EXECUTIVE SUMMARY
Recommendation to approve a time and material Work Order under contract #09-
5262 for engineering to renourish the Marco South Beaches as outlined in the
attached Coastal Engineering Consultants proposal dated June 7, 2010; for Tasks
1, 2, and 3 not to exceed $200,000; approve all necessary budget amendments
and authorize the County Manager or his designee to execute the Work Order.
OBJECTIVE: Approve the Coastal Engineering Consultants proposal dated June 7,
2010 for engineering to renourish the Marco South Beaches and investigate if additional
or modified erosion control structures would lengthen the renourishment cycle for this
beach. Anticipated construction will be FY 12/13 or FY 13/14.
CONSIDERATIONS: It will take several years to secure the permits to modify or install
additional erosion control structures at the Marco South Beach. This study needs to be
undertaken to determine:
1. If additional erosion control structures would lengthen the renourishment cycle
and if so, what would the most likely cost, savings and cycle be. Preliminary
modeling and historical analysis is required is required.
2. If any of the existing structures can be modified to achieve the same result?
Preliminary modeling and historical analysis.
3. If it is justified to repair the existing structures, then permitting requirements are
required and obtain that permit.
4. The quantity and quality of sand that is available at Capri Pass, Caxambas Pass
and Cape Romano Shoals for Marco South beach renourishment.
5. The optimization of beach renourishment scope through modeling.
6. If this project can be combined with the major mainland renourishment project for
savings?
7. Prepare report and presentation for decision making.
ADVISORY COMMITTEE RECOMMENDATIONS: At the June 10, 2010 CAC meeting
recommendation at this time was to approve $200,000 for task 1, 2, and 3. This
recommendation was approved 6 to 1.
At the June 28, 2010 Tourist Development Council meeting recommendation at this
time was to approve $200,000 for task 1, 2, and 3. This recommendation was approved
6 to 0.
FISCAL IMPACT: A budget amendment totaling $100,000 will be necessary moving
dollars from Fund (195) reserves to the current project budget in order to proceed with
this contract. Approval of this budget amendment will reduce budgeted capital reserves
to $11,326,763.
GROWTH MANAGEMENT IMPACT: There is no impact to the Growth Management
Plan related to this action.
LEGAL CONSIDERATIONS: This item has been reviewed and approved by the
County Attorney's Office and is legally sufficient for Board action. - JK

SCHEDULE "A"
WORK ORDER NO. 1
TASK 1: PLAN FORMULATION & PROJECT UPDATE
Agenda Item No. 16D12
July 27, 2010
CEC Contract No. 615451 of 11
Phase A: Beach Fill Volume Update
Utilizing COUNTY provided controlled digital photography and 2009 annual monitoring
surveys (beach profiles, inlet, shoals, etc.); CEC shall apply the permitted beach fill template and
update the volume requirements for the 2012 -13 Beach Renourishment Project following the
description in the FEMA Project Worksheet, Declaration No. 1785DRFL.
Phase B: Borrow Area Screening
Utilizing COUNTY provided borrow area surveys and data, CEC shall conduct an alternatives
analysis of the existing permitted borrow areas including Caxambas Pass (South Marco prior
source), Capri Pass (Hideaway Beach prior source), Tom's Hill (Collier County prior source)
and Cape Romano Shoal (new source). Parameters to be evaluated include quality, quantity
(compared to the fill volume needs defined in Phase 1), location, environmental impacts,
navigation interests, cost, and synergy with Collier County's other beach nourishment project
needs. A compatibility analysis shall be performed using existing sediment data for both the
native beach and the permitted borrow areas. Based on the analysis, CEC shall rank the borrow
areas and recommend the optimal source(s) for inclusion in the Project.
Phase C: Project Description Update
Based upon the results of Phases 1 and 2, CEC shall update the Project Description and
Preliminary Opinion of Probable Construction Cost for the 2012 -13 Beach Renourishment
Project.
Phase D: Structural Alternatives Screening
Building upon the project performance to date, and relying upon our historical perspective of the
South Marco project goals, objectives, permit issues, and design standards, as well as the
COUNTY's other consultants' reporting and analyses, CEC shall conduct an evaluation of fiscal,
environmental, and institutional parameters to screen the following structural alternatives, or
combination of alternatives, for inclusion in the Project.
• Repair existing breakwaters: restore existing structures to their original design templates,
• Repair existing terminal groins: restore existing structures to their original design templates,
• Modify existing breakwaters: relocate. resize, and / or realign existing structures,
• Modify existing terminal groins: relocate, resize, and / or realign existing structures, and
• Enhance existing breakwaters: add new structure(s) to enhance existing structures.
Based upon the analysis, CEC shall rank the structural alternatives and recommend the two most
favorable alternatives for the Modeling Task. The recommendation shall include the justification
for carrying the selected alternatives forward along with the rationale for eliminating the other
alternatives. The purpose of the structural assessment is to complement the beach fill for
enhancing Project performance, extending Project life, and increasing the interval between
renourishment events.

