Subject: Public Notice for the Fort Carson 4th ID Vehicle Bridge and Road Project
Summary: The U.S. Army Corps of Engineers, Albuquerque District, is evaluating a permit application for the Fort Carson Army Garrison to reconstruct the intersection of Butts Road, Bad Toelz Road, and the Tank Trail, also known as the “Crow’s Foot” intersection. Details of the proposed project are provided below and in the attached maps and drawings. The purpose of this public notice is to inform interested parties of the project and to solicit comments.
Applicant: U.S. Army Garrison Fort Carson, Director of Public Works, 1626 Evans Street, Building 1219, Fort Carson, Colorado 80913.
Agent: Damon Birkby, U.S. Army Corps of Engineers, Omaha District, 1616 Capitol Avenue, Omaha, Nebraska 68102.
Location: The project is located at the intersection of Unnamed Ditch, Butts Road, and Bad Toelz Road (“Crow’s Foot”) in Section 28, T15S-R68W. Latitude 38.718º N, Longitude -104.778º W, El Paso County, Colorado.
Description of Work: The Fort Carson Army Garrison proposes to reconstruct the existing Crow’s Foot intersection to relieve traffic congestion and improve stormwater drainage. The work would involve realignment of Bad Toelz Road to cross Unnamed Ditch with a large culvert north of the Crow's Foot and a new intersection with Butts Road. Butts Road would be realigned and a bridge overpass would be constructed so that Butts Road would pass over the Tank Trail. The Tank Trail would be realigned to pass under Butts Road and would cross Unnamed Ditch at the same location with another large culvert. The culverts would be either precast concrete arch culverts or cast in place concrete box culverts and would include concrete wing walls. In order to correctly align the culvert under the Tank Trail, realignment of Unnamed Ditch would also be required. The bridge overpass would be constructed with pile foundations on each abutment. Finally, in order to accommodate the new road alignment, the applicant proposes to relocate an existing stormwater pond that is currently situated immediately to the north of Bad Toelz Road on the western side of the project area. A total of approximately 210 linear feet of Unnamed Ditch stream channel and approximately 0.9 acres of jurisdictional wetlands would be permanently impacted as a result of the project.
Purpose and Need: The applicant’s stated purpose and need for the project is to improve traffic flow between the main cantonment area of Fort Carson and the new mission areas of the 4th ID CAB in the southern portion of the post and the Special Forces areas located to the west of Crow’s Foot. Furthermore, the purpose and need for the project would be to increase the capacity of stormwater conveyance in Unnamed Ditch and reducing the intensity and duration of flooding at the Crow’s Foot intersection.
Mitigation: The project would result in permanent impacts to approximately 0.9 acre of wetlands adjacent to Unnamed Ditch. The applicant proposes to mitigate for the wetland impacts at a 1:1 ratio by expanding the existing wetlands situated immediately downstream of the Crow’s Foot intersection. In addition to the proposed compensatory mitigation, the applicant proposes to revegetate all areas temporarily disturbed during construction and access using native seed mixes, as appropriate, for the areas disturbed. Post-construction, the applicant would control weeds and other noxious plant species in the project area until native communities become reestablished.
Plans and Data: Drawings showing the location of the work site and other data are enclosed with this notice. If additional information is desired, it may be obtained from the applicant, or from:

Cultural Resources: The Corps has reviewed the latest published version of the National Register of Historic Places and no properties listed in the Register are present at the site of the proposed construction. Consultation with the Colorado State Historic Preservation Office (SHPO) has not revealed any pending nominations. This constitutes the extent of cultural resource investigations by the District Engineer. However, it is possible that presently unknown archeological, scientific, prehistoric, or historic data may be inadvertently lost or destroyed by the work accomplished under the requested permit. In the event that cultural resources are found, the permittee would be required to stop all work and the SHPO would be contacted for advice on the appropriate action to be taken.
Endangered Species: The Corps’ preliminary review indicates this project will not impact any federally listed threatened or endangered species or critical habitat.
State Water Quality Certification: The applicant has applied to the Colorado Department of Public Health and Environment for certification that this work is in compliance with applicable State water quality standards. The applicant is responsible for obtaining all other required federal, state, and local authorizations for this work.
Evaluation Factors: The decision whether to issue a permit will be based on an evaluation of the probable impacts, including cumulative impacts, of the proposed activity on the public interest. That decision will reflect the national concern for both protection and utilization of important resources. The benefit that may be reasonably expected to accrue from the proposal must be balanced against its reasonably foreseeable detriments. The evaluation of the impact of this activity will include application of the guidelines promulgated by the EPA Administrator under authority of Section 404(b) of the Clean Water Act. All factors relevant to the proposal and the cumulative effects will be considered; among these are conservation, economics, aesthetics, general environmental concerns, wetlands, historic properties, fish and wildlife values, flood hazards, floodplain values, land use, navigation, shore erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, considerations of property ownership, and, in general, the needs and welfare of the people.
If the District Engineer determines that the project complies with the 404(b)(1) guidelines, he will grant the permit unless issuance would be contrary to the public interest.
In accordance with environmental procedures and documentation required by the National Environmental Policy Act of 1969, an environmental assessment will be prepared for this project. Upon completion, the assessment may be seen at the U.S. Army Corps of Engineers, Albuquerque District Office, at the address given above.
Comments: Any comments concerning this project should be received by the District Engineer no later than February 17, 2014. Comments received after the end of the public notice comment period will not be considered. However, more time may be given if a request, with a valid reason, is received prior to the suspense date. The Corps of Engineers is soliciting comments from the public; federal, state, and local agencies and officials; Indian tribes; and other interested parties in order to consider and evaluate the impacts of this proposed activity. Any comments received will be considered by the Corps of Engineers to determine whether to issue, modify, condition, or deny a permit for this proposal. To make this decision, comments are used to assess impacts on endangered species, historic properties, water quality, general environmental effects, and the other public interest factors. Comments are used in the preparation of an Environmental Assessment and/or an Environmental Impact Statement pursuant to the National Environmental Policy Act. Comments are also used to determine the need for a public hearing and to determine the overall public interest of the proposed activity.
Any person may request a public hearing. The request must be submitted, in writing, to the District Engineer within 21 days of the date of this notice and must clearly set forth the reasons for holding a public hearing.
