EQ staff prepared the Restoration and Maintenance Plan (RMP) for the 1-mile-long Pettibone Ravine at the Great Lakes Naval Training Center (GLNTC) in Great Lakes, Illinois.   This 5,000-acre watershed and ravine system drained directly into Lake Michigan.   Property development activities, natural erosion processes, proliferation of invasive plant species, and the lack of a maintenance program collectively resulted in the degradation of the ravine system.   EQ completed pre-assessment research and a field assessment (geotechnical and ecological) to characterize the areas of potential slope failure and to identify the indigenous and invasive flora.   EQ then prepared the RMP into a master plan that coupled Best Management Practices with the latest advances in natural biotechnology.

EQ conducted remediation and regulatory site closure at the former Ft. Sheridan (BRAC facility) for transfer to private ownership and redevelopment into a residential community.   Remedial actions included containment, excavation, and removal of landfill waste and leachate; stormwater management; waste transportation and disposal; on-site waste recycling; and preliminary site restoration, environmental construction, and planting.   EQ removed all wastes and impacted soils (197,857 cubic yards) from former military landfills during remediation.   Because the exact nature of the buried waste was unknown, EQ maintained UXO readiness during all excavation operations.

EQ remediated a 20-acre wetlands in Lake Geneva, Wisconsin that was a former trap and skeet shooting range.   This wetland area was drained, contaminated sediments were removed, and the entire wetland area was reconstructed and maintained for 2 years.   EQ prepared the restoration plan during the winter and executed the plan the following spring.   The wetland area was comprised of xeric and mesic prairies (7.5 acres); wet prairie (4 acres); sedge meadow (1 acre); water periphery, 1- to 6-inch depth (1 acre); shallow marsh, 4- to 8-inch depth (2 acres); and marsh, 6- to 18-inch depth (2 acres).   EQ replanted each of the areas, constructed fish and waterfowl enclosures, and performed short- and long-term maintenance that included annual burns, herbicide application, and mowing.

Under a CR task order issued by USEPA Region 10, EQ performed a time-critical response at an abandoned lead and silver mining and milling facility located in the remote Sawtooth Wilderness Area of central Idaho.   EQ was tasked to prevent the collapse of an unstable mine tailings pile into Kinnikinic Creek and the Salmon River, and to take necessary steps to stop migration of zinc and arsenic from the pile into the local air and waterways.   The tailings pile was 200 feet high, contained by earthen dams, and situated over unstable fill.   EQ used stabilization methods to relocate the creek running along the tailings pile, buttressed the toe of the pile, and capped unprotected areas to prevent migration and runoff.   EQ performed remedial design, road construction, creek restoration/construction, capping, and site restoration. 

EQ was responsible for the design and implementation of a new master plan for a 22-acre all-native plant botanical garden and preserve located in Highlands, North Carolina.   EQ's master plan included the reclamation of disturbed sites; installation of theme gardens; and improvement of trails, boardwalks, and bridges.   The project's scope also included naturalized area enhancement (wildflower meadows, bogs, woodlands, etc.), semi-formal garden installation (azalea garden, amphitheater, etc.), and facility landscape augmentation (offices, nature center, housing, etc.).  EQ provided construction management utilizing local subcontractors for trail layouts and upgrades, earth moving, and landscape restoration and replanting.   EQ helped to develop both short- and long-term maintenance plans for the botanical garden and its upkeep. 

EQ produced and procured several interpretive panels and maps for a natural area in western North Carolina.   The panels were designed to foster learning, help interpret natural communities, and stimulate a more interactive experience for visitors to the natural area.   EQ was responsible for producing text, designing final layout, and creating graphics for each panel.   Interpretive panels were developed for several plant communities including old-growth hemlock hardwood forests, woodland wildflowers, ferns, wildflower meadows, and Southern Appalachian bogs.  EQ made recommendations for locating the panels and maps throughout the natural area.
