Land Management Group has been successfully completing projects for our clients since 1991 and we are proud of our accomplishments. Recent projects are listed below.
Helmsport Marina & Subdivision
Location: New Hanover County, NC
Project Overview: In 2013, LMG began work with the developer to plan a residential marina that could be successfully permitted based on the various water quality and natural resource conditions present at the site. Early on, meetings were held with federal, state, and local agencies to discuss design parameters that would be beneficial to the project as well as the environment. Delineations of 404 and coastal wetlands were performed and approved prior to surveying. This produced an accurate planning base map for the marina and subdivision layout. Impacts to wetlands were avoided where possible and minimized where they were necessary. As mitigation for the marsh fringe impacts, an area suitable for coastal wetland restoration was identified where an old upland berm through the marsh was removed, graded to intertidal contours and planted with Spartina alterniflora. Yearly monitoring of that planted area is ongoing with reports submitted to the Corps of Engineers. Environmental approvals that were received for the project included a CAMA Major Development Permit from the NC Division of Coastal Management, a Corps of Engineers General Permit 291 and a 401 Water Quality Certification from the NC Division of Water Quality.
Bay River Metropolitan Sewer District
Location: Pamlico County, North Carolina
LMG worked with the Bay River Metropolitan Sewer District (MSD) for the purposes of increasing the overall wastewater effluent capacity at the Arapahoe sprayfields for the future developmental potential of Pamlico County. The Arapahoe sprayfields are located on a 511 acre tract of land located off NC Highway 306. In 1993, 137 acres of land were permitted by the North Carolina Department of Environment and Natural Resources (NC DENR) Division of Water Quality to utilize as sprayfields at the site. The overall flow rate permitted in 1993 was 495,000 gpd.
LMG reevaluated the property in 2011 to determine if there was additional wastewater capacity at the site. LMG performed a 404 wetland jurisdictional determination on the site in 2011 that was approved by the US Army Corps of Engineers. LMG performed a detailed soil mapping and analysis at the site to map out all of the additional suitable soils with the potential for wastewater disposal. LMG then conducted a detailed hydrogeological assessment on the underlying unconfined aquifer and utilized the Modflow groundwater computer modeling program to mimic the observed current groundwater equipotentiometric surface. LMG successfully generated a groundwater computer model to demonstrate the mounding potential of the unconfined aquifer of the site. LMG utilized the groundwater computer model to demonstrate to NC DENR under the current 15A NCAC 02T Wastewater Dispersal rules that increasing the flow rate in some of the current permitted sprayfields coupled with utilizing an additional 6 acres of suitable land at the property that the overall wastewater effluent flow rate capacity at the site could be increased by 147,000 gpd for a new total capacity of 642,000 gpd.
Project Overview: Brunswick Forest is a 4,600 acre planned community situated in Leland, North Carolina along Town Creek. Final plans called for nearly 10,000 home sites and several hundred thousand square feet of commercial shopping center space at the entrance of the project.
LMG provided turn key environmental services at all phases of the development. We delineated freshwater and coastal wetlands throughout this large site and performed stream determinations utilizing the NC Division of Water Quality assessment methods. Extensive studies monitored groundwater levels to provide the most accurate wetland line across portions of the development. This data also served as baseline data for ensuring compliance to NC DENR's guidance for groundwater standards as it relates to stormwater Best Management Practices.
Our knowledgeable staff was able to obtain approval of the wetland line from the US Army Corps of Engineers in a relatively short time frame.
LMG worked closely with the project developer during the design of the site plan to minimize environmental impacts. Brunswick Forest was able to utilize existing roads, construct bridges, and narrow the footprint of new roads in order to reduce wetland and stream impacts as much as possible. LMG applied for and obtained a Nationwide 29 Permit from the US Army Corps of Engineers and a 401 Water Quality Certification from the NC Division of Water Quality for unavoidable wetland and stream impacts. Additionally, LMG obtained a CAMA Major Permit from the NC Division of Coastal Management for a beach club amenity and for a boat landing on Town Creek.
Soil scientists at LMG also performed detail soils analyses throughout different phases of the development in order assist the planners and engineers to determine the most suitable locations of the required stormwater facilities.
South Harbour Village Marina
Location: Southport, NC
In 1997, LMG began work to obtain necessary CAMA, Corps of Engineers and Division of Water Quality permitting for South Harbour Village Marina. A jurisdictional wetland delineation was performed and approved as part of the planning process and LMG was involved in marina siting and land use consultation with the developer. As part of a larger overall development, the marina site was planned in the location of a former menhaden processing plant. The mixed uses surrounding the marina basin include restaurants, bed and breakfast units, offices and single family residential housing. Through the years since the original construction, LMG has renewed and modified the marina permit to allow for additional and reconfigured boat slips, maintenance dredging, development of a permanent designated dredge disposal site and the installation of submerged silt curtains to help reduce sedimentation within the basin. Today, South Harbour Village Marina remains a well maintained and popular boating destination.</
Project Overview: Land Management Group (LMG) conducted environmental studies related to the design and permitting of the relocation of Mason Inlet in New Hanover County, NC. In conjunction with Applied Technology & Management, Inc. (ATM), LMG prepared and submitted an Environmental Assessment that included a project alternatives analysis, Biological Assessment (Threatened and Endangered Species report), and an Essential Fish Habitat report. A CAMA Major Permit as well as Section 404 and 401 Permits were obtained for the inlet relocation, including the marsh area impacted by the widening of Mason's Creek.
