Agenda 07/13/2021 Item #16F 5 (Clam Pass Maintenance)07/13/2021 EXECUTIVE SUMMARY Recommendation to authorize expenditure of Tourist Development Tax funds for Clam Pass maintenance in an amount not to exceed $357,739.80 for construction, engineering and surveying, monitoring, and permitting, authorize the necessary budget amendments, 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 Flori da 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 indicates continued 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 sand placement at Clam Pass Park in January 2020. 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. Additional limited maintenance work was completed in December 2020 which included removal of the sand spit and re-grading the inlet entrance using mechanical equipment. The approximate volume of sand that was relocated within the template approximately 10,000 cubic yards. These maintenance events 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 maintenance work includes two options. Option 1 consists of partial excavation and Option 2 consists of full dredging of the template. The construction plans show the proposed cut and fill areas. The approximate volume of sand to be relocated within the template is on the order of approximately 7,000 cubic yards for a partial excavation, and approximately 11,000 cubic yards for a full dredge. Work is anticipated to start as soon as necessary. Timeline will be dependent on conditions of the inlet over the coming few months. Clam Pass is a small dynamic inlet and conditions may change over time especially following storms. The requested quotes are for two options to allow for inlet maintenance of partial or full dredge of the permitted template depending on inlet conditions over the coming few months. As such Standard Technical Specs states 16.F.5 Packet Pg. 2276 07/13/2021 inlet maintenance work to be conducted outside of nesting season. However, if conditions of the inlet require earlier action due to storms during this 2021 tropical season, work may be necessary prior to Nov 1, 2021. The contractor may provide windows of time for their availability for each option over the 6 months period of August 2021 through February 2022 and required lead time from NTP to mobilization. On May 28, 2021, staff requested quotes from all vendors currently under contract with the County under Agreement No. 19-7624, “Marine Contractor Services.” Two vendors under contract submitted quotes, which were received and opened by staff on June 11, 2021. The bids received are summarized below. VENDOR Quote Option 1 Quote Option 2 TSI Disaster Recovery $ 144,000.00 $ 264,000.00 Quality Enterprises USA., Inc.. $ 218,400.00 $ 343,200.00 Kelly Brothers No Quote No Quote Marine Contracting Group, Inc No Quote No Quote The Engineer of Record has determined that TSI Disaster Recovery is the lowest responsive and responsible quoter, and the Contractor's quote of $264,000.00 is reasonable and consistent with industry standards.

The total estimated cost for Clam Pass maintenance is $206,665.80 for Option 1 and $357,739.80 for Option 2. Funding of $257,826.99 is presently available in TDC Beach Renourishment Fund (195), Project No. 88032 (Clam Pass Dredge). A budget amendment for $100,000 allocating funds from Fund (195) reserves into the Clam Pass Dredge project will be required to fund Option 2. TDC RECOMMENDATION: On June 28, 2021, the Tourist Development Council voted unanimously to authorize an expenditure of Tourist Development Tax funds for Clam Pass maintenance in an amount not to exceed $357,739.80 and made a finding that this item promotes tourism. LEGAL CONSIDERATIONS: This item is approved as to form and legality and requires majority vote for Board approval.- CMG RECOMMENDATION: To authorize an expenditure of Tourist Development Tax funds for Clam Pass maintenance in the amount not to exceed $357,739.80 for construction, engineering and surveying, monitoring, and permitting, authorize the necessary budget amendments, and make a finding that this item promotes tourism.
