Techny Prairie Park And Fields

Understanding the budgetary concerns for future maintenance needs of the park, the design team incorporated a number of long-term, cost-saving elements–the greatest of which was the native restoration of the prairie, reducing the need for mowing, fertilizing and upkeep of turf. The prairie will need to be periodically burned to maintain the quality of the ecosystem, but that cost is lower compared to traditional maintenance costs of the same acreage of turf. The use of Trex lumber for the boardwalk system will minimize future maintenance labor costs, since it does not require staining and has a longer life span than a traditional wood deck. Rather than using natural turf for the soccer and lacrosse fields, which requires significant maintenance and chemical treatments that may be harmful to the environment, the park district incorporated synthetic-turf fields. While initial costs are significant, these require only periodic upkeep and will have a longer life span than turf. The restored ecosystems are sustainable, meaning they require little to no maintenance, and benefit the environment.

One of the most unique aspects of the project is the use of milled asphalt from local road re-surfacing projects for portions of the trail system. The park district worked with the village to have the village’s roadway contractor haul the milled asphalt from the road projects to the park site. From there, the park contractor sorted any large pieces of asphalt that were not ground down enough during the milling process. The milled asphalt was installed by the park contractor throughout the site as part of an 8-foot wide trail system. The milled asphalt was installed similar to crushed limestone trail systems with a 6-inch layer of smaller-sized millings as the base course, and a 2- to 3-inch layer of finer-sized millings as the top course.


Techny Prairie Park meets ADA guidelines for public spaces, the Illinois Accessibility Code and the American Society of Testing Materials guidelines. Specific ADA guidelines include:

· Grading measures to ensure the trail and boardwalk are fully accessible and barrier-free. All of the walkways have a maximum longitudinal gradient of 5 percent.

· All programmed areas are ADA-compliant and fully accessible.

· Accessible parking is incorporated into the site improvements.

Impact Of The Park On The Community

Since construction was completed in 2006, Techny Prairie Park and Fields has become a premiere destination park for Northbrook and surrounding communities. It provides an incredible number of active recreation opportunities, and local neighborhoods utilize the trail system for passive recreation throughout the year–biking, jogging and walking. The trail connects to the much larger regional trail system of the Techny Trail, and its path through several ecosystems provides visitors with a variety of experiences, allowing them to positively interact with the natural environment.

The educational component of the Techny Prairie Park and Fields makes it truly unique to the community. Various programming events have taken place through the park district, as well as use by local schools and Boy Scout and Girl Scout troops. Visitors, young and old, are provided with a historical perspective on various approaches to living with the land. The boardwalk system traverses the wetland, allowing visitors to get “up-close and personal” with the plants, animals and insects that live there.

Techny Prairie Park and Fields is a noteworthy example of creating a community facility that provides both recreational and education opportunities. From building a wigwam, enjoying a quick round of golf or testing a new move at the skate park, to bird watching in the prairie–Northbrook residents have been given an incredible facility to enjoy and experience.
