APPENDIX A-SUBDIVISION ORDINANCE 5-23 roads and that their continuity be planned for. The street arrangement must be such as to cause no unnecessary hardship to owners of adjoining property when they plat their own land and seek to provide for convenient access to it. Where, in the opinion of the planning commission it is desirable to provide for street access to adjoining property, proposed streets and underground utilities shall be extended by dedication to the boundary line of such property. Half streets along the boundary of land proposed for subdivision will not be permitted. Wherever possible, streets should intersect at right angles. In all hillside areas, streets running with contours shall be required to intersect at angles of not less than sixty (60) degrees, unless approved by the administrator upon recommendation of the city engineer. 5-21. Service drives. Whenever a proposed subdivision contains or is adjacent to any Category II or Category III Street as defined in subsections 5-23-A and C of this ordinance, it may be required that provision be made for a service drive or inter-parcel connector approximately parallel to such right-of-way at a distance suitable for an appropriate use of the land between such highway and the proposed subdivision. Such distances shall be determined with due consideration of the minimum distance required for ingress and egress to the main thoroughfare. The right-of-way of any major highway or street projected across any railroad, limited access highway or expressway shall be of adequate width to provide for the cuts or fill slope easements required for any separation of grades. 5-22. Approach angle. Major streets shall approach the major or minor streets at an angle of not less than eighty (80) degrees, unless the administrator, upon recommendation of the city engineer, shall approve a lesser angle of approach for reasons of contour, terrain or matching or existing patterns. 5-23. Minimum widths. The minimum width of proposed right-of-way/street widths shall be as follows: A. Category I-50-foot right-of-way, 36-foot street. B. Category II-60-foot right-of-way, 40-foot street. C. Category III-70-foot right-of-way, 48-foot street. D. Service Drive-25-foot right-of-way, 22-foot street. E. Alleys-15-foot right-of-way, 12-foot street. F. Variation in right-of-way and street widths may be allowed when recommended by the public works director and the planning commission and approved by city council. Supp. No. 61 1739
