Here is a look at some of the regional measures and tax initiatives recently passed:Sonoma County

Measure M -- Gravenstein Union School Bonds. A general obligation bond that will raise up to $6 million for the Gravenstein Union School Distrct passed with 65 percent of the vote. Bonds will go toward upgrades at school facilities. The funds to repay the bonds would be raised by an increase in property taxes on land and improvements in the district.

Measure N -- Roseland School Bonds. Nearly identical to Measure M, except it expects to raise up to $7 million.Napa County

Measure S -- Airport Improvement. Changes weight requirements for the runway at Napa County Airport and would allow repairs and replacements according to Federal Aviation Administration standards. Would not change the classification of the airport, which does not receive commercial flights.

Measure T -- Sales Tax.  A sales tax that is expected to raise $11.2 million per year to fund improvements to the county's aging and damaged roads and other improvements. 

The measure will replace a current half-cent sales tax that voters approved in 1998 to pay for flood control. It  will take effect in July 2018, when the flood tax is set to expire, and run for 25 years. Over that span, the sales tax will generate an estimated $282 million, with 99 percent of that going toward road repair. That amount will also be split up between the six municipalities of Napa County. The county and the City of Napa would get 80 percent of funds, while Calistoga, St. Helena, Yountville and American Canyon would divide the rest.Marin County

Measure A -- Sales Tax Increase. The measure will raise more than $10 million a year for parks, open space and farm programs. Over nine years, the sales tax increase will raise more than $90 million, with 65 percent going toward the parks budget, boosting it by 54 percent. Roughly $1.3 million per year would go toward the purchase of open space, while about 20 percent of the tax dollars will go toward farm programs.
