SCOPE OF WORK
COLLIER CREEK MODELING STUDY
ADDITIONAL PROFESSIONAL SERVICES IN RESPONSE TO FDEP INPUT
MAY 2019
Introduction
In order to address comments from Florida Department of Environmental Protection (FDEP) to
support permitting of a long term solution for Collier Creek, Collier County (County) has requested
that APTIM make the following adjustments to the existing scope of work for the Collier Creek
Modeling Study (PO#45-179398). These scope of work adjustments are in response to feedback
from FDEP, Rookery Bay Aquatic Preserve (RBAP), and local stakeholders that additional
modeling, project justification, and regional coordination will be required in order to complete a
permit application for the multi-part Tentatively Selected Plan (TSP) for Collier Creek
improvements. These comments were received after agency review of the Collier Creek
Management Plan and Modeling Report completed in November 2018 by APTIM and subsequent
phone conferences.
Task 9: Modeling Final Array of Alternatives
Under this new Task 9. APTIM will utilize calibrated numerical models to evaluate alternative
designs for the proposed new groin, suitable to address FDEP comments described in their March
11, 2019 letter and in a teleconference held on April 5, 2019. The final array of alternatives will
refine the TSP and use it to then evaluate a permeable, impermeable and no groin system
compared to the existing inlet configuration, as requested by FDEP Comparison of the modeling
results will include numerical ranking as used in the Management Plan (APTIM, 2018) and
illustrations to explain the coastal and hydraulic processes of interest to FDEP, such as impact
on currents, sediment transport, scour, shoreline change and bathymetry.
Final Array of Alternatives (subject to minor modification):
1. Existing Configuration (Original Alterative 1 - starting after dredging)
2. Tentative Selective Plan (TSP) Variations
a. Optimization of jetty. groin, channel borders, channel cuts, and depth to meet the
goals described in the April 5 outline and teleconference.
b. Optimized plan with permeable groin or permeable adjustable groin (FAG)
c. Optimized plan with small terminal jetty only and no groin (Original Alterative 6)
Alternative 2a will be refined in an iterative fashion until the simulated performance has been
optimized to a level that aligns with the project objectives. Each alternative will be run for 4 years
and compared to Alternative 1 under the same hydraulic conditions. Results will be analyzed to
calculate initial, advanced and maintenance cut and fill volumes, to compare resulting velocities,
channel width, volume infilled, scour/turbulence intensity. and any impacts landward of the ECL
after 4 years.
The final optimized alternative will be run through the numerical models for up to 8 years, or to
the maximum practical length of time greater than 4 years. If the results show major negative

impacts landward of the ECL or to other habitat areas, APTIM will consider if the next best
performing alternative would have less impacts to State owned lands.
These additional modeling efforts and analysis are being conducted to assist in providing
reasonable engineering assurances of the expected impacts of the proposed Collier Creek
improvements. The modeling results and analysis will be written up and presented in a document
that can be used to support permitting efforts and amend the previously completed Management
Plan and Modeling Report.
Task 10. Stakeholder and Agency Coordination
APTIM will assist Collier County in their efforts to coordinate with local stakeholders such as
Hideaway Beach, Ville de Marco West, The City of Marco Island, RBAP, the Coastal Advisory
Committee (CAC), and the Board of County Commissioners (BOCC), as appropriate. In relation
to the Collier Creek Modeling Study and regional sand management. APTIM will prepare for and
attend up to 3 in-person meetings in Collier County.
As requested by FDEP, a regional sand management plan is to be developed for the Hideaway
Beach/Collier Creek permit. APTIM will assist the County in coordinating with the Hideaway
Beach community and RBAP to come up with a comprehensive sand management plan. In
developing the plan, the following items were specifically requested by FDEP for further
investigation and consideration:
1. Alternative disposal options for material resulting from lagoon dredging such as offshore,
or South Marco Island. Sand Dollar Island is growing and there is a desire to keep the
lagoon open, but current practice of disposing of dredged material onto Hideaway Beach
and RBAP may be having a negative impact on Collier Creek.
2. Environmental and coastal management consequences of allowing Sand Dollar Island to
meld onto the beach and eliminate the lagoon.
3. Reducing the permitted template size of the Hideaway Beach project, east of the lagoon
opening, to eliminate overfilling of the T-groin field.
In addition to local stakeholder coordination, APTIM will assist the County in negotiations and
discussions with FDEP and RBAP related to the quantity of anticipated State land loss (if any),
appropriate mitigation. and easement type. APTIM will develop graphics and perform analyses to
support discussions related to anticipated state lands impacts during- and post-construction of
the proposed Collier Creek improvements. Negotiations may include adjustments of the new
channel's dredge footprint, minor modifications to the proposed structures and expanded disposal
area, and permit or easement conditions as required. Up to three APTIM professionals will
accompany the County for one meeting with FDEP in Tallahassee to discuss this project in-
person, if needed.
Task 7E. Permitting for Selected Plan
Task 7A has been previously completed, and Task 7B is currently in progress with no requested
changes at this time. This Change Order requests that existing Tasks 7C and 7D be closed and
the funds from those tasks be combined into a new Task 7E 'Permitting for Selected Plan'.
This task will include professional services to support permitting of the other features of the final
selected plan; except for the terminal jetty modification, which is covered in existing Task 7B.
Aptim Environmental & Infrastructure, LLC
Project features include: altered Collier Creek dredge template, up to one new groin structure,
expansion of the existing Big Marco/Capri Pass disposal area, and a regional sand management
plan.
The permit application will seek to include an expansion of the Big Marco/Capri Pass disposal
area both horizontally and vertically, potentially including an extension into the Loggerhead
Critical Habitat. This effort will be based on previously collected geological data and may require
a longer consultation period due to the involvement of National Marine Fisheries Service (NMFS).
This scope assumes that this request is one that can be submitted utilizing existing data and
analysis for support, and does not require additional coordination with environmental agencies
beyond an initial request for consultation.
The additional modeling efforts and justifications developed in other tasks will be utilized to
support state and Federal permitting of the selected plan for Collier Creek improvements. APTIM
will prepare and submit the relevant state and Federal permit applications by integrating the
biological, geological, engineering and modeling components. The project description will be
based on the modeling and management plan developed in consultation with local stakeholders
and FDEP. Information to be incorporated into the permit application shall include:
• A description of the existing conditions
• Historical background information
• Justification of the maintenance dredging project at Collier Creek
• A written description of the project's design features
• Anticipated construction methods
• Relevant environmental information
• Relevant geological data
• Permit drawings
• Proposed sand management plan
• Copies of the Collier Creek Feasibly Report, Modeling Reports. and Management Plan
as appropriate
APTIM will prepare the permit or permit modification request for submittal by Collier County and
assist in reply to limited Requests for Additional Information (RAI) from the permitting agencies to
bring the permit request to completion. The County will provide all permit fees directly to the permit
agencies and will be responsible for publication of any public notices. APTIM will work closely
with the County to support agency staff and their permitting review in order to expeditiously secure
final permits, to the greatest extent practical.
Task 8: Reimbursable Expenses
At the time of the submittal of this change order request, $7,254.41 are unbilled within the
reimbursable expenses. APTIM requests that these remaining fees remain available to support
reimbursable expenses related to meetings and coordination.
Caveats
No additional field data collection efforts are planned for in this scope of work. Geological
investigation and development of additional disposal sites, and pre-, during-, and post-
construction support can be provided by APTIM under separate work assignment and are not
included within this change order request.
