In April 2017, a majority of Palo Alto property owners voted to approve a new Storm Water Management Fee that would replace the previous 2005 storm drain fee, which was scheduled to sunset on June 1, 2017. The new fee is effective as of June 1, 2017. The new fee includes the Stormwater Measures Rebates Program that was introduced in 2008 and it is funded at a rate of $125,000 per year. The goal of this program is to help Palo Alto residents, businesses, and City departments implement measures that will reduce storm water runoff into the storm drain system and improve the quality of the runoff.

Example measures include:

  • Capturing rainwater in rain barrels or cisterns for use on landscaping and gardens
  • Constructing or reconstructing driveways, patios, walkways, and parking lots with permeable paving materials, so that rainwater soaks into the ground
  • Constructing a green (vegetated) roof to absorb and filter rainfall
