BOX 1890 WILMINGTON, NORTH CAROLINA 28402.1890 March 22, 1990 IN REPLY REFER TO Planning Division Dr. George T. Everett, Director Division of Environmental Management North Carolina Department of Environment, Health, and Natural Resources Post Office Box 27687 Raleigh, North Carolina 27611-7687 Dear Dr. Everett: The purpose of this letter is to request amendment of Water Quality Certification'`(-WQC) Nos. 1393 issued on April 30, 1980, and 1393-R issued on? ' September 30, 1980. Certification No. 1393 allowed the discharge of dredged material for the Wrightsville Beach' Restoration. Project, which extended 14,000 feet.from Masonboro Inlet on the south to the location of the northern town limit as it existed in 1965 (Station 70+00 to Station 140+00 on the enclosed plates 1 and 2). Certification No. 1393-R modified WQC No. 1393 to allow discharge of dredged material from the 114,000-foot mark (Station 140+00) of Wrightsville Beach to the north approximately 2,000 feet (Station 160+00). The beach renourishment limits have not changed since 1980; however, WQC Nos. 13,93 and 1393-R were written only for the work to be performed in 1980, and the borrow sources for the renourishment material have been expanded. We_request that WQC Nos. 1393 and 1.393-R be amended to include continued Federal participation in the Wrightsville Beach Shore and Hurricane Wave Protection Project, New Hanover County, North Carolina, and the discharge of dredged material from the expanded sediment trap/borrow sites in Banks Channel and Masonboro Inlet on Wrightsville Beach in any year that it may be required. To facilitate your review of our request for amendment, I have enclosed the following documents: _ a. Section 404(b)(1) (P.L. 95-217) Evaluation Report and Findings of Compliance signed on October 4, 1982. < -2- b. Public Notice CESAW-PD-E-90-65-0009, dated February 1, 1990. c.

Amendment to the Supplement to the EA_/FONSI, prepared in March 1990. As we would like to begin renourishment in July 1990, we would appreciate receiving the amendment prior to the scheduled advertisement date of May 14, 1990.

PROJECT DESCRIPTION Renourishment of Wrightsville Beach is scheduled to be performed in the late spring and early summer 1990. Approximately 580,000 cubic yards of sandy material will be placed on the beach between stations 70+00 and 160+00 as shown on plates 1 and 2. The Masonboro Inlet and Banks Channel sediment trap/borrow areas will again be used for the 1990 renourishment. The borrow areas have been expanded to include an area approximately 1,250 feet long by 875 feet wide at the confluence of Banks Channel and the Masonboro Inlet Channel and an area approximately 600 feet long by 600 feet wide at the eastern end of the Masonboro Inlet Channel. The total borrow area is shown on plate 3. The material within the, sediment trap/borrow areas consists of high quality beach sand which enters the system from Masonboro Inlet and is suitable for placement on the beach. The work will be accomplished by the use of a hydraulic pipeline dredge selected by competitive bidding. No related dredging and beach disposal conducted by others is anticipated. The discharge of fill material on Wrightsville Beach is covered under Water Quality Certification Nos. 1393, issued on April 30, 1980, and 1393-R, issued on September 30, 1980. The Section 404(b)(1) Evaluation and Findings of Compliance for the project were completed and signed on March 28, 1980, as amended on August 7, 1980, and October 4, 1982. The expansion of the borrow areas,'shown on plate 3, does not alter the findings in the Section 404(b)(1) Evaluation Report and Finding of Compliance. The proposed action is discussed in the Environmental Assessment and Finding of No Significant Impact (EA/FONSI) for the Continued Federal Participation in the Wrightsville Beach Shore and Hurricane Wave Protection Project, New Hanover County, North Carolina, which is included in the Feasibility Report dated September 1982, and in the Supplement to the EA/FONSI, signed on August 22, 1989, which is contained in the Wrightsville Beach, North Carolina, Renourishment Report dated September 1989. A copy of the Supplement to the EA/FONSI which was signed on August 22, 1989, may be obtained by writing to Ms. Trudy Wilder, Environmental Resources Branch, Wilmington District, Post Office Box 1890, Wilmington, North Carolina 28402-1890. The proposed action is within the 100-year flood plain and has been evaluated for adherence to the requirements of Executive Order 11988. The action restores beaches and dunes and helps to minimize the impacts of floods on human safety, health, and welfare. The only other alternative is no action. In order to provide beach restoration for the authorized project, the fill material must be located in the flood plain. The proposed project conforms to applicable state and local flood plain protection standards. The proposed action has been evaluated under Executive Order 11990, Protection of Wetlands. The work will not require dredging or filling of any wetlands. The discharge pipeline may cross wetlands to reach the disposal site. Where the pipeline crosses wetlands, pipeline joints will be properly sealed to provide protection against leakage. Any impacts to wetlands will be minor and of short duration. No impacts to endangered species are expected if beach disposal occurs between November 16 and April 30. However, work to be performed between May 1 and November 15 could impact nesting loggerhead or green sea turtles, species protected by the Endangered Species Act of 1973, as amended. If dredged material is discharged on the beach during the turtle nesting season, daily monitoring of sea turtle nesting efforts in the beach impact area and nest relocation, as needed, will be performed in order to minimize potential adverse impacts to these species. Also, the hatching success of all nests in the project area will be monitored. This work has been coordinated with the U.S. Fish and Wildlife Service and the N.C. Wildlife Resources Commission. Formal consultation with the U.S. Fish and Wildlife Service has been completed regarding the potential impacts of beach disposal on wintering piping plovers and transient roseate terns and to allow replacement of fill material on the beach during the sea turtle nesting season in 1990 and during future renourishment events, if it becomes necessary. The biological opinion received on December 21, 1989, states that the project will have no effect on piping plovers and roseate terns and is not likely to jeopardize the continued existence of the loggerhead and green sea turtles. No impacts to known archaeological/historical resources will occur. The proposed action is consistent with the approved Coastal Management Program of the State of North Carolina (N.C. Division of Coastal Management letter dated September 17, 1982). The Supplement to the EA/FONSI which was signed on August 22, 1989, amended our consistency determination of July 28, 1982, to include the expansion of the sediment trap/borrow areas. A request for concurrence/no:iconcurrence with our amendment has been sent to the N.C. Division of Coastal Management (U.S. Army Corps of Engineers letter to State Clearinghouse, August 23, 1989). 2 4 Attached is a list of Federal, State, and local agencies with whom this activity is being coordinated. The decision whether to perform this work will be based on an evaluation of the probable impact, including cumulative impacts of the proposed activity on the public interest. That decision will reflect the national concern for both protection and utilization of important resources. The benefits which reasonably may be expected to accrue from the proposal must be balanced against its reasonably foreseeable detriments. All factors which may be relevant to the proposal will be considered, including the cumulative effects thereof; among those are conservation, economics, aesthetics, general values, flood hazards, flood plain values, land use, navigation, shoreline erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, considerations of property ownership, and in general, the needs and welfare of the people. Any person who has an interest which may be affected by the disposal of this dredged material may request a public hearing. The request must be submitted in writing to the District Engineer within 30 days of the date of this notice and must clearly set forth the interest which may be affected and the manner in which the interest may be affected by this activity. In order for such a request to be given appropriate consideration, it should be mailed or delivered to the U.S. Army Engineer District, Wilmington, Post Office Box 1890, Wilmington, North Carolina 28402-1890, in time to be received on or before March 5, 1990.

PURPOSE AND NEED FOR THE PROPOSED ACTION. This document supplements the Environmental Assessment and Finding of No Significant Impact (EA/FONSI) for. the Continued Federal Participation in the Wrightsville Beach Shore and Hurricane Wave Protection Project, New Hanover County, North Carolina, which is included in the Feasibility Report dated September 1982. As a result of the feasibility report, the Wrightsville Beach project was reauthorized by the Water Resources Development Act of 1986 (P.L. 99-662) to extend Federal cost sharing for beach nourishment for the life of the project. The study area is shown on Figure 1. The purpose of this supplement to the EA/FONSI is to assess the impacts of expanding the Masonboro Inlet/Banks Channel sediment trap/borrow areas and placing the material from these areas on Wrightsville-Beach. All other impacts of the project are addressed in the EA/FONSI referenced in the previous paragraph and will not be repeated herein. Expanding the two sediment trap/borrow areas is necessary to increase the amount of suitable borrow material available for renourishment of Wrightsville Beach during the FY 90 renourishment event and during future nourishment events. 2. PROPOSED ACTION. The Masonboro Inlet and Banks Channel sediment trap/borrow areas will be expanded to include an area approximately 1,250 feet long by 875 feet wide at the confluence of Banks Channel and the Masonboro Inlet Channel and an area approximately 600 feet long by 600 feet wide near the seaward end of the Masonboro Inlet South Jetty as shown on Plate 3. The Banks Channel sediment trap/borrow area, including the 1,250 foot by 875 foot expansion, is referred to as Borrow Area B and is dredged to a depth of -30 feet mean-low-water (mlw). The Masonboro Inlet sediment trap/borrow area is divided into two sections, Borrow Areas A and A' and is dredged to a depth no greater than -20 feet mlw to avoid impacts to existing archeological/historical resources. ° The 600 foot by 600 foot expansion is located at the eastern end of Borrow Area A'. 3. ENVIRONMENTAL EFFECTS. The discussion concerning the environmental effects of the expansion of the sediment trap/borrow areas on affected resources are the same as those described in the previous-'y referenced EA/FONSI except as stated below: a. Water Quality. The material within the sediment trap/borrow areas consists of high quality beach sand which enters the system from Masonboro Inlet and is suitable for placement on the beach. The discharge of fill material on Wrightsville Beach is covered under water quality certifications number 1393 issued April 30, 1980, and number 1393-R issued September 30, 1980. The Section 404(b)(1) Evaluation Report and Finding of Compliance for the project are included as Appendix G of the Feasibility Report and EA/FONSI, dated September 1982. The expansion of the areas does not alter the findings in the Section 404(b)(1) Evaluation Report and Finding of Compliance. These documents will, therefore, not require revision. b. Archeological/Historical Resources. The expansion of the sediment trap/borrow areas has been reviewed for archeological/historic concerns. The magnetic surveys of Masonboro Inlet, Masonboro Channel, and Banks Channel, condLicted in the late 1970's, indicate that no effect to known cultural resources will occur in the expansion areas, as long as the Masonboro Inlet sediment trap/borrow areas are not dredged below -20 feet mlw. A magnetic anomaly was identified in'Masonboro Inlet area at -25 feet mlw. No cultural resources were identified in the Banks Channel sediment trap/borrow area, Borrow Area B, during the survey. c. Coastal Management Program. The expansion of the sediment trap/borrow areas is consistent with the approved Coastal Management Program of the State of North Carolina. This supplement revises the existing consistency determination (Appendix F of the Feasibility Report and EA/FONSI, 1982) dated July 28, 1982. State concurrence was received on September 17, 1982. d. Endangered Species. The expansion of the sediment trap/borrow areas will not jeopardize endangered species 4r their critical habitat or violate the protective measures for any marine sanctuaries. Reinitiation of formal consultation with the U.S. Fish and Wildlife Service has been requested to include the potential impacts of beach disposal on wintering piping plovers and transient roseate terns, and to allow placement of fill material on the beach during the sea turtle nesting season in 1990 and during future renourishment events, if it becomes necessary. 2 4. COORDINATION. Agencies Contacted. Representatives from the following agencies were contacted regarding the proposed action: U.S. Fish and Wildlife Service, Raleigh, North Carolina Mayor, Town of Wrightsville Beach Notice of Availability. A notice of the availability of the Supplement to the EA/FONSI will be mailed to all concerned Federal, State, and local agencies and the public. 5. FINDING OF NO SIGNIFICANT IMPACT. The proposed expansion of the sediment trap/borrow areas will no- significantly affect the quality of the human environment; therefore, an environmental impact statement will not be prepared. /L-b) ?1' ence W.

