AGENDA ITEM WORDING:
Approval to advertise a Request for Proposals for Augmented
Aeration Water Quality Improvement Projects for Canals #48, #59, #79, and #80 in Key Largo and
approval of a request to waive the requirement for resident financial contributions towards the
construction costs.
ITEM BACKGROUND:
The Augmented Aeration installation projects are designed to evaluate
the cost and effectiveness of utilizing an in situ (in place) aeration technology which introduces
oxygen to stimulate bacteria and other organisms to improve water quality to state standards. Canals
#48, #59, #79, and #80 in Key Largo were selected utilizing the Canal Management Master Plan
ranking criteria. The selected canals exhibit depleted dissolved oxygen in the water column due to
the presence of organic sediment. The traditional methods of reducing the amount of accumulated
organic sediment require the removal of the material, which is expensive and disruptive to the use of
the canal. County staff wants to test alternative methods that may be a more cost effective means to
improve dissolved oxygen in canals with organic sediment. These projects will provide valuable new
information to the canal restoration program. Four canals were selected to allow potential multiple
awards if more than one alternative technology proposal is received.
Funds are not budgeted for this project. However, DEP has notified the County that $1.5M has been
awarded from the Stewardship funds this year, and that DEP is preparing the grant award document.
These 4 aeration projects will be included in the grant with an estimated value of $200,000, as well
as the $1.3M backfilling project for canal #75.
In addition, Resolution C-4 from the November 14, 2016 Special BOCC Canal meeting was
approved 4-1 as follows:
A RESOLUTION OF THE BOARD OF COUNTY COMMISSIONERS OF MONROE

Staff is requesting to waive the portion of the C-4 resolution requirement for residents to
contribute financially to the construction costs of the augmented aeration canal projects. These
are true research projects, and the results are unknown. Once the technologies have been tested
and if they are deemed successful, residents will then be asked to fund 100% of the operations and
maintenance costs under an MSBU.
PREVIOUS RELEVANT BOCC ACTION:

water quality restoration projects [canal 75 or 76 (Key Largo, backfilling); canals 48, 59, 79 and 80
