Please note that under the permit described, 0.9 acreS of wetland have already been filled. Under the new Nationwide permit rules, in general, impacts over 2 acres will rcquirean individual permit, inclusive of the area already filled. Therefore,. it. is considered highly likely that any activities that impact wetlands under the Master Plan will require an individual per:rnit rather than a Nationwide Permit. WETLAND REGULATIONS An Qverview of regulations affecting Unpacts to wetlands are provided below for your information. Local Regulations: Jefferson County To qualify as a .reglllated wetlanlJ in Jefferson County, an area must meet criteria defined inthe 1987 Army Corps of Engineers Manual(Corps of Engineers Wetlands Delineation Manual, Technical Report Y...87-1) Those criteria require that an area must predominantly support wetland vegetation, must have hydric soils, and must have wetlandbyclrology characteristics defined for the on site. soil type -- in this case, evidence or olJservation ofa long-duration water table at 12 inches or less depth. TheJDinimum regulatory wetland sizeinJeffers()n County is as follows: · No minimum size for Class I (highest quality) wetlands . 2500 square feet(50'x50') for Category II (high quality) wetlands 10,000 square feet (lOO'x1{lO') for Category III and IV (moderate quality, or smaIl, low quality) wetlands. . that means that an area that meets. the three-parameter criteria listed above must also be larger than the miniInum size to be regulated as a wetland by the County. The wetland edge is located. lJy evaluating the presence or absence of the three Parameters, then flagged inthe fieldJor a subsequent survey. Once identmedasjurisdictional wetland, the wetland is tlrated" using the 1991 edition of the Western Washington Wetlands Rating SysteIll, . The rating system combines a series ofquestions and a point system to determine the specific v~ue of the indiVidual wetland; Depending onsite specific, pre-development wetland vegetation, soils, hydrology and buffer characteristics, the Page 2 wetland haS greater or lesser value and so is afforded varying levels of protection in the form of wetland buffers. The higher the rating and the higher the intensity of development, the greater the buffer, ranging from a minimum of25 feet for low quality, small wetlands adjacent to low intensity development areas up to a maximum of 150 feet for the highest quality, or tare wetlands adjacent to high intensity development areas. The area within the wetland and buffers is generally considered unavailable for development, unless there is no reasonable alternative to the proposed activity. Federal Regulations: Army Corps of Engineers Any direct impacts to the wetiand are regulated by the Army Corps of Engineers (COE). The COE regulates wetlands of any size, i.e., there is no miniInum size for a fed,eral jurisdictional wetland. Furthermore, theCOE must be notIfied of impacts to wetlands, even if the mpacts are less than an acre in size. The COE sometimes chooses not to regulate impacts ofless than 1/3 acre, but prefer to make that decision themselves (i.e., if they arenotnotifie~, they may choose to check the project for potential violations once construction starts).. If they doreguiate impacts of less than 1/3 acre, it is usually under one of the many Nationwide Permits -'- pre-defined permits that describe certain allowed. actions and their related mitigations. Impacts of 1/3 t<r 2 acres must be reviewed and are typically regulated under one ofthe Nationwide J.>ermits. Impacts greater than 2 acres require an individual permit, that is, there is no pre..definedallowed impact. A detailed assessment of the project is required, including but not lirriited toan.alternatives analysis and detailed justification of the proposed impacts. Timing on the various levels of notification and permitting described above is varied. . But as a general rule, Nationwide Permits can take from one to several months; individual permits Can take from. one to several yeats. Other Regulatory Agencies Other potentially involved agencies include the Washington State Department ofFish and Wildlife (WDFW), and the Washington State Department of Natural Resources (DNR) Natural Heritage Program. \. DISCUSSION Site description The site is at JeffersonCountylnternational Airport, located about 3.5 miles southofl'ort Townsendwiththe majority of the inte11$ivelymanaged airport property lying between Highway 20 and Airport Cutoff Road -- a continuation of Beaver Valley Road. Please refer to the attached maps for details (Appendix IV). The site has been managed as an airport since the early 1900s. It was property of the Army during World War II, but reverted backto.localownershipafter the war. The airport site lies on a divide between two'drainagebasinswithapproxitnately the western Page 3 third of the propettyhistorically draining west and the eastern two-thirds drmningeast. Ditching and draining associated with the airport runways may have caused some of the water that historically drained west to drain east The eastern drainage forms the. headw~ters to Chimacum Creek. . The western drainage runs to Discovery.Bay via offsite wetlands and drainages. The site receives seasonal storm water drainage and some year-round substlfface seeping from. slopes to the north and, less so, from slopes to the south. So the divide isitselfinthebase of abroad flat swale. The current paved airport runway runs more or less east-west along the base oftheswale. l There is. an old abandoned graSs runway located about 200-350feetupslope fromthepaved runway. The areas adjacent to the paved runway areextensiyelyditched, including a central ditch, a southern ditch and a northern ditch running theentir~ length of the runway anddrainingtoabrrge detention pond atthe east end of the runway. . Thatpond drains under the Airport CutoffRQadto a second . large detention pond which. inturns drairlseasttoChimacUm Creek... .

