Since it was founded in 2001, Affinis has collaborated with clients to move communities forward through roadway design. By carefully engineering thoroughfares, we help cities increase safety, support economic growth, and provide access for multiple modes of transportation. With stormwater, survey, and construction engineering services in-house, clients get a turnkey solution for their civil engineering projects.

For each effort, our talented team considers the entire site. Working within the budget, we evaluate a variety of approaches when repairing, reconstructing, or building a new thoroughfare. Not all projects require full survey and design, and our co-workers will work with you to find the right mix of solutions. Our personalized approach factors in future maintenance, a city’s standards, and disruption to residents and business owners.

Affinis accomplished our two, primary goals for the 159th Street project. The selected roadway design is the right size for the area’s projected growth, and they were able to successfully coordinate with Blue Valley High School, minimizing disruptions to the school.

City of Lee’s Summit Makes Ward Road Safer for All Users


The City of Lee’s Summit wanted to improve Ward Road, an arterial on the southwest side of the city, to increase the safety for all users. Pedestrian access was incomplete, and it didn’t easily accommodate cyclists alongside vehicles.


Roundabouts Improve Traffic Flow and Safety on 159th Street

Prior to our 159th Street improvements between Metcalf and Nall, Blue Valley High School had been experiencing traffic congestion on 159th Street for an extended period of time. Safely making left-hand turns out of the school’s entrances during peak hours was becoming increasingly difficult.


Transportation Engineering

Designing streets, thoroughfares, highways, and traffic projects is a balancing act at which our team excels. Skilled at gaining stakeholder support, we are able to strike an important balance of working with clients, the public, and utilities. Our ability to clearly communicate our designs and the rationale behind them has helped us create positive working relationships with city, county, and state agencies, as well as utilities.

Water Resources

Designing stormwater improvements is a collaborative effort. It begins with our internal team of experienced professionals and typically involves partnerships with clients, utilities, and residents. We continue to earn repeat work from many municipalities, because we are skilled at minimizing the impact of our designs and the need for future maintenance

Federal Services

Committed to excellence, our experienced team offers a full suite of civil engineering services. We have the ability to take civil engineering projects from start to finish. With just a few points of contact, our project communication is streamlined to make our federal clients’ lives easier.

Site Development

Considered a trusted partner by our clients, we understand the intricacies of properly developing a site. Whether we are working with an area that is partially developed or untouched, we have experience designing plans that maximize your land.

Survey & Field Services

Often the first face of a project, our team considers themselves to be an on-site representation of our clients. Having the right tools helps us collect data accurately and quickly. With the capability to exchange data and messages instantly between the field and office, we’re able to capitalize our time spent onsite. In addition to survey services we offer construction inspection with KDOT certified inspectors to offer quality control on-site.
