Oregon Administrative Rules › Chapter 734 - DEPARTMENT OF TRANSPORTATION, HIGHWAY DIVISION › Division 51 - HIGHWAY APPROACHES, ACCESS CONTROL, SPACING STANDARDS AND MEDIANS › Section 734-051-4020 - Standards and Criteria for Approval of Private Approaches

Current through Register Vol. 63, No. 7, July 1, 2024
(1) Applicability.
			 This rule describes standards and criteria that the department applies to the
			 review of an Application for State Highway Approach that has been deemed
			 complete as set forth in OAR 734-051-3030. Applications submitted for change of
			 use of an approach may be reviewed under the standards and criteria set forth
			 in OAR 734-051-3020  in lieu of this rule.
(2) General Approval Criteria. Except for
			 applications where the department identifies safety or operations concerns set
			 forth in section (3), and except for applications that are subject to alternate
			 access considerations as set forth in sections (5) through (7), the Region
			 Manager shall approve an Application for State Highway Approach that meets the
			 general approval criteria (a)-(c) in this section. Additional criteria set
			 forth in section (9) apply to interchange areas.
(a) Approach Spacing Standards. Section (8)
			 of this rule sets forth the approach spacing standards, except that the spacing
			 standards applicable to interchanges and interchange areas are set forth in
			 section (9).
(b) Channelization
			 Standards. An application meets the channelization standards of this rule if
			 none of the conditions in (A) through (C), below, exist; where a condition in
			 (A) through (C) exists, an application may meet the channelization standards if
			 the existing or proposed lane configuration on the highway conforms to the
			 design requirements of the ODOT Highway Design Manual in effect at the time the
			 application is filed.
(A) Average daily trips
			 for the existing or proposed development exceed four hundred (400) for an
			 application on a two-lane highway with annual average daily traffic of five
			 thousand (5,000) or more motor vehicles; or
(B) Average daily trips for the existing or
			 proposed development exceed four hundred (400) for an application on a
			 four-lane highway with annual average daily traffic of ten thousand (10,000) or
			 more motor vehicles; or
(C)
			 Average daily trips for the existing or proposed development multiplied by the
			 annual average daily traffic on the highway is equal to or greater than the
			 products listed in the Table 1.
(c) Sight Distance Standards. Table 2 sets
			 forth the sight distance standards for approaches. An Application for State
			 Highway Approach meets the sight distance standard of this rule if the
			 intersection sight distance at the intersection of the proposed approach and
			 highway is equal to or greater than shown in Table 2. Intersection sight
			 distance shall never be less than stopping sight distance, as calculated in
			 accordance with 2011 AASHTO Policy on Geometric Design of Highways and Streets.
			 Sight distance must be unobstructed within the sight triangle based on the
			 following positions of measurement:
(A)
			 Driver's eye height equal to 3.5 feet above the road surface of the proposed
			 approach at a location 15 feet from the edge of the travel lane; and
(B) Object height equal to 3.5 feet above the
			 road surface at the near edge of the travel lane to the left and at the far
			 edge of the travel lane to the right of the approach. [Table not included. See
			 ED. NOTE.]
