3.03 Minimum Design Standards

3.03 Minimum Design Standards The design of the subdivision shall provide for efficient traffic flow, proper mixing of land uses, and a logical link between surrounding, existing development, and the proposed layout. The Comprehensive Land Use Plan should be used as a guide in determining if the design of the proposed subdivision is proper. The Planning Commission shall have the authority to deny a plat or request redesign, if, in its opinion, the layout is not the most suitable for the site. A. Blocks: 1. Length: Intersecting streets (which determine block length) shall be provided at such intervals as to serve cross traffic adequately and to meet existing streets in the neighborhood. In residential districts, where no existing plats are recorded, the blocks shall not exceed 1,320 feet in length, except that a greater length may be permitted where topography or other conditions justify a departure from this maximum. In blocks longer than 800 feet, pedestrian ways and/or casements through the block may be required near the center of the block. Such pedestrian ways or easements shall have a minimum width of ten feet. 2. Width: In residential development, the block width shall normally be sufficient to allow two tiers of lots of appropriate depth. In certain instances, however, a different arrangement may be required in order to provide better circulation or to protect a major circulation route. Blocks intended for business or industrial use shall be of such width and depth as may be considered most suitable for the prospective use. B. Streets and Alleys: The Planning Commission shall review all plats for impacts on the urban design, transportation, and utility functions of all rights of way, including any part of the system impacted by the subdivision. According to the policies and designs in the major street plan, or other plans and policies affecting rights-of-way, public realm design, and public facilities, the Planning Commission shall have the right to restrict and regulate the design and points of access to all property from the public streets system. Such restriction shall be indicated on the final plat . 1. Relationship to Adjoining Street System: The arrangement of streets in new subdivisions shall provide for the continuation of the principal existing streets in adjoining additions (or their proper projection where adjoining property is not subdivided) insofar as they may be necessary for public requirements. The width of such streets in new subdivisions shall be not less than the minimum street widths established herein. Alleys, when required, and street arrangement must cause no hardship to owners of adjoining property when they plat their land and seek to provide for convenient access to it. Whenever there exists a dedicated or platted half street or alley adjacent to the tract to be subdivided, the other half of the street or alley shall be platted and dedicated as a public way. 2. Street Name: Streets that are obviously in alignment with other already existing and named streets shall bear the name of the existing streets. Street names should not be similar to already platted street names. All street names shall be assigned by the property owner subject to the final approval by the Planning Commission in their review of the plat. House numbers shall be assigned by the Director of Public Works.
