1 Project Summary
Water and Land Solutions, LLC (WLS) completed the construction and planting of the Lake Wendell
Mitigation Project (Project) full-delivery project for the North Carolina Department of Environmental
Quality (NCDEQ), Division of Mitigation Services (DMS) in March 2018. The Project is located in Johnston
County, North Carolina between the Community of Archer Lodge and the Town of Wendell at 35˚ 44’
14.60’’ North and 78˚ 21’ 13.69’’ West. The Project site is located in the NCDEQ Sub-basin 03-04-06, in
the Upper Buffalo Creek Sub-watershed 030202011502 study area for the Neuse 01 Regional Watershed
Plan (RWP), in the Wake-Johnston Collaborative Local Watershed Plan, and in the Targeted Local
Watershed 03020201180050, all of the Neuse River Basin.
The Project involved the restoration, enhancement, preservation and permanent protection of five
stream reaches (R1, R2, R3, R4, and R5) and their riparian buffers, totaling approximately 4,269 linear feet
of streams and approximately 489,542 square feet of riparian buffers. The Project construction and
planting were completed in March 2018 and MY1 monitoring activities occurred between March and
November 2018 (Table 2). This report documents the completion of and presents the data for the first
year of monitoring (MY1). The Project meets the MY1 success criteria for vegetation. Based on these
results, the Project is expected to meet the Year 2 Monitoring success criteria in 2019.
2 Project Background
2.1 Project Location, Setting, and Existing Conditions
The Lake Wendell Mitigation Project (Project) site is located in the Upper Buffalo Creek Sub-watershed
030202011502 study area for the Neuse 01 Regional Watershed Plan (RWP), in the Wake-Johnston
Collaborative Local Watershed Plan, and in the Targeted Local Watershed 03020201180050, all of the
Neuse River Basin. The Project site is situated in the lower piedmont where potential for future
development associated with the I-540 corridor and rapidly growing Johnston County area is imminent,
as described in the Regional Watershed Plan (RWP) for the Upper Neuse River Basin within Hydrologic
Unit (HU) 03020201.
The RWP identified and prioritized potential mitigation strategies to offset aquatic resource impacts from
development and provided mitigation project implementation recommendations to improve ecological
uplift within the Neuse 01 subbasin, which included traditional stream and wetland mitigation, buffer
restoration, nutrient offsets, non-traditional mitigation projects such as stormwater and agricultural
BMPs, and rare, threatened, or endangered (RTE) species habitat preservation or enhancement.
The project included five stream reaches (R1, R2, R3, R4, and R5) which involved the restoration,
enhancement, preservation and permanent protection of approximately 4,269 linear feet of streams and
approximately 489,542 square feet of riparian buffers permanently protected by a recorded conservation
easement (11.97 acres). The catchment area is 102 acres and has an impervious cover less than one
percent. The dominant land uses are agriculture and mixed forest. Prior to Project construction, livestock
had access to all Project streams, except R4, and the riparian buffers were less than 50 feet wide.
2.2 Mitigation Project Goals and Objectives
WLS established project mitigation goals and objectives based on the resource condition and functional
capacity of the watershed to improve and protect diverse aquatic resources comparable to stable