RENOURISHMENT PROJECT CESAW-PD-E-90-65-0009 February 1, 1990 TO WHOM IT MAY CONCERN: THE WILMINGTON DISTRICT, CORPS OF ENGINEERS, Wilmington, North Carolina, is preparing to renourish Wrightsville Beach, New Hanover County, North Carolina. PROJECT DESCRIPTION Renourishment of Wrightsville Beach is scheduled to be performed in the late spring and early summer 1990. Approximately 580,000 cubic yards of sandy material will be placed on the beach between stations 70+00 and 160+00 as shown on plates 1 and 2. The Masonboro Inlet and Banks Channel sediment trap/borrow areas will again be used for the 1990 renourishment. The borrow areas have been expanded to include an area approximately 1,250 feet long by 875 feet wide at the confluence of Banks Channel and the Masonboro Inlet Channel and an area approximately 600 feet long by 600 feet wide at the eastern end of the Masonboro Inlet Channel. The total borrow area is shown on plate 3. The material within the sediment trap/borrow areas consists of high quality beach sand which enters the system from Masonboro Inlet and is suitable for placement on the beach. The work will be accomplished by the use of a hydraulic pipeline dredge selected by competitive bidding. No related dredging and beach disposal conducted by others is anticipated. The discharge of fill material on Wrightsville Beach is covered under Water Quality Certification Nos. 1393, issued on April 30, 1980, and 1393-R, issued on September 30, 1980. The Section 404(b)(1) Evaluation and Findings of Compliance for the project were completed and signed on March 28, 1980, as amended on August 7, 1980, and October 4, 1982. The expansion of the borrow areas, shown on plate 3, does not alter the findings in the Section 404(b) (1) Evaluation Report and Finding of Compliance. The proposed action is discussed in the Environmental Assessment and Finding of No Significant Impact (EA/FONSI) for the Continued Federal Participation in the Wrightsville Beach Shore and Hurricane Wave Protection Project, New Hanover County, North Carolina, which is included in the Feasibility Report dated September 1982, and in the Supplement to the EA/FONSI, signed on August 22, 1989, which is contained in the Wrightsville Beach, North Carolina, Renourishment Report dated September 1989. W _1-1 F V. A copy of the Supplement to the EA/FONSI which was signed on August 22, 1989, may be obtained by writing to Ms. Trudy Wilder, Environmental Resources Branch, Wilmington District, Post Office Box 1890, Wilmington, North Carolina 28402-1890. The proposed action is within the 100-year flood plain and has been evaluated for adherence to the requirements of Executive Order 11988. The action restores beaches and dunes and helps to minimize the impacts of floods on human safety, health, and welfare. The only other alternative is no action. In order to provide beach restoration for the authorized project, the fill material must be located in the flood plain. The proposed project conforms to applicable state and local flood plain protection standards. The proposed action has been evaluated under Executive Order 11990, Protection of Wetlands. The work will not require dredging or filling of any wetlands. The discharge pipeline may cross wetlands to reach the disposal site. Where the pipeline crosses wetlands, pipeline joints will be properly sealed to provide protection against leakage. Any impacts to wetlands will be minor and of short duration. No impacts to endangered species are expected if beach disposal occurs between November 16 and April 30. However, work to be performed between May 1 and November 15 could impact nesting loggerhead or green sea turtles, species protected by the Endangered Species Act of 1973, as amended. If dredged material is discharged on the beach during the turtle nesting season, daily monitoring of sea turtle nesting efforts in the beach impact area and nest relocation, as needed, will be performed in order to minimize potential adverse-impacts to these species. Also, the hatching success of all nests in the project area will be monitored. This work has been coordinated with the U.S. Fish and Wildlife Service and the N.C. Wildlife Resources Commission. Formal consultation with the U.S. Fish and Wildlife Service has been completed regarding the potential impacts of beach disposal on wintering piping plovers and transient roseate terns and to allow replacement of fill material on the beach during the sea turtle nesting season in 1990 and during future renourishment events, if it becomes necessary. The biological opinion received on December 21, 1989, states that the project will have no effect on piping plovers and roseate terns and is not likely to jeopardize the continued existence of the loggerhead and green sea turtles. No impacts to known archaeological/historical resources will occur. The proposed action is consistent with the approved Coastal Management Program of the State of North Carolina (N.C.

The decision whether to perform this work will be based on an evaluation of the probable impact, including cumulative impacts of the proposed activity on the public interest. That decision will reflect the national concern for both protection and utilization of important resources. The benefits which reasonably may be expected to accrue from the proposal must be balanced against its reasonably foreseeable detriments. All factors which may be relevant to the proposal will be considered, including the cumulative effects thereof; among those are conservation, economics, aesthetics, general values, flood hazards, flood plain values, land use, navigation, shoreline erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, considerations of property ownership, and in general, the needs and welfare of the people.

Certification No. 1393 allowed the discharge of dredged material for the Wrightsville Beach Restoration Project which extended 14,000 feet from Masonboro Inlet on the south to the location of the northern town limit as it existed in 1965 (Station 70+00 to Station 140+00 on the enclosed plates 1 and 2). Certification No. 1393-R modified WQC No. 1393 to allow discharge of dredged material from the 14,000-foot mark (Station 140+00) of Wrightsville Beach to the north approximately 2,000 feet (Station 160+00). The beach renourishment limits have not changed since 1980; however, WQC Nos. 1393 and 1393-R were written only for the work to be performed in 1980, and the borrow sources for the renourishment material have been expanded. We request that WQC Nos. 1393 and 1393-R be amended to include continued Federal participation in the Wrightsville Beach Shore and Hurricane Wave Protection Project, New Hanover County, North Carolina, and the discharge of dredged material from the expanded sediment trap/borrow sites in Banks Channel and Masonboro Inlet on Wrightsville Beach in any year that it may be required. To facilitate your review of our request for amendment, I have enclosed the following documents: VW _ a.

