      \item{\emph{Note:} Regression results from equation \eqref{mainreg}. The Subd1 variable is an indicator for a parcel being in the subdistrict. Surface and Ground variables are indicators for the respective water source being used to irrigate the parcel. The Structure Value variable is the reported USD value of additional structures and enhancements on the property. A number of variables are omitted from the table for clarity. The omitted variables include, all year fixed effects, an indicator for having a well on the parcel, indicators for  a parcel joining subdistrict 2, and a indicator that flags records with suspect reported area’s.}
