survey mapping (USDA 1989), the Site contains two soil series: Torhunta fine sandy loam (Typic humaquepts) and Pantego fine sandy loam (Umbric Paleaquults). Site soils are depicted on Figure 4(Appendix A) and described in Table 1. Restorable portians of the Site are predominantly underlain by soils of the Torhunta series. Torhunta soils are 80 percent hydric soils that are characterized by a dark gray matrix. Soils have been impacted by land clearing, ditching, and till from row plant production. Table 1. NRCS Soils Ma Soil Series H dric % Torhunta 80 Pantego 85 within the Site This series consists of nearly level stream terraces and upland bays Typic in the Coastal Plain. Torhunta soils are very poorly drained, have Humaquepts moderately rapid permeability, and a seasonal high water table at the surface for 2 to 6 months annuall . This series consists of very poorly drained, moderately permeable Umbric soils that formed in thick loamy sediments on the Southern Coastal Paleaquults Plain and Atlantic Coast Flatwoods. The water table is at or near the surface during the wet season. Detailed soil mapping conducted by licensed soil scientists in January 2011 indicate that the entire 17- acre Site is currently underlain by nonriparian hydric soils of the Torhunta and Pantego Series (Figures 4 and 5, Appendix A). A detailed soil profile includes the following. Soil Profile 1 0 to 3 inches; black (lOYR 2/1) sandy loam 3 to 6 inches; black (SYR 2.5/1) sandy loam 6 to 15 inches; gray ( lOYR 5/ 1) sandy loam 15 to 16+ inches; light gray (lOYR 7/2) sandy loam �i��.��',�y�•� �� "s, .i ��_ _ � . . �. , . . , , . „ . . . 2.5 Hydrology Soil Profile 2 0 to 10 inches; black (lOYR 2/1) sandy loam 10+ inches; black (lOYR 2/1) sandy loam; common medium distinct brown (lOYR 4/3) mottles ,A'��6�T9��t� p ..> , s� .. s ;- �`..�'/ "" . �: � � . .3y � .,�.. r� i :� �. As stated in the USDA Soil Survey of Craven County, NC groundwater levels for the Site and surrounding area are at or near the surface during the dormant and early growing season, and is fed explicitly by rain events. Torhunta and Pantego are both nearly level, slowly permeating soil types which drain poorly. The current ditching of the Site has capped surface and sub-surface hydrology.

hydric and is located on Nearly level stream terraces and upland bays wrthm the Coastal Plam Torhunta soils are very poorly dramed have moderately rapid permeabihty and a seasonal h�gh water table at the surface for 2 to 6 months annually Characteristically Torhunta fne sandy loam is defined at the surface by a black fine sandy loam to a depth of 12 mches From 12 to 37 inches the subsoil turns to a dark drown sandy loam Pantego fine sandy loam consists of very poorly dramed moderately permeable soils that formed m th�ck loamy sediments on the Southern Coastal Plam and Atlantic Coast Flatwoods The water table is at or near the surface durmg the wet season As described m the Craven County USDA Soil Survey Pantego fne sandy loam is typically black fine sandy loam to a depth of 15 mches Subsoil extends to 62 mches and is characterized by dazk gray sandy clay loam m upper layers to gray sandy clay m lower layers Hvdrology As stated m the USDA Soil Survey of Craven County NC

elevation of the water table near a pumpmg well as time progresses Slrver Moon Non ripanan Wettand Mitigat�on Site pg 17 MrtigaUon Plan December 2011 The Boussmesq equation was applied to Srte drtches to predict the lmear distance of groundwater drawdown that exceeds 1 foot for 7 5 percent of the growmg season The percentage of the growmg season (7 5 percent) was selected based upon gu�dance from the Corps of Engmeers Wetland Delmeation Manual (Environmental Laboratory 1987) The equation is solved for wetland impacts with data for the followmg variables 1) equivalent hydraulic conductivity 2) dra�nable porosity 3) and estimated depth to the impermeable layer or aquiclude 4) the time duration of the drawdown 5) target water depth (1 foot below the soil surface) and 6) mmimum drtch depth

determination/delineation would be required The site is row crop (corn) ag land that has been extensively ditched/drained if I recall correctly Thom Steffans of the Washington USACE Office wanted to talk it over with his folks before making a decision I got a call from Restoration Systems this morning and they were asking if a decision had been made As you would expect they would prefer that the

The Site is located approximately 4 miles east of Dover in western Craven County and within the Targeted Local Watershed 03020202080010. The Site encompasses approximately 17.1 acres of land used for row crop production. Within the Site, 17.1 acres of non-riparian hydric soils have been cleared and ditched. A total of 14 non-riparian wetland mitigation units (WMUs) are being offered. Located within an interstream flat north of Core Creek and adjacent to the rim of a Carolina bay the Site has been cleared of native forest vegetation, ditched to remove groundwater hydrology, and is currently utilized for row crop production. Construction activities at the site will re-elevate the groundwater table to historic conditions prior to the ditching of the site. Construction methods were based primarily on carbon copy method for wetland restoration, mimicking reference (relatively undisturbed) wetland in the region. The project is designed to maximize groundwater re-charge and water quality benefits in the Yadkin River Basin.
