II) Master Stormwater Permit Application for Hadnot Point Areas 100 and 200 (Application)

A Master Stormwater Permit has been processed and issued by the NCDENR Regional DWQ Office in Wilmington. This permit is included in Appendix D of this report. The Master Stormwater Permit has been issued and serves to unify into a single permit the area both (1) existing/individual permits and

(2) future permits for new projects planned for the period 2010-2018 in the Hadnot Point Facilities Master Plan.

1. NATURAL RESOURCES INVENTORY AND ASSESSMENT

1.1. PROJECT LOCATION, TOPOGRAPHY AND FLOODPLAINS

1.1.1. Project Location

The Marine Corps Base Camp Lejeune (MCBCL) is located within Onslow County, along the coastal plain of North Carolina. The Base covers more than 153,000 acres that consist of approximately 26,000 acres of water and 127,000 acres of terrestrial features. Elevation at the Base ranges from sea level to 70 feet above mean sea level, with much of the site topography traversed by swales, wetlands, streams, and creeks that drain into the New River. The Base encompasses a 92-mile perimeter, including approximately 14 miles along the Atlantic Ocean, more than 450 miles of roads, 50 miles of railroads, one waste water treatment plant, five water treatment plans, and one active municipal solid waste landfill and one closed landfill. Camp Lejeune is home to an active duty, dependent, and civilian population of approximately 150,000. Hadnot Point accounts for approximately fifty percent of the working Camp Lejeune population. Hadnot Point 100-500 Areas are home to the 2nd Marine Division (2D MAR DIV) and elements of the II marine Expeditionary Force (MEF).

This Stormwater Master Plan focuses on two watersheds within Hadnot Point, identified as Areas 100 and 200.

1.1.2. Topography

Topographic mapping of the project site is shown in Figures 1, 11, and 17.

Area 100 comprises 99.2 acres draining north towards Wallace Creek. Elevations range from 26 feet above sea level (asl) to zero feet at the lowest point, which is the site where the watershed discharges into Wallace Creek. Slopes vary from almost flat in the areas south of A Street to steep slopes at the lowest areas of the watershed, north of Cross Street. Area 100 is subdivided into three regions with the following elevations and slopes:

South of A Street: elevations vary between 26 and 20 feet asl, except for a low spot at the west of the area with elevation 16 feet. Average slope: 0.9%.

Between A and Cross Streets: drainage is from the center and sides of the area (elevation ~22 feet) towards two creeks located east and west of the area (elevations ~4 feet).

Average slope: 3.5%.

North of Cross Street: drainage is from the center and sides of the area (elevation ~22 feet) towards the two creeks that ultimately converge and discharge into Wallace Creek.

Average slope: 9%.

Area 200 comprises 85.8 acres draining west towards the New River. Elevations range from 26 feet asl to zero feet at the lowest point, which is the site where the watershed discharges into the New River.

Area 200 is subdivided into three regions with the following elevations and slopes:

North of ―C‖ Street: elevations vary between 26 and 20 feet asl; there exists one low area to the west, which has an elevation of 14 feet asl. Average slope 1.2%.

Between C and D Streets: drainage is towards the west, elevations vary between 22 feet and zero feet (West of Julien Smith Blvd.), at the site of the discharge into the New River.

Average slope: 5.25%

South of ―D‖ Street: Elevations vary between 26 and 20 feet asl. Average slope: 1.2%

1.1.3. Floodplains

Areas of 100-year floodplain are located at the site of the discharges into Wallace Creek and the New River, at the northernmost section of Area 100 and at the westernmost section of Area 200, respectively. This 100-year floodplain is based on FEMA mapping. Limits of 100 year floodplain are shown in Figure 2.

1.2. WETLANDS

Tidal wetlands within the Study Area are regulated by the Coastal Area Management Act (CAMA). The Wetland Inventory identifies the wetland areas present in the Study Area, as shown in Figure 3, based upon the National Wetlands Inventory website, verified in December 2009.

o Wetlands in Area 100: A PFO1B wetland is present in Area 100, north of Cross Street, and extends towards A Street. The primary functions of this wetland are shoreline erosion protection, flood control, natural water quality protection, pollutant removal from stormwater runoff. As any other wetland, aesthetic value and fish/wildlife habitat is an additional attribute of this wetland area.

