Individual Permit Application S&ME Project No. 1614-09-064 Stang County Airport Terminal Project August 18, 2009 BACKGROUND INFORMATION The Stanly County Airport (the Airport) is located at 38512 Aviation Drive approximately 4.5 miles southeast of New London and 1.5 miles west of Badin in Stanly County, North Carolina. The approximate location of the project area is depicted on the attached Site Vicinity Map (Figure 1 in Appendix II) and the 1993 New London, North Carolina United States Geological Service (USGS) Topographic Map (Figure 2 in Appendix II). The Airport is primarily a general aviation airport with flight training and limited passenger service operations. The North Carolina Air National Guard also operates from at this Airport. The Airport currently contains two runways which include Runway 4R-22L (5,500 feet long by 100 feet wide) and Runway 4L-22R (3,500 feet long and 75 feet wide). On November 24, 2004, the USACE issued a Nationwide Permit (NWP) 39 (USACE Action ID 200330686) for impacts to 0.29 acre of wetlands and 120 if of an intermittent stream at the Airport for the construction of two T-hangars located immediately adjacent to the proposed terminal site. A DWQ 401 Water Quality Certification (DWQ# 04-1808) was issued December 2, 2004. Mitigation for the impacts included payment into the NCEEP for wetland impacts only. Copies of the previous USACE and DWQ permits are included in Appendix III for your reference. The proposed terminal improvements will include impacts to 274 if to an intermittent stream and 0.09 acre of wetland. Per conversations with Mr. Steve Lund of the USACE and Mr. Alan Johnson of NCDWQ, the stream to be impacted is aquatically unimportant and will not require compensatory mitigation. Compensatory mitigation will be provided for the wetland impacts. NATURE OF ACTIVITY' The proposed project consists of the following improvements to the Airport: • Construction of a new two-story, 12,000 square foot (sf) terminal building and associated parking area. The new terminal will house an operations area, a customer waiting area, a pilot's lounge/quiet room, a large conference room to be used for various county meetings, Airport personnel office space, and future office space that is likely to be used by the county's economic development department in the future. Approximately 85 parking spaces, including four handicap spaces, are proposed. • A two-lane entrance road connecting the terminal and parking area to Airport Road. The entrance road will be approximately 570 if and includes embankment construction, grading, drainage, erosion and sediment control, and the culverting of an unnamed intermittent stream. • A two-lane connector road linking Aviation Drive and the rest of the airfield to the new terminal and parking area. The connector road will be approximately 430 1£ Individual Permit Application SWE Project No. 1614-09-064 Stanly County Airport Terminal Project August 18, 2009 PROJECT PURPOSE AND NEED The existing general aviation terminal building and parking area at the Airport were constructed in 1977 to serve a runway that began with a 3,900-foot length. In the last three decades, the runway has been lengthened to 5,5001f and strengthened to support multiple operations of large, military and civilian jet aircraft, which also necessitated the expansion of the BRL. As a result, the existing Airport terminal building and adjoining parking area are located within the existing BRL. See Figure 3 (Aerial Map - Existing Conditions) and Figure 4 (BRL Exhibit) in Appendix II for the location of the BRL. The BRL is defined as "A line which identifies suitable building area locations on airports." For civilian airports, it is described in FAA Advisory Circular 150/5300-13. According to FAA regulations, the BRL should include the runway protection zones, runway object free areas, runway visibility zones, navigational aid (NAVAID) critical areas, areas required for terminal instrument procedures, and an airport traffic control clear line of sight. A copy of the applicable portion of the Advisory Circular is included in Appendix IV. The existing terminal building is one-story, approximately 4,000 sf, and consists of an operations area, a small conference room, and airport personnel office space. The purpose of the project is to construct a new, larger terminal building and parking area that meets the needs of public demand and building codes, and also to comply with existing FAA guidelines regarding BRLs. The proposed improvements will be located outside the existing BRL and will enhance Airport safety measures. EXISTING PROJECT AREA CONDITIONS The project area is approximately 14 acres and is located east of the existing terminal building and two T-hangars on Airport property. The project area primarily consists of previously cleared, open land. The remainder of the project area consists of a small pine-hardwood area, two intermittent streams, and two small wetlands. Refer to Figure 3 (Aerial Map -Existing Conditions) in Appendix II for the approximate locations of these areas. Descriptions of these areas are provided below: Open Land The open areas appeared to be periodically maintained. Dominant species observed included blackberry (Rebus sp.), dog-fennel (Eupatorium capillifolium), green bristle grass (Setaria viridis), velvet witchgrass (Dichanthelium scoparium), Elliott's bluestem (Andropogon elliotti) and broomsedge (A. virginicus). Pine-Hardwood Wooded Area A pine-hardwood wooded area was observed on the eastern portion of the site adjacent to Airport Road. This area appeared to have recently (1 to 2 years ago) been thinned. Species observed included loblolly pine (Pinus taeda), Virginia pine (P. virginiana), white oak (Quercus alba), southern red oak (Q. falcata), sweetgum (Liquidambar styraciflua), eastern red cedar (Juniperus virginiana), and muscadine (Vitis rotundifolia). Individual Permit Application S&ME Project No. 1614-09-064 Stanly County Airport Terminal Project August 18, 2009 Streams Stream 1 is intermittent, flows roughly south to north, and is approximately two to three feet wide. Stream 1 originates on-site and is flanked by Wetland B as it exits the site to the northeast. Stream 2 is also intermittent and flows onto the site via a culvert underneath Airport Road. Stream 2, which is flanked by Wetland A, is approximately two to three feet wide. The riparian buffer surrounding these streams in minimal and consists mainly of saplings and blackberry. See the Stream Assessment Sheets in Appendix VI. Wetlands Wetlands A and B abut Streams I and 2. The dominant vegetation in the wetlands included red maple (Acer rubrum) and sweetgum saplings, Chinese privet (Ligustrum sinense), dogfennel, Japanese honeysuckle (Lonicera japonica), soft rush (Juncus effusus), and blackberry. Previous Jurisdictional Determination The on-site jurisdictional features were delineated by S&ME in April 2003 and a Notice of Jurisdictional Determination (USACE Action ID 200330686) was issued on May 14, 2003 (Appendix V). Corps biologist Amanda Jones signed the final wetland plat on November 24, 2004. Wetland and stream features in the project area are further described in Tables 1 and 2. PROPOSED IMPACTS TO JURISDICTIONAL WATERS The entrance road connecting the proposed tenninal and Airport Road will include installation of a culvert within Stream 1. The culvert and fill slopes associated with the proposed entrance road will impact approximately 179 If of Stream l and 0.079 acre of Wetland B. The proposed connector road linking Aviation Drive and the existing fuel farm to the new terminal will impact approximately 95 If of Stream 1 with fill slopes and a culvert. Stream impacts total approximately 274 If. Wetland impacts total approximately 0.09 acre. Construction of the proposed slopes to support the roads will require placement of approximately 20,000 cubic yards of clean, earthen. fill material. The proposed discharge (earthen fill, culvert) into the jurisdictional stream and wetland is necessary to facilitate construction of suitable, stable foundation for both roads. The fill material is to be discharged by industry-standard dump trucks, pans and bulldozers. Refer to the Site Plan (Figure 5), Profile View - Entrance Road (Figure 6),- and Profile View - Connector Road (Figure 7) in Appendix 11 for depictions of the proposed impacts.

