Arrington Bridge Mitigation Bank Phase I & II sites were each granted a conservation easement, recorded around the restoration areas within the overall bank parcel. Located within the Neuse River Basin (below Falls Lake), stormwater runoff from the site was draining into an unnamed tributary of the Neuse River, classified as Class C and Nutrient Sensitive Waters. The bank’s purpose is to improve water quality within the Neuse River watershed by restoring hardwood forest in riparian areas and along with other conveyances. RES’ restoration activities include nearly 11 acres of riparian buffer restoration and 47 acres of nutrient offset. Credits derived from the Arrington Bridge sites provided mitigation for unavoidable impacts resulting from development activities.

The Arrington Bridge III wetland mitigation project is located on a 57.40 acre site three miles southwest of Goldsboro in western Wayne County, NC. One unnamed channelized drainage feature that traverses the site exhibited diminished habitat value as a result of past and on-going agricultural activities. RES identified the site as having potential to help meet the compensatory mitigation requirements for wetland impacts in hydrologic unit 03020201 of the Neuse River Basin.

This project involves the restoration and enhancement of 41.24 acres of wetlands that had been disturbed by historic mining, agricultural activities, and active cattle grazing. The project presents 29.37 acres of wetland restoration and 11.87 acres of wetland enhancement, generating 32.51 Wetland Mitigation Units (WMU’s). This mitigation project is the third of three phases.  Due to its location and improvements, the project provides numerous ecological and water quality benefits within the Neuse River Basin. While many of these benefits are limited to the project area, others, such as pollutant removal and improved aquatic and terrestrial habitat, have more far-reaching effects.

The objective for this restoration project was to restore a continuous bottomland wetland system and enhance the hydrology of existing wetlands. The design was based on reference conditions, USACE guidance (USACE, 2005), and criteria developed during this project to achieve success. Initial site design included the construction of three slough habitats to increase surface water storage and include patches of habitat more typical of reference Cypress-Gum Swamps. Through coordination with the Interagency Review Team (IRT) and the Seymour Johnson Air Force Base (SJAFB), it was requested that the restoration design minimize standing water features that attract birds. Therefore, the slough features and Cypress-Gum Swamp wetlands have been removed from the design and the restoration plan is now exclusively bottomland hardwood forest. Additional project objectives include restoring native vegetation, ensuring hydraulic stability, and eradicating invasive species.

The Baileyton Mitigation Bank is located on 231 acres of a former golf course and agricultural pasture land. Due to previous land use practices, onsite streams have experienced severe degradation, loss of riparian buffers, and direct livestock access to stream channels. Streams chosen for restoration were characterized by bank erosion, loss of floodplain connection, and general instability caused by ongoing channel evolution.

RES is incorporating natural channel design and construction techniques to restore 2.3 miles of degraded and piped headwater intermittent and perennial streams and riparian habitat. The mitigation and restoration activities will generate 9,265 stream credits in the Nolichucky Watershed of Eastern Tennessee. The service areas will also include Holston, Lower French Broad, Nolichucky, Pigeon, South Fork Holston, Upper French Broad, and Watuaga watersheds.

The goal of this Bank was to re-establish, rehabilitate and enhance sustainable bottomland hardwood wetland ecosystems that exhibit natural species composition and to support wildlife habitat typical of healthy bottomland hardwood forests of the lower Mississippi River for compensatory mitigation purposes. The restoration, enhancement, and preservation of forested wetland ecosystems were accomplished through (1) the conversion of pasturelands underlain by hydric soils, and (2) the conversion of areas dominated by existing bottomland hardwood forests that were of relatively low-quality habitat resulting from altered surface hydrology and/or invasive species composition. Through these improvements, the Bank sustains wetland functions, values, and services in accordance with an approved plan. The functional benefit to the Lake Pontchartrain Basin includes an increase in the quantity and quality of forested wetland habitat for resident and migratory wildlife and the conversion of the Bank to a more natural ecosystem. The Bank also benefits the Bayou Manchac watershed through the retention of surface water runoff, streamflow maintenance, nutrient cycling, aquatic productivity, improved plant and wildlife habitat, and the reduction of non-point source pollution (nutrients and suspended solids) originating from agricultural and industrial areas in St. Gabriel, Louisiana.

The Bayou Paul Mitigation Bank restored a forested wetland ecosystem by rehabilitating and maintaining wetland functions, values, and services from land in agriculture. The added value to the Lake Pontchartrain Basin from this project includes increased forested wetland habitat for resident and migratory wildlife, decreased fragmentation of forested wetlands by linking this site with other conservation areas of the Spanish Lake/Bluff Swamp area, increased stormwater attenuation and water purification, increased transpiration within the hydrologic cycle, increased sequestration of carbon and other materials in the planted trees, and increased output of detritus to downstream fisheries resources. In the future, as more areas are developed within the drainage area (agriculturally, commercially and/or residentially), the Bayou Paul Mitigation Bank will provide a greater functional value to the reduction of flooding and point source pollution within the Amite River drainage and subsequently, the Lake Pontchartrain Basin.

RES worked diligently to deliver a custom turkey solution within 90 days for this schedule-driven pipeline. This Permittee’s project spanned 320 miles of 24-inch pipeline, originating in Donaldsonville, LA and terminating in Hastings, TX. RES worked closely with Denbury’s trusted consultants to assess impacts to wetlands and convert this data to an offset requirement. RES located and acquired land commensurate with the restoration preferences of the lead regulatory agency. Finally, RES developed a mitigation plan and obtained regulatory approval within the client’s accelerated timeframe. RES executes ongoing maintenance and monitoring for the client corresponding with its regulatory agreements.

The Bank provides 278.1 acres of Bottomland Hardwoods to compensate for unavoidable wetland impacts for the Vermilion-Teche Basin.

The Bank provides 178.4 acres of bottomland hardwood, bald cypress-tupelo swamp, and fresh marsh to compensate for unavoidable wetland impacts for the Terrebonne Basin watershed area. The site has rehabilitated 104.7 ac of bald cypress-tupelo gum swamp, 53.7 ac of freshwater marsh and 18.2 ac of bottomland hardwood forest wetlands.

The goal of this 48.91 acre nutrient bank located in Culpeper County is to reduce nutrient (phosphorus) and sediment loading into the Rappahannock Watershed via the conversion of active agricultural land into forest; and generate non-point nutrient credits for transfer under existing and future federal, state and local law, programs, regulations and guidance. The site primarily consists of hay field. The land use conversion including Phase I and Phase II will generate 188.30 pounds of nitrogen reduction and 47.93 pounds of phosphorus reduction. Phase I has been completed on 10.26 acres of hay field generating 39.50 pounds of nitrogen and 10.05 pounds of phosphorus credits.

The BHP Terrebonne Biodiversity and Resiliency Projects employ cypress swamp plantings and marsh terrace creation – both proven ecological restoration approaches that improve the quality of lands and waters that support human, animal, and marine populations, especially along Louisiana’s fragile, eroding coastline.

These projects maintain the values of the ecosystem as larger-scale public projects in the state’s coastal master plan come online over time. Once completed, the projects will restore 125 acres of wetlands, with an estimated economic value of $1.2 million per year, 280 tons of carbon sequestered per year, and the elimination of up to 265 pounds of phosphorus and 10,600 lbs of nitrogen each year to improve water quality in those areas.

The projects will be the first two listed in America’s Wetland Conservation & Restoration Registry. This Registry is an inventory and reporting of private projects, consistent with Louisiana’s coastal master plan, that has been completed or planned and available for private sponsorship and funding.

As an integral partner in the project, RES is restoring the historic Cypress-Tupelo Swamp habitat through the planting of 30,000 restorative cypress trees, plus invasive species management, with the goal set on bringing the area back to its historic state. Additionally, RES designed, permitted, and is constructing a 25-acre marsh terrace with 5,000 cypress trees and 35,000 marsh grass plugs. Our team is committed to the project through five years of monitoring, mapping, and reporting along with annual drone flights to demonstrate project success.

The Big Bend Mitigation Bank (BBMB) historically existed as BLH wetlands connected hydrologically with adjacent surrounding wetlands of similar habitat type. Prior to the construction of artificial drains, surface water was able to transfer via sheet flow to and from the site and adjacent properties. The BBMB will re-establish (155.4 acres) and rehabilitate (117.5 acres) 272.9 acres of BLH habitat that was converted agricultural fields in the 1970s. The total bank encompasses 303.9 acres with the excess being hydric inclusion (7.0 acres), non-hydric inclusion (16.9 acres) and non-hydric buffer (6.9 acres). The collective goal of the Bank is to provide restored and rehabilitated wetland habitat that can be used to replace the exact function and value of wetlands that are adversely affected by projects within the basin, in accordance with Section 404 of the Clean Water Act.

This 65-acre site is within a Wildlife Management Area (WMA) in the Green River Service Area, and the project is in support of the Kentucky Wetland and Stream In-Lieu-Fee (FILO) Program. The proposed restoration will re-establish two intermittent streams totaling 3,500 linear feet and re-establish 40.6 acres of bottomland hardwood forested wetland in Union County, Kentucky.

