Here is roundup of results for special district races in East Contra Costa. Results are unofficial as of press time Wednesday morning, although all precincts have reported.

Discovery Bay Community Services District

Bill Pease, a former Fremont city councilman, and incumbents Mark Simon and Ray Tetreault won the races for the Discovery Bay Community Services District board.

In the race for two four-year positions, Pease had 39.6 percent of the vote and Simon had 38 percent. Incumbent Jim Mattison had 22 percent.

In the race for a two-year seat, incumbent Tetreault led with 61.5 percent, followed by Michael Temby with 38.2.

The main issue for the Discovery Bay district is improving its aging water capacity and distribution system, as it is looking to sell about $14 million in municipal bonds for a new water well and five wastewater projects.

Los Medanos Community Health Care District

Two candidates, including an incumbent who died, won two seats on the Los Medanos Community Health Care District board.

Board member and longtime community activist Darnell Turner, who died in September, garnered 39.6 percent of the vote, followed by incumbent J. Vern Cromartie, who had 34.7 percent. Challenger Joe Rubi, a former board member, had 25 percent.

Turner's death occurred at a time when it was too late to take his name off the ballot. His position will be filled by an appointment made by the districts's board of directors.

Ambrose Recreation and Park District

An incumbent and a challenger won two seats on the Ambrose Recreation and Park District.

Incumbent Eva Garcia had 40.5 percent of the vote, followed by Lee Mason, who garnered 34.8 percent. Mason, who used to work for the district, ran unsuccessfully for a seat in 2010. Terrillynn Kopita, who was appointed last year to fill a vacant seat, trailed with 24.3 percent.

While candidates for the Ambrose Recreation and Park District had different priorities, all three indicated supported a master plan that calls for building a controversial children's activity pool at Ambrose Park.

Ironhouse Sanitary District

Two incumbents and a challenger won three open seats on the Ironhouse Sanitary District board.

Michael Painter and David Contreras had 23.9 percent and 23.3 percent of the vote, respectively. Doug Scheer was third with 19.1 percent, followed by Aaron Meadows and Michael Burkholder, each with about 16.8 percent.
