MAINTENANCE CORRIDOR AND BEAVER BRANCH DITCH CLEANOUT IN LIVINGSTON PARISH
NAME OF APPLICANT: Livingston Parish Gravity Drainage District No. 2, c/o D&S Environmental Services, Post Office Box 510, French Settlement, Louisiana, 70733.
LOCATION OF WORK: Within the Lake Pontchartrain Basin, in the Amite River hydrologic unit (HUC 08070202); within the limits of and adjacent to Beaver Branch, beginning south of LA Highway 1019 (Springfield Road) and traversing southerly, terminating at the intersection of Beaver Branch and LA Highway 1024 (Cane Market Road), in Walker, Louisiana, in Livingston Parish.
CHARACTER OF WORK: The applicant proposes to clear impeding vegetation along a 15-foot corridor adjacent to Beaver Branch. The upper 6 inches will be excavated and crushed concrete placed at natural grade in wetlands to create a permanent access route. Additionally, approximately 6,783 linear feet of Beaver Branch will be cleared of any obstructions, de-silted, and re-shaped to the original shape. Connecting lateral ditches that intersect Beaver Branch will also be de-silted, re-shaped, and lined with crushed concrete to prevent future erosion. Excavated material will be distributed in non-wetlands on site with any excess material being placed in Livingston Parish Gravity Drainage District No. 2 maintenance yard. Approximately 0.14 acre of forested jurisdictional wetlands will be impacted by the maintenance corridor, while approximately 2.856 acres of jurisdictional waters will be impacted by ditch cleanout and re-shaping.
The applicant has minimized the impacts as much as practicable. Additionally, appropriate erosion control methods, including silt fencing, hay bales, seeding, etc., will be utilized during and after the construction to prevent impacts to adjacent property. Crushed concrete will also be placed in lateral ditches will help to contain the sediment load and prevent excessive runoff. As compensation for unavoidable wetland impacts the applicant proposes to purchase wetland credits from a Corps approved mitigation bank located in the watershed.

The comment period for the Department of the Army Permit and the Louisiana
Department of Environmental Quality WQC will close 20 days from the date of this joint
public notice. Written comments, including suggestions for modifications or objections
to the proposed work, stating reasons thereof, are being solicited from anyone having
interest in this permit and/or this WQC request and must be mailed, so as to be
received before or by the last day of the comment period. Letters concerning the Corps
of 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. The application for this proposed project is on
file with the Louisiana Department of Environmental Quality and may be examined
weekdays between 8:00 a.m. and 4:30 p.m. Copies may be obtained upon payment of
costs of reproduction. 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 decision to grant or deny the request. If granted, the time
extension will be continuous to the initial comment period and, inclusive of the initial
comment period, will not exceed a total of 30 calendar days. 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.
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 U.S. 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 U.S. 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 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.
The New Orleans District has determined that the proposed project is located in
waters known to be utilized by the west Indian manatee (Trichechus manatus) and
determined that the proposed activity is not likely to adversely affect the species. This
determination is based on the Standard Local Operating Procedure for Endangered
Species of Louisiana (SLOPES), dated October 22, 2014, between the U.S. Army
Corps of Engineers and U.S. Fish and Wildlife Service, Ecological Services Office.
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 n/a 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.
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.
