106-2-1.010 Street Configuration Generally

A subdivision shall be designed to follow the street configuration requirements herein and elsewhere in this Land Use Code. Where this code allows an applicant flexibility on street location or configuration, that flexibility shall not be construed to relieve the applicant from requirements of this section. 1. General street configuration and alignment. The configuration of streets in a new subdivision shall: 1. Ensure the continuation of existing streets that can logically and reasonably be connected along the same street alignment; 2. Provide for the continuation of new streets into adjoining undeveloped land; 3. Be designed to consider the block length specified in Section 106-2-3, as it relates to both the subject property and adjoining property; 4. Not avoid the requirements of this section by shifting the responsibility of providing a street onto landowners of adjacent undeveloped or underdeveloped parcels; and 5. Not create an unnecessary hardship to providing street connections on or to other parcels in the general area, as deemed appropriate by the Land Use Authority. 2. Master planned street. A street shown in an applicable general plan, small area plan, master streets plan, development agreement, or similar adopted planning document, shall be installed by the applicant in the general location depicted in the planning document. 3. Section line and quarter section line street. A street shall be installed by the applicant along the general alignment of a section line and quarter section line, in compliance with the following: 1. Minor deviations from section lines. The alignment of a section line or quarter section line street may be adjusted up to 400 feet so the applicant may gain lots on both sides of the street; provided that the radii of the curves are appropriate for the type of street, as determined by the City Engineer. The street shall realign at some point downstreet with the same section line or quarter section line, or a previously created street or dedicated street right- of-way intended to be or become the same section line or quarter section line street. 2. Alternative street alignment. The Land Use Authority may approve alternative street alignment only when the applicant demonstrates compliance with one or more of the following objective criteria: 1. The alignment reduces public costs for operations or maintenance of the street. 2. The alignment reduces conflict with other public infrastructure that cannot be mitigated with reasonable effort. 3. The alternative alignment reduces environmental disturbance that cannot be mitigated with reasonable effort. 4. The alternative alignment preserves existing agricultural operations or irrigation infrastructure. 5. The alternative alignment avoids slopes greater than 15 percent. 6. The alternative alignment maintains future connectivity opportunities. 3. Approval shall be based on written findings demonstrating compliance with these criteria. 4. Angle of intersecting streets. Any street approaching an arterial or collector street shall approach at an angle of not less than 80 degrees. 5. Half-street. A half-street shall be governed as follows: 1. Within a subdivision. A half-street is not allowed within a subdivision except as more specifically provided in this Land Use Code. 2. On a subdivision boundary. Where a subdivision's boundary shares a common line with undeveloped land, an approximate half-width street rightof-way is allowed as long as: 1. The required street improvements include half of what is otherwise typically required for the type of street plus at least a 20-foot wide vehicle travel surface, designed to specifications of the City Engineer; and 2. The street right-of-way within the bounds of the subdivision is wide enough to accommodate these street improvements.
