As Tom Croley drove slowly through the parking lot at Legacy Salmon Creek Medical Center, he and his partner trained their eyes on the dashboards of cars parked in spots marked for disabled visitors.Croley and Gary Anderson are among 10 volunteers who receive a limited commission from the Clark County Sheriff’s Office to write tickets for cars parked illegally in disabled spots.“People who are truly disabled should have those spots available to them,” said Anderson, whose wife is disabled and has a parking placard.Although Vancouver’s 2010 budget cuts eliminated the city’s volunteer enforcement program, the sheriff’s office program is going strong. Last year, volunteers put in 185.5 hours, issued 441 warnings and 99 citations, said Sgt. Shane Gardner, who oversees community programs for the sheriff’s office. Volunteers concentrate their efforts in Hazel Dell, Salmon Creek and other urban areas of unincorporated Clark County.Croley and Anderson can write tickets only outside city limits and only when they go on patrol, which they do a couple of mornings a month. They begin their shift by stopping at the west precinct office to pick up a ticket book and a white car they mark with magnetic signs.Croley, 65, who retired after 30 years of running a glass shop, wanted to volunteer as a sheriff’s reserve officer. Hearing loss prevented him from qualifying, so he signed up for the parking patrol.
