Equalization Tank Study Update Presented to Committee

The Environment, Public Works, Planning, Zoning, and Development Committee reviewed an update on the equalization tank study. The city received $1.1 million from Congressman Max Miller for this study, authorized by Ordinance 2443 in June 2024. Manikin Smith, with sub-consultant Brown and Caldwell, is conducting the study to identify potential locations and sizing for storage basins to reduce basement flooding and overflow to Lake Erie. Three initial locations in the Rocky River service area were discussed: Bulkley Park, Bain Park, and Alexander Road. The study uses hydraulic models and basement flooding databases to identify problem areas. Storage can be above or below ground, with below-ground being preferred for less community impact. The models assess the reduction in water levels and potential basement flooding. For Bulkley Park, 1.1 to 1.3 million gallons of storage are needed. For Bain Park, approximately half a million gallons are needed, providing local flood protection but less peak flow reduction at the treatment plant. The Alexander Road area proposes using a large oversized pipe in the right-of-way for storage, potentially offering considerable peak flow reduction. The West 227th pump station service area also has flooding issues, and replacing existing pumps is recommended and planned. A potential storage basin near I-480 shows promise for reducing peak water levels in that area. Future steps include analyzing cost-effectiveness and determining the appropriate design storm, focusing on 5-year and 10-year storms. The study aims to provide data for informed decisions on storage basin locations and benefits, with a final report expected by the end of August.
