I . . I CITY OF ARDEN HILLS MEMORANDUM " DATE: June 7, 1996 I TO: Brian Fritsinger, City Administrator y). FROM: Dwayne'Stafford, Public 'Yorks Superintendent I SUBJECT: Old Highway 10 Watermain Project I Backl!round The Arden Hills City Council has previously adopted a resolution ordering plans and I specifications for the Old Highway 10 watermain project. Since that time the City Engineer, Greg Stonehouse and Mr. Stafford from the Arden Hills Public Works Department have walked the proposed project site. It has been determined that the existing sanitary sewer main, lies I parallel to the edge of roadway approximately 86 to 10 feet west of the pavement edge. State standards call for a 10 foot horizontal separation between sanitary sewer lines and watermains. This leaves the City with no choice, but to install the watermain approximately 20 feet west of I the roadway edge, Under these circumstances special precautions must be made to protect large pine trees, on top of a steep bank for approximately 200 linear feet. Ie Protection, for these trees may necessitate the use of a trench box and could increase the job costs by approximately $5,000. Staff feels that moving the watermain further west may also increase I restoration costs in other areas, which may add an additional $5,000. Recommendation I The Public Works Staff recommends Council adopt Resolution 96-40, approving the plans and specifications and ordering the advertisement for bids in the matter of Old Highway 10 Watermain Improvement of 1996, Council would do this with the understanding that the I estimated cost of the project may increase by approximately $10,000. This would bring the total estimated cost of the Old Highway 10 Watermain Project to $101,300, I I I I f' I
