The inlet channel, from the offshore ebb shoat to the bay, is approximately 6,000-ft long. Choctawhatchee bay is approximately 28 miles long and 6 miles wide, and Destin Harbor is approximately 2 miles long and ¼ mile wide. Holiday Isle separates the Harbor from the Gulf of Mexico and Norriego Point separates the Harbor from East Pass. Two rubble mound jetties protect East pass, the west jetty is approximately 3,860 ft and the east jetty is approximately 1,200 ft. The landward end of the east jetty features an approximate 330 ft rubble mound spur jetty that extends into the inlet. The spur jetty is designed to divert flow away from the eastern bank of the inlet and is currently experiencing significant scour near the tip (scour depths extending beyond - 50 ft) due to the eastward channel migration across East Pass. Area of Influence: The East Pass area of inlet influence ranges from 6,000-ft to 12,000-ft contingent on selected time period and storm events. These values are in reference to the 1999 (original) and the 2010 (updated) East Pass Inlet Management Plans. The adopted 2013 Inlet Management Implementation Plan cites “the area direct inlet impact was determined to be approximately 10,000 feet to the east and west of East Pass.” From the adopted 2013 Inlet Management Implementation Plan: “The net accretion (not including fill placement) west of the inlet between V611 and the west jetty (approximately 10,000 feet) has been approximately +6,000 cy/yr [15,000 + 26,000 = 41,000 cy/yr, less 35,000 cy/yr of fill placement]. The net erosion loss (not including fill placement) to the east of the inlet between the jetty and R27 (approximately 10,000 feet) has been approximately -54,000 cy/yr [-50,000 cy/yr - 4,000 cy/yr of fill placement].” Sediment Budget: [abbreviated version from the IMIP] The 2000 inlet management plan, based on the study by Taylor Engineering (1999), determined a net east to west longshore transport at the inlet. The 1999 sediment budget established the need to bypass 82,000 cy/yr to the west of East Pass to offset the impact of the inlet. This sediment budget was based upon a seven-year time period between 1990 and 1997 and without the benefit of beach profile data west of the inlet or bathymetric data north of the U.S. Highway 98 bridge. Due to the inherent problems with the development of the 1999 sediment budget, the adopted inlet management plan called for updating the sediment budget by the end of 2005. Previously, most researchers estimated an east to west net longshore transport in northwest Florida ranging generally between 52,000 and 91,000 cy/yr (Gorsline, 1966; Stone 1990; USAED, Mobile, 1963). However, Levin (1983) noted geological evidence of a localized eastward sediment transport at East Pass. Historically, the east end of Santa Rosa Island grew from west to east as seen by the southwest to northeast orientation of beach ridges and the eastward migration of the inlet. The 1871 survey showed the inlet migration was eastward two miles from its location today (refer to History section). Based upon wave data obtained by the Corps of Engineers, Morang (1992) suggested a drift nodal point existed at East Pass and that frequent drift reversals occurred leading to transport in both directions. The wave data collected between 1987 and 1990 revealed a predominant wave direction from the southwest. This wave direction would provide a net longshore transport to the east. Most recently, the City of Destin and the Department contracted a study by Coastal Planning and Engineering, Inc., to update the inlet sediment budget (CP&E, 2010). The study area included the entire 14-mile stretch of coast from FDEP reference monument R-1, at the west end of the beach community of Okaloosa Island, to FDEP reference monument R-50 at the east Okaloosa County line. The actual area of direct inlet impact was determined to be approximately 10,000 feet to the east and to the west of East Pass. For the time period between March 1996 and July 2007, CP&E found a change from the earlier 7-year period (1990-1997) determined in the 1999 study. Between 1996 and 2007, the trend of westward longshore transport to the west of the inlet generally continued; however, east of the inlet, the net direction of longshore transport was predominately eastward. This recent period of west to east longshore transport in the vicinity of the inlet has resulted in a small net gain immediately west of the inlet and a significant loss along Holiday Isles to the east of the inlet. Estimated annual quantity of beach quality sand reaching the updrift boundary of the improved jetty or inlet channel: 82,000 cy In the 1999 East Pass Inlet Management plan, Taylor Engineering reported that the annual net longshore sediment transport was between 58,000 and 82,000 cy. The updated 2010 Inlet Management Plan suggests volume and direction of the longshore sediment transport varies and greatly depends on dredging and storm activity. The adopted bypassing objective remains as 82,000 cy/year (minimum), as adopted in 2000. As such, the estimated quantity of beach quality sand reaching the updrift boundary of the improved inlet channel is estimate as 82,000 cy/year. Pursuant to Rule 62B-36.006(2)(a), the annual quantity of 82,000 cy of beach quality sand reaching the updrift boundary of the improved inlet channel divided by 20,000 cy per year awards 4.1 points for the “Sand Reaching the Inlet” ranking criteria. Balancing the sediment budget: Annual bypassing objective adopted by the IMP or the SMBP or as determined by a department approved study: 82,000 cy/year The annual average of bypassed material (cubic yards) since adoption of a bypass objective: 64,140 cy/year Pursuant to Rule 62B-36.006(2)(b), the annual average bypassing volume to be placed of 64,140 cy on adjacent eroding shoreline, divided by the annual bypassing objective of 82,000 cy multiplied by 20, awards 15.6 points for the “Balancing the Sediment Budget” ranking criteria. Cost effective alternatives: Unmet annual bypassing objective using material from within the inlet system: 17,860 cy/year Proposed increase in annual bypassing of material from within the inlet system: 20,000 cy/year (minimum) With reference to the September 2012 USACE hydrographic data of the East Pass Federal Navigation Channel, approximately 260,000 cy of material can be dredged and bypassed to adjacent beaches in a one-time nourishment. Upon investigation of the feasibility of alternatives (i.e. channel re-alignment or widening, sand traps, and structure configuration), the quantity of sand to be bypassed should far exceed the current yearly deficit. Again, the goal of the study is to determine methods to reduce the cost of frequent maintenance dredging within the inlet. Pursuant to Rule 62B-36.006(2)(c), the proposed annual increase in bypassing of 40,000 cy (minimum) of material within the inlet system, divided by the unmet annual bypassing of 17,860 cy, multiplied by 10, awards 10 points (maximum) for the “Cost Effectiveness” ranking criteria.
