Ask which water source will be used, how much is expected annually and at peak, what cooling technology is proposed, whether reclaimed water is available, and what happens during drought restrictions.
Request answers in writing and ask that any operational commitments appear in the approval record.
Meeting question list
Use original public records whenever possible. A developer statement can explain an intent; an approval, permit, or utility filing is where enforceable details are more likely to appear.
Documents to request
Record the date, document title, agency, page number, and project address. That turns a claim into something another reader can check.
