Vigu=s "8" Beach Homeowners Association Page 2 9. PROJECT DESCRIPTION 10/19/92 Figure 118" Island is a barrier island located in the northeast corner of New Hanover County. The project site is the ocean beach and the shoaled areas of the navigable waters, both adjacent to the northern Inlet Hazard Area of the Island (Rich Inlet). The applicant proposes to dredge the recently accumulated sand material in Nixon's Channel, and use the material to renourish the more vulnerable section of the residential beach. Figure 118" Island is classified as Conservation in the New Hanover County Land Use Plan. The adjacent waters are the Atlantic Ocean to the east, and Middle Sound to the west. Middle Sound is classified SA - ORW by the Division of Environmental Management, is a designated Primary Nursery Area, and is open to the taking of shellfish. The applicant claims an erosion loss of 3' - 10' per year in the project area. The aerial photography confirms this for the Inlet Hazard Area. However, the current Coastal Management Erosion Rate Maps show a 2' per year erosion rate for the beach area adjacent to the Inlet Hazard Area. The applicants are proposing to dredge the shoaled area behind the north end of the island. This shallow area is located in the main navigation channel. The shoal has formed since the 1985 aerial photography, paralleling the configuration of the island at this point. The bottom material here appears to be composed primarily of sand, rather than more productive material. The project area is approximately 2800' x 4001, or 1,120,000 square feet (25.7 acres). The proposed depth is -9' mean low water. The average depth of the area proposed for dredging is -3' mlw. The adjacent waters connecting to the Atlantic Ocean average -9' mean low water. The dredging is to be accomplished hydraulically, and the material placed on the ocean beach. Because of the proximity to the inlet, this area of the beach suffers rapid erosion. The erosion maps indicate a loss of 2' per year; however, this takes into account the previous renourishment efforts. The area underwent a large scale renourishment in 1988, with subsequent American Beachgrass plantings. It was renourished prior to that in 1984. Hence, the stated erosion rates may give a false impression. Approximately 274,000 cubic yards of material will be pumped from the estuarine bottom to the beachfront, and placed along approximately 3,000 linear feet of shoreline. The material will then be bulldozed to a profile mimicking the natural profile. The final elevation of the pushed dunes will be approximately 7' mean sea level, extending in width approximately 1151. The remaining material will be pushed to a point ending at approximately -2' mean sea level. The slope of this area will be 20/1. During the dredging process, there will be a temporary berm constructed to control effluent. There are enclosed material compatibility studies performed in the dredge area and the renourishment area. The dredge material is described as medium to fine sand. The material on the beach currently should be, for the most part, that placed in this area during prior renourishment projects. The grain size study does show similar size and material composition. With sieve sizes 50, 80, 100, and 200, there was little consistency between the two sample sites of the beach itself. Figure "8" Beach Homeowners Association Page 3 9. PROJECT DESCRIPTION - Continued: The areas in which there appear to be considerable differences between the dredge material and the beach material occur with sieve 150, and #100. Sieve #100 would indicate that there is a finer material on beach site 2 currently than that to be placed. Sieve #50 would indicate a finer sand in the dredge material than on beach site 1. The area proposed for dredging was dredged in 1984, and an adjacent area in 1988, both to the proposed depth of -6'mlw. The area proposed for renourishment was renourished in 1984 to all but the northernmost 3001. It was renourished in 1988 except for the northernmost 350' - 4001, and the southern 1200' (approximately). 10. ANTICIPATED IMPACTS Under the proposal, approximately 274,000 cubic yards of material would be dredged from Rich Inlet. This area has been dredged twice in the last ten years, and photography indicates that it has recently shoaled. The depth has been proposed and dredged to -6'mlw in the past. The current proposal is for -9'mlw. The adjacent area and connecting waters average -91mlw before joining the waters of the Atlantic Ocean. Though the depth is probably not essential to the navigability of the area, there should be no water quality concerns from the proposed depth. The material will be placed on the beachfront, and contained behind a temporary berm to control effluent. The material will be formed to follow the natural contour. It will extend to a point 2' below mean sea level. Compatibility studies show that there will be more fines in the dredge material than beach site 1 using sieve #50. With sieve #80 & #100, the indication at this level is more fines on beach site 2 than in the dredge material. This study would show that for the most part, the dredge material will be similar or larger in size than the present beach sand.

