SPK-2012-00295 - Utah County, UT

Posted: 2/1/2013

Expiration date: 2/27/2013


SUBJECT: The U.S. Army Corps of Engineers, Sacramento District, (Corps) is evaluating a permit application to construct Canyon Crossing which includes a regional hospital and trauma unit surrounded by commercial development in Spanish Fork. The project would result in impacts to approximately 4,968 linear feet (0.31-acre) of waters of the United States, including wetlands. This notice is to inform interested parties of the proposed activity and to solicit comments.

AUTHORITY: This application is being evaluated by the Corps under Section 404 of the Clean Water Act for the discharge of dredged or fill material in waters of the United States and by the State of Utah for Section 401 Water Quality Certification.

APPLICANT: Richard Mendenhall, Tenedor, 2733 E. Parleys Way, Suite 300, Salt Lake City, Utah 84109

AGENT:  Nathan Jean, Stantec Consulting, 2950 E. Harmony Road Suite 290, Fort Collins, Colorado 80528, Email:

LOCATION: The 156-acre site is located north of U.S. Highway 6 (US-6) in Section 18, Township 8 South, Range 3 East, Salt Lake Meridian, Latitude 40.1286°, Longitude -111.6399°, Spanish Fork, Utah County, Utah, and can be seen on the UT-SPANISH FORK USGS Topographic Quadrangle.

PROJECT DESCRIPTION: The applicant is proposing to construct a regional hospital and trauma unit surrounded by commercial development. Based on the available information, the overall project purpose is to construct a regional medical facility and commercial center. The applicant believes there is a need for a major health-care facility in the immediate region and for additional retail facilities to support the community. Additional project information is included in Attachment 1: project plan set Sheets 1-7, dated January 7, 2013 and Attachment 2: Supplemental Information.

Approximately 3,583 linear feet of Watercourse A would be filled in order to construct parking lots, roads, and commercial buildings as shown on the attached plan set Sheets 1-7. As compensatory mitigation for these impacts, 2,650 linear feet of channel would be created. The design channel width of created Watercourse A would be approximately 4 feet with a width-to-depth ratio ranging from 12-18, a sinuosity of at least 1.2 and a riparian corridor of 30 to 80 feet, with an average width of approximately 40 feet, or 10 times the width of the bank-full channel. The relocated Watercourse A would be designed as a mixture of step-pool systems and riffle-pool low gradient alluvial reaches.

Approximately 1,358 linear feet of Watercourse B would be filled in order to accommodate parking, access roads, and the regional medical facility building. This channel would be reconstructed adjacent to the Loop Road. The proposed alignment of reconstructed Watercourse B would result in approximately 3,125 linear feet of ditch. The re-created channel width of Watercourse B would be approximately 10 feet, with a width-to-depth ratio ranging from 12-14, a sinuosity of at least 1.2 and a riparian corridor of 30 to 100 feet with an average width of approximately 50 feet, or 5 times the width of the bank-full channel. The relocated channel would be designed as a riffle-pool low gradient alluvial reach.

The relocated channels and other mitigation would be incorporated into the development through signage and discontinuous walking trails.


Environmental Setting. There are approximately 14.93 acres of emergent wetlands, and other waters of the U.S. a within the 156 acre project area. The site is bordered to the west by commercial development and Interstate 15, to the south by commercial development and US-6, to the north by commercial development, railroad tracks and undeveloped land, and to the east by undeveloped uplands, wetlands and fields used for grazing. The project site is a topographically low area in the northern portion of Spanish Fork City. This area collects irrigation tailwater, surface runoff, and stormwater drainage from surrounding uplands and wetlands located north, east, and south of the project area. In addition, groundwater may be a factor in the hydrology present within some portions of the site. The site is characterized as a low-lying flat undeveloped field used for grazing and appears to have been manipulated in the past to support vegetation for grazing or other agricultural practices. The project site is dominated by western wheatgrass (Pascopyrum smithii), cheatgrass (Bromus tectorum), salt grass (Distichlis spicata) and fringed brome (Bromus ciliatus). Past agricultural and stormwater practices likely manipulated the drainage patterns within the project area. In general, water flows within the project area from east to west and eventually discharges into Dry Creek which flows into Utah Lake. There are two main drainages on site, Watercourse A and Watercourse B as depicted on the attached figure Sheet 1 Existing Conditions Plan. The larger perennial drainage, Watercourse B, originates in the northeast corner of the property, is adjacent to wetlands and playas, and flows from the property in the southwest corner. The second and smaller drainage, Watercourse A, originates in the southeast corner of the project area, flows west, then northerly, and discharges into Watercourse B, the primary site drainage.

