Re: Site Viability for Buffer Mitigation & Nutrient Offset — Lake Wendell
Located near 2869 Wendell Rd, Wendell, NC
Johnston County
Dear Mr. Hunt,
On April 8, 2016, Katie Merritt, with the Division of Water Resources (DWR), assisted you and
others from Water & Land Solutions, LLC at the proposed Lake Wendell Mitigation Site (Site)
in Wendell, NC. The Site is located in the Neuse River Basin within the 8 -digit Hydrologic Unit
Code 03020201. The Site is being proposed as part of a full -delivery stream restoration project
for the Division of Mitigation Services (RFP #16-006477). The Interagency Review Team (IRT)
was also present onsite. At your request, Ms. Merritt performed a site assessment of features onsite
to determine suitability for buffer and nutrient offset mitigation. Features are more accurately shown
in the attached maps signed by Ms. Merritt on April 20, 2016. If approved, mitigating this site could
provide stream mitigation credits, riparian buffer credits and/or nutrient offset credits.
Ms. Merritt's evaluation of features from Top of Bank (TOB) out to 200' for buffer and nutrient
offset mitigation pursuant to Rule 15A NCAC 02B .0295 (effective November 1, 2015) and Rule
15A NCAC 02B .0240 is provided in the table below:

'Subjectivity calls were determined using the 1:24,000 scale quadrangle topographic map prepared by USGS and the most
recent printed version of the soil survey map prepared by the NRCS
2For nutrient offset viability to be determined, the landowner must provide proof in writing that the land is being used for
agriculture or has been used for agriculture previously (prior to rule baseline). Dates, supported by photos or other
written records, must be included to confirm that the uses of the open fields onsite are/were for hay crop cultivation/row
crop/cattle.
'Feature has been piped or is a pond, but has potential for buffer mitigation if feature is restored into a stream.
Maps showing the project site and the features are provided and signed by Ms. Merritt on April
20, 2016. This letter should be provided in all future mitigation plans for this Site. In addition,
all vegetative plantings, performance criteria and other mitigation requirements for riparian
restoration, enhancement and preservation must follow the requirements in 15A NCAC 02B
.0295 to be eligible for buffer and nutrient offset credits. Where buffer and nutrient offset credits
are viable in the same area, only one credit type is allowed to be generated for credit, not both.
For any areas depicted as not being viable for nutrient offset credit, one could propose a different
measure other than riparian restoration enhancement, along with supporting calculations and
sufficient detail to support estimates of load reduction, for review by the DWR to determine
viability for nutrient offset according to 15A NCAC 02B .0240.
Please contact Katie Merritt at (919)-807-6371 if you have any questions regarding this
correspondence.
Sincerely,
Karen Higgins, Supervi
