A blank value cell means not disclosed by any source on file; a blank basis cell means the source gave the figure without saying on what basis.
The developer's figure is what the company said; what a permit allows is the ceiling a permit sets; measured means observed. Water is in gallons a day or a year, whichever the source stated; a tax claim given as a range shows both ends, each linked to the source that gave it.
Still not public, and where it would show up
The record adds each the day a source gives it. Why these documents.
- Water use A state water right filing or a water supply agreement.
- Who would use it A lease announcement or a tenant named in a filing.
- Power the campus would draw A utility or public service commission docket, an interconnection filing, or an air permit for an on site plant.
- Jobs and tax An incentive agreement, a county's economic development filing or a fiscal note.
