Due to the utilities,it was determined that this design could not be conducted <br /> without substancial relocation of the existing utilities. <br /> HKGi and Sunram proposed and alternate design redirecting the stormwater through the upper parking <br /> lot. Additionally,it was determined that the existing manhole and sump was undersized and highly <br /> degraded and required replacement in order to adequately meet the expected discharge of water from the <br /> alley and upper parking lot. This redesign included additional pipe,upgrading the existing manhole to a <br /> 60 inch sump and adding a skimmer device. <br /> The change order amount will be $13,315.00 that will be paid for from contingency and the stormwater <br /> fund. <br /> Financial Impact <br /> There is no impact to the city General Fund. <br /> Attachments <br /> ■ Change Order <br /> POWERED 6T <br /> AR <br />
