PROPOSED REMOVAL OF EXISTING ROCK DAM AND SHEET PILE WEIR AND TO IMPLEMENT NEW RIVER CANAL DREDGING PROJECT NEAR GONZALES, LOUISIANA
IN ASCENSION PARISH
NAME OF APPLICANT: East Ascension Drainage District #1, c/o ELOS Environmental, LLC, Attn: Flynn Daigle, 43177 East Pleasant Ridge Road, Hammond, Louisiana 70403.
LOCATION OF WORK: Located along at approximate 16,168-linear foot reach of the New River Canal, in Sections 20, 28, & 30, Township 9 South, Range 3 East, east of Interstate 10, near Gonzales, Louisiana, located in Ascension Parish, as shown on the enclosed drawings (P.O.B.- Latitude 30.23285 N Longitude -90.94662 W, P.O.E.- Latitude 30.23534 N Longitude -90.90567 W). This project is located in the Pontchartrain Basin (Amite River HUC 08070202).
CHARACTER OF WORK: The applicant is requesting a Department of the Army permit authorization for the removal of an existing rock dam located along the western portion of the project site and the removal of an existing deteriorated sheet pile weir on the eastern portion of the project site, and the dredging of an approximate 16,168-foot reach of the New River Canal. The proposed dredging work would take place within the channel using an amphibious excavator. All excavated material is to be hauled offsite to an approved Parish upland disposal site. The purpose of the proposed project is to increase water capacity within New River. The proposed removal of the two existing structures will allow for a continuous flow through the project site. The river is proposed to be dredged to a -2.0 foot elevation with a slope not exceeding 1:4 from both banks. The applicant has claimed that the proposed project will increase drainage capacity within the developed area of the Parish to help prevent flooding. Approximately 18.0 acre of jurisdictional Other Waters of the United States would be directly impacted as a result of project implementation. Approximately 135,000 cubic yards of dredged waterbottom material and 349 cubic yards of rip rap material would be removed from the project area during project implementation. The applicant has claimed that the project has been designed to avoid and minimize direct and secondary adverse wetland impacts to the maximum extent practicable. The applicant is proposing to utilize best management practices during and after the construction phase of the project. The current project does not propose any direct impacts to jurisdictional wetlands and, therefore, compensatory mitigation is not anticipated.

waterbottom material and 349 cubic yards of rip rap material would be removed from the project
area during project implementation. The applicant has claimed that the project has been
designed to avoid and minimize direct and secondary adverse wetland impacts to the maximum
extent practicable. The applicant is proposing to utilize best management practices during and
after the construction phase of the project. The current project does not propose any direct

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, 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 neither affect any species listed as
endangered by the U.S. Departments of Interior or Commerce, nor affect any habitat
designated as critical to the survival and recovery of any endangered species. 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 with the proposed
activity will 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 NA 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 applicable 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.