AND St P we FIGURE EIGHT ISLAND BEACH RENOURISHMENT (NORTH END) Background DIVA; , ! OF COASTk.L fv??, ?{,GEfv'iE r:? Over the years the small boat and navigation access channel approaching Rich Inlet from the Atlantic Intracoastal Water (AIWW) has shoaled badly, making navigation dangerous. Cor- respgndingly, the ocean front at the north end of Figure Eight Island adjacent to Rich Inlet has suffered an accelerated rate of erosion, depleting material on the open beach and seriously erod- ing the primary dunes on the upper beach in this area. CAMA per- mits authorizing maintenance dredging of the Rich Inlet access channel and placement of the dredged material on the ocean beach as renourishment of the sand beach have been issued twice in the recent past (CAMA Permit Nos. 89-83 (4 April 1984) and 21-88 (20 January 1988). Unfortunately, the latest permit was permitted to expire without a request for renewal, necessitating this applica- tion for a similar re-authorization. Proiect Description It is proposed to dredge extensive sub-tidal shoal areas in the generally open water area behind Rich Inlet which connects to the AIWW. The primary shoal within the inlet proper has con- tinued to grow to form a protective spit which has welded itself to the north beach on Figure Eight Island. Correspondingly, a good, natural deep water channel currently exists on the north shoulder of the inlet shoal between the inlet ebb tide delta and the open water areas of the Rich Inlet connecting channel to the AIWW. However, behind the inlet shoal, extensive additional sub- tidal shoaling has taken place that interferes with safe naviga- tion of this normally appearing open water area. (This is clearly evident from the hydrographic survey transects shown on Sheet 2 of the application sketches (proposed dredge sections are plotted on Sheet 2A). The shoal patterns are also reflected in the aerial photographs of the inlet.) It was determined that it would be more beneficial to improve the overall access channel area than to attempt any dredging of the major protective inlet shoal which has formed as described above and ds seen in the photographs. (Note: The changes in the inlet shoal areas be- tween the May 1990 photo and the July 1992 photos are clearly ap- parent. ;While there are portions of this major shoal area that are sub-tidal and might be dredged, it was determined that the overall benefits of leaving that shoal area intact and reducing the sub-tidal shoals in the approach water behind the inlet would be more beneficial to the interests of all concerned.) All of the sand materials r6moved from the Rich Inlet approach channel area will be discharged along approximately 3,000 linear feet of beachfront, extending from an optimum point on the north shoulder of the island southward to its terminus. A (Modified 3 September 1992) • . transition adapted to the existing beach profile with a transi- tion section 300 to 400 feet long will be provided at both ends of the beach fill. The basic dimensions of the beach fill will be to an elevation of approximately 7 feet mean sea level (MSL) with a berm width of approximately 115 feet, with the remainder of the materials shaped to an approximate 20 to 1 slope between Elevation 7 and -2.0 feet MSL (see Sheets 1 and 3 of the permit application sketches for beach fill location and simple proposed beach profile sketch). It is estimated that approximately 274,000 cubic yards of medium to fine sand materials will be ex- cavated from the proposed area to be dredged by hydraulic pipeline dredge. The material will be transported by the dredge pipeline and deposited along the beachfront, using a temporary protective berm parallel to the shoreline to control the effluent runoff, insuring maximum upland beach deposition of the material and minimizing of turbidities within the surf zone. Test borings and sand samples were taken along the length of the proposed channel maintenance dredging areas and on the ocean beach as shown on Sheets 1 and 2. Sampling and testing were done by an independent geotechnical agent with samples extracted from the near-bottom area with a second sample taken from the soil column near the maximum depth of proposed excavation (to -9 feet MLW). A grain size analysis of the materials sampled is attached hereto. It will be noted that there is reasonable compatibility be- tween the insitu beach sand and that to be excavated from the sound areas behind the island. Most notably, the percentages of material ranging between .180 and .260 millimeters (mm)(sieve sizes Nos. 80 and 50, respectively) are certainly useful for placement on the beach. Both the borrow material and the natural beach sand contain a slightly higher percentage of "fines" (material passing the No. 200 sieve) than is considered ideal. A grain size distribution analysis reveals a median grain size rang- ing from 0.25 to 0.27 mm, which is considered suitable for beach renourishment. (Note beach sand sample #2 is an anomaly that reveals an average grain size of only 0.17 mm on analysis.) The relatively small quantity of fine material involved, in any case will be quickly sorted by daily tidal processes and the limited turbidity resulting therefrom should dissipate within a few days. (It is'also pointed out that this work will be done during the winter'.season, and public use and any environmental impacts should 'be minimal.) The proposed beach renourishment will help combat normal annual erosion of the beach and improve a large amount Of the foreshore area for recreational use. 9Ep 1YY2 DIVA COASTAL N (Modified 3 September 1992) • PL Ul JLAti Ia ,. ?n Z `` AL ' O ` C?IVl7L ; ' "D ru_ &TUL r 0 N lC 'rut , cn m VrL CAP) Cn m 0 All /920 ??' /o 7 t 'j r- WAS.
