Two contracts related to continued development of the Washington City Landfill were approved Monday night by the city council.

The project will involve opening Phase IV, the fourth of five planned “cells” in the landfill on the Struckhoff Farm off Bluff Road.

City Administrator Jim Briggs said when this cell is filled it will be near the end of the current lease of the property. But, he said, the city is negotiating with the Struckhoff family to extend the lease to include the fifth planned cell.

The council approved one contract with SCS Aquaterra for engineering and supervision services related to the project. The estimated cost for services provided by the firm is $77,900.

A second contract was awarded to J.H. Berra Construction Co. Inc. for actual construction of the fourth cell.

Briggs said the plan is to open the fourth cell, then excavate a portion of the first cell and relocate trash from it to the new cell.

That is being done to bring the city into compliance with the Missouri Department of Natural Resources which cited the city several years ago for overfilling Phase I, Briggs explained. That was due to a surveying error, he said.

Berra’s base bid for building the new cell is $535,777, compared to a $586,923 bid from K.J. Unnerstall Construction Inc., and $604,087 from Twehous Excavating Co. Inc.

The engineer’s estimate for the base bid was $750,000.

All three companies submitted alternate bids to excavate cell No. 1 and move the overfill to the new call. Those bids were Berra, $422,500; Unnerstall, $207,800; and Twehous, $214,495.

The city staff recommends utilizing city street department workers to relocate the overfill trash.

“We think we can do it for $100,000 to $110,000,” Briggs said. That would include renting some larger equipment and trucks.

That work would start once the new cell is completed.

Briggs recommended relocating the trash during the winter months and probably at night, due to the odor that will be involved in opening up the first cell.

That trash has been buried and decomposing for about 10 years, he told the council. “It’s got to be pretty ripe.”

The vote was unanimous to authorize the contract with SCS Aquaterra.

The contract with J.H. Berra was approved on a 6-2 vote. Councilmen Jeff Patke and Steve Sullentrup voted no.

The area where the fourth cell is planned is approximately 3 acres in size.

The city began developing the landfill in 1997 under a 20-year lease of the farm property.