SECTION 404(b) (PL 95-217) EVALUATION REPORT CONTINUED FEDERAL PARTICIPATION IN THE WRIGHTSVILLE BEACH SHORE AND HURRICANE WAVE PROTECTION PROJECT NEW HANOVER COUNTY, NORTH CAROLINA I. PROJECT DESCRIPTION a. Location. Wrightsville Beach, New Hanover County, North Carolina. b. Gegeral Description. The authorized project consists of a dune with a landward toe at or near the town building line, with a crown width of 25 feet at an elevation of 15 feet above mean low water (MLW) and a 50-foot-wide berm at an elevation of 12 feet above MLW. The project extends 14,000 feet from Masonboro Inlet on the south to the location of the northern town limit existing in 1965. Initial construction included the closure of Moore Inlet, which previously separated Wrightsville Beach from Shell Island to the north, and placement of advance nourishment al.ong 2,700 feet of beach north of the authorized project limit. The current proposal. is to continue Federal participation in maintaining this project, as original authorization provided for only 10 years of Federal involvement after original project construction. As erosion of the existing project is attributabl.e to two sources, natural erosion (53.8%) and erosion caused by the jetties at Masonboro Inlet (46.2%), the costs of maintaining the project will be divided accordingly. The Federal Government will bear 100% of the project maintenance costs attributable to erosion induced by the navigation project at Masonboro Inlet, while the project maintenance costs associated with natural erosion will be cost shared with the local project sponsor (Town of Wrightsville Beach) according to terms laid out in the authorizing document (50% Federal, 50% local). Erosion of the shore and hurricane wave protection project at Wrightsville Beach occurs at a rate of 130,000 cubic yards (cu. yds.) per year. Nourish- ment of the project will occur once every two years; therefore, approximate- ly 260,000 cu. yds. of sand will be placed with each nourishment event. In order to avoid dredging and disposal during periods of high biological and recreational activity, nourishment work will be performed during the established dredging window (October through March). Two borrow areas will be used to obtain the nourishment material. These borrow areas were used previously during the reconstruction of the project which occurred during the winter of 80/81. One area is located in Banks Channel between Masonboro Inlet and Channel Marker 14. This site will be G-1 . r dredged to a plane of -30 feet mean low water (MLW) during maintenance events. The other area is located in Masonboro Inlet. The Masonboro Inlet site will only be dredged to a depth of -20 feet MLW in order to avoid impacting submerged cultural resources. The boundaries of both of these sites can be seen on plate 1. Material excavated by the dredge in the borrow areas will be pumped through a submerged pipeline in Banks Channel and, with the aid of a floating booster station, transported to the beach. Short sand dikes will be used on the beach to delay the return of the effluent to the ocean. This will aid in the retention of sand and reduce the amount of turbidity introduced into the surf zone. Bulldozers will be used for spreading and shaping the sand placed on the beach. C. Authority and Purpose. Authorization of the existing Wrightsville Beach, NC, project was provided by Public Law 84-874, 87th Congress, H. R. 13273 23 October 1962 (House Document 511, 87th Congress, 2nd session). The authority for this study is contained in a resolution of the Committee on Public Works of the U.S. House of Representatives, dated 2 December 1970. The resolution was initiated by Congressman Alton Lennon, and requested the Secretary of the Army to direct the Office of the Chief of Engineers to make a survey of "Wrightsville Beach, North Carolina, and adjacent beaches in the interest of beach erosion control, hurricane protection and related purposes, including oceanic and lagoonal shores and interconnected tidal channels." d. General Description of Dredged or Fill Material. (1) General Characteristics of Material: The material to be discharged is predominantly sand, with minor amounts of shell fragments and silt and/or clay. (2) Quantity of Material: Approximately 260,000 cubic yards of material will be discharged during 'each maintenance event. (3) Source of Material: The material proposed for discharge is naturally occurring sands which have been deposited in Banks Channel and Masonboro Inlet. e. Description of the Proposed Discharge Site. (1) Location: The location of the discharge site is shown on figure 1. (2) Size: The discharge area extends northward from Masonboro Inlet 16,700 feet (14,000 feet project length,.,,;,,,,700 feet transition). f" 2 G-2 % (3) Type of Site: The discharge will be on the beach at Wrightsville Beach, NC. (4) Type of Habitat: Beachfront and nearshore ocean habitat will be affected. * (5) Timing and Duration of Discharge: Discharge will occur approximately once every two years for the project life. The discharges will occur between 1 October and 31 March. f. Description of Disposal Method. Sand will be pumped from the borrow sites and discharged onto the beach by a pipeline dredge. Short sand dikes will be used on the beach to delay the return of the effluent to the ocean. Bulldozers will be used for spreading and shaping the sand placed on the beach. II. FACTUAL DETERMINATIONS a. Physical Substrate Determinations. (1) Substrate Elevation and Slope: All of the discharged material will be placed on the beach and will decrease the bathymetry of the area. (2) Sediment Type: Material placed on the beach will be similar to that which is covered. (3) Dredged/Fill Material Movement: Material placed on the beach will be subject to normal wave action and will undergo substantial movement. (4) Physical Effects on Benthos: Benthic populations on the beach will be disrupted by the discharge. Populations should reestablish quickly as the new substrate will be similar in nature to that which existed prior to the discharge. (5) Other Effects: Not applicable. (6) Actions Taken to Minimize Impacts: None. b. Water Circulation, Fluctuation, and Salinity Determinations. (1) Water: (a) Salinity. No effect. (b) Water chemistry. No effect. (c) Clarity. Some turbidity may result from deposition of sand; however, due to the coarseness of the material, this effect is expected to be limited. *If beach renourishment occurs after May 1 of any year, a sea turtle monitoring program will be enforced. 3 G-3 I -P (d) Color. No effect. (e) Odor. Not applicable. (f) Taste. Not applicable, (g) Dissolved Gas Levels. Not applicable. (h) Nutrients. No effect. (i) Eutrophication, No effect. (j) Others as Appropriate. Not applicable. (2) Current Patterns and Circulation: (a) Current Patterns and Flow. No effect. (b) Velocity. No effect. (c) Stratification. No effect. (d) Hydrologic Regime. No effect. (3) Normal Water Level Fluctuations: No effect. (4) Salinity Gradients: No effect. (S) Actions That Will Be Taken to Minimize Impacts: None. c. Suspended Particulate/Turbidity Determinations. (1) Expected Changes in Suspended Particulates and Turbidity Levels in Vicinity of Disposal Site: Little turbidity should be associated with project maintenance as the disposal material will be principally coarse sand taken from Masonboro Inlet and Banks Channel. Previous nourishment events using materials from this location have not produced significant turbidity levels. Column: (2) Effects on Chemical and Physical Properties of the Water (a) Light penetration. Reduction in light penetration should be slight as turbidity levels are expected to be low. (b) Dissolved Oxygen. No significant effect. (c) Toxic Metals and Organics. Not applicable. (d) Pathogens. Not applicable. A- 4 G-4 e 41, (e) Esthetics. Turbidity will not be of sufficient magnitude to detract from the esthetics of the area. (f) Other. Not applilcable. (3) Effects on Biota: (a) Primary production, photosynthesis. Effects should be slight, as turbidity levels will be low. (b) Suspension/filter feeders. Deposition of sands will disturb sedentary organisms occurring in the disposal site. Effects of 'turbidity are expected to be slight. (c) Sight feeders. Turbidity is not expected to be serious enough.to significantly affect sight feeding organisms. . (4) Actions Taken to Minimize Impacts: Short sand dikes will be used.to delay the return of effluent to the surf zone. d. Contaminant Determinations. Due to the coarseness of the material to be disposed and the fact that it is from noncontaminated sources, deposition will not introduce, relocate, or increase contaminants. e. Aquatic Ecosystem and Organism Determinations. (1) Effects on Plankton: Effects should be slight, as turbidity levels will be low. (2) Effects on Benthos: Benthic communities within the project area will be disrupted with each nourishment event. Due to the similarity of the fill material to that already occurring on the beach, reestablishment of stable benthic communities should occur rapidly after each nourishment -event. (3) Effects on Nekton: No significant adverse impacts on nekton are anticipated, as losses of benthic organisms will be temporary. (4) Effects on Aquatic Food Web: Temporary disturbance of benthic communities will disrupt energy flow from lower to higher trophic levels. This impact. will be limited in scope and duration, and is not considered significant. (5) Effects on Special Aquatic Sites: (a) Sanctuaries and refuges. Not applicable. (b) Wetlands. No wetlands will be affected by the proposed discharge. 5 G-5 V (c) Mud flats. Not applicable. (d) Vegetated shallows. Not applicable. (e) Coral reefs. Not applicable. (f) Riffle and pool communities. Not applicable. *(6) Threatened and Endangered Species: A "no effect" determination has been reached through the biological assessment process. (7) Other Wildlife: Wildlife of the beachfront should be unaffected. (8) Actions to Minimize Impacts: None. f. Proposed Disposal Site Determination. (1) Mixing Zone Determination: The mixing zone will be minimal due to the coarse and uncontaminated nature of the material to be deposited. ** (2),.Determination of Compliance with Applicable Water Quality Standards: LA Section 401 Water Quality Certificate has been applied for from the State of North Carolinas (3) Potential Effects on Human Use Characteristics: (a) Municipal and private water supply. No effect. (b) Recreational and commercial fisheries. Fishing should be unaffected by the project due to the minor affects on natural resources and the timing of the disposal activities. (c) Water related recreation. Recreation should be enhanced by the project, as the existing heavily used beach will be kept from eroding. Since disposal will be performed during the off-season (October through March), direct impacts on beach goers will be limited. (d) Esthetics. By maintaining the existing beach profile, the high quality esthetics of the beach will be retained. (e) Parks, national and historic monuments, national seashores, wilderness areas, research sites, and similar preserves. Not applicable. g. Determination of Cumulative Effects on the Aquatic Ecosystem. The project should not contribute to any adverse cumulative impacts, as it is relatively isolated from other areas where beach construction activity has occurred or will occur. Biennial disrumt on of beach invertebrate macrofauna is not expected to have any significant long-term effects. *"No effect" determination changed to "may effect," March 7, 1986, based on possible impacts to nesting sea turtles. **No records of Section 401 completion exist. 6 G-6 y. h h. Determination of Secondary Effects on the Aquatic Ecosystem. secondary effects on the aquatic ecosystem are anticipated.

