PROJECT DESCRIPTION - The purpose of this plan is to identify measures to be implemented during construction of a multiuse path and land grading associated with this project. Impervious runoff will be directed into the existing amenity pond and channeled into a water quality detention/retention pond sized for treatment. There is no off -site drainage or previously existing impervious. The site is located south of US Highway 17 between Mallory Creek and Wire Road within Phase 5 of the Brunswick Forest community. The developable site is gently rolling and wooded and is bordered to the North and East by wetlands and to the West and South by the Brunswick Forest and future and existing residential areas.

Hanover Design Services 1123 Floral Pkwy. Wilmington, NC 28403 Brunswick Forest Phase 5A — SHWT determination POND No. 32 Field visit: 8-25-10 References: Soils at the pond site are mapped as Leon and Baymeade Series fine sands (USDA NRCS National Cooperative Soil Survey map and Official Series Description attached), well drained soils with rapid to poor permeability and relatively flat slopes of 0-8%, abutting the delineated wetlands soils which are mapped as predominantly Muckalee Series foams, poorly drained with moderately poor permeability and flat slopes. Observations: One soil boring was observed as follows (location map attached): The seasonal high water table is normally evident by observation of redoximorphic features suggesting past conditions of saturation and reduction, indicated by colors of chroma 2 or less (Munsell) at greater than 2% of soil volume in mottles or a distinct horizon subdivision. There was evidence of redoximorphic features at about 2'-4" (2.37') in the bore with a distinct chroma and evidence of wetness at that depth (the first 3" at the test site was vegetation and root mat, not soil). This observation was in line with the expected depth to seasonal high water in the soil profile of 18" to 36" for Leon Series soils. Elevation read at the boring for Pond 32 was 19.92 MSL, resulting in a SHWT elevation of 17.6 MSL (19.92 — 2.37 = 17.55). Summary: Observed indications of SHWT depth were in line with predicted values. Pond No.32 SHWT = 17.6 MSL. •°" 'CAX. Q. •.JJ e� SEAL 2GG0� s . 8829-shwt-32.doc 8\2Co•tc�> David S.

In addition, Talquin soils have a spodic horizon less than 6 inches in thickness and the somewhat poorly drained Witherbee soils have less than 0.06 organic carbon in the upper 12 inches of the spodic horizon. GEOGRAPHIC SETTING: Leon soils are on upland flats, depressions, stream terraces and tidal marshes of the lower Atlantic and Gulf Coastal Plain. They formed in thick beds of acid sandy marine sediments. The climate is humid subtropical. Slopes range from 0 to 5 percent. The average annual temperature ranges from 66 to 70 degrees F., and the average annual precipitation ranges from 61 to 69 inches at the sample location. GEOGRAPHICALLY ASSOCIATED SOILS: These include the Chipley, Foxworth, Hurricane, Kershaw, Lakeland, Lynn Haven, Mascotte, Olustee, Ortega, Osier, Plummer, Portsmouth, Pottsburg, Ridgeland, Scranton, and Wesconnett series. Chipley, Foxworth, Kershaw, Lakeland, and Ortega soils are on higher positions and lack spodic horizons. In addition, Chipley soils are somewhat poorly drained, Foxworth soils are moderately well drained to excessively drained, Kershaw and Lakeland soils are excessively drained, and Ortega soils are moderately well drained. Hurricane and Pottsburg soils have a spodic horizon at depths greater than 50 inches. In addition, Hurricane soils are somewhat poorly drained and on higher positions and Pottsburg soils are somewhat poorly to poorly drained and on similar to slightly higher positions. Lynn Haven soils are on similar positions but have an umbric epipedon. Mascotte and Olustee soils are on similar positions but are underlain by argillic horizons under the Bh horizon. Osier soils, are on flood plains and lack spodic horizons. Plummer soils are on similar to lower positions and are grossarenic. The very poorly drained Portsmouth is on lower positions and lack spodic horizons. Ridgeland and Wesconnett soils and lack E horizons between the A and Bh horizons. In addition, Ridgeland soils are on slightly higher positions and are somewhat poorly drained while Wesconnett soils are in lower depressional areas and are very poorly drained. The poorly drained Scranton soils are on similar to slighter higher positions and lack spodic horizons. DRAINAGE AND PERMEABILITY: Poorly drained and very poorly drained; moderate to moderately rapid permeability in the Bh horizons, moderate to moderately slow permeability in the Bh horizons, and rapidly permeable in the other layers. USE AND VEGETATION: Most areas of Leon soils are used for forestry, rangeland and pasture. Areas with adequate water control are used for cropland and vegetables. The natural vegetation consists of longleaf pine, slash pine, water oak, myrtle, with a thick undergrowth of sawpalmetto, running oak, fetterbush and other lyionia, inkberry (gallberry), chalky bluestem, creeping bluestem and pincland threeawn (wiregrass). In depressions, the vegetation is dominated by brackenfern, smooth sumac and swamp cyrilla are common. Vegetation in the tidal marshes includes bushy seaoxeye, marshhay cordgrass, seashore saltgrass, batis, and smooth cordgrass.