headwater stream systems within the Piedmont Physiographic Province. The proposed mitigation types
and design approaches described in the final approved mitigation plan considered the general restoration
and resource protection goals and strategies outlined in the 2010 Neuse River Basin Restoration Priority
Plan (RBRP). The functional goals and objectives were further defined in the 2013 Wake-Johnston
Collaborative Local Watershed Plan (LWP) and 2015 Neuse 01 Regional Watershed Plan (RWP) and
include:
• Reducing sediment and nutrient inputs to the upper Buffalo Creek Watershed,
• Restoring, preserving and protecting wetlands, streams, riparian buffers and aquatic habitat,
• Implementing agricultural BMPs and stream restoration in rural catchments together as “project
clusters”.
With regards to riparian buffer mitigation, the following site specific goals were developed to address the
primary concerns outlined in the LWP and RWP and include:
• Restore and protect riparian buffer functions and habitat connectivity in perpetuity by recording
a permanent conservation easement,
• Implement agricultural BMPs to reduce nonpoint source inputs to receiving waters.
To accomplish these site-specific goals, the following objectives will be measured and included with the
performance standards to document overall project success:
• Increase native species riparian buffer vegetation density/composition along streambank and
floodplain areas that meet requirements of a minimum 50-foot-wide and 260 stems/acre after
monitoring year 5,
• Prevent cattle from accessing the conservation easement boundary by installing permanent
fencing and reducing fecal coliform bacteria from the pre-restoration levels.
2.3 Project History, Contacts, and Timeframe
The Project will provide riparian buffer mitigation credits in accordance with North Carolina
Administrative Code (NCAC), “Consolidated Buffer Mitigation Rule”, Rule 15A NCAC 02B .0295, effective
November 1, 2015. Riparian buffer mitigation site viability was confirmed by DWRs April 28, 2016 letter
entitled “Site Viability for Buffer Mitigation & Nutrient Offset – Lake Wendell Located Near 2869 Wendell
Road, Wendell, NC, Johnston County”. The referenced site viability letter included a determination by
DWR that Project Reaches R1, R2, R3 and R4 were either intermittent or perennial. A separate request
for Stream Origin/Buffer Applicability Determination for Potential Mitigation for Project Reach R5 was
submitted to DWR on May 18, 2017, as required under the referenced site viability letter. On June 1, 2017
DWR performed the requested determination and Reach R5 was determined to be intermittent, as
communicated in the DWR June 8, 2017 letter entitled “On-Site Stream Determination for Applicability to
the Neuse Riparian Buffer Rules and Water Quality Standards (15A NCAC 02B.0233)”, therefore confirming
Reach R5’s eligibility for riparian buffer mitigation. See Appendix D for DWR correspondence and approval
letters.
In addition to DWR correspondence and approval, WLS investigated on-site jurisdictional waters of the US
(WOTUS) using the US Army Corps of Engineers (USACE) Routine On-Site Determination Method. This
method is defined in the 1987 Corps of Engineers Wetlands Delineation Manual and subsequent Eastern
Mountain and Piedmont Regional Supplement. Determination methods included stream classification
Water & Land Solutions

Lake Wendell Mitigation Project (Riparian Buffer Mitigation)
FINAL Monitoring Report Year 1 Page 3

utilizing the NCDWQ Stream Identification Form and the USACE Stream Quality Assessment Worksheet.
The results of the on-site field investigation indicated that there are two jurisdictional stream channels
located within the proposed project area. The main unnamed tributary (R1, R2, R4) was determined to
be perennial while R5 was determined to be intermittent. USACE representative John Thomas verified
Jurisdictional Determinations during a field visit on October 16, 2016.
The final mitigation plan and PCN were submitted to DMS August 25, 2017 for submission to DWR and
the NCIRT. The Section 404 General (Regional and Nationwide) Permit Verification was issued October 5,
2017. Project construction started on November 13, 2017 and mitigation site earthwork was completed
on March 13, 2018, and mitigation site planting was completed on March 30, 2018, both by RiverWorks
Construction. Trueline Surveying, PC completed the as-built survey in June 2018. WLS completed the
installation of baseline monitoring devices on April 19, 2018 and the installation of survey monumentation
and conservation easement boundary marking on June 7, 2018.
The project background and attribute summary is presented in Table 1. Refer to Figure 1 and Table 2 for
the project areas and buffer asset information. Relevant project contact information is presented in Table
3.
3 Project Mitigation Components
3.1 Riparian Buffer Mitigation Types and Approaches
Riparian buffer mitigation included restoring, enhancing and preserving the riparian buffer functions and
corridor habitat. The project included planting to re-establish a native species vegetation riparian buffer
corridor, which extended a minimum of 50 feet from the top of the streambanks along each of the project
reaches, as well as permanently protecting those buffers with a conservation easement. Many areas of
the conservation easement had riparian buffer widths greater than 50 feet established along one or both
streambanks to provide additional functional uplift. The only exception is at the upstream end of Reach
R1, where the width of the proposed left riparian buffer varies between 20 feet and 29 feet from the left
top of bank. This narrow area of proposed riparian buffer is due to the site constraint caused by an existing
residential structure. For project reaches proposed for restoration and enhancement, the riparian buffers
were restored through reforestation of the entire conservation easement with native species riparian
buffer vegetation (Appendix C). For project reach sections proposed for preservation, the existing riparian
buffers will be permanently protected via the recorded conservation easement. Additionally, permanent
fencing was installed along with alternative watering systems to exclude livestock from the restored
riparian buffer and conservation easement areas. The permanent fencing system consisting of woven
wire fencing was installed to NRCS technical standards in the pasture areas along and outside of the
northern conservation easement boundaries of Reaches R1, R2, and R3. Table 1 and Figure 1 (Appendix
A) provide a summary of the project components.
3.1.1 Tree and Shrub Planting Approaches
The riparian buffer planting zones for the project included the streambanks, floodplain, riparian wetland,
and upland transitional areas. The as-built planting boundaries are shown on the as-built vegetation plans
in Appendix E and Figure 1. Plantings were conducted using native species bare-root trees and shrubs,
live stakes, and seedlings that were generally planted at a total target density of 680 stems per acre. WLS
implemented a riparian buffer planting strategy that includes a combination of overstory, or canopy, and
understory species. The site planting strategy also included early successional, as well as climax species.
Water & Land Solutions