In addition, LMG developed a tidal salt marsh restoration plan designed to offset project impacts to the marsh habitat. A former US Army Corps of Engineers (USACE) dredge disposal island located adjacent to the AIWW west of Figure Eight Island was identified for the wetland restoration. LMG conducted wetland delineations, vegetative mapping, and soil borings on the island to provide baseline information for the project design. LMG coordinated and supervised the installation of 81,000 coastal wetland plants within the constructed intertidal and high marsh habitats on the island. The tidal salt marsh restoration project has successfully restored high marsh, low marsh, and primary nursery habitats. LMG is currently working with New Hanover County and federal and state agency personnel to ensure permit compliance. Our staff implemented a biological monitoring plan and a waterbird habitat management plan in accordance with US Fish & Wildlife Service (USFWS), National Marine Fisheries Service (NMFS) and USACE requirements.
Rutman Creek Watershed Restoration
Location: Roper, North Carolina
Project Summary: Land Management Group, Inc. (LMG) was contracted to provide site specific mitigation for the mine expansion project proposed by PCS Phosphate in Aurora, NC. This expansion will result in extensive wetland and stream impacts, requiring a multiple large-scale projects throughout the lower Tar-Pamlico River Basin. In order to meet these challenges, LMG initiated an extensive search throughout Hyde, Beaufort, and Pamlico counties. A large, contiguous farm located in the headwaters of Rutman Creek (Hyde County) was targeted as a potential restoration site. The parcel included over 3,000 acres of actively cultivated farmland and approximately 1,000 acres of bay forest habitat that was relatively undisturbed. In addition to the extensive acreage the site also contained opportunities for zero order stream restoration and enhancement in the lower reaches of Rutman Creek.
As the principal consultant, LMG provided the following services during the mitigation site development process: 1) Identification of potential mitigation resources 2) Preparation of restoration plan documents 3) Coordination of project with Interagency Review Team (IRT) 4) Conducted on-site hydric soils/wetland delineation 5) Identification of reference wetland sites 6) On-site construction management for both wetland and stream components 7) Conducted annual vegetation and physical monitoring (2009-2016).
Overall,the Rutman Restoration project appears to be performing very well. Vast areas of headwater wetlands that had been historically drained and converted to commodity crop production have been restored. As a part of the watershed restoration effort, the hydrologic regime of first-order and zero-order tributaries that had been previously disconnected from their headwaters (via diversion canals) has been re-established.
Given the intensive land-use practices of the area prior to restoration work, the canals and downstream receiving waters were susceptible to water quality impairments via nutrient (e.g N and P) loading, sediment run-off, and herbicide/pesticide contamination. Restoration work has removed the intensive lan-use practice and associated stressors to water quality. In addition, planting of all the fields provides water quality benefits via: (1) reducing overland flow velocities; (2) stabilizing soil; and (3) promoting the uptake and transformation of nutrients/contaminants. Removal or plugging of canals provides for increased flood water storage, increased hydrologic residency, and associated nutrient/sediment retention. Lastly, the restoration site provides significant habitat benefits as well as habitat connectivity between Pocosin Lakes National Wildlife Refuge and the riverine swamp forests of Rutman Creek and the Pungo River.
Bachelors Delight Stream and Wetland Mitigation Bank
Location: Jacksonville, North Carolina
On behalf of Weyerhaeuser Company (owner and Bank Sponsor), Land Management Group served as the lead consultant for environmental site investigations, design, permitting, implementation, and monitoring of the Bachelors Delight Stream and Wetland Mitigation Bank (an approximate 363-acre wetland and stream mitigation site). The Bank site is located approximately 2 miles north of the City of Jacksonville in Half Moon, Onslow County, North Carolina and includes lands owned by both Weyerhaeuser and NC State University (Hofmann Forest). The project is located in an identified Targeted Local Watershed of the White Oak River Basin and consists predominantly of channelized headwater wetland and stream systems that have been historically altered as a result of silvicultural and agricultural management practices. Streams and waterbodies within the watershed are susceptible to impairment from nutrient loading and low ambient dissolved oxygen (DO) concentrations.
In conjunction with the stream designer, LMG oversaw construction management and planting. Functional uplift to stream reaches and associated adjacent wetlands have been achieved via the re-establishment of natural hydrologic and vegetative conditions that existed prior to the initiation of intensive land management in the early 1970s. Re-establishment of native vegetative communities suited to the landscape position and soil types of the project area provide for enhanced feeding and refuge habitat for resident and migratory species. Restoration and protection (via the conservation easement deed) of the riparian and non-riparian wetlands provides a habitat corridor from expansive wetland flats of Hofmann Forest to downstream bottomland hardwood forests of Bachelors Delight Swamp and New River.
