The proposed club is located adjacent to Little Creek, which is an inland tidal creek, and Porters Neck Plantation. The site is located immediately southwest of the intersection of Porters Neck Road and Bald Eagle Lane in Harnett Township, New Hanover County. Current Conditions The 230-acre site is currently a large abandoned field and young woodland. The eastern portion of the site contains old man-made irrigation ponds. The ponds are connected by a wet weather drainage way. There are 8 separate wetland areas which include the existing ponds. Of the nearly 22 acres of on -site wetlands, the majority of these wetlands (approximatley19 acres) are located in one wetland area along the creek. Current vegetation consists of primarily grasses, scrub growth, and young trees. Subsurface soils in upland areas are generally well -drained. Heavy spring rains indicate the existing drainage has maintained groundwater levels at a reasonable depth so as not to preclude or interfere with proposed developments. Subsurface soils in freshwater ponds and wetlands are primarily poorly drained sands. Proposed Conditions The club will consist of an18-hole course accompanied a nine -hole short game. In addition, a clubhouse, four cottages, golf paths, maintenance yard, entry road and parking space are included in the project. The golf maintenance facility will be located off of Porter's Neck Road and will be screened from view. All amenities are for use by private members only. This low density development will be utilized by 200 to 250 members per year, and the members reside both inside and outside of North Carolina. No large promotional events are scheduled for the course. Proposed grading has been designed concurrently with stormwater management and sediment erosion control. More specifically, grassed lined water quality swales, sheet flow over dense grasses and natural ground cover, and on -site ponds will provide on -site runoff treatment including sediment control and nutrient take-up. At the property perimeter, various berms will create a screening effect from adjoining landowners. The new ridge lines will also ensure that stormwater runoff is retained on the interior of the site and any discharge from the site during major storm events will occur through one of two existing outfalls. In addition, the existing ponds will remain while the wet weather drainage way connecting these ponds will be expanded. Furthermore, two additional landscape ponds are to be created. Golf course operations will follow accepted industry standards and agricultural practices. Thus, all chemicals will be properly stored and handled to prevent spills, any spills will be properly contained and cleaned up, and only certified employees will apply registered chemicals. Wastewater is to be routed either into a septic system or county sewer. Potable water is to be provided either from on -site wells or the Porters Neck Plantation Water source. Irrigation water is to be supplied by on -site wells drawing water from the Castle Hayne aquifer. On -site testing has been performed to determine that efficient recycling will occur via percolation and recycling. 2- Aquifer flows will generally come from the west. Noticeable groundwater elevation drawdown at the property boundary will not be noticeable based on site studies. Only 1.32 acres of non jurisdictional, isolated wetlands will be impacted by the project. Mitigation, although not required for this impact, is proposed to consist of 2.46 acres of created freshwater marsh, a ratio of 1.76 acres of creation per acre of impact. 0.23 acres of the mitigation are for golf course impacts and 1.09 acres are for conversion of woody wetland to freshwater marsh. Current On -Site Study/Permit Status - The property has been designed to adhere to the following regulatory setbacks: 575' setback (AEC) from the Mean High Water. 75' setback from New Hanover County C.O.D. (no impervious) 30' setback from Mean High Water for CAMA and DWQ (undisturbed) - A comprehensive archaeological survey is being conducted and coordinated with SHPO. - A RCW (red -cockaded) woodpecker survey is being conducted. - A wetland delineation has been certified by the COE. - A water resource evaluation for water supplies has been completed. - A Land Disturbance permit/Soil Erosion Control Plan has been submitted and received. - A stormwater permit application was submitted on June 26, 1998 and is currently being reviewed by the appropriate agency personnel. 1412/cama narr & fact sheets.doc EAGLE POINT GOLF COURSE FACT SHEET PROPERTY LOCATION LATITUDE 34 17 00 LONGITUDE 77 45 30 PROPERTY OWNER PROJECT TEAM SITE LAYOUT CONSULTANT WETLAND DELINEATION CONSULTANT ARCHAEOLOGY CONSULTANT RED -COCKADED WOODPECKER CONSULTANT DESIGN/ENGINEERING CONSULTANT EXISTING CONDITIONS Eagle Point Golf Club, LLC COMPANY Fazio Golf Course Designers, Inc.

