Prior to the adoption of 15847 on 01/04/1999, Section 25-42 read as follows.

    Streets and curbs and gutters shall be improved to comply with the standards contained herein, and in the city street and storm sewer specifications and design standards, and all design standards and specifications now or hereafter promulgated by the director of public works or adopted by the council, in accordance with the final construction plans required to be approved prior to final plat approval.

    (1)     Responsibility for improvements costs. It is the policy of the city to participate in or contribute only to certain additional costs of construction of major thoroughfares over and above the normal costs of local standard streets, when streets are designated at higher standards by the city. Such participation, and its timing, is not mandated and is solely at the election of the council, according to the needs of the community.

    (2)     Arrangement. All thoroughfares shall be located properly with respect to extending existing and platted streets, to special traffic generators, to population densities, and to the pattern of existing and proposed land uses.

        a.    Local streets shall be arranged so as to discourage use by through traffic, to permit efficient drainage and utility systems, and to require the minimum number of streets necessary to provide convenient and safe access to all properties. The use of curvilinear streets, cul-de-sacs, or U-shaped streets shall be encouraged where such use will result in a more desirable layout.

        b.    Where a subdivision abuts or contains an existing arterial street or highway having limited access, the commission may require the arrangement of residential lots with rear yards abutting the major street, or the provision of marginal access roads, or other such treatment as may be necessary in order to provide for adequate protection of residential properties, to afford separation of through and local traffic, and to provide for suitable access to the property involved.

        c.    When a new subdivision adjoins unplatted or undeveloped lands, the new streets shall be carried to the boundaries of such land as appropriate. A temporary turnaround approved by the director of public works shall be installed at this point, except when the terminus of the street is less than two hundred (200) feet from an intersecting right-of-way.

        d.    Private drives may be allowed only to provide internal circulation within a single lot or parcel.

    (3)     Blocks. Streets should generally intersect at intervals not exceeding one thousand (1,000) feet or less than four hundred (400) feet. Blocks shall have sufficient depth to provide for two (2) tiers of lots of appropriate depth. Exceptions to this prescribed block depth shall be encouraged in blocks adjacent to major streets, railroads or waterways.
