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
