A. Block Length. Intersecting streets determining block lengths shall be provided at such intervals as to serve cross traffic adequately and to meet existing streets and customary subdivision practice in the immediate area. Blocks shorter than 450 feet and longer than 1200 feet in residential districts should be avoided.
B. Block Width. The width of a block shall be sufficient to allow for two tiers of lots with utility easement, if required. Blocks intended for business or industrial use shall be of such width as may be best suited for the contemplated use of the property taking into consideration the probable arrangement of parking and truck loading and maneuvering upon the property.
C. Very Large Lots and Blocks. When a tract is subdivided into larger than normal lots or parcels, such lots or parcels should be so arranged as to permit the logical location and opening of future streets and appropriate resubdivision with provision for adequate utility connections for such resubdivision. Easements for the future openings and extension of such streets may, at the direction of the Planning Commission, be made a requirement of the plat.
A. Minimum Dimensions. The minimum width of lots shall be as required by the Zoning Chapter of the Grand Island City Code. Side lot lines should be at right angles to straight street lines and radial to curved street lines. Lots having a depth of less than 100 feet should be avoided. Lot sizes shall meet or exceed the requirement of the Zoning Chapter and should as near as practical meet or exceed the typical lot size for building sites in the immediate vicinity. Each lot shall be a buildable site after taking into account all yard spaces required by the Zoning Chapter. Excessive lot depth in relation to width should be avoided.
B. Corner Lots Wider. Corner lots in residential areas shall be of sufficient size to comply with the requirements of the Zoning Chapter.
C. Double Frontage. Lots with street frontage at both front and rear shall be avoided except when backing on a controlled access thoroughfare.
D. Street Frontage. Each lot shall have frontage (minimum width of twenty (20) feet) on a street that will allow for practical, physical vehicular ingress/egress, and allow for the proper provision of present or future municipal services to the lot.
E. Reversed Frontages and Key Lots. Reversed frontages at cross street intersections should be avoided except where it will match existing development. Key lots, being those inside lots fronting on side streets, should be avoided except where they are matching existing development and other lots are excessively deep. Key lots shall be prohibited where they disrupt utility or drainage easements. Reverse frontage and normal corner lots when adjacent to a key lot shall have additional width to allow front yard setbacks on both streets.
F. Septic Tanks. In subdivisions within city jurisdiction outside of corporate limits where buildings are to be served by septic tanks, the size of lots shall be sufficiently large to accommodate adequate drainage fields. Standards set forth by the appropriate County and State or other agencies shall be met.
G. Flag Lots. Flag lots, being those lots landlocked from public right-of-way except for a narrow tract of land of less width than minimum frontage as required by the Zoning Chapter should be discouraged except where development cannot reasonably be accomplished without their use. When such lots are platted, it shall be a requirement of the developer, builder, and owner to direct and maintain storm water drainage from the flag lot to the public right-of-way without directing the flow to adjoining property, i.e., drainage shall be by means of that strip of land connecting the area of the structure to the public right-of-way unless other drainage facilities are approved by the public works director.
(Amended by Ord. No. 8921, effective 7-28-2004)
A. Utility Easements. Unless otherwise required by the director of Planning, the director of utilities operations, or the public works director, utilities easements shall be 20 feet wide, falling half on adjoining lots along rear lot lines, and where necessary the same shall apply to side lot lines. The full width of an easement may fall on one lot. They shall be planned for easy and continuous access for maintenance, shall be continuous through the block and shall connect as nearly in line as possible with adjoining easements. To facilitate the use of easements, rear lot lines in curvilinear platting shall form straight lines for as long a distance as feasible. Direction changes shall fall so that a side lot line will intersect the point of change so as to allow the guywire easements to be located on lot lines.
B. Drainage Easements. Drainage easements for storm sewers or open channels shall be required where storm drainage cannot be practically carried under streets or in the right-of-way. Open channel drainage easements shall be required where there is evidence that the natural drainage for a large area traverses the subdivision. Drainage easements shall be sufficient in width so that motorized equipment may be used in their maintenance.
Pedestrian ways may be required so as to allow cross access for pedestrians in very long blocks. In general, blocks of 800 feet or more in length may have a requirement for a pedestrian way near the center of the block and shall have a minimum width of six feet. Pedestrian ways shall have a sidewalk width of four feet and have a minimum 42 inch high chain link fence on both sides.
