Attention: Ms. Lillian Pitts

Reference: Case No.: 02-01-039R
Fishers Island Ferry District, City of New London, CT
, CLOMR Application Revision
Dear Ms, Pitts:
Ocean and Coastal Consultants, Inc. (OCe) on behalf ofthe Fishers Island Ferry District (FIFD),
herein submit the additional information as requested in your letter dated 22 July 2002, for the
above referenced CLOMR application.
1. Attachment 1 provides documentation of the bulkhead's structural stability analysis.
2. The submitted wave force calculations do not assume that the maximum shore-directed
wave forces occur at the same time as the seaward-directed forces under the trough ofthe
wave. The forces were determined independently of one another even though both forces
were shown on the same figure. The figures have been updated to better illustrate the
shore-directed and seaward-directed forces on the bulkhead as separate load cases. The
revised analysis of wave forces is presented in Attachment 2.
3. It should be noted that the proposed construction of the bulkhead will not cause the 1%
annual chance water-surface elevation to increase. Rather, the increase is due to improved
methodology in determining the flood hazard zones over the existing Flood Insurance
Study, which was prepared in 1985. Our experience has shown that the improved
modeling methods recommended by FEMA, including the utilization of the CHAMP
program, give rise to higher base flood elevations than the methodology utilized in older
flood studies.
In order to further demonstrate that the proposed bulkhead is not the cause of the
increased 1 % annual chance water-surface elevation, the existing site conditions were
modeled using the CHAMP program. The model indicates that the flood hazard zones
would still increase to V-Zones (Elevation +15' and +13'), for the existing site
conditions, as a result of the improved methodology. The WHAFIS input and output
files and the existing site plan with transects are included in Attachment 3. A digital copy
of the CHAMP program is included on a disk with this submittal.

Re: Bulkhead Calculations
Fishers Island Ferry Terminal
New London, Connecticut
Dear Ms. Emerle:
This letter summarizes the bulkhead design calculations completed for the
Fishers Island Ferry Terminal project in New London, Connecticut. The
design calculations are attached as Appendix A through D; computed factor
of safeties are summarized below. Calculations were completed with the aid
of a computer program identified as ProSheet by Megatec. Please note that
the word "cross force" within the calculation sheets is synonymous with
"shear force."
The bulkhead is a continuous steel sheet system, for the front exposed face
and the anchor tieback. The design is predicated on the installation of an
AZ-26 steel sheet section at the front water exposed face; this sheet has a
minimum steel thickness of 0.48 in. and a section modulus of 48.4 in'/ft.
The sheeting, which has a total length of about 50 ft., will be driven about
15 ft. below the surface of the naturally-deposited inorganic granular soils,
to a tip at about EI. -40. Ground surface within the bulkhead ranges from
EI. 5 to EI. 7. The bulkhead has been analyzed with respect to shear failure
(cross failure), moment failure, and the adequacy of the tie-backs and
deadman to resist the wave loadings prepared by Ocean and Coastal
Consultants, Inc. The following factor of safety values against moment were
determined:
FACTOR OF SAFETY
CONDITION
ACTUAL MINIMUM
REQUIRED
Static (No Wave) 1.90 1.50
Shore Directed Waves
100 Yr. Storm 2.50 1.25
Mean Low Water 3.14 1.25
Critical Water level 4.09 1.25
Seaward Directed Waves
1 DO-yr. Storm 1.35 1.25
Mean low Water 1.44 1.25
Critical Water level 1.47 1.25

The above wave condition results are for a soil backfill level behind the steel
sheets at EI. +7; the factor of safety values for a soil backfill at EI. +5 are
slightly higher.
Based on our analysis, it is our opinion that the bulkhead sheeting and
tieback system provides an adequate factor of safety to resist the anticipated
static and wave forces. We also believe that the portion of the steel sheet
bulkhead that extends a maximum of 4 ft. above ground surface inside the
bulkhead is sufficient to resist the anticipated wave action.
We understand that a shock pressure analysis is not required for this project.
A memo regarding this issue is attached as Appendix E.
Please call if you have any questions or need additional information at this
time.
Sincerely yours,
/d

