Article 5: Development Standards Section 5.8. Access and Circulation 5.8.6. Vehicular Access and Circulation

2. Driveway Intersections

a. Limitation on Direct Driveway Access Along Thoroughfares Direct driveway access to a development’s principal origin or destination points (including individual lots in a subdivision) may be provided directly from a major or minor thoroughfare only if: (1) No alternative direct vehicular access from a lower-classified accessway (e.g., collector street, local street, alley, or driveway) is available or feasible to provide; (2) Only one two-way driveway, or one pair of one-way driveways, is allowed onto lots with 250 or less feet of lot frontage on the major or minor thoroughfare, and no more than one additional two-way driveway or pair of one-way driveways per additional 250 feet of frontage; or (3) The development(s) served by the driveway is expected to generate an average daily traffic (ADT) count of 1,000 trips or less, or the Planning Director determines that the origin or destination points accessed by the driveway will generate sufficiently low traffic volumes, and the adjacent major or minor thoroughfare has sufficiently low travel speeds and traffic volumes, to allow safe driveway access while preserving the safety and efficiency of travel on the thoroughfare. b. Limitation on Direct Driveway Access Along Other Roadways The following standards shall apply to vehicular access along a roadway other than a freeway or a major or minor thoroughfare. (1) For single-family detached, duplex, manufactured home dwellings, and pocket neighborhood developments, no more than two direct driveway access points are allowed. (2) For bungalow courts, no more than one driveway access point is allowed. (3) For single-family attached and multifamily dwellings, and for institutional, commercial, mixed-use, and industrial developments, the number of vehicular access points along a street shall be minimized as necessary to protect the function, safety, and efficiency of travel on the street and any associated bikeways and sidewalks. (4) Where a through lot or corner lot fronts on roadways of different classifications, direct driveway access to the lot shall be from the lower-classified fronting street, to the maximum extent practicable. c. Spacing of Driveway Intersections (1) Intersections of driveways along major or minor thoroughfares shall be spaced at least 250 feet from any street intersection, as measured between centerlines. (2) Intersections of driveways along major and minor thoroughfares shall be spaced at least 250 feet from any driveway intersection, as measured between centerlines. (3) Intersections of full access driveways open to signalization shall be spaced at least 1,000 feet apart, as measured between centerlines. (4) Intersections of driveways into major and neighborhood shopping centers shall be spaced at least 400 feet apart, as measured between centerlines. (5) Intersections of driveways along a collector street shall be spaced at least 100 feet from any street intersection, as measured between centerlines. (6) Intersections of driveways along a local street shall be spaced at least 40 feet from any street intersection, as measured from the point of tangency of the radius curvature of the intersecting street.
