9. Engaging the CommunityEngaging the Community
• Through IRP Implementation
– Annual stakeholder meetings
– Biannual newsletters
– Website
• By Continuing Partnerships for
Related Programs
– Recycled Water Advisory
Group (RWAG)
– Stormwater workshops
• Beyond 2020 IRP
– Keep involved in next 2040

– Allows outdoor watering 3 days
per week
– Overall city-wide water usage
down ~20% from ‘06-’07
 Water Efficiency Requirements Ordinance (2009):
– Requires installation of high efficiency plumbing
fixtures in all residential and commercial buildings

North Atwater
Creek Restoration
• For decades, polluted
water has collected in
stagnant pools at the
base of the creek before
being discharged into
the LA River
• After restoration, a trash
collection device at
the top of the park
captures polluted
runoff flowing from
40 acres of urban
neighborhoods

21.  IRP was a stepping stone to build stronger
partnerships
– Interdepartmental/Interagency collaboration is now
the norm for the City of L.A.
– Stakeholders & the community participate in
planning process for numerous programs
 IRP was the precursor to many green programs
– Green Streets & Green Alleys
– Recycled Water Master Planning
– Water Quality Compliance Master Planning
– And many others
