KEC Engineering given Leach Canyon Dam spillway restoration contract


KEC Engineering has been awarded the contract to repair and restore the spillway infrastructure for the Leach Canyon Dam in Lake Elsinore.

A 5-0 Riverside County Board of Supervisors vote Feb. 25 awarded a $728,819 contract to the Corona company while waiving a minor bid irregularity which did not affect the competitive bid process or the price. The county supervisors act as the board of the county’s Flood Control and Water Conservation District, and it was in that capacity that the contract was awarded.

A February 2019 storm damaged the spillway of the dam at the end of Amorose Street. District staff began developing plans for the repair of the spillway, and the board of supervisors authorized the advertisement for bid Nov. 19. The spillway restoration project will include the construction of two cutoff walls, grouted rock areas, a 3-foot-tall grouted rock weir and grading.

The Nov. 19 action set a Dec. 19 deadline for receipt of bids. Eight contractors submitted proposals, and the KEC bid of $728,819 was the lowest. Although KEC omitted the company’s employee identification number, it did not create an unfair advantage or affect the price of the bid. The bid was found to be otherwise responsive, KEC has provided the bonding and insurance documents the contract requires, and no protests were received.

The Western Riverside County Multiple Species Habitat Conservation Plan requires the district to pay the Western Riverside County Regional Conservation Authority up to 3% of the total capital costs as required mitigation for the construction of flood control facilities. That mitigation funding is $21,664, which brings the total expenditure to $750,683 not including district staff time costs.

The contract is designed to meet federal regulations which could allow Federal Emergency Management Agency reimbursement for some or all of the expenses.
