The Agreement required the Developer to deposit $148,951 with the City prior to building permit issuance, and to prepare design drawings for the intersection improvements prior to Certificate of Occupancy. The funds have been paid, and the plans and specifications were prepared by BKF Engineers and used for the bidding of this project. On September 25, 2017 the City Council rejected all bids for the project due to costs exceeding the total funding available for the entire intersection; bids sought at that time included constructing intersection improvements consistent with the conditions of approval, as well as additional improvements at the intersection of Marshall Street and Middlefield Road. The currently proposed agreement limits the scope of the improvements primarily to the intersection of Marshall Street and Jefferson Avenue given that this is the most critical location for improvements.
