Benefits and Drawbacks of Allocations
Benefits
- Gives feedback on water use (as
a tool for better irrigation management)
- Could accompany a rate
structure
- Allows for individual decisions
- Provides certainty
Drawbacks
- Administrative burden
- Fair amount of accuracy
checking (needs a year to ramp up)
Description: Using satellite imagery/meter data, use and track an annual allocation that ramps down over time.
SLIDE 35
Staff Recommendation
Staff recommends exploring allocation options with the goal of adopting an allocation by the end of the year. The allocation could be developed with feedback from the Advisory Committee, and would be used simply for feedback during 2021.
