Table D.2 identifies <br /> <br /> <br />this cropping pattern as well as the net agricultural return. <br /> <br />D.4.4 Preliminary PIA Analysis <br /> <br /> <br />A preliminary PIA analysis was performed comparing a parcel's <br /> <br /> <br />payment capacity with a preliminary estimate of the cost to pump <br /> <br /> <br />water from the river to the parcel. This preliminary water cost was <br /> <br /> <br />based on the static pumping lift (the difference in elevation from <br /> <br /> <br />the water surface in the river to the elevation of the parcel) for <br /> <br /> <br />gravity irrigated fields or plus a field delivery pressure of 60 psi <br /> <br /> <br />for sprinkler irrigation. Detailed tabulations of the analysis are <br /> <br /> <br />shown in Appendix D.l. Table D.3 identifies only those parcels with <br /> <br /> <br />a positive residual payment capacity requiring further <br /> <br /> <br />consideration. A total of 20 parcels covering 582 acres showed a <br /> <br /> <br />positive residual payment capacity. <br /> <br />An off-farm irrigation transmission system was designed for those <br /> <br /> <br />parcels near the San Juan River showing a positive residual payment <br /> <br /> <br />capacity. Those calculations are shown in Appendix D.2 and <br /> <br /> <br />summarized in Table D.4. Parcels with a positive payment capacity <br /> <br /> <br />after comparing the residual payment capacity to the cost of water <br /> <br /> <br />are initially identified as practicably irrigable. <br /> <br />9 <br />
