STATE OF MINNESOTA COUNTY OF RAMSEY CITY OF ARDEN HILLS RESOLUTION NO. 83-25 RESOLUTION AUTHORIZING SANITARY SEWER CONNECTION TO THE NEW BRIGHTON SANITARY SEWER SYSTEM WHEREAS, the trunk sanitary sewer system of the City of Arden Hills (the "City") between Interstate Highway No. 694 and the south corporate limits of the City (i.e., District W) has been determined in the Arden Hills Comprehensive Sewer Policy Plan ("CSPP") to be inadequate, and WHEREAS, such inadequacy in that portion of the City's trunk sanitary sewer system which runs through District W is because of sewage flows from District NC as indicated in the CSPP, and WHEREAS, sewage flows from District NC are pumped three (3) times in the City before reaching the Metropolitan inter- ceptor in Roseville, and WHEREAS, the developable area of District NC is approxi- mately 1,100 acres, the ultimate average daily flow through District NC is estimated to be 0.793 M.G.D. (i.e., 793,000 gallons per day), and the estimated peak flow is 4.1 cubic feet per second, (based on a 3.3 peak flow,factor), and WHEREAS, the projected flows from District NC are as follows: Population .!.!.!.!: Equivalent Average Flow M.G.D.
