Wayne County approves emergency design work after storm sewer separation near Belleville Lake
Summary
Wayne County commissioners accepted an emergency procurement report and heard details about designs to repair separated reinforced concrete storm sewer pipes on Old Denton Road in Van Buren Township; engineers say ground softening has created a void and slope-stabilization and easement access are needed before construction can begin.
Wayne County commissioners on the Committee on Public Services accepted an emergency procurement report and heard details Tuesday about engineering design work to repair a separated reinforced-concrete storm sewer on Old Denton Road in Van Buren Township near Belleville Lake.
Catherine Chung, executive project manager for Wayne County Department of Public Services, told commissioners the county discovered three separated locations where stormwater that should flow through the pipe is instead draining into the ground. "The ground is softening and, forming, in the formation of a sinkhole," Chung said, adding that the separation is creating a void the county wants to stabilize before it worsens.
The county sought an engineering designer and retained SoMAD Engineering for professional engineering design services, Chung said. Design work included a topographical analysis and geotechnical investigation to assess soil conditions and slope stability; the design took about four to six weeks and was completed last week, she said. Wayne County staff have identified a construction vendor but said construction cannot start until temporary easement language is secured to permit access from adjacent private property. Because of the slope angle and pipe size, staff said access by barge is not possible and the county will build an access road from private property once an easement is obtained.
Steve Shea, division director for Wayne County Roads, summarized that the procurement was processed as an emergency to secure design services and that the county is preparing for a separate emergency procurement for construction once access is secured. Commissioners asked about immediate public-safety measures; Shea said barricades are in place at the site.
The item was included in a motion to approve multiple items (items 1–9); the motion carried. The transcript shows the county presented the engineering findings and next steps but did not specify a construction start date.
The county described the work as focused on stabilizing the slope in addition to repairing the separated storm sewer to prevent further ground loss into Belleville Lake.
