The Florida Inland Navigation District: Sustainable Statewide Waterway Management Presented by: Bill Aley, P.G.

PRESENTATION OUTLINE Florida Inland Navigation District (FIND) Statewide Dredged Material Management Plan (DMMP) Development Current Operations Recent Regional Sediment Management Opportunity 2

Florida Inland Navigation District History Florida Inland Navigation District (FIND) established in 1927 Long-range planning efforts for ICWW Main purpose to provide lands for disposal Shift in perception occurred in the mid-1980’s regarding dredging/dredged material management Long-Range Dredged Material Management Plan (DMMP) initiated in 1986 Two-phased approach FIND established in 1927 by the Florida Legislature with the purpose of serving as the local sponsor for the Federally authorized ICWW channel along Florida’s east coast between Fernandina Harbor and Miami. FIND provides the USACE with lands for placing material dredged from the federal navigation channel. early days mostly unconfined disposal into open water, salt marshes, and mangrove wetlands created many “spoil islands” throughout the state adjacent to the ICWW channel. Starting in the 1970s the dredging community began to move away from unconfined placement and toward confined disposal in dedicated upland sites. In 1986, the FIND initiated a state wide, long-range, DMMP effort. This is when Taylor Engineering came on board to assist with the planning efforts. The planning process proceeded in a two-phased approach which I’ll touch on next. 3

Florida Inland Navigation District 404 channel miles within two federally-authorized navigation projects Constructed to present depths between 1941 and 1961 Environmentally diverse Multi-billion dollar economic impact 16 tidal entrances 5 deep-water ports The FIND is responsible for maintenance of 404 channel miles of waterway along the east coast of Florida as well as portions of the Okeechobee waterway. These channels were constructed to their present depths between the 1940s and 1960s. From north to south theses channels traverse several different ecological regions and intersect 16 different tidal inlets, to include 5 different deep water ports. The waterway has a multi-billion dollar impact on the State’s economy. 4

INTRACOASTAL WATERWAY FIND ICWW Program Status 41.5 million CY of sediment 60 placement sites 8 beach sites 52 confined upland placement sites The overall program includes a planned permanent infrastructure of 52 upland containment facilities and 8 beach placement sites designed to manage over 41.5 MCY of material. The fine details of this map show that less than twenty of the planned disposal sites are currently in operation (mostly in N FL); a handful are in the final design and permitting process; and property has been acquired for 30 or so sites that have yet to be designed or permitted (mostly south Fl); most of the permitted beach placement sites occur in S Fl.. 5

DMMP DEVELOPMENT Phase I (County-Wide) Plan Elements 50-year dredging requirement Review existing information Define operational reaches Determine storage capacity deficit Develop appropriate management strategy Candidate disposal sites Identify and evaluate existing and additional sites Establish site bank …..a couple slides here on the initial development of the county wide DMMPs. As previously mentioned, the DMMPs were developed in two phases. Phase I assessed county wide dredging needs, defined operational reaches, and initially identified many candidate disposal sites within the individual counties. To date, the Phase I component for the ICWW is now complete in all 12 counties under the FIND’s purview 6

DMMP DEVELOPMENT Phase I Plan Key Principles Provide one (or at most, two) dredged material management sites per reach Provide sufficient capacity for 50-year storage requirement Actively manage all sites as permanent operating facilities During the disposal site selection process shoaling volumes as well as distance to potential disposal sites was considered. With this in mind, operational reaches were broken up into approximately 10 mile segments in which 1-2 disposal sites per reach were identified for aquisition. ~~~~This image shows approximately 25 candidate sites that were selected for St. Lucie County. Of these I believe three were acquired and 1 has been developed to date~~~~ 7

DMMP DEVELOPMENT Phase II (Site-Specific) Key Elements Acquire property Collect topographic, environmental, and geotechnical data Develop preliminary site designs/reports Site management plan Engineering narrative Opinion of probable cost Site permitting and construction Phase II of the DMMP development involved acquisition of disposal sites followed by design, permitting, and construction of these sites. To date, the USACE or the FIND have constructed ~18 of the (52 planned) upland containment facilities, with an additional several facilities included in the five-year construction schedule.

OPERATIONS Ongoing construction of disposal sites Several constructed in recent years Several more currently in final stages of design and/or permitting Proceeding according to a 5-year plan Projects allocated between USACE and FIND DMMA FL-3 Weir Taylor Engineering is currently engaged in design, construction, and operation of many disposal sites throughout the state of Florida. Proceeding according to a 5 year plan that is worked out and refined annual between USACE and FIND. Dania Cutoff Canal Deepening 2013 9

OPERATIONS Operation, maintenance, rehabilitation, ongoing Site expansions Offloading Weir replacement Mowing DMMA NA-1 Feb 2013 Occasionally, we’re not constructing sites from scratch, rather we rehabilitate previously used sites to bring them up to current operational and environmental standards. This slide shows recent rehabilitation of a disposal site, named NA-1, in Nassau County (northern Florida). ~~~~This site was a disposal area used mostly between 1943 and 1960. Here we rehabilitated a previous disposal site to current operational and environmental standards.~~~~ DMMA NA-1 Jan 2014 10

Regional Sediment Management Opportunity St. Lucie County, FL Regional Sediment Management Opportunity 11

Project Overview – DMMA Placement February 2014: FIND tasks Taylor to permit and design Reach I maintenance dredging November 2016: Bids solicited for dredging of 99,000 CY with disposal at DMMA SL-2* 8 contractors present at pre-bid. Lots of interest December 2016: Only one bid received ($7,900,000) 9 miles of pipe : 99,000 CY sediment 12

Beach Placement Area View looking south, away from Fort Pierce Inlet. View looking north, toward south jetty of Fort Pierce Inlet. December 2016: FIND receives letter from St. Lucie County requesting maintenance material placed on beaches January 2017: Taylor submits permit mods for St. Lucie County to add ICWW as borrow source February 8, 2017: Project re-advertised for beach disposal 13

Regional Sediment Management (RSM) RSM* - A systems approach to manage sediments in order to maximize natural and economic efficiencies to contribute to sustainable water resource projects, environments, and communities. Recognizes sediment as a valuable resource for Healthy Systems Regional implementation strategies across multiple projects and business lines to guide investments to achieve long-term economic, environmental, and social value and benefits Enhances relationships with stakeholders and partners to better manage sediments across a region (local actions with regional benefits) Share lessons learned, data, tools, and technology *http://rsm.usace.army.mil/ With multiple permitting options, state and local support, we looked at the project from an RSM standpoint. What is RSM? (see above) So, with those definitions in mind, I’m going to give a brief background on a recent project and then explain how using these principles and ideas made a hopeless project possible while saving millions of dollars for the FIND and the local County government. 14
