MISSOULA, Mont. -

The City of Missoula is doing some spring cleaning with the start of its street sweeping program.

Street Maintenance Superintendent Brian Hensel says people who park on the streets need to take a look at the cleaning schedule, and park their vehicles accordingly.

"It helps us to preserve the air quality in Missoula that we are mandated to perform sweeping for, and also removing the particulate on streets helps keep it out the storm drains, and water disposal facilities all over town," said Hensel.

Hensel also asks that people to make sure they keep yard waste and building materials off the road. Leaf pickup isn?t until the fall.