No significant adaptations of the guidelines were made relative to this evaluation. 2. All alternatives, except placement of fill material. proposed continued Federal feasible and environmentally alternative to the proposed on the aquatic ecosystem. flood proofing and no action, would require the Of all the alternatives considered, only the participation in the project is economically acceptable; therefore, there is no practicable discharges which would have less adverse effect 3. A Section 401 Water Quality Certificate has been requested from the State of North Carolina. Project construction will not violate the Toxic Effluent Standards of Section 307 of the Clean Water Act. 4. Continued maintenance of the existing project will not harm any endangered species or their critical habitat or violate the protective measures for any marine sanctuaries. 5. The proposed placement of fill material will not result in significant adverse effects on human health and welfare, including municipal and private water supplies, recreational and commercial fishing, plankton, fish, shellfish, wildlife, and special aquatic sites. The life stages of aquatic and other wildlife will not be adversely affected. Significant adverse effects on aquatic ecosystem diversity, productivity and stability, and recreational, esthetic, and economic values will not occur. 6. Appropriate steps to minimize potential adverse impacts of the discharge on aquatic systems include timing the nourishment actions to occur during periods of low biological activity and using short sand dikes on the beach to maximize retention of effluent. 7. On the basis of this analysis, the proposed fill si.te is specified as complying with the requirements of the guidelines. ROBERT K. HUGHES Colonel, Corps of Engineers District Engineer 8114-14 4 October 1982 G-8 DEPARTMENT OF THE ARMY Wilmington District, Corps of Engineers Post Office Box 1890 Wilmington, North Carolina 28402-1890 PUBLIC NOTICE AND NOTICE OF AVAILABILITY OF THE ENVIRONMENTAL ASSESSMENT (EA) AND FINDING OF NO SIGNIFICANT IMPACT (FONSI) WRIGHTSVILLE BEACH, NORTH CAROLINA, RENOORISHMENT PROJECT CESAW-PD-E-90-65-0009 TO WHOM IT MAY CONCERN: February 1, 1990 THE WILMINGTON DISTRICT, CORPS OF ENGINEERS, Wilmington, North Carolina, is preparing to renourish Wrightsville Beach, New Hanover County, North Carolina. PROJECT DESCRIPTION Renourishment of Wrightsville Beach is scheduled to be performed in the late spring and early summer 1990. Approximately 580,000 cubic yards of sandy material will be placed on the beach between stations 70+00 and 160+00 as shown on plates 1 and 2. The Masonboro Inlet and Banks Channel sediment trap/borrow areas will again be used for the 1990 renourishment. The borrow areas have been expanded to include an area approximately 1,250 feet long by 875 feet wide at the confluence of Banks Channel and the Masonboro Inlet Channel and an area approximately 600 feet long by 600 feet wide at the eastern end of the Masonboro Inlet Channel. The total borrow area is shown on plate 3. The material within the sediment trap/borrow areas consists of high quality beach sand which enters the system from Masonboro Inlet and is suitable for placement on the beach. The work will be accomplished by the use of a hydraulic pipeline dredge selected by competitive bidding. No related dredging and beach disposal conducted by others is anticipated. The discharge of fill material on Wrightsville Beach is covered under Water Quality Certification Nos. 1393, issued on April 30, 1980, and 1393-R, issued on September 30, 1980. The Section 404(b)(1) Evaluation and Findings of Compliance for the project were completed and signed on March 28, 1980, as amended on August 7, 1980, and October 4, 1982. The expansion of the borrow areas, shown on plate 3, does not alter the findings in the Section 404(b)(1) Evaluation Report and Finding of Compliance. The proposed action is discussed in the Environmental Assessment and Finding of No Significant Impact (A/FONSI) for the Continued Federal Participation in the Wrightsville Beach Shore and Hurricane Wave Protection Project, New Hanover County, North Carolina, which is included in the Feasibility Report dated September 1982, and in the Supplement to the EA/FONSI, signed on August 22, 1989, which is contained in the Wrightsville Beach, North Carolina, Renourishment Report dated September 1989. 1r A copy of the Supplement to the EA/FONSI which was signed on August 22, 1989, may be obtained by writing to Ms. Trudy Wilder, Environmental Resources Branch, Wilmington District, Post Office Box 1890, Wilmington, North Carolina 28402-1890. The proposed action is within the 100-year flood plain and has been evaluated for adherence to the requirements of Executive Order 11988. The action restores beaches and dunes and helps to minimize the impacts of floods on human safety, health, and welfare. The only other alternative is no action. In order to provide beach restoration for the authorized project, the fill material must be located in the flood plain. The proposed project conforms to applicable state and local flood plain protection standards. The proposed action has been evaluated under Executive Order 11990, Protection of Wetlands. The work will not require dredging or filling of any wetlands. The discharge pipeline may cross wetlands to reach the disposal site. Where the pipeline crosses wetlands, pipeline joints will be properly sealed to provide protection against leakage. Any impacts to wetlands will be minor and of short duration. No impacts to endangered species are expected if beach disposal occurs between November 16 and April 30. However, work to be performed between May 1 and November 15 could impact nesting loggerhead or green sea turtles, species protected by the Endangered Species Act of 1973, as amended. If dredged material is discharged on the beach during the turtle nesting season, daily monitoring of sea turtle nesting efforts in the beach impact area and nest relocation, as needed, will be performed in order to minimize potential adverse impacts to these species. Also, the hatching.success of all nests in the project area will be monitored. This work has been coordinated with the U.S. Fish and Wildlife Service and the N.C. Wildlife Resources Commission. Formal consultation with the U.S. Fish and Wildlife Service has been completed regarding the potential impacts of beach disposal on wintering piping plovers and transient roseate terns and to allow replacement of fill material on the beach during the sea turtle nesting season in 1990 and during future renourishment events, if it becomes necessary. The biological opinion received on December 21, 1989, states that the project will have no effect on piping plovers and roseate terns and is not likely to jeopardize the continued existence of the loggerhead and green sea turtles. No impacts to known archaeological/historical resources will occur. The proposed action is consistent with the approved Coastal Management Program of the State of North Carolina (N.C. Division of Coastal Management letter dated September 17, 1982). The Supplement to the EA/FONSI which was signed on August 22, 1989, amended our consistency determination of July 28, 1982, to include the expansion of the sediment trap/borrow areas. A request for concurrence/nonconetTrence with our amendment has been sent to the N.C. Division of Coastal Management (U.S. Army Corps of Engineers letter to State Clearinghouse, August 23, 1989). 2 Attached is a list of Federal, State, and local agencies with whom this activity is being coordinated. The decision whether to perform this work will be based on an evaluation of the probable impact, including cumulative impacts of the proposed activity on the public interest. That decision will reflect the national concern for both protection and utilization of important resources. The benefits which reasonably may be expected to accrue from the proposal must be balanced against its reasonably foreseeable detriments. All factors which may be relevant to the proposal will be considered, including the cumulative effects thereof; among those are conservation, economics, aesthetics, general values, flood hazards, flood plain values, land use, navigation, shoreline erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, considerations of property ownership, and in general, the needs and welfare of the people. Any person who has.an interest which may be affected by the disposal of this dredged material may request a public hearing. The request must be submitted in writing to the District Engineer within 30 days of the date of this notice and must clearly set forth the interest which may be affected and the manner in which the interest may be affected by this activity. In order for such a request to be given appropriate consideration, it should be mailed or delivered to the U.S. Army Engineer District, Wilmington, Post Office Box 1890, Wilmington, North Carolina 28402-1890, in time to be received on or before March 5, 1990. All correspondence should refer to the title, number, and date of this notice. For further information, contact Ms. Trudy Wilder at (919) 251-4581. Thomas C.

DEPARTMENT OF THE-ARMY Wilmington District,-Corps of Engineers Post Office Box 1890 Wilmington, North Carolina 28402-1890 PUBLIC NOTICE AMENDMENT .AND NOTICE OF AVAILABILITY OF THE AMENDMENT TO THE SUPPLEMENT TO THE ENVIRONMENTAL ASSESSMENT (EA) AND FINDING OF NO-SIGNIFICANT-IMPACT (FONSI) WRIGHTSVILLE BEACH.-NORTH CAROLINA, RENOURISHMENT PROJECT CESAW-PD-E-90-65-0012 March 15, 1990 TO WHOM IT MAY CONCERN: Renourishment of Wrightsville Beach, New Hanover County, North Carolina Public Notice CESAW-PD-E-90-65-0009 dated February 1, 1990, is amended as follows: PROJECT DESCRIPTION: Renourishment of Wrightsville Beach has been changed as follows: a. The work was scheduled to be performed in the late spring and early summer months of 1990. Work is now scheduled to begin in the summer of 1990 and will require approximately 90 days to complete. The Renourishment Plan is shown on the attached plates 1 and 2. b. The Masonboro Inlet sediment trap/borrow area has been expanded to include dredging an additional 1,800-foot-long by 600-foot-wide section of Masonboro Inlet, which is located seaward of sediment trap/borrow area A' (plate 3). The 1,800-foot-long by 600-foot-wide area in Masonboro Inlet will be dredged to remove several shoals lying above the plane of -20 feet mean-low-water (Navigational Survey, November 1989). The total quantity of material to be placed on Wrightsville Beach in 1990 remains 580,000 cubic yards. Performing the project in the summer of 1990 will require monitoring of the beach for sea turtles with possible nest relocation; therefore, a monitoring and nest relocation program has been established for the project and has been coordinated with the U.S. Fish and Wildlife Service and the N.C. Wildlife Resources Commission. The Supplement to the Environmental Assessment and Finding of No Significant Impact (EA/FONSI) dated August 22, 1989, has been amended to include dredging the 1,800-foot-long by 600-foot-wide area in Masonboro Inlet. The Supplement AL to the EA/FONSI and the amendment-are available to the public and may be obtained by writing Ms. Trudy Wilder, Environmental Resources Branch, Wilmington District, Corps of Engineers, Post Office Box 1890, Wilmington, North Carolina 28402-1890. The changes described herein are consistent with the approved Coastal Management Program of the State of North Carolina. Inclusion of dredged material from Masonboro Inlet in the discharge on Wrightsville Beach for beach renourishment does not alter the findings in the Section 404(b)(1) (P.L. 95-217) Evaluation Report and Findings of Compliance prepared for the Continued Federal Participation in the Wrightsville Beach Shore and Hurricane Wave Protection Project, New Hanover County, North Carolina, signed on October 4, 1982. A request to amend Section 401 Water Quality Certificate Nos. 1393, issued on April 30, 1980, and 1393-R, issued on September 30, 1980, to include the Continued Federal Participation in the Wrightsville Beach Shore and Hurricane Wave Protection Project, New Hanover County, North Carolina, and the discharge of material from the expanded sediment trap/borrow sites in Banks Channel and Masonboro Inlet has been sent to the North Carolina Division of Environmental Management. The changes described herein will not impact known archaeological/historical resources located within Masonboro Inlet, endangered species, or their critical habitat. Attached is a list of Federal, State, and local agencies with whom this activity is being coordinated. The decision whether to perform this work will be based on an evaluation of the probable impact, including cumulative impacts of the proposed activity on the public interest. That decision will reflect the national concern for both protection and utilization of important resources. The benefits which reasonably may be expected to accrue from the proposal must be balanced against its reasonably foreseeable detriments. All factors which may be relevant to the proposal will be considered, including the cumulative effects thereof; among those are conservation, economics, aesthetics, general values, flood hazards, flood plain values, land use, navigation, shoreline erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, considerations of property ownership, and in general, the needs and welfare of the people. Any person who has an interest which may be affected by the disposal of this dredged material may request a public hearing. The request must be submitted in writing to the District Engineer within 15 days of the date of this notice and must clearly set forth the interest which may be affected and the manner in which the interest may be affected by this activity. 2 In order to be given appropriate consideration, all comments should be mailed or delivered to the U.S. Army Engineer District, Wilmington, Post Office Box 1890, Wilmington, North Carolina 28402-1890, in time to be received on or before March 30, 1990.

The project covers 14,000 feet of ocean shoreline extending north from Masonboro Inlet and consists of a beachfill shaped in the form of a 25-foot-wide dune at elevation 15 feet above mean low water datum (MLW) fronted by a 50-foot-wide storm berm at elevation 12 feet MLW. The equivalent elevations of the dune and storm berm referenced to the National Geodetic Vertical Datum (NGVD) are 13.5 feet and 10.5 feet NGVD, respectively. The National Geodetic Vertical Datum will be used throughout the remainder of this report. The project limits and design cross section are shown on Figures 1 and 2, respectively. The project was initially constructed in 1965; however, slope adjustments and sorting losses from this initial fill during the first 2 years of project operation resulted in a substantial reduction in the degree of protection provided by the fill. This design deficiency was corrected in 1970 with the restoration of the design cross section and placement of sufficient quantities of material to account for fill adjustments. Following the 1970 restoration, the project was declared officially completed and was turned over to the Town of Wrightsville Beach. Federal cost sharing for beach renourishment was authorized for a period of 10 years following the completion of the initial construction. At the end of this 10-year period, Federal interest was to be reevaluated to determine if Federal cost sharing for beach renourishment should continue. A reevaluation of the Wrightsville Beach project was made in September 1982 with the results provided in a report entitled "Feasibility Report and Environmental Assessment on Shore and Hurricane Wave Protection, Wrightsville Beach, North Carolina." As a result of this reevaluation, the Wrightsville Beach project was reauthorized by the Water Resources a. aAp- =!GURE W a 1. 4 w O a a E- U W ti O A~ a W W W V W _Z J Z ti J ti O C r L 0 z 0 H U W H O a /W w O V• Q W N M?

