To help pay for the State-mandated Wastewater Plant upgrade debt and water and sewer line replacements, which would help reduce water and/or sewer rates in the City, shall the City of Placerville adopt an add-on sales tax (transactions and use tax) of one-quarter percent (.25%) for 30 years, with all proceeds going only to local water and/or wastewater debt service and water and/or wastewater construction projects, with annual oversight?
