Contra Costa Times has the details:

Measure WW put on the ballot by the East Bay Regional Park District got 71 percent of the vote, more than enough to pass the two-thirds majority it needed.

Measure WW will finance $500 million in bonds over two decades by extending a property tax of up to $10 per $100,000 in assessed valuation in almost all the two counties. Only the greater Livermore area is excluded because it was not part of the regional park district in 1988 when voters approved the property tax increase to buy and develop parks.

Passage of Measure WW will enable the East Bay Regional Park District to continue an aggressive land-buying campaign that has expanded the park system by some 34,000 acres in the last two decades. It now has 98,000 acres in 65 parks.

Here’s one of the projects it would fund:

Project Location: Calaveras Ridge Trail
Project Number: 12
Project Description: $11.3 million to acquire open space and park corridor and construct this trail for all users connecting six regional parks along the 680 corridor serving all communities from Sunol to the Carquinez Strait.

Now that would be a nice stretch o’ trail.
