Birmingham commissioners debate replacement of century-old retaining wall after ADA, erosion and safety concerns

A prolonged discussion March 9 centered on a large retaining wall system along Brookside, Ravine and Park Streets that engineering and a structural consultant identified as showing movement, voids under the sidewalk and areas where cross slope exceeds ADA limits.

Staff briefed the commission on historical work (original walls built in the early 20th century, partial replacement in 1991) and shared site photos and video inspections showing cracks, voids and heaving. The engineering presentation noted the wall and adjoining sidewalks are failing in places and that the sidewalk cross slope measures as much as about 8%, well above the 2% threshold for ADA accessibility. The department said the lowest responsive bid to replace the retaining wall alone was roughly $681,900; the broader asphalt-resurfacing program budget is about $2.1 million.

Commissioners and residents debated three central questions: 1) what is the minimum corrective work to bring sidewalks into ADA compliance and limit city liability; 2) whether the city should pay the full cost or use special assessments to allocate some cost to adjacent property owners who most directly benefit; and 3) whether the proposed split-face modular wall (the material shown in the packet) is acceptable in this historic neighborhood.

Several commissioners said proactive replacement is preferable to repeated patchwork and to the risk of future emergency failures. Others urged more community outreach and clearer visuals of what the new wall would look like before construction. Staff said phasing and construction techniques would aim to protect existing private improvements; department forestry staff will review trees that may need removal. The city attorney read relevant ordinance language and advised the commission that, when a special assessment applies, the commission may not execute construction contracts for the assessed improvement before the role is confirmed.

Action: after extensive debate the commission voted to proceed with replacement as part of the 2025–26 asphalt resurfacing program and set a public hearing of necessity (April 13) and, if necessary, a confirmation hearing for April 27 for the assessment role. Staff were directed not to execute contracts tied to assessments until notice and confirmation steps are complete. Commissioners also asked staff to provide renderings and clearer materials for neighborhood review prior to final contract execution.

Why it matters: the project raises technical, legal and equity questions: ADA compliance and liability push toward timely repair; procurement and bid-timing pose cost and schedule risks; and decisions about special assessments determine which residents bear replacement costs and which costs the city absorbs.

Follow-up: staff to provide design renderings, a refined cost breakdown (wall vs. sidewalks vs. roadway) and detail on tree impacts; public hearings on necessity and role confirmation were scheduled in April.