Fishers Island Ferry Disbict Bulkhead Design
Per FEMA requirements, breaking wave forces must be considered in the
bulkhead design analysis unless it can be demonstrated that the structure
will not be subject to breaking waves. Breaking waves exert high, short
duration .shock" pressures that act near the region where the wave crests hit
the structure (Shore Protection Manua/pg. 7-180).
acc has detennined that the bulkhead will not be subjected to breaking
waves since the water is very deep at the base of the bulkhead. Even at
mean low water conditions, the water is deep enough so that the 100-year
design wave will not be a breaking wave.
Therefore, acc condudes that the bulkhead does not need to be analyzed
for .shock pressure".
Mean Low Water = -{l.9' NGVD
Depth to mudline = 16.1'
Breaking WfNe Criteria: H = 0.78 . d
H = 8.67 feet
d = 8.67/0.78 = 11.11 (critical depth to cause breaking for 100 year storm wave)
Water depth exceeds critical depth - wave will not break

Summary of Additional Data Required to Support a
Conditional Letter of Map Revision (Conditional LOMR)
Case No.:
02-01-039R
Date: JUL 2 2 2002
Requester:
Mr. Stanley M. White, P.E.
Community No.: 090100
Community: City of New London, New London County, Connecticut
The issues listed below must be addressed by you before we can continue the review of your
request for a conditional LOMR.
1. To consider the proposed bulkhead as a shore protection measure during the base (1 %
annual chance) flood, we require documentation of the bulkhead's structural stability
in accordance with the "Criteria for Evaluating Flood Protection Structures,"
developed by the Coastal Engineering Research Center (CERe) in 1989 (Technical
Publication 89-15). Please provide the appropriate analyses and documentation for
evaluating the bulkhead as outlined in Appendix B of the Federal Emergency
Management Agency's draft document titled Guidelines and SDecifications for Wave
Elevation Determination and V Zone MaDDing. dated March 1995 (copy enclosed).
This information should include, but not be limited to, bulkhead design calculations
and plans considering wave forces and lateral earth pressure, as well as subsurface
information (i.e., boring logs), in-place density, shear test results, soil classification,
and justification of soil parameters used in your analyses.
2. The submitted design calculations indicate maximum shore-directed wave forces
occurring at the same time as seaward-directed wave forces under the trough of the
wave. These forces do not negate each other, but occur at different times. Please
modify your design calculations to reflect maximum shore-directed wave forces and
seaward-directed wave forces occurring at different times.
3. According to the submitted data, the proposed construction of the bulkhead will result
in 1 % annual chance water-surface elevation increases greater than those allowed
under Subparagraph 60.3(e)(I) of the National Flood Insurance Program (NFIP)
regulations. In accordance with Section 65.12 ofNFIP regulations, please. submit the
following itetns:
a. An evaluation of alternatives that would not result in increases in 1 % annual
chance water-surface elevations demonstrating why these alternatives are not
feasible.
b. Documentation of individual legal notice to all affected property owners
notifying them of the proposed increases to the 1 % annual chance water-
surface elevations on their property.
.
c. Certification by a registered professional engineer that no structures are
located in areas that would be affected by the proposed 1 % annual chance
water-surface elevation increases.

