RE: Derelict Structure Removal—Tybee Island Oceanfront
Opinion of Probable Cost-to-Construct
Pursuant to your most recent request, I have formulated an updated Opinion of Probable
Cost-to-Construct for the removal of both wall remnants and derelict steel sheet pile groins
located along the oceanfront in the Fort Screven "vicinity". These structures were originally
placed by the Department of the Army beginning in the 1930's. The documentation of the groin
locations is relatively certain. The locations of the wall remnants are not since they "emerge"
and then become reburied with beach fills, seasonal beach profile fluctuations, etc. If the City
intends to pursue derelict structure removal, additional survey and documentation must be done
before the winter of 2014 federal beach renourishment project is performed. Design documents
will also eventually require updating. It is my opinion that the most cost-effective opportunity
for removal however will be immediately after the fill project — essentially, "in the dry" and
above the mean high water line (MHWL). This likewise simplifies the State and Federal permit
requirements.
In reviewing my files, I have relocated the detailed Proposal submitted by the City to
NOAA several years ago which sought federal funding for derelict structure removal. The
Proposal was very well done but unfortunately did not rank high enough to successfully compete
for the limited federal dollars available at the time. In reviewing the document, I am of the
opinion that both the scope-of-work (SOW) and associated cost estimate for the work to be done
are still valid (see Attachment A). This would include the one derelict structure located
northward of the N. federal rock groin—not addressed in 2009. Hence, I would suggest that the
Proposal be submitted to the County in your continuing efforts to seek funds to remove the

derelict structures. A copy of the original Proposal to NOAA is attached for that purpose (see
Attachment B). Due to its bulk, some of the supplementary information submitted to NOAA as
part of that document has been deleted.
If I can provide any further explanation regarding the need to perform this work or the
attached scope and costing, please let me know.
Thank you for your consideration in this matter.

To whom it may concern:
I am writing to request your support of the City of Tybee Island's application for a National Oceanographic and
Atmospheric Administration (NOAA) Grant that will enable our City to remove multiple derelict structures
from our beachfront.
Our application is for a Habitat Restoration Grant which seeks to address the negative impact that the structures
pose for sea turtle nesting habitat. The structures presently include a monolithic concrete sea wall along with
numerous steel sheet pile groins that run perpendicular to the shore--all of which were constructed by the
federal government decades ago. Our City Council has voted in unanimous support of this Grant application
and to that end has committed both in-kind services and matching funds.
The City is partnering with the State of Georgia, Department of Natural Resources on this project. We have
worked with State and Federal agencies to secure all the necessary permits required to initiate removal of the
structures.
In addition to impacting annual sea turtle nesting, the structures likewise present a significant safety hazard for
those who recreate on our public beaches. For that reason, both swimming and boating must be prohibited at
this time at this location.
I would greatly appreciate the favorable consideration of this Grant application by NOAA. Please don't hesitate
to contact me at 912-786-4573 should you have any questions or require additional information.
Thank you for your time and attention to this very important matter to the Citizens of Tybee and the State of
Georgia.
Sincerely, 7 �

PROJECT NARRATIVE
PROJECT INTENT/GOALS
The derelict structure removal project addressed herein will create or maintain jobs in the
"economically challenged" marine construction industry. The latter is essentially an area of
heavy construction oriented directly to the marine environment, i.e., on, over or abutting large
water bodies. This speciality includes the Atlantic Oceanfront shorefront of Tybee Island, GA.
Additional job opportunities would involve professional trades of coastal engineering, surveying
and aerial photography, at a minimum.
A healthy marine industry is generally dependent upon both private and public sector
clientele. Accordingly, public sector expenditures, such as those proposed by the ARRA, can
result in job opportunities potentially lost or threatened by the lack of private sector project
funding. For example, many ports, or port tenants which comprise a segment of work for the
marine construction industry have delayed local project expenditures — pending a major turn in
the national economy.
Simplistically, the scope-of-work for this Grant Application will address nearshore
marine debris removal which directly impacts sea turtle nesting along a segment of Tybee Island,
GA shorefront. A contract would be let to remove six (6) existing derelict sheet pile groins and
up to 3,000-ft±of monolithic concrete shore parallel seawall —all constructed by the Dept. of the
Army in the 1930's or 1940's when they occupied the adjacent upland property formerly known
as Fort Screven. As one might expect, the subject structures presently likewise significantly
adversely affect the public's use of this shorefront for swimming, boating, etc. Removal of the
structures would therefore benefit the City of Tybee Island's tourist based economy and the State
of Georgia in general. Tybee Island is one of only two (2) publicly accessible beaches in the
entire State.
The subject remediation project is unique in that it will provide significant documented
(see Ga. DNR letter) endangered species protection, is fully permitted and essentially shovel-

