Arroyo Grande City Councilman Joe Costello is running for a seat on the California Coastal Commission, he told The Tribune on Thursday.
Costello joins incumbent Commissioner Mary Ann Reiss, a Pismo Beach councilwoman, and San Luis Obispo Supervisor Bruce Gibson in seeking the appointment.
Brown put out a call for applicants Jan. 25, even though Reiss has been on the job for less than two months.
Then-Gov. Arnold Schwarzenegger appointed fellow Republican Reiss in December after Commissioner Katcho Achadjian resigned to take a seat in the state Assembly.
However, a coastal commissioner serves at the pleasure of the governor, and Brown is a Democrat, as are Gibson and Costello.
The position must be filled by an elected official from Ventura, Santa Barbara, or San Luis Obispo counties. Others beside Costello, Reiss and Gibson might apply, although none did in November.
The Coastal Commission, created by voters in 1972, has 12 voting members and three nonvoting members. The powerful -- and controversial -- board controls land use along California's coastline.
Reiss and Gibson said they expect the governor to make a decision within 45 days of Jan. 25, when he sent out the request for applications.
