Since our earliest beginnings in 1935, Willett, Hofmann & Associates, Inc. has been creating civil site designs for residential and commercial sites for both private and public owners.  

Our staff provides engineering services for the design, permitting and construction of sites ranging from single lot commercial, industrial and governmental sites to multi-lot urban and rural residential subdivisions.  Included in these designs are stormwater management and detention, site grading, parking lot design, roadway design, entrance design, storm and sanitary sewer design, and water distribution for domestic use and fire protection.

Our engineers and technicians utilize the latest computer software along with their own vast experience, education and training to provide our clients with cost effective constructible plans resulting in a finished product that enhances the surrounding area.

We are experienced with state and local agencies with jurisdiction over developments and work with those agencies to ensure their standards and specifications are met in the design process.  We also provide construction layout and construction engineering to ensure the final product meets the design requirements and the client’s expectations.

Whether the project consists of increasing parking, improving drainage, or a change in land use on an existing site, or developing a completely new subdivision or facility, Willett, Hofmann & Associates will provide responsive services with qualified staff to bring your idea to reality.
