Public Works Committee 6. 2. <br />Meeting Date: 03/21/2017 <br />By: Bruce Westby, Engineering/Public <br />Works <br />Title: <br />Update on COR Wear Course Improvements <br />Purpose/Background: <br />Purpose: <br />The purpose of this case is to update the Public Works Committee on Staff's plans for completing wear course <br />improvements within The COR. <br />Background: <br />Several street exist within The COR that have only the bituminous base course and no wear course. These streets <br />include 146th Avenue between Center Street and Peridot Street, and Traprock Street between 146th Avenue and <br />Ramsey Parkway. The total estimated length of these street segments totals 2,110 linear feet. See attached figure. <br />The wear course was left off of these streets to allow development of the majority of adjacent parcels to be <br />completed first, thereby preventing damage to the wear course during build out. Unfortunately, this occurred right <br />before the great recession which caused development to stop. <br />Without the final lift of bituminous, the pavement structure is weaker than it was designed to be so continued use <br />without adding the wear course will only accelerate the end of life for the existing pavement. Staff therefore <br />proposes to add the necessary wear course improvements to the 2018 CIP for the segment of 146th Avenue between <br />Center Street and Peridot Street, and Traprock Street between 146th Avenue and Ramsey Parkway. The preliminary <br />estimated cost for this work is $60,000. No escrow funds are available to pay for this work so all costs must be <br />covered by the City. <br />Timeframe: <br />Staff estimates this case will take 5 minutes to present and respond to questions. <br />Observations/Alternatives: <br />NA <br />Funding Source: <br />This work is estimated to cost $60,000 and is proposed to be funded using PIR Funds, budgeted Street Maintenance <br />Funds, or a combination of the two. Staff will provide this recommendation when updating the CIP later this year. <br />Recommendation: <br />Staff recommends adding the necessary wear course improvements to the 2018 CIP for the segment of 146th <br />Avenue between Center Street and Peridot Street, and Traprock Street between 146th Avenue and Ramsey Parkway. <br />Action: <br />No action is needed on this item. <br />Attachments <br />
