Evaluate the budget for these programs annually.  Clarify and streamline public-facing information on incentive programs. Provide comprehensive and easy-to-understand forms for participating.  Expand training programs and resources for landscapers, including sample landscape plans and information on native plants.  Expand outreach to existing developments near the reclaimed system to promote connection.  Complete an ongoing evaluation of the Service Extension Request process and recommend improvements to the process. Land Conservation Strategies 14  Goal is to protect drinking water quantity and quality  Potential strategies include fee- simple acquisition, conservation easements, direct payments to landowners, and education and outreach  These strategies are in addition to, and work in concert with, the ongoing work of Austin Water’s Wildlands program Ch. 6 - Plan Implementation 15  Adaptive management approach  Approaches to mitigate inequitable impacts  Metrics to monitor implementation and the effectiveness of water strategies  Reporting, communication, and collaboration practices Adaptive Management Approach 16  AW will act in alignment with the five-year implementation actions included for each strategy  Strategy effectiveness will be monitored and evaluated at regular  Strategy evaluation will be publicly reported and will inform potential adjustments to specific strategies  The Water Forward plan will also continue to be updated on a five- intervals year cycle Approaches to mitigate inequitable impacts 17 Strategy Type Conservation Reuse Supply Approaches to Mitigate Inequitable Impacts Tailor program design and implementation of water budgets to avoid penalizing larger households and imposing inequitable burdens on marginalized communities Tailor program design, code development, and enforcement of landscape and irrigation requirements to avoid imposing inequitable burdens on marginalized communities Provide water conservation education, training programs, grants, and financial assistance to marginalized communities to help them keep their water use below water budget allowances and to minimize maintenance burdens Provide programs for maintenance support, training for building management, etc. for dual plumbed systems. Promote programs to assist customers in marginalized communities who are trying to navigate the permitting process in accessing education and assistance Continue to work with the Watershed Protection Department to allow centralized reclaimed water for outdoor irrigation across our community, by mitigating potential water quality impacts from reclaimed irrigation Continue to identify locations for onsite reuse or sewer mining to make reuse water available in areas of the City where centralized or decentralized reclaimed water is not available Continued implementation of the GoPurple program, including code exemptions for affordable housing and financial and development incentives Minimize rate impacts through Customer Assistance Programs Use low cost implementation project funding through Texas Water Development Board (TWDB) programs Address construction impacts on marginalized communities (traffic, noise, etc.) Explore options to minimize potential impacts to neighboring communities that may be impacted by strategies located outside of Austin Water’s service area For brackish groundwater desalination, develop effective brine handling methods that consider environmental impacts For Indirect Potable Reuse, evaluate and implement appropriate treatment processes for water discharged into Lady Bird Lake Partner with community organizations to provide education on water supply strategies and water quality • • • • • • • • • • • • • • • 18 Monitoring, Evaluation, and Adaptation Strategy Type Metric Adaptation Triggers Strategy yields meet targets based on actual population growth Annual strategy yield falls below target levels for two years in a row Strategy implementation progress Progress falls behind action timeline Conservation Reuse Strategy yields meet targets based on actual population growth Annual strategy yield falls below target levels for two years in a row Strategy implementation progress Progress falls behind action timeline Annual strategy yield Strategy implementation progress Annual strategy yield falls below target levels for two years in a row Progress falls behind action timeline Supply Historical annual demands compared to historical actual annual supply Demands increase beyond __% of supplies • • • • • • • • • • • • Possible Adaptation Actions Use smart meter data to enhance tailored customer outreach via My ATX Water portal Re-evaluate and enhance incentive programs Increase utility water loss control programs Re-evaluate staffing and funding levels for projects and programs Re-evaluate and enhance GoPurple incentive program Re-evaluate and enhance reclaimed marketing Identify reclaimed system projects that can be accelerated to improve system reliability and meet additional customer demand Re-evaluate staffing and funding levels for projects and programs Identify supply project delivery methods and tasks that can be accelerated Evaluate possible alternative supply project configurations or approaches Accelerate implementation of emergency supply strategies Re-evaluate staffing and funding levels for projects and programs Reporting, Communication, and Collaboration 19  Quarterly reports on implementation progress to Boards and Commissions  Public year-end annual reports including leading performance measures, descriptions of programmatic efforts, conservation performance, and total water use and loss. What’s Next 20  Further revisions to the draft Water Forward report • Editorial review, graphic design, etc. • Confirming plan alignment with WCP/DCP • Additional information on Colorado River Land Analysis plan development • Adding comparison of WF18 and WF24 strategies What’s Next?