Phase E: Plan Formulation Report
CEC shall prepare and submit to the COUNTY a draft Report to present the results of Plan
Formulation including beach fill volume update, borrow area recommendations, updated Project
Description and Preliminary Opinion of Cost, and structural alternative recommendations. CEC
shall meet with the County to review the results and obtain comments. CEC shall revise and
submit the final Plan Formulation Report to the County.
TASK 2: MODELING
Phase A: Data Collection and Analysis
CEC shall review COUNTY provided data, as well as, request and obtain existing data that may
be available from other governmental agency sources, for example, Rookery Bay, FDEP,
USACE, City of and Marco Island. It is assumed that additional hydrodynamic information will
need to be obtained in order to calibrate the numerical models proposed for use in subsequent
analysis. At this time, the following field data collection program is proposed:
• CEC shall install tide gages and current meters (or combination units) to measure water
levels and velocities at two prescribed locations (offshore and within Caxambas Pass) for a
total period of 30 days. The instrumentation will be recovered mid -month and again at the
end of the month.
• Water level and current velocity data will be downloaded, reviewed and processed to provide
a record of conditions during the 30 day deployment. CEC will then integrate the new
information with similar data obtained from historical sources, noting any trends apparent in
comparison to the historical information.
After completing Plan Formulation and reviewing the existing literature, CEC will recommend
any changes to the COUNTY prior to initiating the field work.
Phase B: Regional Wave and Storm Statistics
Using the existing literature and data related to the general wind, wave and sediment transport
processes affecting the project area, CEC shall develop a general understanding of the wave
energy shaping the area's shorelines and characterize the geomorphic and littoral processes in the
project area. CEC shall prepare tables summarizing the matrix of wave height, period, and
direction conditions to be used in the modeling.
Using the historical storm data available in the literature, CEC shall compile report storm
statistics with respect to wave height, period, direction and return interval and recommend the
design storm parameters for use in the modeling.
Phase C: Model Calibration and Validation
CEC shall perform a detailed modeling analyses of selected alternatives. CEC shall calibrate and
validate the models using historical records such as bathymetric surveys, dredge and fill records,
aerial photography, and collected field data. In concert with model formulation and application,
CEC shall:
• perform a desktop analyses of available wave, tide, sediment, morphology and dredging data
to formulate the appropriate model domain and boundary forcing information;

South Marco Beach Renourishment -& Structural Enhancements Scope of Work
• conduct an analytic assessment of sediment transport and morphological behavior of the
inlet -beach system to formulate appropriate parameters for model application and to identify
a range of reasonable model results;
• apply an integrated 2D numerical model, (such as MIKE 21 or equivalent) including dynamic
coupling of wave, hydrodynamic and morphological modules; and
• validate the model via qualitative comparisons with measured changes and dredge records
and via sensitivity analysis.
The modeling program shall be performed following the guidelines established by FDEP.
Deviations from the guidelines shall be reported to the COUNTY as appropriate.
Phase D: Sediment Budget
Using historical data, CEC shall compute shoreline and volumetric changes. Combined with the
results of the modeling, CEC shall develop the sediment budget for the project area. The
sediment budget shall including estimates of the potential Ion -shore transport rates along Marco
Island central and south beach reaches as well as Kice Island, shoaling rate at Caxambas Pass,
and order of magnitude of gross and net alongshore sediment transport into and out of the Project
area.
Phase E: Alternatives Analysis
Once the model has been calibrated and validated, CEC shall model the beach fill only
alternative and beach fill with the two structural alternatives determined in Plan Formulation. For
each alternative, CEC shall predict sediment transport magnitude and directions, bathymetric
changes, beach fill diffusion, shoal development and channel sedimentation rates. Based upon
the model results, for each alternative, CEC shall:
• depict predicted changes in coastal processes;
• prepare a table and plan -view depiction of the expected sediment budget;
• qualitatively assess the expected performance, advantages and disadvantages;
• assess the likely issues or concerns of permitting agencies, permit requirements, and
feasibility of obtaining permits;
• prepare a conceptual opinion of probable costs including initial costs, maintenance costs, and
annualized costs for a 30 year project fife; and
• summarize the evaluation parameters in matrix format.
Phase F: Modeling Report
CEC shall prepare and submit to the County a draft Report describing the data collection and
analysis, calibration and validation of the model, alternative analysis and results, and
recommendation for the preferred structural alternative to advance to Preliminary Design. CEC
shall meet with the County to review the results and obtain comments. CEC shall revise and
