Former Gas Plant Remediation & Ecological Restoration

OVERVIEW
Langan developed and gained regulator agreement on a final remedy for a former major oil corporation gas plant site located in Southern California. The agreed upon path to closure utilized a background analysis and risk assessment to identify attainable remedial cleanup standards for constituents of potential concern. By taking a face-to-face approach with regulators (DTSC, Region 9 EPA, Central Coast RWQCB, County of Santa Barbara) and presenting a strong argument for a risk-based strategy to closure, Langan was able to achieve an agreed upon 1 to 2 year path to closure that was 27 years (case opened in 1988) in the making with two previous consultants.

The Glasshouse

OVERVIEW
The Glasshouse is a five-story, residential mixed-use building with over 300 apartment units, ground floor restaurant and retail space, and indoor parking. The project is extremely environmentally sensitive because of the location within the floodplain, site contaminants, and the ACT II process. Langan’s environmental team facilitated the ACT II process that helped to procure funding; addressed site contaminants and underground storage tanks; and developed a soil characterization and management plan to optimize re-use and disposal. Our site/civil engineers coordinated with the DEP, Allegheny County Conservation District, and City of Pittsburgh to develop a stormwater management plan that met City and DEP requirements while working with the site constraints.

UCHC Outpatient Pavilion and Parking Garage

OVERVIEW

The UCHC Ambulatory Care Complex is a design-build project with an aggressive delivery schedule. The project includes a 300,000 square-foot medical building and six-story parking garage. Langan is providing engineering, environmental permitting and surveying services. Site challenges include existing wetlands that require filling, a mass excavation over more than 70 feet in some areas, a need for flood management verification, and significant utility upgrades and reconfigurations on an active health care campus. The site design will incorporate environmentally sensitive stormwater techniques and the team is seeking LEED Silver certification for the project.

Cranbury Logistics Center

OVERVIEW
Langan prepared a general development plan submission for this 395-acre parcel adjacent to the New Jersey Turnpike. Langan’s integrated team of site/civil, geotechnical and environmental engineers and scientists prepared a design to construct 2.8 million SF of warehouse distribution on approximately 150 acres of the site. The full build-out of the business park includes three cross-dock warehouse buildings and is one of the largest wetland mitigation projects in state history. Proper remediation of the site required impact to nearly 50 acres of contaminated wetlands. In order to minimize impacts to forested areas, sparsely vegetated uplands were excavated to form shallow concave grades to allow water to accumulate in these areas, creating an amphibian habitat. An extended 10-acre stormwater basin was also used to create additional wetlands mitigation by designing planting shelves and islands within the basins to allow for wetland plantings to grow.

Bronx Point

OVERVIEW
Bronx Point is a 585,000-SF, mixed-use waterfront site comprised of 540 units of affordable housing, educational community facilities, commercial/retail spaces and open space adjoining the Harlem River waterfront in the Lower Concourse North area of the South Bronx. The site was previously a paved asphalt lot used for temporary storage by city and state agencies and recently underwent a rezoning to add the parcel to the Special Harlem River Waterfront District. Langan provided waterfront engineering services to create a resilient shoreline edge, by removing an existing relieving platform and creating a more natural shoreline slope to reduce tidal energy as sea levels rise. Site/civil engineering services included the design and permitting of underground utilities, permitting of two new stormwater outfalls to the Harlem River and onsite layout and circulation including a new private roadway. Environmental engineering services included completion of a Brownfield Cleanup Program (BCP) application, Remedial Investigation Program and Citizen Participation Plan.
