Procedure on acceptance of public improvements. When the developer has constructed and installed the streets, drainage facilities, curbs, sidewalks, street signs, monuments and other improvements in accordance with City regulations, standards and specifications, and desires the City to accept the improvements, he shall, in writing, addressed to and in a form approved by the City Council, with copies thereof to the City Engineer, request the City Engineer to make a semi-final inspection of the improvements. If the improvements have been constructed under a performance guarantee after approval of a final plat, the developer shall submit an as-built plan showing as-built grades, profiles and sections and locations of all subsurface utilities such as french drains, combination drains, sanitary sewage disposal systems, both public and individual water lines, and control valves, gas lines, telephone conduits, monuments, iron property markers, and any other utility or improvements installed other than as shown on the approved final plat. Said as-built plan shall be certified to by a licensed New Jersey professional engineer. If any improvements are constructed prior to final plat approval, the final plat shall reflect all changes and as-built conditions and be so certified. Said as-built plan(s) shall be submitted on reproducible media.
