Matthews, Jr., Manager 2645 Temple Point Rd. Havelock, NC 28532 (252) 444-1805 Engineer: Stroud Engineering, P.A. 151-A N.C. Hwy.24 Morehead City, North Carolina 28557 (252) 247-7479 A. Description of Project Type of Development Morehead City Yacht Basin project is located in the Town of Morehead City, Carteret County, N.C. on a tract of land located off Highway 70 West on Calico Bay. The proposed project consists of new parking design to accommodate a previously approved marina. This project has previously been approved under redevelopment by the Division of Water Quality on May 23,2002 #SW8 011002. The previously approved plan would not function as designed, therefore a new design has been proposed. We are still proposing to utilize sand filters as the "BMP", however, they have been relocated and two stormwater lift stations have been added to move the water to the required 30' vegetative swale at the most eastern portion of the property. 2. Earth Disturbing Activities a. Excavation and grading for the installation of the drive and parking area, drainage, and utility improvements, and stormwater treatment systems. Drainage The site presently drains north to Calico Creek, Class "SC", by sheet flow and by the town's existing storm drainage system. B. Erosion and Sedimentation Control Measures The following measures are proposed for the site. If it becomes evident that additional erosion and sedimentation control measures are needed, they shall be installed immediately. It is intended that all grading and excavation activities within a certain area will be protected as soon as that activity is complete. 1. Sediment Fence - Sediment fence will be utilized as necessary in locations as shown on plans or as deemed necessary by the engineer to insure that off -site sedimentation in controlled. 2. Sediment Storage- Stormwater sand filter systems proposed for the site will serve as sediment storage areas during the construction phase of development. 3. Seeding - All disturbed areas will be seeded within 14 days following construction in accordance with the seeding schedule shown on plans. 4. Stone Construction Entrance — The present means of ingress/egress from this property are currently paved. Once asphalt is removed a stone construction entrance will be required. C. Construction Sequence 1. Construct bulkhead. 2. Construct sand filters and vegetative filter. Immediately after construction of vegetative filter, sod using centipede sod. 3. Remove existing asphalt as required and rough grade site. 4. Install stormwater lift station and all associated piping. 5. Fine.grade parking areas and place stone base course. 6. Pave parking areas. 7. Perform final grading, seed and mulch all remaining disturbed areas within 14 days of disturbance. D. Design Assumptions 1. Design storm is ten years. 2. The rational method was used for design. 3. The sand filters are based on design criteria found in the NCDENR-Division of Water Quality "Best Management Practices" manual. E. Sand Filter System Operation and Maintenance a. The sand filter units shall be inspected after a storm every three months to make sure the filters are passing the runoff as expected. During the inspection, all vegetation growing on the surface of the filter shall be removed and check and clear the overflow weirs of any obstructions. b. The sand filter shall be replaced if inspection shows that runoff is not passing through the sand within 24 hours. Replacement shall entail removal of the top two or three inches of discolored sand and replacing with new sand. c. Maintenance of the sediment chamber shall be performed at same time of sand filter inspection. If sediment depth is over half the depth of the sediment chamber (15 inches), the sediment shall be removed. It may be necessary to de -water the sediment before it is acceptable at a landfill. d. If the Division of Water Quality determines that the system is failing, the system will be immediately repaired to its original design specifications. If the system cannot be repaired to perform its design function, other stormwater control devices as allowed by NCAC 2H.1000 must be designed and constructed. F. Coastal Stormwater Regulations The North Carolina Division of Environmental Management implemented coastal stormwater regulations in coastal counties on January.1, 1988. These regulations are detailed in 15 NCAC 2H.1000 Stormwater Runoff Disposal. These rules allow for a development to be considered under various options. This project is submitted for approval consideration under Section .1003(d)(3)(B). `01111111111�,I .0- GARp� • � L Z Z� " �o?o��ssroti...q Ronald D. Cullipher, P.E.

