Correspondence 1.0 Introduction LI Prqiecl Location and DeserilVion The Forrest Creek Stream Restoration Site (Site) of the Forrest Creek Mitigation Bank (Bank) is located in Orange County North, Carolina within land owned by Milton A. Latta and Sons Dairy Farms, Inc. A permanent conservation casement covers the restored strearn and sun-onrlding riparian buffer. ']'his casement defines the Site' s boundaries, The Site is located approximately seven miles northeast of Hillsborough and six miles northwest of Durham in northeastern Orange County, North Carolina (see Figure 1, Appendix A), The streams lie within USES hydrologic unit 03020201020020 in the Neuse River Basin. The North Carolina Division of Water Quality NCDWQ) classifies the main reach, Forrest Creek, as a WS -11 (water supply 11), HQW (high quality water), and NSW (nutrient sensitive water), The Site includes two strearns. The larger reach (Forrest Creek) flows through the property from north to south and drains a 3. 6 square mile area consisting of predominantly forest and pasture land. "rhe smaller tributary (UIT 1) flows from west to oast before joining with Forrest Creek and drains a 0.1 square mile area consisting of predominantly pasture land. Located in Appendix A is the Forrest Creek Restoration Conservation Easement AS-Built Exhibit (Sheets I through 5). 'The stream restoration work is regulated under the Forrest Creek Mitigation Bank Mitigation Banking Instrument (MBI) signed by the Sponsor and the US Army Corp of Engineers (USACE), the US Environmental Protection Agency (USEPA), the NC Division of Water Quality (now hereby referred to as Division of Water Resources [DWRI), and the NC Wildlife Resources Commission (NCWRC). These agencies comprise the Interagency Review 'ream (IRT), formerly the MBRT, in accordance with Federal guidelines and regulations including the Compensatory Mitigation losses of Aquatic Resources Final Rule, 33 CF R Parts 325 and 332 and 40 CFR Part 230. Restoration work resulted in the restoration of 6, 825 linear feet, endiancernent (Level 1) of' 325 linear feet, and preservation of 3,005 linear feet of stream. With the restoration, water quality has been improved due to a decrease in nutrients, turbidity, and moderation in water temperature, Biochemical oxygen demand has been reduced through filtering in the riparian buffer and riverine wetlands. Potential habitats have been added through the creation of bed features and the reestablishment of riparian vegetative community. The annual monitoring work assesses the Site's strearns, the Forrest Creek main channel and the Unnamed Tributary to Forrest Creek, to determine restoration success, The monitoring plan has been set up based on guidance provided by The Stream Mitigation Guidelines developed by the thifted States Corps of Engineers — Wilmington District (McLendon, et a]. 2003), version 1. 2 11/ 16/ 2006) of the North Carolina Ecosystem Enhancement Program (EEP') document entitled Content, Format, and Data Requirements for EEP Monitoring Reports "', version 2.0 (3/27/2008) of the EEP document entitled "Mitigation Plan Document Format, Data Requirements, and Content Guidance ", and the Forrest Creek Mitigation Bank Mitigation Plan (May 2008). Monitoring has occurred annually for five years and reports have been submitted. Annual monitoring work has included reference photographs, vegetative stein Counts, materials sainpling, site survey,, bankfull event documentation, and visual assessment and mapping of significant features. Year 5, 2012 monitoring was completed on September 18 -19 and October 16, 2012 with the submission of Year 5 Monitoring Report for the Forrest Creek Buffer Mitigation Bank on December 4, 2011 Members of the IRT, more specifically representatives from DWR and USACE, met with EBX-EM, LI...0 (EBX) on-site to evaluate the success of the riparian buffer restoration. Based on the results of the on -site meeting, 'I R requested additional vegetation monitoring for a period of 3 years (DWR Additional Monitoring Required letter, May 3, 2013, I "G R Project # 08 -0229, Appendix E). More specifically, DWR had the following comments, "Significant areas within Zorn l of the riparian buffer along the entire reach of the Forrest. Creek mitigation site appeared to lacy adequate stern couonts most likely due to sail type and hydrology issues. Steers that were present in gone I were mostly small, indicating they may have been part of supplemental planting performed in 010 required by DWQ and ACOE, Action R urrred EBX shall reevaluate Zone l throughout the entire mitigated portions of Forrest. :reek and provide a reraaediation plan sufficient to provide adequate vegetation in Zone 1, Sufficient ground cover should be reestablished in all bare areas and„ where adequate stern