RES is providing stream restoration credits to Prince George’s County Maryland Clean Water Partnership (CWP) program. The CWP is a Public-Private Partnership formed to meet the US Environmental Protection Agency’s (EPA) Clean Water regulatory requirements. The projects delivered through this contract will be enrolled as part of Prince George’s County Bay TMDL Action Plan, with the associated nutrient reductions credited toward compliance with the Bay TMDL. The Black Swamp Creek Stream Restoration site restored 14,810 LF of degraded stream channel providing 296.21 Equivalent Impervious acre Credits to the CWP / Prince George’s County.  

To execute this project RES performed existing site assessments and geomorphic surveys. Using this data along with Natural Channel Design philosophies and published reference data RES designed bankfull channels that provided stable banks and frequent floodplain connectivity. RES designed full realignments of the streams to achieve proper stream sequencing and stable channel geometry. Additionally, RES ensured that there were no offsite floodplain rises and performed all necessary hydrologic and hydraulic modeling. RES acquired all state, federal and local permits necessary to execute the proposed work.  

Upon completion of the design and permitting, RES’ construction staff used a team of subcontractors and in-house construction crews to execute the project. Construction began in September 2020 and was substantially complete by March 2021. During construction, RES’ design staff remained an integral part of the team making frequent site visits, attending multiple site meetings, and ensuring the proper execution of the design.

RES was awarded the contract for the largest Permittee Responsible Mitigation (PRM) ecological mitigation project to date, to restore an approximately 17,000-acre area as part of the North Texas Municipal Lake Project.
The environmental mitigation is one important component of the North Texas Municipal Lake Project, an approximately 16,500-acre reservoir being built in Fannin County to provide critical new water services to the 13 cities in the District. RES will provide complete stewardship of the mitigation site, from design and implementation through monitoring and maintenance over the next 20+ years, in accordance with the environmental permit for the lake project. The permit requires that NTMWD offset the unavoidable environmental impacts of building the lake by restoring and permanently protecting wetlands, forests, grasslands, and streams at the mitigation site.
The mitigation plan encompasses over 6,800 acres of wetland restoration and enhancement on the Riverby Ranch in Fannin and Lamar Counties, which will provide wildlife habitat and improve water quality in North Texas and Oklahoma. As part of the project, RES will restore or enhance over 369,000 linear feet (70 miles) of streams and plant more than five million trees. In addition, RES will restore or enhance over 3,000 acres of native grasslands and over 2,600 acres of forests. RES will maintain full-time onsite staff living on the Riverby Ranch property as well as provide full project management of design, construction and monitoring of the site to ensure the restoration project is successful.

Established in 2011, the 327-acre site was previously deforested, converted to pasture, and used for grazing and hay production. RES restored the hydrology and ecological functions of the site to a contiguous, mature, hardwood flatwood conservation area.

The Bucher Mitigation project is in Durham County approximately seven miles northeast of Durham, NC in Neuse River HUC 03020201 within the Upper Falls Lake Watershed. This project provides a unique opportunity to protect 92.7 acres of riparian habitat (with the potential to protect an additional 5.9 acres in Phase II). The project will restore, enhance and preserve 17,628 linear feet of stream to generate stream credits and improve water quality, habitat, and hydrology within a water supply watershed. Water quality stressors currently affecting the Project streams include impoundment, historic forestry activities, floodplain disconnection and increasing impervious surfaces. Many of the project design goals and objectives will reduce future degradation of water quality and increases in nutrient inputs associated with anticipated suburban development. Construction began in May 2020.

The Buffalo Branch project is located within an agricultural watershed in Johnston County, North Carolina, approximately four miles North of Selma. The project involved the restoration and protection of streams in the Buffalo Creek watershed, with the overall goal of restoring and enhancing a stream/wetland complex located within the Neuse River Basin (below Falls Lake). Found within USGS HUC 03020201, a Targeted Local Watershed (TLW), the watershed is characterized by 44 percent agricultural land use area, and identified as a high priority watershed for projects that address flow restoration, reduction of impoundments, and buffer restoration. Before restoration and enhancement, the site consisted of cattle pastures and wooded areas, a mix of pines, hardwoods, and invasive species. Channels were severely degraded to a point where they no longer accessed their floodplain, lacked riparian buffers, allowed livestock access, and failed to support aquatic life. Our team’s work entailed the restoration of natural stream characteristics, such as stable cross sections, platform, and in-stream habitat. The floodplain areas were hydrologically reconnected to the channel to provide a natural exchange and storage during flooding events. In addition to the stream restoration, mitigation design preserved and enhanced the hydrology of six wetland seeps, two linear and four hillside, in the project area. Benefits of our efforts included stream banks erosion prevention and a reduction of in-stream sedimentation and nutrients, restoring the riparian buffer with native vegetation, ensuring hydraulic stability, and treating invasive species. The Buffalo Branch Stream Mitigation project is located in the southern portion of the TLW and includes streams that discharge into Buffalo Creek (303d listed). Due to its location and improvements, the project provided numerous ecological and water quality benefits within the TLW and Neuse River Basin.

Bunchs Creek Mitigation Bank will restore agricultural fields and cattle pasture to the bottomland hardwood and pine flatwood/savannah habitats that were on this 621-acre site in the 1920s. This bank will help RES clients in the Calcasieu Basin by providing cost-effective mitigation for their projects’ unavoidable wetland impacts. The site will also perpetually protect a nest location used by a pair of endangered whooping cranes that are part of the experimental population in Louisiana.

2019 Award Winner – Best Restored Beaches from the American Shore and Beach Preservation Association (ASBPA)

The Caminada Headland Beach and Dune Restoration Project is part of a restoration and protection of beach and dune habitat through the direct placement of approximately 5.4 million cubic yards of sandy material from Ship Shoal (an offshore borrow source). The fill material was barged to a staging area near the mouth of West Belle Pass, then pumped via a pipeline for placement on the shoreline.

This project created and enhanced over 300 acres of beach and dune, reinforcing almost six miles of barrier headland habitat, while reducing the impacts of storm events on Port Fourchon and LA Highway 1, a vital hurricane evacuation route for Fourchon and Grand Isle. The restoration project also provided important habitat for nesting shorebirds as well as migratory birds. RES’ role on this project was to install native species on the recently formed project features. Our nursery sourced seed stock from the USDA NRCS Plant Materials Center and had state plant material certification with the Louisiana Department of Agriculture and Forestry.

Under the State’s direction RES planted 75,970 four-inch containers of bitter panicum (Panicum amarum) and 30,338 one-gallon containers of sea oats (Uniola paniculate). Site conditions were loose sandy beach, where all mobilization was conducted via land-based routes.

Heat stress to plants was particularly a difficult obstacle for this project. Due to the heat, RES opted to perform multiple deliveries throughout the planting period bringing only enough plants that they could plant each day. Due to the adaptive planting techniques utilized by RES, this large-scale planting effort was very successful, and mortality of the newly planted vegetation was drastically reduced.

The Bank provides approximately 500 acres of bottomland hardwood and bald cypress-tupelo forest reestablishment to compensate for unavoidable wetland impacts in the Mermentau Basin.

The Carolina Heelsplitter Conservation Bank was the first aquatic species conservation bank in the Southeast. Due to the presence of a viable population, a low percentage of impervious surface, its location near a focus area for other conservation activities, and the potential to protect large portions of the watershed to have a positive impact, the Flat Creek watershed was chosen for the bank and conservation site. By preserving upland and riparian buffers, the Carolina Heelsplitter Conservation Bank ensures the protection of the endangered Carolina Heelsplitter Mussels’ habitat. The Carolina Heelsplitter Conservation Bank is certified to provide offsets as required under Lancaster County Zoning Ordinance #963 and is approved by the USFWS to offset direct and indirect impacts to the Carolina Heelsplitter Mussel in all of North and South Carolina.

The Casey-King wetland mitigation site of the Neu-Con Umbrella Mitigation Bank is located approximately five miles east of Kinston, North Carolina in Lenoir County and consists of an 86.7-acre property, of which 43.1 acres is under a permanent conservation easement. The targeted wetland system for the restored site was a “non-riverine, wet hardwood forest” with a small component of “coastal plain, small stream swamp” as described by Schafale and Weakley (1990). Site work including vegetation planting was completed March 2002. The project contains 37.3 acres of wetland restoration.

RES is currently performing stream, wetland, riparian buffer, and floodplain restoration on an agricultural site which drains into the Tridelphia Reservoir and Patuxent River in Howard County, MD, resulting in 4,200 linear feet of stream, 62 acres of impervious surface credit, and numerous acres of wetlands. This project will not only improve water quality in Cattail Creek through the restoration practices on the stream and wetlands, but also through the installation of Best Management Practices (BMPs) designed to capture stormwater runoff from the dairy and row crop operations. Restoration will be implemented in a fashion that will have minimal effect on current farming practices. The project provides additional educational opportunities related to environmental stewardship and agricultural sustainability for the Howard Soil Conservation District (HSCD) as the landowner already participates regularly with HSCD.

