How does pollution enter our waterways?

Runoff from our rooftops, parking lots, streets, and parks all discharges into the City’s storm drains. These storm drains are connected to our local waterways. That means pollutants such as litter, fertilizers, sediment, animal waste, and oil and grease can be picked up by runoff and washed into our creeks, and eventually the San Francisco Bay. That’s not only harmful to those critters that depend on our waterways, it also has the potential to impact public health and diminish local recreational opportunities.

What is the City doing?

The State of California has issued a Municipal Regional Stormwater Permit to municipalities and flood control districts in the Bay Area to regulate stormwater discharges. The City implements best management practices (BMPs) to control and reduce pollutant discharges into our storm drains during municipal operations such as road repairs and sidewalk maintenance.

In addition, the City does the following:

  • Inspects industrial and commercial sites likely to contribute to pollution of stormwater runoff.
  • Regulates new developments/redevelopments for effective stormwater controls.
  • Requires the implementation of sediment and other pollutant controls for construction projects.
  • Responds to illicit discharges.
  • Minimize trash getting to our waterways through active street sweeping, storm drain maintenance, and the deployment of trash capture devices.

What can you do to take care of our waterways?

  • Wash your car at a commercial car wash.
  • Keep your outdoor trash/waste containers closed.
  • Clean up spills immediately with dry methods. Never hose spills down the storm drain!
  • Check for and comply with the City’s stormwater requirements if you have a project that will create or replace 2,500 ft2 or more of impervious surface.
  • Regularly maintain stormwater treatment measures on your property. (If you have a maintenance agreement with the City, download the annual report form and inspection checklists here.)
  • Pick up your pet’s waste.
  • Report illicit discharges to the City at (925) 931-5500 or
  • Volunteer at local creek cleanup events!
  • Eliminate water runoff from irrigation by shortening watering time and adding multiple watering cycles. Visit for more tips on how to prevent water runoff!

  • Report in the Mobile Citizen App between the hours of Monday-Friday, 7 AM - 3:30 PM.

Stream Maintenance for Water Conveyance

Maintenance of stream sections and stormwater detention ponds is necessary to ensure proper water flow through streams, improve water quality, and reduce the risk of flooding. The City of Pleasanton conducted an environmental review to assess the potential impacts of implementing the periodic, routine maintenance activities on specific stream segments and stormwater detention ponds within the City of Pleasanton to improve water conveyance and quality. The resulting Negative Declaration is available below for the general public. Questions with regards to Pleasanton's Stream Maintenance Project can be sent via email to


  • Discharge anything but rainwater down the storm drain.
  • Dump paint or wash paint brushes down a storm drain.
  • Wash kitchen mats outside.
  • Scrub down trash containers with detergents and wash them into alley or street gutter.
  • Litter.
