AGENDA ITEM WORDING:
Request approval to negotiate with the proposers in rank order for
the C83 canal restoration project in Key Largo.
ITEM BACKGROUND:
Approval is requested to negotiate a final price and terms and conditions
with the contractors in the order listed. The original Engineers estimate for the C83 project was $2.5
Million, based on the limited sediment and bathymetric data obtained during the Phase II Canal
Management Master Plan. Sediment cores collected during the design phase provided subsequent
The Request for Proposals was issued on 6/27/16. A non-mandatory pre-proposal conference was
held on 7/29/16. Proposals were opened on 8/18/16. Three proposals were received and provided to
the selection committee for independent review and evaluation. The evaluation included a review of
cost, experience, qualifications, technical proposal and miscellaneous other criteria. The selection
committee met on 9/06/16 to discuss and rank the proposals, which were ranked as follows:
Firm Rank Price
Adventure Environmental 1 $1,607,830.00

Earth Tech 3 $1,734,183.50
The Canal #83 Combined Organic Removal and Backfilling project is the first combination muck
removal and backfilling project to be conducted. It is designed for muck removal to depths greater
than -
Amendment Policy 202.8.6 allowed an exemption to Policy 202.8.4 only for the first two organic
removal demonstration projects to be completed with dredging below -6 feet Mean Low Water
without backfilling. Policy 202.8.6 specified that prior to results of 2 years of monitoring at the first
two sites, additional organic removal projects to depths exceeding -6 feet Mean Low Water need to
include backfilling. This Canal #83 project will allow a comparison of the additional water quality
improvement by including backfilling to a muck removal project to assist in future determination as
to whether backfilling is needed after organic removal in order to meet water quality standards. It is

much more expensive to include it.
The presence of the muck in this canal has depleted the dissolved oxygen levels in the canal waters
and the removal of the muck and subsequent backfilling to enhance natural flushing will help to
restore the canal waters to State Department of Environmental Protection Dissolved Oxygen
standards. Canal #83 in Rock Harbor on Grouper Lane in southern Key Largo was selected utilizing
the Canal Management Master Plan ranking criteria. This project will be the new seventh
demonstration canal project to be implemented. This canal is among the worst as to water quality in
the entire County.
