Zone 9 – San Luis Obispo Creek Watershed


The Zone 9 Advisory Committee was formed to assist the San Luis Obispo County Board of Supervisors on policy decisions relating to Zone 9. The Advisory Committee assists in determining the needs, desires, and financial capabilities of property owners in Zone 9. The Advisory Committee also recommends specific programs to alleviate and control flood damage, with recognition of the ecological and aesthetic values of the programs.


The guiding document for Zone 9’s goals and objectives is the SLO Waterway Management Plan (WMP) which was developed and adopted in March 2003. The SLO WMP consists of three (3) volumes. Volume I contains a detailed hydrology and hydraulic analysis of the watershed and its tributaries, identification of management problems as well as alternatives for addressing flooding, bank instability, habitat protection and enhancement. A preferred project is also presented. Volume II consists of a stream management and maintenance program. It identifies an approach to routine maintenance such as vegetation management, bank stabilization and sediment removal along with suggested Best Management Practices for these activities. Volume III is a drainage design manual for determining criteria for design of drainage channels, storm drain systems and storm water detention as well as other storm water facilities.

There are eight (8) watershed management goals for the watershed:

  • Flooding
  • Erosion
  • Water Quality
  • Biological Resources
  • Land Use
  • Social Values
  • Public Involvement & Education
  • Inter-Agency Coordination