Alternatives. The applicant has not provided information concerning project alternatives. Additional information concerning project alternatives may be available from the applicant or their agent. Other alternatives may develop during the review process for this permit application. All reasonable project alternatives, in particular those which may be less damaging to the aquatic environment, will be considered.

Mitigation. The Corps requires that applicants consider and use all reasonable and practical measures to avoid and minimize impacts to aquatic resources. If the applicant is unable to avoid or minimize all impacts, the Corps may require compensatory mitigation. The applicant has proposed to compensate for the loss of waters of the U.S. through creation and wetland enhancement at a 5:1 ratio for wetland creation and a 2:1 ratio for wetland enhancement, with no more than 50% of the total mitigation area being creation. The proposed mitigation area is approximately 46,600 square feet, with a total of 23,300 square feet dedicated to wetland creation and 23, 300 square feet dedicated to wetland enhancement.

OTHER GOVERNMENTAL AUTHORIZATIONS: Water quality certification or a waiver, as required under Section 401 of the Clean Water Act, is required for this project. The Utah Division of Water Quality intends to issue Section 401 certification provided the proposed work will not violate applicable water quality standards. Projects are usually certified where the project may create diffuse sources (non-point sources) of wastes which will only occur during the initial construction activity and where best management practices would be employed to minimize pollution effects. Written comments on water quality certification should be submitted to Mr. Bill Damery, Utah Division of Water Quality, P.O. Box 144870, Salt Lake City, Utah 84114-4870 or email on or before March 4, 2013.

HISTORIC PROPERTIES: The Corps will initiate consultation with the State Historic Preservation Officer under Section 106 of the National Historic Preservation Act, as appropriate.

ENDANGERED SPECIES: The proposed activity may affect Federally-listed endangered or threatened species or their critical habitat. The Corps will initiate consultation with the U.S. Fish and Wildlife Service, pursuant to Section 7 of the Endangered Species Act, as appropriate.

ESSENTIAL FISH HABITAT: The proposed project will not adversely affect Essential Fish Habitat (EFH) as defined in the Magnuson-Stevens Fishery Conservation and Management Act.

The above determinations are based on information provided by the applicant and our preliminary review.

EVALUATION FACTORS: The decision whether to issue a permit will be based on an evaluation of the probable impacts, including cumulative impacts, of the described activity on the public interest. That decision will reflect the national concern for both protection and utilization of important resources. The benefit, which reasonably may be expected to accrue from the described activity, must be balanced against its reasonably foreseeable detriments. All factors which may be relevant to the described activity will be considered, including the cumulative effects thereof; among those are conservation, economics, aesthetics, general environmental concerns, wetlands, historic properties, fish and wildlife values, flood hazards, floodplain values, land use, navigation, shoreline erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, consideration of property ownership and, in general, the needs and welfare of the people. The activity's impact on the public interest will include application of the Section 404(b)(1) guidelines promulgated by the Administrator, Environmental Protection Agency (40 CFR Part 230).

The Corps 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 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 other public interest factors listed above. Comments are used in the preparation of an Environmental Assessment and/or an Environmental Impact Statement pursuant to the National Environmental Policy Act.
