A stormwater filtration system and a new street sweeper to help stop pollutants from flowing into Mill Creek is in the works for the city of Walla Walla.
The city has been chosen to receive a $466,390 grant from the state Department of Ecology for the stormwater project, to be built at the intersection of Isaacs Avenue and Rose and Main Streets. A second grant of about $330,000 will be used to buy a high-efficiency air sweeper to double the volume of sediment and debris collected from city streets.
The award was among 162 projects statewide that will receive grants and loans worth $227 million for water quality projects, said Ecology spokesman Sandy Howard. The money is included in the biennial budget Gov. Jay Inslee signed in June.
