DREDGING FOR CHANNEL REALIGNMENT OF WEST COLYELL CREEK IN LIVINGSTON PARISH
NAME OF APPLICANT: Livingston Parish Government, c/o ELOS Environmental, LLC, Attn: Rob Van Vrancken, 43177 East Pleasant Ridge Road, Hammond, Louisiana 70403.
LOCATION OF WORK: West Colyell Creek, Section 34; 3, 10, T- 6S and 7S, R3E, between US Hwy 190 on the north side and Buddy Ellis Road on the south end crossing under I-12 at its midpoint near Walker, Louisiana, in Livingston Parish, within the Lake Pontchartrain Basin in hydrologic unit (HUC 08070202), as shown on the attached drawings.
CHARACTER OF WORK: The applicant has requested Department of the Army authorization to clear, dredge, and deposit material to create access and make hydrologic improvements to a section of West Colyell Creek, which includes channel realignment and bottom shaping for increased drainage efficiency. Approximately 48,470 cubic yards of native material will be dredged and redeposited with excess material being place in a non-wetland location off site. The proposed project is approximately 2.4 miles long and will temporarily impact approximately 9.2 acres of “other waters of the U.S.” Approximately 0.6 acre of forested wetlands adjacent to the creek will be cleared for temporary access and approximately 0.63 acre of forested wetlands will be permanently cleared and filled to complete the project.
The applicant stated that they have designed the project to avoid and minimize direct and secondary adverse impacts to the maximum extent practicable. Any further reduction would limit usage of the property and, therefore deem the project impracticable. As compensation for unavoidable wetland impacts, the applicant proposes to mitigate in-kind wetland credits from a Corps approved mitigation bank located in the watershed.

Engineers permit application must reference the applicant's name and the Permit
Application Number, and be mailed to the Corps of Engineers at the address above,
ATTENTION: REGULATORY BRANCH. Similar letters concerning the Water Quality
Certification must reference the applicant's name and the WQC application number and be
mailed to the Louisiana Department of Environmental Quality at the address above.
Individuals or parties may request an extension of time in which to comment on the
proposed work by writing or e-mailing the Corps of Engineers Project Manager listed
above. Any request must be specific and substantively supportive of the requested
extension, and received by this office prior to the end of the initial comment period. The
Section Chief will review the request and the requestor will be promptly notified of the

Corps of Engineers Permit Criteria
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 which reasonably may be expected to accrue from the proposal
must be balanced against its reasonably foreseeable detriments. All factors which may be
relevant to the proposal 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,
considerations of property ownership and, in general, the needs and welfare of the people.
The US Army 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 US Army Corps of Engineers to determine whether to make, modify,
3
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. Comments are also used to
determine the need for a public hearing and to determine the overall public interest of the
proposed activity.
The New Orleans District is unaware of properties listed on the National Register of
Historic Places near the proposed work. The possibility exists that the proposed work may
damage or destroy presently unknown archeological, scientific, prehistorical, historical
sites, or data. Copies of this notice are being sent to the State Archeologist and State
Historic Preservation Officer.
Our initial finding is that the proposed work would not affect any species, nor affect any
habitat designated as critical to the survival and recovery of such species, listed as
endangered by the U.S. Department of Commerce.
Our initial finding is that the proposed work would not affect any species, nor affect any
habitat designated as critical to the survival and recovery of such species, listed as
endangered by the U.S. Department of Interior. Utilizing Standard Local Operating
Procedure for Endangered Species in Louisiana (SLOPES), dated October 22, 2014,
between the U.S. Army Corps of Engineers, New Orleans and U.S. Fish and
Wildlife Service, Ecological Services Office, the Corps has determined that the proposed
activity would have no effect on any listed species.
This notice initiates the Essential Fish Habitat (EFH) consultation requirements of the
Magnuson-Stevens Fishery Conservation and Management Act. The applicant's proposal
would result in the destruction or alteration of up to 0 acres of EFH utilized by various life
stages of red drum and penaeid shrimp. Our initial determination is that the proposed
action would not have a substantial adverse impact on EFH or federally managed fisheries
in the Gulf of Mexico. Our final determination relative to project impacts and the need for
mitigation measures is subject to review by and coordination with the National Marine
Fisheries Service.
If the proposed work involves deposits of dredged or fill material into navigable waters,
the evaluation of the probable impacts will include the application of guidelines established
by the Administrator of the Environmental Protection Agency. Also, a certification that the
proposed activity will not violate water quality standards will be required from the
Department of Environmental Quality, Office of Environmental Services before a permit is
issued.
Any person may request, in writing, within the comment period specified in this notice,
that a public hearing be held to consider this application. Requests for public hearings
shall state, with particularity, the reasons for holding a public hearing. You are requested
to communicate the information contained in this notice to any other parties whom you
deem likely to have interest in the matter.
The applicant has certified that the proposed activity described in the application
4
complies with and will be conducted in a manner that is consistent with the Louisiana
Coastal Resources Program. The Department of the Army permit will not be issued unless
