Talk Through Your SituationSpecialized Services
FEMA Map Revisions
When the LOMR stalls or FEMA pushes back
Letters of Map Change (LOMC), including LOMAs and LOMRs. Navigate the FIRM revision process with expert guidance and technical documentation.
Hydraulic Modeling
When analysis must be technically defensible
Advanced HEC-RAS and HEC-HMS modeling for riverine and pluvial systems. Accurate flood risk assessment using industry-standard methodologies.
Regulatory Compliance
When requirements are unclear or a submittal has stalled
Expert interpretation of FEMA guidance, NFIP requirements, and local floodplain ordinances. Ensure your projects meet all regulatory standards.
Floodplain Analysis
When site-specific flood risk must be precisely characterized
Comprehensive floodplain delineation, Base Flood Elevation determination, and floodway analysis to support development and mitigation projects.
When to Bring Us In
FEMA or the reviewing authority has pushed back on a submittal
The hydraulic or floodplain situation is technically complex or unusual
A standard workflow is not getting to approval
The timeline is tight and documentation must hold up under review
The prime consultant needs specialist support without expanding their service line

Common Questions
When should we bring in BaseFlood Engineering?
When the project has FEMA complexity that exceeds your team's core expertise, when a submittal has stalled, or when you need technically defensible analysis on a tight timeline.
Do you work directly with developers, or only through engineering firms?
Both. We work directly with developers and property owners, and we also partner with engineering firms as a specialist subconsultant—white-label or credited.
Can you help after FEMA has already pushed back?
Yes—that is one of the most common reasons clients reach out. We review what was submitted, identify the technical gap, and develop a path forward.
