Brookfield Greenway Trail Connections on North Avenue or Crossing North Avenue

Brookfield’s Civic Center Trail is routed along North Avenue between Calhoun Road and Pilgrim Road. A connection from the Underwood Creek Trail and the Elm Grove Trail is provided on North Avenue between Mound Zion Woods Court and Lilly Road. Other Brookfield and Elm Grove trails that connect to North Avenue are located on Calhoun Road, Pilgrim Road and Lilly Road. These trails are typically sidewalk/bike paths and/or on-street bike lanes. Other segments of North Avenue have no sidewalk or on-street bike lanes.

As part of the North Avenue reconstruction project paved bike paths/sidewalk will be provided on both sides of North Avenue between 124th Street and Calhoun Road. The sidewalk/bike paths will be 8-feet-wide between Calhoun and Pilgrim Roads and between Mound Zion Woods Court and Lilly Road. They will be 6-feet-wide in other segments. An extra-wide 14-foot lane on North Avenue will provide on-street bike accommodation on North Avenue (lanes are typically 11 feet wide).

North Avenue Noise Study Completed

Waukesha County and its consultant CH2M have completed a noise study for the project.  Noise is one of many impacts that are assessed as part of every study project following the National and Wisconsin Environmental Policy Acts.  The noise study completed for North Avenue uses a Federal Highway Administration-approved and tested software modeling program.  As part of that process, the team identified a number of representative receptors (typically homes and businesses) to portray existing noise levels and predict future noise levels based on the roadway’s configuration and the resulting proximity of traffic to adjacent dwellings and office buildings.  The methodology includes field measurements at a subset of receptors, computer modeling to verify that field measurements are consistent with the model’s predictions of existing noise, and then additional modeling using future-year traffic volumes and any changes in the location of the noise source(s) with respect to each receptor.  Future noise levels are then compared to existing to determine if an “impact” has occurred, and if so, if any mitigation options (noise walls, for example) would be both effective in reducing those impacts, and cost-effective based on the number of benefitting receptors.  The report includes all such findings.

Construction Now Planned for 2020

Waukesha County received additional state and federal funding to reconstruct the western one mile of the project at the same time as the eastern 2 miles so the construction of the whole 3-mile segment from 124th Street to Calhoun Road will begin in 2020. Waukesha County is still evaluated whether construction can be completed in one year or will be spread across two years. Either way, North Avenue will remain open to traffic during construction except for a few weeks when the railroad crossings near North Avenue and Pilgrim Road intersections are replaced.

Environmental Assessment Nears Completion

The environmental assessment that documents the need for the project, the alternatives Waukesha County considered, and the impacts of the project is under review by the Wisconsin Department of Transportation. It will then be submitted to the Federal Highway Administration for review. It will be available for public review after WisDOT and the Federal Highway Administration approve it, later in 2018.

Third Public Involvement Meeting Held on Tuesday, November 15th, 2016

The project’s third Public Involvement Meeting was held at the City of Brookfield’s Safety Building on November 15th from 4:30pm to 6:30pm.  The meeting included new information on impacts to parks and historic sites which are protected under Section 4(f) and new information on a design change to avoid impact to Pioneer Cemetery on North Avenue near Pilgrim Road.  Section 4(f) is a federal law that stipulates that FHWA cannot approve the use of land from publicly owned parks, recreation areas, wildlife and waterfowl refuges or public and private historical sites unless there is no feasible or prudent avoidance alternative and the project includes all possible planning to minimize harm to the property resulting from such use; or FHWA determines the use of the property will have a de minimis impact.

The meeting was held in an open house format, and approximately 40 people attended.  Representatives from Waukesha County and their consultant team were present to answer questions and receive comments.  Please click on the links below to see the project displays and other information provided at the meeting:

North Avenue Traffic Report Completed

Waukesha County and its study team has completed the traffic study and report for the project. The traffic report includes findings related to existing traffic and forecasted traffic growth over the next 20 years for the corridor and for intersections located between Calhoun Road and 124th Street. The appendices to the report provide more data and details with respect to the counts and forecasts, and analysis leading to the conclusions and recommendations included in the report. These recommendations have provided information used to develop various improvement alternatives along the 3-mile project corridor.