There may be other surface and subsurface drainage structures that are not shown.. The purpose of this diagram is to show the majordrainagef?atures across_ the airport with special emphasis on those that might affect drainage in proposed constructiqn areas. Soils According to the JeffersonCounty soil survey, the follOwing soil series are mapped ollqrnearthe site: the Agnew silt loam, 0-8% slopes (classified asa fine-silty,mixed,m.esic Typic Qchra'lua1f); the Hoypus gravelly loamy sand, 0-15% sloPes (classified asa sandy-skeleta~ prixed,mesi5Typic Xerorthene); the San Juan gravelly sandy loam, 0-8% slopes (classified as coarse-loamY ().ver sandy or sandy skeletal, mixed, . mesic Pachic Xerumbrepe);and .the Swantowngravell~ san(iy loam and gravelly loam, 0-8% slopes (classified as a 10art1y-~keleta1, nuxed,mesic DystricEntic Fine-silty, mixed,' mesic Typic Ochtaqualt; gene.-aIlymeaning the soil haslffi atgillic(clay)horizon Iffid.gr~er thlm 35% base saturation (aU), is expected to have a sea~na1 high watertllble within 18inchesofthe soil surface {aqu),has a pale-colored, loW base saturation (less tl).1ffi 5Q%) surface horizon {ochr ),is otherWise typical (typic), has a lIlesictetnperature regime (mean annnal ten:lperatut:e ranges from ~o to 150 C (4 T .590 F), no specific mjneralogic source (mixed), and is greater than 18%c1ayand lessthlffi 15% sand (or coaiser) by weight (fine-$ilty), z .

The Swantown gravelly loam is mapped along the Hoypus toeslopein the north-central parts ofthe prQjectarea. The. Swantown gravelly sandy loam is mapped across the sWalebase in the western majority of the airport and in western portions of the project area. The San Juan gravelly sandy loam is mapped in the southeastern portions of the project area. The Agnew is mapped east of the project ar~a, along the toeslope adjacent to the Swantowngravelly.loam. Please refer to the attached soil map in Appendix IV for more details. for your information, standard characteristics of the mapped soil series are described in Appendix II. 'Please note that the SCS soil series maps and descriptions characterizeexvected characteristics in only the top 60-100 inches of soil. Furthermore, the map units can have rxtensive inclusions of other soil types, and in some fare cases" can he entirely in error. This particular Soil Survey is a lower level survey,' so should always be verified with fieldworJ.c.

Hydr910gy in several additional marginally wet areas was monitored to evaluate duration and depth of saturation. The data forms for each ofthe wetlands can be found in APPENDIX I. We provide a brief description of each system below to accompany the data Jorms. Wetland Al Thiswetlanclhas 9.4acresonsite, nut extendsoffsite to the west ,and north. Itsentire.acreage is unknOWIl' The wetland is located west of Highway20 atthe far \Vest end of the airport properties. . It is, a large Palustrine Emergent (PEM) wetland withscatt~redcommlll1iti~s of Palustrine Scrub-Shrub (PSS)( <30%) and some small openwater pockets (pOW). The wetland winds thtoughand around. a mosaic .of upland islands with much of the topographical variety a result ofold grading and filling.

