• Section 4.5.9.7: Curb Ramp Design Waiver – Add the additional language in Red to this section. see below:

Where infeasible to construct a pedestrian facility to ADA standards, a waiver form is required regardless of governing authority. Identified infeasible facilities shall be added to the ADA collector application and a waiver form completed by the district with information supplied by the governing authority. The final approval for a waiver, including waivers on local projects utilizing federal funds and permit projects on ODOT maintained roadways, rests with the District Design Engineer.

• Section 6.3.4: Bicycle Lanes – Switch the order of Items No. 4 and 5 under the sub-heading, “Bicycle Lanes Adjacent to On-Street Parking” to be as shown below in Red:

4. Provide shared lane markings in accordance with Section 6.3.1. This design is unlikely to accommodate the Interested but Concerned Bicyclist, but could accommodate the Highly Confident Bicyclist.
5. The minimum combined bicycle lane and parking lane width is 12 ft. All other travel lanes should be narrowed to the allowable constrained width before the minimum combined bicycle and parking lane width is considered. Pavement markings may be used within the bike lane to identify the potential door zone area by extending parking tees or diagonal pavement markings into the bike lane up to 3.5 ft. from the parking lane line. See Figure 6-7.
