(A) Circulation.
(1) The street pattern shall provide ease of circulation within the subdivision as well as convenient access to adjoining streets or unsubdivided land, as may be required by the City Engineer.
(2) Local residential streets should be so planned as to discourage their use by non-local traffic. Where a street will eventually be extended beyond the subdivision but is temporarily dead-ended, an interim turn-around may be required.
(B) Arterial streets. If a new subdivision involves frontage on an arterial street, as defined herein, the street layout should be planned to avoid, as far as possible, any private residential driveways from having direct access to such by providing access or frontal streets.
(C) Existing streets. Existing streets (constructed or recorded) in adjoining territory shall be continued at equal or greater width and in similar alignment by streets proposed in the subdivision, unless variations are approved by the City Engineer.
(D) Cul-de-sacs. Cul-de-sacs shall not be longer than 600 feet, unless necessitated by topography or other circumstances beyond the subdividers control.
(E) Half-streets. No half-streets will be accepted. Where there exists a dedicated or platted half-street adjacent to the tract to be subdivided, the other half, being a minimum width to meet this chapter, shall be platted.
(F) Stub streets. Where a subdivision adjoins unsubdivided land, stub streets shall be provided at locations as determined by the City Engineer to insure future access and traffic circulation.
(G) Intersections. All street intersections shall be at right angles. Where, because of topographic or other reasons, an intersection cannot be at right angles, such intersection shall be designed to insure safety.
(H) Easements. Easements for slopes and utilities shall be dedicated wherever necessary as required by the City Engineer. Easements shall be at least eight feet wide across the rear or front of all lots, except that a utility easement adjacent to unsubdivided lands shall be at least ten feet wide. In addition, easements may be required at other suitable locations by the City Engineer.
(I) Dimensional standards.
(1) Minimum width. The street right-of-way and roadway width shall not be less than the minimum width shown in the latest adoption of the City of Yuma Construction Standards Detail Drawings and the Transportation Element of the General Plan. Additional right-of-way or easements may be required for utilities, slope rights, drainage facilities or irrigation facilities.
(2) Alignment; minimum standards.
(a) One electronic copy of the complete, plans and profiles for street and alley improvements shall be submitted for approval of the City Engineer prior to approval of the final plat by City Council.
(b) Vertical curves:
1. Arterial streets: As determined by the City Engineer.
2. Collector, local streets: Minimum length 100 feet, except in cases approved by the City Engineer.
(c) Horizontal curves:
1. Arterials, access and frontal streets: 500 feet.
2. Collector streets: 200 feet.
3. Local streets: 100 feet.
4. Alleys: Laid out to provide turning radius at alley intersection.
(3) Reversed curve. Unless approved by the City Engineer, all streets shall have a tangent of 100 feet between reverse curves.
(4) Corners. At the intersection of two streets, property line corners shall be chamfered by a corner triangle in accordance with the currently adopted design and construction standards. The minimum corner triangle size shall be increased when the smallest angle of intersection is less than 90 degrees, or in any case where the City Engineer considers an increase necessary.