Criteria for Evaluatini Coastal Flood Protection Structures
Back2round
Many property owners and communities along the U.S. coast are resorting to the
construction of coastal flood control structures to protect existing or ne''''
development from potential damage associated with hurricanes and other maj or
coastal storm events. Flooding and erosion caused by natural processes, sea
level rise, and/or man-made influences are factors contributing to the decision
to construct structures such as seawalls, revetments, bulkheads, and coastal
levees/dikes. Although there is continued debate on the overall impact of these
coastal structures, their construction and use requires that FEMA evaluate their
effectiveness for reducing flood risk and their viability as an alternative to
the non-structural flood loss reduction approaches required for community
participation in the National Flood Insurance Program (NFIP).
!'he areas protected by coastal flood protection structures are frequently
designated as Coastal High Hazard Areas (V zones) on the Flood Insurance Rate
Maps (FIRMs) published by FEMA. FEMA is often requested to revise FIRMs to
reflect the protection provided by a coastal structure against the base (100-
year) flood. Because of the different types of coastal structures, materials,
and construction methods, FEMA must perform a detailed review of these requests
to assure that the structure is adequately designed and constructed to provide
the stated level of protection, and to withstand the 100-year flooding event.
Part 6S of the NFIP regulations requires that any requestor of a FIRM revision
based on flood protection structures provide an analysis of the revised flood
hazards, demonstrate and certify that the structure is designed and constructed
for 100-year flooding conditions, and provide assurance that the structure will
be maintained. Revision requests based on coastal structures are currently
reviewed on a case-by-case basis using these regulations. A wide variation has
been found in the quality of data submitted. Some possible reasons for this
variation include the requestor's inexperience or unfamiliarity with the
different types of structures, the available design guidance, and/or the base
(lOO-year) flood considered by the NFIP. In order to improve the quality of
information submitted, and the ability of FEMA to review revision requests based
on coastal structures, FE.'{A has decided to establish minimum design criteria that
must be addressed in the request.
FEMA commissioned the U. S. Army Corps of Engineers, Ilaterways Experiment Station
(IlES) , Coastal Engineering Research Center to identify or develop criteria for
evaluating the effectiveness of all types of coastal flood protection structures
in preventing or reducing damages and flooding from the lOO-year event. This
study identified and defined the different coastal structures that provide
protection against flooding to property landward of the structure, and documented
successful and unsuccessful cases for each structure type. The minimum criteria,
considerations, and/or conditions applicable to the lOO-year flooding event that
are necessary for an evaluation of a coastal structure were also identified. !'he
IlES study recommended a procedure using these criteria to evaluate the adequacy,
of a coastal flood protection structure to survive the lOO-year flooding event,
and to provide protection against flooding, wave runup and overtopping, wave
. forces, and erosion.

Protection Structures" was used as the basis for these criteria. These criteria
will also be used to resolve appeal challenges and in the conduct of flood
insurance studies, when sufficient design and construction data are available.
MaDoln~ of areas orotected bv coastal flood orotection structures.
(a) General. For purposes of the NFIP, FEMA will only recognize in its
flood hazard and risk mapping effort those coastal flood protection structures
that meet, and continue to meet, minimum design and maintenance standards that
are consistent with the level of protection sought through the comprehensive
floodplain management criteria established by 44 CFR Part 60.3. Accordingly,
this procedure describes the types of information F~~ needs to recognize, on
NFIP maps, that a coastal flood protection structure provides protection from the
base flood. This information must be supplied to FEMA by the community or other
party seeKing recognition of such a coastal flood protection structure at the
time a flood risk study or restudy is ccnducted, when a map revision under the
provision of Part 65 of this subchapter is sought based on a coastal 'flood
protection structure, and upon request by the Administrator during the review of
previously recognized structures. The FEMA review will be for the sole purpose
of establishing appropriate risk zone determinations for NFIP maps and shall not
constitute a determination by FEMA as to how a structure will perform in a flood
evenc.
(b) Design Criteria. For coastal flood protection structures to be
recognized by FEMA, sufficient evidence must be provided that adequate design,
construction, and maintenance have been undertaken to provide reasonable
assurance of durable protection from the base flood. The following requirements
must be met:
(1) Design Parameters. A coastal flood protection structure must
be designed using physical parameters that fully represent the base (lOO-year)
flooding event, including the following:
(i) Design water levels evaluated should range from the mean
low water level at the site to the 100-year stillwater surge elevation. The full
range of elevations must be examined to determine the critical water level since
the most severe conditions may not occur at either extreme.
(ii) Wave heights and periods must be calculated for each
water level analyzed. At a minimum, significant wave height and periods should
be used for "flexible" structures such as revetments, with larger wave height,
up to the one-percent wave height (1.67 times the significant wave height), used
for more rigid structures such as seawalls and bulkheads. The U.S. Army Corps
of Engineers (USACE) Shore Protection Manual (1984 or later edition), provides
guidance and procedures for determining appropriate wave heights and periods.
(iii) Breaking wave forces under structure-perpendicular
loading must be considered in the design unless it can be de~onstrated that the
structure will not be subject to breaking waves. The very high, short duration
"shock" pressures must be used for low mass structures such as bulkheads, while
only the secondary "non-shock" pressures need to be used for massive structures
such as gravity seawalls. Analyses of the breaking wave forces using methods
such as those identified in the COE report "Criteria for Evaluating Coastal Flood
Protection Structures," (WES TR CERG-59-1S) must be submitted.

