(A) Unless otherwise stipulated by the city, all materials incorporated within and work performed in the construction of streets shall meet the requirements of the appropriate portions of the most recent versions of the State Highway Department Standard Specifications and/or Detail Specifications of the City’s Design Standards for road construction, whichever are more stringent. Sections not listed shall not relieve the subdivider from complying with standards of a recognized authority approved by the city.
(B) The subdivider shall be required to prove that materials supplied and items constructed meet these regulations. Certifications and test results shall verify such factors, including, but not limited to, asphalt grades, aggregate gradations, mix design, application rates and compaction percentages.
(C) The city has the right to require materials that will enhance economics and facilitate operations associated with long-term maintenance efforts. Materials that meet state and the above- referenced standards without having city approval for utilization within a particular street section might not be acceptable per se.
(D) In new subdivisions, the city will require maximum safety and efficiency of traffic flow by minimizing the number of automobile access points along arterials or collectors. Lots with private drives fronting on arterials or collectors are discouraged. In no case shall an access road in a newly platted subdivision be permitted which is closer than 300 feet from the intersection of two arterial streets, an arterial and a collector street or two collector streets.
(E) (1) Accompanying the preliminary plat, a road construction plan shall be submitted. It will be of similar size and format to the preliminary plat and shall be a reproducible drawing.
(2) It shall give the following information:
(a) Name and width of each street and associated right-of-way;
(b) Centerlines of street rights-of-way with dimensions between intersections, centerlines or tract boundary lines;
(c) Locations, dimensions and purposes of any easements;
(d) Longitudinal and transverse slopes;
(e) Typical sections, including width, thickness, material composition and compaction requirements of all courses;
(f) Material specifics, invert elevations, sizes, slopes and drainage channel requirements of all drainage structures;
(g) Identification, location and miscellaneous particulars of all utilities to be located within the rights-of-ways;
(h) Obstruction-clearing widths;
(i) Existing and proposed contours;
(j) Adequate curve data to allow construction as intended;
(k) Survey markers and ties; and
(l) Professional engineer stamp will be required on road plans.
(3) The review of the preliminary plat shall include a review of the road construction plan and related information.
(F) Preliminary acceptance is an initial approval of the roads by the city. It shall follow an official inspection and written report of findings by the City Engineer. Accompanying the subdivider’s written request for such an inspection shall be an updated version of the road construction plan. It shall contain a statement from the subdivider’s engineer that the information contained thereon is as constructed. Such inspection and report shall verify and certify that the dedicated roads have been constructed according to and meet design standards of these regulations.
(G) The subdivider shall maintain the accepted roads in good repair for a test wear period of 24 months from the date the roads pass preliminary acceptance. During such time, the city shall advise the subdivider to take those actions necessary to keep the roads in the same general condition that they were in for the preliminary inspection. If, in the opinion of the city, the subdivider does not adequately maintain the roads or if unusual or excessive reconstruction or maintenance obligations seem evident, the city reserves the right to extend the test wear period.
