Table D.2 identifies <br />this cropping pattern as well as the net agricultural return. Lands <br />in the San Juan West Watershed were located within climatic zones A, <br />B, and C. <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 prelimina-ry 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 />an initial residual preliminary payment capacity requiring further <br /> <br /> <br />consideration. A total of 9 parcels covering 310 acres showed an <br /> <br /> <br />initial residual preliminary payment capacity. <br /> <br />An off-farm irrigation transmission system was designed for those <br /> <br /> <br />paccels near the San Juan River showing a residual preliminary <br /> <br />9 <br />
