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 />
