Development
• Emphasized spending down available balances. This has been a priority the last two years.
• Worked closely with Infrastructure staff on deliverability. Combed through the potential projects several times to verify spending ability. • Over the last several years, Hetch Hetchy Water has been working on a project prioritization methodology emphasizing likelihood and consequences of failure of any given asset.
• This year it was ready for use and made the prioritization process straightforward.
