Design Assumptions <br /> e slope of some Pipes was altered from the existing system in order to either increase their capacity, or maximize <br /> top cover ~'aP~. ltvvas assumed that lowering the inverts would not create problems for laterals which connect to the <br /> maid plpr system. <br /> segment AMUP060A and a portion of pipe segment AMUP0606 are still surcharged due to high water levels in the <br /> <br /> ~ azon main channel. <br /> e design capacities of the new pipes are as follows: <br /> UP060A: 72" CSP, 64 LF, design capacity =347 cfs <br /> UPO608: 72" CSP, 623 LF, design capacity = 834 cis <br /> MUP060C: 66" CSP, 2580 LF, design capacty = 413 cfs <br /> UP130A: 66" CSP, 882 LF, design capacty = 384 cfs <br /> WNlamte: 48" CSP, 128 LF, design capacity =296 cis <br /> <br />