The plans show the 6" pipe going straight to the catch basin to be released directly into the receiving stream. As we have discussed, systems within 112 mile of SA waters may not discharge directly. ALL flows from the system must be directed into a vegetated filter prior to release into the receiving stream. You will need to figure out a way to get the runoff from the 6" pipe into the vegetated filter. You still refer to and label the required vegetated filters as grassed swales on the plans. As previously indicated, the vegetated filter is not simply a grassed swale to transport runoff from Point A to Point B. Please relabel. The BMP design requirements indicate that the minimum orifice size from the sand filter must be 6". PIease provide a minimum 6" orifice and calculations which demonstrate that the selected orifice will drain the sand filter within 24 hours. S:1WQSlS'I'ORMWATIADDINF0120021011002.APR N.C.

PROJECT SUMMARY: The applicant is proposing to reconstruct and expand an existing commercial marina known as the Morehead City Yacht Basin, Inc. Field Investigation Report Morehead City Yacht Basin, Inc., c/o Mr. William Vanderwall Page 02 9. NARRATIVE DESCRIPTION: The applicant is Mr. William Vanderwall, doing business as The Morehead City Yacht Basin, Inc., in the Town of Morehead City. The site is located adjacent to a channel of the Newport River known as Calico Creek Channel, on the northwest side of the US Highway 70 high-rise bridge over the Newport River. The property abuts the NC State Ports property to the west and has a street address of 208 Arendell. This proposal is for the reconstruction and expansion of a commercial marina, and is subject to SEPA requirements. An EA for the project has been reviewed under the SEPA, and has cleared the State Clearinghouse. The western half of this property has been developed in the existing manner for +50 years, and consequently, the existing conditions are mostly that of a disturbed and impervious nature. The width of the property was reduced with the widening of Highway 70, and consequently the entire high ground of the property lies within the Coastal Shoreline AEC. The property is 1.03 acres in size, and ranges from 5-7' above msl. The situation with the property line on the western is somewhat strange, given to the fact that a business known as Sea Tow straddles the property line. The applicant has recently purchased the eastern half of this property for the expansion of his facility. Consequently, the newer portion has never been developed, and is largely undisturbed and pervious in nature. The high ground portion of the property from midway west is mostly asphalt, concrete, buildings, and gravel. From midway east, there is a fringe of S artina alterniflora marsh, leading to a buffer of shrub/scrub habitat, predominantly cedars and wax myrtles, and cleared vegetation within the Department of Transportation Right of Way. At the western terminus of this portion of the property, there has been. an attempt at stabilizing the shoreline where scouring has occurred intersecting the bulkhead of the remainder of the property. This consists of concrete rubble. The property west of this has been stabilized by bulkhead. The existing marina consists of limited parking, a ship's store, two docks with fuel service, and 43 wet slips. The largest slips are 55' in length. The public trust incorporation associated with the existing docking system is approximately 87, 400 square feet, or +2 acres. The current marina policy is for daily, weekly, monthly, and yearly leases, with short term transient docking, and no live-aboards. However, site inspections show evidence of live-aboards, such as canopies over the docks with seating areas, picnic tables, and several grills and cookers. The area around the existing marina has been historically excavated and maintained. This basin area extends to approximately 60' east of the easternmost point of the docks. Water depths in this area range from -5' to -8' nlw. The water depths adjacent to the newly purchased portion of the property range from 0' to -2.6' nlw, and do not indicate past excavation. The application states that this area was the main portion of the Calico Creek Channel prior to the filling that occurred for the construction of the NC SPA facility. While this may be true, it does not indicate that the area was excavated previously. The applicant supposes that this area was excavated in a mining effort for material to fill the site of the NC SPA property. While this is logical, it is supposition. There is no evidence that the eastern half of this site has been excavated, and consequently any dredge request in this area must be considered in terms of new impacts. There is a 70' federal channel within the Calico Creek Channel, terminating at the US Coast Guard facility to the west of the Field investigation Report Morehead City Yacht Basin, Inc., c/o Mr. William Vanderwall Page 03 project site. The Town of Morehead City Land Use Plan for the project area is Developed, with all AEC's classified as Conservation. The DWQ classifies this portion of the Newport River as SC. The Division of Health Services has closed the area to the taking of shellfish for consumption. The area is not designated as a Primary Nursery by the DMF. Municipal water and sewer presently service the site. The body of water at the project site is approximately 740' across. The zoning classification for this area is