming septic is feasible, request the County's current OSSF application and ask about site evaluation, soils, lot dimensions, system design and any subdivision review for the intended use.
9. Before dividing or replatting land, obtain the current County subdivision regulations and ask the County whether the tract and proposal trigger plat approval, infrastructure documents, fees or recording steps.
10. Search the County Clerk's recorded real-estate instruments and compare them with survey and title work for easements, access, restrictions and other interests; have a title professional or Texas real-estate attorney interpret them.
11. Ask the appraisal district about the parcel's account, valuation and tax history separately from title, zoning, OSSF, floodplain and permit questions.
12. Save dated map exports, written agency responses, survey/title records, OSSF materials and provider estimates in the Land Readiness Passport; revisit each item if the plan or source date changes.
