Refer to the following instructions before using this form:

Use one ADA Curb Ramp Design Exception form per intersection.

Use Form 734-5184 (ADA Curb Ramp Design Checklist) to aid in identifying when design exceptions are needed.

Review the design exception webpage before filling out this document. Take the online training course in Workday on how to fill out an ADA Curb Ramp Design Exception request form: ODOT – ADA - ADA Curb Ramp Design Exception Request Form 734-5112 User Guide (Jan 2023)

For training on ODOT ADA design and inspection practices see ADA Curb Ramp Inspector and Contractor Training. Course work Step 1 and Step 2 are recommended for designers.

Review Highway Design Manual Part 800, Part 900 and Part 1000 for design standards, practices, and procedures for curb ramp design and design exception preparation.

Illustration of Intersection:

Image should be clean, legible, and free from unnecessary line work. Include the entire intersection, identifying corner and ramp numbers, identifying street/highway names, north arrow, and highlight or circle the corner(s) with design exception(s).

Description of Exception:

[For each corner position, ramp position number, and design exception criteria, describe the difference between the requirement and level of accessibility achieved by the design.

Use ADA DE Description of Exception TemplateAP_ADDE_D_Exception_2023.07.20

For Example: “CR 2-1, Criteria B1: Requesting a ramp run slope of 9.2% for ramp run 3 which is above the ODOT design standard of 7.5% on all ramp runs.]

Description of Project:

[Describe the purpose, need and goals of the project. Be consistent with the General DE project description and business case.

Describe the project's scope of work with special detail to the following:

Will pavement surfacing be included?

What surface treatment is used?

What is the length of pavement surfacing work?

Will sidewalk be constructed? Where?

Will traffic signals replace pushbuttons, walk signals or controllers?

Is the project under construction contract?

For ADA Program projects only use ADA DE Description of Project Template: AP_ADDE_D_Project_2023.07.28 . This can be a helpful guide for other types of projects.]

Reasons for Not Attaining Standard:

[ADA requirements allow deviation from a requirement only when meeting that requirement is technically or structurally infeasible. For each corner position and design exception criteria explain in detail why the requirement cannot be achieved. Begin each DE request discussion with curb ramp number and criteria (for example CR 2-1, Criteria B1:).

Describe the site-specific constraints for each curb ramp where an exception is sought. Physical constraints may include underlying terrain, underground structures, adjacent developed facilities, drainage, or the presence of a notable natural or historic feature. Structurally infeasibility may occur when alteration to the structural element would degrade or affect the safety performance of the structure.

Explain why the constraint precludes achieving the ADA requirement. If it is possible meet the requirements; however, if not pursued describe why? Cost is not a justification for ADA non-compliance. Review Highway Design Manual Part 1004.4

Describe alternative designs considered in effort to meet the design standards. Describe why the proposed design was selected.]

Effects on Other Standards:

[Describe any considerations of how compliance with the ADA requirement might conflict with another federal, state, or local regulation or law. Regulatory conflicts could include preserving threatened or endangered species, the environment, archaeological or cultural or natural features, historic preservation, Oregon Drainage Law, Rail Safety requirements, etc.).

Are there tradeoffs with other engineering standards or best practices outlined in the design manuals, or other conflicting interests which are impacted due to meeting an ADA requirement (for example MUTCD, Structural loading requirements, hydraulics and other roadway geometric standards)?

Describe any feature that would be affected because of compliance with the ADA requirement. Begin each DE request discussion with curb ramp number and criteria (for example CR 2-1, Criteria B1:).]

Mitigation for Exception Included in Design:

[Curb ramp design is required to be accessible and usable by people with disabilities to the maximum extent feasible. Since at least one requirement is infeasible, explain the decision process to work around that loss in accessibility.

Specifically address:

What alternatives were explored to mitigate the non-standard attribute or design?

How does the current design achieve the maximum level of accessibility?

What site-specific mitigations are employed to ensure that people with disabilities can access and use the curb ramp system?

Begin each DE request discussion with curb ramp number and criteria (for example CR 2-1, Criteria B1:).]

Submitting Supporting Documents:

[Supporting photographs may be included in this word document file. Attach all other formats of supporting documents as an additional attachment or provide a link.

Supporting documentation should be clear and legible and show multiple alternatives that were considered before the submittal of this design exception.

Supporting documentation includes a detail sheet with elevations, slopes, and dimensions shown.

Existing site photos and construction details are necessary for analysis and review of design exceptions. Provide bridge or structural drawings when applicable

Provide the crosswalk closure approval letter where applicable.]
