How Landeia results work

Research and Calculator Methodology

Landeia connects broad property research with land due diligence while keeping screening, assumptions, evidence and formal determinations separate.

1. Start with the buyer’s actual question

Research begins with practical property questions—where are the parcel lines, which FEMA flood map applies, what is the acreage, what might financing or site work cost—and then connects each answer to the evidence needed before a land decision.

A useful answer should help the buyer take the next step, not simply define a term.

2. Define the exact decision

Each page states the audience, what it answers and what it cannot determine. A page about a property-line map owns map-finding and interpretation intent; a boundary guide owns deed, plat, title and survey verification; a buildability checker owns preliminary project screening.

3. Preserve unknowns

An unanswered high-impact question is not treated as a positive result. It lowers confidence and remains in the next-step list. This is especially important for legal access, use, water, wastewater, flood, wetlands and physical constraints.

4. Use an evidence hierarchy

  • Public map or listing: identifies a question and record reference.
  • Official record or adopted document: supports the fact within its stated scope.
  • Written authority or provider response: connects the fact to the jurisdiction, service or project.
  • Qualified parcel-specific work: establishes field, technical or professional conclusions within the engagement scope.
  • Permit, title policy or formal decision: provides the controlling transaction or approval outcome where applicable.

5. Distinguish screening from determination

  • A GIS line can orient research; it does not establish a legal boundary.
  • A flood or wetland layer can show mapped conditions; it does not guarantee safety, jurisdiction or buildability.
  • A questionnaire can identify missing evidence; it does not approve a project.
  • A cost model can stress-test assumptions; it is not a contractor quote.
  • A comparable-sale range can organize evidence; it is not an appraisal.

6. Show calculator assumptions

Calculator fields start empty, with examples showing format rather than default claims. Users enter the price, rate, depth, area, local tax structure, system cost and site assumptions used in the result.

Worked examples are explicitly illustrative. They explain mechanics and risk sensitivity without being presented as national price benchmarks.

7. Prefer claim-level primary sources

Legal, regulatory, mapping and program claims should link to government or other primary sources. Source records identify the owner, geography, intended use, limitation and last-checked date.

Specialist guides add topic-relevant sources instead of relying only on a generic county-records link.

8. Give each page one clear job

Map pages help people find and interpret a public record. Calculators make assumptions visible. Interactive checkers organize parcel-wide questions. Specialist guides explain one legal, technical, financial or environmental issue in depth. State pages connect statewide systems to the county, city, district or parcel records that ultimately control the answer.

Related pages link to one another when the user’s next question genuinely changes, so visitors can move from screening to verification without reading duplicate explanations.

9. Review, update and correct

Publication, substantive modification and source-review dates are generated page by page. A modification date changes after meaningful content, evidence, functionality or limitation updates—not to create artificial freshness.

Material corrections should update the page, source record and machine-readable content index.
