Curb Ramp Scoping

The ADA requires that when a project constructs a new pedestrian facility (e.g. a new sidewalk or ped-push button), resurfaces a portion of the street, or performs other alterations, the project must provide ADA Compliant curb ramps along the route as part of the project.

ADA Curb Ramps Frequently Asked Questions with Answers

What is CREEC and what is the ADA Ramp Squad (CREEC Squad)?

  • CREEC stands for the Civil Rights Education and Enforcement Center.  The City worked with CREEC and Linda Dardarian (Goldstein, Borgen, Dardarian & Ho) to obtain a Settlement Agreement for constructing or remediating 1500 curb ramps per year over the next twelve years (2019-2030), along with other ADA efforts, to make Portland a most accessible City.  The ADA Ramp Squad (formerly known as the CREEC Squad) is the group within PBOT that verifies that each ramp constructed or remediated meets requirements.

My project was scoped and funded years ago and did not include ADA Curb Ramp upgrades.  Are there opportunities for additional funding and design support?

  • The ADA requires that curb ramps be constructed and upgraded as part of the public improvement project (or paving effort).  For older projects that were not scoped to meet ADA requirements, the ADA Ramp Squad is available to provide guidance to ensure that the project is ADA compliant to the maximum extent feasible within the scope of the project and, in some cases, may be able to provide additional funding for adding more ADA ramps to the project.   For more information contact the PBOT ADA Ramp Squad at:

How may I request the ADA Ramp Squad to design a curb ramp, provide a curb ramp assessment for project scoping, and/or an ADA curb ramp inspection for a City project? 

  • Tag, complete and submit the form for the type of request. Expect a follow-up response within 5 business days from the ADA Ramp Squad.

  • How may a person request a curb ramp?
  • Go to the City’s main web page and tag the I Want To Request An ADA Curb Ramp Link at .   This will take you to the RBR (Ramps By Request) web page which provides an overview of the program, prioritization criteria and the ADA Curb Ramp Request Form. 

Whom may I contact for more information and assistance?

Or Contact an ADA Technical Advisor for assistance.


What if a ramp does not entirely reside in the legal crosswalk?

For a proposed ramp that does not entirely reside within a non-marked legal crosswalk, consultation and approval by the City Traffic Engineer (or delegate) is required. This element of the ramp must be noted on the ADA Curb Ramp Design Form (Item D), along with written justification/approval by the Traffic Engineer attached or otherwise incorporated into the Ramp Form, and the Form signed by an ADA Technical Advisor.

What are ADA variances and MEFs and how are they used?

Variances and MEFs are the approvals needed when a proposed design does not meet all the criteria given in the Curb Ramp Design Report.  Open the link below for a full explanation describing when a Variance is needed and when a MEF is needed and how to get them.  If you have any questions, just as a PBOT ADA Technical Advisor.
