Each side of a platted property shall adjoin either a public right-of-way or easement in order to facilitate the connection of utilities to each lot. Where right-of-ways do not exist, easements must be dedicated as specified in the zoning ordinance. If necessary for the extension of water or sewer mains, storm drainage or other utilities, easements of greater width may be required along lot lines or across lots. In all cases, easements shall connect with easements already established in adjoining property.
