Multimodal Design Deviation Request Form

This form shall be completed when deviations are requested from the minimum design standards related to multimodal facilities. The minimum design standards are typically found in Chapter IX of the TDOT Design Guidelines and TDOT’s Standard Drawings. Designing a multimodal facility/roadway is not a one-size-fits-all approach. It requires an analysis of various site conditions to determine appropriate treatments and solutions. Using standard design elements, criteria, and dimensions may not be possible in these contexts that are often in constrained right-of-way. Applying flexibility in the geometric design process is often justified.

Design Deviation request is justified based on guidance from the following:

Design Guidance Source	Design Guidance Met?
Yes	No	N/A	Don’t Know	Source Reference if answered “Yes” (page, section, drawing, etc.)
AASHTO
PROWAG1
NACTO
FHWA
NCHRP
TDOT Design Guidelines (Section IX)
TDOT Standard Drawings
Guidance from other states

1. Proposed Right-of-Way Accessibility Guidelines, i.e. United States Access Board’s Proposed Guidelines for Pedestrian Facilities in the Public Right-of-Way.

In the space provided, please provide an explanation of the requested design deviation and describe other nationally recognized guidance that is met and that the design is based upon. Attach documentation of the specific design guidance met.

In the space provided, considering the safety and capacity of the facility, describe why the recommended deviation is the best design solution given the conditions, constraints, and particulars of this situation.

Local Program Projects require an acceptance letter from the highest city official or city engineer. The letter shall be attached to this request form.
