Commission votes to replace failing retaining walls after engineers flag ADA, erosion risks

Engineers told the Birmingham City Commission that several retaining-wall segments in the Brookside/Ravine/Park area are moving out of plumb, have voids beneath sidewalks and are producing cross slopes well above the 2% ADA limit. That account of erosion and degraded sidewalks prompted a months-long policy question: who pays and how should the work be prioritized?

Engineering staff (speaker S8) summarized field video and photos showing cracked pipe lines of soil movement and areas where the sidewalk cross slope exceeded 8–10%. "In this location right here, the slope of the sidewalk is about 8%... the ADA requirement is 2% or less," staff said during the presentation, arguing the city was on notice of a known defect and should act to avoid liability and loss of public sidewalk access.

Staff estimated the wall-only construction costs at roughly $681,900; the larger asphalt-resurfacing contract for the season was about $2.1 million. Commissioners debated alternatives including partial repairs, relocating sidewalks to street level, tree impacts and aesthetics. Concerned residents and commissioners said the neighborhood’s historic character should be considered when selecting wall materials; staff said split-face block colored to match existing stone was proposed so future utility access is easier and sections can be removed and replaced without cutting monolithic concrete.

A central policy question was assessment: part of the wall sits on public ROW and supports the roadway and sidewalk; parts of the wall abut private upper terraces and could be argued to primarily benefit adjacent property owners. Commissioners reviewed historical practice: a substantial portion of the wall had been replaced in 1991 at city expense and prior special-assessment precedent was mixed. Legal staff reminded the commission of ordinance language requiring confirmation of a special assessment roll before certain related construction expenditures can be executed.

After deliberation and a brief delay for additional research, the commission adopted a resolution to proceed with replacement of existing retaining walls and set a public hearing of necessity and a confirmation hearing schedule (public hearing on necessity set for April 13, 2026; if necessity is found, confirmation hearing on April 27, 2026). The motion passed by roll call with one commissioner recorded as opposed.

What residents can expect: staff said the project will be phased to limit impacts to private property, that forestry will review trees that may need removal, and that staff will return with project renderings, final cost estimates and a clearer breakdown of which property owners would be assessed under the city’s ordinance.

Representative quote from resident Stuart Raider (speaker S16): "Since 2020, I estimate that I have involved the Birmingham Police Department close to 50 times due to excessive noise and disturbance and vibrations in my floor coming from the business and its patrons." (context: earlier in the meeting, distinct public hearing on liquor-license renewals raised separate quality-of-life concerns.)

What’s next: staff will provide formal project renderings and a finalized special-assessment roll and proceed with the scheduled public hearings in April 2026; the commission instructed staff not to execute contract expenditures that would trigger the ordinance until the assessment confirmation process is complete.