ehe seorm surge componene of ehe base flood shall be cwo feee above ehe lOO-year
seillwaeer surge elevaeion.
(3) Toe Proeeceion. The loss of maeerial and profile lowering
seaward of ehe seruceure muse be included in ehe design eieher ehrough ehe
incorporaeion of adequaee eoe proeeceion or an evaluaeion of seruceural seabiliey
wieh poeeneial scour equal Co ehe maximum wave heighe on ehe seruceure.
Engineering analyses such as chose recommended in ehe COE's "Geoeechnical
Engineering in ehe Coaseal Zone" (liES IR CERC-87 -1) or "Design of Coaseal
Reveemenes, Seawalls, and Bulkheads" (COE EM 1110-2-1614) muse be submieeed for
ehe eoe proeeceion, or an analysis of scour poeeneial such as found in "Crieeria
for Evaluaeion Coaseal Flood Proeeceion Seruceures" (liES TR CERC-89-15) muse be
. submieeed. .
(4) Backfill Proeeceion. Engineering analyses of wave runup,
overeopping, and eransmission muse be performed using meehods provided in ehe
USACE repore "Criter~a for_ EV;l.luating. Coastal Prote.ction Structures" (liES TR
CERC-89-15). Where ehe structure height hnot sufficiene co prevent overeopping
and/or wave transmission, proeeceion of ehe backfill must be included in the
design. This should address preveneion of loss of backfill maeerial by rundown
over the seruceure, by drainage landward, under, and laeerally around ehe ends
of ehe struceure; as well as ehrough joines, seams, or drainage openings in ehe
seruceure.
(5) Seruceural Stabiliey, Minimum lIater Level. Analyses of the
abiliey of the seruceures co resise ehe maximum loads associaeed with the minimum
seaward waeer level, no wave aceion, saturaeed soil condieions behind ehe
structure, and maximum eoe scour muse be submieeed.
(i) For coaseal dikes and reveemenes, Ii geoeechnical analyses
of potencial failure in a landward direceion by roeaeional gravity slip must be
submitted.
(ii) For graviey and pile-support seawalls, engineering
analyses of seaward sliding, of seaward overeurning, and of foundaeion adequacy
using the maximum pressures developed in the sliding and overeurning calculaeions
must be submitted.
(iii) For anchored bulkheads, engineering analyses of shear
failure, momene failure, and the adequacy of ehe eiebacks and de admen to resist
ehe loadings muse be submieeed.
(6) Seructural Seabiliey - Crieical lIaeer Level. Analyses of the
ability of the seructure Co resise ehe maximum loads associaced wieh ehe crieical
waeer level, which may be any water level from ehe mean low waeer level co the
100-year stillwater elevaeion, including hydroscatic and hydrodynamic (wave)
loads, saturaeed soil condieions behind the structure and maximum toe scour, must
be submitted.
(i) For coastal dikes and revetments, geotechnical analyses
of poeential failure in a seaward direction by roeational graviey slip and of
foundation failure due to inadequaee bearing serengeh muse be submiteed.

