ATTACHMENT Martin County Engineering Department Ecosystem Restoration and Management Division FY2016 (Oct. 1, 2015 Sept. 30, 2016) List of Significant Achievements All American Ditch Storm Water Quality Improvement Project Finished design, acquired all permits, and successfully awarded an approximately $4.8 million construction contract to Felix Associates of Florida, Inc. for the construction of the project. Successfully obtained and executed grants for a total of $1.5M through an EPA / FDEP Section 319 program and the State Legislative Appropriations. Started construction of the project in August 2016 and is scheduled for completion in December 2017. Blue Green Algae (BGA) Emergency Response Responded through the Martin County Emergency Operations Center to provide technical support and input during an unprecedented blue green algae bloom event that had major impacts on the County. Coordinated with multiple local, state, and federal government agencies and entities, and academic institutions, on water management issues as they related to the status and causes of the algae blooms. Provided technical briefings and support at emergency meetings, community forums (e.g. Rivers Coalition), Indian River Council meetings, and Board of County Commission meetings throughout the emergency event. Provided numerous interviews to national and local media (television, newspaper, and social media) on status updates and other key message points. Conducted blue green algae (BGA) reconnaissance in response to reports of BGA blooms occurring on the C-44 canal and throughout the St. Lucie estuary. Fielded phone calls from individuals and businesses interested in assisting the County in getting rid of the BGA blooms. Developed the initial database on alternative technologies to eradicate BGA and forwarded to the Florida Department of Environmental Protection (FDEP) as the primary agency for approving technologies for implementation. Assisted the FDEP in uploading BGA information to their database and first responders. In order to understand the scope of the impact of the BGA blooms to residents, Martin County contracted with EnviroTeam North America to perform water and air sampling at sites where BGA blooms had formed dense algal mats approximately 5 9 inches thick. Sampling occurred on July 11, August 16 and September 28. Test results did identify microcystin toxins during some of the sampling events in both the air and/or water. 2 of 6

Bob Graham Beach Added new picnic table & installed new bike rack to meet FCT requirements. Cypress Creek Finalized modeling efforts with Tomasello Engineering to update the hydrologic model of the Cypress Creek basin. The hydrologic model quantifies the benefits of County restoration projects within the Loxahatchee watershed. Worked with the Loxahatchee River Project Delivery Team to include Cypress and Kitching Creeks in the Comprehensive Everglades Restoration Project. Previous iterations of the Loxahatchee Plan did not emphasize these tributaries. Danforth Creek Phase II Hybrid Wetland Treatment Technology (HWTT) Finished construction of the HWTT facility which is now operational. Delaplane Completed construction of all Florida Communities Trust (FCT) public access facilities on the site. Improved site control by installing gates, fencing and signage. Designed, fabricated, and installed educational signage. Used mechanical equipment to shred large monotypic stands of exotics including Brazilian pepper and strawberry guava from the property. In total, 12 acres of exotic vegetation were cleared. Exotic Vegetation Removal Received $200,000 in grant funding from FFWCC with no match requirement and removed exotic vegetation from roughly 2,000 acres of conservation lands. Removed exotics from an additional 1,000 acres of conservation land. Treatment of approximately 25 acres of invasive exotics completed in-house. Fertilizer Ordinance Martin County continued to work with the Marine Resources Council to implement the Be Floridian Now program, a summertime fertilizer application ban media education campaign. This program will educate residents and property owners about the impacts of freshwater and storm water discharges on the St. Lucie River and Indian River Lagoon and what they can do to reduce these impacts. This past year a Facebook page was launched in late June 2016 and since then, it has received 95 page likes, and there have been 1,273 posts to the page. The Be Floridian Now web-based survey continued through this year. Nearly 300 people have completed the survey and almost half of those are Martin County residents, showing that the campaign is reaching and engaging the Martin County audience. Of the 123 Martin County respondents who answered the question, 36% were aware of the Martin County fertilizer ordinance. Brochures, a coloring book and new billboards were designed this past year. We were also provided with an event toolkit including a pink and white striped 10 by 10 canopy, banner, plastic flamingos, and flamingo lights to draw the audience in to the booth. 2 P a g e 3 of 6

Willoughby Creek Improvement Project Completed survey and preliminary design activities to construct an approximately 10-acre wet detention system that will treat approximately 385 acres of highly impervious development. MC-2 (Bird Island) Planted 200 green buttonwoods on interior of island to increase bird nesting habitat. Microbial Source Tracking The County received the Final South Fork St. Lucie Estuary and River Microbial Source Tracking Study from the Florida Department of Environmental Protection in February of 2016. The report revealed that sites at Golden Gate, Sandsprit Park, All American Ditch, Danforth Creek West, and the Marina at Haney Creek are areas with onsite disposal systems that are likely leaching into the waterway. The combination of consistently elevated counts of fecal coliform bacteria, the presence of the human marker, and detections of sucralose and/or acetaminophen is indicative of a source of some level of untreated human wastewater. NPDES Permit Compliance Martin County in conjunction with the University of Florida IFAS Extension Office launched the Water Ambassadors program. This program was able to partially fund a Sea Grant Agent position and is a public education program that includes educational goals based on specific storm water issues within the community. The program must include a focus on pollutants of concern for impaired waters and priority waters within the community. The ultimate goal of a public education program is to create knowledge and awareness about how human activities create pollutants in storm water and how changes in behavior can help reduce storm water pollutant loads. Ten full-day workshops were completed over the past year with a total of 95 participants. One rain barrel is raffled off at each workshop. The Sea Grant Agent also promoted the Water Ambassador program during three organizational talks and at seven events targeting an additional 288 people. Engineering staff in conjunction with our NPDES consultant Mock Roos updated the Martin County Storm Water Program Management Manual, the Structural Control Inspection 4 P a g e 5 of 6

Standard Operating Procedures and the Martin County Spill Prevention Containment and Response Program Manual (draft). Developed a Storm Water Decal in English and Spanish. Received the Florida Storm Water Association Outstanding Achievement Award for the Martin County Storm Water Quality Program. Engineering staff worked with the Building Department to improve the use of silt fences during development projects. During review of the building permit applications for structures (mainly single-family residences), the County will require the applicant to demonstrate compliance with Martin County Ordinance, Section 67.405.A, which states, storm water from areas of any construction activities shall be controlled, treated and managed on-site using BMP s so as not to cause an illicit discharge to the County's MS4 or regulated waters on the site plan. The site plan will depict the silt fence, or other best management practice, that will have to be installed prior to and throughout the construction. Engineering staff continues to resolve illicit discharges as they occur within the County. Old Palm City Phase III The Beemats plants were harvested and then replanted in September 2016. The lush green color of the plants is evidence that the mats are working to uptake nutrients. Perry Beach Revised the Florida Communities Trust Management and site plans for Perry Beach. Continued working through design, permitting and engineering for public use facilities. Rio Nature Park Conducted two cleanup events with the Rio Civic Club. River Cove Completed a living shoreline and habitat restoration project.
