Wetlands

The mission of the Wetland Program is to provide technical assistance for transportation project development and construction with the goal of an overall benefit to the aquatic ecosystems in Colorado.

Revised Programmatic Wetland Finding MOA and Template

CDOT and FHWA revised the Memorandum of Agreement between the two agencies regarding the programmatic approval of certain wetland findings. The most notable change to the wetland finding reporting process is the addition of a template that is required for the preparation of all programmatic wetland findings. The programmatic wetland finding shall be applied for all federal-aid transportation projects that meet all 8 criteria below: 

  1. The project is being prepared as a categorically-excluded minor project as defined in 23 C.F.R. 771.117.
  2. Project activities will involve at least 500 ft2 of permanent wetland impacts or 1,000 ft2 of combined temporary and permanent wetland impacts. Projects with wetland impacts less than above do not require a wetland finding.
  3. Less than one acre of wetland will be impacted either temporarily, permanently, or in a combination of the two.
  4. All practicable alternatives to avoid and minimize impacts have been addressed and documented in the wetland finding, as specified by Executive Order 11990 and the FHWA Technical Advisory T6640.8A .
  5. The wetland compensatory mitigation ratio is no less than l: I, regardless of jurisdictional status, unless the mitigation plan will replace functions with a lower mitigation ratio.
  6. No state or federally-threatened or endangered species will be affected by project activities.
  7. The project will not impact a Gold Medal Trout Stream, a designated National Wild and Scenic River, or other areas of special ecological concern (i.e. fen wetland, fish spawning ground, etc.).
  8. The project does not require a Clean Water Act section 404 permit, or the project is authorized under a section 404 nationwide permit.

When any of the above criteria cannot be met, the project does not fall into the category of a programmatic wetland finding. In this case CDOT or its representative will prepare a non-programmatic wetland finding that follows no template. The level of detail expected in a non-programmatic wetland finding is commensurate with the impact severity and mitigation complexity.

Statewide Fen Mapping Completed

CDOT contracted with the Colorado Natural Heritage Program to complete statewide fen wetland mapping within and adjacent to CDOT rights-of-way. The field work and reporting was completed in July 2018. Because the files are enormous, the final report and fen site descriptions can be found on a Google Drive here - https://drive.google.com/open?id=1pjWQ3IkjA8bRQ1_X-RZLRw65gDwEzd04

Additionally, these data are uploaded to CDOT's OTIS site and can be found as a layer called "Potential Fen Wetlands". 

Please contact Becky Pierce with any questions concerning these data. 

Wetland Data Collecting Procedures

CDOT developed procedures for collecting wetland data (i.e using GPS to map wetland boundaries). All data for projects that includes wetland delineations must be provided using the following procedures: Wetland Data Procedure
