Sec. 23-46. Same--Within city jurisdiction outside of corporate limits.
In accordance with urban development policy of the City of Norfolk, it shall be the responsibility of developers to install, in conformity with plans, specifications and data approved by the city engineer, certain required improvements as follows:
(a) Street improvements. Paving, including curbs and gutters, shall be completed in all streets in accordance with city standards and in conformance with any official street plan which may be adopted by the city council of Norfolk. Minimum roadway surface shall be constructed of six (6) inch portland cement concrete or asphaltic concrete equivalent. Curb and gutter shall be of portland cement concrete. Minimum width of the paved surface shall be thirty-one (31) feet back-to-back of curb. Developers may request construction to a minimum width of twenty-seven (27) feet, provided arrangements have been made to restrict parking to one side of the street.
EXCEPTION: Existing county roads adjacent to proposed subdivisions may be paved with a minimum of twenty-four (24) feet portland concrete or asphaltic concrete equivalent.
Requirements for paving, including curb and gutter, may be waived when all lots in the subdivision have a minimum frontage width of five hundred (500) feet or contain an area of more than five (5) acres, subject to recommendation by the planning commission and city council approval. Streets in such subdivisions shall have a crushed rock or gravel surface which meets city specifications.
(b) Staking. The external boundaries, corners of blocks and lots, all points of curvature and points of tangency shall be monumented by iron rods or pipes of not less than three-quarter-inch diameter, extending at least twenty-four (24) inches below grade.
(c) Grading. No grading or other construction shall take place within a street right-of-way until such plans are approved by the city engineer.
(d) Water supply. A water supply system may be provided to connect all lots in the subdivision to a public system, if available.
(e) Street name signs. Signs of the type in use throughout the city shall be supplied and installed by the developer.
(f) Sanitary sewer. Sanitary sewers shall be installed to adequately serve all lots in the subdivision, in accordance with standard specification of the City of Norfolk. In no case shall the minimum diameter be less than eight (8) inches. Where an approved sanitary system is accessible within three hundred (300) feet of the premises, the developer shall connect thereto. Where the city determines that an alternate point of discharge into the community system is more feasible for future community development, the developer shall be liable for that portion of the costs that would have been applicable if connection were made at the nearest point of the system.
Where an approved system is not reasonably accessible, individual sewage disposal systems may be utilized, in accordance with standard city specifications governing such installations.
(g) Sidewalks shall be constructed in accordance with section 23-42 of this Code.
(h) Storm drainage. The developer shall provide for adequate surface drainage, including installation of culverts, storm sewers, catch basins and other improvements to adequately handle storm water. Design shall be sufficient to accommodate a specified storm, as per criteria acceptable to the city engineer. First floor elevations shall be determined with regard to the one-hundred-year flood boundary.
(i) Other improvements. The installation of other improvements may be required where deemed necessary in the best interest of the community.
(j) Installation of improvements.
(1) Where a proposed subdivision is contiguous to the corporate limits, it shall be subject to annexation, and the developer shall utilize methods specified in Section A-10 [sic] to install minimum improvements.
(2) In any subdivision beyond the city limits, the developer shall install minimum required improvements. The city may require that the developer post a performance bond to cover the cost of the required minimum improvements.
(3) Forty-eight (48) hours’ notice shall be given to the city engineer prior to the start of construction on any improvements. The developer’s engineer shall provide the city with a signed certification assuring that improvements have been installed in accordance with the approved plans and specifications.
