Re:                 CIP Project:  Kasold, 15th to 23rd

Kasold Drive is a major arterial street carrying 18,655 vehicles per day in 2001.  The section between 15th Street and Clinton Parkway was originally constructed of 7” reinforced concrete in 1971.  It has been milled and overlaid at least three times since it was constructed.  The original construction did not include subgrade stabilization or subsurface drainage improvements.  The concrete pavement has severely deteriorated and the road exhibits many problems:  major potholes, rutting, raveling, and joint failure.  This road needs to be totally reconstructed with subgrade treatment, drainable base, underdrain system, and an improved storm sewer system.  The total estimated construction cost to replace this road is $2.5 million. 

 

This project could be completed in two phases.  In 2005 reconstruct the road from the water tower to Clinton Parkway (south phase), and in 2006 reconstruct the portion from the water tower to 15th (north phase).  Phasing of the construction would not realize some economies of scale in items such as mobilization, reductions in unit prices for quantity, and traffic control. 

 

The engineering design needs to proceed this year with construction beginning next year.  It would be desirable and cost efficient to complete the design over the entire length of the project.  The estimated engineering costs for the design of Kasold from 15th Street to Clinton Parkway is $250,000.

 

Fiscal Note:  Based on a $2.5 million project the mill levy impact would range from 0.35787 in 2005 to 0.21009 in 2016 (attached).  If the project were bid in phases, assuming $1.5 million for each phase, the mill levy impact would range from 0.21613 in 2005 to 0.12863 in 2016 (attached). 

 

Action Requested:  Authorize staff to proceed with consultant selection for Kasold from 15th Street to 23rd Street.

 

Respectfully submitted,

Charles F. Soules, P.E.