Lake Wendell Mitigation Project (Riparian Buffer Mitigation)
FINAL Monitoring Report Year 1 Page 4

The vegetation selections were mixed throughout the project planting areas so that the early successional
species will give way to climax species as they mature over time.
3.1.2 Temporary and Permanent Seeding Approaches
Permanent seed mixtures of native species herbaceous vegetation and temporary herbaceous vegetation
seed mixtures were applied to all disturbed areas of the project site. Temporary and permanent seeding
were conducted simultaneously at all disturbed areas of the site during construction utilizing mechanical
broadcast spreaders. The as-built re-vegetation plan lists the utilized species, mixtures, and application
rates for permanent seeding.
3.1.3 Invasive Species Vegetation Treatment
During the project construction, invasive species exotic vegetation was either mechanically removed or
chemically treated both to control its presence and reduce its spread within the conservation easement
areas. During MY1 vegetation assessment, one area of concern was observed along R1 buffer as shown
on the CCPV. This area was utilized as a temporary staging area during construction and contains invasive
species vegetation (kudzu) along the right buffer. This area will be treated during MY2 monitoring and
documented in the subsequent annual report.
4 Performance Standards
The applied success criteria for the Project will follow necessary performance standards and monitoring
protocols presented in final approved mitigation plan. Annual monitoring and semi-annual site visits will
be conducted to assess the condition of the project throughout the monitoring period. Monitoring
activities will be conducted for a period of five (5) years. Specific success criteria components and
evaluation methods are described below.
4.1 Vegetation
Measurements of the final vegetative restoration success for the project will be achieving a density of not
less than 260, five-year-old planted stems per acre in Year 5 of monitoring. This final performance criteria
shall include a minimum of four (4) native hardwood tree species or four (4) native hardwood tree and
native shrub species, where no one species is greater than fifty (50) percent of the stems. Native
hardwood tree and native shrub volunteer species may be included to meet the final performance criteria
of 260 stems per acre. In addition, diffuse flow of runoff shall be maintained in the riparian buffer areas.
5 Monitoring Year 1 Assessment and Results
Annual monitoring was conducted during MY1 in accordance with the monitoring plan as described in the
approved mitigation plan and was intended to document the site improvements based on restoration
potential, catchment health, ecological stressors and overall constraints. All of the monitoring device
locations are depicted on CCPV (Figure 1) and MY1 monitoring data results are listed in the appendices.
The Project meets the MY1 success criteria for vegetation.
5.1 Vegetation
Vegetation monitoring for MY1 was conducted utilizing the seven (7) vegetation monitoring plots, with
monitoring conducted in accordance with the CVS-EEP Level I & II Monitoring Protocol (CVS, 2008) and
DMS Stream and Wetland Monitoring Guidelines (DMS, 2017). See Figure 1 in Appendix B for the
vegetation monitoring plot locations. The MY1 average surviving planted stem density is 480 stems per
Water & Land Solutions

FINAL Monitoring Report Year 1 Page 5

acre, which exceeds the interim measure of vegetative success of at least 260 planted stems per acre at
the end of the fifth monitoring year. The surviving planted stems also include a minimum of four (4) native
hardwood tree species or four (4) native hardwood tree and native shrub species, where no one species
is greater than fifty (50) percent of the stems. Summary data and photographs of each plot can be found
in Appendix 3.
The MY1 vegetation monitoring was also conducted utilizing visual assessment along all of the Project
stream reaches. The results of the visual assessment did not indicate any negative changes to the existing
vegetation community. Additionally, the visual monitoring confirmed that diffuse flow of runoff is being
maintained in the riparian buffer areas.

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.