Also included in this new authorization was a provision for periodic beach nourishment for Figure 8 Island, North Carolina, which lies just to the north of Wrightsville Beach. Figure 8 Island is an exclusive private island development that is not open to the general public. Therefore, any fill placed on Figure 8 Island would have to be accomplished without Federal financial assistance. At the present time, there is no planned nourishment of Figure 8 Island that involves the active participation of the Federal Government. PROJECT HISTORY The initial construction of the Wrightsville Beach project, which was accomplished in 1965, involved the placement of 2,993,000 cubic yards of material along the 14,000 lineal feet of project shoreline. Included in the initial construction was the closure of a small tidal inlet known as Moore Inlet which was located in the north boundary of the town. Upon completion of the initial fill, construction of the north jetty at Masonboro Inlet was begun. The north jetty, which was completed in July 1966, has a weir section nearshore which allows the predominant southbound littoral drift to pass over and deposit in a deposition basin inside the inlet. The deposited material is periodically removed and placed on both Wrightsville Beach and Masonboro Island to mitigate jetty induced erosion. The south jetty at Masonboro Inlet was completed in 1980. The material to initially construct the Wrightsville Beach project was obtained from Banks Channel, a narrow sound lying immediately behind Wrightsville Beach (see Figure 1). The material was not entirely suited for beachfill; consequently, the fill experienced some initial high rates of erosion due to sorting and winnowing of the fines. In addition, slope 2 adjustments occurred that resulted in large quantities of the fill material being moved downslope to deeper portions of the active beach profile. The erosion of the upper portion of the fill profile that occurred with this offshore movement was primarily due to the failure to place a sufficient quantity of sand to nourish the entire active profile. At Wrightsville Beach, the active profile extends to a depth of about 20 to 25 feet below NGVD whereas the design slopes assumed for the fill closed in depths of between 6 and 10 feet NGVD. An example of these initial fill adjustments is given on Figure 3. Between March and July 1966, Wrightsville Beach received an additional 319,000 cubic yards of fill as a result of the construction of a deposition basin adjacent to the Masonboro Inlet north jetty. No additional fill was placed on Wrightsville Beach until 1970 at which time 1,377,000 cubic yards was placed along the northern 8,000 feet of the project to correct the earlier design deficiency and replace material lost due to sorting and winnowing. The material for this operation was obtained from the southern end of Banks Channel near Masonboro Inlet and from the sound behind Shell Island. The southern 6,000 feet of the project was and continues to be stable as it is situated within the accretion fillet of the Masonboro Inlet north jetty. In April 1980, approximately 541,000 cubic yards of sand obtained from the southern end of Banks Channel was placed along the northern 8,000 feet of the project to replace sand lost as a result of Hurricane David, which passed near the area in September 1979. However, this sand did not completely restore the design cross section. The northern section of Wrightsville Beach was completely restored between December 1980 and April 1981 with the placement of 1,250,000 cubic yards of sand obtained from Masonboro Inlet. The latest nourishment occurred between April and June 1986 when about 900,000 cubic yards of sand removed from Masonboro Inlet in connection with sand bypassing was placed along the northern portion of the project. The nourishment history of the Wrightsville Beach project is given in Table 1. 3 1 1 I tD 1 ow 1 Cf J 1 ^ U- -JO 1 cr- C. 1 < r, i ; 1 1 1 1 ?• 1 , I i 1 1 I ? - 1 1 to 1 ? : t0 1 / / cr- 4f I / : W a.

The southern 6,000 feet, which lies within the accretion fillet formed by the Masonboro Inlet north jetty, is stable and does not require nourishment. The 1970 fill underwent an initial period of adjustment which lasted from August 1970 (completion date of the fill) to February 1972. During this period, approximately 438,000 cubic yards of the fill was lost as a result of sorting and winnowing. Following these initial losses, the shoreline behavior became more uniform although erosion losses were still greater than those which had been predicted by the pre-project shoreline history. For example, the volumetric rate of loss from the entire project during the August 1970 to December 1979 period, excluding sorting and winnowing losses, was determined to be 130,000 cubic yards/year whereas the pre-project losses were estimated to be 29,000 cubic yards/year. 4 The disparity between the erosion rate predicted by the pre-project shoreline behavior and the rates actually experienced can be partially explained by the change in the physical boundary conditions of Wrightsville Beach following project construction. The major changes were the closure of Moore Inlet and the stabilization of Masonboro Inlet. In addition, some of the earlier problems with slope adjustments were corrected through the placement of proper fill quantities. A brief discussion of these performance factors follows. Design fill volumes. The volume of fill required to initially construct the Wrightsville Beach project was based on design fill slopes that were relatively steep compared to existing profile slopes. This resulted in the design profile intersecting the existing beach profile in relatively shallow depths, as shown on Figure 3. Quarterly monitoring surveys of the fill showed that wave action was reshaping the fill with the newly formed slopes tending toward parallelism with the pre-project slopes. These slope adjustments are also shown on Figure 3. With this movement of material offshore, the upper or visible portion of the project appeared to be eroding at a rapid rate. In order to avoid a reoccurrence of this situation, design fill volumes are now computed on the basis of moving the entire active profile seaward by the required amount. This concept is shown on Figure 4. Since construction procedures do not permit controlled placement of material in the deeper depths, the fill material is placed in a construction berm, as shown on Figure 4, with the distribution to the deeper depths accomplished by wave action. The width of the construction berm depends on the fill quantity required and the slope the material assumes during placement. Changes in physical boundary conditions. The two actions that had the greatest impact on the performance of the Wrightsville Beach project were the closure of Moore Inlet and the construction of the north jetty at Masonboro Inlet: These two man-made changes affected the project in the following ways. 5 i + o ?- I ti I O 1 V 1 / = 1 o I / I J 1 / .J..

U z W q z N W CL a c 'W a u_ W V N o a a h-1 w z CS 1--1 q W w Barrier islands in North Carolina have a characteristic concave seaward shape between the bordering inlets. This concavity is the result of the interruption of littoral sediment transport caused by tidal currents flowing in and out of the inlets. These tidal currents trap sediment in an offshore bar and the bar in turn causes waves to refract in such a manner so as to drive sediment toward the inlet from both sides. Thus, with sediment moving toward the bordering inlets most of the time, the middle of the islands retreat and align themselves essentially parallel to the predominant direction of incoming waves. Prior to the closure of Moore Inlet, Shell Island had a concave shape between Masons Inlet on the north and Moore Inlet on the south while Wrightsville Beach was concave between Moore and Masonboro Inlets. The artificial closure of Moore Inlet connected the shoreline of Shell Island with Wrightsville Beach, thus creating a convex shoreline configuration between Masons Inlet and Masonboro Inlet. This convexity is illustrated on Figure 5. The anomalous shape of Wrightsville Beach results in wave energy being concentrated along the bulge and wave breaker angles on the bulge transition that vary from normal breaker angles. These conditions upset the normal rates of sediment transport and cause increases in sediment transport away from the bulge in both the north and south directions. Without continued nourishment, the natural tendency would be for Wrightsville Beach to assume a convex shape between Masons and Masonboro Inlets with the resulting shoreline near the center of the island eventually moving several blocks inland. Of the total 130,000 cubic yards/year deficit estimated for the Wrightsville Beach project, 41,000 cubic yards/year was attributed to the effects of the bulge. The analytical method used to ascribe the sediment losses -to the shoreline bulge is presented in detail in the Wrightsville Beach Feasibility Report cited previously. The impact of the Masonboro Inlet stabilization project on Wrightsville Beach was determined through deductive reasoning. Prior to the construction of the north jetty, natural sediment bypassing apparently occurred at rather 6 f ON Q V Q w m W Al Zt i p t r. En Lli LL high rates across Masonboro Inlet. For example, the average sediment transport rates for Wrightsville Beach are 770,000 cubic yards/year to the south and 330,000 cubic yards/year to the north. Even with these rather large quantities of sediment transport, the pre-project deficit on Wrightsville Beach was only 29,000 cubic yards/year. This long term deficit was due to losses associated with the gradual rise in sea level, offshore losses during severe storms, and retention in the bordering inlets. Adding this historic deficit to that created by the anomalous shoreline configura- tions accounts for 70,000 cubic yards/year leaving 60,000 cubic yards/year, or 46 percent, to be assigned to some other cause(s). Since no other factor could be identified, the remaining 60,000 cubic yard/year deficit was assigned to the Masonboro Inlet stabilization project as that project completely eliminated natural sand bypassing. Due to the variability in erosion losses during any given time period, the contribution to the erosion losses attributable to the causative factors has been expressed in terms of percentages of the total erosion. Accordingly, the Masonboro Inlet navigation project is responsible for 46 percent of the erosion on Wrightsville Beach with the remaining 54 percent assigned to the historical deficit and that created by the bulge. Beachfill behavior since last renourishment. The latest renourishment of Wrightsville Beach was completed in July 1986 in conjunction with the sand bypassing operation in Masonboro Inlet. A total of approximately 900,000 cubic yards of sand was removed from the sediment trap/borrow areas in Masonboro Inlet, with the exception of the expansion areas, which are shown on Plate 3, and placed along the project shoreline north of Station 70+00. Approximately 1.1 million cubic yards of sand was placed on Masonboro Island during this same operation. With the expiration of Federal participation in beach nourishment for Wrightsville Beach in FY 1980, the cost of placing additional material on Wrightsville Beach over and above that needed to mitigate the effects of the jetties was paid by non-Federal interests. Thus, approximately 415,000 cubic yards was placed at Federal expense to offset the erosive effects of the Masonboro Inlet jetties that had occurred during the 6 years (1980-1986) since the completion of the 7 completion of the south jetty and 485,000 cubic yards placed at local expense to make up fD r the other deficits. The 900,000 cubic yards dredged in 1986 was measured in the borrow area whereas beach profile surveys taken before and after the fill accounted for 763,400 cubic yards. The 18-percent difference between the borrow area measure and the inplace fill measure could represent losses during placement or simply measurement inaccuracies. In any event, the difference between the two measures was small, reflecting the good quality of the borrow material removed from the inlet. The good quality of the fill material was expected as most of the material removed was beach sand that had deposited in previously dredged sediment traps/borrow areas. The time history of the amount of the 1986 fill remaining on the beach is shown on Figure 6. As has been the case for all past nourishments, the initial losses from the fill were relatively large but eventually moderated after about one year. Some of the initial losses occur downslope as evidenced by the more rapid rate of loss of material above 0 NGVD during the first year versus the rate of loss below 0 NGVD as shown on Figure 6. Other losses occur upcoast (north) and downcoast (south) outside the nourishment limits. The fill volume remaining, as depicted on Figure 6, only covers the section of the beach nourished in 1986, i.e., between Stations 70+00 and 160+00. Note that the nourished area includes a 1,000-foot southern transition and a 2,000-foot northern transition. The material that moves alongshore outside these nourishment limits provides some benefit to the adjacent areas. In this instance, since the southern area is stable as a result of the fillet created by the Masonboro Inlet north jetty, the major benefactor has been the Shell Island shoreline. The Shell Island shoreline has been stable to slightly accretionary since 1965 when nourishment of Wrightsville Beach was initiated. The Wrightsville Beach area was affected by two rather severe northeast storms shortly after the completion of the 1986 nourishment operation.

