Brentwood public works updates roadwork schedule, flood and sinkhole responses
Summary
Public Works reported on Brentwood Boulevard signalization and widening, overnight paving for McKnight Road, a Lewis Avenue sinkhole under MSD review, and a Park Ridge basement flood from a recent storm; construction timelines run into fall.
Public Works staff updated the Brentwood Public Safety Committee on July 24 about several infrastructure and stormwater matters, including signal work at Brentwood Boulevard and a pair of localized storm-related property impacts.
Union Pacific has completed testing of new signals at Brentwood Boulevard; staff said the median still requires final adjustments and a 55-foot mast arm slated to arrive in early October should allow completion of the intersection signalization by late October or early November. Widening work on Brentwood Boulevard is scheduled to begin in August and continue into early September, with paving and final overlay to follow.
Crews will perform evening and overnight milling and paving on Beauver and McKnight roads; Public Works said the contractor will start milling at Litzinger and McKnight and complete asphalt placement the following morning, with message boards, flaggers and recommended detours to manage traffic. The contractor estimated 6'to'7 hours of paving work per segment and striping the following week.
Public Works also reported a sinkhole on Lewis Avenue thought to be related to a sewer lateral; staff contacted the Metropolitan St. Louis Sewer District and said they are awaiting dye-test results. Separately, a storm on the 16th caused roughly 5 feet of water to flood a basement at a Park Ridge home, damaging mechanical systems; staff said MSD will meet on-site with the homeowner and city staff to investigate an inlet/easement near Ameren poles that appears to have driven the pooling.
Public Works said the Brentwood Park overflow parking solution is working well overall but recommended continued review of lighting and traffic flow at times of high use.
Staff said the Brentwood Boulevard signal project and related widening should wind down by the beginning of fall, with the longest-lead item being the mast-arm delivery in early October.