Commercial Marina Downtown. The proposal is for the redevelopment and expansion of this facility. The applicant proposes to increase the impervious area within the Coastal Shoreline AEC to 43.7%, by placing marl, gravel, and concrete to meet the town parking requirements of .5 spaces per slip. Submitted with the document is an innovative stormwater design engineered to meet the intent of the 30% impervious requirement in the AEC. This aspect of the proposal will result in 44 parking spaces, 9' x 18' in size. The two existing docks will be removed, and four docks will take their place. Because the configuration of the basin is essentially square, water access from the properties to the east and west must be allowed. The application has submitted a riparian corridor design beginning at an apex at the center of the basin, horizontally, and located waterward at a point on the federal channel setback. This corridor is triangular, extending from the apex to the property lines on either side at the nhw contour. The applicant has exploited the entirety of the corridor without breaching the 15' setback from it. The proposed docks are to be 10' in width, with the western dock extending 357', the dock to the cast of this extending the farthest, 570', the next to the east extending 383', and the easternmost extending 180' . There will be 41 finger docks extending from these 4 main docks, each 5' in width. The lengths will vary from 50'-82', with 72 mooring pilings to supply a total of 78 slips. These slips will support mixed type boats ranging from 50' to > 100'. The footprint of public trust incorporation by the new proposal will be approximately 217,300 square feet, or ±5 acres. The ends of the 3 main docks will all have a pumpout facility and fuel service. A new double containment underground fuel storage tank is proposed under the parking lot, and is still being reviewed by the Division of Waste Management. The applicant proposes to maintenance excavate by hydraulic dredge the 7.63 acres of bottom habitat to the west that has been historically maintained. This area currently averages —5' to —8' nlw, and will be excavated to —5' at the bulkhead to —10' at the intersection with the federal channel. Also proposed is the new excavation of the eastern side of the waterbody. This area is approximately 2.17 acres in size, and presently sounds at 0' to —2.6' nlw. The same finished contours apply. The excavation proposal will disturb 9.8 acres of bottom habitat, with 2.17 acres of this being shallow bottom currently. The project will remove approximately 58,937 cubic yards of material from the system, based on the submitted soundings. The bottom material has been tested for placement in the NC SPA facility, and did not pass the required size analysis. Bottom sediments consist primarily of fine silts, and proved in testing to contain years of marina deposition making it oily. There is an area at the northeast point of the property indicated by crosshatching. This does not represent an area destined for dredging, but the location of an oyster bar. A minimum of 25' has been left undisturbed on the proposal between the marsh and the area to be excavated. None of the area to be excavated involves wetlands, submerged vegetation, or Field Investigation Report Morehead City Yacht Basin, Inc., c/o Mr. William Vanderwall Page 04 evidence of a shellfish resource. The applicant has leased from the NC SPA the area to the immediate' east of the property for temporary spoil placement. While the application states that this area is 4 acres in size, the proposed plat shows it to be approximately 3.46 acres in size. Dike walls are to be constructed with material hauled to the site. The walls are to have a 20' bottom width and a 2' top width, with 3:1 side slopes. The walls will have a 5' inside height, with V designated as freeboard. This leaves an inside spoil area of 2.2 acres, with a storage capacity of 14,356 cubic yards. The influent pipe will enter the facility on the east side of the basin, with the effluent pipe entering the creek to the north of the NC SPA property. Stormwater and Sedimentation/Erosion Control Plans have not been submitted for this project, but are known by the applicant to be necessary. 10. ANTICIPATED IMPACTS: This site has been utilized for this same purpose for many years. The expansion proposal will increase the public trust incorporation by the project from 2 acres to 5 acres, and the elimination of shallow bottom habitat from 7.63 acres to 9.8 acres. The proposal will require the disturbance of 9.8 acres of bottom area during the removal of 58,937 cubic yards of material. The connecting water depths are sufficient to support the proposed depths. Turbidity can be expected during the hydraulic excavation. The numbers of vessels using the facility will increase from 43 to 78, with additional transient dockage along the 4 outer docks. Vessel sizes will also increase. A pumpout will be made available, with ease- of access by availability in three locations. Fuel services available in one