JURISDICTIONAL WETLANDS DELINEATION NATIONAL GUARD ARMORY - BURLINGTON, NC

DAVENPORT was requested to conduct a jurisdictional wetlands delineation on behalf of the North Carolina National Guard Construction and Facilities Management Office (NCNG-CFMO) as a part of the development and design process for capital improvements at various National Guard facilities across North Carolina. The National Guard Armory site is an approximate 5.19± acre parcel located at 1935 North Church Street in Burlington, Alamance County, North Carolina. An assessment of natural resources is required as part of an initial site assessment for the State Construction Office.


DAVENPORT provided turn-key environmental services during the initial phase of assessment. Potential wetlands were identified using the Routine On-Site Determination Method as described in the 1987 US Army Corps of Engineers (USACE) Wetlands Delineation Manual (1987 Federal Manual) and appropriate Regional Supplements. Streams were delineated per procedures specified by the USACE and the North Carolina Division of Water Quality (NCDWQ), where applicable. Services provided included coordination with state and federal agencies.


Our knowledgeable staff was able to obtain approval of our findings from the USACE in a relatively short time frame. DAVENPORT’s environmental staff has extensive knowledge of and experience with the identification and permitting of natural resources, which enables DAVENPORT to deliver quality work.

MARINE CORP BASE CAMP LEJEUNE, SOIL REMOVAL ACTIVITIES - CAMP LEJEUNE, NC

DAVENPORT, along with our sub-consultant CATLIN Engineers and Scientists, provided environmental services for this project. Our scope of work included activities necessary to conduct a soil excavation of petroleum-impacted soils to North Carolina State clean-up levels in an area where a 30,000-gallon underground storage tank (UST) had been previously removed. Based upon various environmental assessments, two areas in the vicinity of the UST were recommended to be excavated. Field screening of soils was performed to assist with defining the limits of the excavation. The excavation was extended approximately two feet into the water table to maximize the potential removal of free-phase product. Soil sampling and laboratory analysis was performed to confirm all contaminated soil exceeding required limits was removed.


DAVENPORT and CATLIN were able to work together in order to minimize interruptions to base activities. Coordination between our team and the base allowed a short planned outage while relocating a power pole. The project was phased in order to maintain traffic on the site, and to facilitate the abandonment and removal of approximately 11 groundwater monitoring wells that were located in close proximity to the area of excavation. The groundwater monitoring wells were replaced at the end of the project.


Upon project completion the site was restored to its previous condition including reconstruction of the asphalt parking lot areas. The final deliverables of this project included a soil cleanup report, as well as abandonment and construction records.

P-1346 AND THE RADIO BATTALION OPERATIONS COMPLEX - MCB CAMP LEJEUNE, NC

The P-1346 site, located at Camp Lejeune, is proposed for the new construction of administrative-type buildings including three proposed structures and associated parking lots and storm water retention ponds. DAVENPORT, along with our sub-consultant CATLIN Engineers and Scientists (CATLIN) provided environmental services to determine whether soil, groundwater, and/or other media at the proposed construction site was negatively impacted by historical activities at levels that would present unacceptable risks to human health and ecological habitats. Our scope of work included a historical assessment of the site, including site research and reconnaissance, the collection of soil, soil gas, and groundwater samples, an Ecological Risk Assessment and a Human Health Risk Assessment.


The work resulted in the preparation and submittal of a Preliminary Environmental Assessment report providing conclusions and recommendations for the site. Naval Facilities Engineering Command and the Navy and Marine Corps Public Health Center approved our findings and recommendations allowing the military construction project to move forward.

SITE REMEDIATION ACTION, FUTURE BUILDING G-484 (SITE P-1268) - MCB CAMP LEJEUNE, NC

DAVENPORT, along with our sub-consultant CATLIN Engineers and Scientist, provided professional services necessary to assist Marine Corps Installations East – Marine Corps Base Camp Lejeune with a goal of cleaning up detected contaminated groundwater that was discovered at a construction site during the removal of an existing waterline aboard Marine Corps Base Camp Lejeune.


The extent of the impact to the groundwater was horizontally and vertically delineated, and in an effort to clean up the impacted shallow groundwater the remediation action was conducted through the construction of injection wells, and the placement of an Oxygen Release Compound (ORC) product within the defined area of groundwater contamination. The goal of the ORC compound is to greatly enhance the natural attenuation occurring at the site. Our scope of work included activities necessary for the implementation of the remedial action plan in order to bring the levels of detected targeted compounds in the groundwater to levels below the North Carolina Groundwater Quality Standards (NCLGWQS) . At the end of the remediation activities an After Action Report was prepared and submitted to the proper state and federal agencies for approval.

WALLACE CREEK NORTH BEQ/ARMORY COMPLEX - MCB CAMP LEJEUNE, NC

DAVENPORT served as a subconsultant on this project, providing traffic engineering services related to operational improvements needed to an intersection on Parachute Tower Road due to the design build construction of a new BEQ and Armory Complex.


The project involved realignment of an existing T-intersection. DAVENPORT's scope of services included review of the original alignment design concept and preparation of a preferred preliminary design.


The preferred design was developed with consideration for maximizing safety and efficiency; matching existing features (such as roads, structures, etc.); minimizing environmental impacts, property impacts, overall construcion costs; and establishing suitable access for properties within the project limits. Our recommended/preferred design alternative utilized the standard right turn lane design which keeps right turning movement ajacent to through lanes. DAVENPORT provided a pros and cons narrative summarizing the advantages and disadvantages of the standard right turn lane design, as compared to the originial channelized right turn lane design.


Other services included a transportation management plan, and pavement marking and signing design.
