Plan around wetlands before you design.

A practical wetland due-diligence sequence

1. Gather the project record. Bring parcel IDs, a current survey, title or easement information, earlier permits and environmental reports, and a concept plan. Include purchase, financing and design deadlines.
2. Screen the full site. Compare wetland inventory, soils, aerial imagery and terrain in the map. Record each source and date. Follow up on unmapped low areas and features extending beyond the parcel.
3. Verify boundaries in the field. Arrange a delineation before treating a desktop line as a design constraint. Ask which state or federal method and agency review your project needs. See DEP’s delineation guidance.
4. Compare complete alternatives. Overlay the field boundary with buildings, roads, utilities, stormwater facilities, temporary access and staging. Record how each alternative avoids or reduces impacts.
5. Define the permitting scope. Identify the responsible reviewers, exhibits, studies and coordination needs. Assign responsibilities between the environmental consultant, engineer and surveyor before setting the application schedule.

Look beyond the building pad

Planning example: moving a building out of a wetland does not resolve an access route that still crosses it. Review both together.

Which permitting pathway applies?

Florida’s Environmental Resource Permitting program is administered by DEP and the water management districts. The reviewer depends on the location and activity; local requirements may also apply. Start with DEP’s ERP coordination guidance and confirm the project’s pathway with the agency.

For federal questions, confirm jurisdiction and authorization requirements separately. The USACE Regulatory Request System accepts jurisdictional-determination and permit requests. A wetland boundary, permit and zoning approval answer different questions.

Where impacts remain, discuss avoidance, minimization and any mitigation requirements with the reviewer. Do not assume that mitigation makes a particular design approvable.

What to request from your project team

• A dated map showing the parcel, field observations and wetland boundary.
• Soil, vegetation and hydrology documentation with the methods used.
• A coordinated overlay of the boundary and complete project footprint.
• A clear record of agency correspondence, review status and unresolved questions.
• A scope identifying further surveys, permits, mitigation planning and schedule dependencies.

For listed-species screening, use the separate EA Data workbench. Wetland review alone does not resolve every environmental constraint.

Common developer questions

Can I rely on the online map before closing?

Use it to identify questions for due diligence. Verify important boundaries and agency issues before relying on a layout or development budget. The property wetlands guide explains map limitations.

How long will review take?

Build the schedule around your project’s scope, field access, complete application materials and agency feedback. Request a scoped timeline rather than assuming a universal review period.

What if there is earlier clearing or fill?

Collect the earlier permits and correspondence and review the affected area. Our wetland violations guide explains how to organize a potential compliance issue.
