Engineering Design and Review

Land development adjacent to RTD facilities or property is reviewed by RTD Engineering, which comprises several disciplines. These reviews ensure that planned development enhances the transit experience, safeguards public safety and access while not compromising RTD’s normal Park-n-Ride, bus, and train operations or maintenance.


Submittals are typically made through the local jurisdiction with a referral for RTD review.

Coordinate your work with the local Jurisdictions to submit your plans to RTD.

Please direct submittals to RTD that do not require jurisdictional review or RTD related land development questions to or call 303-299-2299.


Reviewers look at the following which includes, but is not limited to:

  • Compliance with RTD Commuter Rail, Light Rail, Bus Infrastructure Design Criteria and Guidelines.
  • Compliance with Americans with Disabilities Act Standards for Accessible Design (2010 ADASAD) or most recent adopted version and FRA guidance.

RTD Design Criteria

RTD has multiple criteria manuals. Please contact RTD Engineering if you are uncertain which apply to your work or project. More than one may apply.

RTD Criteria and Procedure Manuals

Among the many RTD criteria and requirements, RTD has specific concerns and procedures for some criteria, including but not limited to the design and construction of:

  • Drainage Structures: RTD looks at direct and indirect impacts to RTD ROW & facilities.
  • Fences & Security: RTD is concerned with both physical aspects and impacts to visible corridors and sight triangles.
  • Transit Oriented Development
  • Utility Design & Construction: In addition to the Engineering Design Review, RTD requires a separate design review process for Utility work.

If any part of your work violates RTD criteria requirements, you MUST apply to RTD for a Variance Request.