The following parameters defined the characteristics of the PFO1B wetland present in Area 100:

System: P: Palustrine

Class: FO: Forested

Subclass: 1: Broad-leaved Deciduous

Water Regime: B: Saturated o Wetlands in Area 200: There are no wetlands in Area 200.

1.3. GEOLOGY AND SOILS

1.3.1. Geology

As glacial events and slight crustal movements have changed sea level over the past 66 million years, the land base has been alternately exposed and submerged. Marine deposits laid down over time formed the weakly-dissected alluvial plain that Camp Lejeune occupies today. The deposits are mostly clean sand and clayey sand, layered with deposits of clay and marine shells. Along the coast, stream sediment deposition, and natural shore processes develop and maintain beaches, swamps, and mud flats.

The primary geomorphic surface at the Hadnot Point Areas 100 and 200 is the Pamlico surface, with elevations of 0-26’ in narrow strips along the Intracoastal Waterway, New River, and its tributaries.1

1.3.2. Soils

To describe the dominant soil(s) in the project area as well as any soil types that might prove to be a constraint to the proposed project, two sources of information were consulted:

USDA Soil Survey

In-situ soil investigation

USDA Soil Survey

Figure 4 and Table 1 summarize the soil types present within the Study Area, according to the USDA Soil Survey.

Well drained soils:

The most predominant soil type is the Baymeade-Urban (BmB) with 58% present in Area 100 and 83% in Area 200. Baymeade-Urban is classified as SM by the Unified Soil Classification.

These types of soil are characterized by good drainage (―A‖ Hydrologic Group) with the depth to the water table more than 1.0 meter.

Poorly drained soils:

Poorly drained soils are present near both discharge sites (~1%). Those soils are classified as Muckalee loam (Mk).

Soils information is detailed on the USDA Soil Survey and Results of Soil Investigation. More detailed soils investigations are included in Appendix A.

Soil Investigation

A soils investigation was performed by S&ME in the first week of November 2009 to assess potential sites for suitability of infiltration type stormwater BMPs. This soils investigation is included in Appendix A. The soil investigation included the following tasks:

In-situ soil hydraulic conductivity test at each seasonal high water table evaluation location for a total of eight tests. Hydraulic conductivity tests were performed using a compact constant head permeameter at depths recommended by the Government Services IPT Project Manager.

Evaluation of the seasonal high water table at eight locations as shown on enclosed map, to a depth of eight feet below the existing ground surface or until seasonal high soil wetness conditions are encountered (whichever is first encountered) as determined by, or under the guidance of a Licensed Soil Scientist.

Findings

In-situ soil hydraulic conductivity testing was performed by using a compact constant head permeameter at the test locations. Table 2 summarizes the results for each test location.

The seasonal high water table evaluations were performed on November 2 and 4, 2009, by advancing hand auger borings to depths ranging from approximately 29 to 88 inches below the ground surface at the test locations shown in Table 2.

Soils were evaluated under the guidance of a Licensed Soil Scientist for evidence of seasonal high water table influence. This evaluation involved looking at the actual moisture content in the soil and observing the matrix and mottle colors. Depending on the soil texture, the soil color will indicate processes that are driven by seasonally high water table fluctuations, such as iron reduction and oxidation and organic matter staining. A hand auger boring profile sheet which provides a description of the observed soil horizons and the determined seasonal high water tables has been included in the soil investigation report provided in Exhibit A.

18 March 2012

The soils at the test locations were observed to range from fine sand to silty clay loam. The seasonal high water tables were determined to be between 6 to 69 inches below the existing ground surface.

Table 3 summarizes the seasonal high water table depth at each test locations. These seasonal high water table evaluations are based on secondary evidence and not on direct groundwater level measurements. Potential indicators of seasonal high water table influence, mainly redoximorphic soil features, were observed in the fill horizons above the seasonal high water table depths determined by S&ME personnel. These features appeared to be relic based on their faded, non-distinct appearance and their location within the matrix of the soil not along soil ped faces or root channels.