In the absence of the proposed project, the site will remain vacant and will not be used to construct a new, larger terminal building needed to meet public demand and create additional space for Airport functions. The existing terminal will remain inside the BRL and not in compliance with existing FAA guidelines regarding BRLs. Alternative 1- Preferred Alternative The project will consist of two new roadways that will connect the proposed terminal building to Airport Road and to the rest of the airfield via Aviation Drive. Aircraft and vehicular safety concerns made it impossible to avoid the stream and wetlands completely. Airport staff will need to access the existing fuel farm from the new terminal building that does not require the vehicles to access the main road (Airport Road). Frequent trips will be made to the fuel farm and it would create a safety issue to enter into the main roadway each time. Additionally, the fuel trucks are not licensed to be on public roads. Alternative 1 would impact approximately 274 if of Stream 1, and approximately 0.09 acre of Wetland B. The roadways were laid out to minimize impacts to the existing wetland/stream areas as much as possible. The terminal entrance road was curved to reduce the impacts to the bulkier portion of the wetlands. Both roadways attempt to intersect the wetlands/stream areas as close to perpendicular as possible. The roads tie-in slopes have been designed to be as steep as site conditions will allow and still achieve vegetative growth (thus minimizing the stream impacts). A bottomless culvert was considered for the impacted area along the entrance road, but proved to be too expensive for this project. Alternative 2 Alternative 2 involves the same layout for the terminal, parking lot and connector road, but includes construction of a straight entrance road connecting Airport Road and the proposed terminal. Alternative 2 impacts approximately 312 if of Stream 1, approximately 601f of Stream 2, and 0.052 acre of Wetlands A and B. Alternative 2 was not selected because of the additional linear footage (372 if vs. 274 1f in Alternative 1) that would be impacted. Table 4: Proposed Impacts To On-site Wetlands Individual Permit Application S&ME Project No. 1614-09-064 Stanly County Airport Terminal Project August 18, 2009 COMPENSATORY MITIGATION 1. Mitigation Banks There were no known private mitigation banks with the requested credit type located in the hydrologic unit where the proposed impacts will take place. 2. In-Lieu Fee Programs To offset the unavoidable loss of jurisdictional stream, the applicant intends to satisfy mitigation requirements by payment of funds into the NCEEP. Per conversations with the USACE and NCDWQ, the impacted stream is aquatically unimportant and will not require compensatory mitigation. Compensatory mitigation will be provided for the wetland impacts. A letter from the NCEEP (March 12, 2009) indicating they are willing to accept payment for impacts associated with the proposed project is included in Appendix V. PROTECTED SPECIES One federally protected (endangered) species, Schweinitz's sunflower (Helianthus schweinitzii), is currently listed in Stanly County. On March 2, 2009, scoping letters were sent to the U.S. Fish and Wildlife Service (USFWS) and the North Carolina Natural Heritage Program (NCNHP). The NCNHP was aware of an existing Schweinitz's sunflower location in the area (approximately one mile south of site). The NCNHP recommended a survey for Schweinitz's sunflower be conducted in the appropriate season (late August-October) to determine if this specie was present or would be impacted by the proposed project. A copy of the NCNHP letter is attached in Appendix V. At the time this permit was submitted, a response from the USFWS had yet to be received. In 2004, S&ME conducted a Protected Species Assessment of the site as part of the previous NWP for the T-hangar project, and determined that, based on the literature and pedestrian field review, the open land and woodland margins on the site may provide suitable habitat for the Schweinitz's sunflower. The field review did not reveal the presence of federally listed protected species on the site. It was our opinion that the proposed development of the project area is not likely to impact listed protected species at the time. A copy of the Protected Species Assessment is included in Appendix V. HISTORICAL/CULTURAL RESOURCES A scoping letter was sent to the North Carolina Department of Cultural Resources - State Historic Preservation Office (SHPO) in 2004 for the same site of the proposed activities. The SHPO issued a letter (September 28, 2004) indicating they were "aware of no historic resources which would be affected by the project."

Impact Justification and Mitigation 1. Avoidance and Minimization 1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. Aircraft and vehicular safety concerns as well as the position of the wetland/stream in the landscape made it impossible to avoid the stream and wetlands completely. In an effort to minimize impacts, the roadways were laid out to minimize impacts to the existing wetland/stream areas as much as possible. The terminal entrance road was slightly curved to reduce the impacts to the bulkier portion of the wetlands. Both roadways attempt to intersect the wetlands/stream areas as close to perpendicular as possible. The roads tie-in slopes have been designed to be as steep as site conditions will allow and still achieve vegetative growth (thus minimizing the stream impacts). A bottomless culvert was considered for the impacted area along the entrance road, but proved to be too expensive for this project. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. See above. Also, proper sediment and erosion control BMPs will be implemented during and after construction. 2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State 2a.

Buffer mitigation requested (DWQ only): square feet 4e. Riparian wetland mitigation requested: 0.25 acres 4f. Non-riparian wetland mitigation requested: acres 4g. Coastal (tidal) wetland mitigation requested: acres 4h. Comments: On November 24, 2004, the USACE issued a Nationwide Permit (NWP) 39 (USACE Action ID 200330686) for impacts to 0.29 acre of wetlands for the construction of two T-hangars located immediately adjacent to the proposed terminal site. A DWQ 401 Water Quality Certification (DWQ# 04-1808) was issued December 2, 2004. Mitigation for the impacts included payment into the NCEEP for wetland impacts. The proposed terminal improvements will include impacts to 0.09 acre of wetland. No mitigation required for stream impacts per Corps and DWQ due to intermittent/aquatically unimportant status. 5.

