Since our founding in 2010, ECS has completed more than 180 project spanning from the Gulf Coast to California.  This work has included a diverse array of services. Cultural resource projects have ranged from inventories to mitigative documentation to preparation of NRHP nominations and determinations of eligibility to preparation . Environmental projects include various NEPA documents, biological modeling studies, groundwater testing, and GIS-based fire studies. Staffing in the past three years alone has involved multiple positions for Colorado BLM; technical support for tribal cultural resource efforts in South Dakota; and senior level cultural resource compliance expertise for the Deepwater Horizon cleanup in the Gulf of Mexico.  The following represent a sample of representative projects.

ECS Expertise

Sample Projects

Deepwater Horizon Section 106 Response Team, Alabama, Florida, Louisiana, Mississippi

ECS was contracted by the National Park Service Southeast Archaeological Center to provide the US Coast Guard with qualified staffing for Section 106 compliance activities associated with the BP Deepwater Horizon Spill in the Gulf of Mexico. Four positions were required and included Tribal Coordinator, Tribal Liaison, SHPO Liaison, and Lead Ethnographer. The project provided compliance support for the entire response area that covered the length of the Gulf Coast from Louisiana to Florida. ECS’ main goal was to facilitate completion of numerous tasks to wrap up a four-year undertaking managed under Section 106 Emergency Procedures. This required coordination with numerous federal agencies and ethnographic communities across region. Tasks include:


• Ethnographic and Traditional Cultural Properties review support

• Archaeological compliance review support

• Weekly and monthly project reporting

• Assistance with planned final reports for all compliance activities completed within the four-state region during the course of the clean-up effort


ECS also provided value added independent compliance review for draft cultural resource and TCP reports completed by subconsultants for NPS and the Coast Guard. NPS expressed appreciation for ECS providing the report services and noted that our comments were consistent with both internal and Advisory Council on Historic Preservation document review. This contract was terminated early, upon completion of all project tasks, and scale down/close out of activities by the Coast Guard in the Spring of 2015.

Conservation Activities for USACE, Albuquerque District

ECS is under contract to USACE Albuquerque District to provide one of their federal facility clients large scale cultural resource inventory services in compliance with Section 106 of the National Historic Preservation Act (36 CFR 800). ECS’ main goal was to perform pedestrian archaeological inventory of 12,000 acres of multiple outlying ranges while also relocating and re-recording previously recorded isolated finds and sites within the designated areas. This work was undertaken in areas of extreme terrain and weather conditions in Southern Arizona and required complicated (and constant) range coordination. All project staff also had to pass background tests and complete ECS managed (and USACE approved) safety training.


Fieldwork was completed between January and July of 2016 and was undertaken in multiple locations spanning an area of more than 1,000 square miles in two counties. In order to facilitate efficient completion of field tasks, ECS employed a variable size crew ranging from three to eight personnel. ECS supervisors also coordinated daily with client personnel regarding range access and safety requirements.  Because of crew safety considerations identified by ECS in consultation with the client, our efforts were relocated on several occasions during the course of the work. Running acreage were relayed regularly to the client to allow for full allocation of survey acreage within the known range limitations. In total, more than 90 archaeological sites and 1,000 isolated occurrences were recorded during field efforts. Results were contracted to be presented to two reports. The first report has been completed. According to USACE, this report was approved with no comments by Arizona SHPO. The second report is currently being prepared.

Project challenges consisted of handling, transporting, and disposing of tested samples in accordance with Investigative Derived Waste procedures; transporting samples daily to testing facility from a remote setting; and processing utility reimbursement for wells on private property. ECS personnel have worked closely with the USACE to assure property access on reoccurring schedule, and expedite sampling, analysis, and reporting.  All work has been completed on schedule and has met client expectations.

USFS Region 2 Cultural Resource Services IDIQ

ECS has been under contract since 2014 to provide cultural resource services to USFS Region 2. Although the contract was originally setup for work in San Juan National Forest, it has been expanded to include all Region 2 forests and grasslands.  The IDIQ consists of projects of various sizes that have a quick turnaround time and are completed via a unit pricing model. Projects have also been undertaken simultaneously in multiple forests and have involved coordinating with cultural resource and range personnel in each location. Finally, work has covered a wide variety of terrain and has involved rugged, remote settings that require four-wheel drive and pedestrian access. ECS has worked closely with agency personnel to coordinate and expedite tasks and has employed an aggressive QA program to ensure both quality and cost efficiency.  Tasks have included:


• Class I, II, and III cultural resource survey investigations, ranging in size from 15 to 2,200 acres.
