Commission approves TDEC stormwater change order after engineers find deeper damage at injection well
Summary
Hamblen County commissioners approved Change Order No. 2 on a TDEC stormwater infrastructure grant after staff outlined added work and cost adjustments at multiple sites, including a $95,000 increase at Deerwood Shadows and a $15,000 correction at Brady Drive; the changes are funded by the grant and must be completed before the grant deadline.
Hamblen County commissioners approved Change Order No. 2 to projects funded by a Tennessee Department of Environment and Conservation (TDEC) stormwater infrastructure grant after staff outlined newly discovered site problems and associated cost adjustments.
Planning and zoning manager Tommy McKinney told the commission that field crews uncovered deeper damage than expected at the Deerwood Shadows injection well, requiring additional piping and an approximately $95,000 increase. He said Brady Drive’s outlet pipe will require corrective work, revising an earlier $5,000 estimate to $15,000. McKinney also said the planned paving for Brandy Drive (previously estimated at $97,500) has been set aside because the state highway department can likely complete that work more cheaply; Robin Circle was added to the grant work at about $75,000. McKinney emphasized the adjustments are being paid from TDEC grant funds, not county match dollars: “This is TDEC money. We’re not talking about anything as far as county match money.”
Commissioners asked whether the projects were bid as a package and about the bidding process; staff said the projects were bid together with multiple bidders but that some change orders reflect work that was determined necessary only after crews began work. McKinney said the work covered by this change order must be completed by Aug. 30, 2026, and that TDEC will inspect sites.
Commissioner Harville moved to approve Change Order No. 2 and Miss Howell seconded. The motion passed by voice vote. The approved change order reduced the originally proposed change-order total from $332,500 down to roughly $245,000 after scope adjustments, McKinney said; he also said two sites originally targeted will not be pursued because of time constraints.
