Temperatures outside may not make it feel like summer road construction season yet, but the season is upon us and signs of the work will start popping up in Brookfield very soon.

Preliminary work, including tree protection measures, tree removals and pavement saw cutting will begin as early as this week in some of the dozen or so areas targeted for street resurfacing or reconstruction.

By April 2, said Village Engineer Derek Treichel, repairs to sewer drainage structures will begin, beginning in earnest the third year of work funded through a $22 million bond issue approved by Brookfield voters in 2016.

Earlier this month, the Brookfield Village Board of Trustees awarded a roughly $4.4 million construction contract for the street improvements to West Chicago-based Triggi Construction, which submitted the lowest of 10 bids for the work.

Triggi’s bid was almost $900,000 (about 16.6 percent) below the village engineer’s estimate for the work, the third consecutive street bid to come in under the estimated budget.

“It’s the village’s decision,” said Treichel, “but with any leftover funds, the village would probably apply them to streets that were not part of the referendum [plan].”

The streets targeted for basic resurfacing this year include Cleveland Avenue, from Grand Boulevard to 31st Street; Lincoln Avenue, from Madison to Maple; and Riverside Avenue, from Arden to Hollywood.

Work there will also include removal and replacement of deteriorated sections of curb and gutter, the removal and replacement of some sidewalks and driveway aprons.

Windemere Avenue, from Vernon to Prairie, will be reconstructed, with complete curb and gutter replacement.

Streets that will be widened to 25 feet, in addition to being resurfaced and/or reconstructed with full curb replacement, will be Jackson Avenue, from Cleveland to Grand; Elm Avenue, from Brookfield Avenue to Fairview; Park Avenue, from Brookfield Avenue to Grand; Rosemear Avenue, from Brookfield Avenue to Washington; Parkview Avenue, from Arden to Rosemear; McCormick Avenue, from Southview to Riverside Avenue; Vernon Avenue, from Ogden to Burlington; and Elm Avenue, from Ogden to Shields.

In addition to those streets, which should be completed in mid-September, the village will also undertake two street projects funded in part by federal grants.

Elm Avenue, from Monroe to 31st Street will be reconstructed and widened to 25 feet, with full curb and gutter replacement. The work will cost an estimated $750,000 and is being funded in part by a federal $200,000 Community Development Block Grant. Referendum bond funds will pay for the remainder of that cost.

Also getting resurfaced in 2018 will be Custer Avenue from Ogden to 47th Street, a combined project with the village of Lyons. About 75 percent of that project is being funded by Surface Transportation Program funds through the Federal Highway Administration. The village’s share of the cost will be about $200,000.

The Illinois Department of Transportation is handling bids and construction contracts for both the Elm Avenue and Custer Avenue work, so those projects will begin and end a bit later than Brookfield’s referendum-funded work.

Finally, the bond-funded improvements this year will include repaving the main parking lot at Ehlert Park, on the west side of the park at Congress Park Avenue. The parking lot, which has not been resurfaced in more than two decades, will be excavated and completely reconstructed.

The parking lot work is scheduled to take place between July 5 and Aug. 15.

Also on March 12, the village board voted to award a $327,800 engineering services contract for the 2018 street improvements to Hancock Engineering Co.

The village is expected to issue a second round of bonds, in the vicinity of $6 million to $7 million to fund a portion of the 2018 work and work in the coming couple of years. Brookfield issued $9 million in bonds prior to the 2016 project.

The village is expected to issue the balance of what’s left of the amount approved by the referendum in 2020.