The plan was developed in association with a.CAMA major permit. Compensatory mitigation will consist of the creation of 2.46 acres of freshwater marsh; a ratio of 1.86 acres of creation per acre of impact. The created wetlands will be monitored for a period of five years. Even though the created wetlands will meet mitigation requirements, additional 5'-15' littoral shelves will be created around golf course lakes where topography and other concerns will allow. IMPACT ASSESSMENT The development plan (Figure 2) shows impacts to 1.32 acres of isolated, non - jurisdictional wetlands. Of these impacts, 0.23 acres are for golf course impacts and 1.09 acres are for conversion of woody wetland to fresh water marsh. Thus the majority of the impacts will merely shift the impacted wetlands from one classification to another. All impacts are to isolated wetlands, no impacts to jurisdictional wetlands are proposed. Therefore the wetland impacts will not impact wetland biogeochemical functions. MITIGATION Wetland mitigation will consist of freshwater marsh creation along the golf course. Three creation areas containing a total of 2.46 acres are shown in Figure 2. L The final mitigation ratio is 1.86:1. MITIGATION REQUIRED Since none of the proposed impacted wetlands are under Corps jurisdiction, DWQ mitigation ratios were utilized. DWQ mitigation criteria based on distances from surface water. Distances were measured from mean high water. Table 1 illustrates the process in which actual required acreage was determined. Total impacts of 1.32 acres were determined to require 2.33 acres of mitigation; a 1.76:1 ratio. HYDROLOGICAL CREATION The creation areas will be excavated to acceptable engineering grades to allow for marsh restoration. Strippings from the impacted areas will be saved and placed in the creation areas to allow for a more suitable organic substrate. VEGETATION CREATION The goal of vegetation establishment is the creation of homogeneous stands of vegetation along a water depth gradient with the deepest water occurring in the center of the marsh, with a gradual decrease in water depths leading up to the edge of the wetland. An example of this gradient is shown in Figure 3. Pontedaria cordata will be planted in the middle of the marsh, Scirpus robustus in shallower water and Spartina patens near the edge. illustrations of these species are shown in Figures 4-6. A five foot upland buffer will be established with Baccharis halmifolia and Mlyrica cerifera. 7 LITTORAL SHELVES Littoral shelves will be created where possible around golf course lakes. Shelf dimensions will be dictated by topographic and golf considerations. Wetland plants will be established at densities and compositions to be determined by the golf course architect and course superintendent. MONITORING PLAN All creation areas will be monitored for five years or until the project is deemed successful. Monitoring efforts will concentrate on hydrology and vegetation establishment. Annual monitoring reports will be submitted to concerned agencies. Each report will consist of a simple narrative with data analysis and reports on both success and problem areas. Photographs of each creation area will be included. Monitoring will be terminated once the project has been deemed successful. If the project is not deemed successful at the end of five years, a contingency plan will be implemented with the assistance of all concerned agencies. HYDROLOGY Three RDS WL-40 monitoring wells will be installed as shown in Figure 6 and will have one reading per day. The success goal of hydrology creation will be the establishment of a static water table at or within 12" of the soil surface for 5°%-12°% of the growing season during periods of normal precipitation. The success criterion will be the establishment of a water table at or within 12" of the soil surface for at least 5% of the growing season during periods of normal precipitation. VEGETATION Three 30'x30' vegetation plots will be established adjacent to each monitoring well. The vegetative cover of each well will be monitored using the coverage system described by Daubenmire (1968). The success criteria will be a 70% survival rate, including volunteer species, as measured by ground cover. MITIGATION IMPLEMENTATION SCHEDULE Weather permitting, the excavation and grading work will completed prior to the end of the next growing season after the plan and permit have been approved. The plantings will occur in the following dormant season. SUMMARY The applicant proposes to mitigate for the loss of 1.32 acres of non jurisdictional 404 wetlands with the creation of 2.46 acres of wetlands on -site. In addition, littoral shelves will be created around golf course lakes where possible. All wetlands impacted are isolated and non jurisdictional. The major wetland impact is the conversion of a depressionai woody wetland into a fresh water marsh with herbaceous vegetation. The wetlands will be planted based on a water depth gradient. All created wetlands will be monitored for five years. E LITERATURE CITED Daubenmire, R. 1968. Plant Communities: a Textbook of Plant Synecology. Harper & Row Publishers. New York.