1.4. LAND USE

The Study Area for this Stormwater Master Plan (Areas 100 and a section of Area 200 of Hadnot Point) complies with the planning principles established in the Facility Master Plan for the configuration of facilities within the Hadnot Point Areas 100-500 developed by Government Services IPT in 2009 (Figure 5). The 2009- Facility Master Plan addressed organizations affected by anticipated troop increases and organizations targeted for relocation to their designated Major Subordinate Command (MSC) area.

Consideration was given to the existing constraints and opportunities including Antiterrorism and Force Protection (ATFP) requirements, ground noise levels, transportation and utility corridors, Installation Restoration (IR) sites and management areas, hydrologic features, and historical buildings and districts.

The emphasis for Hadnot Point was to minimize demolition through the reuse of existing buildings, maintain operational efficiencies through unit integrity, resolve numerous ATFP standoff deficiencies and provide adequate privately-owned vehicle (POV) parking through surface lots and structured parking where necessary.

The Final Facility Site Plan primarily proposed reuse of existing buildings rather than demolition. The Hadnot Point Area (Areas 100-500) land uses are illustrated in the site plan in Figure 1. Current and proposed land uses of the Hadnot Point Areas 100 and 200 are described below.

From the preparation of the Facility Master Plan, consensus was reached on major decisions to be incorporated in the preferred Site Plan for the 100 and 200 Areas:

Provide facilities for one or two Infantry Regiments

Incorporate six-story BEQs and required parking at the location of the existing II MEF training facility, at the tennis courts north of Cross Street, and potentially on land immediately north of the 100 Area if necessary

Provide one Mess Hall to serve the combined 100 and 200 Area populations

Figure 5. Facility Master Plan: Hadnot Point 100-500 Areas

22 March 2012

1.5. LAND USES IN THE HADNOT POINT AREAS 100 AND 200

Facilities in Area 100 include the Infantry Regiment, Intel, and Radio BN; approximately 5,000 parking spaces, and 2,078 Bachelor Enlisted Quarters (BEQs). North of Area 100 is a dense mixed hardwood and pine tree canopy. Facilities in Area 200 include the Infantry Regiment, approximately 3,400 parking spaces and 1,700 BEQ rooms. A description of the facilities within Areas 100 and 200 follows.

Infantry Regiment - Hadnot Point 100-200 Area

Hadnot Point 100 Area and a portion of the 200 Area provide facilities for one Infantry Regiment.

Existing community facilities and associated parking include the fire station, new pool, Base Exchange, and theater. Buildings less suitable for preservation are proposed for demolition to provide some areas for strategic redevelopment. Older Mess Hall buildings and many of the small brick buildings (often used for storage or Indoor Simulated Marksmanship Trainers (ISMTs) are proposed for removal, replacement, or consolidation in new facilities.

Site Plan

The site plan maintains the existing land use pattern and vehicular circulation with a core of Bachelor Enlisted Quarters (BEQs) and operational facilities at the periphery. New BEQs are proposed north of the intersection of Julian C. Smith Boulevard and Cross Street. This will satisfy the deficiency in BEQ rooms for one Regiment. Due to the land constraints in the immediate area, two new three-story parking structures are proposed to meet the required quantity of POV parking. New Maintenance Shops are provided across from the existing Communications/Electric (Comm/Elec) Maintenance Shops on Cross Street to consolidate maintenance facilities to the maximum extent possible. New HQ CPs are proposed north of C Street in proximity to the existing BEQs. A new Mess Hall is proposed in a central location to all BEQs. A new ISMT to serve this area is proposed in the 2D MAR DIV Training Center in Wallace Creek.

Antiterrorism Force Protection

The 100 and 200 Area Site Plan corrects all ATFP standoff deficiencies for applicable buildings in this area with the exception of Buildings 119, 121, 123, HP125, and HP195.