site presently will be available in three locations. The spoil area is insufficient in size for the amount of material to be placed there. There is approximately four times the material destined for the spoil site than it can contain. While the applicant proposes to haul the material to property east of Beaufort, this may not be a practical alternative. The material to be placed in the spoil area is very fine and oily, and not conducive to drying quickly. The material would have to be deposited, allowed to dry for weeks or months before removal, and re -deposited 3 or 4 times. The cost of keeping a contractor mobilized for this period of time, or to re -mobilize several times will be prohibitive. The potential then is for the applicant to push the envelope with regard to filling the spoil area, causing a breach of the dike wall, or turbid material being dispensed through the effluent pipe. The finished impervious area for the high ground portion of this project exceeds that allowable. However, this has been mitigated by an innovative design stormwater plan for the AEC. Assuming the system is installed and maintained, impacts should not be prohibitive. Ingress and egress from this parking area is hazardous, due to the proximity of the parking area to the highway and the bridge. While the location is unavoidable and the use exists currently, safety is a consideration in the proposed expansion. T. Barrett October 19, 2001 1NIorehead City MARINA IMPROVEMENTS MOREHEAD CITY YACHT BASIN CARTERET COUNTY PROJECT NARRATIVE OCT Z��1 June 8, 2001 Rev. October 5, 2001 „ .. INTRODUCTION The existing marina has been in operation in basically the same dock configuration since the 1950's. The existing marina consists of 43 slips ranging from 35 feet to 60 feet, fuel facilities on the main dock, and a Dock Master building with a small ships store, restroom, showers, and laundry facilities. The existing building is being improved, but the size of the building will not be increased. The project is located in Carteret County within the town limits of the Town of Morehead City on Calico Creek on the Newport River Estuary (see sheet 1). The yacht basin is located between the U. S. Army Reserve Basin facility and N. C. State Port Authority property on Highway 70 at the eastern end of Morehead City (see sheet 2). PROJECT DESCRIPTION The project consists of the following elements: • Demolition of existing docks and construction of fixed timber docks supported by piles and/or floating docks anchored by concrete or steel guide piles. • Replacement of 43 existing slips and construction of 35 additional slips. The new and replaced slips will result in a total of 78 slips in the completed facility. The boat slips will be constructed to accommodate boats from 50 to over 100 feet in length. • Electric, communications and potable water utilities will be provided for each slip. • Expansion of the fuel storage capacity and replacement of fueling facilities at several locations on the new docks. • installation of pumpout facilities will be added to the marina with'several service points on the docks. Sewage from the pumpout facilities will be pumped to the Town of Morehead City municipal sewer system. Dredging of approximately 43,000 cubic yards of silt and fine sand from the marina basin to a temporary confined disposal area on Port property adjacent to the site. Existing and proposed bottom contours are shown on the dredging plan on sheet 7. • Demolition of concrete walks to reduce impervious surfaces and construction of additional parking areas to accommodate a total of 44 vehicles. • Installation of stormwater treatment facilities to treat runoff from impervious areas in excess of the 30 percent allowed within the AEC. The marina slips will be leased to boat owners on a daily, monthly and annual basis, and will also cater to transient boats. Live -a -boards will not be permitted and there will be a closed head policy for boats using the marina with the pumpout station available for use by occupants of the slips and other boaters using the adjacent waterways. Morehead City Yacht Basin Improvements June 8, 2001 Major CAMA Permit Application — Narrative Rev. 10/5/01 Page 1 OCT 0 8 2001 EXISTING CONDITIONS The project area is located adjacent to the downtown area of the Town of Morehead City on lands owned by the applicant, Morehead City Yacht Basin, Inc. The areas south and east and north of the marina basin are densely developed industrial and military port facilities. The marina site is bounded on the south by U. S. Highway 70 east. Relocation of the roadway in the 1960's reduced the size of the upland areas at the marina. The southern portion of the existing marina basin is bordered by approximately 620 linear feet of concrete sheetpiie bulkhead. Elevations of the bulkhead cap and adjacent upland areas are generally 5.5 to 6.5 feet, NGVD (see sheet 5) The onsite upland areas adjacent to the existing marina basin consist of concrete and asphalt paved sidewalks, parking areas and decks at the Dockmaster building. Upland