PLEASANTON -- The Pleasanton Ridge Regional Park will expand by 232 acres with a $2.2 million land purchase that will improve public access to the popular park.

The East Bay Regional Park board gave final approval Tuesday to buy the land in western Pleasanton from the Castleridge Property owners.

Most of the land has steep hills with oak trees, but the property also has some lower and flatter areas likely suitable for a new entrance to the 8,000-acre-plus Pleasanton Ridge Park, district officials said.

The site off Old Foothill Road is just southwest of the city of Pleasanton's Alviso Adobe Community Park. To view a map, visit http://bit.ly/LR6IWi and scroll to page 92.

The park district's Measure WW park bond measure will provide at least $1.2 million of the purchase cost. The park agency is applying to get the other $1 million from an Alameda County open space fund financed by a surcharge collected on trash dumped at the Altamont Landfill near Livermore.