These two storms produced surges of 2 to 3 feet and occurred when the predicted astronomical tides were at their maximum for the year. The so-called syzygy storms (due to the alignment of the earth, moon, and sun) caused considerable structural damage along the southern end of Topsail Beach, located north of Wrightsville Beach, and the west end of Long Beach located in Brunswick county south of Wrightsville Beach. The only impact that these two storms had on Wrightsville Beach was the hastening of the slope adjustment of the fill as there were no apparent lasting or detrimental effects. Wrightsville Beach was also affected by a severe northeast storm during the period 6 to 10 March 1989. The storm, which occurred during a period of spring tides, produced water levels about 2 feet above normal. The high water levels combined with the long duration of the storm caused significant erosion all along the North Carolina coast north of Cape Fear. Particularly hard hit was the area north of Oregon Inlet. The amount of erosion at Wrightsville Beach caused by this storm could not be determined directly since the prestorm survey was taken in October 1988. A poststorm survey was made on 13 March 1989 which covered the area from the landward toe of the dune seaward to the mean high water line. A comparison between the October 1988 and 13 March 1989 surveys indicated between 10 and 30 feet of dune erosion with an average retreat of about 23 feet. Allowing for normal recession that should have occurred between October 1988 and March 1989, the March "northeaster" appears to have caused about 15 to 20 feet of dune retreat. The volume of material eroded from the upper profile was 70,000 cubic yards between October 1988 and March 1989. Some of this material was deposited offshore beyond the survey limits and will likely return to the foreshore during the spring and summer months. 9 N i I 1 O uj O IA O IA I 1 C NDN) 133 NI NOI1VA313 0 0 0 0 0 vl 0 0 0 U- W Z O ui N m N O cr.

At the present time, the fill along the major portion of Wrightsville Beach is still in fair condition. The most critical area, in terms of reduced storm protection lies between baseline Station 90+00 and 110+00 with some reduction in protection below the authorized level existing north of Station 110+00. Typical profiles showing the existing condition of the Wrightsville Beach project are given on Figures 7 and 8. The beach south of Station 70+00 does not need any material as the existing beach profile equals or exceeds the authorized design cross-section. Renourishment of Wrightsville Beach should begin early in calendar year 1990, preferably no later than February 1, 1990, in order to avoid the sea turtle nesting season which runs from May 1 to November 15. The projected losses from the 1986 fill by February 1, 1990, are 580,000 cubic yards as shown on Figure 6. The projected losses should cover the erosion caused by the March 1989 "northeaster." Since the 1986 fill performed well, the fill dimensions achieved in 1986 should be duplicated in 1990. Thus, the 1990 fill require- ments are projected to be 580,000 cubic yards inplace on the beach. The 580,000 cubic yard loss projected for the 1986 fill by February 1990 represents an approximate average erosion rate of 145,000 cubic yards/year. This rate agrees well with the 130,000 cubic yard/year erosion rate that has been used in long-term planning for the Wrightsville Beach project. The plan layout for the 1990 renourishment and typical cross-section of the fill are shown on Plates 1 and 2. The projected fill requirements between each baseline station, expressed in terms of both the inplace fill volume and borrow area measure, is given in Table 2. The borrow area measure was assumed to be 20 percent greater than the inplace fill require- ment based on actual experience with the 1981 and 1986 renourishments. 10 Table 2 Estimated 1990 Nourishment Requirement for Wrightsville Beach Baseline In Place Fill Quantity Borrow Area Measure Station Incremental Cumulative Incremental Cumulative Volume Volume Volume Volume Cy Cy Cy CY 70+00 17,400 17,400 20,880 20,880 80+00 72,500 89,900 87,000 107,880 90+00 104,400 194,300 125,280 233,160 100+00 87,000 281,300 104,400 337,560 110+00 81,200 362$00 97,440 435,000 120+00 87,000 449$00 104,400 539,400 130+00 75,400 524,900 90,480 629,880 140+00 43$00 568,400 52,200 682,080 150+00 11,600 580,000 13,920 696,000 160+00 Borrow areas. The Masonboro Inlet and Banks Channel se diment trap/ borrow areas used in the 1986 sand bypassing and renourishment operations, as shown on Plate 3, will again be used for the 1990 renouri shment. The borrow areas have been ex panded to include an area approximately 1,250 feet long by 875 feet wide a t the confluence of Banks Channel and t he Masonboro Inlet Channel and an area approximately 600 feet long by 600 f eet wide at the eastern end of the Masonboro Inlet Channel. The total bo rrow area is shown on Plat e 3. A supp lement to the Environmental Assessment and Finding 11 of No Significant Impact has been prepared for the expansion of the existing sediment traps/borrow areas and is included in this report following Appendix A. A scour and fill diagram of the sediment trap/borrow area which covers the period from after dredging in 1986 to September 1988 (a period of about 2 years) is shown on Plate 4. The overall performance of the sediment trap during this 2-year period was excellent as the trap had a net accumulation of 562,000 cubic yards. This represents an average accumulation of 281,000 cubic yards/year which agrees well with the predicted accumulation of 298,000 cubic yards/year estimated in the September 1982 feasibility report. There were two main areas of sediment accumulation between the jetties and one major scour area. The scour area was due to the navigation channel which has been self-maintaining since construction of the south jetty in 1986. The two fill areas are located on either side of the channel with the north area having the largest accumulation. This northern area, designated as Borrow Area A on Plate 3, trapped a total of 421,000 cubic yards of sand during the 2-year period. The fill area on the south side, designated as Borrow Area A', trapped 89,100 cubic yards. The amount of scour between the jetties, which was caused primarily by the navigation channel, totaled 156,200 cubic yards, yielding a net accumulation between the jetties of 354,000 cubic yards. The Banks Channel sediment trap, designated as Borrow Area B on Plate 3, trapped a net volume of 208,000 cubic yards. Of this net accumulation, 263,000 cubic yards was fill and 55,000 cubic yards was scour. Over half of the net accumulation occurred within 1,500 feet of the confluence of Banks Channel and Masonboro Inlet. All of the material deposited in the inlet during the 2-year period is high quality beach sand, having entered the inlet primarily from Wrightsville Beach by crossing over the north jetty weir or passing through the large voids in the rubblemound portion of the north jetty. Very little, 12 if any, littoral material is able to enter Masonboro Inlet from the south due to the concrete sheetpile core of the south jetty. Some material may enter the inlet from Masonboro Island through aeolian process or possibly around the seaward end of the structure. These two contributions are believed to be relatively small. The sediment traps in Masonboro Inlet and Banks Channel still have the capacity to trap additional sand and will continue to do so up until the time nourishment begins. With a continuation of the entrapment rate experienced during the first 2 years, the projected net accumulation of new sand between the jetties and in Banks Channel will be between 950,000 and 1,000,000 cubic yards. The new sand that has accumulated and will accumulate in the trap areas does not represent all of the material available from these borrow areas. The borrow areas located between the jetties have environmental clearances to be dredged to 20 feet below mean low water (MLW) whereas the Banks Channel area is authorized to 30 feet below MLW. If these depths are attained, approximately 638,000 cubic yards of sand would be available from Borrow Area A and over 1,100,000 cubic yards available from Borrow Area B. At the present time there are no plans to use Borrow Area A' due to the narrow distribution of sediment which would require frequent movement of the dredge and thus render this area more expensive to use compared to Areas A and B. In both the inlet and Banks Channel, previous dredging operations associated with the Wrightsville Beach project and the Masonboro Inlet navigation project have at one time or another deepened both areas to their environmentally cleared limits. Therefore, the majority of the material removed from the borrow areas down to these depths will be sand derived from the adjacent beaches, and in this case, primarily Wrightsville Beach. Thus, the compatibility ratio for the borrow material will be 1:1, i.e., the borrow material is completely suitable for placement on the beach. 13 The 20-percent difference between the volume of material to be removed from the borrow areas and that measured inplace on the beach, as given in Table 2, does not represent an overfill factor to account for material incompatibilities. Rather it is a measurement factor to assure that the needed quantity of material is removed from the borrow area. If payment were based on inplace measurement, the 20-percent factor would not be required; however, past experience has shown that when inplace measurement is used as a basis for contractor payment, the contractor will normally inflate his bid by more than 20 percent to account for the uncontrolled losses from the fill. Thus inplace measure usually costs more than payments based on borrow area measure. Accordingly, the best method of constructing the fill is to base contractor payment on measurements in the borrow area and control the amount of material placed on the beach with before and after beach profiles. Real Estate Requirements. All of the necessary lands, easements, and rights-of-way for the Wrightsville Beach project were in place prior to the 1965 initial construction phase. A town building line, located along the ocean shoreline, was established in 1939. All land seaward of this building line is owned by the Town of Wrightsville Beach. In 1967, the building line was extended northward to include Shell Island, which had become attached to Wrightsville Beach when Moore Inlet was closed. During past nourishment operations, the dredge discharge pipeline has been laid along the beach seaward of the town building line or floated in Banks Channel to existing cross-island pipeline easements located at Bridger Street (near Corps of Engineers baseline station 50+00), Chadbourn Street (near baseline station 80+00), and Mallard Street (near baseline station 130+00). These existing pipeline easements are adequate for this and future nourishment operations. The borrow areas for the Wrightsville Beach project are located in State owned submerged lands inside Masonboro Inlet and Banks Channel. The use of 14 these areas has previously been approved except for the expansion areas discussed below; however, all the State and Federal environmental agencies are notified prior to each nourishment operation. No real estate costs are associated with the use of these borrow areas. There will be no additional real estate requirements for Wrightsville Beach associated with this or future nourishment operations as all of these requirements have been satisfied as a result of previous renourishment efforts. Environmental resources considerations. A Feasibility Report and Environmental Assessment and Finding of No Significant Impact (EA/FONSI) for the Wrightsville Beach Shore and Hurricane Wave Protection Project, New Hanover County, North Carolina, was prepared in September 1982. The Feasibility Report and EA/FONSI covered all aspects of the project, including the use of Masonboro Inlet and Banks Channel as sources of borrow material. The impacts of expanding the sediment trap/borrow areas to those shown on Plate 3 are discussed in the Supplement to the EA/FONSI attached to this report. The expansion of the Masonboro Inlet borrow area will include an area at the most western end which will be dredged to a depth no greater than -20 feet MLW. Dredging throughout the Masonboro Inlet borrow area, including the expansion area, is confined to 20 feet MLW to avoid impacts to known archeological/historic resources. The expansion of the Banks Channel borrow area will be dredged to a depth of -30 feet MLW. The expansion of the borrow areas has been reviewed for archeological/historic concerns. The magnetic surveys conducted in the late 1970's indicate that no effect to known cultural resources will occur as long as the Masonboro Inlet borrow areas are not dredged below -20 feet MLW. The expansion of the borrow areas is consistent with the approved Coastal Management Program of the State of North Carolina (N.C. Department of Natural Resources and Community Development, Division of Coastal Management letter, dated September 17, 1982). The Supplement to the 15 EA/FONSI amends the existing consistency determination to include the expanded borrow areas. Placement of the material on Wrightsville Beach is covered under Section 401 (P.L. 95-217) Water Quality Certifications number 1393 issued April 30, 1980, and number 1393-R issued September 30, 1980. A Section 404(b)(1) Evaluation Report and Finding of Compliance for the Wrightsville Beach Renourishment project was signed on October 4, 1982. The expansion of the borrow areas does not alter the findings in the Section 404(b)(1) Evaluation Report and Finding of Compliance and it will, therefore, not require revision. A public notice will be mailed to interested and concerned agencies for information prior to onset of work. Cost estimate for FY 90 renourishment. A summary of the estimated cost of placing 580,000 cubic yards of sand on Wrightsville Beach is given in Table 3. The material quantity given in the Detailed Cost Summary in Table 3, which is 696,000 cubic yards, is the estimated amount of material that would have to be removed from the borrow areas in Masonboro Inlet and Banks Channel in order to yield the required quantity of inplace sand. The 696,000 cubic yards of material would be obtained from Borrow Area A and possibly a portion of Borrow Area B near the confluence of the inlet and Banks Channel. The exact areas to be used for the 1990 renourishment will depend on the distribution of additional littoral material that will enter the inlet complex by the time the renourishment operation begins. First cost and annual cost of the Wrightsville Beach project. Only 54 percent of the total cost of the FY 90 renourishment operation given in Table 3 i.s associated with the Wrightsville Beach Shore and Hurricane Wave Protection project with the remaining 46 percent allocated to sand bypass- ing for the Masonboro Inlet navigation project. Thus, the first cost of restoring the Wrightsville Beach project is $1,047,600. 16 Table 3 PROJECT COST SUMMARY COST ESTIMATE FY 90 RENOURISHMENT PROJECT WRIGHTSVILLE BEACH, NORTH CAROLINA FEBRUARY 1, 1989 PRICE LEVEL 12.-.-.- DREDGING TOTAL DREDGING COST 30.-.-.- PLANNING, ENGINEERING AND DESIGN 31.-.-.- CONSTRUCTION MANAGEMENT TOTAL PROJECT COSTS 17 Estimated Total Cost Contingency Cost -----------------------------.------ $1,526,000 $229,000 $1,755,000 ----------------------------------- $1,526,000 $229,000 $1,755,000 87,000 13,000 100,000 74,000 11,000 85,000 ----------------------------------- $1,687,000 $253,000 $1,940,000 WRRCiHRRN - WV I -Trr t i - n...[-nn Table 3 (Continued) Detailed Cost Summary TOTAL 1000UIT BIT PROJECT CODE ITEM QUWITY UNIT PRICE AMOUNT COITI1=CY COST ------------------------------------------------------------------------------------------------------- 12.-.-.- DREDGIIG 12.0.1.- Mobilization and Demobilization 1 JOB LS $350,000 $53,000 $403,000 12.0.2.B Pipeline Dredging 696,000 CY $1.69 1,176,000 176,000 1,352,000 ------------------------------------ Subtotal, Dredging Costs: $1,526,000 12.0.Z.- Contingencies 12.-.-.- Dredging Total: 18 $229,000 11,755,000 MWOUDru WI-TCn Renourishment of Wrightsville Beach is scheduled to be accomplished at 4-year intervals with each operation coinciding with sand bypassing at Masonboro Inlet. The cost of future operations was assumed to be the same as the FY 90 renourishment, i.e., a total nourishment cost of $1,940,000 with $1,047,600 assigned to the Wrightsville Beach project. The amount of material to be placed during the FY 90 renourishment is equivalent to an average annual amount of 145,000 cu yds/year. This annual rate of nourishment is slightly greater than the 130,000 cu yd/year rate used in previous estimates. In addition to the renourishment cost, local interest will be required to continue to maintain the vegetative cover of the dune. This will require fertilization and possibly some replanting to replace diseased or damaged dune grasses. A summary of the project first cost, including interest during construction, and average annual cost is provided in Table 4 for interest rates of 8-5/8, 8-7/8, and 10 percent.

