ALAMEDA -- Park Street is set to get some spring cleaning.

The city of Alameda plans to spend between $5,000 and $10,000 to deep-clean sidewalks and garbage cans on both sides of Park Street from Encinal Avenue to Lincoln Avenue beginning in May.

"It's going to be great," said Robb Ratto, executive director of the Park Street Business Association. "We haven't done this since about 12 years ago. We used to do it quarterly, but didn't have the funds to continue. We really appreciate the city and community going to bat for us to get this done."

Earlier this month, four contractors hoping to get tapped by the city showed off their skills at removing years of built-up grime, gum and discoloration. Those businesses trying to get the work include First Building Maintenance of Oakland and San Francisco, Peralta Services Corporation of Oakland, Ultra Wash Inc. of Castro Valley, and Universal Building Services of Richmond.

The contractors rely on machines to collect hot water used in the cleaning process, so "waste and any chemicals on the sidewalks do not go down the storm drains," said Richard Salles, a district manager for Universal Building Services.

"The city is working closely with the Park Street Business Association and West Alameda Business Association to increase the budget for regular sidewalk pressure washing," said Liam Garland, administrative services manager for Public Works.

"If successful, this washing will expand to more blocks. Webster Street's sidewalks are in better condition than Park Street's, largely because Webster Street has had some pressure washing in the last few years," Garland explained.

The city expects to decide which East Bay contractor will clean the sidewalks on Park Street by the end of April.
