The Department of Public Works (DPW) has updated Standard Details, Section VII, Roadway and Site Improvements, as follows:
- Replaced I-5 with I-5A, I-5B, and I-5C
- Removed I-14 through I-23
DPW has added new Standard Details, Section XII, Pedestrian Facilities, as follows:
DPW will also be advising Contractors during Procurement of this change to the Standard Details. All new solicitations for construction starting July 1, 2022 will include and be subject to the revised General Provisions. Attached are the replacement and new details.
These changes provide for enhanced accessibility by replacing outdated standard details with new standard details that meet the adopted 2010 ADA minimum requirements as well as look to the future by incorporating elements proposed in the Public Rights-ofWay Accessibility Guidelines (PROWAG) published by the U.S. Access Board in 2011. This update seeks to introduce widely accepted concepts, elements, and geometric requirements for curb ramp, sidewalk, and driveway apron construction including detectable warning surfaces, level landing areas, sidewalk passing zones, and running and cross slope requirements as well as provide guidance for both new and retrofit construction activities.
DPW has added this to the forthcoming design manual update. This memo serves as a notice to expedite the implementation of these new standard details. DPW will also be advising contractors of this change in requirements during contract procurement. All existing and approved Public Works Agreements for which construction of these facilities had not occurred prior to the above date shall be required to adhere to these new standard details.
