Morris L. Preston started a branch office in Davenport, Iowa in 1991 after a nineteen year career with the Iowa DNR. He purchased the office in 1995 and changed the name to Preston Engineering, Inc. Mr. Preston is a professional engineer licensed in Illinois, Iowa and Nebraska. He is also a certified groundwater professional in Iowa.

Preston offers a broad range of environmental services typically mandated by state or federal law. Preston served as the principal contractor to the Iowa leaking underground storage tank program during which cleanup reports were reviewed at over 5,000 sites. Another highlight was assisting the City of Dubuque by performing dozens of site assessments in the Ice Harbor project that facilitated the construction of the Mississippi River Museum, the Water Park Hotel and Convention Center, and the redevelopment of the Star Brewery. Preston has been particularly active in the West Davenport Brownfields project. Preston has also helped industries such as cement plants and lime plants obtain construction permits, PSD permits and Title V permits. Numerous SPCC plans have been written to help oil storage facilities prevent and respond to oil releases.

Preston strives to maintain a qualified and professional staff to work on a wide variety of projects. We have relationships with numerous subcontractors to provide specialized services.
