Subject: Suntree Technologies Baffle Box — Prima Vista, Sabinal Street Drainage Improvements.
Commissioner District 3 — Rusty Johnson
Background Summary:
The Prima Vista neighborhood storm drainage flows to the south east at the intersection of Sabinal
Street and Gallego Avenue. The Stormwater Division performed a drainage study of the occasional
flooding in this area and produced an in -house designed solution that has been approved by SJRWMD.
Part of the design is providing a baffle box treatment system for the stormwater discharging from the
subdivision before it enters the drainage canal north of the Cemetery. The existing drainage does not
provide any stormwater treatment as it crosses Geneva Street and discharges directly into the canal.
The Stormwater Division approached Suntree Technologies to design the baffle box to collect debris,
separate nutrients and skim oils from the water. Suntree was selected due to their proven history of
providing successful proprietary designs that are easily maintained and adhere to the NPDES
requirements by the EPA. Public Works is requesting the Commission approve the purchase of the
baffle box from Suntree in order to expedite the construction process. The installation and additional
drainage improvements will be contracted out under a competitive bidding process.
Public Works recommends awarding a purchase order to Suntree Technologies, Inc. for the proprietary
8' x 8.5' x 14' baffle box as described in the attached proposal for a total delivered cost of $42,070.00.
Issue:
Request the City Commission to approve the purchase of a baffle box from Suntree Technologies, Inc.
Recommendations
Recommend approval to issue a purchase order to Suntree Technologies, Inc., to provide a baffle box as
described in the attached proposal for the Prima Vista drainage improvements project for a not to exceed
amount of $42,070.00.
Attachments:
Suntree Technologies, Inc., Proposal.
Financial Impact:
The $42,070.00 is adequately funded in the Stormwater Division's CIP budget for the drainage
improvements.

Captured Debris

held 10" underwater in a
Nutrient Separating Baffle Box. ( •
After a couple of months with
no rain, the water still has no
smell and is clear. The sediment
can be clearly seen on the bottom,
and small fish and critters have
established a happy and healthy
ecosystem within the structure.
If you are reluctant to touch the water in your stormwater filtration
system because it is septic, then you have a problem because the
next storm event will flush out your system into the environment.

pounds of sediment collected in
a Nutrient Separating Baffle Box
just 30 days after installation.
To the right is a view of foliage and
litter collected within the screen

Baffle Box.
Sizing The Nutrient Separating Baffle Box
Because the entire flow is always treated and head loss is so
minimal, determining the appropriate size of Nutrient Separating
Baffle Box for a project is more often an element of pipe size than
flow rate.

Q Because water flow is not ducted off line for treatment, head loss is minimal
and comparable to a large square catchbasin. Because of this, existing
stormwater systems can be retrofitted with a Nutrient Separating Baffle
Box, without compromising the original design specifications of the
existing stormwater system.
0 All structures are load rated for at least H -20. Standard wall construction of
the structure is 6" thick steel re- enforced concrete. Concrete wall thickness
can be more heavily reinforced and thicker upon request.
0 A wide variety of manhole lids and hatches, and dampers to block off water
flow during servicing, can be incorporated into the structure.
O Screen systems have stainless steel screens bolted into a heavy duty
aluminum framework. The screen systems are hinged to give easy access
to the lower chambers, and have a wide range of adjustments to
accommodate unforeseen variables during installation.
Setting The Structure
Installation OfA Nutrient Separating
Baffle Box In Perry Florida
The hole was dug
starting at 10:00am.
By 3:00pm the same
day, the entire
structure was set in
place with most of
the backfilling done.

Because installation
is so fast, the risk of
washouts when
retrofitting existing
stormwater systems
is dramatically
reduced.

Notice the custom
pipe fitting on the
inflow end. It is designed to accommodate two
18" RCP side by side. To block off the water flow
of submerged or partially submerged pipes
during servicing, internal damper systems are
available.
A Suntree representative is always
available to oversee installation to ensure
a successful project.
