3. Draft Objectives Reduction of average annual cost of $350,000 Reduction of average annual cost of $350,000 Maintain or improve existing water quality conditions Maintain or improve existing water quality conditions Minimize coastal impacts on GOM shoreline Minimize coastal impacts on GOM shoreline Stabilize mouth of pass to existing shoreline Stabilize mouth of pass to existing shoreline Widen pass south of Lee Callaway bridge Widen pass south of Lee Callaway bridge Narrow the pass north of the bridge/include sediment trap Narrow the pass north of the bridge/include sediment trap Place material further down drift along GOM shoreline Place material further down drift along GOM shoreline New and improve dredging efficiency thru new contract specs New and improve dredging efficiency thru new contract specs

4. Sediment Budget Model Little Lagoon is a remarkable, prolifically productive, 8 mile long (e- ), ¾ mile wide (n-s), sand dominated, brackish water coastal lake Little Lagoon is a remarkable, prolifically productive, 8 mile long (e- ), ¾ mile wide (n-s), sand dominated, brackish water coastal lake Because of national publicity, low interest loans, federal flood insurance, and a general desire to live on or near the coast, dramatic development is ongoing Because of national publicity, low interest loans, federal flood insurance, and a general desire to live on or near the coast, dramatic development is ongoing Wetlands are being damaged and destroyed and water quality is deteriorating Wetlands are being damaged and destroyed and water quality is deteriorating Nutrients and Fecal coli form measurements are up over the last 10- 15 years and other pollutants are almost certainly on the rise Nutrients and Fecal coli form measurements are up over the last 10- 15 years and other pollutants are almost certainly on the rise Little Lagoon circulation and turnover are poor and pollutant resident times are lengthy Little Lagoon circulation and turnover are poor and pollutant resident times are lengthy Nutrients accumulate and we are suspicious that conditions are ideal for phytoplankton “blooms” Nutrients accumulate and we are suspicious that conditions are ideal for phytoplankton “blooms”

Barney and Dennis Preference-F Barney and Dennis Preference-F Expense problem with options A, B, C, D, concrete seawall, loss of public gathering Expense problem with options A, B, C, D, concrete seawall, loss of public gathering ALT C, E, F increase tidal prism 11%, 13%, 56% respectively compared to baseline ALT C, E, F increase tidal prism 11%, 13%, 56% respectively compared to baseline ALT C, F decrease channel shoaling from ~29,000 yds to ~21,000 yds (C), and ~12,000 yds (F) ALT C, F decrease channel shoaling from ~29,000 yds to ~21,000 yds (C), and ~12,000 yds (F) ALT F model predicts more flood and ebb tidal delta shoaling ALT F model predicts more flood and ebb tidal delta shoaling ALT F has smallest predicted annualized cost over 50 years, less than ½ of baseline and ALT C, and ALT E ALT F has smallest predicted annualized cost over 50 years, less than ½ of baseline and ALT C, and ALT E Up front investment- ~$2MM (C), ~$130K (E), ~526K (F) Up front investment- ~$2MM (C), ~$130K (E), ~526K (F)

Closing Comments Closing Comments LLPS has stated intent to not object to modification of court order to move sand further down beach LLPS has stated intent to not object to modification of court order to move sand further down beach LLPS expresses no current objections to plans to redesign pass and utilize sands for repair west of pass, we like option F? LLPS expresses no current objections to plans to redesign pass and utilize sands for repair west of pass, we like option F? LLPS will work with ALDOT on additional court order modifications-trigger language and process, shoal sand maintenance procedures, and depth requirements in maintenance phase of court order LLPS will work with ALDOT on additional court order modifications-trigger language and process, shoal sand maintenance procedures, and depth requirements in maintenance phase of court order Currently ALDOT is awaiting city draft language for court order which would allow dredge spoil placement further west of the pass than allowed by current court order Currently ALDOT is awaiting city draft language for court order which would allow dredge spoil placement further west of the pass than allowed by current court order City has not yet obtained required permits from COE, ADEM, FWS City has not yet obtained required permits from COE, ADEM, FWS
