(Amended by Ordinance No. 180917, effective May 26, 2007.) Public streets and public alleys shall conform to the requirements of the City Engineer for elements, widths, intersection location, grades, curves, materials and construction. If necessary, construction and slope easements may be required.
Public Streets shall be laid out to intersect at angles as near to right angles as practical except where topography requires a lesser angle, but in no case shall be less than 80 degrees unless the City Engineer has approved a special intersection design.
As far as is practical, public streets other than minor streets shall be in alignment with existing streets by continuation of the center lines thereof. Staggered street alignment resulting in "T" intersections shall, wherever practical, leave a minimum distance of 200 feet between the center lines of streets having approximately the same direction.
Intersecting public alleys shall be avoided, and sharp changes in alley alignment shall be avoided, but where necessary, the corners shall be widened sufficiently to permit safe vehicular movement. Dead-end public alleys shall be avoided, but where unavoidable, turnaround facilities as determined by Portland Fire & Rescue and the City Engineer shall be provided.Where a private street or private alley accesses the public right-of-way, the location and width of the access shall conform to 17.28.110 Driveways – Permits and Conditions.
Land divisions shall provide for the continuation or appropriate projection of existing arterial or collector streets in the surrounding area unless otherwise approved by the City Engineer.
