Ramsey, MN 55303 Proposed Grade Change at C.S.A.[~. No. 5 and Azurite Street N.W. Dear Council Members: As requested at your January 22, 1985 council meeting, we have reviewed the grade problem at C.S.A.H. No. 5 and Azurite Street N.W. A survey of the Azurite Street N.W. centerline showed that the first 45 feet starting at the edge of the northbound lane of C.S.A.H. No. 5 had a grade of 3.72%. The following 25 feet had a grade of 10.4%. Generally, it is desirable to limit the grade of the first 50 feet on a side street adjacent to a major highway to 2.0%. Also, the shoulder grade should slope away from the traveled lane instead of towards the traveled lane as currently exists at Azurite Street N.W. To improve the grade problem at C.S.A.H. No. 5 and Azurite Street N.W., we would recommend sloping the shoulder away from the traveled lane and limiting the grade for the first 50 feet to 2.0%. We would also propose continuing for the next 100 feet at a 5.0% grade. This change will require a cut of approximately 2.5 feet at the concrete driveway on the east side of Azurite Street N.W. In addition, the concrete driveway would have to be sloped back 53 feet from the edge of the street. The estimated cost of' the proposed change is $12,330, which includes 20% for overhead costs. We have contacted the Anoka County Highway Department and they indicated they would pay for the costs involved with the work within the County right-of-way. We have estimated those costs to be ~2,170. Therefore, the City's estimated share of the improvement ~~1 to $10,160. civil · municipal · planning · soils · land surveying
