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

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.