The Cedar Grove bank parcel is located within the Upper Falls Lake watershed in the Neuse River Basin (HUC 03020201). Prior to restoration, the site operated as a public golf course, with stormwater runoff draining into the East Fork Eno River. The restoration of this site improved and protected water quality within the Falls Lake watershed of the Neuse River Basin, by providing mitigation for unavoidable impacts from development. The mitigation was composed of stream restoration, riparian buffer, and nutrient offsets. Within the conservation easement, existing riparian areas were restored and enhanced to generate both buffer and nutrient offset (nitrogen and phosphorus) credits. In addition, the dimension, pattern, and profile of existing perennial and intermittent stream channels located within the conservation easement were restored at the site. Of the 63-acre conservation easement, approximately 43.74 acres are dedicated to Neuse buffer restoration/enhancement and nutrient offset-related restoration. A total of 15.19 acres of riparian buffer credits were generated. The remaining acreage of the riparian restoration area provided nitrogen and phosphorus offset credits within the Upper Falls Lake watershed.

The Center Bayou Mitigation Bank restores and protects approximately 1261.2 acres of bottomland hardwood (BLH) habitat, including 996 acres of agricultural land restored, 91.9 acres of BLH preservation, 35.4 acres of upland buffers, and 137.9 acres of non-mitigation features comprised of inclusions, upland buffer, existing structures, access roads, open water, and rights-of-way. An addendum was added to include the establishment and maintenance of approximately 1,151.90 acres of bottomland hardwood wetland habitat.

The goal of this 315.96-acre nutrient bank located in Campbell County is to reduce nutrient (phosphorus) and sediment loading into the Roanoke River watershed via the conversion of active agricultural land into forest; and generate non-point nutrient credits for transfer under existing and future federal, state and local law, programs, regulations and guidance. The site primarily consists of a mix of active agriculture and undeveloped forest. This site is within the twelve-digit hydrologic unit code (HUC) 030101011505 within the Roanoke River Basin. Specifically, the Roanoke River is the principle drainage for eight-digit HUC 03010101.

The Chewbacca Mitigation Bank is in McMinn County, Tennessee. The Bank will encompass approximately 148.3 acres within the Hiwassee (HUC 8 – 06020002) watershed. The project is also proposed to serve the Middle Tennessee-Chickamauga (HUC 8 – 06020001), and Watts Bar Lake watersheds (HUC 8 – 06010201) within the state of Tennessee. It will incorporate approximately 7,812 linear feet of intermittent and perennial stream channels.

The Chagrin River Watershed Partners (CRWP) and the City of Kirtland sought a qualified design-build contractor to complete the design and restoration construction of a streambank stabilization project along the East Branch Chagrin River. 

CRWP and the City applied for funding from the Ohio Environmental Protection Agency (Ohio EPA) Section 319(h) Nonpoint Source grant program to procure design-build services, in order to develop an innovative Natural Channel Design and streambank bioengineering approach to address significant channel impairments along the project reach.  

While the impetus for the project was the protection of Wisner Road and adjacent infrastructure from rapid bank erosion, our restoration design is multi-faceted and will reestablish equilibrium conditions that efficiently transport water and sediment, reverse systemic erosion, provide enhanced ecological value, restored in-stream habitat, and fisheries, and improved site aesthetics. RES achieved this with a combination of strategically placed in-stream structures and innovative bioengineered bank treatments that replicate the natural stabilization processes in order to regain channel stability and restore the lost functions and values of a robust stream system.  

Our approach relied on rebuilding the toe of the slope, prior to grading eroded banks back to a stable angle of repose. Bank reinforcement included the application of composite revetment, a layered bioengineered bank treatment of rock, geotextile, soil, and live woody cuttings. RES constructed the composite revetment in combination with two rock riffles to strategically direct flow, narrow and deepen the existing channel, and establish stable meander geometry. These structures act as a catalyst for deep center channel development, provide a localized reduction in shear stress, and lead to the development of stable streambanks, pool/riffle habitat, diverse bedforms, and in-stream habitat. Along an adjacent meander bend, a flood bench was reconstructed, using a combination of materials salvaged on-site. These materials included on-site rock and riprap, stream gravel, large timber, and woody debris to create a natural toe-of-slope treatment, called toewood revetment. Toewood revetment mimics the natural recovery processes in riverine systems and provides prime resting and feeding habitats for Salmonids. RES designed, permitted, and constructed the project, completed in June of 2020. 

RES was contracted to provide engineering services in support of the Clarksville Town Hall Stormwater Basins in Clark County, Indiana.  The project site includes two stormwater basins along the west and north sides of the site.

The Cline Run Mitigation Bank is located on 372.72 acres, on multiple parcels of land. The goal of this site is to restore hydrology, hydraulic and geomorphic functions to stream and riparian ecosystems within the site boundary, yielding 22,210 steam credits and 1.74 wetland credits.

This bank is the first wetland/stream mitigation bank in south-central Pennsylvania. Wetland and stream credits from this bank satisfy mitigation requirements in the PA State Waterplan Subbasin #7 (Lower Susquehanna Subbasin) including most of Lancaster, York, Lebanon, Dauphin, Cumberland counties, and portions of Chester, Perry, Franklin Berks, and Adams counties. This site will restore/rehabilitate/enhance 11,466 linear feet of stream channel and 1.63 acres of wetlands on a 51-acre site.

Established in 2017, the goal of Columbia Bottomlands Mitigation Bank is to provide appropriate compensatory mitigation for unavoidable impacts to wetlands authorized by the USACE within the Brazos/Oyster Creek watershed and adjacent areas. The objectives of the Bank are to rehabilitate degraded functions to 8.04 acres of existing jurisdictional wetlands, re-establish and sustain wetland functions to 323.9 acres as bottomland hardwoods wetlands, and re-establish and sustain wetland functions to 21.6 acres as coastal prairie emergent wetlands.

The goal of the Comite Mitigation Bank was to re-establish, rehabilitate, and enhance the area as sustainable forested, hardwood, wetland ecosystems for compensatory mitigation purposes. The Bank increases the quality of the forested wetland habitat for resident and migratory wildlife and restores agricultural lands to a natural ecosystem. The Bank helps to reduce flooding and point source pollution within the Lake Pontchartrain Basin.

The project consisted of restoring two degraded intermittent stream channels in Community Center Park, which is a public park owned and operated by the City of St. Matthews (City) in Jefferson County, KY. The main intermittent channel was approximately 1,800 feet long, while its unnamed intermittent tributary was approximately 700 feet long.

The Compass Point Mitigation site is located in Yadkin County, approximately 4.5 miles northeast of Boonville. The project presents 5,304 linear feet (LF) of stream restoration and enhancement generating cool stream mitigation Units (SMU) along three unnamed tributaries that drain directly to the Yadkin River within Cataloging Unit 03040101, 12-digit United States Geological Survey (USGS) HUC 030401011001, and North Carolina Department of Water Resources (NCDWR) sub-basin 03-07-02. The current State classification for the Yadkin River at this location is Class C (NCDWQ 2011).

The project’s total easement area is approximately 165 acres within the overall drainage area of 271 acres. Water quality stressors currently affecting the Project include livestock production, agricultural production, and lack of riparian buffer. Grazing livestock have historically had access to most stream reaches within the Project. The lack of riparian buffer vegetation, deep-rooted vegetation, and unstable channel characteristics have contributed to the degradation of stream banks throughout the project area.

The project provides numerous ecological and water quality benefits within the Yadkin River Basin by applying an ecosystem restoration approach. The restoration approach at the reach scale of this project will have the greatest effect on the hydraulic and geomorphology function of the system but will benefit the upper-level functions (physiochemical and biology) over time, and in combination with other projects within the watershed. Buffer improvements filter runoff from agricultural fields, thereby reducing nutrient and sediment loads to the channel. Livestock exclusion fence was installed along the easement boundary. The widening and restoration of the riparian areas will also provide wildlife corridors throughout the Project area. Benefits to be accrued from these activities include improved water quality and terrestrial and aquatic habitat. Stream construction was completed in May 2020.

The Dairyland Stream Mitigation site is located in Orange County, North Carolina, about eight miles southwest of Hillsborough. Dairyland is within the Haw River portion of the Jordan Lake Watershed, 03030002 HUC, which is highly developed along the I-40 Corridor from Greensboro to Chapel Hill, and is dominated by agricultural and forested areas south and north of the I-40 Corridor.

Pre-restoration, the project area exhibited diminished hydrology and habitat value as a result of past agricultural activities. The project watershed is primarily characterized by agriculture, forests, and low-intensity residential areas. Land use at the site is characterized by the row crop production, pasture, impoundments, and disturbed forest. Pre-restoration, riparian zones were primarily composed of herbaceous vegetation and scattered trees located adjacent to the streams. The project area contains two parcels totaling 28.6 acres of conservation easement in the southwestern Orange County, NC. Hudson Branch (HB-1 and HB-2) and two unnamed tributaries (including two ponds) encompass the majority of the northern part of the project area.

