The city has set in motion the trestle repairs necessary for the Astoria Riverfront Trolley to operate next year.

The City Council on Monday night approved more than $23,000 for design services on a construction project estimated to cost $319,500. The city will use tourism money in the Promote Astoria fund to finance the project.

The city will focus on the 3 miles of track and four trestles used by the trolley between Portway Street and 39th Street. Councilors separately approved about $14,500 for repairs to the trestle along the Astoria Riverwalk near Alderbrook.

“If the trolley is going to run this next summer, this work has to happen,” City Manager Brett Estes said.

Annual maintenance costs will approach about $276,000 over the next decade. The city is in talks with the trolley association about sharing the costs.

“Well this is definitely a tough pill to swallow,” City Councilor Zetty Nemlowill said. “It’s not the first time we’ve heard about it, but the Riverwalk is of utmost priority in Astoria, so I don’t see that we have any other choice but to award this contract tonight.”

The city is also doing about $206,000 in emergency repair work to wooden bridges on the north ends of Sixth through 11th streets near the Riverwalk. The work is a temporary fix while the city moves forward with a $12 million project to replace the short, street-end bridges over the next few years.

In other business Monday night:

• The City Council updated a legal services contract with City Attorney Blair Henningsgaard. The agreement includes a $3,000 pay raise, from $84,000 to $87,000 a year. The rate Henningsgaard charges to handle nonroutine city matters will also go up by $10 an hour, from $180 to $190 an hour.
