A portion of the cul-de-sac located on the south end of Junkite Street has had some undercutting of the existing concrete curb and gutter. This project proposes to remove and replace a portion of the concrete curb and gutter, perform a full -depth restoration of the compromised road section, and provide a stabilized erosion control mat in the boulevard area to prevent future erosion of the soils. Review of the storm sewer, sanitary sewer and watermain did not find issues requiring repair. The City will be placing inflow and infiltration (I/I) barriers on the sanitary sewer manholes with this project. The City received an MCES I/I Grant for this work, which will reimburse the City for the costs associated with the 1/1 barriers.

This ensures all bidders are bidding off the same set of plans, and all bidders are notified of any plan revisions (addenda) issued during the bidding process. Attached is the title sheet showing the scope of the improvements, as well as a plan sheet showing the typical sections, which includes information on the proposed pavement section. Plans are available upon request from the City Engineer. Timeframe: Staff estimates up to 10 minutes will be needed to present this case and respond to questions. Observations/Alternatives:
