or the party proposing such, and until all required permits or approvals
have been first obtained from the Pennsylvania Department of Environmental
Protection, Bureau of Waterways Engineering and Wetlands, and FEMA.
In addition, Pennsylvania Department of Community and Economic Development,
Strategic Planning and Operations Office, shall be notified prior
to any alteration or relocation of any watercourse. Any party proposing
an alteration to a watercourse must provide all necessary documentation
to certify that the flood-carrying capacity within the watercourse
shall be maintained upon completion of the proposed alteration.
All buildings and structures which represent new construction
and/or substantial improvement shall be firmly anchored in accordance
with accepted engineering practices to prevent flotation, collapse

Any nonresidential structure, or part thereof, having a lowest
floor (including basement) which is not elevated to at least 1 1/2
feet above 100-year flood elevation shall be floodproofed in a completely
or essentially dry manner in accordance with the standards contained
in the publication titled "Floodproofing Regulations" published by
the U.S. Army Corps of Engineers, dated March 31, 1992, or the most
recent revision to said publication. All plans and specifications
for such floodproofing shall be accompanied by a statement certified
by a registered professional engineer or architect which states that
the proposed design and methods of construction are in conformance
with the aforementioned standards.
C. Accessory structures. Accessory structures to a principal building
or use need not to be elevated or floodproofed to remain dry, but
shall comply, at minimum, with the following requirements:
(1)
The structure shall not be designed or used for human habitation
but shall be limited to the parking and storage of vehicles, or for
the storage of tools, material and equipment related to the principal
use or activity.
(2)

affect adjacent properties.
F. Drainage facilities. Storm drainage facilities shall be designed
to convey the flow of stormwater runoff in a safe and efficient manner.
The system shall insure proper drainage along streets and provide
positive drainage away from buildings. The system shall also be designed
to prevent the discharge of excess runoff onto adjacent properties.
When floodproofing methods are utilized in accordance with §
465-1215 of this article, a registered professional engineer or architect shall certify in writing that the floodproofing methods utilized are adequate to withstand flood depths, pressures, velocities, impact and uplift forces and other factors associated with a 100-year flood. The certification shall also indicate the specific elevation in relation to mean sea level to which such structures are floodproofed. In addition to certification of as-built drawings, a certification by an architect or professional engineer shall be required immediately following the completion of construction or substantial improvements, including completion and filing of an elevation certificate and/or a floodproofing certificate as provided by FEMA. This certification must indicate the mean sea level of the lowest floor and/or, as applicable, the mean sea level to which floodproofing measures have been taken. Such certification is required prior to the issuance of an occupancy permit by the Zoning Officer, Code Enforcement Officer or the person so authorized by Lansford Borough to issue an occupancy permit.