Page 5 Rosa nutkana(N'utka rose). There. are alsosevel'al clumps ofPopulustremuloides (quaking aspen) andAlnus rubra (red alder) in the central portions' of the wetland. The drier PEM areas are dominated by grasses, the wetter areas by Juncus. effusus (soft rush) and occasional areas of Carex obnupta (slough sedge). The upland islands are dominated by grasses and Scot's broom. The source of hydrology is storm water runoff that collectsa(;ross the broad valley bottom, some ofwhiCl1 flows in through a culvettfrom east of Highway 20. This system drains northwest to off site wetlands, and eventually to Discovery Bay. The soils are mapped as Swan town . gravelly sandy loam, which in general is what we obs~rve., although with much higher water tables than is typical of the Swantownseries as desqribed in the soil survey. Wetland A2 This 5.3 acre wetland is 10cated'eastofHighway 20~t the west elld.ofthe airportrunwa)'. Similar to AI, it also is aJarge PEM wetland with scattered communitiesofPSS (<JO%) and '.somesmallopen water pockets. There is a ditch running up the middle .from the end of the runway that may drain both to the west and to the east. The predmninant western drainage crosses Highway 20 via a culvert. near the northwestentranc.e to drain to Wetland Ai,. so hydrologically, fotthe most part, it isth~same system as Wetland AI. The east~mdrainage is collected in the drains that run along the. runway to th~ east, eventually to. Chimacum Creek. . Tl1e PSS areas are dominated by Spirea douglasii (hardhack), willows.and black cottonwood saplipgs. The PEM areas are dominated by grasses,' Juncuse:ffUsqs (soft rush) and Carex obnupta (slollgh sedge). The upland edges are dominated by grasses and, Scot's broom. The source of hydrology isa. series of ditches along the runway as well as. seasonal doWnslope seepage from the north. As described above, this wetland drains mostly to the westtbrough a culvert under Highway 20,. then to Wetland At and eventually Discovery Bay. Some ofthe water also drains.tothe easttbrough the airport runway drainage system. As in AI, the soils are mapp~dasSwantO\vngravellysandylmun, which inigeneraliswhat we observe,. although with higherw~ter tablesthan istypic.al oftheSwantownseri~s.

There is a large fill area directly adjacent to the northeast, but it does not. appear to. have directly impacted the wetland, The PSS areas are dominated by Spir~a douglasii; the PEMareas by JQncus effusus.andC~exspecies. The upland edges are dominated by grasses and Scot's broom in cleared areas and Douglas-fir in the forested areas upslope. Page 6 The source of hydrology is toeslopecollection of stonnwater runoff . When enough watet collects, drainage overflows across the road to the south and intoWedand A2. The soils are mapped as Swantown gravelly sandy loam, which in general is observed, although with higher water tables than.is typical ofthe Swan town series, WetlandA4 This 11 acre wetland is located across a broad side slope at the northe,astend oftheairport. Its lower side slope areas form a large. Palustrine Emergent (PEM) wetland, dominate,d by grasses and Juncus.effusus.

The majority of the wetland groundwater water seeps into the. deeper sandy soils lower on the slope, but SOlIle r~ to the southeast to eventually drain d.irectlyinto the large drainage pond located at the eastendofthe runway. The soils are mapped as San Juan gravelly sandy loam -- a dark-colored, deep,' well-drained sandy soil.

Wetland AS TmsO.14 acre isolated wetland is located south of the runway in the southwest portions of the airport property in a .smallnatural drainage swale.. . The wetlan<lis a PEM system withjustafew blackcotton\Voodsaplings. It is very lipear,and seeps back into the ground before itge,tstill the way. downslope. The w~tlandvegetation isdoIIliru,tted by Juncuseffus;us; the upland with grasses. The sour.ce of hydrology is storm water runofIthatcollects ofitheshaUowClallmnsolls tothe south,. draining laterally tOWard the valley bottom. There.is no surface overflow, but grOundwater will eventually seep downslope. and be c.ollectedin the drainsysterns along the runway and flow to the east. The soils are mapped as Swan town gravelly sandyJoam or Clallmn. Bothofthose soils have a cemented 'substrate, which we observed. in the general area. But.in the wetland swalearea, the long. duration water table. is much highet.th&h is typical ofthe.Swantown series. Page 7 Wetland' A6 This 0.53 acre wetland is located at the toeslope across the nortlj. central part oftheairport properties. It is a stnall PEM/ PSS system associated with an old drain that runs drains west along the toeslope to divert some of the toeslope seep to the west rather than downslope toward the hangars and other airport buildings. The PEM areas .are grassed; thePSS areas are dOnUnated by Spirea douglasii, willows.andhawthome. The uplands to the south are grassed; the uplands to the north are forested. The source of hydrology is toeslopeco]Jectionofstormwaterrunoffthat collects across the broad side slopes above, The drainage ditch, -which extends beyond the end of the -wetland several hundred feet eventually drains to Wetland A2. The soils are mapped as Swantowh gravelly loam. We doobserveashallowsoil in this area, but the sand content is higher,. appearing to be in transition to the San Juan soils mapped farther east. Wetland A 7 This 0.14 acre wetlandislocatecl inthe far southeast comer of the airport, east pfthe Ai,rport Cutoff Road. It appears to be a remnant of wetlands that were probably more extensive inthis area before the large drainage facility about 50-100 feet to the north was installed. It is a . . PEM/PSSsystemdominated by Juncus effususand Spirea douglasii. The surrounding. uplands and buffers are dominated by grasses and Scot's broom. The source of hydrology is stonnwater runoff that collects from the adjacent road surface. The system appears to periodically surface flow into the dtainage facility that subsequently drains to ChimacumCreek. The soils we mapped asSan Juan gravelly sandy loam, which in general is observed<although with higher water tables than is typical of the San Juan series. Wetland AS This O.OS..acreisolated wetlandislocatedjust west of the Airport Cutoff Road, across the.road. from A7. It appears to be an old. compacted road surface where traffic rutted down to the underlying glacial till . It has stabilized and developed intoa'sm.aI1PE~dominatedbyJuncl1s efIususand' Carex obnuptawith occasional shrubby species, Theadjl;lcentuplands .are dominated by grasses and Scot'sbroom. . The source of hydrology is stormwater.runofffromthe adjacentfoadsurface'andpossibly some collectipnofstormwater runoff from the side slopes tothe south. There does not appear to be any surface drainage out of this system. The soilS are mapped as San Juan gravelly sandy. loam, but more resembles a poorly drained version of the Swantown soils. Page 8 Wetland A9 This O.lS .acte-wetland is located southwest of AS, ill an area that maY receive drainage fronl a recently c1e.arcutupslopearea, or may receive runofffrom old road surfaces to the West. It is a disturbed area that doesn't quite meet soils or hydrology criteria, but supports a healthy obligate and FACW wetland plantconnnunity, fucluding Typhalatifolia (cattails), Carex obnupta,and Spirea douglasii. The upland edges are dominated by grasses. The source of hydrology is storm water runoff that collects from upslope to the south and West. Surface overflow may collect in Wetland AS. T4e soils are mapped as San Juan gravelly sandy loam, but more resemble the Swan town with a shallow water table. . Wetland AlO ThisO.02acre isolatedwetlandis 10catedeastoftheAirport Cutoff Road, northeast of AS,fu an area that receives drainage from the adjacent road surface. . The surrounding area looks as if it was Once wetter, but has been drained to some degree. Thisrenmantwetland has deyeloped in a low-lying area that collects r.oadrunoff. Vegetationislimited, although the surrounding upland area supports a nice young stand of quaking aspen. The source of hydrology is road runoif. There is no apparent surfac.e outlet. The soils are mapped as San Juan gravelly sandy.1oam, which they resemble, but with a shallow water table. Wetland C 1 This 0.27 acre isolated wetland islocated in the uppercentralnotthernsideslopeofthe airport, directly north ofthe Spruce Qoose Restaurant. It is anisolated pocket of side slope seep entirely surrounded by dirt roads and parking area. Vegetation is grassy, but includesm.anyobligate sedges and rushes with a few small red alder saplings at the upslope edge. The source of hydrology is side slope seep and some roadruno~ There is noapparentsw1:ace outlet, although water drains down the slope and causes the. soils to saturate in the dirt parking and roads for about 10-15 feet around the southern edge. The soils are mapped as San Juan gravelly sandy loam, which they resemble, . but with a shallow water table. and much higher organic matter content. Wetland Classmcationand Rating For this prelitninary report, we.arenot providing any wetland rating .information, sfuce some of the information may change. after \Ve meet with the involved regulatory agencies. . Butfu. generaL Page 9 these systems will rate at least as Category III, and some will rate as Category II. None will meet requirements forratirig as Category I. In summary, the wetland described above drain awayfrom the center ofthe airport with some drainingto the west and some to the east. The western systems are more ext~nsive and continue off site to. the west. The eastern systems all appears to be more or less isolated, wit!). the exceptjon of Wetland A4 which actually drains directly into a large storm water facility at thee~st ~nd ofthe runway. The maj~rity of hydrology appearsto'come fromtoeslope seeps at the base of the broad slopes that run along the north side oHhe airport. That water drains out across the adjacent flats to either drain deeper into the sandy soils at the east end of the airport, or to surface above the shallow hardpans found at the western end of the airport. I hope' this report provides adequate information for you to proceed with project planning.

