SALEM, Ore. -

Oregon Secretary of State Kate Brown and Central Oregon county clerks are reminding voters that ballots for the May 21 election are being mailed out starting Friday.

"I urge all registered Oregon voters to cast a ballot," Brown said. "There are important local ballot measures and races for school boards, community college boards and special districts across Oregon."

Voters who do not receive their ballot by Wednesday, May 8, should go to My Vote to see if their ballots have been mailed. Otherwise, voters should call their county elections office.

Ballot measures to be decided in the May 21 election include proposals to ban retail single-use plastic bags in Newport, an $82 million school serial levy in Beaverton and a $18.3 million measure to fund 9-1-1 services in Deschutes County.

Contested school district races will be decided from Lake Oswego and Forest Grove to Medord, Bend and Lincoln County.

Contested special district races include the Corbett Fire District, the Bend Metro Park and Recreation District and the Port of Newport.

Contested community college board races range from Portland to Central Oregon to the Rogue Valley.

Ballots must be received by county elections officials no later than 8 p.m. on Tuesday, May 21.
