Weld County Road 49 — Cache la Poudre River Crossing
Clean Water Act Section 404(b)(1) Analysis
Scope of Work
Project Description
In order to provide regional north/south connectivity east of Greeley, Weld
County Road 49 (WCR 49) was identified as a 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. Included in this alignment is 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.
Weld County requested that a scope of work and fee estimate be prepared to
determine if any environmental fatal flaws are associated with the preferred
alignment bridge crossing of the Cache la Poudre River, focusing on the potential
for a Clean Water Act Section 404 Individual Permit through the US Army Corps
of Engineers (USACE). Through the existing on-call services contract with Weld
County, FHU will investigate the environmental site conditions, coordinate
approximate bridge sizing, prepare alternative screening documentation
acceptable to the USACE for a preliminary Clean Water Act Section 404(b)(1)
analysis, and the coordination with various resource agencies. They include
Weld County, USACE, US Department of Interior Fish and Wildlife Service
(USFWS), and Colorado Department of Natural Resources Division of Wildlife
(CDOW).
Task 1 — Investigation of Environmental Site Conditions
Purpose
FHU will perform a preliminary analysis to identify environmental issues that may
affect the selection of the preferred alignment bridge crossing of the Cache la
Poudre River. The information gathered and compiled in this task will serve as
the basis for evaluating alternative alignments of the bridge crossing. The intent
is to utilize available information to the maximum extent possible and to conduct
new data collection only as necessary. Analyses shall be performed to identify
the potential impacts to the following resources
• Federal Threatened and Endangered species, and State listed species of
concern habitat
• Known/potential historical resources
• Wetlands and Waters of the US
Subtask 1.1
FHU will obtain existing USFWS and CDOW habitat data for Federal threatened
and endangered species and State listed species of concern. FHU will not
conduct "presence/absence" (trappings) surveys for sensitive species potentially
occurring in the project study area.
WCR 49-Clean Water Act Section 404(b)(1)analysis
Page 1 of 3
FHU will collate existing wetlands data already collected for the project area.
Because it is doubtful that right-of-entry will be obtained from property owners at
the project site, the Consultant will develop a method to estimate wetland
boundaries at the proposed site. It is anticipated that the consultant will visit
similar sites along the Cache la Poudre River where access is available to
determine wetland characteristics that may be indicative of wetland conditions at
the proposed crossing location. Additionally, the consultant will determine if
similar wetlands delineations (a field evaluation will be based upon soils,
hydrology, and vegetation according to the 1987 Corps of Engineers Wetland
Delineation Manual and Regional Supplements) within the areas of the Cache la
Poudre River crossing have previously been surveyed for wetlands. FHU will
then conduct the wetland determination using aerial photography and limited field
reconnaissance.
This information will be summarized in both graphic and tabular forms to produce
a comprehensive representation of the physical characteristics of the study area.
Subtask 1.2
In this task, all of the information compiled in Subtask 1.1 will be reviewed and
interpreted in order to identify opportunities and constraints related to potential
alternative alignments.
Task 2 — Approximate Bridge Sizing
Purpose
The purpose of this task is to develop a conceptual design for each new bridge
crossing of the Cache la Poudre River that can be used to evaluate potential
impacts to wetlands, waters of the US, Federal Threatened and Endangered
species, and State listed species of concern habitat for the preliminary Clean
Water Act Section 404(b)(1) analysis.
Weld County hydraulic staff will collect Federal Emergency Management Agency
(FEMA) and other floodplain/floodway mapping for the project area. A conceptual
design for each new bridge crossing (as identified in the Arterial Corridor Study
and subsequent revisions thereof) will be developed based on the
floodplain/floodway mapping to identify a optimal bridge span and approximate
pier locations. Weld County hydraulic staff will also develop detailed hydraulic
analysis for each crossing identified that will aid in sizing the drainage structure
required for the Cache la Poudre River.
FHU will assist County staff with developing horizontal roadway alignments as
necessary to avoid impacts to wetlands, waters of the US, and Federal
Threatened and Endangered species, and State listed species of concern habitat
identified in the project area as part of Task 1 for identified crossings of the
Cache la Poudre River. FHU will not develop vertical alignments or produce
cross-sections but will consider vertical elements as the alignments are
established to test the viability of the horizontal alignments. The roadway cross-
section for this initial effort will be a 2-lane roadway section instead of the 4-lane
arterial roadway section identified in the Weld County Road 49 Arterial Corridor
Study.

Task 3— Alternative Screening
Purpose
The purpose of this task is to prepare alternative screening documentation
acceptable to the USACE for a preliminary Clean Water Act Section 404(b)(1)
analysis. FHU will work with Weld County and USACE to prepare a purpose and
need statement for the Clean Water Act Section 404(b)(1) analysis. The
conceptual alternatives will be analyzed for purpose and need, cost (size of
bridge structure) and environmental factors (impacts to wetlands, waters of the
US, Federal Threatened and Endangered species, and State listed species of
concern habitat, and known/potential historic resources). FHU will prepare a draft
and final document for review by the USAGE, CDOW, and USFWS.
Subtask 3.1
Information on each alternative will be compiled into an evaluation matrix and
summarized in a preliminary Clean Water Act Section 404(b)(1) analysis
technical memorandum. This technical memorandum is intended to serve as a
component of an individual Clean Water Act Section 404 permit.
Task 4 - Project Coordination
Purpose
FHU will provide appropriate project management of the work to assure that the
scope, budget, and schedule are adhered to. FHU has assumed that no more
than three project coordination meetings will be required to discuss the project
and coordinate the work efforts. One of these meetings is assumed to be a
coordination meeting with the USACE.
Included in this task is one field meeting with the USACE, CDOW, and USFWS
to discuss the project alternatives and site conditions.
