Water Conservation Ordinance:
– 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

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
