Print Name: * Barrett Jenkins Signature: * 'a tterr-erArd June 16, 2022 From: Barrett Jenkins, Project Manager, Restoration Systems To: Katie Merritt, NCDWR, Nutrient Offset Banking SUBJECT: Post Construction Documentation Memo for the Raleigh Farm Umbrella Mitigation Banking Instrument for Nutrient Offset and Riparian Buffer Mitigation Credits pursuant to the Neuse River Basin Nutrient Management Strategy, Phase BC Bank Parcel, NCDWR#2019-1692v5 In accordance with section VI. Post Construction Documentation for each Bank Parcel, As -Built Reports, B., of the above referenced mitigation bank's instrument, Restoration Systems is providing the following post construction documentation. The Bank Parcel is in Wake County North of Battle Bridge Road and both East and West of Mail Plantation Road on property owned by the City of Raleigh at their Neuse River Resource Recovery Facility, which operates as the City's primary municipal wastewater treatment facility. The following more detailed summary of activities is provided and a figure including proposed easement boundary, location of installed monitoring plots, riparian restoration and preservation activities are provided as attachments at the end of this memo. The conservation easement has not been recorded due to a long approval process with the City. The easement boundary as proposed and planted is marked in the field with t posts. This memo is presented to allow DWR to visit the site earlier in the growing season if needed. The following Table 1 is derived from the BPDP and summarizes proposed restoration activities with status updates in BOLD. Table 1: Update on restoration activities Restoration Plan Activity Phase Specific Actions The City, who actively self -manages the farm operations, will treat fescue within the Parcel ahead of Herbaceous planting efforts. Treatment will consist of a broadcast application using Roundup Custom Treatment (Glyphosate) at a rate of 3% and a surfactant of AgriDex at a rate of 1%, per acre, mixed with water. Update: The City treated field grasses as proposed in 2021 prior to planting. Remove existing farm paths within the proposed easements by deep ripping to break soil compaction associated with equipment and vehicle use. NRRRF will establish new roads Removal of dependent on future use and need outside of the Site's proposed easements. Existing Update: The proposed conservation easement footprint in agriculture was ripped with a Infrastructure chisel plow in January of 2022 prior to planting. - Remove large debris from the easement as is feasible and without damaging the existing riparian buffer Feature 3A, Phase B. Update; It was determined removal of this debris Restoration Plan Activity Phase Specific Actions without damaging the existing riparian buffer would be infeasible. This does not contradict the objectives of the project. Within the Site's proposed conservation easements: - Treat Bermuda and fescue grass species within active pasture areas (see Herbaceous Treatment note above). Update: Complete - Site -wide discing of agricultural and pasture areas ahead of planting — discing will occur parallel to the Site Features, promoting floodwater attenuation by increasing frictional resistance of Riparian floodwaters crossing Parcel floodplains. Restoration Update: Complete - Establishment of a native herbaceous community via site -specific seed mix (See Planting Plan — Section 3.3.1) Update: The site was seeded at a rate of 11b/acre with the seed mix detailed below in April. - Establishment of a native hardwood forest via the planting of bare -root saplings from the top of bank out a maximum of 200' along Parcel Features — Section 3.3 Planting Plan Update: The site was planted with bareroot trees in early February 2022 as detailed below. Planting Summary: Restoration portions of the larger approximately 107.9 acre proposed conservation easement area have been planted with bare root hardwood species. In total approximately 57 acres were planted at an average density of approximately 680 stems per acre. Percent of species planted varied slightly from what was proposed in the BPDP and is listed below. Tree planting was completed on between February 12 and March 9, 2022. Table 2.
