INTRODUCTION                  How Are We Doing?

When it rains in the City of San Luis Obispo, do you know where the water is collected?  Storm water runoff does not go to treatment plants as one might think.  Instead, storm water drains into the City's curbs and gutters, pipes, open channels and other types of community retention basins, such as parks, local lakes and creeks.  Remember, You are the Solution to Storm Water Pollution!

The City's Storm Water Program has been created to help educate the community on environmental regulations.  San Luis Obispo works with state and federal regulators to make sure residents, businesses, contractors and the general public know the effect of storm water drainage and how they can help reduce the number of pollutants that enter the storm drain system.  As part of this effort, the City offers free training seminars in what are called Best Management Practices s throughout the year to certain target industries (i.e. automotive, construction , food services, janitorial services, pressure washing and etcetera).   For a current list of up-coming free seminars by industry please click here!

The City’s Public Works and Community Development Departments are responsible for coordinating the implementation of the City’s Storm Water Management Program.  This comprehensive Program is required under the Phase II Storm Water Regulations regulated by the State Water Resources Quality Control Board (“SWRQCB”), San Luis Obispo Region.  The primary goal of the Program is to minimize urban runoff that enters the municipal storm drain system, and carries bacteria and other pollutants into our local creeks, our watershed and to the ocean.

 As part of these new requirements, the City of San Luis Obispo has been mandated to establish a set of minimum-designated Best Management Practices (“BMP’s”) and Pollution Prevention Methods (“PPM’s”).  BMP’s are steps taken to minimize or control the amount of pollutants and runoff.  PPM’s are strategies to eliminate the use of polluting materials, and/or not exposing potential pollutants to rainwater or other runoff.  These BMP’s and PPM’s apply to all aspects of daily life within the City of San Luis Obispo.  For use specific information click on the following:
