Agenda 12/08/2020 Item #16F 1 (Tourist Development Tax Funds: Clam Pass Maintenance Excavation)12/08/2020
EXECUTIVE SUMMARY
Recommendation to authorize expenditure of Tourist Development Tax funds for the Clam
Pass Maintenance Excavation project in the amount of $123,149.40 for construction and
associated engineering, surveying, monitoring, and permitting, and make a finding that this
item promotes tourism.
OBJECTIVE: To select a marine contractor to perform mechanical bypassing and regrading of
accumulated sand and restoration of the Clam Pass inlet channel and banks.
CONSIDERATIONS: Collier County Ordinance No. 2002-27, as amended, established the Pelican Bay
Municipal Service Taxing and Benefit Unit for the purpose of providing street lighting, water
management, beach renourishment, ambient noise management, extraordinary law enforcement service
and beautification, including but not limited to beautification of recreation facilities, sidewalk, street and
median areas, identification markers, and maintenance of conservation or preserve areas. Pelican Bay
Services Division (PBSD) is solely responsible for advising the County on dredging and maintaining
Clam Pass and manages such activities for the County.
Clam Pass is a small inlet in Collier County that supports tidal flow to the wetland preserve of Clam Bay
Natural Resource Protection Area (NRPA). Maintenance dredging is essential to the health of the system
because of the relatively small tidal prism for Clam Bay which is typically at a critical balance between
tidal energy and littoral process at the inlet channel. The Florida Department of Environmental Protection
(FDEP) Clam Pass maintenance dredging Permit No 0296087-001-JC was modified in 2019 (Permit No.
0296087-007-JN) to incorporate minor updates to the disposal fill template and conditions for work
during turtle nesting season. Monitoring of the hydraulic and physical conditions of the Clam Bay system
includes continuous water level and tidal data collection at 4 locations within the bay system.
The monitoring of inlet conditions over the past two months indicates high rates of sand accumulation at
the south bank of the inlet and progressive channel migration northward. There has been persistent flow
of sand from south side of the inlet since the sand placement at Clam Pass Park last winter. Over the
summer months wave energy from the south also accelerated the rate of sand inflow towards the inlet
from the south. A limited maintenance excavation and grading project was completed in April 2020 to
mechanically bypass the sand accumulation at the south side of the inlet and restore the inlet channel to its
design template. This helped restore tidal flow, but the sand has continued to encroach upon the inlet
channel from the south pushing the channel to the north.
The proposed limited maintenance work includes removal of the sand spit and re-grading the inlet
entrance using mechanical equipment. The construction plans show the proposed cut and fill areas
overlaid on a current aerial photo taken on October 8, 2020. The approximate volume of sand to be
relocated within the template is on the order of approximately 5,000 cubic yards, all to be redistributed
and remain within the system. Work is anticipated to start as soon as necessary approvals are obtained
and a Notice to Proceed is issued by FDEP. No work is proposed to be conducted during the sea turtle
and shore bird nesting seasons.
On October 28, 2020, staff requested quotes for this project from all vendors currently under
contract with the County under Agreement No. 19-7624, “Marine Contractor Services.” A virtual
pre-quote meeting was held on November 2, 2020 and three of the four vendors attended. Two
vendors under contract submitted quotes, which were received and opened by staff on November

dump, throw overboard, sink, or misplace any material, plant, machinery, or
appliance, which in the opinion of the OWNER or ENGINEER may be dangerous to, or
obstruct use of the inlet or adjacent areas, the CONTRACTOR shall recover and remove
the same with the utmost dispatch. The CONTRACTOR shall give immediate notice,
with description and location of such obstructions, or misplaced materials, to the
OWNER or his representative, and when required, shall mark or buoy such
obstructions until the same are removed. In the event of refusal, neglect, or delay in
compliance with the above requirements, such obstructions may be removed by the
OWNER, and the cost of such removal may be deducted from any money due or to
become due to the CONTRACTOR or may be recovered under the CONTRACTOR's
bond.
9. BEACH FILL
9.1. The WORK covered by this section consists of furnishing all labor, materials and
equipment and performing all tasks necessary, including stakeout based on control
established by OWNER, for the placement of sand on the beach fill area within the
lines and grades shown on the plans.
9.2. The CONTRACTOR will establish lines and grades for the beach fill phase of the WORK.
Lines and grades will be set in accordance with standard practice and at such
reasonable intervals as will expedite the CONTRACTOR's WORK. The tolerances in the
beach fill grade are plus or minus one half foot on all grades above Mean Low Water.
9.3. CONTRACTOR shall maintain site control as necessary to ensure accurate placement of
the fill. Wherever grade stakes are used within the limits of fill placement, the
CONTRACTOR will be responsible for the removal of all stakes prior to completion of
the project. Wooden stakes shall not be used. CONTRACTOR shall be responsible for
keeping a record of all grade stakes used in the project either for fill, grading or
excavation. Grade stake logs shall be provided weekly indicating all; new stakes
placed; stakes in place; and stakes removed.
9.4. Only beach quality material is to be placed on the beach. Based on previous excavating
in this project area, it is anticipated that all of the material to be excavated or graded
can be placed on the beach. However, should material removed from the design cut or
grade be not beach compatible, it may not be placed on the beach. Non‐beach
compatible material, if unavoidable, must be removed and disposed of off‐site at a
location approved by the ENGINEER.
9.5. Placement of beach fill material shall not encroach beyond the continuous well‐
established vegetation line where such a line exists. It shall be the sole responsibility of
the CONTRACTOR to ensure that the existing structures are not damaged in the

the material(s) and restore the area(s) to the original condition. If necessary,
contaminated ground shall be excavated, disposed of as directed by ENGINEER, and
replaced with suitable fill material, compacted and finished with a suitable and
compatible top layer of material and planted as required to reestablish vegetation.
10.6.Additional Costs. No separate payment will be made for the prevention, control, or
abatement of environmental pollution, and all costs in connection therewith or
incidental thereto shall be included in CONTRACTOR’s costs.
10.7. Turbidity
10.7.1. Turbidity monitoring as required in the DEP permit and as described in this
section will be conducted by a qualified, independent third party provided by
OWNER. The CONTRACTOR shall assist the turbidity monitor as necessary, and