The Economic impact of continued renourishment of Wrightsville Beach for the life of the project was based on the same general analysis contained in the 1982 Feasibility Report, but with certain date changes to reflect developments that have taken place since the completion of the Feasibility Report. The "without" project condition in the 1982 report assumed no additional nourishment would occur following the 1981 restoration except for that associated with sand bypassing at Masonboro Inlet. Based on this assumption and an average erosion rate of 8.9 ft/year, the shoreline north of baseline station 50+00 would erode to the pre-project position by 2005 and the first structures would be lost to erosion by 2010. The shoreline south of station 50+00 would not erode as it lies within the stable accretion fillet of the Masonboro Inlet north jetty. With the reconstruction of the Wrightsville Beach project in 1986, the assumed time table in the 1982 report for the "without" project condition had to be shifted 5 years using 1986 rather than 1981 as the base year after which no beach nourishment would occur. Thus, erosion would now reach the pre-project shoreline position in 2010 and the first structures would be lost to erosion in 2015 if nourishment is not continued. The 1982 report also assumed that for the "with" project condition, the first restoration would occur in 1987 whereas the first renourishment is presently scheduled for 1990. Thus, the recomputation of project benefits used 1990 as the initial project year and extended over a 50-year period. The 50-year economic period was chosen in order to be consistent with other civil works projects even though the Water Resources Development Act of 1986 authorized renourishment for the "life" of the project. "Life" in this case means as long as non-Federal interest continue to conform to the terms of local cooperation. 20 Erosion control benefits. If the Wrightsville Beach project is not periodically nourished, progressive erosion will encroach onto pre-project lands by 2010 and begin causing damage to structures by 2015. The average annual value of land loss that would occur between 2010 and 2040 for interest rates of 8-5/8, 8-7/8, and 10 percent would be $179,700, $172,400, and $142,700, respectively. In the 1982 report, the land loss benefits were based on actual land values including the higher priced oceanfront lots. In this reanalysis, the value of all future land losses without the project was based on the average land value of second and third row lots. The value of structures lost to progressive erosion for the year of the assumed loss is given in Table 5. Table 5 Structure Damage due to Progressive Erosion Year of Loss Value of Structures Lost 2015 $1,800,400 2021 9,871,000 2027 22,134,000 2032 1,464,300 2035 2,021,200 The average annual value of the structure losses for interest rates of 8-5/8, 8-7/8, and 10 percent would be $185,600, 176,400, and 139,800, respectively. All of the land losses and structure losses that would occur due to the progressive erosion are preventable by continuing to periodically nourish Wrightsville Beach. Flood damage reduction benefits. Wrightsville Beach is essentially fully developed with very few empty lots remaining on the island. Therefore, when progressive erosion threatens existing structures, they would be abandoned and eventually torn down as there is no practical place to relocate. As a result of the structure losses that would be caused by progressive erosion for the "without" project condition, preventable flood 21 damages in future years would decrease over time. The declining structure base for the "without" project condition was taken into account in computing the storm damage reduction benefits. Storm damage reduction benefits for the three interest rates are given in Table 6. Table 6 Summary of Average Annual Benefits for Continual Nourishment of Wrightsville Beach Benefit Category Average Annual Benefits for Interest Rates of 8-5/8% 8-7/8% 10% Erosion Control: (a) Lands $179,700 $172,400 $142,700 (b) Structures 185,600 176,400 139,800 Flood Damage Reduction to Structures 185,300 183,800 177,400 Increase in Value of Residential Contents 19,500 19,300 18,300 Total Storm Damage Reduction Benefits $570,100 $551,900 $478,200 Recreation 386,300 372,900 317,700 Total Average Annual Benefits $956,400 $924,800 $795,900 Recreation benefits. Wrightsville Beach is open to the general public on an equal basis. Public beach access points are provided all along the beach at 250- to 500-foot intervals. The public beach access points are essentially located at street ends with a walkway provided from the end of the street across the dune to the beach strand. Parking on Wrightsville Beach is limited with most parking spaces located along side streets. Public parking lots are situated near the two fishing piers and at each end of the island. 22 The recreation benefits presented in the 1982 Feasibility Report were updated for new unit day values while the remainder of the analysis was not changed. That is, the availability of parking spaces continues to limit beach use. The updated recreational benefits for the three interest rates are also given in Table 6. The recreational benefits for Wrightsville Beach, which account for about 40 percent of the total benefits, are incidental to the primary purpose of the project which is to reduce storm damages. That is, no special features were added to the project to accommodate recreation activities. Benefit-cost summary. A summary of the benefits and costs for the continued nourishment of the Wrightsville Beach project for the three interest rates is given in Table 7. Table 7 Benefit-Cost.Summary - Continued Maintenance of the Wrightsville Beach Project 50-Year Period of Analysis 8-5 /8 % 8-7 /8 % 10% Total Average Annual Benefits $956,400 $924,800 $795,900 Total Average Annual Costs 327,100 328,800 335,700 Benefit to Cost Ratio 2.9 2.8 2.4 Cost allocation. The Water Resources Development Act of 1986 (PL 99-662) changed the cost sharing on coastal protection projects by eliminating a distinction between coastal erosion protection and storm damage reduction. Prior to the enactment of PL 99-662, project purposes were apportioned between erosion control and storm protection with the erosion control portion cost shared 50 percent Federal - 50 percent non-Federal while storm damage reduction features were split 75 percent Federal - 25 percent non-Federal. Under the new cost sharing rules established by PL 99-662, the Wrightsville Beach project is classified as a 23 storm damage reduction project since over 50 percent of the project benefits are for storm protection. In the case of Wrightsville Beach, 60 percent of the project benefits are for storm damage reduction while only 40 percent are for recreation enhancement. Furthermore, the recreational benefits are incidental to the project since no special features were added to accommodate beach users. Thus, since Wrightsville Beach is open to the general public and the primary purpose of the project is to reduce storm damages with only incidental recreational benefits, the Wrightsville Beach project qualifies for 65 percent Federal and 35 percent non-Federal cost sharing as established by PL 99-662. Funding requirements. The total cost for completed restoration of the Wrightsville Beach project in 1990, including both Operation and Maintenance funds for sand bypassing at Masonboro Inlet and Construction General funds for project nourishment is $1,940,000. Forty-six percent of this total cost, or $892,400, is allocated to the Masonboro Inlet project for sand by- passing. Sand bypassing is a 100% Federal responsibility. The remaining $1,047,600 of the nourishment cost is allocated to the Wrightsville Beach project for which the Federal share would be $680,900 (65%) and the non-Federal share $366,700 (35%). 24 RECOMMENDATIONS I recommend that the Wrightsville Beach Shore and Hurricane Wave Protection project should be fully restored to its authorized project dimensions in accordance with the plans presented in this report. The full restoration should be accomplished using a combination of Federal Operation and Maintenance (0&M) funds for sand bypassing at Masonboro Inlet, Federal Construction General funds, and non-Federal cash contributions. The estimated Federal 0&M requirement for bypassing sand from Masonboro Inlet to Wrightsville Beach is $892,400 while Federal Construction General funding requirements amount to $680,900. The required non-Federal cash contribution is presently estimated at $366,700. 7-1'a( THOMAS C. SUERMANN LTC, Corps of Engineers Commanding 25 D "MM t, IE D' F- s LEGEND U. S. ARMY ENGINEER DISTRICT.

