1 Water 2120: Securing Our Water Future URBAN LAND INSTITUTE WATER AS DESTINY SERIES MARCH 29, 2017

2 Water Resource Planning Leading the West 100-year Water Planning Horizon usually 40-years Aquifer is rising in the MRG and will continue for about another decade Groundwater management plan first of its kind in the west Aquifer Storage and Recovery Program is ongoing and key to future Water use in 2016 same as1983 (increase in 290,000 people)

3 Water Resource Planning Leading the West Watershed Restoration Recognized Nationally for Water Conservation and Education Efforts Significant Public Involvement public meeting, community conversations and Town Hall Incredible Stakeholder Support Incorporated climate change and the use of the best available science

7 ASR is Being Implemented Injection Well Design Bear Canyon is operational, using North I-25 non-potable water (600 ac-ft in 2016/17) Large Scale ASR permits obtained, construction in 2017/18

8 Water Usage is Decreasing Even as the System has Grown

9 Watershed Restoration Watershed management is an insurance policy for the surfacewater source of supply. Water Authority committed to spend $ 200,000 per year for five years
