e. Project Formulation. Shore protection projects are
formulated to provide for hurricane and storm damage reduction. On
this basis any enhancement of recreation that may also result is
considered incidental. Such recreation benefits are NED benefits,
however, and are included in the economic analysis. Additional beach
fill, beyond that needed to achieve the hurricane and storm damage
reduction purpose, to better satisfy recreation demand would be a
separable recreation feature requiring separable 50-50 cost sharing.
14-2. Recreation. Shore protection projects (particularly those
featuring beachfill) are innately conducive to beach and shoreline
recreation activities. Provided that hurricane and storm damage
reduction benefits combined with incidentally generated recreation
benefits limited to an amount equal to the hurricane and storm damage
reduction benefits are sufficient in themselves for economic
justification, the Corps will propose undertaking the project as a
HSDR project (all recreation benefits are included in computation of
the overall benefit-cost ratio). If, in this limiting initial
evaluation, a greater amount of recreation benefits is required to be
combined with hurricane and storm damage reduction benefits in order
to demonstrate economic justification, the project is characterized as
being primarily for recreation. As such, it will not be proposed by
the Corps as a Federal undertaking, since recreation developments are
not accorded priority in Civil Works budget decisions. For the same
reason, separable recreation elements in a shore protection project
will not be recommended.

Hurricane and Abnormal Tidal Flood Protection.
a. Federal Interest. Before enactment of WRDA 1986 (Public
Law 99-662), Federal interest in projects to protect against hurricane
and abnormal tidal flooding was established case-by-case based on
specific Congressional authorizations for Corps construction of such
projects. Although project works were usually similar to beach
erosion control works, hurricane protection projects were viewed as
being more like flood control projects. The 1986 Act, however,
authorizes Federal participation in HSDR projects and establishes
cost sharing for that category of projects. WRDA 1988 prohibits
expenditure of Federal funds on construction of HSDR projects unless
the community in which the project is located is then participating in
the National Flood Insurance Program (NFIP). Other than the magnitude
of storms considered there are now no real distinctions between shore
protection measures for hurricane, storm or tidal induced flooding and
erosion. (ER 1165-2-130)
b. Definition. Hurricane and tidal flooding result from
abnormal rises in tidal levels due to storms and from the in-rush of
waters as a result of waves.
c. Cost Sharing. Federal participation in HSDR projects is
usually determined in the same way as for beach erosion control
projects--based on shoreline ownership, shore use, and type and
incidence of benefits as covered in paragraph 14-1.c. In the event a
HSDR project, in whole or part, provides protection from storm wave
action and/or tidal inundation only without providing any shoreline
protection and/or beach erosion control, construction costs are
usually 65 percent Federal, unless the lands protected are Federal, in
which case construction costs are usually 100 percent Federal.
