Weld County Road 49 — Cache la Poudre River Crossing
Clean Water Act Section 404 Permit—Change Order #1
Scope of Work
In order to provide regional north/south connectivity east of Greeley, Weld County Road
49 (WCR 49) was identified as an arterial corridor between US Highway 34 (US 34) and
State Highway 14 (SH 14). Weld County identified a preferred alignment for this corridor
in the Weld County Road 49 Arterial Corridor Study (Felsburg Holt & Ullevig [FHU]
2004). The preferred alignment was selected because it would best improve north/south
connectivity in this portion of Weld County.
In 2011, FHU worked with Weld County and the US Army Corps of Engineers (USACE)
to determine if the selected alignment over the Cache la Poudre River could be
permitted under the Clean Water Act. Through an alternative screening process, the
USAGE concurred with Weld County that the selected alignment appeared to be the
least environmentally damaging practicable alternative (LEDPA).
FHU submitted a scope of work to Weld County in November 2011 to conduct the Clean
Water Act Section 404 permitting (404 Permitting). Included under the previous scope of
work was a new bridge crossing of the Cache la Poudre River, approximately one mile
west of the confluence of the Cache la Poudre and the South Platte River and a two-lane
roadway from US 34 to WCR 60.5 that utilized the current South Platte River Bridge at
WCR 58.
Weld County has now requested that a scope of work and fee estimate be prepared to
apply for a Clean Water Act Section 404 Individual Permit through the USAGE for a four-
lane facility, which includes a new bridge over the South Platte River at WCR 58.
Additional scope items includes the re-alignment of the Ogilvy Ditch, which is an historic
resource. Through the existing contract with Weld County, FHU will prepare the
necessary documentation required to obtain a Section 404 permit. Major items include,
additional areas of wetland identification, determination of wetland impacts, wetland
permit submittals, historic clearances, and project coordination/meetings.
This scope of work and fee, in combination with the current contract, will achieve the
environmental clearances for WCR 47/49 segment between US 34 and WCR 60.5.
Purpose
FHU is required to collect additional information on wetland boundaries along the project
alignment, specifically at the areas around the new bridge structure at the South Platte
River and WCR 58 and at Plum Creek. FHU will work the county to gain right of entry to
additional sites. If entry cannot be obtained, typical wetland field work cannot be
conducted. FHU will utilize topographic information and aerial photography to estimate
wetland boundaries. This information will be used to determine wetland impacts from the
roadway and bridge improvements. FHU will also utilize existing geographic information
system (GIS) data to refine wetland boundaries, such as Colorado Division of Parks and
Wildlife (CDPW) riparian and wetland vegetation mapping.
The data collected in this step will help identify potential wetland mitigation areas and
mitigation area refinement.
The information collected in this task will be reviewed with the USACE for their approval.
One (1) field visit with the USACE is anticipated in this task.

Page 1 of 3
Purpose
The purpose of this task is evaluate potential impacts to wetlands, waters of the US,
Federal Threatened and Endangered species, and State listed species of concern
habitat in support for an individual Clean Water Act Section 404 permit.
The intent of this task is to use the roadway and bridge design prepared by Atkins to
estimate impacts to wetlands and demonstrate sufficient avoidance and minimization
actions taken to reduce wetland impacts. FHU will provide a conservative, yet realistic
estimate of project related disturbances that could result in wetland impacts. This
approach ensures that the Section 404 Permit will cover all wetland impacts and still
provide opportunities for further minimization, as final design progresses.
Purpose
FHU will prepare all the necessary materials in support of the Clean Water Act Section
404 Permit. The alternatives analysis performed by FHU under the previous task order
will be utilized for the Section 404(b)(1) documentation. Specific items are anticipated to
include:
• Wetland Identification and Characterization
• Documentation of Avoidance and Minimization Efforts
• Impacts Analysis
• Wetland Mitigation Type Selection
• Wetland Mitigation Site Selection
• Wetland Mitigation Design
• Section 404 Permit Submittal
• Section 401 Certification Submittal to the Colorado Department of Health and
Environment
FHU will prepare the documents, graphics, and plans for these items, with assistance
from the County, as appropriate. FHU will prepare the remaining portions of the
submittals.
During the previous design efforts, it was probable that the project could be permitted
under a Nationwide Permit. However, with the additional road surfaces and new bridge
at the South Platte River, the project will likely require an Individual Section 404 Permit.
Purpose
In recent months, the USACE has taken a closer look at historic resources and requiring
analysis by applicants. This scope and fee was prepared to address the needs of the
USACE and State Historic Preservation Office (SHPO) such that results in the issuance
of a Section 404 Permit.
The purpose of this task is necessary because of the plans to realign the Ogilvy Ditch,
which is an historic resource. Because of this impact to a historic resource, an evaluation
of this and other historic resources in the project area are required. The issuance of a
Section 404 permit (Nationwide or Individual) is a federal action and requires that the
USAGE notify the SHPO of the action and potential impacts to historic resources. This
effort is required to comply with Section 106 of the National Historic Preservation Action
of 1966.

In general, the following steps will have to be taken to achieve concurrence with the
SHPO:
• Determine and Coordinate Area of Potential Effects
• Identify Historic Properties within Area of Potential Effects
o Prepare Architectural Forms (per property)
o Conduct Field Visit
o Prepare Management Data Forms
o Prepare Report
• Determine Effect to Eligible Historic Properties
• Mitigate Adverse Effects
FHU will sub-contract with Dill Historians to document the eligibility status of the ditches
and properties in the project area to be on the National Register of Historic Places. The
documentation of such resources requires that the completion of forms that describes
the context of the resource and the characteristics of the structure or feature that serves
as a contributing factor to the eligibility of the site to be listed on the National Register.
These forms must be completed by an historian with sufficient education, training, and
experience to recognize and properly document these resources. These forms are
required for all potential resources in the project area that have potential to be impacted
by the project. A report documenting these forms and results are required and to be
submitted to SPHO for review and concurrence.
Once the eligibility status of these resources are determined and the SHPO concurs with
these eligibility determination, FHU and Dill will determine the types of effects to the
eligible resources from the implementation of the project. This involves the application of
criteria of adverse effects specified in Section 106 through reviewing and understanding
the project design. These effects are documented and sent to SHPO for review and
concurrence. This process usually requires multiple steps with SHPO to achieve
concurrence.
At the current anticipated design, it is anticipated that the realignment of Ogilvy Ditch
could be determined by the SHPO to be an adverse effect to the resource. If this effect is
determined by SHPO, then mitigation will be required by SHPO. This typically results in
a very detailed recordation of the resource. This Level 11 Documentation, or recordation,
includes specific photography requirements and more detailed documentation by an
historian. The Level II Recordation is estimated at about $6,000 per property.
Purpose
FHU will provide appropriate project management of the work to assure that the scope,
budget, and schedule are adhered. FHU has assumed no more than four (4) additional
project coordination meetings will be required to discuss the project and coordinate the
work efforts. These additional meetings is assumed to be a coordination meeting with
the USAGE.
Included in this task is one (1) field meeting with the USAGE, CDOW, and USFWS to
discuss site conditions and proposed mitigation. This meeting will be attended by FHU
and the County.