After reviewing your application, we have determined that this project is covered by Water Quality General Certification Number 3402, which can be viewed on our web site at http://h2o.enr.state.nc.uslncwetlands. The General Certification allows you to use Nationwide Permit Number 39 once it is issued to you by the U.S. Army Corps of Engineers. Please note that you should get any other federal, state or local permits before proceeding with your project, including those required by (but not limited to) Sediment and Erosion Control, Non-Discharge, and Water Supply Watershed regulations. The above noted Certification will expire when the associated 404 permit expires unless otherwise specified in the General Certification. This approval is only valid for the purpose and design that you described in your application. If you change your project, you must notify us in writing, and you may be required to send us a new application for a new certification. If the property is sold, the new owner must be given a copy of the Certification and approval letter, and is thereby responsible for complying with all conditions. In addition to the requirements of the certification, you must also comply with the following conditions: 1. Deed notifications or similar mechanisms shall be placed on all remaining jurisdictional wetlands and waters or areas within 50 feet of all streams and ponds on the property. These mechanisms shall be put in place within 30 days of the date of this letter or the issuance of the 4D4 Permit (whichever is later). A sample deed notification format can be downloaded from the 401NVetiands Unit web site at httr)://h2o. enr. state. nc. us/ncwetiands. 2. The Mooresville Regional office shall be notified in writing once construction of the project has begun. 3.

RUNWAY TO PARALLEL TAXIWAY AM TAXILANE SEPARATTON. a. Standards. Tables 2.1 and 2-2 present the runway centerline to parallel taxiway/taxilane centerline separation standard. This distance is such to satisfy the requirement that no part of an aircraft (tail tip, wing tip) on taxiway/taxilane centerline is within the runway safety area or penetrates the obstacle free tone (OFZ). The computer program cited in appendix 11 may be used to determine the increase to these separation distances for elevation. b. Recommendations. To have room for the acute-angled exit taxiway, provide a runway centerline to parallel taxiway centerline of at least 400 feet (120 m) for Airplane Design Groups I and 11, 500 feet (150 m) for Airplane Design Group 111, and 600 feet (180 m) for Airplane Design Groups IV, V, and VI. 210. BUILDING RESTRICTION LINE (BRL). A BRL should be placed on an airport layout plan for identifying suitable building area locations on airports. The BRL should encompass the runway protection zones, the runway object free area, the runway visibility zone (see paragraph 503), NAVAID critical areas, areas required for terminal instrument procedures, and airport traffic control tower clear line of sight. 211. OBJECT CLEARING CRITERIA. Safe and efficient operations at an airport require that certain areas on and near the airport be clear of objects or restricted to objects with a certain function, composition, andlor height. The object clearing criteria subdivides the 14 CFR Part 77, Subpart C, airspace and the object free area (OFA) ground area by type of objects tolerated within each subdivision. Aircraft are controlled by the aircraft operating rules and not by this criteria. a. Standards. Object clearance requirements are as follows: (1) Object Free Area (OFA). Object free areas require clearing of objects as specified in paragraph 307, Runway Object Free Area, and paragraph 404, Taxiway and Taxilane Object Free Area (OFA). 2/14197 (2) Runway and Taxiway safety Areas. Runway and taxiway safety areas require clearing of objects, except for objects that need to be located in the runway or taxiway safety area because of their function. Objects higher than 3 inches (7.6 cm) above grade should be constructed on low impact resistant supports (frangible mounted structures) of the lowest practical height with the frangible point no higher than 3 inches (7.6 cm) above grade. Other objects, such as manholes, should be constructed at grade. In no case should their height exceed 3 inches (7.6 cm) above grade. Underground fuel storage facilities should not be located within runway and taxiway safety areas (see AC 150/5230-4), Aircraft Fuel Storage, Handling, and Dispensing on Airports). Tables 3-1, 3-2, 3-3, and 4-1 specify runway and taxiway safety area standard dimensions. (3) Obstacle Free ne (OFZ). Obstacle Free Zones require clearing of object penetrations, except for frangible visual NAVAIDs that need to be located in the OFZ because of their function. Paragraph 306 specifies OFZ standard dimensions. (4) Threshold. The threshold obstacle clearance surfaces, defined in Appendix 2, paragraph 5, require clearing of object penetrations. (5) NAVAIDsI Certain areas require clearing for the establishment and operation of NAVAIDs. These NAVAID critical areas are depicted in chapter 6. (6) 14 CFR Pan 77 Obstructions to Air Navgation- Obstructions to air navigation must be removed unless an FAA aeronautical study, based on proposed operations, determined otherwise. To determine otherwise, the FAA must find no substantial adverse effect as defined in Order 7400.2, Procedures for Handling Airspace Matters, Chapter 7, Evaluating Aeronautical Effect, Section 1, General. The FAA, normally, limits aeronautical studies of existing objects to obstructions to air navigation which are not included in the criteria cited in paragraphs 211a(1) through (5). (7) Runway Protection Zone (RPZ). The RPZ requires cleating of incompatible objects and activities as specified in paragraphs 212a(1)(a) and 212a(2). (8) General. Other objects which require clearing are those which generally can have an adverse effect on the airport. These include objects in the irmer part of the approach area (coinciding with the RPZ) such as fuel handling and storage facilities, stroke and dust generating activities, misleading lights, and those which may create glare or attract wildlife. 12 Chap 2 06/19/2008 b. Recommendations. Other objects that are desirable to clear, if practicable, are objects that do not have a substantial adverse effect on the airport but, if removed, will enhance operations. These include objects in the controlled activity area and obstructions to air navigation that are not covered in paragraph 21 La, especially those penetrating an approach surface. On a paved runway, the approach surface starts 200 feet (61 in) beyond the area usable for takeoff or landing, whichever is more demanding. On an unpaved runway, the approach surface starts at the end of the area usable for takeoff or landing. 212. RUNWAY PROTECTION ZONE (RPZ). The RPZ's function is to enhance die protection of people and property on the ground. This is achieved through airport owner control over RPZs. Such control includes clearing RPZ areas (and maintaining them clear) of incompatible objects and activities. Control is preferably exercised through the acquisition of sufficient property interest in the RPZ. a. Standards. (1) RPZ ConfigurationA"ation. The RPZ is trapezoidal in shape and centered about the extended runway centerline. The central portion and controlled activity area the two components of the RPZ (see Figure 2-3). The RPZ dimension for a particular runway end is a function of the type of aircraft and approach visibility minimum associated with that runway end. Table 2-4 provides standard dimensions for RPZs. Other than with a special application of declared distances, the RPZ begins 200 feet (60 m) beyond the end of the area usable for takeoff or landing. With a special application of declared distances, see Appendix 14, separate approach and departure RPZs are required for each runway end. (a) The Central Portion of the RPZ. The central portion of the RPZ extends from the beginning to the end of the RPZ, centered on the runway