BEQ Space

Required BEQ rooms are provided in existing buildings and three new five-story buildings north of the intersection of Julian C. Smith Boulevard and Cross Street. The existing BEQs provide 900 rooms in three-story configurations between Julian C. Smith Boulevard, A Street, McHugh Boulevard, and B and C Streets. The proposed BEQs in three five-story buildings will provide an additional 402 rooms meeting the target requirement for this area. Although the ideal configuration of BEQs is to consolidate each Battalion in approximate 400 room clusters to maintain unit integrity, this is not possible without the demolition of existing BEQs. At such time as the existing BEQs reach the limit of their lifecycle and maintenance and renovation are no longer viable, they may be replaced with comparable facilities to those proposed in the Facility Master Plan to achieve this objective.

Command Facilities

A new Headquarters Command Post (HQ CP) to meet the needs of the Regiment and Battalions is proposed along C Street. The HQ CP comprises three buildings. The one-story Regiment HQ CP is centrally located at southern end of the Battalion/Company HQ CP facilities. One building containing HQ CPs for two Battalions/Companies is proposed on each side of the Regiment HQ CP. Each two-story Battalion HQ CP can be designed to provide each Battalion with a prominent separate entrance. A central green space/plaza runs from the Regiment HQ CP between the Battalion/Company HQ CPs.

Maintenance Shops

Existing Motor Transport and Comm/Elec Maintenance Shops are maintained in the 100 Area. Space deficiencies in the existing facilities will require construction of new facilities or building additions where possible. An addition to the existing facilities between Cross and A Streets provides sufficient Motor Transport Shops for two Battalions. The existing Comm/Elec Shops provide sufficient space for three Battalions. A Motor Transport Maintenance Shop addition to the Comm/Elec Maintenance Shop will provide sufficient space for two Battalions. One new single-story Comm/Elec Maintenance Shop is proposed immediately south of the proposed new HQ CP on C Street. New single-story Regimental Motor Transport and Comm/Elec Maintenance Shops are proposed immediately north of the existing Comm/Elec Shops on Cross Street.

Supply/Storage Facilities

Supply/Storage facilities are provided outside of the Study Area.

Armory

The existing Armory facility located on A Street is inadequate to accommodate all of the requirements for one Regiment. An expansion to this facility is proposed to serve four Battalions. The recently constructed Armory (Building HP112) between the BEQs, and accessible from C Street, is proposed to serve the Regiment.

The preferred configuration is to provide all armory requirements for a complete Infantry Regiment in a single facility. One option to accommodate this configuration may be to further expand Building HP131 beyond what is proposed in the Master Plan. Although expansion would result in loss of existing surface parking associated with this facility, this option may be highly desirable since Building HP112 is targeted for the MP Company.

Indoor Simulated Marksmanship Trainer

The ISMT supporting the Infantry Regiment in this area will be incorporated in the 2D MAR DIV Training Center in Wallace Creek.

Mess Hall

A new single-story Mess Hall is proposed north of A Street.

Field Mess

A Regimental Field Mess facility is proposed in existing Building 123.

Medical/Dental Clinic

A new Medical/Dental Clinic is proposed in the existing location of Building 106 southwest of the intersection of McHugh Boulevard and A Street. This facility replaces the temporary dental facilities currently housed in trailers and will serve all Marines in the Hadnot Point area.

II Marine Expeditionary Force Training

The existing II MEF training facilities in Buildings 125, 126, and 127 will be relocated to a complex adjacent to the 2D MAR DIV Training Center at Wallace Creek. The existing facilities will be demolished to provide opportunities for future development beyond the Master Plan programming horizon.

POV Parking

Personally owned-vehicles (POV) parking areas have been relocated and in some cases enlarged through the demolition of existing obsolete facilities in order to achieve the 82 foot ATFP standoff required for buildings. Reconfigured surface parking facilities provide 2,522 POV parking spaces. Two additional three-deck parking garages have 500 spaces each, providing a total of 1,000 spaces. The parking goal

24 March 2012 based on the required facilities for this area is 3,726 spaces. The total number of spaces provided is 3,522 POV parking spaces.

Open Space/Conservation areas

Open spaces are provided surrounding the BEQ clusters. The land between Julian C. Smith Boulevard and the New River shoreline is preserved for open space and recreation facilities. The deficiency in parking may necessitate continued use of the existing parking areas within this strip of land.

