APPROVAL OF CONSTRUCTION CONTRACT FOR MODIFICATION TO EGRET <br /> MARSH STORMWATER PARK FLOWAY BID NO. 2012053 <br /> Public Works Director Christopher Mora, through a PowerPoint presentation (on file), <br /> provided description and conditions on staff' s request to have Close Construction, LLC perform <br /> floway surface modifications to the Algal Turf Scrubber (ATS) at Egret Marsh Stormwater Park <br /> (Egret Marsh) . He noted that only about 50% of the original grid is operational, and that the <br /> most durable material to replace the entire floway surface is fibermesh concrete . He thereafter <br /> imparted staff' s recommendation to move forward with the project and have Close Construction, <br /> LLC perform the floway repairs at Egret Marsh. <br /> In response to the Board ' s questions, staff provided additional information regarding <br /> whether there would be any environmental impacts from the fibermesh concrete as it ages ; how <br /> the algae would be harvested and if it was usable afterwards ; and the composition of the concrete <br /> fibermesh material . <br /> Vice Chairman O ' Bryan asked about HydroMentia, Inc . ' s patent on the ATS technology, <br /> what the warranty was for the Algal Turf Scrubber at Egret Marsh, and whether the County <br /> should seek a patent on the fibermesh grid system that will replace the old grid material . <br /> Staff disclosed that there had been a 10 -year warranty and the materials (the membrane <br /> and polyester grid mesh) had lasted two years . They also revealed that because HydroMentia <br /> has a patent on the ATS process , the company expects to receive a technology fee at the new PC <br /> South Nutrient Recovery Facility. <br /> . 3 PG 0 .5 6 <br /> € , . <br /> October 16, 2012 15 <br />