RES was awarded a Greened Acre Retrofit Program (GARP) grant to implement the Darien Crossing Regional Stormwater Retrofit on a parcel owned by the Philadelphia Industrial Development Corporation (PIDC). The GARP program is a component of the Philadelphia Water Department’s (PWD) innovative Green City, Clean Waters Program, which was adopted in 2011 as Philadelphia’s plan to reduce stormwater pollution currently entering its combined sewer system using green infrastructure. This project, located near the very active stadium district in South Philadelphia, provides PWD a large-scale green stormwater project at a high-profile, highly visible, impervious-dominated part of the City. It provides a unique opportunity for RES to develop an innovative solution that addressed PWD’s programmatic goals while maintaining the preferred land use of PIDC and the surrounding stakeholders.

The project includes the demolition of a vacant portion of an existing warehouse (while maintaining the remainder of the building’s tenants), installation of underground stormwater detention facilities, which will capture and store combined sewer overflows (CSO’s) before they reach the PWD system. The system will be capped with new parking and landscaping, which will be used by visitors to both Lincoln Financial Field and Citizens Bank Park.

Additionally, RES executed a long-term lease agreement with PIDC to operate and maintain the facility for a 45-year period post-construction. PIDC and other stakeholders will benefit from reduced stormwater fees after implementation of the project.

Through its on-call contract with Montgomery County, MD, RES provided construction services to create a series of 10 road side basins/cells designed to collect and filter roadside run-off before being discharged into Sligo Creek. Several of the basins/cells were constructed on Maryland National Capital Parks and Planning Commission (MNCPPC) park property, while others were constructed along the road and in the right of way between the sidewalk and curb, or within the roadway (curb bump outs). The project was designed so that run-off to each of these basins is conveyed through a series of modified storm drain inlets draining directly into each respective basin. Once the stormwater is collected in each basin, it filters through several layers of filter media (mulch, bioretention soil, and stone) and is collected in an underdrain system connecting each of the basins to the existing stormwater infrastructure. Each basin was planted with a variety of native grasses and shrubs. This project combined Infiltration and Filtering Practices, as classified by MDE’s Stormwater Design manual.

The goal of the project was to transform what was most recently drained agricultural land back into functional wetlands supported by restored streams. RES performed restoration services to 1,381 LF of its waterways and created 60.6 acres of wetlands on the Irvine Nature Center premises. The project was constructed in four phases.

1. In the Eastern Phase RES installed one wetland and restored 594 LF of stream.
2. In the Northern Phase RES installed three wetlands and restored 419 LF of stream.
3. In the Western Phase RES restored 434 LF of stream.
4. In the Central Phase RES installed one wetland and restored 34 LF of stream.

A series of mulch access roads were installed to allow access to each of the phases and were dismantled upon completion. Erosion and Sediments Controls consisted of hardwood matting, temporary bridges, filter log, silt fence, and super silt fence. Pump around systems were installed, as needed, and dismantled per the plans with each phase. Three boulder grade control structures, two downed log structures, 273 LF of riffle, 100 LF of floodplain riffle, and 77 LF of cascade were installed. RES installed approximately 2,000 LF of berm which aided in the creation of the 60.6 acres of wetland. The site was stabilized with hardwood mulch and coir matting.

RES and Biohabitats were committed to implementing creative and environmentally friendly practices throughout this project. To minimize the import of outside materials, dirt generated from the grading efforts of the wetlands was utilized to construct the berms. The berms themselves serve twofold, aiding in the wetland creation while also adding to the Nature Center’s already extensive network of trail systems. RES was allowed to incorporate any cleared trees into the pools of the wetlands to serve as habitat structures. Wood chips that were brought into the site for the mulch access roads were dismantled and reused as the required sediment control to cover all disturbed and graded areas. Planting of the site was completed in Fall 2017 and consisted of 2,183 trees and shrubs.

The Ivey Ferguson site is located within the Upper New Hope Arm of the B. Everett Jordan Lake watershed in Orange County. Stormwater run-off from this site drained into an unnamed tributary of Phils Creek which in turn emptied into University Lake approximately 3.4 miles downstream. Through about 12-acres of a re-forested buffer area, this bank site produced water quality improvements within the watershed. RES planted trees to provide run-off filtration and nutrient uptake along 2,700 linear feet of channel. Due to its location within the sub-watershed, the Ivey Ferguson Bank Parcel has a 40% delivery factor for nitrogen removal and a 19% delivery factor for phosphorus removal.

The Jack Smith Creek Stormwater Wetlands (JSCSW) project was a partnership between the City of New Bern, North Carolina State University (NCSU), North Carolina Ecosystem Enhancement Program (NCEEP), and the North Carolina Clean Water Management Trust Fund. RES (formerly Carolina Environmental Contracting prior to 2020 acquisition by RES) was selected to construct a stormwater wetland that currently captures and treats runoff from more than 1,000 acres of both residential and commercial properties in New Bern. This project was significant due to not only the volume of stormwater that it can now accommodate but because it is the largest manmade wetland constructed in the state of North Carolina. 

The design of the JSCSW incorporated a multi-cell treatment approach that moves the water through various cells, adjustable weirs and culverts to maximize water quality improvements as these best management practices (BMPs) remove contaminants while the stormwater travels through the various systems. Each cell was constructed differently to maintain various depths and velocities. These differences among the cells will maximize the diversity in the wetland community to encourage a varied habitat for the better long-term viability of both flora and fauna. 

The project consisted of 25 acres of constructed wetlands, more than 10 acres of preserved wetlands, and 2.3 acres of enhanced wetlands. Over 7,000 of the stream was incorporated into the wetland cells. Work included clearing, grubbing, and grading the wetlands. Nine culverts were installed, three with flap gates. Two concrete water control systems, one vinyl sheet pile weir, rock spreaders, and inlet and outlet pools were included in the design to maintain grade control. A permanent maintenance road was constructed and a pump berm was incorporated in the design to assist with the magnitude of high stormwater flow. 

Over 150,000 native wetland plants, trees and shrubs were planted upon completion of construction that will act as filtering components and also will provide extensive habitat for fish and wildlife.  

This large-scale project was the first of its kind in the state due to the unique nature of the project, the partnership with NCSU and NCEEP, the management of the project, the high visibility of the project due to its innovation, and the large quantity of clearing and grading.

The Louisiana Children’s Museum is relocating in 2019 to a larger site in City Park that includes a wetlands feature and a series of associated educational opportunities. To support the museum in its mission, RES donated more than 6,000 plants and provided labor and volunteer coordination for their planting in May of 2018.

The plants were provided by RES’ nearby nursery in Pointe Aux Chenes, Louisiana, and included more than 15 varieties of marsh grasses and bushes. RES’ donation included the plantings, several days of planting labor, and will be working with the museum staff over the next three years to properly maintain these features on the property.

The Maple View Bank Site is located within the Upper New Hope Arm of the B. Everett Jordan Lake watershed. This section of Morgan Creek and two unnamed tributaries traversed the site and exhibited diminished habitat value as a result of past and ongoing agricultural activities and impervious watershed conditions. This bank site provides water quality improvements within the watershed through approximately 7.63 acres of re-forested buffer area. RES planted trees, providing run-off filtration and nutrient uptake along 2,000 linear feet of channel. Due to its location within the sub-watershed, the Maple View bank parcel has an 89% delivery factor for nitrogen removal and a 71% delivery factor for phosphorus removal.

Beginning in 2018, RES provided full delivery stream restoration services along Mardella Branch in Baltimore County, MD. This project is one of six that RES implemented under Maryland State Highway Administration’s Full Delivery Stream Restoration Services contract to help meet SHA’s total daily maximum load (TMDL) requirements.

The project was broken down into two distinct reaches (North and South) divided by Offutt Road and totaling 2,881 LF. This project was designed utilizing a Natural Channel Design (NCD) approach while also facilitating more frequent floodplain access during high-flow events. In addition to substantial nutrient pollution reduction, the Mardella Branch restoration generated co-benefits including greater floodplain reconnection, wetland generation, and habitat and biodiversity recruitment post-construction. RES’ responsibility included site selection and coordination with private landowners, design, permitting, construction, and long-term monitoring.

During construction RES utilized mulch and deckmat access roads to limit overall ground disturbance and over compaction of subsoils. Having been involved in the site development allowed for a high-use of site-generated materials; all of the trees that were removed for construction were utilized in the creation of stream structures and additional access paths, and the existing streambed material was utilized in the stream pool and riffle areas. Instream structures and features that were implemented included imbricated toe protection, log sills, log drops, toe wood, live lifts, riffle and pool combinations, and the creation of oxbow wetland within portions of the abandoned stream channel.

The Mardella Branch watershed continues to be rapidly developing with yearly increases in the overall impervious area upstream of this site; the implementation of the RES approach will result in the reduction of 392 pounds of phosphorus, 851 pounds of nitrogen, and 68 pounds of sediment per year for this watershed.

This project required close coordination with several interested project participants and entities including the property owners, SHA, Baltimore County, Maryland Department of the Environment (MDE), the US Army Corps of Engineers (USACE), and various subcontractors and suppliers. As this stream has a Use III designation and closure period from October 1 through April 30, RES’ coordination and logistics among the project participants allowed for successful and on-time delivery.

