Brooklyn Navy Yard Brooklyn, NY Since 2009, RBA has designed and managed the redevelopment of all subsurface infrastructure within this 300+ acre industrial facility in Brooklyn. Installment of stormwater BMPs and reduction of CSO volumes were key aspects of all roadway and parking lot reconstruction. The Navy Yard’s industrial character and high water table posed special challenges in meeting stormwater reduction goals. RBA was able to meet these goals through the use of shallow stormwater management practices. 5

DESIGN SERVICES Permeable Pavements

Underground Storage Systems

Rain Gardens

The permeable paver system used was designed to achieve a superior lock-up that can withstand even the heaviest commercial loads. The permeable asphalt pavement system achieved a high void ratio by using a larger aggregate and a sizeable stone recharge basin that both supports the heavy vehicle loads and provides a significant storage capacity for stormwater.

NYCDEP Green Infrastructure New York, NY New York City’s Department of Environmental Protection (DEP) is currently developing Combined Sewer Overflow Long Term Control Plans for affected water bodies per the Clean Water Act and recently Amended Consent Order signed in March of 2012 with the New York State Department of Environmental Conservation. DEP’s intent is to use green infrastructure in order to meet water quality standards. RBA is providing design and construction services for green infrastructure in several combined sewer tributary areas. RBA is developing plans for green infrastructure installations on City-owned properties including streets, schools, and public housing. A variety of measures will be utilized, including green roofs, green streets, and bioswales. RBA also will supervise construction of these installations. 6

THE RBA TEAM IS Evaluating specific locations using GIS & record maps Analyzing impervious tributary area to manage 1” of runoff

Conducting topographic surveys Performing soil borings and permeability testing

Preparing construction docs for installation of 500+ bioswales. Performing construction management of green infrastructure


La Plaza de las Americas New York, NY NYCDOT works with selected nonprofit organizations to create neighborhood plazas throughout the City to transform under utilized streets into vibrant, social public spaces. The NYC Plaza Program is a key part of the NYC’s effort to ensure that all New Yorkers live within a 10 minute walk of quality open space. Plaza De Las Americas is a part of DOT’s Plaza Program, and an integral component of PlaNYC 2030.

The design of La Plaza de las Americas features a completely permeable pavement surface similar to one used at the US Cellular Field Parking Lot in Chicago. RBA also integrated a Silva Cell modular suspended pavement system that uses soil volume to provide urban trees with the space needed for healthy root systems, which supply powerful on-site stormwater management through absorption, evapotranspiration, and interception.

Nassau County Community College Hempstead, NY RBA designed a 20 acre/1400 car “green� parking lot and connecting roadways that incorporate permeable pavers, bioretention swales, rain gardens, LED light fixtures, raised planted islands, decorative pedestrian crosswalks, and mixed-in-place recycled base course. THIS PROJECT IS The Largest Application of Bioretention Swales in NY State


2013 ACEC New York - Silver Award

A Showcase for Sustainable Parking on Long Island

An Integration of Complete Streets, Green Infrastructure & Context Sensitive Design Principles


NYCDOT Permeable Pavement Retrofit on Urban Roadways New York, NY Streets comprise more than 25% of the City’s impervious land area. The NYCDOT is looking to capitalize on this available real estate by studying ways to incorporate porous pavements into the City’s fabric and complementing DEP programs to further reduce the burden of overland runoff on the combined storm sewer system. For NYCDOT RBA studied, analyzed, and developed standard details for porous pavement retrofits that can be installed by the City’s in-house maintenance staff. THIS WORK WILL INCLUDE Methodologies for evaluating hydraulic site conditions

Evaluation of Porous Friction Courses (PFCs)

Details for modifying the existing roadway to allow drainage

One-year monitoring of installations

Green Infrastructure – Philosophy RBA’s philosophy on green infrastructure is to focus on small discrete projects at the source of the pollution instead of large capital projects. Source controls express the underlying philosophy that it is more cost-effective to prevent pollution than to treat it. The effectiveness of a decentralized system depends upon the aggregate, cumulative effect of the many small-scale source control projects. The key to continuously reaping longterm benefits from these small systems is ongoing low-cost maintenance.

Port Richmond Industrial Development Enterprise Philadelphia, PA


The City of Philadelphia is investing heavily in green stormwater infrastructure, having transitioned to a billing system that assesses properties a stormwater fee based on impervious coverage. At the same time, the Philadelphia Water Department (PWD) has been experimenting with various other approaches to reduce stormwater runoff into the combined sewer system. RBA planners and engineers participated in a PWD study to examine how stormwater might be managed more collectively as opposed to on an individual parcel by parcel basis. This study involved the Port Richmond Industrial Development Enterprise, a business improvement district in Northeast Philadelphia that is home to a mix of industrial and commercial businesses. RBA identified a series of conceptual green stormwater infrastructure projects, developed estimates for costs per acre, and calculated the amount of “greened acres.�


Delaware River Trail Philadelphia, PA The Delaware River Waterfront Corporation (DRWC) is a nonprofit corporation that designs, develops and manages the central Delaware River waterfront in Philadelphia between Allegheny and Oregon Avenues. DRWC aims to transform the central Delaware River waterfront into a vibrant destination location for recreational, cultural, and commercial activities for residents and visitors of Philadelphia. RBA has completed conceptual design plans for the Delaware River Trail from Mifflin Street to Lehigh Avenue along Delaware Avenue/Columbus Boulevard and is currently undertaking final design. Work includes designs for the entire trail, which will incorporate sustainable design features and green infrastructure. RBA completed final design for the first part of the Delaware River Trail: the Penn Street section, which runs from Spring Garden Street to the Sugarhouse Casino. The Penn Street Trail, which is now open, features a continuous rain garden that captures and treats stormwater runoff that would flow into the city’s combined sewer system. The trail also features solar-powered lighting.

Spence School Green Roof New York, NY


The Spence School is a private all-girls school on the Upper East Side of Manhattan. The school is undergoing major renovations to update their existing infrastructure and achieve LEED Gold status from the USGBC. RBA prepared a feasibility study for the school on the installation of a green roof on their new facility. Based on the feasibility study The Spence School decided to incorporate a green roof into the renovation. RBA developed construction documentation (plans, specifications, and estimates) for the construction of the green roof. The green roof includes both extensive and intensive green roof areas, as well as outdoor seating with custom built planters and furniture. RBA also assisted in the design for an outdoor teaching classroom with custom designed planters and furniture. RBA worked in partnership with school staff and student committees, who were involved in selecting plant material for the green roof. RBA also provide further assistance to the school during installation.

Redesign of Bryan Park New York, NY As part of the New York City’s PlaNYC Plaza program, RBA redesigned an existing underutilized park located at the intersection of Fordham and Kingsbridge Roads in the Bronx. RBA redesigned the park with sensitivity to preserve existing trees, providing an array of public amenities centered on the creation of a new sustainable bi-level park/plaza space. The proposed design combines both the impervious park plaza and a stretch of under-utilized asphalt roadway to double the size of the park. The entire area was paved with a combination of permeable pavers, rain gardens, and large tree pits. The project is currently under construction and when complete will be the first plaza built under the NYCDOT Plaza Program where 100% of the plaza is converted to a pervious surface.