centerline. Its width is equal to the width of the runway OFA (see Figure 2-3). Paragraph 307 contains the dimensional standards for the OFA. (b) The Controller) Activity Area. The controlled activity area is the portion of the RPZ to the sides of the central portion of the RPZ. (2) Land Use. In addition to the criteria specified in paragraph 211, the following land use criteria apply within the RPZ: AC 150/5300-13 CHG 13 (a) While it is desirable to clear all objects from the RPZ, some uses are permitted, provided they do not attract wildlife (see paragraph 202.g., W ddlife Hazards, and Appendix 17 for dimensional standards), are outside of the Runway OFA, and do not interfere with navigational aids. Automobile parking facilities, although discouraged, may be penmitted, provided the parking facilities and any associated appurtenances, in addition to meeting all of the preceding conditions, are located outside of the central portion of the RPZ. Fuel storage facilities may not be located in the RPZ. (b) Land uses prohibited from the RPZ are residences and places of public assembly. (Churches, schools, hospitals, office buildings, shopping centers, and other uses with similar concentrations of persons typify places of public assembly.) Fuel storage facilities may not be located in the RPZ. b. Recommendations. Where it is determined to be impracticable for the airport owner to acquire and plan the land uses within the entire RPZ, the RPZ land use standards have recommendation status for that portion of the RPZ not controlled by the airport owner, c. FAA Studies of Objects and Activities in the Vicinity of Airports. The FAA policy is to protect the public investment in the national airport system. To implement this policy, the FAA studies existing and proposed objects and activities, both off and on public-use airports, with respect to their effect upon the safe and efficient use of the airports and safety of persons and property on the ground. These objects need not be obstructions to air navigation, as defined in 14 CFR Part 77. As the result of a study, the FAA may issue an advisory recommendation in opposition to the presence of any off airport object or activity in the vicinity of a public- use airport that conflicts with an airport planning or design standard or recommendation. 213. RUNWAY HOLDING POSITION (HOLDLINE). At airports with operating airport traffic control towers, runway holding positions (holdlines) identify the location on a taxiway where a pilot is to stop when he/she does not have clearance to proceed onto the runway. At airports without operating control towers, these holdlines identify the location where a pilot should assure there is adequate separation with other aircraft before proceeding onto the runway. The holdline standards, which assume a perpendicular distance from a runway centerline to an intersecting taxiway centerline, are in Tables 2-1 and 2-2. However, these distance standards may need to be longer and placed in such a way to take into account the largest aircraft (tail, body, or wing tip) expected to use the runway from penetrating the Obstacle Free Zone. 214. to 299.

No. 1614-09-064 Dear Mr. Daves: Dee Freeman Secretary I have examined the Natural Heritage Program records for this site as indicated on the map you sent. We have no records from the site itself. However, we have a record for smooth sunflower (Helianthus laevigatus) very near the site. It occurs on the road side about 0.1 mile to the south. We also have a record for the federally listed Schweinitz's sunflower (Helianthus schweinitzii) about 1 mile south of the site. Because smooth sunflower often co-occurs with Schweinitz's sunflower, and either can occur in open habitat, including forest edges and road sides, there appears to be high potential for either species to occur on the site. A careful survey in the appropriate season is needed to determine if these species are present and would be affected by the project. . / Sincerely, Michael P.

(S&ME) is pleased to submit this report detailing our Protected Species Assessment for the above-referenced site located west of Badin in Stanly County; North Carolina (Figure 1). This work was performed in accordance with S&ME Proposal No. 1614-3791-04, dated November 1, 2004. This report and the on-site pedestrian survey have been conducted to assess the potential for the presence of protected species at the Albemarle-Stanly County Airport in preparation for proposed additions on the site. The 19.9-acre site (35° 24.68'N/80° 8.95W) is located west of and adjacent to Airport Road (SR 1949) and is owned by the Stanly County Airport Authority (Stanly County Tax Parcel No. 665002767703). The site is identified on a portion of the New London, N.C. USGS 7.5-minute topographic quadrangle map, dated 1993 (Figure 2). Proposed plans for the project area include the construction of two airplane hangars, a stormwater pond, and associated aprons. The area of impact of the proposed project is located on the western portion of the site. SBJJiE, Inc.

The area of impact consists of undeveloped, open land and a small portion of woodland, which includes 0.29 acres of jurisdictional wetlands and 120 linear feet of intermittent stream channel. The properties adjacent to the site consist of woodland, a fuel farm and associated airport buildings. The undeveloped portions of the site primarily consist of two habitat types: open land and mixed hardwood woodland. Two intermittent stream channels and jurisdictional wetlands are located within the wooded area. Refer to the Site Aerial Map (Figure 3) for the locations of various habitats and stream features. Open Land A majority of the site consists of open land. The herbaceous layer covers approximately 90 percent of the ground. Dominant herbaceous species observed included broomsedge (Andropogon elliottii), foxtail grass (Setaria geniculata), purpletop (Tridens favus), panic grass (Panicum spp.), dandelion (Taraxacum officinale), doll's daisy (Erigeron spp.), rabbitfoot clover (Trifolium repens), red clover (T. pratense), wild strawberry (Fragaria virginica), cinquefoil (Potentilla canadensis), thistle (Cirsium horridulum), vetch (Vicia spp.), Indian hemp (Apocynum cannabinum), wood sorrel (Oxalis Florida) and horse-nettle (Solanum carolinense). Portions of the open land appear to be maintained by periodic mowing. Vegetation surrounding the jurisdictional wetlands near the fringes of the open land included beggar ticks (Bidens spp.), dock (Rumex spp.), sundrops (Oenothera spp.), sericea lespedeza (Lespedeza cuneata), soft rush (Juncus eFfusus), needlepod rush (Juncus scirpoides), umbrella sedge (Cyperus strigosus) and smartweed (Polygonum pensylvanicum). Ironweed (Vernonia noveboracensis), elderberry (Sambucus canadensis), pokeweed (Phytolacca americana), cottonwood (Populus deltoides), red maple (Ater rubrum) and Chinese privet (Ligustrum sinense) were also observed in this area. 2 Protected Species Assessment S&MF Project No. 1614-04-340A Albemarle-Stanly County Airport T-Hangar Project _ November 2, 2004 Mixed Hardwood Woodland Mixed hardwood woodland areas are located on the eastern, central and northern portions of the site. Within the wooded areas, linear wetlands flanking two intermittent streams are present. The canopy within the mixed hardwood woodland has a closure ranging from approximately 70 to 80 percent at heights ranging from approximately 70 to 90 feet. Dominant canopy species include tulip-tree (Liriodendron tulipifera), white oak (Quercus alba), willow oak (Q. phellos), red maple, American sycamore (Platanus occidentalis) and sweetgum (Liquidambar styraciflua). The subcanopy has a closure of approximately 20 percent at a height ranging from approximately 10 to 25 feet. Individuals of the canopy dominants as well as flowering dogwood (Cornus florida) and winged elm (Ulmus alata) comprise the subcanopy. The under-story shrub and woody vine layer within the mixed hardwood community has coverage of approximately 10 to 20 percent. Dominant shrub and woody vine species include saplings of the canopy and subcanopy dominants, as well as Japanese honeysuckle (Lonicera japonica), bamboo grass (Microstegium vimineum), grecnbriar (Smilax rotundifolia) and blackberry (Rubus spp.). The herbaceous layer is minimal and covers less than five percent of the ground. The longer of the two intermittent streams originates within the thin, wooded area on the central portion of the site and flows east, northeast. Another intermittent stream flows underneath Airport Road and joins the other stream. The channels are shallow and less than three feet wide. Channel bed substrate consisted of loamy silts and silty foams. No standing or flowing water was observed in the two intermittent streams during the pedestrian survey. Various mosses and Christmas fern (Polystichum acrostichoides) were observed near the dry streams. 