Tables 4 and 5 list the existing facilities within the Hadnot Point areas 100 and 200 (sorted by stormwater sub-basins).

1.6. PUBLIC LANDS, SCENIC, RECREATIONAL, AND STATE NATURAL AREAS NEAR THE STUDY AREA

The Marine Corps permits public access to natural resources to the extent appropriate and consistent with the military mission and safety and security requirements. For the most part, the general public is allowed access to the base if accompanied by a Marine civilian staff or if they are participants in the sponsorship program associated with hunting, fishing and trapping. However, there are opportunities for the general public to participate in outdoor recreation aboard Camp Lejeune without accompaniment or sponsorship. The majority of these non-accompanied special events such as the Sand Jam, Maynia Carnival, and the 4th of July fireworks celebration are administered by the AC/S, MCCS.

The general public can also gain access to Camp Lejeune for bicycle road races and concerts, or for a self-guided cultural resources tour. MCCS also manages, coordinates and operates recreational activities such as the equestrian facilities, golf course, and developed campgrounds on Base.

Boat launching facilities for military personnel, civilian employees and guests are available at ten locations. These locations are Onslow Beach Bridge, Mile Hammock Bay, Sneads Ferry Bridge, Mill Creek, French Creek, Rhodes Point, Town Point, Weil Point, Maple Landing and Everett Creek Hunting, Fishing and Trapping Regulations3.

Onslow Beach is an 11-mile-long barrier island with the New River Inlet at its southern boundary and Bear Inlet at the northern boundary. The beach provides recreation and important habitat for nesting sea turtles, colonial nesting shorebirds, and the threatened seabeach amaranth.

The Hadnot Point Facility Master Plan (June 2009) addressed the need for maintaining open space and conservation areas through the implementation of the following measures:

New facilities adjacent to Wallace Creek or the New River will maintain a 50-foot buffer.

Recreation fields are proposed southeast of the intersection of the Cross Street extension and the proposed arterial road connecting Wallace Creek South facilities to Hadnot Point.

The land between Julian C. Smith Boulevard and the New River shoreline is preserved for open space and recreation facilities.

1.7. AREAS OF ARCHAEOLOGICAL OR HISTORICAL VALUE

A historic district has been designated between G and H Streets, within the Hadnot Point 300 Area (beyond the Study Area, which are Areas 100 and a section Area 200). Most 1940s-era buildings within the historic district are designated historic. The theater and training pool located west of McHugh Boulevard and between C and D Streets are also designated historic. Hadnot Point historic structures and associated historic district are delineated in Figure 2. All historic structures in the historic district will remain in place.

All new construction within the historic district must be compatible with the architectural style of the existing historic buildings and approved by the State Historic Preservation Office (SHPO) as demonstrating no adverse impact on district integrity. Demolition of historically-designated structures requires a greater level of SHPO review and mitigation of any adverse impacts through detailed photographic documentation.

1.8. WATER RESOURCES (SURFACE WATER AND GROUNDWATER)

1.8.1. Surface Waters: Sub-basin 03-05-02

The New River watershed (sub-basin 03-05-02) is the farthest west of the four major river systems in the White Oak River basin. It is also the largest and most populated and includes the City of Jacksonville and the Camp Lejeune Marine Corps Base. The New River is a coastal, tidal blackwater river with a watershed entirely within Onslow County. Gum-cypress swamps characterize the watershed above Jacksonville with upland areas used primarily for agriculture and forestry activities. At Jacksonville, the river widens into a broad, slow-moving tidal embayment. It eventually discharges to the Atlantic Ocean through a narrow opening called New River Inlet. There are 204 stream miles, 22,840 estuarine acres, and 15 miles of Atlantic coastline in this sub-basin. The White Oak River sub basin boundary is shown in Figure 7.

Camp Lejeune encompasses 16,650 acres of the New River and 1,720 acres of the Intracoastal Waterway. Approximately 17 miles of the river is found within the boundaries of Camp Lejeune.

Navigable creeks and waters adjacent to or within the boundaries of the Base (including the New River) are generally subject to the public trust rights of the State of North Carolina. Additionally, navigable waters in the New River watershed and the Intracoastal Waterway fall under the jurisdiction of the U.S. Army Corps of Engineers.