(ii) For revetments, engineering analyses of the rock, riprap,
or armor blocks' stability under wave action; uplift forces on the rock, riprap,
or armor blocks; toe stability, and adequacy of the graded rock and geotechnical
filters must be submitted.
(iii) For gravity and pile-supporced seawalls, engineering
analyses of landward sliding, of landward overcurning, and of foundacion adequacy
using che maximum pressures developed in the sliding and overturning calculations
must be submicted.
(iv) For anchored bulkheads, engineering analyses of shear and
moment failure using "shock" pressures must be submicted.
(7) Material Adequacy. Documentacion and/or analyses must be
submitted'that demonstrate that the materials used for the construccion of the
structure are adequace and sui cable including life expectancy consideracions, for
the conditions that exist ac the sice.
(8) Ice and Impact Alignment. Where appropriate, analyses of ice
and impact forces must be submitted.
(9) Structure Plan Alignment. A shore protection project should
present a continuous structure with redundant return walls at frequent intervals
to isolate locations of failure. Isolated structures or structures with a
staggered alignment must submit analyses of the additional forces from
concentrated, diffracted, and/or reflected wave energy on the different sections
and ends.
(10) Other Design Criteria. FEMA will require that flood protection
structures, regardless of type described above, be evaluated on the basis of how
they may react struccurally co applied forces. Therefore, analyses normally
required of one struccure type may also be required by another cype which would
react in a simila= manner to applied forces. In unique situacions, FEMA may
require thac other design criteria and analyses be submitted to show that the
structure provides adequate proceccion. In such situations, sound engineering
practice will be the scandard on which FEMA will base its determinations. FEMA
will provide the rationale for requiring any additional .informacion.
(c) Adverse Impact Evaluation. All requests for flood map revisions
based upon new or enlarged coastal flood control structures shall include an
analysis of potential adverse impaccs of the structure on flooding and erosion
within, and adjacent, to the protected area.
(d) Community and/or State Review. For coastal flood protection
structures to be recognized, evidence musc be submitted to show chat the design,
maintenance, and impaccs of the structures have been reviewed and approved by the
affected communities and by any Federal, stace, or local agencies that have
jurisdiction over flood control and coastal construction activities.
(e) Maintenance Plans and Criteria. For a coastal flood protection
structure to be recognized as providing protection from the base flood, the
structure must be .naincained in accordance with an official adopted maintenance
plan, and a copy of this plan must be provided to FEMA by the owner of the
structure when recognition is being sought or when the plan for a previously

recognized structure is revised in any manner. All maintenance activities must
be under the jurisdiction of a Federal or state agency, an agency created by
Federal or state law, or any agency of a community participating in the NFIP that
must assume ultimate responsibility for maintenance. This plan must document the
formal procedure that ensures that the stability and overall integrity of. the
structure and its associated structures and systems are maintained. At a
minimum, maintenance plans shall specify the maintenance activities to be
performed, the frequency of their performance, and the person by name or title
responsible for their performance.
(f) Certification Requirements. Data and analyses submitted to support
that a given coastal flood protection structure complies with the structural
design requirements set forth in paragraphs (b) (1) through (10) above must be
certified by a registered professional engineer. Also, certified as-built plans
of the strUcture must be submitted. Certifications are subject: to the definition
given at S 65.2 of 44 CFR Part 65. In lieu of these certification requirements,
a Federal agency with responsibility for design of coastal flood protection
structures may certify that the structure has been adequately designed and
constructed to provide protection against the base flood.
