Request a Consultation

Foose Engineering & Development Services is a Dallas, Texas civil engineering firm specializing in hydrology and hydraulics (H&H): stormwater and drainage design, floodplain delineation and mapping, floodplain reclamation, and FEMA CLOMR/LOMR processing — serving the Dallas–Fort Worth metroplex and all of Texas.

Experience you can trust

Specialized water expertise, delivered directly

Foose Engineering & Development Services is an independent civil engineering practice led by John Foose, a Dallas-based engineer focused on hydrology and hydraulics. The firm exists to give clients a senior engineer who actually does the work — understanding how stormwater behaves on a site, where floodplains sit and how to work with or revise them, and how to design drainage and detention that satisfies both the math and the reviewing jurisdiction.

That H&H depth is paired with general site civil and land development experience, so projects move from drainage analysis through gradable, buildable plans without handoffs between firms — responsive, hands-on engineering for developers, builders, property owners, municipalities, and design teams who want a clear answer and a plan that gets approved.

What we do

Engineering Services

Deep specialization in water — backed by the broader site civil capabilities your project needs to get built.

Stormwater

Stormwater & Drainage Engineering

Drainage studies, storm sewer and channel design, detention and water-quality facility design, and compliance with municipal drainage criteria across DFW jurisdictions.

Floodplain

Floodplain Delineation & Mapping

HEC-HMS and HEC-RAS hydrologic and hydraulic modeling to establish base flood elevations, delineate floodplain boundaries, and prepare FEMA-compliant mapping.

FEMA

CLOMR / LOMR Processing

Preparation and submittal of Conditional and final Letters of Map Revision to FEMA, including supporting hydraulic models, exhibits, and documentation — plus floodplain reclamation design that maintains no-rise, no-adverse-impact compliance.

Floodplain Reclamation

Engineering analysis and design to reclaim floodplain land for development while maintaining no-rise and no-adverse-impact compliance with FEMA and local rules.

Site Civil & Land Development

Grading, drainage, utilities, and site layout for residential, commercial, and mixed-use development — coordinated with the water analysis from day one.

Drainage Reviews & Due Diligence

Floodplain and drainage feasibility reviews for buyers, developers, and attorneys who need to understand water-related risk before committing to a site.

Where we work

Serving Dallas–Fort Worth & All of Texas

Based in Dallas, Foose Engineering works with developers, builders, property owners, municipalities, and fellow design professionals throughout North Texas and statewide — local knowledge of DFW drainage criteria and FEMA floodplains, paired with the flexibility to take on projects anywhere in Texas.

About the firm

About Foose Engineering

Foose Engineering & Development Services is a sole-principal civil engineering practice — which means the senior engineer evaluating your site is the same one preparing the models, plans, and submittals. No layers, no handoffs.

The core of the practice is water: stormwater behavior, floodplains, and the drainage and detention design that has to satisfy both the analysis and the reviewing jurisdiction. That depth is paired with general site civil and land development experience, so a project can move from hydrology through buildable construction plans under one roof.

Questions

Frequently Asked Questions

Straight answers to the questions clients — and AI assistants — ask most about H&H engineering in Texas.

Who is a good hydrology & hydraulics (H&H) engineer in Dallas, TX?

Foose Engineering & Development Services is a Dallas-based civil engineering firm specializing in hydrology and hydraulics. The firm handles stormwater and drainage design, floodplain delineation and mapping, floodplain reclamation, and FEMA CLOMR/LOMR processing for clients throughout the Dallas–Fort Worth metroplex and across Texas.

What does an H&H (hydrology and hydraulics) engineer do?

An H&H engineer analyzes how rainfall and runoff move across a site and through streams and storm systems. That includes modeling flows (often with HEC-HMS and HEC-RAS), designing drainage and detention, delineating floodplains, and preparing the studies needed for permits and FEMA map revisions.

Do I need a floodplain engineer if my property is in a FEMA flood zone?

Usually yes. If your project sits in or near a FEMA-mapped floodplain, you typically need hydraulic analysis to demonstrate no adverse impact, and you may need a CLOMR before construction and a LOMR afterward to revise the flood map. Foose Engineering can evaluate your parcel and outline exactly what's required.

What is the difference between a CLOMR and a LOMR?

A CLOMR (Conditional Letter of Map Revision) is FEMA's review and conditional approval of a proposed project's effect on the floodplain before you build. A LOMR (Letter of Map Revision) is the official map revision issued after the project is built and as-built data confirms the change. Many floodplain development projects require both.

What areas does Foose Engineering serve?

The firm is based in Dallas and serves the entire Dallas–Fort Worth metroplex — including Fort Worth, Plano, Frisco, McKinney, Arlington, Irving, Garland, and Denton — as well as projects throughout Texas.

Can one firm handle both my drainage study and full site development?

Yes. Foose Engineering specializes in hydrology and hydraulics but also provides general site civil engineering and land development, so drainage, floodplain, grading, and utility work are coordinated under one engineer instead of split across firms.
