Approval of Last Meeting Minutes Mr. Sullivan moved to approve the minutes subject to the following correction: Page 3, line #5 - from "nothing should be considered..." to "nothing cannot be considered... " Second by Mr. Staiger. Carried unanimously 9-0. o Comments from Public Participation from last meeting Gary McAlpin noted that an item has been added to the agenda to allow for Public Comments. o Recap of Last Meetiug Gary McAlpin recapped the previous meeting and outlined the purpose of today's meeting which is to review the modeling progress and discuss the evaluation criteria for proposed solutions for long-term stabilization of Wiggins Pass. o Last Meeting Follow-up . Mission Statement Progress Ms. Kulpa moved to approve the following mission statement for the Wiggins Pass Modeling Evaluation Work Group: "Examine the modeling study results and recommend environmentally and economically sound methods to maintain Wiggins Pass as a safe navigable waterway by minimizing shoreline erosion and achieving long term stabilization of Wiggins Pass through a collaborative process involving Wiggins Pass stakeholders input. ., Second by Mr. Staiger. Carried unanimously 9-0. 2 August 12, 2008 . Other Noue . Modeliug Progress/CP&E Stephen Keehn, PE and Lindino Benedet, Oceanographer of Coastal Planning and Engineering, Inc. recapped the last meeting and noted, as reported, the Pass is primarily affected by wave action from the South to North. They clarified the Pass does have influences from North to South wave direction; however the net effect of sediment activity in area of the Pass is caused by the South to North wave activity. They provided a Power Point Slideshow Presentation regarding the status of their Delft 3D Numerical Modeling Study including work completed since the last meeting. The work included the placing of instruments in the field to collect data on wave patterns and water current activity in the area to be utilized in developing the modeling of alternative solutions to the long-term stabilization of the Pass. They noted, 8 potential solutions have been modeled through the Delft 3D program for their overall effectiveness in achieving the goals of the Discussion Group. These solutions provide a variety of possible alterations in the area of the Pass (re- channeling, placing of sand dikes, etc.), none of which would be considered "structural alternatives." The modeling showed the morphology of the Pass over a I-year time frame upon completion of the proposed solutions. The morphology indicated widths, lengths and depths, etc. of the channel during the I year time period. After review of the modeling, they have determined that the most effective alternative solutions are #3 (permitted channel + Flood + N-S + dike) and #8 (new channel #2 + Flood + N-S + dike). They noted the next step would be to select the most optimal solutions as determined by the Discussion Group and perform the modeling over a longer time frame (4-5 year morphology). A copy of the Slideshow has been posted on the Coastal Zone Management website. A discussion ensued regarding the alternatives potential impacts on Barefoot Beach and Delnor-Wiggins State Park Beach, analyzing wave climates over a longer time frame (20-year period), etc. Lindino Benedet noted that the modeling is based on the initial information obtained and each model takes a substantial amount of time to run, expanding the model to analyze the impacts with longer wave climate data and would be completed as part of the study when the alternatives are narrowed from 8 to fewer as determined by the Discussion Group. . Evaluation Criteria discussion Stephen Keehn and Lindino Benedet presented a preliminary matrix that will aid in evaluating the 8 alternative solutions. This information is part of the slideshow. The matrix would be used to evaluate the merits of the alternatives proposed and aid in the 3 August 12,2008 Discussion Groups ultimate voting for optimal alternative. Further, it needs to be expanded to include Geological and Environmental parameters. Gary McAlpin suggested the Group Members move forward on evaluating alternatives #3 and #8. Robert Steiger, Delnor-Wiggins State Park Manager stated he was under the impression that the solution was to focus on allowing the Pass to return to its 1970 condition as opposed to re-channeling the Pass. Lindino Benedet noted that this is possible, however the condition would allow a Pass depth of 2-3', not the 8-9' depth required for navigation of a 3 foot draft vessel. Gary McAlpin noted that the depth of2-3' would not satisfy the inlet management plan. Further, he recommended that the evaluation of the alternatives address possible impacts on wildlife and/or fish habitats, Barefoot Beach and Delnor- Wiggins Beach. Sally Braem, Environmental Specialist, Florida State Park noted that the impact on the shoals and benthic communities should be addressed as well. . Follow-up for next meeting Following the discussion the Group determined to focus on alternatives #3 and #8 in the following manner: 1) Analyze 20-year storm data (wave and currents patterns, etc.) for the model 2) Conduct a 4-5 year simulation for the morphology of the Pass based on each alternative 3) Analyze the concept ofrepairing Barefoot Beach to its natural condition and study its morphology over the 4-5 year simulation period of each alternative 4) Analyze impacts on Delnor-Wiggins State Park for each alternative 5) Obtain input regarding impacts on Snook habitats for each alternative 6) Analyze impact on the various environmental communities for each alternative 7) Incorporate any necessary geological considerations into the evaluation Ms. Ryan recommended that an additional alternative be added to the 2 chosen which would provide for the best alternative that would not require the re-channeling of the Pass. The Group determined to add this scenario to the alternatives previously chosen requiring a total of three alternatives to be evaluated. . Public Comment Doug Fee supported the examination of 3 alternatives and recommended that the Group conduct any necessary public meetings with the results of the 3 alternatives to gain public support for the final decision. David Roellig noted that the channel would need to maintain a high enough velocity to "self flush." This may require some type of structural measure to "train the channel." 4 August 12,2008 Gary McAlpin stated that all "non-structural" alternatives should be exhausted before examining "structural" alternatives. Mr. Sullivan noted that in may be advisable at this point to examine a "structural" alternative; as opposed to waiting until a later date if it is determined that "non- structural" alternatives will not provide the goal oflong-term stabilization of the Pass. It was determined to exhaust the "non-structural" alternatives before proceeding on evaluating "structural" alternatives. . Next Meeting The next meeting is scheduled for October 22, 2008. There being no further business for the good of the County, the meeting was adjourned by order of the chair at 10:42 A.M.
