<br /> <br />The final grade will slope to the south and will discharge the surface <br />water into our drainage area. <br />Future Conditions(Easterly Section) <br /> <br />The new•mining~will depress this-area approximately 45 -f t. in places. <br />The final grade will slope to the south with opportunity to drain off of <br />the property by using the arroyas to the east. The last or lowest area <br />to be drained will be across the south property line and/or just north of <br />the southeast property corner. <br />r.,.,,-t ~~~ t.,., <br />Using contour maps submitted in the permit request Exhibit "F", we <br />find that mining operation will increase the surface ~•iater discharge in <br />excess of 25a which is objectionable to the City. <br />Besides the increased runoff characteristics caused by constant slope <br />grading and de-vegetating, we will experience additional runoff because <br />3 retention reservoirs and six contour ditch dikes have been removed which <br />previously held the runoff and/or diverted it to a water shed to the west <br />which used the runoff in irrigation ditches by Christian Brothers Ranch. <br />We believe sumps or retention ponds should be built to retain the <br />surface waters and allow only the original flow or better yet, retain the <br />water 100.°6 and allow dissipation by seepage or evaporation either of which <br />could be an advantage or asset to both Brocerick & Gibbons and the City. <br />The third party, Christian Brothers Ranch, might be concerned about losing <br />some of the surface water that they now use for irrigation. <br />-3- <br />
