Harlem Meer Pool and Rink Reconstruction

OVERVIEW
Restoration of Central Park’s northern end includes the redevelopment of the Lasker Rink and Pool facility on the Harlem Meer; improvements to the shoreline; construction of a boardwalk and pergola; and replacement of invasive plant materials with sustainable emergent aquatic plantings. Langan prepared an environmental assessment statement; performed geotechnical investigations (including borings); provided recommendations and design requirements for support of new structures, slope stabilization, and design of Support of Excavation; and filed permits with multiple New York City agencies. We also conducted on-site design for the new facility, including grading, stormwater drainage, utilities, stream-daylighting, Specifications for Erosion and Sediment Control, Stormwater Pollution Prevention Plan, and construction details. Once complete, the rehabilitated space will be a vital resource for the surrounding community, providing a scenic, recreational area for visitors.

The Boathouse at Canal Dock

OVERVIEW
Langan was the prime consultant for the state and federally funded Canal Dock project. The project involved the construction of a 48,000-SF pile-supported platform to support a 30,000-SF community boathouse, the stabilization and reconstruction of over 1,500 LF of shoreline, and the revitalization of Long Wharf Park. This rare facility, completed in September 2018, provides a destination and a much needed access to the waterfront for the entire community. Langan began environmental permitting in the early 2000s culminating with obtaining rare state and federal permits to construct a platform over the water. Langan oversaw a multidisciplinary design team, and provided waterfront, geotechnical, and site/civil engineering, surveying and landscape architecture services.

Presidio of San Francisco

OVERVIEW
Since 2000, Langan has provided as-needed consulting services at Presidio National Park, formerly an Army base. Some key projects include:

Environmental Remediation: We have assisted with the remediation and closing of 12 distinct sites within the Presidio (including the “clean closure” of four uncontrolled landfills), preparing documents spanning the full range of CERCLA (Superfund) and Petroleum Hydrocarbon cleanup activities.

Groundwater Monitoring: Tasks include sounding, purging, and sampling over 200 wells, installing wells, managing and interpreting the chemical data, and producing a groundwater monitoring report for each sampling period using GIS.

Slope Stability: After a historical road was uncovered and restored, we performed a slope stability analysis, provided slope strengthening design, and evaluated the stability of a retaining wall. The project involved coordination with public agencies, regulatory agencies, and citizens because the Lyon Street Steps are located on federal land adjacent to residential property.

The High Line

OVERVIEW
The project involved the transformation of an abandoned, elevated railroad structure into a popular public park. Stretching 1.5 miles on Manhattan's west side, the park helped spur residential and commercial development in the West Chelsea neighborhood and is a popular tourist attraction. Langan's site/civil group assisted with the design and permitting of three plazas associated with the High Line, and obtained DEP drainage plan permits to connect drains for the project areas and at street level for the length of the structure. Our environmental team provided remediation design and oversight for the section of the park between West 17th Street and West 18th Street.

Salesforce Transit Center and Salesforce Park

OVERVIEW
Since 2007, Langan has provided environmental consulting services for the demolition of the former Transbay Transit Center and ramps, which spanned three city blocks, and construction of Salesforce Transit Center and Salesforce Park. The transit center centralizes the Bay Area regional transportation network, including below-grade levels for trains, above-grade levels for buses, and a rooftop public park. Sustainable features include light columns on the roof to save electricity by bringing natural light into the interior of the building, as well as intricate landscapes designed to absorb carbon dioxide from bus exhaust and recycle stormwater. This project is the centerpiece of a transit-oriented neighborhood providing space for the community to live, work, shop, and enjoy the outdoors, all within walking distance.

Meridian Hill Park

OVERVIEW
Meridian Hill Park sits on a hill a little over a mile and a half north of the White House. Langan performed a variety of services for design and data collection for Phases V and VI of the Meridian Hill renovation project. In the Lower Plaza, Langan provided an accessible route into the lower level of the park from 16th Street, which consisted of three ramps that complied with the Architectural Barriers Act Standards. Langan also performed a geotechnical investigation, which consisted of concrete coring, geotechnical dynamic cone penetration tests, and soil sampling at the south portion of the park near the James Buchanan Memorial.

Freshkills Park – South Park

OVERVIEW
Once home to the 2,200-acre Fresh Kills Landfill, the world’s largest landfill, this site is currently undergoing a transformation to become Freshkills Park, New York City’s largest new park in over a century. Once complete, it will be three times the size of Central Park. The South Park is the latest addition to the project’s phased construction. For this phase, Langan helped develop the landfill gas mitigation system and an innovative stormwater management system. With a focus on sustainability and resiliency, we successfully designed the site layout, utility locations, and stormwater management systems to minimize disruption to wetlands and forested areas, and reused areas of degraded ecologies for stormwater capture. We also prepared an innovative pollution prevention plan, establishing the sampling required to monitor construction and post-construction runoff at new discharge points.

DMAVA Park and Hudson River Walkway

OVERVIEW
DMAVA Park and Hudson River Walkway is a public waterfront park offering sweeping views of Lower Manhattan and the New York Harbor, as well as the home of the historic Colgate Clock. This project responded to the environmental, historical, and recreational challenges of the property, specifically the movement of goods and cargo nearby and the historic migrations of people through nearby Ellis Island and the Statue of Liberty. Langan designed this project for the NJDEP, including 1,600 linear feet of waterfront walkways, a bulkhead and waterfront esplanade, a timber boardwalk, and a three-acre park along the Morris Canal Basin, across from Liberty State Park. Our sensitive approach to preservation and ecologically-based engineering helped interpret and magnify this history while reconnecting Jersey City to its waterfront.