3 Protected Species Assessment S&ME Project No. 1614-04-340A Albemarle-Stan] County Airport T-Han ar Project_ November 2 2004 2.0 PROTECTED SPECIES The North Carolina Natural Heritage Program (NCNHP) database was consulted regarding current federal and state listed species within Stanly County. Listed species and their respective federal and state status are identified in Table 1. Explanations of Federal and State rankings are included at the end of the table. The NCNHP database identified the following federal and state listed species in the vicinity of the site: TABLE 1: PROTECTED FLORA & FAUNA SUMMARY ALBEMARLE-STANLY COUNTY AIRPORT T-HANGAR PROJECT Species State Status Federal Status Brief Habitat Description Creeper T Mixed substrates (silt, sand, gravel) of Strophitus undulatus streams, rivers and lakes Carolina fatmucket T Streams with a substrate of pebbles or large Lampsihs radiata conspicua rocks Carolina creeksheli E FSC Silty sand or clay along small streams of Villosa vaughaniana the Pee Dee & Catawba River basins Bald eagle T T (PD) Mature forests or cliffs near larger bodies Haliaeetus leucocephalus of water Prairie blue wild indigo Glades, woodland borders and open forest Baptisia minor var. aberrans located over basic soils Georgia aster Symphyotrichum georgianum T C Open woods and roadsides Schweinitz's sunflower P E Open woods and roadsides with Helianthw schweinitzii Mecklenburg/Iredell/Enon/Poindexter soils Wright's cliff-brake Pellaea wrightiana E-SC -- Rock outcrops with seepage areas Yadkin River goldenrod Solidago plumosa E FSC Riverside banks of the Yadkin River - ?.•.6 ., i - i nrcatcneu C, -A anmdate FSC - Fedcral Species of Concern SC - Special Concern PD - Proposed De-listed The NCNHP records identified the presence of known occurrences of the Carolina creekshell, bald eagle and Schweinitz's sunflower within the New London, North Carolina USGS Quadrangle. A pedestrian field review was performed for the federal and state listed species in suitable habitats within the site on November 2, 2004. Chris Daves and Catherine McRae of S&ME performed the field review. Descriptions of the species listed above, and the results of the pedestrian field review are included in the following sections of this report. 4 Protected Species Assessment S&ME Project No. 1614-04-340A Albemarle-Stanly County Airport T-Hanaar_Proicet November 2, 2004 Creeper -- State Listed Threatened BIOLOGICAL OPINION: NO EFFECT The creeper is a freshwater mussel usually characterized by a smooth, shiny, yellowish to .dark brown periostracurn (outer covering of shell). Shells tend to be thin and fragile. Green rays of the periostracum may extend the entire surface of the shell. Its nacre (interior shell) is iridescent with colors ranging from gray to blue to salmon. The habitat of the creeper consists of a variety of substrates including silt, sand, and gravel within headwater streams, large rivers, or lakes to a depth of four meters. The species has been reported in the Bear Creek subbasin, which encompasses the western portion of Stanly County, including the city of Albemarle. The on-site intennittent channels do not appear to provide suitable habitat for the creeper. These streams did not contain water at the time of our field review. No known occurrences of the creeper have been documented in the immediate area of the airport. No mussel species were observed during the pedestrian survey. Accordingly, future development of the site is not expected to impact this species. Carolina fatmucket - State Listed Threatened BIOLOGICAL OPINION: NO EFFECT The Carolina fatmucket is a mussel that generally inhabits streams with a substrate of pebbles or large rocks, although a few populations have been documented in lakes. The oval-shaped shell is reddish-brown and is covered with dark greenish-black streaks. There are two elongated and slightly bowed lateral teeth found on the left valve and one on the right valve. Each valve has two triangular tooth-like structures along the hinge of the shell. This mussel has been reported in Stanly County with a documented population in Lake Tillery, which is located several miles southeast of the proposed project. The on-site intermittent channels do not appear to provide suitable habitat for the Carolina fatmucket. These streams did not contain water at the time of our field review. No known occurrences of the Carolina fatmucket have been documented in the immediate area of the airport. No mussel species were observed during the pedestrian survey. Accordingly, future development of the site is not expected to impact this species. Carolina creekshell -- Federal Species of Concern State Listed Endangered BIOLOGICAL OPINION: NO EFFECT The Carolina creekshell is a freshwater mussel usually characterized by a golden-brown shell. Rays of the periostracurn are generally complete, narrow and green in color. Its marsupium (egg pouch) is ivory-colored and its nacre is bluish white or white. The habitat of the Carolina creekshell consists of silty sand or clay along small stream banks. In areas of abundance, the species has been found occupying substrates of mixed sand and gravel. The species has been reported in the Long, Big Bear, Stony, Mountain, and Little Mountain creeks within Stanly County. 5 Protected Species Assessment S&ME Project No. 1614-04-340A Albemarle-Stanly Count Airport T-Man ar Project November 2 2004 Although known occurrences of the Carolina creekshell have been reported in Little Mountain Creek located north of the site. the on-site intermittent channels do not appear to provide suitable habitat for the Carolina creekshell. These streams did not contain water at the time of our field review. No mussel species were observed during the pedestrian survey. Accordingly, future development of the site is not expected to impact this species. Bald eagle - Federall Listed Threatened State Listed Threatened BIOLOGICAL OPINION: NO EFFECT This large raptor has characteristic adult plumage consisting of a white head and tail with a dark brown body. Juvenile eagles are completely dark brown and do not fully develop the majestic white head and tail until the fifth or sixth year. Fish are the primary food source, but bald eagles will also take a variety of birds, mammals, and turtles (both live and as carrion) when fish are not readily available. Adults average about three feet from head to tail, weigh approximately 10 to 12 pounds and have a wingspread that can reach seven feet. Generally, female bald eagles are somewhat larger than the males. The typical nest is constructed of large sticks and is lined with soft materials such as pine needles and grasses. The nests are very large, measuring up to six feet across and weighing hundreds of pounds. Nesting and feeding sites are generally in the vicinity of large bodies of open water. The site does not contain suitable habitat for the bald eagle. There are no large open waters on the site. Badin Lake, the closest large body of open water, is over a mile north of the site. No active or abandoned bald eagle nest sites were observed as a result of the pedestrian field review. Accordingly, future development of the site is not expected to impact this species. Prairie blue wild indigo - State Listed Threatened BIOLOGICAL OPINION: NO EFFECT The prairie blue wild indigo is a rhizomatous, perennial herb with obovate to lanceolate, three- foliated leaves. It usually grows to a height of 1.5 to 3 feet. Flowers are blue or violet and bloom in April and May. Legumes are usually thin-walled, brittle and firm with 3 to 6 cm long bodies. The habitat of the prairie blue wild indigo includes glades, woodland borders and open forest located over basic soils. The site does not provide suitable habitat for prairie blue wild indigo. No open forests or glades were located on the site. No individuals of this species were identified during the pedestrian survey. Accordingly, future development of the site is not expected to impact this species. 