Dune Restoration Projec - Beach Renourishment Project
RECOMMENDATION
It is recommended that the Village Council approve the consulting engineering service proposal
for the Dune Restoration Project for the Village of Key Biscayne Beach Renourishment,
submitted by Coastal Systems International, Inc., in the amount not to exceed thirty eight
thousand four hundred and nine dollars ($38,409) pursuant to the engineering proposal
attached hereto.
BACKGROUND
Due to hurricanes in 2005, the dune areas in front of the Silver Sands Motel and the Ocean
Club were compromised. The dunes need to be restored and enhanced. In addition, a dune
exotic species survey will be conducted to map the dune areas vegetated as part of the 2002
Beach Renourishment. The following presents the scope of services to be provided by Coastal
System, as an addendum to the Beach Nourishment contract dated June 6, 2000:
• Field Investigations
• Coastal Permit Applications and Permit Processing
• Initial Scope for Mapping Exotic Vegetation Removal and Replacement with Native
Vegetation
The services for Part 20 (Dune Restoration Mapping) will be completed within 45 days of
receiving a Notice to Proceed and favorable weather conditions.
The funding for this project will be obtained from the Capital Outlay Beach Renourishment line
item.

RE: CONSULTING ENGINEERING SERVICES RELATIVE TO THE DUNE RESTORATION
PROJECT FOR THE VILLAGE OF KEY BISCAYNE BEACH RENOURISHMENT PROJECT,
VILLAGE OF KEY BISCAYNE, MIAMI-DADE COUNTY, FLORIDA
Dear Mr. Nunez:
Pursuant to our recent discussions, Coastal Systems International, Inc. (Coastal Systems) is
pleased to submit this revised proposal relative to the above referenced project. Due to
hurricanes in 2005, the dune areas in front of the Silver Sands Motel and the Ocean Club were
compromised. In addition, a dune exotic species survey will be conducted to map the dune areas
vegetated as part of the 2002 beach renourishment. This scope of services is for the field
investigations, coastal permit applications, and permit processing. A follow-up proposal will be
submitted for construction documents and construction administration.
Additionally, initial scope is included for mapping of exotic vegetation along the balance of the
Village's dune in preparation for implementation of a dune maintenance plan (exotic vegetation
removal and replacement with native vegetation).
The following presents the scope of work for services to be provided by Coastal Systems for The
Village of Key Biscayne (Village):
PART 20 -- DUNE RESTORATION MAPPING
a. Dune Topographic Survey: Coastal Systems will mobilize a survey team to survey beach
profiles in the vicinity of R-103 and R-106 to map the dune erosion. Cross sections spaced at
appropriate intervals (approximately 100') will be obtained utilizing land -based topographic
surveying methods to map approximately 600 linear feet of shoreline. Profiles will extend
from the landward edge of dune offshore to wading depth.

Deliverables: Eight (8) copies of Topographic Surveys signed/sealed
b. Vegetation Mapping: As part of the dune restoration project, dune vegetation planting will
be required after completion of the dune fill areas; removal and replacement of any exotic
vegetation within the project area will also be required by the regulatory agencies. Updated
maps of the 2002 dune restoration area will be prepared by Coastal Systems for use by the
subconsultant, Coastal Growers, Inc. to map exotic species. Coastal Growers will identify
areas of exotic and native species within the dune restoration area and will delineate them on
the map.
c. Dune Revegetation Plans: A layout of replacement dune vegetation will be designed for the
dune restoration area. These sketches will be in a format that is sufficient for permitting with
the regulatory agencies. Species with details and quantities of dune vegetation will be
estimated.
d. Dune Fill Plans: Coastal Systems will post process the survey data and generate a digital
terrain model (DTM) for the dune restoration. Volumes will be calculated, and a truck haul
dune restoration project designed. Permit sketches will be prepared on 8.5" X 11" paper
showing the proposed dune fill cross sections.
Deliverables: Eight (8) copies ofplans, signed/sealed
e. Sand Testing: Coastal Systems will retain a Geotechnical subconsultant to perform
laboratory grain size analysis on three (3) sand samples obtained from the existing dunes.
The test data will be analyzed in accordance with DEP standards and submitted as follows in
tabular form: 1) Sieve number 2) diameter in mm 3) diameter in phi units 4) weight retained
on sieve 5) weight percent retained on sieve 6) cumulative weight retained on sieve 7)
cumulative weight percent retained on sieve. All weights and percentages will be recorded to
the nearest 0.01 gm, a table of mean, median (D50), standard deviation (sorting), silt percent
and carbonate content. Cumulative frequency plots will be provided of each sample. If
composite statistics are calculated, the spreadsheet will be provided as well as a cumulative
frequency curve of the composite. In addition, the existing dune sand will be compared to up
to two (2) commercially available beach compatible dune sand sources. If additional testing,
onsite meetings, or additional coordination with DEP staff are required to identify an
appropriate compatible source of sand for the project, these services will be provided under
Part 24 up to the available budget, or under a separate scope of services.
Deliverables: Sand Test Results

PART 21— DEP CCCL PERMIT FOR DUNE RESTORATION
This scope of services assumes that, as the proposed dune restoration activities are to extend
seaward of the Erosion Control Line (ECL) but remain upland of the mean high water line
(MHWL) and are to take place outside of the marine turtle nesting season, that the Florida
Department of Environmental Protection (DEP) Bureau of Beaches and Coastal Systems will be
the sole regulatory agency with jurisdiction over the project and that authorization will be issued
in the form of a DEP Coastal Construction Control Line (CCCL) Permit with separate DEP
Division of State Lands Consent to use sovereign lands seaward of the ECL. If any additional
authorizations are required, they will be addressed under a separate scope.
a. DEP Permit Application - Dune: The Village will provide Coastal Systems with an
executed (all by property owners) DEP permit application form, and a DEP permit
application fee (amount to be determined). Please note that the DEP will likely require the
riparian (upland) property owners to be co -applicant if the project is to extend landward of
the ECL onto their properties. Copies of warranty deeds for these properties will also likely
be required by the DEP.
Coastal Systems is producing the design plans, 8-1/2" x 14" sized plan reductions, and a
survey meeting the standard requirements of the DEP. The plans and sketches must be
signed and sealed by a registered professional engineer or architect; the survey must be
signed and sealed by a registered land surveyor. The Village will provide a letter to the DEP
indicating their approval and confirming that the project "does not contravene local setback
requirements or zoning or building codes" and "is consistent with the local Comprehensive
Plan." Any additional items required by the DEP will be provided by the Village or by
Coastal Systems under a separate scope of services.
b. DEP CCCL Permit Processing - Dune: Coastal Systems will maintain contact with DEP
staff to expedite their review of the permit request. Coastal Systems will confer with the DEP
as to questions, revisions or additional information that may be required for permit issuance.
Coastal Systems will confer with the Village as to questions, revisions or additional items
that may be required. Under this initial scope, Coastal Systems anticipates providing
approximately 40 hours of permit processing services and addressing approximately two (2)
DEP Requests for Additional Information (RAI). Coastal Systems will also begin to
coordinate with the Florida Fish and Wildlife Conservation Commission (FWC) relative to
any comments they may have regarding the project under this initial permit processing scope;
as the project is to be constructed outside the marine turtle nesting season, comments are
expected to be minimal. Any additional data or analyses required by the DEP or FWC that
are not expressly provided in this contract will be addressed under a separate scope of
services. Any coordination required relative to public comments will be provided under a
separate scope of services.
