Columbus presents alignment refinements for large transmission main; Dublin staff to coordinate on easements and outreach
Summary
Representatives from Columbus updated Dublin City Council on alignment refinements for the Home Road water plant transmission mains (two 48‑inch mains), described corridor evaluation and pairwise comparisons, easement needs within Dublin, phasing, tunneling under the Scioto River, and a plan for continued resident and stakeholder outreach.
Representatives from the City of Columbus and their consultants presented an update on the Home Road water plant transmission mains and alignment refinements affecting Dublin. Tim Huffman and the project team reviewed a multi‑corridor evaluation using pairwise comparisons, explained that the design includes two 48‑inch mains across the corridor, and described refinements intended to reduce traffic and construction duration impacts by shifting alignments onto existing links or alternative streets.
Presenters said they will seek four easements from the City of Dublin and conduct additional field surveys and environmental work as design advances to 90%. Council members pressed for careful coordination around Muirfield Drive (to protect median trees and preserve the streetscape), school outreach for construction timing and pedestrian routing, and community visuals to show the scope of work. On river crossings, presenters said microtunneling is the likely approach for getting mains under the Scioto River.
