AGENDA ITEM WORDING: Approval to advertise a Request for Proposals for a demonstration
project for canal debris removal and hauling for the Key Largo area.
ITEM BACKGROUND: During the July 19, 2017 BOCC meeting, a demonstration project was
proposed for a canal debris removal and hauling project for Key Largo. Commissioners agreed to
have the item presented at the August 16, 2017 BOCC meeting for further discussion, subject to staff
presenting the item to the Water Quality Protection Program Canal Restoration Advisory
Subcommittee Meeting on July 28, 2017. At the July 28 meeting, the canal committee members
heard the proposal, and agreed with the need to evaluate alternatives to the air curtain operations and
maintenance concerns. It was discussed that this is a proven methodology for other communities in
South Florida and the committee agreed the pilot program for the Key Largo area would provide the
results needed on whether it is a viable alternative for the air curtains.
This program could offer a potentially more economical alternative to weed gate air curtain systems,
potentially needed in 179 canals. Concerns with air curtains include:
• Long term land use easements required from residents
• Placement of compressors, wind vane, and control panel (10' x 10' area) in resident's lot
• Long term Operations & Maintenance costs (estimated $797 /year /lot)
• Electricity consumption (runs 24 hr. / 7 days a week during unfavorable wind conditions)
• Repairs (boats hitting diffusers)
• Maintenance (quarterly cleaning of diffusers and compressors)
• Replacement of equipment (10 year life span)
• Some homeowners have indicated dissatisfaction with the placement of the equipment and O &M
cost.
The Canal Skimming Program is anticipated to include:
• Weekly waterway cleaning to remove litter and large objects, floating seaweed or seagrass,
growing vegetation that impedes navigation
• Hotline established for residents to report floating seaweed, debris or trash in their canal.
• Trash and debris would be disposed at nearest landfill or reuse facility
• No I ong term casements f rom resi dents
Flexibility to save on operations and maintenance costs may be a potential by structuring the
program to only be needed during favorable winds with heavy seaweed loading.
Note: If the program is successful, an MSBU is anticipated to be required in the future for canals
that receive the service.