The Hadnot Point area is bordered on the west by the New River and to the north by Wallace Creek, which is defined by the state as inland public waters as shown in Figure . These two water bodies and their tributaries are subject to CAMA regulation. The estuary shoreline of the New River is within a 75-foot Area of Environmental Concern (AEC) permitting limited development subject to State review.

Wallace Creek, classified as inland public water, is subject to a 30-foot AEC.

Surface Water Classification and Impaired Waters

Section 3 summarizes the water quality classification(s), the NCDENR Use Support Rating and identifies specific water quality issues of the Hadnot Point area receiving streams.

Groundwater

Surficial Aquifer

The surficial aquifer is the uppermost aquifer in the groundwater system and confining units that comprise the hydrogeologic framework of the Coastal Plain of North Carolina. The surficial aquifer is unconfined and thus the water table is able to fluctuate with changes in ground water storage. It is the first aquifer to receive recharge, storing water as it moves laterally to rivers, lakes and other discharge areas, and downward in small quantities to deeper, confined aquifers. The rate at which recharge occurs in any given area in the study region is dependent on several factors, including:

Differences in precipitation rates from one area to another

Variations in soil types and their differing infiltration capacities

The position of the water table relative to land surface, which varies over time

The slope of the land surface

Evapo-transpiration rates which vary across the region and over time

The surficial aquifer is important because it extends over a large part of the Coastal Plain and the infiltration from rainfall is the bulk of the recharge to the Coastal Plain aquifer system. The aquifer transmits water laterally to streams and serves as a source bed holding the water that moves down gradient to deeper aquifers.

Recharge to the surficial aquifer depends on how rapidly rainfall can infiltrate into the aquifer. The rocks of the aquifer are not uniform in either composition or thickness. Recharge rates depend on the capacity of the soils formed from the various rock materials to allow water to move downward through the unsaturated zone.

One way of evaluating relative recharge rates is to look at the infiltration capacities of the various soil associations delineated by the U.S. Soil Conservation Service. Soil associations having similar characteristics of drainage, sand-clay content, and permeability were identified on the General Soil Map of North Carolina and arranged as groups having good, moderate, or poor infiltration capacity.

Soils deemed to have good infiltration capacity were well-drained to very well-drained sandy soil and sandy loam having vertical saturated permeabilities of 2 to 20 inches per hour. A few sandy soils containing significant amounts of clay were included if their permeabilities were within this range. The annual recharge to thick, sandy soils in the surficial aquifer is estimated to be as much as 20 inches of equivalent rainfall.

Fine sand, silty loam, and sand clay loam having vertical saturated permeabilities of 0.2 to 6 inches per hour were consider to have moderate infiltration capacity. Poorly drained clay, clay loam, and sandy-clay loam having vertical saturated permeabilities of 0.06 to 2 inches per hour were considered to have poor infiltration capacity. Recharge to the surficial aquifer through these soils having poor infiltration capacity may be as little as five inches per year. For the most part, soils derived from fine sand, silt, and clay of marine origin in the Tidewater region have poor to moderate infiltration capacities.

In the Study Area, results from the in-situ soil investigation (total of eight borings) indicate that the soil infiltration capacity at seven (7) boring sites ranges from 0.09 to 0.28 in/hour. The remaining site has an infiltration capacity of 2.99 inches/hour. The significant difference between the locations results from measuring a single fill modified site as compared to 7 original soils sites.

Castle Hayne Aquifer

The aquifer consists primarily of light gray to white moldic limestone and bryozoan rich limestone of the Eocene age Castle Hayne Formation, grading downward to calcareous, fine-grained sandstone in the deeper subsurface. It also contains the uppermost part of the Peedee Formation of Cretaceous age in central New Hanover County, the lower part of the River Bend Formation of Oligocene age in southern New Hanover County, and the upper part of the Beaufort Formation of Paleocene age in southeastern Brunswick County.

