Hiram staff recommend geotechnical cores for Nebo Road to target repairs; SPLOST funding eyed
Summary
City engineers proposed a geotechnical study of Nebo Road with about 35 core borings to determine whether targeted resurfacing or full-depth reclamation is needed; engineers said work would be phased and paid from SPLOST, with a rough upper-bound rebuild estimate of about $1.5 million per quarter- or third-mile depending on findings.
City engineers recommended a geotechnical study for Nebo Road intended to guide targeted repairs and help prioritize construction phases.
Michael (public works/engineering) told the council the study would involve roughly 35 core borings along the road to evaluate subsurface conditions. That information would allow staff to identify sections requiring full-depth reclamation, sections needing resurfacing, and where patchwork will suffice to extend service until larger work can be scheduled.
Michael said the work will be paid from SPLOST funds and is a supplement to prior engineering efforts; he explained that smaller, better-defined project scopes will be easier for contractors to bid on and that the city has already done a first round of engineering that drew no bidders because the jobs were too small and fragmented. He emphasized the study’s goal is to provide the technical basis for a phased, multi-year repair program rather than an immediate full-road rebuild.
When asked for cost estimates, Michael said final numbers depend on what the study finds and cautioned that resurfacing costs differ substantially from full-depth rebuilds. He gave a broad illustrative figure — noting uncertainty — that a full-depth reconstruction could be on the order of $1.5 million per quarter- or third-mile, but said that may be higher or lower depending on subsurface needs.
Council members asked about traffic increases from nearby subdivisions and the expected effect of Highway 92 construction; Michael said engineers can incorporate projected usage into recommendations for widening or other design choices if warranted.
Council directed staff to proceed with the geotechnical study and to use the findings to plan phased repairs and to refine cost estimates and bidding strategy.