The Marston riparian wetland mitigation site is located in Jones County, approximately twelve miles west of Trenton, North Carolina. Ditches on the site were used to promote drainage when the land was under agricultural production. This project restored the main channel, a smaller tributary, and approximately 37 acres of on-site wetlands for the purpose of wetland and stream mitigation. In addition, the site provides riparian buffer restoration and nutrient offset credits. The Marston project restored a “Coastal Plain small stream swamp” and associated buffer area.

In 2017, the Maryland Department of Transportation, State Highway Administration (SHA) selected RES to perform Full Delivery Stream Restoration Services on multiple sites throughout the state. Under this contract, RES fully delivered more than 22,000 linear feet of stream restoration at 6 private land sites throughout the state. For each project, RES was responsible for site selection, land acquisition, survey, design, permitting, construction, monitoring, and adaptive management to support the SHA’s Chesapeake Bay restoration goals. RES’ six projects were located in Anne Arundel, Baltimore, and Frederick Counties.

Exemplary of RES’ design and construction versatility, site-specific restoration approaches were determined by each site’s conditions and implementation feasibility. Across the six projects, RES designed and constructed projects utilizing Natural Channel Design and Integrated Floodplain Wetland approaches, as well as hybrid approaches utilizing techniques from both NCD and IFW, determined on a site-by-site basis.

Site design is a team effort, with designs provided by RES’ in-house stream designers and engineers as well as from staff of our partner firms. This collaborative team provided oversight during construction to ensure project components were built according to approved plans.

Stream construction tasks consisted of mobilization, erosion and sediment control installation, clearing and grubbing, maintenance of streamflow, rock/log structure installation, riffle grade control installation, bank stabilization matting, seeding, and planting.

Projects implemented under this contract include:

• Bens Branch – Frederick Co. – 4,877 linear feet
• Mardella Branch – Baltimore Co. – 2,881 linear feet
• Tarnans Branch – Anne Arundel Co. – 4,421 linear feet
• UT to Broad Run – Frederick Co. – 5,325 linear feet
• UT to Patapsco Creek – Baltimore Co. – 1,462 linear feet
• UT to Talbot Branch – Frederick Co. – 3,132 linear feet

This Permittee-Responsible Mitigation (PRM) project was designed to mitigate for a new pipeline with unavoidable impacts to 450 acres of wetlands in Eastern Louisiana, within a Wildlife Management Area managed by Louisiana Department of Wildlife and Fisheries. Restoration of the PRM tracts, contained entirely within the Maurepas Swamp, was coordinated to support proposed freshwater introductions sponsored by various state and federal agencies.

The Maurepas Swamp has been in a steady state of decline since the 1920’s and 1930’s when most of the area was heavily logged for cypress timber. The implementation of diversions and facilitated drainage had increased stagnation of the swamp areas within the Lake Maurepas basin. The lack of freshwater inflow over time has gradually decreased the nutrient load and hampered the growth of forested habitats.

The PRM project sites are in areas that were historically composed of primarily old growth cypress-tupelo swamps with some hardwood component on the ridges of the interior. Restoration and preservation under the PRM covered enhancing 485 acres of bottomland hardwood habitat and 67 acres of cypress/tupelo swamp, and rehabilitating 85 acres of cypress/tupelo swamp. These activities were coordinated with a number of stakeholders, including the ESACE New Orleans District and Louisiana Department of Natural Resources Office of Coastal Management, to best support the landscape-scape restoration goals for the swamp, and included a donation of land by RES of 7,039 acres of forested wetlands to Louisiana Department of Wildlife and Fisheries for inclusion within the Maurepas Swamp Wildlife Management Area.

The Meadow Spring mitigation site is located three miles north of Smithfield and contains three parcels totaling 246-acres in Johnston County. The Site involved the restoration and enhancement of streams and wetland along an unnamed tributary to the Neuse River. The site is located within the Neuse River Basin, below Falls Lake, USGS HUC 03020201 and in the Meadow Spring Creek Watershed, a Targeted Local Watershed (TLW). RES’ efforts resulted in significant ecological improvements including water quality improvement, habitat restoration, and a decrease in non-point source pollution from stormwater and agricultural practices. Our design addressed degraded water quality and nutrient input from farming, items previously identified as major watershed stressors in the 2010 Neuse RBRP. These issues were combated with the restoration of riparian buffers to filter runoff from agricultural operations and improve terrestrial habitat, and through the construction of in-stream structures to improve habitat diversity. In addition to the stream restoration, the site provides nutrient offset mitigation and riparian buffer mitigation through the NC Division of Water Resources (DWR) Neuse Riparian Buffer Mitigation program. The buffer and nutrient offset mitigation were developed through a separate banking instrument.

The goal of this 28.0 acre Nutrient Bank located in Northampton County, Virginia is to reduce nutrient (phosphorus) and sediment loading into the Mid-Atlantic Coastal Watershed via the conversion of active agricultural land into forest; and generate nonpoint nutrient credits for transfer under existing and future federal, state and local law, programs, regulations and guidance. The site primarily consists of crop production.

The goal of this 35.54 acre nutrient bank located in Northumberland County is to reduce nutrient (phosphorus) and sediment loading into the Potomac River Watershed via the conversion of active agricultural land into forest; and generate non-point nutrient credits for transfer under existing and future federal, state and local law, programs, regulations and guidance. The site primarily consists of a hayfield. The land-use conversion will generate 164.91 pounds of nitrogen reduction and 24.17 pounds of phosphorus reduction.

The bank’s restoration objective was to restore approximately 435 acres of wet longleaf pine savannah and 160 acres of wet slash pine-pond cypress woodlands; rehabilitate approximately 651 acres of wet longleaf pine savannah and 361 acres of wet slash pine-pond cypress woodlands; restore/rehabilitate 23 acres of mixed bedded and non-bedded longleaf pine savannah; restore/rehabilitate 287.2 acres of longleaf pine flatwoods as upland buffers/inclusions; and enhance 369 acres of bayhead swamp.

The Mud Creek Stream Mitigation Bank site is in east central Tennessee, approximately 27 miles northeast of Crossville in the central part of Morgan County in the town of Wartburg. The site has one main access point located on the northern side of Letory Road (36.107390, -84.571612). Approximately 34 acres of this property is located within the HUC-12 Middle Emory River watershed and the remainder of the property, approximately 914 acres, is located within the HUC-12 Crooked Fork watershed. These watersheds are both located within the HUC-8 Emory River watershed, which is within the Upper Tennessee basin and falls on the line of the Level III eco-regions 68 (Southwestern Appalachians) and 69 (Central Appalachians). The site will incorporate approximately 6.9 miles (36,234 LF) of headwater intermittent and perennial stream channels along the main channel and several unnamed tributaries to Mud Creek.

The Nahunta Swamp riparian mitigation site is located in Wayne County, North Carolina approximately eight miles northeast of Goldsboro. All project properties are located adjacent to Nahunta Swamp. The entire project site is approximately 249 acres in size, with approximately 126 acres of prior-converted cropland. The Nahunta project restored “Coastal Plain small stream swamp,” and “non-riverine hardwood forest” communities. Stream and wetland restoration involved raising the bottom elevation and re-establishing a normal pattern on six of the tributaries draining into Nahunta Swamp. These measures raised the local water table and restored wetland and stream hydrology on the mitigation site. Riparian buffer restoration included restoring a hardwood forest community. The entire mitigation area is protected with a permanent conservation easement. The mitigation practices have resulted in approximately 33.5 acres of riparian buffer restoration and 164,158 pounds of nitrogen offset credit.

This project, for the North Carolina Department of Transportation(DOT) and the Department of Mitigation Services (DMS), is for delivery of water credits. The project covers delivery of ecological restoration credits for NCDOT and DMS in the form of 35+ full delivery/turnkey projects, generating $70 million worth of water quality improvements . It is comprised of 270+ riparian acres generating 260+ credits, 170+ non-riparian acres generating 100+ credits, 284,000+ lf of stream generating 227,000+ credits , and 65 acres of buffer.

In 2012, Anne Arundel County Department of Public Works (DPW) contracted RES’ Angler Construction division to restore approximately 3,000 linear feet of main-stem stream, 900 linear feet of tributary drainages and seven acres of wetlands on the North Branch of Cypress Creek. The restoration utilized many techniques to manage the stormwater discharge in the main channel and its tributaries while creating floodplain wetlands that transition to tidal waters and removing significant pollutant load from the upstream impervious area.

The project design created an open water and shallow wetland feature to attenuate stormwater flows and reduce peak discharges through the system. Additionally, regenerative stormwater conveyances were installed to convey flow from road-based culverts. The main channel was restored to flow out of the headwater wetland into a single thread channel that conveys flow through rock and log step pools into an anastomosed or DA-type channel, which is a stream with multiple channels and islands. The middle reaches along the North Branch were excavated and filled to create floodplain wetlands. Old dam embankments were lowered, repaired, and graded to impound shallow water in the wetlands. The transition from the floodplain wetlands to the tidal channel section was reconstructed as an E-type channel to provide a gradual riffle that reconnected the tidal channel to its floodplain. This riffle allows for fish passage from the tidal area into the floodplain wetland impoundments and as far upstream as the headwater wetland.

