<br />I". . <br />.. CITY OF ARDEN HILLS <br />. MEMJRANDtJM <br />. DATE: January 6, 1995 <br /> TO: Mayor and Council <br />. FRCM: Dan Winkel., Public Works SUperintendent /J. tjJ. <br />. SUBJECT : Request by the Anny National Guard Reserve to COImeCt to <br /> Arden Hills sanitary sewer and water systems <br />. Staff has received a request fran the Army National Guard Reserve for <br /> permission to connect to the Arden Hills sanitary sewer and water <br />. systems. The pro[X)sed connections are in the area of Hamline Ave. and <br /> Highway 96. During this past week staff has also received a revised <br /> set of pro[X)sed plans and specifications that are currently under <br />. review. <br />.. Staff has identified a number of issues that need further review prior <br /> to a final re[X)rt to Council. The issues are as follows: <br /> . Staff is discussing a connection agreement with City Atto:rney <br />. Filla that will be presented to the National Guard Reserve for <br /> approval. The agreement should include future ownership and <br />. rraintenance reS[X)nsibilities. <br /> . The pro[X)sed plans indicate that only one jacking would be done <br />. under Highway 96, and that l::oth the sewer and water pipes be <br /> installed in one 30 inch casing. Staff proposes that two <br /> jackings be done, one each for sewer and water. <br />. . The current pro[X)sal shows a 10 inch water main extended to the <br /> National Guard facility. Staff reccmnends that a 12 inch water <br />. rrain be used. This will naximize the amount of available water <br /> to the site. <br />. . The proposal also has two options for the sanitary sewer <br /> connection. The National Guard prefers option "A" which would <br />. require the sewage to flow into a City lift station in the Karth <br /> Lake area. Staff prefers Option "B" that empties the sewage <br /> directly into a gravity flow ID3I1hole, and will not need <br />.. additional pumping. <br />. <br />
