Our Services
Red Mountain Engineering (RME) provides specialized floodplain and floodway engineering services to support development projects requiring FEMA compliance. Our core services include CLOMR and LOMR submittals, no-rise certifications, and HEC-RAS hydraulic modeling to evaluate project feasibility and meet local permitting requirements. We also offer stormwater design, dam breach modeling, and a range of hydrology and hydraulics (H&H) studies across the Southeast. With extensive experience in floodway analysis and Alabama-specific regulations, we deliver clear, reliable results and responsive support to help projects move forward efficiently.

(Conditional) Letters of Map Revision (CLOMRs & LOMRs)
Navigating a CLOMR or LOMR can be complex and time-sensitive. Our staff is the only firm that specializes in map revisions, and includes experience reviewing these on behalf of FEMA. We help simplify the process by evaluating feasibility early, developing the required hydraulic models, and preparing complete submittals to FEMA. Our goal is to identify the most efficient path forward and keep your project moving.

We provide no-rise certification services for projects within FEMA-designated floodways, demonstrating that proposed development will not increase base flood elevations. Our work includes review and modification of effective HEC-RAS models, evaluation of existing and proposed conditions, and preparation of signed and sealed certifications for submittal. We focus on delivering clear, defensible results that meet local and FEMA requirements while keeping projects moving forward. Read more here.

Floodplain Analysis
We evaluate site conditions within FEMA floodplains and floodways to determine project viability and identify the most practical path forward. Services include review of flood mapping, feasibility studies, and evaluation of stream crossings, including culvert and bridge sizing. We identify potential permitting requirements such as no-rise certification or CLOMR/LOMR and provide clear guidance early in the process to reduce risk, control costs, and avoid delays. Typical applications include subdivisions, commercial developments, roadway crossings, and other projects impacting floodplains or floodways.

Bridge Hydraulic & Scour Analysis
We provide hydraulic and scour analyses to support bridge design, replacement, and realignment projects in accordance with DOT and FHWA guidelines. Services include HEC-RAS modeling of existing and proposed conditions, evaluation of bridge openings and roadway overtopping, and detailed scour analysis to inform design and permitting. We work closely with design teams to optimize bridge sizing and alignment while maintaining hydraulic performance and regulatory compliance.