Second Public Involvement Meeting Held on Tuesday, March 15th, 2016

The meeting was held at the City of Brookfield’s Safety Building, and ran from 4pm to 7pm.  Over seventy attendees viewed project displays highlighting existing conditions and early conceptual design elements, and discussed the project corridor with representatives from Waukesha County and their consultant team.  Click on the links below to see the project displays and other information provided at the meeting.

Initial, Preliminary Range of Improvement Alternatives Under Development

Since the project’s inception last Summer, and based on feedback provided by residents, business owners, municipal officials and other stakeholders, the study team has been collecting data and investigating traffic, safety, and field information to develop a range of alternatives, including “do-nothing” and reconstruction alternatives including 3, 4, and 5 lane configurations.  Please click the links to view pdf pictures of preliminary 4-lane (with grass median between travel lanes) and 5-lane (with continuous two-way left-turn lane between the travel lanes) alternatives.  These two alternatives satisfy project purpose and need objectives, to handle future (Year 2039) forecasted traffic volumes safely and with acceptable levels of congestion.  Neither the “do-nothing” nor the 3-lane alternative passed the purpose and need test, and are no longer considered viable alternatives.

These remaining alternatives are subject to continued revision and refinement as the study continues through the rest of 2016.  Working with stakeholders, Waukesha County continues to study a number of design features, including:  lane, median and terrace widths;  sidewalk locations;  driveway and median opening locations;  intersection options (no signals, signals, and roundabouts in three locations), and any new right-of-way (land) that might need to be acquired to construct the alternative.  All information remains preliminary and subject to change.  Your continued participation is absolutely vital to the study process, as alternatives continue to be studied and refined.

North Avenue Reconstruction Project Context Sensitive Solutions Advisory Group

Waukesha County has established a Context Sensitive Solutions (CSS) Advisory Group for the North Avenue Reconstruction Project.  The CSS Advisory Group is made up of a wide range of stakeholders who have an interest in potential improvements to North Avenue between Calhoun Road and 124th Street.  Members of the Advisory Group include residents, businesses, and elected officials.

The CSS Advisory Group will meet 10 times over the course of the North Avenue Reconstruction Project to discuss project related issues ranging from issue identification to alternatives and finally detailed design.  The meetings will be held at the Brookfield Library between 4:00pm and 6:00pm on the dates listed below (please note that meeting dates are subject to change based on project progress).

Project Description

routeIn June 2015, the Waukesha County Department of Public Works (Waukesha County) began a detailed study of the North Avenue corridor between Calhoun Road and 124th Street at the Milwaukee County Line, a distance of approximately 3 miles. The corridor is a mix of two- and four-lane roadway, with turn lanes at selected intersections and a significant number of residential and business driveways located throughout the project’s length. Important abutting land uses include private homes, businesses and parking lots, parks, cemeteries, a major railroad crossing near the busy North Avenue/Pilgrim Parkway intersection, and wetlands associated with river and ditch crossings.

Please see the Study Area Map included here for some information regarding the project limits and features along both sides of North Avenue between Calhoun Road and 124th Street.

Project Process

Waukesha County will be completing a detailed study of a wide range of existing conditions, including:

  • Traffic volumes, growth and congestion
  • Safety performance, specifically reviewing crashes and crash types and frequencies
  • Pedestrian, bike, and other multi-modal use of the roadway
  • Potentially historic and archaeological elements of buildings and land uses along the corridor.

Waukesha County is now assessing a range of alternatives intended to address and improve noted deficiencies in operations and user safety. These alternatives range from fairly minimal (reconstruct the roadway as is), to safety improvements, to adding lanes along the route and at intersections. These alternatives will be shared extensively with users, residents, business owners, and others along the corridor and beyond.

Project Schedule

After the range of alternatives is developed and reviewed with stakeholders, they will be refined. It is expected that Waukesha County will selected a preferred alternative in mid-2016. Subject to agency and stakeholder acceptance, and to funding availability, Waukesha County anticipates preparing design plans for the selected alternative in 2017-2018, and initiating construction in 2019.

Waukesha County will coordinate extensively with the City of Brookfield, the Village of Elm Grove, the Wisconsin Department of Transportation, and a wide range of neighborhood, business, community service, and review agency stakeholders to develop a range of alternatives for reconstruction of North Avenue.

Next Steps

Waukesha County has developed a project mailing list (all those with property abutting North Avenue will be included in that list, and will receive regular project notices and updates). If you would like to be added to the mailing list via email or US mail, please fill out the form below.
