AGENDA ITEM WORDING: Approval to advertise a Request for Qualification (RFQ) for the
Redevelopment of Bernstein Park. Funding is expected to be from the one -cent infrastructure tax.
ITEM BACKGROUND: With the increase of development of housing on Stock Island, Bernstein
Park, the only County Park available on Stock Island to the public, is in need of redevelopment. The
field is low in elevation and is frequently unusable due to poor drainage and the effect of high tides. The
redevelopment would include, but not be limited to, raising the level of the field by 18" — 24"; construct
new restrooms; develop a new baseball field and basketball court; install new playground equipment;
install a new walking track; create a stormwater retention system; and remove the existing dwelling unit.
See attached preliminary analysis for the issue of flooding with budget estimate, civil engineering plans,
and pictures.
PREVIOUS RELEVANT BOCC ACTION: On February lb, 2011, the BOCC approved a Task
Order with Bermello Ajamil & Partners, Inc. for engineering services to provide cost estimates and
design of changes to Bernstein Park to raise the elevation to eliminate flooding and add a soccer field to
the park. There has been no action taken after these services.
CONTRACT/AGREEMENT CHANGES: N/A

Bernstein Park Redevelopment
Bernstein Park, a Monroe County owned park located on Stock Island is in need of
redevelopment due to its tendency to flood during rain events and high tides. This is mainly due
to the low elevation of the site.
These events usually destroy the vegetation and render the park unusable for long periods of
time. The restrooms and parking areas also flood.
Bernstein Park is the only park on Stock Island and is frequently unusable. It would be in the
community's best interest to provide improvements to the park that would increase its
usability, reduce maintenance, improve safety and improve the quality of life for the residents
of the community and Monroe County.
A Monroe County consultant has previously provided a preliminary report, estimate and design
to elevate the site (attached). There is also a need to replace the existing recreational
equipment and restrooms. This previously provided information will be used in the future
design of the park as much as possible.
This request is for Project Management to be authorized to issue a Request for Qualifications
(RFQ) to architect/engineering firms for the design of a new elevated park. This would include
but not be limited to elevating the existing site 1.5' — 2.0' above its present elevation and
construction of a stormwater retention system, new baseball field, soccer field, playground,
basketball courts, walking track, restrooms and parking area. The removal of the existing
residential unit located on the site is also a possibility.
The construction Project is estimated to cost $2m - $4m depending on the number and quality
of the selected recreational items to be provided. The design package is estimated to cost
$200k - $350k.
With the Board's authorization Project Management will issue the RFQ.

Bernstein Park —Preliminary Analysis
Currently, Bernstein Park has an issue with flooding during rain storm events. B&A was commissioned
by the Monroe County Engineering Department to devise a feasible drainage scheme which would
retain a 25-year storm. We have been researching some options, trying to determine what would be
the best and most economical approach to solving this problem. Reviewing the existing survey
elevations, the existing field grading was poor and did not allow for appropriate drainage. Three options
were prepared.
Option 1:
A swale currently exists along the north end of the park, parallel to 5"' Avenue. Our preliminary grading
scheme ties into this existing Swale and surrounds both the soccer and softball field. Drainage well is
placed at the SW corner of the park. This is the lowest cost option that will improve the existing
drainage condition in the park. Preliminary numbers were obtained from Toppino's on the cost of
transporting and placing the fill for the park area. if the fill from the Monroe County site is to be used, it
would cost approx. $40,000 to pick up, transport, dump, and compact the new fill. If the fill had to be
provided, it would be just under $140,000 to furnish, transport, dump, and compact the fill.
For the infield clay, they estimated that the field would require approx. two truckloads. At $50/ton and
each truckload carrying approx. 10 tons, the total in material would be $1,000 but the cost of
transporting would be more based on the exact location of where they obtain this material from. The
above prices are for material only and do not include the cost for mobilization, clearing and grubbing,
contingency, etc. You may have better luck getting this information from them than I've been.
We've included a set of preliminary plans that show the revised grading along with details for the well.
This is our baseline drawing that allows for minimal cost on the project. We've been in contact with Bill
McCluskey and John O'Brien from Jaffer Wells on pricing for their well drilling along with the
encasement. We originally designed a 24" well but they advised against this stating that an 18"
diameter well in a 24" borehole would have similar capacity without the added expense. Therefore,
please disregard the 24" diameter shown on the plans. The total cost for the well would be $34,000.
This does not include the vault or the associated piping which would come out to approximately
$12,000.
Option 2•
This option would involve utilizing a similar grading scheme but we would introduce a bed of stone, filter
fabric, sand, and sodding immediately above. This would allow the entire field to drain efficiently but
there would be a cost associated with this. We have yet to get pricing on this scheme but were working
on it. The benefit is excellent percolation but the issue is that the percolation would be so good, that
the grass above would have to be irrigated to keep it from dying since it wouldn't retain the water for a
significant period of time. Irrigation could consist of a water truck coming by once a week or a full
irrigation system. This option is similar to the soak pit that Mr. Pierce spoke about.
Option 3:
This would involve the use of a closed drainage system. Drainage structures would be spaced as
required around the perimeter of the fields with water draining into them. A pipe network would be
installed underground conveying the water towards the appropriate well. In areas where the elevations
are too low, a pump station would be installed to direct the water to the well. After a preliminary
pricing scheme is developed for option 2 and this option does not go over a set amount, we will look
into pricing out this alternative.
