CIVIL ENGINEERING / LAND SURVEYING / LANDSCAPE ARCHITECTURE

Nilles Associates, Inc. was established in 1996 in Ankeny, Iowa. We have grown from a small land surveying firm to a full-service civil engineering, land surveying and landscape architecture firm serving a wide range of private and public clients. We strive to make a positive difference to the clients and communities we serve, from the project planning stage through design, contract administration and construction.

Under the direction of John P. Nilles, PE & PLS, the company has become a leader in municipal engineering, land development, stormwater resources design, and master planning. We have provided innovative designs for projects large and small throughout the Des Moines metropolitan area and throughout the state of Iowa. As a smaller firm, we have stayed true to our roots, and continue to offer personalized survey and consultation services, no matter the size of the project.
