AGENDA ITEM WORDING: Approval to advertise a Request for Proposals for a culvert
installation water quality improvement project on Canal 4259 in Big Pine Key, including a
demonstration weed gate, funded by U.S. Treasury "RESTORE" Grant 1 RDCGR170099-01-00.
ITEM BACKGROUND: This item is to approve advertisement of a Request for Proposals for a
culvert installation water quality improvement project on Canal 4259, located between Granada
Avenue and Minorca Drive on Big Pine Key. This construction work is funded by U.S. Treasury
"RESTORE" Grant 1 RDCGR170099-01-00. A culvert is a proven restoration technique that was
vetted during the canal demonstration projects and is anticipated to increase the water quality in
canal 259.
This project includes a demonstration project for a new form of weed gate, a movable physical
barrier gate at the surface of the canal in lieu of a submerged air curtain. If permits can be obtained
for the weed gate, it will be constructed after installation of the culvert. Staff recommends providing
a 2-year period of operations and maintenance (O&M) to test the gate's operation before setting up
a potential assessment to fund the O&M. The O&M may be more cost effective for this form of
weed gate as no electricity is required to operate it. However, it is unknown at this time the extent of
repairs and maintenance needed.
Because the proposed new weed gate is experimental and part of a demonstration project, resident
approval of the weed gate and potential assessment has not yet been requested. A potential
assessment amount is difficult to estimate at this time as the cost, repair record and other relevant
data will not be available until at least 1 year after implementation of the project. An on-site
meeting with the residents was held on July 29, 2021 to provide details of the project. A potential
assessment was discussed, and staff stated that a recommendation would be made to the BOCC
requesting to have the County fund a 2-year period of the operations and maintenance before
implementing an assessment.
It is noted that Grant Agreement No. X7-02D01921-0 from the United States Environmental
Protection Agency funded the design and permitting activities of the demonstration weed gate.

Canal 259 is located between Granada Avenue and Minorca Drive on Big Pine Key and is rated as
"fair" in water quality. This canal was selected based on water quality summary, ease of
implementation and permitting, and cost of implementation. The canal management database and
other associated ranking criteria for the canal restoration project was used in the selection of this
canal and restoration technique. A culvert is a proven restoration technique that was vetted during
the canal demonstration projects and is anticipated to increase the water quality in canal 259.