The aquifer is recharged by water moving downward from the surficial aquifer at a rate that varies from place to place. Rates of recharge are dependent on the thickness and vertical hydraulic conductivity of the overlying confining unit, and how much higher the water table elevation is above the elevation of the Castle Hayne potentiometric surface in recharge areas. The Castle Hayne aquifer is affected by seasonal recharge variations in a similar way as the surficial aquifer, indicating fairly quick recharge from the surficial to the Castle Hayne. Figure 8 illustrates a cross section of the Hadnot Point subsurface.

1.8.2. Presence of Hazardous Sites

Areas of concern include Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) designated areas for groundwater, aquifer, and soil contamination areas. These areas are under the control of the Camp Lejeune Installation Restoration (IR) program. One deep contamination plume identified within the Hadnot Point 100 Area previously contained a dry cleaning facility. This site is currently under assessment/remediation and only unoccupied structures (such as parking areas) are recommended for construction in this location.

1.9. FOREST RESOURCES

Camp Lejeune encompasses approximately 92,300 acres of forest, including 47,734 acres of pure pine, 21,985 acres of pure hardwood, and 22,596 acres of mixed pine/hardwood stands. An additional 17,328 acres are non-forested and 12,543 acres fall within impact areas.

Loblolly is the most common pine species, accounting for approximately 75 percent of timber on the Base. Blackgum is the most common hardwood. Fire plays a deciding role in the communities of Camp Lejeune, affecting canopy and understory density and species composition.

Forest resources in the Hadnot Point Area 100 include Bottomland hardwood forest, mixed pine and hardwood forest and pine forest. Area 200 forest resources include mixed pine and hardwood forest.

1.10. AQUATIC SPECIES AND THEIR HABITATS

1.10.1. Shellfish, fish, and their Habitats within the White Oak River Basin

Table lists the rare animals living in the aquatic habitats of the White Oak River Basin. Several of the listed rare aquatic species are entirely marine, such as Loggerhead and the Leatherback sea turtles.

Others live in the estuarine brackish waters between the ocean and freshwater streams and rivers. For example, the Carolina Diamondback Terrapin is a small to medium (4-9 inches long) reptile found in the coastal marshes, bays, lagoons, creeks, mud flats as well as tidal channels of sounds and estuaries that are bordered chiefly by Spartina. The American Alligator lives in slow moving coastal rivers, canals, lakes, marshes and estuaries and is a state and federally threatened species. The American Alligator has recovered from the low populations of the past century, and is no longer biologically threatened or endangered under the Endangered Species Act. However, it retains the federally threatened status due to its similarity of appearance to other rare crocodilians, and commercial hunting and trade are regulated.

1.11. WILDLIFE AND NATURAL VEGETATION IN CAMP LEJEUNE

Wildlife at Camp Lejeune is typical of that found in the southeastern Coastal Plain of North Carolina.

Wildlife species found year-round on MCBCL have been discussed in detail in the Integrated Natural Resources Management Plan6.

Mammals commonly found include white-tailed deer (Odocoileus virginianus), eastern gray squirrel (Sciurius carolinensis), eastern cottontail (Sylvilagus floridanus), opossum (Didelphis virginiana), southern flying squirrel (Glaucomys volans), and raccoon (Procyon lotor). Many reptiles and amphibians, from the pine wood snake (Rhadinaea flavilata) to the oak toad (Bufo quercicus), are abundant throughout the Base.

Birds common to the area include mourning dove (Zenaida macroura), northern bobwhite quail (Colinus virginianus), mockingbird (Mimus polyglottos), American robin (Turdus migratorius), catbird (Dumetella carolinensis), and various sparrows (Fringillidae) and warblers (Parulidae).

A multi-species scientific management strategy is used to maintain habitat requirements for several game and non-game species within MCB Camp Lejeune. Terrestrial game species include eastern wild turkey (Meleagris gallopavo), white-tailed deer, black bear, squirrel, bobwhite quail, eastern cottontail, and raccoon. Non-game species under management plans include the eastern bluebird (Sialia sialis), purple martin (Progne subis), least tern (Sterna antillarum), various neo-tropical migrant birds, and a variety of reptiles and amphibians (USMC, November 2001).

Virtually all birds that occupy MCBCL are…
