Sewer rates for homes and businesses served by the West Bay Sanitary District will be rising by 9 percent starting July 1.
In a unanimous vote on April 23, the district's five-member board approved the increase, most of which will go to pay off bonds and low-interest loans for a $527 million capital improvement program, District Manager Phil Scott told the Almanac.
The district serves Menlo Park, Atherton, Portola Valley and areas of Woodside, East Palo Alto, and unincorporated San Mateo and Santa Clara counties.
For all but 60 homes in Portola Valley, the current $820 annual residential rate will rise to $893. The $1,042 rate in parts of Portola Valley would rise to $1,136.