areas of the eastern half of the southern margin of the site consist of a gravel parking area with the remainder grassed with small scrub oaks along the edge of the marsh. All upland areas in the project site are in the Estuarine AEC, within 75 feet of the mean high water line. PURPOSE AND NEED FOR THE PROJECT The Morehead City Yacht Basin is one of the original marinas in the Morehead City area. The existing docking facilities and structures are at least fifty years old, far beyond the economic life of such structures. Land areas around the marina are currently used for heavy industrial waterfront and military waterfront activities. The existing marina facilities are in poor condition and must be upgraded to make the facility competitive with newer marinas in the Morehead City and Beaufort area. In order to make the marina economically viable, additional slips must be added. Adding slips and upgrading existing marina facilities is preferable to building new facilities in previously non -impacted areas. Historically, the Morehead City Yacht Basin has catered to large boats transiting the Atlantic Intracoastal Waterway and offshore Atlantic Ocean adjacent to Carteret County. The improvements proposed will permit the marina to better serve this large boat clientele. The project also includes replacement of fuel systems and installation of sewer pumpout facilities on the docks. The Yacht Basin facilities are in an area where adjacent waterfront uses are heavy port industrial and military waterfront activities. Upgrading the marina with modem docking facilities, fuel storage and delivery systems, treatment of stormwater from upland impervious surfaces, and installation of sewer pumpout facilities will reduce overall environmental impacts caused by the existing marina and prevent additional impacts to other pristine coastal resources in Carteret County, MARINA ALTERNATIVES Alternatives to the proposed marina construction were considered. A. Upland Marina Basin Excavation of basin area for additional upland marina basin area outside the public trust waters is not a viable option forthis project. No adjacent lands are available to accomplish this option. B. Dry Storage Marina The proposed project is expansion of an existing floating marina in a previously impacted area. There is not adequate upland area for construction of a dry stack marina facility. C. Replacement of 43 Slips, Construction of 35 Additional Slips, Dredging of 43,000 Cubic Yards. Morehead City Yacht Basin Improvements June 8, 2001 Major CAMA Permit Application — Narrative Rev. 1015101 Page 2 OCT U 8 2001 The proposed project involves replacement of 43 existing slips and construction of 35additional slips. The new and replaced slips together will represent a total slip count in the completed marina of 78 slips. Sheet 6, the Project Site Plan, shows the proposed layout of the new marina facilities. The project also involves dredging of 43,000 cubic yards of fine sand and silt to a temporary confined disposal area on N. C. Port Authority property adjoining the marina. The project includes replacement of fuel systems and installation of sewer pumpout facilities on the docks. The Yacht Basin facilities are in an area where adjacent waterfront uses are heavy port industrial and military waterfront activities. Upgrading the marina with modem docking facilities, fuel storage and delivery systems, treatment of stormwater from upland impervious surfaces, and installation of sewer pumpout facilities will reduce overall environmental impacts caused by the existing marina and prevent additional impacts to other pristine coastal resources in Carteret County. STORMWATER MANAGEMMENT An innovative system is proposed for the site because the impervious area on site exceeds the 30 percent allowable within the AEC. Components of the system are shown on the Site Plan (sheet 6) and details on sheet 10. Calculations for the system are attached. MAINTENANCE DREDGING The basin adjacent to the existing docks has been maintained by dredging. The remainder of the area to be dredged has not been dredged recently. Evidence is provided with this application showing that the area proposed for dredging has been maintained as a navigation channel in the past. Sheet 3, an old oblique aerial photograph obtained from the N. C. Port Authority, shows that, before the relocation of Highway 70 and construction of the filled port lands east of the site, the Calico Creek Channel alignment went through the eastern half of the existing marina basin. The date of the photo is approximated as 1963 or before. It is believed that the eastern portion of the existing basin was excavated for fill of the high ground N. C. Ports property east of the site. Sheet 4, a 1995 aerial photograph, shows the marina and surrounding area as it is currently developed. Comparison of the two photographs shows that the old channel went through what is now the Port property east of the site. Samples of the material to be dredged were collected and analyzed to determine levels of contaminants