RESIDENTIAL SUBDIVISION IN LIVINGSTON PARISH
NAME OF APPLICANT: First Horizon, LLC, c/o Michael Henry, Hydrik, 2323 Highway 190 East, Suite 2, Hammond, Louisiana 70401.
LOCATION OF WORK: Within the Lake Pontchartrain Basin, in the Amite River hydrologic unit (HUC 08070202); located adjacent to and south of US Highway 190, approximately 0.9 mile east of its intersection with Louisiana Highway 16, near Denham Springs, Louisiana within Livingston Parish.
The work described below was partially completed prior to obtaining a Department of the Army permit and was in violation of Section 301 of the Clean Water Act. All legal issues concerning the unauthorized work have since been deferred.
CHARACTER OF WORK: The applicant has requested authorization to clear, grade and fill a 58.1-acre tract to allow for construction of 221-lot residential subdivision, known as Middlebrook Place Subdivision. Approximately 110,221 cubic yards of native material will be excavated and placed on-site. A total of 9.3 acres of forested wetlandswill be impacted by the proposed development. Of the 9.3 acres, 0.5 acre was mechanically cleared without authorization.
According to the applicant, the project has been designed to avoid and minimize direct and indirect wetland impacts to the maximum extent practicable. Any further reduction, would not meet construction standards and Parish requirements. As compensation for unavoidable wetland impacts the applicant proposes to purchase wetland credits from a Corps approved mitigation bank located in the watershed.
The applicant may be required to fully or partially restore the site to pre-project conditions if issuance of a permit is determined to be contrary to the public interest.

RESIDENTIAL SUBDIVISION IN LIVINGSTON PARISH
NAME OF APPLICANT: First Horizon, LLC, c/o Michael Henry, Hydrik, 2323 Highway
190 East, Suite 2, Hammond, Louisiana 70401.
LOCATION OF WORK: Within the Lake Pontchartrain Basin, in the Amite River
hydrologic unit (HUC 08070202); located adjacent to and south of US Highway 190,
approximately 0.9 mile east of its intersection with Louisiana Highway 16, near Denham
Springs, Louisiana within Livingston Parish.
The work described below was partially completed prior to obtaining a Department
of the Army permit and was in violation of Section 301 of the Clean Water Act. All legal
issues concerning the unauthorized work have since been deferred.
CHARACTER OF WORK: The applicant has requested authorization to clear, grade
and fill a 58.1-acre tract to allow for construction of 221-lot residential subdivision,
known as Middlebrook Place Subdivision. Approximately 110,221 cubic yards of native
material will be excavated and placed on-site. A total of 9.3 acres of forested wetlands
will be impacted by the proposed development. Of the 9.3 acres, 0.5 acre was
mechanically cleared without authorization.
According to the applicant, the project has been designed to avoid and minimize
direct and indirect wetland impacts to the maximum extent practicable. Any further
reduction, would not meet construction standards and Parish requirements. As
compensation for unavoidable wetland impacts the applicant proposes to purchase
wetland credits from a Corps approved mitigation bank located in the watershed.
The applicant may be required to fully or partially restore the site to pre-project
conditions if issuance of a permit is determined to be contrary to the public interest.
The comment period for the Department of the Army Permit and the Louisiana

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

supportive of the requested extension, and received by this office prior to the end 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 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
