IMPROVEMENTS TO STREETS ABUTTING DEVELOPMENT. (Cr. Ord. #37-02) The developer of any land division, that requires the execution of a development agreement, and abuts an existing Village street which has been constructed to rural standards shall, in conjunction with such development, improve the abutting street to urban standards from the centerline to the abutting land division's property line. The improvements shall include undercutting as necessary, asphalt resurfacing, construction of curb/gutter, installation of sidewalk and terrace landscaping. Taking into consideration concurrent and likely future development for the area in which the land division is occurring, and the infrastructure necessary to support such development, the Village, in its discretion, may require deferral of such work, and instead require the Developer to escrow an amount sufficient to defray the cost of the design and construction of such street improvements, and the curb/gutter and sidewalk at such future time as it is deemed appropriate by the Village.