6 Protected Species Assessment S&ME Project No. 1614-04-340A Albemarle-Stanly County Airport T-Hangar Project November 2, 2004 Georgia aster - State Listed Threatened BIOLOGICAL OPINION: NO EFFECT Georgia aster is a perennial herb in the aster family that generally grows up to 1 meter in height. The leaves are gradually reduced proceeding upwards along the stem. The ray flowers are purple while the disk flowers are white, turning darker with age. The flowers are approximately 7 cm in diameter. The plant flowers during the month of October. Typical habitat associated with Georgia aster includes areas with regular moderate disturbance such as open woods, cedar barrens, roadsides, and power line rights-of-way. The preferred sites are characterized by abundant sunlight and little competition in the herbaceous layer. The site contains areas that may provide suitable habitat for the Georgia aster. Dry upland and open land are abundant on the site. No known occurrences of this species have been documented in the immediate area of the airport. Additionally, this species is listed as a historic record for Stanly County, indicating that it has not been observed in the county in at least 20 years. Accordingly, future development of the site is not expected to impact this species. Schweinitz s sunflower - Federally Listed Endan ered State Listed Endano-ere d BIOLOGICAL OPINION: NO EFFECT Schweinitz's sunflower is a perennial herb in the aster family that generally grows up to 1.5 meters in height. This plant has tuberous roots, with each stem attached to a single tuberous root. The stems are scabrous and generally reddish in color. The leaves are sob pubescent below and scabrous on the upper surface. The ray flowers are yellow, while the disk flowers are purplish. Schweinitz's sunflower blooms during the month of September. The habitat of Schweinitz's sunflower is open woods, roadsides, and power line rights-of-way, often on basic soils with bare spots or a gravel component. The preferred sites are characterized by abundant sunlight and little competition in the herbaceous layer. The site contains possible suitable habitat for Schweinitz's sunflower. Woodland margins and open land are abundant on the site. No known occurrences of this species have been documented in the immediate area of the airport and no individuals of Schweinitz's sunflower were observed during field review. Accordingly, future development of the site is not expected to impact this species. 7 Protected Species Assessment S&ME Project No. 1614-04-340A Albemarle-Stanly County Airport T-Hangar Proiect November 2, 2004 Wri rht's cliff-brake - State Listed Endangered BIOLOGICAL OPINION: NO EFFECT This plant is characterized by rhizome scales with pale brown margins and a dark median stripe. Fronds are bipinnately compound. Each leaflet has a slightly wavy margin that is rolled under toward the center. Spores are uniform in size and shape. The North Carolina population of this species is disjunct from the typical southwestern United States locale. Habitat for Wright's cliff- brake includes rock outcrops that are either exposed or partially shaded. The rock outcrops usually contain nutrient-rich seepage. The site does not provide suitable habitat for Wright's cliff brake. No rock outcrops were identified within the site boundaries. No individuals of this species were identified during the pedestrian survey. Accordingly, future development of the site is not expected to impact this species. Yadkin River Qoldenrod -1 ederallXS 2ecies of Concern State Listed Endan ered BIOLOGICAL OPINION: NO EFFECT This perennial, rhizomatous herb was thought to be extinct after the construction of two dams on the Yadkin River until a small population was discovered in 1994. Leaves are alternate and flowers are bright yellow with blooming usually occurring in the fall. Habitat for Yadkin River goldenrod includes the rocky riverbanks of the Yadkin River. The site does not contain suitable habitat for the Yadkin River goldenrod. The only known population of this species is located on Yadkin River, several miles north of the site. No individuals of this species were identified during the pedestrian field review. Accordingly, future development of the site is not expected to impact this species. In addition to these protected species, the NCNHP identified a population of the smooth sunflower (Helianthus laevigatus), located directly across Airport Road from the proposed project. Smooth sunflower is classified by the NCNHP as a significantly rare plant that is at the periphery of its range in North Carolina. During field review, the known population was located directly across Airport Road from the site. Additionally, approximately 20 individuals of smooth sunflower (Photo 6) were identified within the subject site. These plants were located along a wooded border in the eastern portion of the property (Figure 3). At this time, no development plans are proposed for this portion of the property and accordingly, these plants are not anticipated to be impacted by the proposed development. 8 Protected Species Assessment S&ME Project No. 1614-04-340A Albemarle-Stanly County Airport T-Han ar Project November 2, 2004 3.0 METHODOLOGY S&ME reviewed the NCNHP database for records of protected species known to occur within Stanly County, N.C. The purpose of the search was to identify current and historic documented occurrences of protected species located within this county. Additionally, S&ME personnel reviewed available supporting information including the New London, N.C. USGS Topographic Quadrangle, and applicable soil survey sheets. The purpose of reviewing this supporting information was to identify drainage features and soil types in the study area. During field reconnaissance, S&ME personnel integrated the information obtained from this supporting documentation with field evaluation for the presence of protected species or potential protected species habitat. Portions of the study area that matched descriptions of preferred habitat for protected species listed in Table I were considered to be potential habitat for the respective protected species. These areas were subsequently field reviewed more intensively to confirm the presence/absence of the respective species. 4.0 SUMMARY AND CONCLUSIONS Based on the literature review, habitat assessment, and pedestrian field review of the site, it is our opinion that the site does not provide suitable habitat for most of the listed protected species with documented populations in Stanly County. Open land and woodland margins on the site may provide suitable habitat for the Georgia aster and Schweinitr's sunflower. The pedestrian field review did not reveal the presence of federally or state listed protected species on the site. It is our opinion that the proposed development of the project area is not likely to impact listed protected species. No further study of the site is recommended at this time. 9 Protected Species Assessment S&ME Project No. 1614-04-340A Albemarle-Stanly County Airport T-Han ar Proie ct November 2 2004 S&ME appreciates the opportunity to be of service to you by performing this threatened and endangered species assessment for the site.

