MS,; <br /> CONSULmGEIGlN'EERS June 20 1994 <br /> , <br /> File: 520-047-30 <br /> Mr. Dan Winkel <br /> City of Arden Hills <br /> 1450 West Highway 96 <br /> Arden Hills, MN 55112-5794 <br /> RE: AMBLE DRIVE STORM SEWER <br /> Cl..../i [NGINEEP:""G <br /> Dear Mr. Winkel: <br /> f'\'i',:;ON,'/EN!:': <br /> As requested at the public hearing for the 1994 Street Improvement project, we have <br /> N,~!NiC:Pt.i investigated the possibility of rerouting the Amble Drive storm sewer to divert the outlet <br /> away from Karth Lake. Our analysis of the existing storm sewer elevation has indicated it <br /> PiA,Vr-.,'iNG would be possible to divert the two low points on Amble Drive toward the intersection of <br /> Pleasant Drive and then extend storm sewer along Pleasant Drive to an existing manhole near <br /> _TRueTuRAl the intersection of Pleasant Circle. We have estimated that to accomplish this would involve <br /> over 1,000 additional feet of IS-inch pipe on Amble Drive plus approximately 900 linear feet <br /> SU~\lEYING of IS-inch pipe on Pleasant Drive. Of course, Pleasant Drive is not included in the street <br /> reconstruction program, so if this were to be undertaken without street reconstruction, it <br /> T~Amc would involve the restoration of at least half the existing street. Given this assumption, we <br /> have estimated the cost of this rerouting at approximately $70,000, including typical City <br /> TRA,'J$Po.~TATlON overhead costs. <br /> We have also done a cursory analysis of the total amount of tributary area to Karth Lake and <br /> the amount that is represented by the Amble Drive area, OUf review indicates that rerouting <br /> Amble Drive away from Karth Lake would remove a very small portion of the tributary area. <br /> It appears there is a large area from the south that outlets to Karth Lake and also a fairly <br /> large area east of Lexington that outlets to Karth Lake. <br /> Please let me know how you would like us to proceed on this issue. <br /> 1326 Energy pork Drive Sincerely, <br /> SI.
