The San Ramon Valley -– most of it anyway -– will have a new county supervisor in the next couple of weeks.
On a three to two vote Tuesday, with both the former and future area representatives opposed, the Contra Costa County Board of Supervisors approved a redistricting that moves San Ramon, Danville and Alamo into Gayle B. Uilkema's district, District II.
Camino Tassajara, Blackhawk and Diablo will all remain in District III and will continue to be represented by Supervisor Mary N. Piepho.
Both Uilkema and Piepho backed Map 15, which would have kept city boundaries intact, although for slightly different reasons.
"It was less costly and it kept cities whole," Uilkema said. "It would minimize expenses and staff relocation."
Uilkema pointed out that with the redistricting plan approved Tuesday, one district would remain essentially the same, while 50 percent of the residents of the county would be represented by a supervisor they never voted for.
"They don't know who they are and we don't know who they are," she said.
Piepho said she supported Map 15 because it kept the San Ramon Valley intact. She said she didn't think the new map –- officially known as Map 17 D amended -– would serve the county well over the coming 10 years.
Map 15, Piepho said, had the least population differential, and came closet to achieving the demographic mix that was part of the reason for redistricting.
Uilkema said she thinks the San Ramon Valley fits her district, however, pointing toward a number of projects the valley is working on with the area known as Lamorinda, including transportation and the solid waste authority.
"I think there's a great deal in common," Uilkema said, adding, "The current map provides an excellent opportunity for a new approach."
Her next step is to reach out to her new constituents.
"That is our primary goal," she said. "There is an office in Danville. We have already contacted agents to see what facilities are available. I expect I will be attending as many functions as possible."
It was a bittersweet vote for Piepho, who said she was honored to represent the San Ramon Valley for the last seven years.
"I worked hard to have the opportunity and have built many relationships here," she said.
A final public hearing on the redistricting plan will be held Aug. 9.
