RIDGEFIELD — Clark County should carefully look at how it pays for public safety, and do so in a way that takes into consideration costs to the entire justice system, Commissioner Steve Stuart said Thursday.At the commissioners’ annual retreat at Tri-Mountain Golf Course in Ridgefield, Stuart questioned whether it was prudent for the county to assume it could set aside money to recruit, train and hire new deputies without that affecting the criminal justice system. The comments came in response to a presentation by Bob Stevens, county budget director. On the direction of the sheriff’s office, Stevens suggested adding eight deputies to bolster an office that’s seen its numbers decline in recent years.The sheriff’s office is allowed to hire up to eight deputies in a year, based on the number of available graduation dates allocated by the state’s police academy, Stevens said.But Stuart said he wanted more information about the long-term budgetary effects of hiring more deputies. In addition, he said he wanted to know where the money would come from. Adding eight deputies would cost the county roughly $1 million a year.“It’s more complicated than just getting eight deputies,” Stuart said, adding he supported hiring more deputies as long as certain trade-offs were addressed.