These soils are often associateq. with wetlands.. Generally, the upper' soils 'are. silt loams grading to silty clay loams WIth depth. Mottling is expected at 3 inches depth and gleying at 9 inches depth -- evidence of seasonal water almost to the surface for extended periods. Belowapptox. 30 inches (in the C horizon), gravel content increases abruptly from <5%' in thesurf{lC~ soilsto between 10 and 50% in the subsoils. The loweI' horizons are highly lamitiated and very hard g!acialtill. Average soil percolation rates in the upper 9 inches are expected t()be modemte (0.6-2 inches per hour), decreasing to moderately slow (0.2-0.6 inches per hour) below 9 inches depth. The Agnew soils are generally suitable for some crops and pasture with the mainlimitatioIl being seasonal wetness (a perched water table) at 12 to 24 inches depth. The main limita.tions for onsite septic and stomiwater treatment are related to both theminilllal depth to the hardpan and seasonal wetness. Soil water percolatingthtough these soilswilll11ove laterally in the. soilrather than down.. The. seasonal high water table and/or the sllallow till layer limits the amount of soil ava.ilable to effectively treatstormwater.orseptic effluent. HOYPUS SERIES The Hoypus gravelly loamy sands are deep, somewhatexcessivelydrain:dgtavellysoils formed in glacial outwash on terraces. They are usually found on llplands~slopesrangingfrom O..30~. The surface soils are generally dark gray to dark brown gravelly loamy sands. Subsoils are dark yellowish-brown gravellyJoamy sands overlying dark grayish brown gravelly loamy sands grading to very gravelly sands \\lith depth. The~e horizons with varying colors and textures are a result of different depositional events. Average soilpermeabilityis expected to be. rapid (6.-2() inches per hour). Most of the H9YPuS soils weI'eonginallywooded, bl,lt a great deal ofthell1appedacrea~ehas been<cleared andis now used for. li:mi...:t.ed p..asture, gardens, an... dhomesit. es...Thep. r. unary.'<.' . .li:mi..'tations are related to rapid percolation rates and slope. Storm water will percolate'intothe soilreadilym undisturbed areaS, but will receive relatiyelyIittle treatment inthe soil due to rapid percolation. Septic system q.esign will be limited also by rapid percolation, poor treatrnent ofeflluent, and steep slopes making design difficult. SAN JUAN SERIES The SanJuan gravellysandylo~areverydeep, .somewhat.excessively drainedsoilsfonued'in glacial outwash. The surface soils. are generallydari<-colored.gravelly.sandy 10aIllSo SoiItextl,lfe becomes coarser with depth, grading to gravelly 10arnY coarse sand and gravelly coarse sand. Page 1 Average soil permeability is expected to be rapid (6-20 inches per hour) throughout. The. San Juan soils are is used for fannland,hayland, pasture, woodland or homesites with few limitations. The priII1ary li1nitation for septic dfainfieldsor storinwater facilities are related to poor filtering <<apacity due to rapid percolation rates and relatively low surface area in sAndy soils. Ifhousing density is moderate to high, community sewage systems or alternative septic designs are recommended to reduce potential of water supply contamination by seepage. SWANTOWNSERlES The Swan town gravelly sandy lo~are' somewhat poorly-drained soils formed. in glacial till Ul}der a forest cover. Generally~there is.a very slowlyp~nneable.cementedtilllayer at l8~24 inches depth. The overlying soils are dark grayish brown to brown gravelly sandy 10aI11S with mottling from 5 inches do\Vn. It is often found on lowland seepltreas along toeslopes of hilly glaciaJ. terraces. Average' soil percolation rates in the upper horizons are expected to be moderately rapid (2-6 incht';sper hour) above the cemented layer and very slow (less than 0.06 in<.;hes per hout) in the cemented layer -"- effectively.impermeable. A perched water table is~xpectedat ~to 1 feet depth duting the rainy season. The Swantown soils are generally suitable for woodland, wildlife habitat and recreation. Septic systems are limited by the seasonal water table. Foundationsundet homes . are . expected to flood during the rainy season. Storm water systems don't work well due to minimal storage and treatment potential. Page 2 APPENDIX ill DEFINITIONS Column Headings: Horiz = horizon: This word refers to the horizontal bands of soil that form at various depths from the surface as a result of either accumulation of organic materials or leaching of clays and salts by water. '!A" horizons generally have an accumulation of organic materials. "B" horiwnsgenerally have an accumulation of clays or salts. "C" horizons are. generally either undifferentiated pareIlt material or are below the zone of major biological activity. A small letter followingtlie capital letter provides additional information. "Bw" describes a "cambic" or barely developed B horizon; A "ew", "es" Of' "ci" afteraBor Cdescnbes a horizon with weak cementation, strong cementation, and ind\lrationrespe()tively. An "r" after a Bor Cindicates that the horiwnis dominated by saprolyte, which is rotten rock- i.e. rockth.at is. so decomposed that it is ahnostsoil An '!R" after aC indicates tpat theC horizon is predominantly hard, ~decomposed bedrock. A "2" in front of a BorC horizon indicates that the subsoils have a different parent material than the overlying soils.