North Carolina GeoTechnologies Project No. 1-08-0388-EA Gentlemen: 3200 Wellington Court, Suite 108 Raleigh, North Carolina 27615 Phone 919-954-1514 Fax 919-954-1428 www.geotechpa.com GeoTechnologies, Inc. has completed the authorized investigation to evaluate subsurface soil conditions for the new terminal building at Albemarle-Stanly County Airport located in New London, North Carolina. Subsurface conditions at the site were investigated by completing fourteen soil test borings at the approximate locations shown on the attached Figure IA and Figure 1B site plans. Table I?lists the North Carolina State Plane coordinates of each boring. The boring locations were established in the field using a hand-held Trimble GPS unit, and therefore the indicated locations should be considered accurate to within 10 feet. The test borings were extended to termination depths ranging from approximately 6.5 to 14.5 feet below site grade utilizing standard penetration test procedures at selected intervals to evaluate the consistency and density of the subsurface soils. This report presents the findings of our investigation and our recommendations concerning site grading and foundation support. SITE AND PROJECT INFORMATION It is our understanding that a partially cleared area adjacent to the existing apron and t- hangars, east of the current terminal building, is under consideration for development with a new two?storv terminal building. Parking areas will be located to the southeast of the new terminal building. At the time this report was issued, GeoTechnologies had not been provided with any structural loading details or final grades. However, based on our past experience with similar facilities, we anticipate that column loads will not exceed 100 kips, and that wall loads will not exceed 3 to 4 klf. It is our understanding that the entire site will be raised to some degree, with the shallowest fill depths in the building area and the deepest fill depths in the roadways. Geotechnicol and Construction Materials Testing Services Talbert & Bright, Inc. Albemarle-Stanly County Airport-New Terminal August 6, 2003 Page: 2 SUBSURFACE CONDITIONS Generalized subsurface profiles prepared from the test boring data are attached to this report as Figure 2A and 2B to graphically illustrate subsurface conditions encountered at this site. More detailed descriptions of the conditions encountered at the individual test boring locations are then presented on the attached test boring records. Topsoil extended no deeper than a few inches in any of the test borings. Soils near the surface consisted of low plasticity silty clays, clayey silts and sands with Unified Soil Classifications of CL-ML and SC-SM. These soils extend to depths of up to 7 feet, and exhibited penetration resistances in the range of 10 blows per foot (bpf) to more than 30 bpf. Fill soil consisting of clayey silt with gravel was encountered in boring B-5 to 7 feet. Penetration resistances within this soil were 9 and 47 bpf. Partially weathered rock (PWR) was encountered at depths as shallow as a few inches in some borings, and all borings encountered PWR at depths of no more than about 7 feet. PWR is defined as material which could be penetrated with the soil drilling augers but which exhibited penetration resistances in excess of 100 bpf. All the test borings were terminated in PWR at depths in the range of 6.5 to 14.7 feet. Borings B- 1. B-2, B-4, B-6, B-8, and B-12 reached auger refusal at depths ranging from 6.5 to 12.5 feet. No groundwater was encountered in any of the borings, however, the site is conducive to the development of perched groundwater during periods of wet weather. RECOMMENDATIONS The following recommendations are made based upon a review of the attached test boring data, our understanding of the proposed construction, and past experience with similar projects and subsurface conditions. Once specific development details become available, that information should be provided to GeoTechnologies so that our recommendations can be confirmed, extended, or modified as necessary. Additionally, should subsurface conditions adverse to those indicated by this report be encountered during construction, those differences should be reported to us for review and comment. Site Grading Considerations. Site grading should initially begin with the removal of any surface vegetation from within the limits of the new construction. Following removal of these materials. GeoTechnologies recommends that all areas at grade or designated to receive fill be proofrolled with a loaded tandem axle dump truck in the presence of a geotechnical engineer to identify areas which require repair. Special attention should be given to areas with old fill (B-5). These areas should be evaluated with proofrolling and with hand auger borings to verify that they are consistent with our test boring results. Final grades are not known to us, however, it appears that the entire site will need to be raised. Fill depths are expected to be shallow at the new terminal building, near the apron, and to increase in depth away from the apron with the deepest areas of till in the driveways. WNW Talbert & Bright, Inc. Albemarle-Stanly County Airport - New Terminal AUL,Ust 6. 2008 Page: 3 The on-site materials, excluding vegetation, should be suitable for reuse as structural fill provided compaction moisture can be maintained near optimum. The contractor should be prepared to moisture condition (wet or dry) the soils as necessary in order to achieve adequate compaction. Any rock till should be used in nonstructural areas or in deeper pavement fills unless it is first run through a crusher. No rock particle sizes of greater than 6 inches may be used in building pad areas. Off-site borrow should consist of clayey or silty sands or low plasticity silts and clays having a Unified Soil Classification of SC, SM, ML, or CL. Fill soils should be compacted to not less than 95% of the standard Proctor maximum dry density, except in the final foot for building pads, where this requirement should be increased to 98% of the standard Proctor maximum, and in the final 8 inches for roadways and parking areas, where this requirement should be increased to 100% of the standard Proctor maximum. Subgrade in structural areas should be proofrolled with a loaded tandem axle dump truck prior to placement of aggregate base. Foundation Support Considerations. The results of the test borings indicate that subsurface conditions on the site are suitable for use of shallow spread footing foundations assuming that site grading is performed as previously outlined. The foundations may be designed for a maximum allowable bearing pressure of 4,000 psf for foundations bearing on approved soils. Foundations should bear at a minimum of 18 inches below grade for frost protection. If foundations are excavated to PWR, an allowable bearing pressure of 10,000 psf may be used. The foundations should bear on properly compacted fill materials, or on approved virgin soils. GeoTechnologies recommends that all foundation excavations be evaluated by a geotechnical engineer to verify that suitable bearing materials have been encountered. This inspection should