Title:
Update on COR Wear Course Improvements
Purpose/Background:
Purpose:
The purpose of this case is to update the Public Works Committee on Staff’s plans for completing wear course improvements within The COR.
Background:
Several street exist within The COR that have only the bituminous base course and no wear course. These streets include 146th Avenue between Center Street and Peridot Street, and Traprock Street between 146th Avenue and Ramsey Parkway. The total estimated length of these street segments totals 2,110 linear feet. See attached figure.
The wear course was left off of these streets to allow development of the majority of adjacent parcels to be completed first, thereby preventing damage to the wear course during build out. Unfortunately, this occurred right before the great recession which caused development to stop.
Without the final lift of bituminous, the pavement structure is weaker than it was designed to be so continued use without adding the wear course will only accelerate the end of life for the existing pavement. Staff therefore proposes to add the necessary wear course improvements to the 2018 CIP for the segment of 146th Avenue between Center Street and Peridot Street, and Traprock Street between 146th Avenue and Ramsey Parkway. The preliminary estimated cost for this work is $60,000. No escrow funds are available to pay for this work so all costs must be covered by the City.