This project is shown on plans provided to the Corps of Engineers by kpff Consulting Engineers dated September 11, 1996. Department of the Army regulations dated November 22, 1991, authorize certain activities under nationwide permits, provided the enclosed conditions are met. Nationwide Permit 26 (Part 330, Appendix A) authorizes discharges of dredged or fill material into nontidal rivers, streams, and their lakes and impoundments, including adjacent wetlands, that are located above the headwaters where the average annual flow is less than 5 cubic feet per second. Your project is authorized by this nationwide permit. The entire text of Nationwide Permit 26 is enclosed. Prior to placing fill, you must contact the Washington State Department of Ecology to determine whether documented habitat for a state listed species is present. If present, this nationwide permit is not valid and you must contact us again to determine permit requirements. Please contact: State Nationwide Permit Coordinator Department of Ecology P.O. Box 47600 Olympia, WA 98504-7600 Telephone (360) 407-6917 ~ -2- This verification will be valid for a period of 2 years from the date of this letter or until the nationwide permit is modified, reissued, or revoked. This nationwide permit is scheduled to expire January 21, 1997, but is expected to be reissued. The verification will remain valid for the 2 years if reissuance of this nationwide permit is not modified or your proposed work complies with any subsequent modification. If in the future you propose to place additional fill in waters of the United States, including wetlands, on this site, you must contact us concerning any additional permit requirements. While you need no further authorization from us, you must still comply with other Federal, State, and local requirements which may pertain to the work. If you have any questions, please contact Mr. Jack Gossett at the above address or by telephone at (206) 764-6902. Sincerely, Robert H.

Miulli: On August 22, 1996, Mr. Paul Hamidi of my staff met with Ms. Lisa Palazzi of Pacific Rim Soil & Water to review various wetland regulatory issues with respect to the proposed developments at the Jefferson County International ~irport. The following points were discussed: 1) A drainage swale was created between the east end of the runway and SR 19 in 1989 or 1990. The work may have be$n done in wetlands, based on landscape position. However, there are no records indicating that the area was in fact a wetland. In any case, the U.S. Army Corps of Engineers (Corps) will not be taking ~llforce(n~nL actiou involving this work bcc~uoe a) excavation in wetlands did not become a regulated activity until Sept~mDer. 1993; b) the work was completed over five years ago ann is therefore beyond the statute of limitations for legal aFtions. 2) Ms. Palazzi indicated that ~ small area of wetl~nds adjacent to the access road off SR 20 (in the northwestl part of the airport) had been filled in 1992. No evidence of fill in wetlands was found in this area. ' 3) The wetland d~linenr.ion (p.nclns~d) for the proposed widening of the access road off. SR 20 was confirmed by Mr. Hamidi. The wetlands are considered to be "above the headwaters I' (definition enclosed) for the purposes of Nationwide Permit 26 (enclosed). Nationwide pennit 14 (enclosed) may also apply to the work if the trNotification" condition is met. 4} The site of the proposed tiedown apron expansion as depict.ed on the enclosed map was inspected for jurisdictional wetlands. No wetlands were found. A permit from the Corps will not be. needed for work in this area. f'lI-lU .l..i l'.J~L 1 'i ; 2U j l':Ul'1 u;, i 1 JI f-(i I ~l Jl mLlf<Y 1l1~IlNlH ( r II 'q ~! ,V]' , ).q'-jv.J,' .. , t.. . 1<:1.) 5) The site of the proposed taxiway anq eaxilanes as depieted on the enclosed map was inspected for jurisdictional wetlands. wetlands were found to exist on at least part of a linear flat at mid slope. It appears. this area was leveled in the pas~ and may have been an old runway. Although wetland hydrology cannot be confirmed at this time, hydric soills and .', hydrophytie vegetation are present.