Structures installed by RES included:

• Fifteen cobble weirs
• Fifteen sandstone outfalls 
• Six floodplain grade control structures (cobble/sandstone mix)
• Four log grade control structures
• Nine boulder cobble cascades
• Six log/ boulder step-pools

Over 25,000 native plants added to the habitat creation throughout the project site. A diversity of plant species was used to create both upland and wetland habitat.

RES was an active team member for the Parklands of Floyds Fork Project in Louisville, Kentucky.  The purpose of the project was to establish a greenway along the perennial stream Floyds Fork in eastern Jefferson County, Kentucky that would consist of a network of trails, roads, parks, and associated amenities along approximately 3,200 acres and distributed over 19 miles.

The Bank provides 187.5 acres of BLH to compensate for unavoidable wetland impacts for the Vermilion-Teche Basin.

The Pennsylvania Statewide Bat Conservation Bank is the first U.S. Fish & Wildlife Service (USFWS)-approved species Conservation Bank of its kind in Pennsylvania. Over the course of three years, RES collaborated with the USFWS Pennsylvania field office to select a site, develop a crediting methodology, and finalize the first endangered species conservation banking instrument in the State. The purpose of the Pennsylvania Statewide Bat Conservation Bank (Bank) is to provide and protect high-quality self-sustaining bat habitat to offset statewide impacts to the federally listed Indiana bat (Myotis sodalis) and its habitat. This objective supports the Endangered Species Act of 1973 (87 Stat. 884, as amended; 16 U.S.C. 1531 et seq.), which was enacted to ensure the protection of endangered species such as the Indiana bat. This objective is also consistent with the policies described in the U.S. Fish and Wildlife Service Mitigation Policy (46 FR 7644-7663, January 23, 1981) and Guidance for the Establishment, Use, and Operation of Conservation Banks (68 FR 24753, May 8, 2003). Conservation banking creates a collaborative incentive-based approach where habitat for listed species is treated as an asset rather than a liability.

By permanently protecting high-quality forested habitat in a critical Indiana bat habitat zone, the Pennsylvania Statewide Bat Conservation Bank provides an advance compensatory mitigation mechanism to support the Endangered Species Act and the relevant federal mitigation initiatives. The Bank is located within the known range of the Indiana bat and includes more than 438 contiguous acres of high-quality habitat used by two Indiana bat maternity colonies. Although Indiana bats have experienced significant population declines due to a malady known as white-nose syndrome, the Indiana bat maternity areas in Washington and Greene Counties persist. The maternity area includes three partially conjoined maternity colonies consisting of primary and alternate roost trees and the surrounding 2.5-3-mile foraging habitat (USFWS 2016).

In addition to providing extremely high-quality bat habitat, the Pennsylvania Statewide Bat Conservation Bank site abuts two known Biodiversity areas identified by the Pennsylvania Department of Conservation and Natural Resources and hosts the Mixed-Mesophysic Forest Target Plant Community, an extremely rich terrestrial community type on deep soils in protected concave coves or lower slopes only in Greene County, PA. The Site also includes the known range of one endangered plant (Nuttall’s Hedge-nettle, Stachys cordata) and four special concern plant species (Single-headed Pussy-toes (Antennaria solitaria), American Beakgrain (Diarrhena americana), and Leaf-cup (Smallanthus uvedalius).

The goal of the Bank was to re-establish and rehabilitate sustainable bottomland hardwood and bald cypress forested wetland ecosystems for compensatory mitigation purposes. The re-establishment and rehabilitation of bottomland hardwood and bald cypress wetland ecosystems was accomplished by converting existing agricultural and pasture and Chinese tallow (Triadica sebifera) forests to a natural species composition indicative of a bottomland hardwood and bald cypress wetland forest and subsequently, increasing wetland functions, values, and services.

This site is providing mitigation credits from the restoration, preservation, and enhancement of 70,115 linear feet of streams and the preservation and restoration of 359 acres of riparian buffers within Buckingham and Albemarle Counties. The Piedmont Farms Bank is made up of two individual bank sites: Eastview Farms and Fulfillment Farms Bank Sites.

The goal of this 216.04 acre nutrient bank located in Suffolk County, Virginia is to reduce nutrient (phosphorus) and sediment loading into watersheds via tributaries located within and/or in close proximity to the Bank through the conversion of active agricultural land into forest; and generate certified non-point nutrient credits for transfer under existing and future federal, state and local law, programs, regulations and guidance, including the DEQ Guidance.

The bank established approximately 240.50 acres of bottomland hardwood wetland habitat.

Pleasant Run Creek (PRC) is an urban stream with an approximately 12.4-square mile (1,135-acre) watershed that bisects an 87-acre former Manufactured Gas Plant (MGP) within Indianapolis, Indiana.

The Polecat mitigation site is located within a watershed dominated by agricultural land use in Johnston County, North Carolina, approximately two miles southeast of Smithfield. The project streams have been significantly impacted by livestock access, row crop production, and nearby urbanization. The project will involve the restoration and protection of streams in the Neuse River watershed on approximately 53 acres of conservation easement. The purpose of this mitigation site is to restore and enhance a stream complex located within the Neuse River Basin. The site supports many of the Neuse River Basin Restoration Priorities Pan (RBRP) and Neuse Regional Watershed Plan (RWP) goals. The project’s watershed is primarily rural with Interstate 95 occupying the western portion of the watershed. The project parcels have been in agricultural use for several decades.

The site includes streams that directly discharge into the Neuse River. Many of the project design goals and objectives, including restoration of riparian buffers to filter runoff from agricultural operations and improve terrestrial habitat, and construction of in-stream structures to improve habitat diversity, will address the degraded water quality and nutrient input from farming that were identified as major watershed stressors in the 2010 Neuse RBRP. Water quality stressors affecting the site include livestock access, row crop production, and impervious surface. The project presents 8,178 linear feet of stream restoration and enhancement generating 6,567 Stream Mitigation Units (SMU).

The Poplar Creek project is located in Johnston County, approximately three miles north of Smithfield within the Neuse River Basin HUC 03020201. Water quality stressors affecting the project area included livestock production, agricultural production, closed drainage system, and an impoundment. Goals for the project include an increase to hydrologic function and restoration to ecological function within the existing stream and riparian corridor, and the protection of these features in perpetuity. These were accomplished by removing an agricultural impoundment, planting the riparian buffer, excluding livestock from the conservation easement through fencing, and returning the existing streams to stable conditions by constructing a stream channel with appropriate dimensions and pattern and reconnecting the channel to the floodplain. The project presents 4,273 linear feet of stream restoration and enhancement, generating 3,926 Stream Mitigation Units along three unnamed tributaries that drain into Poplar Creek. The Poplar Creek project also generates approximately 93,766 SF of riparian buffer restoration credits, 76,454. SF of riparian buffer enhancement credits via cattle exclusion, 8,220.5 SF of riparian buffer preservation credits, and 1,454.73 lbs of nitrogen credits. Construction was completed in 2019

The Scout Mitigation project is located within an agricultural watershed in Davie County, approximately eight miles west of Clemmons and five miles northwest of Bermuda Run within Yadkin River HUC 03040101, in TLW 03040101160010. The project area is comprised of a single easement located along Hauser Creek and two unnamed tributaries. The project is located between two sections of the overall 27-acre DMS Mockingbird site, and upstream of the closed out DMS UT to Hauser Creek project. The DMS Catbird site is in an adjacent catchment to the east. The streams proposed for restoration have been historically impacted by livestock production, agricultural practices, and a lack of riparian buffer.

Goals for the project include an increase to hydrologic function and restoration to ecological function within the existing stream and riparian corridor and protecting these features in perpetuity. These will be accomplished by returning the existing streams to stable conditions by constructing an E/C type stream with appropriate dimensions and pattern, reconnecting Hauser Creek to the floodplain, and backfilling the abandoned channel. In-stream structures will be installed for vertical stability and to improve habitat, where necessary. Buffer improvements will filter runoff from the surrounding pasture lands. The project presents 3,144 LF of stream restoration and enhancement, generating 2,918 Warm SMUs. Construction was completed in May 2020.

The site primarily consists of: approximately 146.33 +/- acres of agricultural land in hay production and 26.27 +/- acres of row crop with the remainder in forest or other non-agricultural use. This site is within the twelve-digit hydrologic unit code (HUC) 030101040304. Specifically, the site drains to the Dan River, the Dan River is the principle drainage for eight-digit HUC 03010104.

