The City of Tacoma, WA, will accept bids Oct. 11 for recoating and related work on the spillway gates at Cushman Dam No. 1—a contract valued at $50,000 to $60,000.

The project involves recoating the upstream faces of two radial spillway gates, 40 feet wide and 20 feet high.

Scope of Work

The existing coatings are presumed to be non-hazardous, but the contractor must test to verify. If lead is identified, a change order will be executed for the use of a lead stabilizer.

 Cushman Dam, circa 1925

 University of Washington Libraries

An archived photo shows the partially constructed Cushman Dam No. 1 releasing water from two gateways around 1925. The dam was activated in 1926.

The gates will be abrasive blast-cleaned to SSPC-SP 10 and coated with a moisture-cured urethane system.

A site visit is required, and Sept. 28 is the only scheduled availability.

History, Licensing Flap

Tacoma Power built Cushman Dam No. 1 to provide hydroelectric power to the city of Tacoma.

The dam was activated on March 23, 1926, with the push of a button by President Calvin Coolidge in a ceremony at the White House, according to a history by the utility. A second, smaller dam, Cushman Dam No. 2, was completed by December 1930.

Using a "concrete arch" and "gravity and embankment" design, Cushman No. 1 consists of 90,000 cubic yards of concrete, with a top width of eight feet and a base width of 50 feet, at 275 feet high and 1,111 feet long.

In 2010, Tacoma Power received a new Federal Energy Regulatory Commission license to operate both dams until 2048.

The utility had applied for the licenses in 1974, but lengthy  legal and regulatory disputes held the dams to a series of temporary licenses until a settlement last year.
