17.20.010 Streets and bridges.
(1) Relation to Adjoining Street System. The subdivider shall locate streets within the subdivision so that the streets will connect with existing streets. If the adjoining land is zoned for residential use, streets shall be located so that the adjacent land may be most efficiently subdivided.
(2) Standards.
(a) Major and collector streets shall conform to the location and width designated on the transportation element of the general plan and the official map accompanying the element wherever a subdivision falls in an area for which such a plan has been adopted.
(b) The minimum right-of-way width of streets within a subdivision shall be based on the transportation master plan, the Riverton City Standards and Specifications Manual, and as approved by the planning commission.
(c) Minor terminal streets (cul-de-sacs) shall not be longer than 1,000 feet from the centerline of the adjoining street to the center of the cul-de-sac, or as determined by the city. Each cul-de-sac must be terminated by a turnaround of not less than 80 feet in diameter. If surface water drains into the turnaround, due to the grade of the street, necessary catch basins and drainage systems and easements shall be provided. Where a street is designed to remain only temporarily as a dead-end street, an adequate turning area shall be provided as follows:
(i) Where the street dead-ends into a subsequent phase of the same subdivision, a temporary paved 80-foot-diameter turnaround and a permanent easement of right-of-way on the property shall be required.
(d) Streets along a subdivision boundary shall be constructed to city standards, except that with the approval of the planning commission, the right-of-way line may be contiguous with the front of sidewalk.
(e) Partial street right-of-way width shall be considered only if full asphalt and curb and gutter improvements are installed on both sides of the road. The city may allow a partial right-of-way only when the above-described improvements are installed.
(f) All proposed streets, whether public or private, shall conform to the Riverton City Standard Specifications and Plans Manual. [Ord. 15-23 § 1 (Exh. A); Ord. 15-13 § 1 (Exh. A); Ord. 13-11 § 1 (Exh. A); Ord. 8-17-99-1 § 1 (Exh. A); Ord. 2-3-98-1 § 1 (Exh. A). Code 1997 § 12-325-040-A.]
17.20.020 Natural drainage and irrigation water.
(1) Standards.
(a) Natural Drainage and Other Easements. Public utility easements shall be provided on every lot, including a 10-foot easement on front and rear property lines, and a seven-and-one-half-foot easement on side property lines. Drainage easements may be required as determined by the city. Where natural drainage channels or wetlands controlled by the State Engineer and/or the U.S. Army Corps of Engineers cross a subdivision, the subdivider must obtain the necessary permits to modify such drainage facilities from the appropriate agencies.
(b) Irrigation Water. No gravity flow open irrigation ditches shall be permitted within the boundary of a subdivision or minor subdivision. All necessary irrigation ditches, whether used for the purpose of transporting irrigation or waste flow water, must be maintained within a subdivision or minor subdivision, and must be replaced with a pipe culvert. The developer of a subdivision must provide for the rights of all irrigation users, both upstream and downstream of the proposed development. Notification of and coordination with downstream water users in the area of the subdivision shall be the responsibility of the developer. [Ord. 15-23 § 1 (Exh. A); Ord. 8-17-99-1 § 1 (Exh. A); Ord. 2-3-98-1 § 1 (Exh. A). Code 1997 § 12-325-040-B.]

(1) Standards. In subdividing property, the planning commission shall give consideration to suitable sites for schools, parks, playgrounds, greenbelts, trails and other areas for similar public use as recommended by the city’s adopted general plan.
