Tonight’s City Council meeting will be long and potentially controversial.

Councilwoman Irene Sundberg is expected to ask the council to take action regarding increased explosives testing planned for the Lawrence Livermore National Laboratory’s Site 300 in the hills west of Tracy, although the city has no jurisdiction over the site.

And a four-person subcommittee of the appointed Tracy Tomorrow and Beyond, an advisory group to the council, is expected to tell the council that the community does not yet have enough information to make a judgment on a proposed anti-biological terrorism laboratory that the Department of Homeland Security is considering building at Site 300. The group was charged in September with researching plans for the laboratory and giving recommendations to the council.

In other business, the Parks and Community Services Department is expected to ask the council to approve an agreement with the Tracy Unified School District that would open the soon-to-be-built swimming pool at West High to the public during summer.

The Public Works Department is expected to ask the council to spend $90,000 for buying and installing a water clarifier at John Jones Water Treatment Plant. The employees will ask the council to award the contract to Westech Engineering, less than a month after Sundberg asked the department to cut back on its no-bid purchases.

“No other manufacturer’s drive will fit the existing clarifier equipment, so a sole-source purchase is necessary,” wrote Deputy Director of Public Works Steve Bayley in a memo to the council. “In this instance, competitive bidding would be meaningless and impractical.”

Councilwoman Evelyn Tolbert is expected to outline a plan to help increase the affordability of housing in Tracy during a council debate on how best to implement Tracy’s new general growth plan.

Economic Development Director Andrew Malik is expected to present an update on plans to bring a college to Tracy.

The council might also give city attorney Debra Corbett direction to prepare an ethics code for Tracy’s political leaders or employees.