IN WITNESS WHEREOF, I have made and executed this certificate this day of 19. Town Attorney Wrightsville Beach, North Carolina - zS 22 TOWN OF WRIGHTSVILLE BEACH STATEMENT OF FINANCIAL CAPABILITY AND FINANCING PLAN BEACH EROSION CONTROL AND HURRICANE PROTECTION PROJECT WRIGHTSVILLE BEACH, NORTH CAROLINA STATEMENT OF FINANCIAL CAPABILITY The Town of Wrightsville Beach (hereinafter referred to as the "the Town"), as non-Federal sponsor of the Beach Erosion Control and Hurricane Protection Project at Wrightsville Beach, N. C., is capable of meeting cost sharing and other obligations as required under the terms of the draft Local Cooperation Agreement. Through use of finance mechanisms that are politically and institutionally plausible, the Town will be prepared to meet the financial obligations of the project's non-Federal sponsors. FINANCING PLAN Uses of funds. The Town will be responsible for 35 percent of the total project costs. Included in the Town's share are all lands, easements, rights-of-way, dredged material disposal areas, and relocations (LERRD) determined by the Federal Government to be necessary for construction and maintenance of the project; such LERRD must be furnished to the Federal Government prior to the advertisement of any construction contract. Construction is projected to begin early in calendar year 1990, preferably no later than February 1. The construction period is estimated to be three months. The estimated cost of the renourishment assigned to the Wrightsville Beach project is $1,047,600, of which the Town is responsible for approximately $366,700 cash, to be paid during construction. Annual expenses to the Town for operation and maintenance of the project (vegetative maintenance of the dune) are estimated to be $4,900. Sources of Funds. The Town has requested $200,000 from the State of North Carolina (hereinafter referred to as "the State"). North Carolina General Statutes 143-215.70 through 215.73 allow the State to participate in beach renourishment projects up to an amount not to exceed 75 percent of the non-Federal share of the cost of the project. Although confirmation of the State's participation in this project cannot be provided at this time, the State does have a long history of strong commitment to-similar projects. The State has demonstrated this commitment in its financial assistance in the past to Federally initiated and maintained projects at Wrightsville Beach and Carolina Beach. The Town will procure a financial commitment from the State. /4-2/ The Town has $80,000 cash available from its general fund and the remainder of the local sponsor's share of the project cost will be requested from the proceeds of the New Hanover County Room Occupancy tax, 75% of which is designated by state law for use in controlling beach erosion. The Town will have $4,900 available annually from its general fund operating budget for operation and maintenance of the project. 11; - -1.

This document supplements the Environmental Assessment and Finding of No Significant Impact (EA/FONSI) for the Continued Federal Participation in the Wrightsville Beach Shore and Hurricane Wave Protection Project, New Hanover County, North Carolina,-which is included in the Feasibility Report dated September 1982. As a result of the feasibility report, the Wrightsville Beach project was reauthorized by the Water Resources Development Act of 1986 :9bs tai gg?-Sderal cost sharing for beach nourishment for the - life of the project. The study area is s_iowb on _itgure-- 1. The purpose of this supplement to the EA/FONSI is to assess the impacts of expanding the Masonboro Inlet/Banks Channel sediment trap/borrow areas and placing the material from these areas on Wrightsville Beach. All other impacts of the project are-addressed in the EA/FONSI referenced-in the previous paragraph and will not be repeated herein. Expanding the two sediment trap/borrow areas is necessary to increase the amount of suitable borrow material available for renourishment of Wrightsville Beach during the FY 90 renourishment event and during future nourishment events. 2. PROPOSED ACTION. The Masonboro Inlet and Banks Channel sediment trap/borrow areas will be expanded to include an area approximately 1,250 feet long by 875 feet wide at the confluence of Banks Channel and the Masonboro Inlet Channel and an area approximately 600 feet long by 600 feet wide near the seaward end of the Masonboro Inlet South Jetty as shown on Plate 3. The Banks Channel sediment trap/borrow area, including the 1,250 foot by 875 foot expansion, is referred to as Borrow Area B and is dredged to a depth of -30 feet mean-low-water (mlw). The Masonboro Inlet sediment trap/borrow area is divided into two sections, Borrow Areas A and A' and is dredged to a depth no greater than -20 feet mlw to avoid impacts to existing archeological/historical resources. The 600 foot by 600 foot expansion is located at the eastern end of Borrow Area A'. 3. ENVIRONMENTAL EFFECTS. The discussion concerning the environmental effects of the expansion of the sediment trap/borrow areas on affected resources are the same as those described in the previously referenced EA/FONSI except as stated below: a. Water Quality. The material within the sediment trap/borrow areas consists of high quality beach sand which enters the system from Masonboro Inlet and is suitable for placement on the beach. The discharge of fill material on Wrightsville Beach is covered under water quality W certifications number 1393 issued April 30, 1980, and number 1393-R issued September 30, 1980. The Section 404(b)(1) Evaluation Report and Finding of Compliance for the.pro,ject are included as Appendix G of the Feasibility Report and EA/FONSI, dated September 1982. The expansion of the areas does not alter the findings in the Section 404(b)(1) Evaluation Report and Finding of Compliance. These documents will, therefore, not require revision. 1 -2004-6-1 rees. The expansion of the sediment trap/borrow areas has been reviewed or areieo3h.: concerns. The magnetic surveys of Masonboro-Inlet, Masonboro Channel, and Banks Channel, conducted in the late 1970's, indicate thatno effect to known cultural resources will occur in the expansion areas, as long as the Masonboro Inlet sediment trap/borrow areas are not dredged below -20 feet mlw.- A magnetic anomaly was identified in Masonboro Inlet area at -25 feet mlw. No cultural resources were identified in the Banks Channel sediment trap/borrow area, Borrow Area B, during the survey. c. Coastal Management Program. The expansion of the sediment trap/borrow areas is consistent with the approved Coastal Management Program of the State of North Carolina. This supplement revises the existing consistency determination (Appendix F of the Feasibility Report and EA/FONSI, 1982) dated July 28, 1982. State concurrence was received on September 17, 1982. d. Endangered Species. The expansion of the sediment trap/borrow areas will not jeopardize endangered species or their critical habitat or violate the protective measures for any marine sanctuaries. Reinitiation of formal consultation with the U.S. Fish and Wildlife Service has been requested to include the potential impacts of beach disposal on wintering piping plovers and transient roseate terns, and to allow placement of fill material on the beach during the sea turtle nesting season in 1990 and during future renourishment events, if it becomes necessary. 2 4. COORDINATION. Agencies Contacted. Representatives from the following agencies were contacted regarding the proposed action: U.S. Fish and Wildlife Service, Raleigh, North Carolina Mayor, Town of Wrightsville Beach Notice of Availability. A notice of the availability of the Supplement to the EA/FONSI will be mailed to all concerned Federal, State, and local agencies and the public: 5. FINDING OF NO SIGNIFICANT IMPACT. f -The proposed expansion of the sediment trap/borrow areas will not significantly affect the quality of the human environment; therefore, an environmental i act statement will not be prepared. a ence W.
