Maurzd must be spiit into half pn account <br /> of short contour. Each half to be 10 x 32'to have the same amount of lateral length. Downslope sand bed is 16 feet. There are 15 <br /> inches of difference in elevation between the two rockbeds. Uneven elevation accounted for with duat pump,tirrae dose arrangement in <br /> the pump station. Foltowing hAound des9gn is per individual hatf urtit,(375gpd each)denoting exact dimensions,hole sizing,spacing and <br /> number. Each unit is identical in alt respects e�ccept for stope and rnerall footprint size. Stope is 8%for one unit and 13h far the other. <br /> i hereby certify that I have completed this work in accordante with all appticabte ordinances, rules and laws. <br /> Dale Denn 583 09/22/14 <br /> (Designer) (Signature) (License#) (Date) <br />