counts are absent., EBX shall plant trees that are desirable for that specific soil type and hydrology. l " +Q reconrnrerrds larger trees be planted in some of the most problematic areas along time reach. Modifications to the approved buffer mitigation plan are allowed to provide EB,X with the flexibility of choosing; tree species and vegetation that are more likely to survive and reach. maturity. EBX may make additional recommendations to promote site success. Monitoring reports shall be submitted for 3 more years (2013, 2014, and lll) and shall record only the vegetation conditions along Zone L " This Monitoring deport addresses buffer restoration areas between Stations 214+00 and 232+00, which includes Vegetation Plots 2, 3, and 4. .2 Project Goals and Objectives I'he goals of the project relate to providing ecological improvements to the Site" s streams and riparian buffers through beneficial modifications of °hydrology, water quality, and habitat, Goals, related to hydrology include: • Re- establishing floodplain connection by raising; lied elevations (l:..h'H) or lowering adjacent floodplain (Forrest Creek) • Increasing flood storage by re- establishing floodplain connection Goals related to water duality include: • Deducing turbidity and pollution by reducing sediment and nutrient inputs cattle exclusion) • Deducing water temperatures by providing shading • Increasing / stabilizing oxygen levels by reducing BBD /COIF and increasing rcoxygenating turbulence Goals related to habitat include:. • Improving in stream bed habitat by increasing riffle pool diversity, reducing sediment deposition, and improving low flow water depths • Improving, bank habitat by increasing; stability and woody biomass • Improving; floodplain habitat by establishing inicrotopography and hydrology, removing; invasive vegetation, and increasing habitat diversity • Improving food web dynamics by adding, biornass (such as detritus, coarse woody debris, and leaf matter) and re- establishing floodplain connection The restoration achieves these goals through the following objectives: • Stabilizing channel bed and banks through modifying dimension, pattern, and profile using natural channel design • Installing in_ streani structures such as rock vanes, log vanes, and constrUcted rif'fTes • Raising stream bed elevations or lowering f7oodplains • Restoring soils in riparian buffer by excluding cattle and adding organic components • Removing invasive vegetation • Irlanting native vegetation in riparian buffer • Fencing out livestock. Together, these improvernents have provided functional uplift For the watershed as a whole, 'rhe dimension, pattern, and profile were restored. using, Rosgen priority l and 11 restoration. approaches (Rosgen, David I..,. 1997). The Priority 1 approach was used on the UT to Forrest Creek to raise bed elevations and reconnect the stream to the abandoned floodplai.n. "The Priority 11 approach was used on Forrest Creek to reestablish an active fToodplain at the existing Merl elevation, These n- rethods have decreased stream bank erosion, establish an active fToodplain, reduce channel stress during floods, improve aquatic habitat, and reduce fine sediments, A portion of'Forrest Creek immediately above the restoration reach was enhanced by modifying a downstream crossing that had created ponding upstream of it. The crossing modification reestablished natural flow and will create a natural channel profile. Above the enhancement area, a section of Forrest Greek: has been placed under conservation easement to preserve a f`frnctionat stream channel and riparian buffer.. The remaining impaired riparian buffer was planted as four (4) zones. Zones 1 and 2 are the stream channel and bank zones consisting of tree and shrub species and native herbaceous seeding typically found along stream banks in the region. Live stares comprised the hulk cif' installed species within these crones, .done 3 is the riparian zone consisting of selected tree and shrub species with a range of tolerances to inundation and saturation. Zone 4 is the transitional zone that includes the buffer areas (subject of a separate report prepared for DWR) See Tables l -11T for more information regarding project structure, activity, history, and contacts. .tf �'e etatirrrr rmrrrditiarrr rrrarl !l�rrrrr rar�risrrrr Current stem counts (i,e. stem is defined as ,single living tree species) were calculated using vegetation plot monitoring Plata. Success will be defined as the survival of a rnfninnrm density of 320, trees and shrubs per acre, As for Monitoring Year ti, monitoring was conducted ,for three (3) vegetation plots (Vegetation plots 2, 3, and 4) located between Stations 214400 and 324 -00. Monitoring Year Cr field activities were conducted on October 10 and October 74, 2013.
