current 90-degree corner is a hazard for plowing. Review of the sanitary sewer and watermain did not find issues requiring repair. The City will be placing inflow and infiltration (1/1) barriers on the sanitary sewer manholes with this project. The City received an MCES 1/1 Grant for this work, which will reimburse the City for the costs associated with the I/I barriers. Televising of the storm sewer system found more issues than anticipated, and will require removal and replacement of six storm sewer structures and their connecting pipes. The majority of this work will be concentrated at the intersection of Sunwood Drive and Zuni Street. The current pavement marring layout meets State Aid standards, and the road is proposed to be marked back to the existing layout.

Staff does not anticipate significant comments from State Aid which would require moving the proposed project bid opening. Full plans are not attached to this case to prevent potential bidders from downloading plans attached to the case to prepare and submit their bids, rather than purchasing the plans through QuestCDN, the electronic bidding software used by the City of Ramsey. 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.
