CHAPTER 15
STREAM BANK EROSION CONTROL
15-1. The Federal Interest. Remedial or corrective measures for bank
erosion should be considered in studies of regulating river flows.
However, except in serious cases affecting the general public welfare,
and as otherwise stated below, the Federal interest is limited to bank
stabilization measures required as components of flood control,
navigation and other water resources developments. Costs of such
components will be shared in accordance with the basic policies
applicable to the project functions served. Justification may be
judged in terms of economic and environmental damages prevented or
improvement of economic and environmental values, whether the measures
are independent or component parts of larger systems of works.
15-2. Nature of Effects. Bank erosion causes loss of land and
monetary income therefrom, affects the tax base, pollutes streams,
depletes reservoir storage, silts up wetlands and estuaries, and
disrupts ecologic and economic activities. Control of such erosion
would alleviate these effects. However, practicable remedial
measures, limited to those that are economically justified, would
probably have only a limited effect on the overall impact of naturally
occurring bank erosion.
15-3.
Special Continuing Authority.
a. Authority. Section 14 of the 1946 Flood Control Act, as
amended, states that: "The Secretary of Army is hereby authorized to
allot from any appropriations heretofore or hereinafter made for flood
control, not to exceed ,000,000 per year, for the construction,
repair, restoration, and modification of emergency streambank and
shoreline protection works to prevent damage to highways, bridge
approaches, and public works, churches, hospitals, schools and other
non-profit public services when in the opinion of the Chief of
Engineers such work is advisable: Provided, that not more than
||content||
million shall be allocated for this purpose at any single locality
from the appropriations for any one fiscal year." (Project size is
not limited; see c. below.)
b.
Applicablility.
(1) The purpose of work under this authority is to prevent
flood or erosion damage to endangered highways, highway bridge
approaches, and similar, essential and important public works, or
non-profit public facilities. (Not to prevent loss of land per se.)
In addition to major highways systems of national importance, eligible
highways include principal highways, streets, and roads of significant
importance to the community, such as arterial streets, important
access routes to other communities and adjacent settlements, as well
as roads designated as primary farm to market roads. "Public Works"
means those essential facilities which serve the general public and
are owned and operated by the Federal, state or local government, such
as municipal water supply systems, and sewage treatment plants.
"Non-profit public services" are structures or related services fully
open and available to the general public such as churches, and public
and private non-profit hospitals, and schools. (ER 1105-2-100) Also
eligible are known cultural resources whose significance has been
demonstrated by a determination of eligibility for listing on, or
actual listing on, the National Register of Historic Places and/or
