As a recognized expert in surface water analysis and civil design, OEI has a high volume of hydraulic, hydrologic, and hydrodynamic projects. We were established as a water resources firm over three decades ago and we remain true to this core competency, continuously adding to our successes of solving thousands of water issues nationwide, with a significant focus in our background: North and North Central Texas.

Water Resource Management and Regulatory Agency Expertise

OEI’s clients seek us to analyze and design resolutions for floodplain, flooding, drainage, erosion control, dam and levee safety and rehabilitation, streambank and creekbank stabilization issues, regulatory permitting navigation proficiency, and more.  We provide full design, analysis, studies, modeling, and, as relevant, construction phase services of complex problems with expert knowledge and efficiency.

Since OEI has been resolving surface water issues for over 30 years, we have developed efficiencies in streamlining the permitting processes and developing relationships with and a reputation among regulatory agencies, deftly navigating and working within the parameters of the complex regulatory process. Various regulatory agency rules often compete – and conflict – with each other on the same property. Most local firms have not been working long enough or focused enough within this thorny specialized sector; so, they run into setbacks. Which means more costly, longer periods of regulatory approval. How do we know? Because we have dozens and dozens of clients who started working with other engineers or firms, before giving up and finding us.

We are honored to serve our clients on the municipal, federal, private development, institutional, and industrial sectors.  Our team of professional engineers (PE) and certified floodplain managers (CFM) embody OEI’s foundation built on: continuous improvement, competency, teamwork, ownership (of the project/project goal), and ethical behavior.

Over 1000 LOMCs Submitted

A Track Record of Success

Few firms, let alone small businesses, can say they have submitted more than 1000 requests for Letter of Map Change (LOMC – Letter of Map Revision, Letter of Map Amendment) to FEMA.  Not only have we prepared this stunning number, our success rate speaks for itself: OEI has never been denied nor have our requests on behalf of our clients ever been substantively modified.
