SUBJECT: Bayshore & Normandy Shores Golf Course Environmental Remediation and Monitoring,
In May of last year, a series of environmental investigations at the Bayshore and Normandy Shores golf
courses were completed by the City's environmental consultants, Metcalf & Eddy, Inc.. The work
performed included a determination of the extent of the contamination throughout both courses, an
assessment of the degree of risk to human health posed by the contaminants, and the development of limited
remedial action plans. The results from those phases of work were compiled into a Contamination
Assessment Report Addendum, a Risk Assessment Report, and a Remedial Action Plan for each golf
course. The reports were submitted to the Miami-Dade County Department of Environmental Resources
Management for their review and approval.
In December 1999, the DERM completed its review of the submitted documents and a meeting was held
on January 11, 2000, between the representatives of the DERM, the City and the City's consultant, Metcalf
& Eddy, Inc., to discuss the DERM's findings and conclusions prior to the issuance of their final review
letter.
The meeting was positive and the DERM's conclusions were very favorable to the City. In short, there
were two significant decisions made which benefit the City; 1) the DERM agreed with the City's position
that the fairways areas of the course are covered under an "Agricultural Exemption" and therefore do not
need to be remediated (This concession from the DERM reduces the projected remediation costs by
approximately $2,500,000), and 2) the DERM proposed a remediation plan for the maintenance facilities
which was less stringent than the plan proposed by the City.
During the meeting, negotiations ensued over the final response actions and a Remedial Action Plan (RAP)
was agreed upon and approved by the DERM. The approved RAP requires the City to excavate and
remove the most severely contaminated soil from the former chemical storage and mix/load areas within
the maintenance yards at both golf courses. Once the severely contaminated soils have been replaced with
clean fill material, the City is required to "cap" the entire surface of both maintenance yards with a layer
of asphalt. The purpose of the asphalt is to prevent rain water from percolating through the moderately
contaminated soils that will remain in-place beneath the maintenance yards. (Percolating rain water could
"leach" arsenic contaminants from the soil and transport it into the groundwater beneath the site, thereby
causing the contamination to spread.) After the asphalt cap has been installed, the City will be required

to conduct a Groundwater Monitoring Program to demonstrate that the capping and "in-place management"
is working effectively and preventing contaminant migration.
The cost for implementation of the revised RAP at both courses has been estimated as follows:
Bayshore Golf Course
1. Remediation of severely contaminated soil, placement of clean fill, regrading
of site and construction of new stormwater drainage:
2. Asphalt cap and curbing:
3. One- Year Groundwater Monitoring Program:
$134,278
$ 4,625
$ 28.470
Subtotal for Bayshore Golf Course: $167,373
Normandy Shores Golf Course
1. Remediation of severely contaminated soil, placement of clean fill, regrading
of site and construction of new stormwater drainage:
2. Asphalt cap and curbing:
3. Groundwater Monitoring Program:
$120,727
$ 9,350
$ 28.090
Subtotal for Normandy Shores Golf Course: $158,167
Total Estimated Remediation and Monitoring Costs: $325.540
There is a relatively low risk that the capping and in-place management of the moderately contaminated
soils will not be completely effective at preventing contaminant migration. If this proves to be true, the
City may be required to extend the limits of the capped area or take additional remedial actions. Because
of this potential future liability, the City should provide for a contingency fund of at least $150,000.
I am now preparing the necessary Commission Memorandums for the appropriation of funds and the award
of contracts for the implementation of the Remedial Actions and Groundwater Monitoring Programs. The
required items will be completed for inclusion in the agenda for the February 23, 2000 City Commission
meeting.