that might exist in the sediments. Bottom sediments are predominately fine sand and silts. Chemical and sediment size analyses were performed for three core samples collected in the area to be dredged. The three samples were combined into a single composite sample for chemical analysis. The tests were performed in accordance with N. C. State Ports Authority, "Criteria for Evaluating Dredged Material Proposed for Placement in the North Radio Island and Brandt Island Confined Disposal Facilities." A copy of the chemical and sediment size analyses report is provided in Appendix A. The project involves hydraulic dredging of 43,000 cubic yards of fine sand and silt and pumping to a temporary confined disposal area. Dredged material will be pumped to a temporary containment area on N.C. Port Authority property adjoining the east side of the marina. The land to be used as a temporary dredged material disposal area is bordered on Calico Creek by riprap shore stabilization. The land is currently undeveloped and consists of grassed and gravel surfaces. A soil dike 4 feet high will be constructed on the Port property from material on the site and material hauled to the site from an offsite borrow area. Any borrow material required for dike construction will come from Sea -Rise Mining and Fanning, a permitted sand mine in Betty, North Carolina (east of Beaufort). The dewatered dredged material will be mixed with the soil in the dikes and returned to the Sea Rise Mine where it will be used as fill for open pits that the owner wishes to fill for farming and or resale as fill material for other uses. Availability of the fill material for dike construction and of the Sea Rise site for disposal of dredged material has been confirmed with the owner of Sea Rise Mining and Farming, Mr. Tommy Trevethan. Morehead City Yacht Basin Improvements June 8, 2001 Major CAMA Permit Application — Narrative Rev. 10/5/01 Page 3 OCT 0 6 2001 Existing and proposed depth contours are shown on Sheet 7, the Dredging Plan. Cross -sections of the marina basin showing before and after bottom profiles are shown on sheet 7A. Sheet 8 shows the location of the temporary disposal area and the probable locations of slurry and outfall pipes to the disposal area. The N.C. Port Authority has agreed to lease the property adjacent to the marina for use as a temporary disposal area. A letter from the N. C. Port Authority agreeing in principal to lease the property is attached in Appendix B. A lease agreement has been developed and is currently being reviewed by the Port and the applicant. A copy of the lease can be made available to the Division of Coastal Management upon request. METHODS OF CONSTRUCTION Several marine construction techniques will be employed for completion of the project. The dredging methods are described in the "Maintenance Dredging" section of this Narrative. Dock construction will involve pile driving using both jetting and driving of piles. Pile materials will be a combination of treated timber, square concrete and cylindrical steel, Pile driving will be done by barge -based pile driving equipment. Floating docks will be of either concrete or timber construction with floatation provided by either vinyl or concrete floatation units. Floating dock units will be factory fabricated and delivered to the site ready for installation. No fabrication of floating docks will take place at the site. Fixed docks will be fabricated entirely at the site of final location. Materials will be treated timber framing on treated timber piles. Dock utilities will be fed from shore and enclosed in the fixed and floating docks. No utilities will be buried in the marina bottom. PROJECT SCHEDULE After the required CAMA Major permit is obtained, construction of the project, including maintenance dredging and dock construction, will require from six to nine months. COMPLIANCE WITH TOWN OF MOREHEAD CITY ZONING AND CAMA LAND USE PLAN Current zoning of the marina property by the Town of Morehead City is CMD, Commercial Marina Downtown. Boat slips and fuel storage are a permitted use in the CMD zone. The Town of Morehead City requires that open water marinas provide parking spaces on the ratio of 0.5 parking spaces per slip plus employee spaces. The parking or the project meets that criteria. The proposed project will not change the use or conflict with the current zoning of the upland land areas. The project is in compliance with the zoning and CAMA Land Use Plan for the Town of Morehead City as updated and adopted on May 28, 1999. COMPLIANCE WITH THE N. C. ENVIRONMENTAL POLICY ACT Construction of the marina improvements will be done with private funds in the Public Trust Waters of the State of North Carolina and will comply with the requirements of the State Environmental Policy Act. An Environmental Assessment has been prepared, reviewed and accepted by the N. C. Division of Coastal Management. The EA was submitted for Departmental Review on April 4, 2001, The applicant is awaiting review comments as of the date of this application.
