Most Local Measures, Incumbents Lose : Municipalities and special districts: A proposed bond issue for Sulphur Springs school district fails, but Santa Clarita’s annexation of three neighborhoods succeeds.

Voters rebuffed government-backed measures and most incumbents in a hodgepodge of municipal elections in northern Los Angeles County, according to final election results released Wednesday.

Sulphur Springs

Backers of Measure CK in the Sulphur Springs Union School District were disappointed after the defeat of the $30-million proposed bond issue to renovate schools in the Canyon Country district.

“I think we ended up being a victim of a negative atmosphere,” said Richard Keysor, a former school board trustee who ran the campaign for the measure. But supporters remained optimistic because the measure, dubbed CK for Classrooms for Kids, fell just short of the two-thirds vote needed for passage, a showing that could set the stage for a future ballot effort, Keysor said.

San Fernando

Voters rejected Proposition O, which would have repealed a 1986 initiative preventing the City Council from leasing the former police station without first holding a special election. It asked voters to permit the council to lease the building on its own, while still requiring an election to approve a sale or transfer. The tally of negative votes was 53%.

Santa Clarita

The passage of Measure Q in the Santa Clarita Valley will add three unincorporated neighborhoods and a total of 5,000 residents to the city of Santa Clarita. Measure Q was approved 1,080 to 1,014, a slim margin showing that many distrusted the young city and did not want additional government, opponents said.

Topanga District

The focus of an unusually raucous campaign was environmental activist Glenn Bailey, who edged out incumbent Nancy Helsely. Incumbents Jerry Douglas and David Gottlieb won reelection to the other two seats on the board, which advises landowners in the West Valley and east Ventura County on soil and water conservation.

Bailey said he had hoped to replace Gottlieb or Douglas, whom he has called pro-development. They have called him confrontational.

Antelope Valley

Ads for incumbents Clyde Kelly and Michael Schafer touted a combined 40 years of service on the board of Antelope Valley Hospital Medical Center in Lancaster. But the two polled only 16% of the vote each.

Teacher Steven Fox had 24.5% and registered nurse Anne Brouillette won 43.4%. Brouillette said her victory was only partly attributable to the fact that she raised more than $8,000, far more than the other candidates. She said the results reflected discontent among hospital staff and clients concerning employee relations and the cost of medical care.

Castaic Lake

Winning election to the agency that distributes water from the California Water Project to the Santa Clarita Valley was Stephen J. McLean, a civil engineer, who beat out incumbent Charles M. Brogan.

Robert J. DiPrimio held off newcomers Michael Sellheim, a civil engineer, and Robert Lathrop, a community activist. Mary R. Spring and H.G. (Gill) Callowhill ran unopposed.
