WALNUT CREEK -- The City Council is expected Tuesday to debate whether to put a half-cent sales tax measure on the November ballot, even though two council members have repeatedly said they are opposed.

Some community and council members have repeatedly said they support an increase to the city's sales tax, which would generate $7 million for general use. But such a tax measure requires a supermajority -- four of five council members approving -- to get on the November ballot.

The City Council will hold a public hearing and vote whether to have such a ballot measure at its 7 p.m. meeting Tuesday, City Hall, 1666 N. Main Street.

Such a measure is something Councilman Justin Wedel and Mayor Kristina Lawson have steadfastly opposed. And even though Lawson has announced she will not seek re-election in the fall, she still does not plan on changing her mind, she said.

Supporters, from nonprofit groups to city council members say there is a structural deficit and the city needs more revenue to continue certain programs and services as well as maintain roads and buildings.

Opponents of such a tax increase say a clear need for more money has not been demonstrated.
