Consultants identify Vulcan Park, Bolken Park and Alexander Road as top EQ basin candidates

Consultants showed maps and cross‑section profiles of candidate locations in the Rocky River service area and described how each site would perform during short, intense storms. "If we put in storage at Vulcan Park near the upstream end ... about 1,100,000 gallons of storage," consultant Brian Rodney said, adding models show upstream sewer water levels could drop by more than 10 feet in some reaches.

A second park site south of West 210th (referred to in presentation as Bay/Bayonne Park) was modeled at roughly 500,000 gallons and would provide strong local basement-flood protection but limited peak‑flow benefit at the treatment plant because of its distance from that facility. In the Alexander Road area — where land is scarce — the team proposed an oversized underground storage pipe (60–72 inch diameter) that could store about 500,000 gallons as a constructability alternative to a buried tank and still provide downstream peak‑flow reductions.

Council members raised neighborhood impacts (for example, building under a soccer field) and were told that excavation would be backfilled and the surface reestablished after construction. Staff emphasized most proposed candidate sites are publicly owned or in public right‑of‑way; private‑site acquisition would require easements or purchases and is not part of the near‑term recommendation.

What happens next: the consultants will refine site-level cost, constructability and benefit scoring in the August report, and staff will confirm that recent sewer improvements are accounted for in the models before final prioritization.
