On-track with previous (2012) recommendations resulting in a drop in SSOs/100 miles from 16 in 2002-2003 to just 7 in 2011-2012
• Low Priority Recommendations:• Capital Planning: Do a
better job of coordinating project planning between the C&M and Capital planning departments
• C&M: Develop a post-SSO water quality management plan
• FOG program: Identify major contributors and budget for education
• High Priority Recommendations:• Capacity Management:
prevent SSOs through proactive cleaning and focused preventative maintenance.
• SSO response: Record rainfall data to track wet weather SSOs
• Customer Service: Track information on the status of SSO serve requests
