RESOLUTION REQUESTING A VARIANCE FROM THE MINNESOTA DEPARTMENT OF TRANSPORTATION FOR THE RECONSTRUCTION OF THE KEENE CREEK BRIDGE ON THE SKYLINE DRIVE.

BY COUNCILOR STOVER:

WHEREAS, it is deemed necessary for the public conveyance and safety that Minnesota Bridge Number L6128 at Keene Creek and Skyline Parkway (City Job No. 9091MC99) be reconstructed; and

WHEREAS, this project will not be eligible for municipal state aid funds unless it is constructed to urban state aid standards for an urban street, 30 to 40 mph design speed, or unless a variance is granted; and

WHEREAS, practical limitations require that the horizontal and vertical alignment through the project segment be constructed using utilizing a shorter horizontal curve radius and a shorter sag vertical curve length than dictated by standards resulting in a 26 m.p.h. design speed in lieu of a 30 m.p.h. which requires a variance from the commissioner of transportation in accordance with Minnesota Rules Chapter 8820.3300.

NOW, THEREFORE, BE IT RESOLVED, that the city of Duluth requests the commissioner of transportation for a variance from Chapter 8820, whereby the urban state aid standards be reduced for this project allowing for a 166 foot, 6.43 percent algebraic grade difference vertical sag curve in lieu of the required 252 foot and allowing for a 160 foot radius horizontal curve in lieu of the required 230 foot.


STATEMENT OF PURPOSE: In order to proceed with a variance request under Minnesota Rules 8820.3300, a formal request in writing in the form of a city council resolution must be submitted to the commissioner before it will be considered or reviewed. The city will then forward the resolution along with the other documentation cited in the rules for consideration by an advisory committee on variances appointed by the commissioner of transportation. The bridge in question cannot be rebuilt without the variance and would have to be moved at tremendous expense.
