BE IT ORDAINED BY THE MAYOR AND COUNCIL OF THE CITY OF
GRAND ISLAND, NEBRASKA:
SECTION 1. Section 33-19 of the Grand Island City Code is hereby amended to
read as follows:
~33-19. Minimum Improvements
Inasmuch as the primary purpose of subdividing land is to create building sites, and inasmuch as vehicular
access and certain utilities are essential to urban development, it shall be the responsibility of the developer to install
in accordance with plans, specifications, and data approved by the public works director, certain required
improvements as follows:
(1) Staking: The following described monuments shall be installed before the public works director shall
approve the plat, or in lieu thereof, a performance bond in an amount equal to the cost of doing such work shall be
furnished to the City of Grand Island before the public works director shall certify to the council that the required
improvements have been satisfactorily arranged.
(a) The external boundaries, comers of blocks and lots, all points of curvature, and points of
tangency, shall be monumented by an iron rod or pipe not less than 1/2 inch outside diameter and
extending at least 24 inches below grade.
(2) Grading of Lots: When any building site is filled to a depth in excess of five feet, said fill shall be laid
down in six-inch layers, and each layer shall be given six passes with a sheepsfoot roller with optimum moisture
present for compaction to equal the bearing strength of the natural ground, indicated by Proctor test or other test
which may be approved by the public works director.
(3) Storm Drainage shall be conveyed to an approved storm drainage system if available and adequate to
accept the runoff from the fully developed subdivision. Available shall mean a system approved by the public works
director to serve the proposed subdivision. If an approved system is available but not of adequate capacity, then
provisions must be made for on-site detention to reduce the peak flow out of the subdivision to that which the
approved system can accommodate. The detention cell shall be sized to accommodate a ten-year design storm as per
criteria acceptable to the public works director. In computing cell capacity only the capacity above the elevation at
which approved positive drainage exists will be considered. Detention cells without approved positive drainage will
not be accepted. Determination of the approved form of positive drainage shall be made by the public works
director. Gravity drainage shall be used if possible. Provisions shall be made for surface water traversing the
subdivision. The subdivision agreement shall prohibit filling in of ditches or other drainage facilities and specify
ownership and maintenance responsibility of detention cells and other drainage features not dedicated to the public.
(4) Sanitary Sewer shall be provided to connect all lots in the subdivision in accordance with standard
specifications of the City of Grand Island to an approved public system if available and adequate to accept the flow
from the fully developed subdivision. Available shall mean an existing approved system or a system approved for
construction by the City. The city council may extend consideration of the preliminary study for up to 120 days to
consider a sanitary sewer extension approval. In no case shall the minimum diameter for residential developments be
less than eight inches, and for commercial and industrial developments the minimum shall be ten inches. If an
approved system is not available, then individual systems may be permissible on an initial basis, however, the
