Drivers beware: If you’re a Vancouver resident with out-of-state plates, the city is on the prowl.

The first wave of volunteers from the Neighbors On Watch group patrolled Vancouver neighborhoods last weekend on the lookout for out-of-state vehicles parked in residential neighborhoods. License plates were recorded and vehicles that could be out of compliance received an informational pamphlet on the law.

Some 10 percent of Vancouver residents have failed to register their vehicles in Washington state, and it’s costing the city more than $300,000 annually in Transportation Benefit District funding.

The funding — about $2.4 million annually — is generated by the district and a $20 license tab renewal fee that was implemented in 2016. Those fees are used to improve city streets, including fixing potholes and sidewalks.

The city’s $300,000 loss could double in mid-2018 if the city council, acting as the Transportation Benefit District Board, approves a recommended license tab fee increase to $40. That decision will be made in December.
