LIDAR Map Selma Mill PRE-PROSPECTUS Stream Mitigation Bank / May 2014 I INTRODUCTION 1.1 Project Description The =Selma Mill Stream Mitigation Project is located on a,25.6 -acre site immediately north of Selma in Johnston County, NC Several unnamed tributaries that traverse the site that exhibit diminished habitat and stability as�a result of past and on -going agricultural activities and impervious watershed conditions. The site was identified by EBX -Neuse I, LLC as having potential to help meet the compensatory mitigation requirements for stream impacts in hydrologic unit 03020201,of °the Neuse River Basin. The proposed project involves the restoration and enhancement of'5,604 linear feet of streams that have been disturbed by agricultural activities, active cattle grazing, and watershed land use. The conceptual,design presents 3,333 linear feet of stream, restoration and 2,271 linear feet otstream� enhancement, generating 4,762 Stream Mitigation Units (SMU). The Selma Mill project will also be utilized to provide 20.9 buffer mitigation units through the NC Division of Water Resources (DWR) Neuse Riparian Buffer Mitigation program. The'buffer °mitigation will be developed through a separate banking instrument. 1.2 Project Location The Selma Mill Mitigation Bank is located'in Johnston County immediately north,of Selma, NC'(Figure 1). The coordinates of the site are 35.547574 °N and - 78.283716 °W. To access the Site from Selma travel north on NC HWY 96 (N Sumner Street). The site is on the left side-of the road beginning immediately north of W Chestnut Street. The,site extends approximately 2,300 feet,north on the left side of NC HWY 96. A tributary crosses NC HWY 96 approximately 1,900 feet.north of W Chestnut Street. 1.3 Service Area 'The Selma Mill Mitigation Site will provide stream mitigation credits to offset unavoidable impacts,to aquatic resources within the Upper Neuse subbasin (8 -digit USGS HUC 03020201). 1.4 Purpose and Objectives The purpose of the proposed Bank is to generate compensatory mitigation credits for inclusion in -the Neu -Con Umbrella Mitigation Bank in hydrologic unit 03020201 of the Neuse River Basin The project goals address stressors identified in the watershed, and include the following• • Nutrient, removal, • Sediment removal, • Stormflow attenuation, • Filtration of runoff, and • Improved aquatic and terrestrial habitat. The project goals will be addressed through the following project objectives: • Construction of stable stream channels; • Stabilization of existing stream,channels, Selma Mill PRE- PROSPECTUS Stream Mitigation Bank 1 May 2014 • Buffer enhancement and restoration, • Addition of large woody debris such as log vanes, log weirs, and root wads, • Construction of trash removal device, and • Stormwater control from urban watershed. 1.5 Site Ownership The land required for,the construction, management, and stewardship of this mitigation project includes portions of the parcels listed in Table 1.

The delineation will be approved by the,USACE during,the initial environmental screening phase,of the project. The stream channels were classified using North Carolina Division of Water Quality methodology. 3:1.1 Site Mapped Soil Series The Johnston County Soil Survey,shows thirteen mapping units across the,project site Map units include ten soil series and borrow pits (Figure 5) The upland soils found in this-area of the county formed in sandy sediments from marine.and fluviomarine deposits or loamy alluvium. The upland soils at this site are on a river terrace above the active floodplain The soil series found on the site are described'below and summarized in Table 2 Table 2. Mapped Soil Series 3.2 Vegetation Current land use around,the project'is primarily residential, pasture, agriculture, and forestry Land use immediately surrounding the project includes residential, pasture, and row crops Within the project easement two prominent vegetative communities are present: active pasture.and row crops. Exotics species are also present, including Chinese privet (Ligustrum sinense). 3.3 Constraints The site is easily accessible from NC,HW,Y 96 The proposed project is constrained by- existing culvert elevations beneath W'Chestnut Street and NC HWY 96.

There are no major constraints to construction of the Site The Site is readily accessible from N Sumner Street via access roads on the property. One existing stream crossing will remain along Reach A to allow the landowner access to the agriculture fields and adjacent, property. The project area is not within a,FEMA 100 -year flood zone (Figure 6). Selma Mill PRE- PROSPECTUS Stream Mitigation Bank 5 May 2014 4 PROPOSED BANK CONDITIONS 4.1 Conceptual Mitigation'Plan The Selma Mill stream mitigation project presents the opportunity to provide up to 4,762 SMU through two options.

Option,2 is „presented,as,an alternative`to account for potential landowner constraints with the Janice B. Coats Revocable Trust parcel. The ultimate extents of the Bank will be contingent on potential uplift, IRT coordination, and landowner negotiation Selma Milli PRE- PROSPECTUS Stream Mitigation Bank 6 May 2014 C 4.1.1 Stream Restoration Current stream conditions along,the proposed restoration, reaches,demonstrate significant habitat degradation as a result of impacts from livestock, historic land uses, and impervious, watershed conditions. Additionally, the riparian buffer is',in poor condition throughout most of the project,area due to grazing and "agriculture. The Selma'Mill project,will include Priority Level I stream restoration and stream enhancement Levels I and II. Addition a lly,.stormwater controls and trash removal may be provided by construction of a BMP. Stream restoration efforts will be accomplished through analyses of geomorphic conditions and watershed characteristics. The design approach will apply a combination of analytical and reference reach based design methods that meet objectives commensurate with both ecological and geomorphic improvements. Proposed treatment activities may range from minor bank grading and planting (enhancement) to re,- establishing stable planform and hydraulic •geometryi(restoration).;For reaches requiring full restoration or extensive enhancement, natural design concepts will be applied and verified through rigorous engineeringfanalyses,and modeling. The objective of this approach is to design a geomorphically stable channel that provides habitat improvements and ties into the existing landscape. Planted vegetation will be based on target;reference communities. 4.1.2 Monitoring Stream stability and`vegetation survival will be monitored across both the restoration and enhancement areas of the Sitelo determine the success of the stream and buffer mitigation .Stream stability will be monitored with cross section surveys and visual assessment stream walks. Vegetation survival rates will be monitored using vegetation plots. If constructed, BMP,performance will be determined through waterquality Potential parameters include Total Nitrogen and "Total "Phosphorous with samples taken upstream of the project, at the BMP outlet, and in the downstream channel.
