Street Dedication: All streets in subdivisions in the City shall be dedicated to the City, except that private streets may be approved under special circumstances as determined by the Approval Authority. Except for width, walks and curbing designs specifically approved otherwise by the City Council as part of a special approval development, design and construction of all streets shall comply with Development, Design, and Construction Standards (also known as the City Standards) and be approved by the City Engineer. 2. Collector and Arterial Streets: Collector and arterial streets shall conform to the width designated on the Master Street Plan wherever a subdivision falls in an area for which a Master Street Plan has been adopted. For territory where such street plan has not been completed at the time the preliminary plat is submitted to the Planning Commission, collector and/or arterial streets shall be provided as required by the Planning Commission, with minimum right-of-way widths of sixty-six feet (66) feet for minor collector streets, seventy (70) feet for major collector streets, and eighty (80) feet for minor arterial streets. 3. Minor or Local Streets: Minor or local residential streets shall have a minimum width of sixty feet (60) feet. 4. Minor Terminal Streets (Cul-De-Sacs): a. Length. Minor terminal streets (cul-de-sacs) shall be not longer than 650 feet as measured from the center of the intersecting street to the center of the turnaround. Where topography or existing street geometry causes infeasibility of meeting this maximum distance, a variance request together with any proposed mitigation measures may be submitted to the DRC for review and possible recommendation to the Approval Authority. b. Turnaround Diameter. Each cul-de-sac must be terminated by a turnaround of not less than 120 feet in diameter of the right-of-way. If surface water drainage is into the turnaround, due to the grade of the street, necessary catch basins and drainage easements shall be provided. c. Cul-de-sacs shall not be allowed to be back-to-back or adjacent to each other (without an intervening street). In such circumstances, looping of streets or eliminating one of the cul-de-sacs is required. d. Temporary Dead-End. Except where a temporary dead-end is not greater than 150 feet, where a street is designed to remain only temporarily as a dead-end street, an adequate temporary turning area shall be provided at the dead end thereof to remain and be available for public use so long as the deadend condition exists. Such streets may only be allowed where reasonable opportunity for potential development exists, as determined by the city. Except in special circumstances, as determined by the city, no subdivision may be approved containing more than one (1) such dead end street (looping of streets would be required). 5. Access: For the safety and protection of citizens, permanent access shall be provided as follows: a. A cul-de-sac may serve a maximum of twenty (20) lots or units, not including the corner lots. b. A single permanent access may serve a maximum of thirty (30) residential lots or 100 multi-family units, not including corner lots located at the single access point. c. Two (2) permanent accesses may serve a maximum of 100 residential lots or 200 multi-family units, provided that the accesses are approved by the City Engineer and Fire Code Official and are designed to meet applicable fire apparatus access requirements, including but not limited to access road width, grade, turning radius, dead-end road limitations, hydrant access, emergency response circulation, and access separation. Additional access may be required where site conditions, project phasing, topography, traffic circulation, emergency response needs, or applicable fire code provisions warrant additional access. Access counts listed above are minimum subdivision access standards and shall not relieve the applicant from complying with applicable fire code, building code, public works, engineering, and emergency access requirements. d. Commercial and industrial subdivision access shall be evaluated on a case-by-case basis by the DRC. e. Special exceptions may be made by the DRC if justified by topography, hazards, or other physical constraint(s). 6. Marginal Access Streets: Marginal access streets of not less than forty (40) feet in right-of-way width may parallel all limited access major streets, as required by the City Engineer and approved by the City Council. 7. Half Streets: Half streets proposed along a subdivision boundary or within any part of a subdivision are prohibited. 8. Standard Street Sections: All proposed streets, whether public or private, shall conform to the street cross section standards as found in the City Standards, unless otherwise approved by City Council via a development agreement or other means. 9. Street Grades: Minimum and maximum grades for all streets shall be as found in the City Standards. 10. Alleys: Alleys may be required in the rear of business lots but will not be accepted in residential blocks unless part of a PRUD or other Special Approval Development as determined by the Approval Authority. 11. Trails: Trail accesses and connections to existing and planned trails shall be considered in the subdivision design. 12. Protection strips: Where a subdivision street parallels contiguous property of other owners, the Approval Authority may approve the retention of a protection strip of not less than one (1) foot in width between the street and adjacent property, provided that an agreement with the city and approved by the city attorney has been made by the applicant, contracting to dedicate the one (1) foot or larger protection strip free of charge to the city for street purposes upon payment by the then owners of the contiguous property to the applicant of a consideration named in the agreement, such consideration to be equal to the fair cost of the street improvements properly chargeable to the contiguous property, plus the value of one-half (1/2) of the land in the street at the time of the agreement, together with interest at a fair rate from time of agreement until time of subdivision of such contiguous property. Said agreement shall not be valid for longer than twenty (20) years. 13. Public Utility Easements. Public utility easements parallel to street rights-ofway of not less than ten (10) feet in width shall be dedicated to the City. 14.Natural Drainage, Municipal Utility, and Other Easements: The City may require easements for drainage from or through adjoining property be provided by the Applicant for any natural or historical drainage area and may allow or require piping and other improvements to protect adjoining property and/or water rights. Municipal Utility Easements of not less than twenty (20) feet in width shall be provided in the subdivision where required by the City for culinary water, sewers, and storm drainage . Other easements may be required by other utility providers. (Ord.2026-10, dated 5/12/26; prior codes: Ord.2022-8, dated 3/8/22 and Ord.2008-5, dated 4/8/08)
