OFCNotes:
•For reference, the minimum clear widths required for fire apparatus access roads (fire lanes) under the Oregon Fire Code (OFC) may take precedence in some situations (20' fire lane width required where there are no fire hydrants, 26' fire lane width required for streets with fire hydrants, OFC 503 & OFC App. D).
•Fire lanes up to 26 feet wide shall have fire-lane/no-parking signs posted on both sides, while fire lanes wider than 26 feet (but less than 32 feet) shall be posted on one side (OFC D103.6.1&2).
•The OFC requirements cannot be modified solely by a land use approval.

Note: If a land use variance is granted for parking one side only, one curb to be painted and signed for no parking at time of street construction.
b. The number of travel lanes for arterial and major collector roads shall be determined by the volume of traffic. The City may require additional turning lanes where required by the City Engineer
c. Additional pavement and right-of-way width may be required to accommodate turning lanes, parking and bike lanes.