include verifying that the bearing soils are not highly plastic. In the event that the bearing soils are observed to be unstable, those areas should be repaired as directed by the on-site engineer. For the assumed maximum structural loadings, we estimate that total settlements will be on the order of 1 inch or less. Figure 3 shows expected settlements versus different assumed column loads up to 200 kips. This figure assumes that grade in the building will not be raised by more than 4 feet as settlements will increase with increasing fill thickness. Approved residual soils or compacted structural fill will provide adequate support for conventional concrete slab-on-grades. We recommend that slab-on-grades be designed for an assumed Subgrade modulus of 100 pci. If stone is used below the slab-on-grades, we recommend using CABC base course stone rather than clean washed stone in order to provide better protection for the subgrade until concrete can be placed. Difficult Excavation Considerations. One of the most significant findings of our investigation is the presence of very shallow difficult excavation materials, including in proposed borrow areas. As indicated by the attached test boring data, the subsurface profile includes partially weathered rock beginning at depths as shallow as a few inches in some areas. Our experience has been that PWR exhibiting resistances of 50 blows per 2 inches of penetration and softer can generally be preloosened with a D-8 dozer drawing a single tooth ripper during general site grading. Material harder than 50 blows per 2 inches of penetration generally requires blasting to remove with Talbert & Bright, Inc. Albemarle-Stanly County Airport - New Terminal AULyust 6. 2008 Pa'e: 4 conventional equipment. The attached Figure 4A and Figure 4B show the depths at which PWR was encountered at each of the test boring locations, while Figure 4C and Figure 4D indicate those areas where PWR which exhibited penetration resistances of 50 blows per 2 inches of penetration or harder was encountered or where auger refusal was met. The equipment utilized for installation of utilities and foundations is less powerful than that which is used in general excavation and our experience has been that excavation of PWR harder than 50 blows per 4 inches of penetration is typically impossible with most equipment available for trench excavation, such as track mounted backhoes equivalent to a CAT 320 or 330. Large track mounted backhoes with rock teeth can sometimes excavate PWR with penetration resistances ranging from 50 blows per 4 inches to 50 blows per 6 inches of penetration; however, the rate of excavation is slow and most contractors will request a trench rock price for any removal of PWR. Therefore, it is recommended that trench excavation depths be kept at a minimum in order to reduce the amount of difficult excavation material which will be encountered. Additionally, consideration should be given to using a common utility trench corridor if possible and preripping the corridor with a D-8 dozer if possible during general site grading, or blasting if necessary. Contractors have also been successful in the past utilizing a Vermeer rock saw to install small diameter utilities where they must extend into PWR. We suggest that if grades will not be raised in the building that consideration be given to preripping and preblasting below the maximum utility or foundation depth to facilitate their installation. If blasting is used to loosen PWR, special care must be taken to not overblast, and to remove all loose rock after blasting, especially in structural areas. All material blasted or ripped must be replaced with compacted fill. Pavement Design Considerations. No detailed information regarding traffic volumes was available at the time of this investigation. If you will provide us with an estimate of traffic volumes and loadings, we will be happy to prepare a detailed pavement design. Lab tests have indicated that a design CBR value on the order of 1 to 1.5% is representative of the fine-grained soils found on-site. If present below pavement subgrades these soils will require a heaver than normal pavement section and may require either chemical stabilization or removal and replacement to at least 12 inches below the soil subgrade. If a significant area of the pavement subgrade is impacted by these soils, consideration should be given to using lime/cement stabilization to improve subgrade support (instead of mass undercut). Plan grades will dictate the amount of these soils exposed, and this will help to determine if any repair is necessary, and if necessary which approach will be most cost effective. Since it is anticipated that the parking lot and roadway areas will be raised, we recommend that granular borrow material be stockpiled if possible to be used as till in at least the top foot of the parking lot and roadway areas. Properly conditioned, these soils will exhibit CBR values on the order of 7%. Alternatively, an off site granular source Could be identified. The silty soils found around boring B-13 should be avoided for use in the top foot of subgrade below pavement structures. Y Talbert & Bright, Inc. Albemarle-Stanly County Airport - New Terminal August 6, 2008 Page: 5 The most important factors affecting pavement life in the area of the site are the condition of the subgrade immediately prior to base course stone placement and post construction drainage. We recommend that the subgrade of all pavement areas be proofrolled and that any yielding areas be identified and repaired prior to placement of the base coarse stone. All subgrade soils should be compacted to a minimum of 100% of the standard Proctor maximum dry density immediately prior to base course stone placement where appropriate. We recommend that all pavement areas be properly graded to promote run-off of water and to prevent ponding of water on the pavement surface which can lead to eventual saturation of subgrade soils and the loss of pavement support. Permanent drainage swales and/or french drains should be installed on the uphill side of pavement areas to intercept and divert water. Strip drains should be provided within traffic islands to prevent stone and subgrade saturation. Seismic Design Considerations. Based on the results of the soil test borings and our past experience in the area, we recommend utilizing a soil site classification of "C" with respect to soil seismic design considerations.

Vernon Subject: FW: Stanly Terminal Chad, I have converted the standard permeability measurement of cm/sec to inch/ hour below. The soils at the site should be in the range of 1 E-05 cm/sec. 1 E-05 0.01417 inches per hour Chad, The soils in the terminal area consist primarily of slightly clayey fine sandy silts. These soils will typically produce a permeability of about 1E-05 to 1E-06. I would not expect the permeability to be less than 1E-06. I would note that rock is fairly shallow across the site, typically within 6 feet of the surface and this will impact the infiltration of water into the soils by creating a perched water condition above the rock layer. 1101MR41 GeotechnicaI and Construction Materials Testing Services David R.
