Florida land due-diligence center
Start with the parcel location, then connect wetlands, flood, elevation, water, septic, access and official county records. Landeia keeps public screening separate from the survey, field work and agency decisions that actually control the project.
Choose the problem
You do not need to learn Landeia’s categories first. Start with the question that can change the deal.
Combine Census, NWI, FEMA and USGS point-level screening in one first pass.
WetlandsCould wetlands affect the buildable footprint?Move from map evidence to field delineation, agency process and project impact.
Water & septicWhat records exist—and what must be tested again?Find statewide/local record routes and identify the correct water-management authority.
Parcel recordsWhere is the official property appraiser/GIS record?Start with the Florida DOR county directory, then move to deed, plat, title and survey evidence.
Flood & elevationWhat does the FEMA map show—and what does elevation add?Document the effective flood map and use terrain data without confusing it with surveyed elevation.
Project areaHow much acreage remains after known constraints?Build a transparent area budget with an explicit overlap adjustment.
Site budgetWhat will the parcel need before the house?Build a Florida site-work budget from local quotes for access, clearing, water, wastewater, utilities, drainage and permits.
Before closingWhich Florida evidence is still missing?Work through parcel records, title/access, zoning, wetlands, flood, septic/well, utilities, cost and deadlines.

Parcel-wide thinking
Wetlands, flood, driveway access, septic/reserve area, well separation, easements, drainage and local setbacks can compete for the same few acres.
Compare consultant quotes by field, survey, reporting and agency scope—not a generic statewide price.
Understand PFO, PEM, PSS and other map classifications without confusing habitat coding with a regulatory boundary.
Separate historical records and nearby wells from new-site feasibility.
Combine survey, clearing, driveway, water, wastewater, electric, permits and contingency.
Florida source stack
Use federal mapping services together with Florida record directories and permitting routes. Each source states what it can—and cannot—prove.
U.S. Fish & Wildlife Service · United States
Query National Wetlands Inventory polygons and wetland codes for web-based screening applications.
Important: NWI is a screening dataset updated with the Wetlands Mapper and does not establish a regulatory boundary or jurisdiction.
U.S. Geological Survey · United States
Return a terrain elevation estimate from The National Map for a latitude/longitude point.
Important: The value is interpolated from elevation data and is not a surveyed elevation, benchmark or Elevation Certificate.
Florida Department of Environmental Protection · Florida
Screen drinking-water source and wastewater-treatment method for developed properties using statewide compiled data.
Important: DEP states that the inventory has data gaps and incomplete provider submissions; absence or classification must be confirmed locally.
Florida Department of Environmental Protection · Florida
Open recent onsite-sewage permit activity, Florida Water Management Inventory maps and county data downloads.
Important: Statewide datasets do not replace the local permit file, site evaluation or system approval for a proposed parcel.
Florida Department of Environmental Protection · Florida
Official rules and program information for water-well construction, repair and abandonment in Florida.
Important: Permitting is implemented through the appropriate water management district or delegated authority; a nearby well does not guarantee yield or quality.
Florida Department of Environmental Protection · Florida
Identify Florida's five water management districts and their regional responsibilities and websites.
Important: County boundaries can be split between districts and specific permitting responsibilities can be delegated.
Florida Department of Revenue · Florida
Find each county property appraiser, tax collector and value adjustment board official website.
Important: Property appraiser/GIS parcel lines and assessed values are administrative records, not a boundary survey or title opinion.
Florida Department of Environmental Protection · Florida
Open DEP Map Direct, the geospatial open-data portal and other official DEP mapping applications for program records and environmental context.
Important: DEP GIS layers and permit-location records are screening and record-retrieval tools; they do not by themselves establish a wetland boundary, jurisdiction, permit requirement or parcel buildability.
Florida Department of Environmental Protection · Florida
Identify DEP and water-management-district Environmental Resource Permit responsibilities and portals.
Important: The controlling agency and permit path depend on project type, location and operating agreements.
Florida Department of Environmental Protection · Florida
Official process for a legally binding determination of the landward extent of wetlands and other surface waters while the determination is valid.
Important: A formal determination is a separate agency process; a web map, desktop screen or consultant sketch is not the determination itself.
Federal Emergency Management Agency · United States
View, download and work with official effective flood-hazard data and map products.
Important: Flood-hazard layers do not replace a survey, elevation certificate, local floodplain review, insurance analysis or map-change research.
Federal Emergency Management Agency · United States
Official flood-map search and flood-hazard products.
Important: Flood maps do not replace insurance, survey, elevation, permitting or site-specific professional review.
U.S. Fish & Wildlife Service · United States
Mapped wetland and deepwater screening data.
Important: Mapped data does not establish regulatory jurisdiction or a parcel-specific wetland boundary.
USDA Natural Resources Conservation Service · United States
Official soil maps, properties and interpretations for an area of interest.
Important: Soil mapping is a planning resource and does not replace a site evaluation, perc test or engineering investigation.
Florida Department of Environmental Protection · Florida
Official context for Florida wetland evaluation, delineation and formal determinations.
Important: Map screening is not a formal or jurisdictional delineation and does not approve development.