PROJECT DESCRIPTION - The purpose of this plan is to identify measures to be implemented during construction of a multiuse path and land grading associated with this project. Impervious runoff will be directed into the existing amenity pond and channeled into a water quality detention/retention pond sized for treatment. There is no off -site drainage or previously existing impervious. The site is located south of US Highway 17 between Mallory Creek and Wire Road within Phase 5 of the Brunswick Forest community. The developable site is gently rolling and wooded and is bordered to the North and East by wetlands and to the West and South by the Brunswick Forest and future and existing residential areas.

Hanover Design Services 1123 Floral Pkwy. Wilmington, NC 28403 Brunswick Forest Phase 5A — SHWT determination POND No. 32 Field visit: 8-25-10 References: Soils at the pond site are mapped as Leon and Baymeade Series fine sands (USDA NRCS National Cooperative Soil Survey map and Official Series Description attached), well drained soils with rapid to poor permeability and relatively flat slopes of 0-8%, abutting the delineated wetlands soils which are mapped as predominantly Muckalee Series loams, poorly drained with moderately poor permeability and flat slopes. Observations: One soil boring was observed as follows (location map attached): The seasonal high water table is normally evidentby observation of redoximorphic features suggesting past conditions of saturation and reduction, indicated by colors of chroma 2 or less (Munsell) at greater than 2% of soil volume in mottles or a distinct horizon subdivision. There was evidence of redoximorphic features at about 2'-4" (2.37') in the bore with a distinct chroma and evidence of wetness at that depth (the first 3" at the test site was vegetation and root mat, not soil). This observation was in line with the expected depth to seasonal high water in the soil profile of 18" to 36" for Leon Series soils. Elevation read at the boring for Pond 32 was 19.92 MSL, resulting in a SHWT elevation of 17.6 MSL (19.92 — 2.37 = 17.55). Summary: Observed indications of SHWT depth were in line with predicted values. Pond No.32 SHWT = 17.6 MSL. \\ay\�etuye..,aew ,••'rat, GARt7i/*^ `' SEAL 20007 ; may.

Texture is sand or fine sand. COMPETING SERIES: The Tal uin and Witherbee series are the only known series in the same family. They are on similar to slightly higher positions. In addition, Talquin soils have a spodic horizon less than 6 inches in thickness and the somewhat poorly drained Witherbee soils have less than 0.06 organic carbon in the upper 12 inches of the spodic horizon. GEOGRAPHIC SETTING: Leon soils are on upland flats, depressions, stream terraces and tidal marshes of the lower Atlantic and Gulf Coastal Plain. They formed in thick beds of acid sandy marine sediments. The climate is humid subtropical. Slopes range from 0 to 5 percent. The average annual temperature ranges from 66 to 70 degrees F., and the average annual precipitation ranges from 61 to 69 inches at the sample location. GEOGRAPHICALLY ASSOCIATED SOILS: These include the Chipley, Foxworth, Hurricane, Kershaw, Lakeland, Lynn Haven, Mascotte, Olustee, Ortega, Osier, Plummer, Portsmouth, Pottsbm'e, Ridgeland, Scranton, and Wesconnett series. Chipley, Foxworth, Kershaw, Lakeland, and Ortega soils are on higher positions and lack spodic horizons. In addition, Chipley soils are somewhat poorly drained, Foxworth soils are moderately well drained to excessively drained, Kershaw and Lakeland soils are excessively drained, and Ortega soils are moderately well drained. Hurricane and Pottsburg soils have a spodic horizon at depths greater than 50 inches. In addition, Hurricane soils are somewhat poorly drained and on higher positions and Pottsburg soils are somewhat poorly to poorly drained and on similar to slightly higher positions. Lynn Haven soils are on similar positions but have an umbric epipedon. Mascotte and Olustee soils are on similar positions but are underlain by argillic horizons under the Bh horizon. Osier soils are on flood plains and lack spodic horizons. Plummer soils are on similar to lower positions and are grossarenic. The very poorly drained Portsmouth is on lower positions and lack spodic horizons. Ridgeland and Wesconnett soils and lack E horizons between the A and Bh horizons. In addition, Ridgeland soils are on slightly higher positions and are somewhat poorly drained while Wesconnett soils are in lower depressional areas and are very poorly drained. The poorly drained Scranton soils are on similar to slighter higher positions and lack spodic horizons. DRAINAGE AND PERMEABILITY: Poorly drained and very poorly drained; moderate to moderately rapid permeability in the Bh horizons, moderate to moderately slow permeability in the Bh horizons, and rapidly permeable in the other layers. USE AND VEGETATION: Most areas of Leon soils are used for forestry, rangeland and pasture. Areas with adequate water control are used for cropland and vegetables. The natural vegetation consists of longleaf pine, slash pine, water oak, myrtle, with a thick undergrowth of sawpalmetto, running oak, fetterbush and other lyionia, inkberry (gallberry), chalky bluestem, creeping bluestem and pineland threeawn (wiregrass). In depressions, the vegetation is dominated by brackenfern, smooth sumac and swamp cyrilla are common. Vegetation in the tidal marshes includes bushy seaoxeye, marshhay cordgrass, seashore saltgrass, batis, and smooth cordgrass. DISTRIBUTION AND EXTENT: The Atlantic and Gulf Coastal Plain from Mississippi, Alabama, Florida, Georgia, South Carolina, North Carolina, Virginia and Maryland. The series is of large extent.

