The Midlothian City Council tackled a number of infrastructure matters for the growing city at last Tuesday's semimonthly meeting, amending a agreement for a new four-lane street in the new Grove development; approving bids for a water treatment plant and pump station expansion; passing a manhole rehabilitation project; and awarding a bid for a total package of 12 road rehab projects.

The council approved a change in an agreement with The Grove that will allow the developer to build all four lanes as part of Phases 3 and 4 of the 133-acre development.

City engineering and utilities director Mike Adams told council members that Grove Branch Road extends from Walnut Grove Road and will ultimately tie in with the extension of Onward Road. The developer of The Grove was initially responsible for only two of the four lanes planned for this thoroughfare, but now wants to build all four lanes with help from the city in the form of reimbursement for road impact fees for the other two lanes.

The council also approved bids by Felix Construction Company for the Auger Water Treatment Plant expansion project, and by Crescent Constructors for a high service pump station expansion at that location.

For the plant expansion, the base bid amount was $3.364 million for the project, with an alternate bid amount of $401,000 and a contingency of $175,000 added on for a total of $3.941 million. The pump station project’s total bid amount was $1.272 million, which includes the base bid, alternate bid and contingency.

Adams said both projects have been budgeted and are part of he utility fund, and are well under budget. A second project for the treatment plant is in the works and will be presented to the council at a future date.

James Naylor, an engineer with the firm Freese Nichols, told the council the expansion will expand the capacity of the plant from eight million gallons of water a day to 12 million gallons. Improvements to the sediment basin and membrane feed pump as well as the addition of a pre-membrane strainer are the main components of the project.

Road rehab

The council approved a bid from Reynolds Asphalt for a package of 10 roadway rehabilitation projects . The base bid amount of $2.725 million, with a change order in the amount of about $281,000 to include two additional road rehabilitations.

Public works director Adam Mergener said road work is expected to begin as soon as weather improves, but some projects may be delayed by availability of work crews as well as utility and drainage work that must be completed before repaving can begin.

“Our intention is to complete these roads this calendar year,” Mergener said.

The original list of 10 streets to be rehabbed include either all or portions of Ashford Lane, McAlpin Road, Mount Zion Road, North 9th Street, Onward Road, Plainview Road, Tahoe Lane, Twin Oaks Road, Robinson Road and Eastgate Road. The two streets added to the project are Sudith Lane and Overlook.

The council also OK’d an agreement with Insituform Technologies Inc. of Corinth for a manhole rehabilitation system for the Airport and Harvest Hill trunk lines. The cost of the project is just under $150,000.

Mergener said the rehab is part of an ongoing project that is about one-third complete, with about 980 manholes to go. It will use the SpectraShield multi-layered liner system that is now required for new manhole construction in the city.