The Selma Mill riparian buffer and nutrient bank’s service area is Hydrologic Unit Code (HUC) 03020201 of the Neuse River watershed, below Falls Lake. Before restoration, agricultural impacts were prevalent, including nonpoint source runoff and hydrologic modification. Priority projects for this watershed included projects that promoted nutrient and sediment reduction, as well as focusing restoration on achieving the most functional improvement to the ecosystem possible. A secondary priority concentrated on developing projects that reestablish riparian buffers and corridors of substantial width to improve connectivity to larger intact conservation areas. The Selma Mill Buffer and Nutrient Offset Site is located in southeast Johnston County, NC, immediately north of Selma. The site easement includes three unnamed tributaries and stormwater runoff from adjacent pastures that flow directly to Mill Creek. A majority of the site was previously used for livestock grazing, pasture, and row-crop production. Restoration of the riparian buffer resulted in immediate water quality benefits within the vicinity of the site through the removal of livestock access to site streams. The riparian restoration activities on the site also resulted in improved water quality to the downstream watershed.

The stream mitigation bank encompasses 59.2 acres across three adjoining tracts located near Allisona, Williamson County. The mitigation project restores approximately 3.29 miles (± 17,359 linear feet) of ephemeral, intermittent and perennial stream channels in Overall Creek, North Fork Flat Creek, and West Fork Spring Creek watersheds, which are tributaries of the Harpeth River, which ultimately drains into the Cumberland River. This bank provides compensatory stream mitigation for permitted impacts within the proposed geographic service area of the Harpeth (05130204), Lower Cumberland- Sycamore (05130202), and Stones (05130203) HUC 8 watersheds.

The Seven Pines Mitigation Bank is located on eight parcels of land, all held by various landowners, which total approximately 384-acres. The goal of the bank is to restore, enhance and preserve self-sustaining, functional streams and wetlands to mitigate for lost functions due to unavoidable off-site impacts to streams and wetlands. This project will restore hydrology, hydraulic and geomorphic functions to stream and riparian ecosystems within the site boundary and produce 11,602 stream credits and 3.81 wetland credits.

The Stone Creek mitigation site is located approximately 14 miles southeast of Smithfield and contains three parcels totaling 161-acres in Johnston County, NC. The site involves the restoration and enhancement of unnamed tributaries to Mill Creek. The site was identified by RES as having potential to help meet the compensatory mitigation requirements for stream impacts in hydrologic unit 03020201 of the Neuse River Basin.

This proposed site will result in significant ecological improvements including water quality improvement, habitat restoration and a decrease in non-point source pollution from stormwater and agricultural practices. The site is located in the Mill Creek Watershed, a Targeted Local Watershed (TLW)  and supports many of the Neuse River Basin Restoration Priorities Plan (RBRP) and Neuse Regional Watershed Plan (RWP) goals.

Many of the project design goals and objectives, including restoration of riparian buffers to filter runoff from agricultural operations and improve terrestrial habitat, and construction of in-stream structures to improve habitat diversity, will address the degraded water quality and nutrient input from farming that were identified as major watershed stressors in the 2010 Neuse RBRP.

The conceptual design presents 5,886 linear feet of stream mitigation generating 4,547 Stream Mitigation Units (SMU). In addition to the stream restoration, the site could potentially provide nutrient offset mitigation and riparian buffer mitigation through the NC Division of Water Resources (DWR) Neuse Riparian Buffer Mitigation program. The buffer and nutrient offset mitigation will be developed through a separate banking instrument.

RES is working with Anne Arundel County to provide cost-effective pollutant (i.e. nitrogen, phosphorus, sediment) reductions and equivalent “impervious acres treated” on private lands throughout the County. These projects include outfall stabilization, and wet and dry pond retrofits, and continuous monitoring on four sites. In total, these projects will produce an estimated 188.6 Impervious Acre Credits for the County. Our external partners provide stormwater retrofit engineering and Municipal Separate Sewer (MS4) support services, as well as a cloud-based platform to monitor and control stormwater facilities. The technology, known as Continuous Monitoring and Adaptive Control (CMAC), uses data from on-site sensors, weather forecasts, and site-specific parameters to make intelligent and predictive control decisions about when water is discharged from stormwater facilities.

In 2020, RES completed stream restoration design and construction services along Tarnans Branch in Anne Arundel County, MD. This project was submitted as part of the 2017 Maryland State Highway Administration (SHA) Full Delivery Stream Restoration Services RFP, to help meet SHA’s total daily maximum load (TMDL) requirements.  

The project required the restoration and stabilization of 4,421 LF of a degraded and unstable stream channel as well as the restoration of a 4.54-acre wetland floodplain. This project was designed utilizing a hybrid of natural channel design and floodplain reconnection approach. Beneficial outcomes of this project included greater stability within the stream channel and stream banks, floodplain accessibility, and habitat and biodiversity recruitment post-construction. RES’ work on this project included property owner recruitment and buy-in during site selection evaluation, design, permitting, and construction.  

The Tarnans Branch watershed continues to develop rapidly with yearly increases in the overall impervious area upstream of this site; the implementation of the RES approach will result in the reduction of 659 pounds of phosphorus, 1,431 pounds of nitrogen, and 38 tons of sediment per year for this watershed. 

This project required close coordination with several interested project participants and entities including the property owner, SHA, Anne Arundel County, Maryland Department of the Environment (MDE), the US Army Corps of Engineers (USACE), and various subcontractors and suppliers. RES’ coordination and logistics among the project participants allowed for the successful and on-time delivery of this work.  

The Tennessee Department of Transportation (TDOT) selected RES to provide environmental mitigation credits to offset unavoidable environmental impacts due to roadway projects across Tennessee. RES was awarded three sites, resulting in a total of 68,593 linear feet of stream restoration, enhancement, and preservation.

For each, RES is responsible for site selection, land acquisition, survey, design, permitting, construction, monitoring, and adaptive management to support the TDOT’s restoration goals. RES is performing restoration efforts in multiple locations across the state including the Chattanooga, Knoxville, and Memphis area. Environmental feasibility services provided by RES included delineation of wetlands and streams on the site subject to jurisdiction by the US Army Corps of Engineers (USACE) under Section 404 of the Clean Water Act. RES utilized the currently accepted 1987 Corps of Engineers Wetlands Delineation Manual, and appropriate Regional Supplement, to delineate and flag potentially jurisdictional areas on-site, as well as collect all necessary data. Stream construction tasks will consist of mobilization, erosion and sediment control installation, clearing and grubbing, maintenance of stream flow, rock/log structure installation, riffle grade control installation, bank stabilization matting, seeding, and planting.

The overall goal of the Bank is to restore, to the greatest extent possible, the ecological function of the highly degraded aquatic resources with each of the sites. A primary objective of achieving this goal will be to generate stream compensation credits that fully mitigate authorized losses of streams, which are waters of the U.S. (WOUS), in a manner that best contributes to the long-term ecological health of the watershed. The Bank will accomplish this objective through the implementation of various mitigation measures, including stream re-establishment, restoration, enhancement, and riparian buffer planting. These activities are intended to produce watershed-scale improvements of ecological services that will replace the chemical, physical, and biological function of stream channels and riparian areas within the proposed service area lost as a result of authorized impacts.

The goal of this 397.51-acre Nutrient Bank located in Northumberland County is to reduce nutrient (phosphorus) and sediment loading into the Potomac River watershed via the conversion of active agricultural land into forest; and generate non-point nutrient credits for transfer under existing and future federal, state and local law, programs, regulations and guidance. The site primarily consists of agricultural land in row crop production and fallow land that was deforested around 2012. This site is within eight-digit hydrologic unit code (HUC) 02070011, and twelve-digit HUC 020700110804.

In 2007, RES partnered with the Prince William County Department of Parks and Recreation (PWC) to restore approximately 147,000 LF – well over 20 miles – of stream and riparian buffer on almost 2,000 acres of parklands. RES established a public-private partnership (P3) with PWC to enable stream restoration across the County at no cost to the County by combining the benefits of stream restoration and preservation within PWC parks with the demand for stream mitigation credits in the watershed. The Prince William Environmental Bank (PWEB) is the only P3 agreement of its kind in the Commonwealth. All design, permitting, planning, and construction are being implemented by HGS. The most recent project completed under this program is a 7,215 LF stream restoration at James Long Park in Haymarket, VA. HGS provided all design, permitting, and construction for the project. Within the park, 14,850 LF of streams and 109 acres of riparian buffer were protected by conservation easements, while 7,215 LF of impaired streams were restored. HGS field ecology staff currently monitor James Long for compliance with success criteria. Annual reports are submitted to the Virginia Department of Environmental Quality and the US Army Corps of Engineers to demonstrate project success.

RES is providing stream restoration credits to Prince George’s County Maryland Clean Water Partnership (CWP) program. The CWP is a Public-Private Partnership formed to meet the US Environmental Protection Agency’s (EPA) Clean Water regulatory requirements. The projects delivered through this contract will be enrolled as part of Prince George’s County Bay TMDL Action Plan, with associated nutrient reductions credited toward compliance with the Bay TMDL. The Tributary to Mattawoman Stream Restoration Project restored 4,926 LF of degraded stream channel, generating 98.53 Equivalent Impervious Acre Credits for CWP / Prince George’s County.  

To execute this project RES performed existing site assessments and geomorphic surveys. Using this data along with Natural Channel Design philosophies and published reference data, RES designed bankfull channels that provided stable banks and frequent floodplain connectivity. RES designed full realignments of the streams to achieve proper stream sequencing and stable channel geometry. Additionally, RES ensured that there were no offsite floodplain rises and performed all necessary hydrologic and hydraulic modeling. RES acquired all state, federal, and local permits necessary to execute the proposed work.  