Texture of the A horizon is sand, fine sand, loamy sand, or loamy fine sand. The E horizon has hue of IOYR or 2.5Y, value of 4 to 8, and chroma of I to 6 or is neutral with value of 6 to 8. Texture is sand, fine sand, loamy sand, or loamy fine sand. The Bh portion of E/Bh horizon or Bh horizon, where present, is granular to massive with hue of 5YR to IOYR, value of 3 to 7, and chroma of 2to8. The E' horizon, where present has hues of 7.5YR to 2.5Y, values of 4 to 8, and chroma of 2 to 6 or it is neutral with values of 6 to 8. It is sand, fine sand, loamy sand or loamy fine sand. The Bt horizon has hue of 7.5YR to 2.5Y, value of 5 to 7, and chroma of 4 to 8. Mottles are in shades of yellow, brown, or gray at depths below 25 inches in some pedons. A gray matrix may be present in the lower Bt horizons of some pedons. Texture is commonly sandy loam or fine sandy loam but some pedons are sandy clay loam. The lower Bt horizon may occur as lamella of sandy loam. The BC horizon has hue of 7.5YR to 2.5Y, value of 5 to 7, and chroma of 2 to 8. Mottles are in shades of yellow, brown, or gray in some pedons. Texture is loamy sand, loamy fine sand, sandy loam, fine sandy loam or in some pedons sandy clay loam. The C horizon has hue of 7.5YR to 2.5Y, value of 5 to 8, and chroma of 1 to 8 or is mottled in shades of these colors. Texture is sand or fine sand or stratified. sandy, loamy, or clayey material. Some pedons have thin discontinuous Bh bodies in the C horizon. COMPETING SERIES: Ailey, Blaney, Chipola, Chisolm, Coosaw, Garcon, Gomer , Kenansville, Remlik, Tenaha, Tomahawk, Uchee, and Valhalla in the same family. Closely related soils are the ALM, Eustis, Kureb, Onslow, Seagate, Wagram, and Wakulla series. All of these soils except Kureb lack irregular intermittent Bh bodies in the E/Bh horizon. Kureb soils lack argillic horizons. Onslow soils lack an arenic epipedon and contain gray mottles indicative of wetness in the Bt horizon. Seagate and Valhalla soils have continuous Bh horizons. Seagate soils have poorer drainage. GEOGRAPHIC SETTING: Baymeade soils occur on broad, gently sloping surfaces of the lower Coastal Plain, generally above 20 feet. Slopes range from I to 12 percent. They formed in (stratified) interbedded sandy and loamy Coastal Plain sediments. The mean annual precipitation ranges from 47 to 60 inches and mean annual temperature ranges from 53 to 74 degrees F. GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Kureb and the Blanton, Foreston, Goldsboro, Lakeland, Leon, Norfolk and Rimini series. Blanton soils have a Grossarenic epipedon. Foreston, Goldsboro and Norfolk lack an arenic epipedon. Lakeland soils lack light gray E horizons and an argillic horizon. Leon and Rimini soils have continuous Bh horizons, and the Leon soils have poorer drainage. DRAINAGE AND PERMEABILITY: Well drained; slow runoff; moderately rapid permeability. Measured watertable levels at two sites show that the water table is 45 to 60 inches below the surface in December to April and other wet periods. USE AND VEGETATION: Most of these soils are in forest of mixed hardwood and pine. Native vegetation is turkey oak, long leaf pine, dwarfed huckleberry, small myrtle, wire grass, and astor. Large areas are in residential and urban uses in New Hanover County. http://www2.ftw.nres.❑sd,i.gov/osd/dat/B/BAYMEADE.html Hanover Design Services '' 23 Floral Pkwy.
