Unions and developers are among the supporters reaching into their pockets to make last-minute contributions to some of Lamorinda's 13 city and town government hopefuls.

Meanwhile, a pair of sales tax measures are snagging their fair share of financial backing during the final stretch of election season.

Fundraising totals released for a period beginning Oct. 1 show several candidates received modest financial boosts before Oct. 20, the cutoff date they're required by state law to report contributions received before the Nov. 6 election.

Supporters also gave to groups backing Measure L, which would raise Orinda's sales tax by a half-cent for road repairs, and Measure K, which calls for a 1-cent sales tax increase in Moraga to prevent deterioration of the town's roads.

In Moraga, where five candidates are vying for three open seats, candidate Philip Arth and incumbent Karen Mendonca outraised Mayor Mike Metcalf and challenger Roger Wykle. Arth received $2,639, mostly in contributions of less than $100. Mendonca, who at $9,883 has raised more money than any other Moraga candidate, received $1,511 in monetary support. Candidate Seth Freeman did not report contributions greater than $1,000.

In Lafayette, council hopeful Traci Reilly received the biggest gain, outpacing challengers Robert Lobron and planning commissioner Mark Mitchell. Her campaign finished the period with $5,305 in new contributions, bringing the fundraising total to $10,874.

Campaign disclosure statements show Reilly's committee received $250 from County Supervisor Candace Anderson and $1,050 from James Wardy of Comstock Capital. Reilly also received a donation for $100 from Brian Hirahara, president of Walnut Creek-based real estate developers BH Development. Incumbent and vice-mayor Mike Anderson was on vacation and did not file a statement; challenger Yolanda "Jolie" Vega is not fundraising.

Hirahara's company also donated to Orinda council incumbent Victoria Smith's campaign, which pulled in $4,175 during the final reporting period. Other individual donors include planning Commissioner Carlos Baltodano, Sil Garaventa of Concord Disposal Service and Richmond Sanitary municipal relationship manager Bielle Moore.

Smith's campaign also received an additional $500 from IBEW Local 302, a Contra Costa County electrical workers union; $500 from the Northern California Carpenters Regional Council, an Oakland-based builders and construction worker's union; $250 from Teamsters Local 315 in Martinez and $1,000 from Operating Engineers Local 3, which represents heavy equipment operators, construction workers and others.

Incumbent and current Mayor Steve Glazer, whose committee has received financial support from a variety of individuals including former California senator Don Perata, got help from Baltodano and from fellow council member Sue Severson. Michael Dieden, of developers Creative Housing Associates, donated to Glazer's campaign; so did Stephen Burns, manager of California Government Affairs at Chevron. Those and other donations bumped Glazer's overall contributions to $33,892, the most received in Lamorinda. Council challenger Linda Delehunt chose not to accept contributions.

Some Orinda residents and other individuals and companies also showed their support for Measure L, which is the first part of a four-phase plan to repair and maintain the city's failing roads. "Fix Orinda Roads Now!" has received $32,754 in total contributions to date, including from council members Sue Severson and Amy Worth and Oakland-based Pacific Trenchless, Inc., a pipeline company. In Moraga, backers of Measure K have raised $10,558 so far, including donations from council member Howard Harpham, candidate Arth and the Moraga Chamber of Commerce.
