Krug Contact Number: 6002 Reviewed By: Department Director. City Manager: ' 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.

( • 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.

To the right is a view of foliage and litter collected within the screen system of a Nutrient Separating 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. L "s S Gtr G- pk Because installation is so fast, the risk of washouts when retrofitting existing stormwater systems is dramatically reduced. i 1 1 T t@ ) � Ill C I °ti =1 ii l ►�'' ;'��, 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. D� 798 Clearlake Road, Cocoa, FL 32922 Ph: 321-637-7552 FAX: 321-637-7554 www.suntreetech.com