A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: 1. Please provide a separate calculation for the area within the 575' AEC to demonstrate compliance with the 25 % low density required within the AEC. This can be done on the application in the second drainage basin column provided in Section III, No. 6. 2. Please be aware that due to the collection system currently proposed, any future subdivision of the land for development may not occur unless an engineered system is designed and permitted. Low density subdivisions may not have collection systems. 3. Per my meeting meeting on April 22 with Greg Hetzler, the piping was supposed to only be between the lakes, with OCCASIONAL low areas piped SHORT distances to a pond. The proposed plans shows lots of low areas that are collected via catch basins and long runs of piping. These areas must be minimized as much as possible. There is too much piping proposed to be considered a low density project. 4. Please provide elevations / proposed grading for the roads, parking lots and clubhouse. 5. Please provide dimensions for the clubhouse. 6. Please provide a road section detail. 7. There are no sidewalks shown from the parking lot to the clubhouse. Please add these with dimensions. Do you have a smaller scale drawing of the clubhouse and parking area?

Your concern is welcome. As you had noted, the project has received the Grading Permit from New Hanover County. Concurrently, the Stormwater Management Permit Application has also been submitted and is currently being reviewed by the State. To further update you on our permitting process, we have continued to involve the various environmental and regulatory agencies in the project. We have made a conscious effort to do this planning prior to submitting the CAMA Major Permit Application. We feel progress has been made in this direction by involving CAMA, Office Of State Archaeology, Division of Water Quality, COE, Fish & Wildlife, NHC etc. I just wanted to take this time and briefly summarize our verbal discussions concerning your important points which had been raised. To review these items, I have responded in the order if your letter. Environment: The Outstanding Resource Water (ORW) quality rating of Little Creek is a natural asset and deserves proper attention. It is in our design methodology to not only conform to the stormwater permit management criteria, but also to be aware of the Best Management Practices (BMP's). For your information, these were some of Ed Brooks', Coastal CAMA Representative, first concerns at our pre-CAMA permit meeting with him. Entrance Location: As discussed, the project is being designed with the premise that heavy patron traffic is not anticipated. In fact, one of the objectives of the founding membership is to allow for the benefit of non-scheduled Tee times. The access from Bald Eagle Lane minimizes length of driveways and affords an appealing vista to the club house. As traffic (players, not construction.) will be very low; the entry on Bald Eagle Lane is not expected to distract from the FXLERICAL1412\0001X081298jc Itr.doc 243 N. FRONT ST., WILMINGTON, NORTH CAROLINA 28401 TEI. 910.343.1048 FAX 910.251.8282 www.mckimcreed.com August 13, 1998 Page 2 neighborhood. In fact, by centering the drive within the adjacent owned lots, the entry can be better presented in the neighborhood while avoiding distractions on the adjacent lot owners. As we said, construction traffic is presently only permitted off of Porters Neck Road . Maintenance Building: As reaffirmed with you, Billy and Beau hear what your concerns are and are looking at relocation site possibilities for the Maintenance building. Regarding stormwater quality issues, we would proceed with obtaining a State stormwater permit and follow BMP's concerning normal operations. Zoning: All work within the property is being coordinated with the New Hanover County Planning Department. Compliance with zoning criteria is intended. Water Supply: Thank you for sharing personal history of local water well supplies. Our on -site water supply study has continued to progress. Our Hydrogeologist recognizes your concerns. Thank you for the time at the site. Please feel free to contact me should you have any further questions or comments. Sincerely, McKIM & CREED ENGINEERS, P.A. Gregory J. Hetzler, P. E.
