Storm Sewer Service Charge Rates

The Storm Sewer Service Charge rate structure charges users of the storm sewerage system in San José based on the relative quality and quantity of stormwater runoff contributed by residential, commercial, institutional, and industrial properties. The rate structure apportions the costs of storm sewer service to properties in proportion to their relative contribution of flow and pollution to the storm sewer system.

Rates are computed to recover projected costs of the following:

  • Stormwater pollution control and permit compliance
  • Management, operation, maintenance, and rehabilitation of the storm sewer system
  • Improvements to the storm sewer system
  • Street sweeping
  • Administrative services

Storm Sewer Service Charge rates are reviewed and adjusted annually, as cost and service demand levels change. The current rate structure for storm sewerage services described below became effective July 1, 2011, with San José City Council adoption of Resolution No. 75857 on June 14, 2011. The rates are structured for the estimated cost recovery requirements and the service demand levels of Fiscal Year 2011-12.

For Fiscal Years 2013-14, 2014-15, 2015-16, 2016-17, 2017-18, 2018-19, and 2019-20, no rate increases were adopted. Rates maintain at the same level as Fiscal Year 2011-12.