ready. Only minor reformulations of existing engineering documents are required in order to
seek competitive bids. In December 2008 the Applicant sought RFP's from qualified marine
contracting firms and received three (3) responses for firms both capable and interested in
performing the work. Unfortunately, sufficient local funds were not available to award a
contract for the costs proposed.
It is estimated that both groin and seawall removal would directly benefit 46- Acres of
nearshore habitat presently impacted by the derelict structures. Removal of the monolithic
concrete seawall segments alone would involve the excavation, demolition and transport to an
upland site of up to 7,700 tons of waste material. The volume of debris associated with groin
removal could increase that amount by another 50%.
APPROACH
Background — In December 2008, the City of Tybee Island solicited requests-for-
proposals (RFP #2008-515) from qualified marine contractors for purposes of attempting to
address derelict structure removal. The RFP was based upon limited information regarding the
nature and extent of the structure field. Since that date, substantial additional information has
been obtained from the archives of the Savannah District USACOE regarding the extent and
nature of the original project. Hence, a reformulation of the original plans and specifications is
required for purposes of resoliciting competitive bids.
In December 2008, three (3) cost proposals were received from marine contractors. The
average cost for the work was predicted at the time to be approximately $1.1M. A revised
scope-of-services is required sufficient to address sea wall components to be removed which
were not necessarily addressed by the original solicitation (RFP) distributed to prospective
contractors.
Work Plan Engineering—The first element of work shall be the fast-track reformulation
of the project plans and specifications. A Contract Manual will be formulated sufficient for both
scoping the project elements and subsequently seeking new competitive bids. Note—the original
December 2008 project was not bid. Rather, based upon the limited nature of the information at
N-2
Recovery Act NOAA-NMFS-HCPO-2009-2001709
City of Tybee Island, GA
Derelict Structure Removal Program
hand, "Cost Proposals" were solicited. Note — the costs of upland disposal of the significant
volumes of material to be removed shall be the contractor's responsibility and part of the
structure of the proposed bid package.
Bid — Immediately upon completion of the updated design documents, the project will be
competitively bid. A Performance Bond will be required as part of the project cost as well as
sufficient Insurance Coverage to protect the City of Tybee Island and others during the course of
the marine work. The project engineer will evaluate the bids as well as the qualifications and
requisite work plans of the bidders and make a recommendation to the City Council as to the
most responsive, responsible bidder.
Award — Within 7-days of bid opening, the City shall make an Award to the selected
contractor. Within 7-days, mol of Award, the City will execute a Contract and issue a Notice-
To-Proceed. Note — The Contract shall stipulate that work on the beach may not be initiated
until sea turtle nesting season has been determined to be complete by the Ga. DNR (estimated at
15 September 2009). After that date the contractor may proceed without further restriction. As a
result, the beachfront work can likewise be accomplished primarily outside of tourist season.
Construction — The contractor shall be given a time frame of 30-days or less to mobilize
equipment to Tybee Island and to initiate work. Subsequently, he will be given 5- to 6-months to
complete the removal work and to demobilize from the site. This includes all relevant site
restoration. During the course of the work, the Engineer shall maintain an inspector on site for
purposes of construction observation, compliance with the design documents, and documentation
of material removed from the beach.
Acceptance — Prior to final payment and release of retainage (estimated @ 10%) the
Engineer shall evaluate the work and make recommendations to the City for final acceptance of
the work.
Schedule — A graphic representing the proposed Schedule-of-Events for all activities
follows. With a Notice-To-Proceed, work by the Engineer could begin as early as 1 May 2009.

To whom it may concern:
The Georgia Department of Natural Resources (GADNR) strongly supports the
proposed habitat restoration project involving the removal of relic steel sheet-pile groins
on Tybee Island's ocean beach. GADNR will be partnering with the City of Tybee on
this project to help restore nesting habitat for the Federally threatened loggerhead sea
turtle. GADNR has worked cooperatively with the City of Tybee for over 20 years to
restore and improve sea turtle nesting habitat by monitoring beach nourishment
projects, reducing artificial lighting on the beach, and coordinating Tybee Island's sea
turtle conservation program. GADNR looks forward to providing expertise and
resources to determine the long-term effectiveness of the project on sea turtle
reproductive success.
The loggerhead turtle (Caretta caretta) was listed as threatened under the Endangered
Species Act of 1973 as a result of declines in nesting in the southeastern United States
and high mortality rates associated with commercial fishing activity. The Recovery Plan
for the Northwest Atlantic Population of Loggerhead Turtle Caretta caretta (NMFS-
USFWS, 2008) delineates reasonable actions required to recover and/or protect
loggerhead turtle populations. The removal of failed or ineffective erosion control
structures is considered a high priority action and is important to ensure that the
amount of nesting beach free of barriers to nesting is stable or increasing.
Shore-parallel structures found in the intertidal zone are known to restrict sea turtle
nesting activity by blocking access to nesting habitat. Several shore-parallel structures
are found within the project area. Sea turtle nesting data collected by GADNR
cooperators from 1999-2008 (see figure below) show significant nesting activity on the
northern end of Tybee's ocean beach with the exception of the portion of the project
area with shore-parallel sheet pile groins. We believe these derelict erosion control
structures are restricting sea turtle access to nesting habitat. The removal of these
structures will allow sea turtles access to nesting habitat that is currently unavailable
and will help accomplish one of the high priority goals of the loggerhead recovery plan.
The GADNR will partner with the City of Tybee to monitor the effectiveness of the
derelict groin removal and will provide a report on the effects of the project on sea turtle
nesting activity.

Loggerhead sea turtle nesting, Tybee Island, 1999-2008.
In summary, the GADNR strongly supports the proposed habitat restoration project
involving the removal of relic steel sheet-pile groins on Tybee Island's ocean beach and
will be partnering with the City of Tybee to monitor the long-term effects of the project
on sea turtles. This project ranks as a high priority for the recovery of the Federally
threatened loggerhead sea turtle. Thank you for your consideration of this letter. If you
need further information, please do not hesitate to contact me.
