11-7-1 Layout Of Blocks And Streets

The design of blocks, streets, lots, open spaces and other design factors of the preliminary and final plats of subdivisions shall be in harmony with design standards recommended by the ALUA and other departments and agencies of the city government as is necessary. Design standards shall be approved by the city council and shall include provisions as follows, which are hereby approved by the city. All improvements shall be designed by a professional engineer licensed in the state. A. Length: Blocks shall not exceed nine hundred fifty feet (950') in length. Where existing conditions dictate, longer blocks may be approved by the city council as recommended by the ALUA. B. Width: Blocks shall be wide enough to adequately accommodate two (2) tiers of lots. Each lot shall abut on a street or lane shown on the subdivision plat or on an existing public street. Double frontage lots shall be prohibited except where unusual conditions make other designs undesirable as determined by the ALUA. C. Walkways: Dedicated walkways through a block may be required where access is necessary to a point designated by the ALUA. Such walkways shall be a minimum of six feet (6') in width but may be required to be wider where determined necessary by the ALUA. Where required and as approved by the city, the applicant shall surface the full width of the walkway with a concrete or asphalt surface, and install a chain-link fence, or its equal. Barriers at each walkway entrance shall be provided by the applicant to prevent the use of the walkway by any vehicle (motorized or nonmotorized) greater than three feet (3') in width. D. Business or Industrial Use: Blocks intended for business or industrial use shall be designated specifically for each purpose with adequate space set aside for off street parking and delivery facilities. E. Cluster Housing: Subdivisions containing multi-family dwellings or other types of cluster housing as allowed by the zoning ordinance shall provide adequate space for off street parking. (Refer to the zoning ordinance for parking requirements.) F. Design and Arrangement: Lot design and arrangement shall provide for satisfactory and desirable sites for buildings, be properly related to the topography and relate to or improve the character of surrounding developments. G. Zoning Requirements: All lots shown on the preliminary and final plats must conform to the minimum requirements of the zoning ordinance for the zone, or proposed zone, in which the subdivision is located, and to the minimum requirements of other agencies having jurisdiction. H. Side Lines: Side lines of lots shall be designed to approach street lines at approximately right angles. (Ord., 8-12-2003)
