DroughtMath is doing fantastic work analyzing LADWP’s Urban Water Management Plan. The slides are great. I love this sort of analysis, and read every post. This isn’t my bailiwick, but I have some vague thoughts on the management plan process.
- DWR does not “vet” UWMPs for accuracy, because that would require the sort of work that DroughtMath is doing. To my knowledge, DWR checks the plans for completeness, not accuracy.
- NRDC’s suit is very appropriate.
- I have no reason to think LADWP’s UWMP is an outlier. I don’t know firsthand, but suspect most UWMPs are equally aspirational.
- Lois Henry’s column a couple weeks back is a beautiful example of the difficulty of getting solid answers to questions about water availability for development.
- Somehow, cities keep not running out of water. I don’t think that is because of the good work in their UWMPs. I attribute that to the surprising amount of slack we’ve had to work with, but that comes from a legacy of substantial water waste. Getting better (decoupling water use from population) is a good thing, but that starting point is nothing to be proud of.