Upon completion of the design and permitting, RES’ construction staff used a team of subcontractors and in-house construction crews to execute the project. Construction began in January 2021 and was substantially complete by May 2021. During construction, RES’ design staff remained an integral part of the team making frequent site visits, attending multiple site meetings, and ensuring the proper execution of the design.  

The goal of this 31.89 acre nutrient bank located in Henrico County is to reduce nutrient (phosphorus) and sediment loading into the James Watershed via the conversion of active agricultural land into forest; and generate non-point nutrient credits for transfer under existing and future federal, state and local law, programs, regulations and guidance. The site primarily consists of cropland, hayfield, and pasture. The land use conversion will generate 389.96 pounds of nitrogen reduction and 60.57 pounds of phosphorus reduction.

The Twiman Mitigation site is located within a rural watershed dominated by agricultural and low-density residential land use in Yadkin County. The project is located in the Yadkin River Basin within Cataloging Unit 03040101, 14-digit USGS HUC 03040101130010 and DWR sub-basin 03-07-02. The project area is comprised of three easement areas totaling 30.5 acres along multiple tributaries that flow into North Deep Creek. The project is designed to help meet compensatory mitigation requirements for warm stream impacts in the HUC 03040101.

The project proposes to restore 4,074 LF and enhance 5,074 LF of warm stream, producing warm SMUs. The streams proposed for restoration have been significantly impacted by livestock production, impoundments, agricultural production, and lack of riparian buffer. Goals for the Project include an increase to hydrologic function and restoration to ecological function within the existing stream and riparian corridor and protecting these features in perpetuity. These will be accomplished by removing two farm ponds, returning the existing streams to stable conditions, reconnecting channels to their floodplain, and backfilling the abandoned channels. In-stream structures will be utilized for vertical stability and to improve habitat. Buffer improvements will filter runoff from agricultural fields, thereby reducing nutrient and sediment loads to the channel. Livestock exclusion fence will be installed along the easement boundary. Benefits from these activities include improved water quality, and terrestrial and aquatic habitat. Construction is nearly complete as of May 2020.

The goal of the bank site is to restore and preserve self-sustaining, functional, stream, wetland, and riparian corridors to replace the functions and values lost from adverse impacts to streams and wetlands due to various permitted development projects within the Upper Susquehanna River Subbasin. The development efforts provide an in-kind replacement for the direct loss or functional degradation of stream, wetland, and riparian resources that result from unavoidable aquatic resource impacts. In addition, the structural establishment of these functional improvements in advance of the compensated functional impacts will serve to eliminate the temporal loss of function which may result from alternative mitigation approaches.

The project includes restoration of all stream channels onsite and the rehabilitation or conservation of their associated riparian zones. Some of the targeted aquatic functions restored include improvements to wildlife habitat, water quality, flood conveyance and storage, and erosion control through the implementation of natural channel design, vegetation controls, and long-term land protection. Restoration modifications include natural channel design techniques, channel cross section and pattern alterations, bank stabilization and bio-engineering techniques, grade control and in-stream structures, and establishment of forested riparian zones. Our work rehabilitates and conserves riparian zones along both banks of streams including wetlands.

This mitigation bank encompasses 134.43 total acres of land to be protected in perpetuity. The bank restores and preserves self-sustaining, functional stream, wetland, and riparian corridors and replaces the functions and services lost from adverse impacts to streams and wetlands due to various permitted development projects within the Upper Susquehanna River Subbasin. These development efforts will provide an in-kind replacement for the direct loss or functional degradation of the stream, wetland, and riparian resources that result from unavoidable aquatic resource impacts. Also, the structural establishment of these functional improvements in advance of the compensated functional impacts will serve to eliminate the temporal loss of function that may result from alternative mitigation approaches.

The Uzzle Stream Mitigation site is located in Johnston County, approximately six miles southeast of Clayton in the Neuse River Basin within the HUC 03020201. Water quality stressors affecting the site include livestock production, agricultural production, and improper flow dynamics due to impervious surface runoff. Goals for the site include an increase to hydrological function and restoration to ecological function within the existing stream and riparian corridor and protecting these features in perpetuity. These goals have been accomplished by returning streams to stable conditions by constructing channels with appropriate dimensions and pattern. Riparian buffer improvements also were constructed to filter runoff from the agricultural fields and neighboring car lot, thereby reducing nutrient and sediment loads to the channel. Livestock exclusion fence was installed along the easement boundary. Benefits from these activities include improved water quality and terrestrial aquatic habitat. The site presents 5,897 linear feet of stream restoration and enhancement generating 2,876 Stream Mitigation Units along Little Poplar Creek and two unnamed tributaries and 268,834 SF of buffer enhancement credits. Construction was completed in 2019.

RES supplied the mitigation offset solution for Volvo’s 1.5 million square foot manufacturing facility on a 575-acre tract in Berkeley County, South Carolina. RES developed a comprehensive Permittee Responsible Mitigation (PRM) work plan for preservation, enhancement and restoration of 2,458 acres of protected land, including permanent protection of 1,533 wetland acres in the Dean Swamp and Walnut Branch watersheds, tributaries of Four Hole Swamp that are defined by the National Audubon Society as critical priority areas in need of protection.

The primary mitigation tract placed 1,667 acres under a permanent protective agreement with the South Carolina Department of Natural Resources and the Low Country Land Trust, with the intent to dedicate the tract as a Heritage Trust Preserve. This tract includes 905 acres of wetland preservation and enhancement and protects 2.64 miles of Cedar Swamp, Sandy Run and associated unnamed tributaries.

The other tracts in the mitigation work plan included the protection and enhancement of 629 acres in Four Holes Swamp. These tracts will be owned and managed as part of the 17,000-acre Audubon Center and Sanctuary at Francis Beidler Forest, a Ramsar Wetlands of International Importance and Globally Important Bird Area.

Through a collaborative approach with the South Carolina Department of Commerce, leading private company experts, federal and state regulatory agencies, and regional conservation groups, Volvo was able to permit one of the largest economic development projects in South Carolina in record time. And, the effort resulted in the restoration and protection of 2,458 acres of land critical to protecting one of South Carolina’s natural treasures, Four Hole Swamp.

The goals of the bank are to enhance the vegetation of 267 acres of relic wet pine savanna and Carolina bay through prescribed burning, mechanical treatment, and chemical treatment as necessary, and to preserve 248 acres of fully functional Carolina bay and relic wet pine savanna. This site provides preferred conditions for many rare and endemic plant species occurring within the Southeastern United States.

The Walnut Shade Mitigation Bank is located in northern, middle Tennessee, approximately 57 miles northeast of Nashville in the eastern part of Macon County in the Town of Red Boiling Springs. This 321-acre property has historically been used for agricultural pasture, hay, and cropland and includes seven impoundments of 21,141 linear feet headwater perennial and intermittent streams. Current stream conditions show signs commonly exhibited by livestock access and extensive channelization including significant sections of eroding and sloughing banks, sparse riparian canopy, and excessive sedimentation resulting in embedded substrate. Consequently, current degraded stream reaches are potentially contributing to water quality issues such as nutrient overloading, turbidity, total suspended solids, and elevated water temperature.

RES is using natural channel design and construction techniques to restore channel hydrology, geomorphology, water quality, and aquatic and riparian habitat. The Walnut Shade mitigation bank will rehabilitate, reestablish or enhance 21,103 linear feet of stream. The Bank’s proposed primary service area watersheds are the Barren River (HUC 8 – 05110002), Red River (HUC 8 – 05130206), Upper Cumberland-Cordell Hull Reservoir (HUC 8 – 05130106), Old Hickory Lake (HUC 8 – 05130201), and Cheatham Lake-Lower Cumberland Sycamore Creek (HUC 8 – 05130202) as a secondary service area.

The Wolf King Mitigation Bank is located within the Neuse River Basin (03020201) in Wayne County. The project restored 8.75 acres of riparian habitat that was extensively used for agricultural production for over 50 years. Water quality stressors that were affecting the site included pollution from crop production, lack of forested riparian buffer, and manipulation of stream features within the project area. The buffer conditions were significantly degrading with the loss of stabilizing vegetation because of continued crop production.

The goal of the project was to restore and preserve the ecological function of the existing stream and ditch features and their associated riparian buffer areas by establishing appropriate plant communities while minimizing temporal and land disturbing impacts and permanently protecting the newly restored buffer in perpetuity through a conservation easement. Buffer and surrounding riparian area improvements will filter runoff from agricultural fields, thereby reducing nutrient and sediment loads to the site channels and provide water quality benefit to the overall watershed. The bank generates riparian buffer mitigation credits and nutrient offset credits.

York Nutrient Bank is an 86.3-acre property located in New Kent County. The land conversion area within the bank encompasses 44.79+/- acres. During the 2005 baseline date, the property was cultivated for hay and utilized as pasture. It was planted with various hardwood species in the winter of 2015.
