Which document closes each gap

Tax abatements or other public subsidy: The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
Permanent jobs promised: The economic development application or incentive agreement, which usually states a job commitment and a clawback.
Land area: The rezoning application, the plat, or the deed recorded with the county.
How the community has received it: Planning commission and governing body minutes, public comment records, and any petition or lawsuit filed in the county.
