Fontanari and Carey Water Rights and Irrigation Report <br />Torriorthents outcrop. The soils are comprised of 22.5% clay, 40.2% sand and 37.3% silt. Infiltration <br />rates range for moderately high to high at 0.20 to 2.0 inches per hour with the Torriorthents having very <br />low infiltration. The soils are listed in hydrologic soil groups B, C and D. <br />Additionally ten soil samples, under the direction of Doug Dean from the CSU Tri River Area Extension <br />Office, were collected from each of the three areas identified above. The three composite samples have <br />been sent to a soils laboratory for analyzes and the testing results are pending. <br />Irrigation & Piping System <br />On December 16, 1988, Ute Water Conservancy District entered into an agreement with Powder <br />Mountain Ranch, predecessor to Mr. Fontanari, to pipe the Martin Crawford Ditch and allow all four <br />priorities to be conveyed in the pipeline. The agreement provided a nonexclusive right for Mr. Fontanari <br />to divert his water rights, up to 5.3 cfs, from Rapid Creek at the diversion structure of the pipeline and to <br />divert its water at any time that it is able to divert water from Rapid Creek in priority. The agreement <br />also provided for three irrigation connections for Mr. Fontanari to divert its water from the pipeline. <br />The irrigation connection located directly adjacent to the Ute Water Conservancy District filter plant was <br />selected as the diversion point to provide a pressurize system for sprinkler and micro -spray irrigation on <br />Fontanari and Carey lands. Based on USGS mapping, at this point there is an estimated 69 pounds per <br />square inch (psi) of pressure available after accounting for friction flow losses. <br />Both a 12" diameter steel pipe and a 12" diameter DR -11 High Density Polyethylene (HDPE) have the <br />hydraulic characteristics to convey 5.3 cfs of water 2200 linear feet to the Fontanari/Casey lands and <br />provide a working pressure of approximately 45 psi to operate the sprinkler and micro -spray systems. <br />Steel pipe is recommended for this location as the soils are rocky and subject to movement. <br />Preliminary micro -spray and sprinkler cost estimates were obtained from the NRCS's 2016 Colorado <br />Environmental Quality Incentive Program Payment schedule and local suppliers. The micro -spray system <br />is assumed to have buried distribution piping. The sprinkler system cost estimate is based on "solid sets" <br />which consist of metal piping placed on the surface of the ground with sprinkler heads placed at <br />predetermined spacings. <br />Estimated installation and materials system costs along with piping costs are provide in Table 2. A <br />complete engineered design will be necessary to detail system components and verify the estimates <br />presented. <br />Fox Engineering Solutions, Inc. October 2016 Page 6 <br />
