SPA-2013-00136-SCO - City of Woodland Park Fountain Creek Stabilization Project

Posted: 3/29/2013

Expiration date: 4/28/2013


Subject: Public Notice for the Proposed City of Woodland Park Fountain Creek Stabilization Project

Summary: The U.S. Army Corps of Engineers, Albuquerque District, (Corps) is evaluating a permit application to stabilize approximately 1,300 linear feet of Fountain Creek to protect adjacent infrastructure and property, including sanitary sewer line crossings, residential buildings, and the American Discovery Trail. 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: City of Woodland Park, 220 West South Avenue, Post Office Box 9007, Woodland Park, Colorado 80866

Agent: Andy Herb, Alpine Ecological Resources LLC (AlpineEco), 1127 Adams Street, Denver, Colorado 80206

Location: The project is located along the Fountain Creek stream channel in Section 24, T12S-R69W, Latitude 38.9882º N, Longitude -105.0496º W, Teller County, Colorado

Description of Work: The applicant proposes to stabilize the Fountain Creek stream channel between Sheridan Avenue and the confluence with downstream East Fork Fountain Creek. The project would involve removal of existing debris and scattered material, such as broken concrete, from previously failed stabilization efforts and installation of 1,146 linear feet of 6-foot high by 8-foot wide concrete box culvert. Additionally, there would be an approximately 150-foot long section of open channel from the downstream end of the box culvert to the confluence with East Fork Fountain Creek. This open channel would consist of a natural sand bottom with riprap protected side slopes. To safely convey flood flows, the applicant proposes to re-contour this section of the channel to have a minimum width of 20 feet with an average width of 40 feet at the confluence. The channel would be flattened in this area to a 0.3 percent grade from the end of the box culvert to the downstream grade control structure. The stream banks would be protected with buried soil riprap, which would allow vegetation to become established. Finally, in order to prevent vertical scouring of the stream and provide future protection against further vertical channel degradation and any subsequent damage to the proposed box culvert, the applicant proposes to install an at-grade steel sheet pile grade control structure just downstream of the East Fork Fountain Creek confluence. In total, the project would include grading of approximately 0.3 acre of stream bed and banks and placement of approximately 5,403.5 dredged/fill material into waters of the U.S., including 750 cubic yards of concrete to construct the box culverts, 325 cubic yards of stone riprap to construct the culvert outlet and stabilize the banks along the downstream open section of stream channel, and 3.5 cubic yards of steel for the construction of the sheet pile grade control structure.

Purpose and Need: The applicant’s stated purpose of the project is to stabilize the Fountain Creek stream channel. The applicant’s stated need for the project is to protect adjacent infrastructure and property, including sanitary sewer line crossings, residential buildings, and the American Discovery Trail.

Mitigation: No impacts to wetlands would occur as a result of this project; therefore, no compensatory mitigation is required. All areas temporarily disturbed during construction and access will be revegetated using native seed mixes, as appropriate, for the areas disturbed. Weeds and other noxious plant species will be controlled post-construction in the project area until native communities are established.

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 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 April 28, 2013. 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.
