Concrete slab becomes ASLA Award-winning urban oasis
For more than 45 years, a one-acre expanse of concrete in Southeast Philadelphia sat at the edge of the Delaware River, empty and forgotten. With an ecologically minded design strategy, we helped the Delaware River Waterfront Corporation transform this vacant lot into Washington Avenue Green, an engaging, evolving riparian ecosystem and community amenity.
The design generates and increases biodiversity in the locale by establishing a seed bank in the new soil, and a node from which native plants can migrate. Working with environmental artist Stacy Levy, we created concrete and asphalt ‘dendridic decay’ gardens that allow native plant species to accelerate decay processes and reclaim the space while adding habitat and stormwater retention and filtration. Concrete salvaged from the site is reused as a seating/retaining wall and as elements in a native ‘rubble’ meadow. Community groups played an active role in the creation of the waterfront park by participating in visioning sessions and watershed workshops. They built a series of floating wetlands that were then tethered to the old pier structure to provide new habitat for aquatic wildlife in the Delaware River.
We’re thrilled to announce that the project was selected as a 2013 Potomac and Maryland Chapter Merit Award winner. The Southern California Chapter of the ASLA, which juried this year’s submissions, determined that the project exhibited a level of excellence that set it apart from others. The design team, snapped at the ribbon cutting last year, includes (L to R) Ed Morgereth (Biohabitats), Jennifer Dowdell (Biohabitats), Stacy Levy (Sere Ltd.), Adam Ganser (Biohabitats) and Joe Forkin (Delaware River Waterfront Corporation).
Swimming through navigation channel = running the gauntlet
If you’ve ever driven through rough weather along a long stretch of highway with no rest stops, you have some sense of what it must be like to be a juvenile yellow perch swimming through Cleveland, Ohio’s Cuyahoga River Navigation Channel. Bustling with barge traffic, oxygen depleted, and lined by bulkheads for five miles, the channel can be a challenging place for a fish seeking food or protection from predators. This lack of habitat is common throughout major navigation channels in many Great Lakes cities.
Since 2006, the Buffalo District of the U.S. Army Corps of Engineers has been developing, testing and implementing innovative bulkheads and technologies to create habitat for larval fish while maintaining the channel or navigation. Building on the lessons learned through that process, but applying a new, biomimicry approach, Biohabitats is working with the Cuyahoga County Planning Commission on the third phase of this “Green Bulkhead Project.” In this phase, we are looking to nature for inspiration and design guidance. Our team, which includes biomimicry experts Taryn Mead and Barry Patterson, Ocean & Coastal Consultants, Ecocean and fisheries biologist Dr. Jeffrey Miner, is eager to build on previous efforts and join forces to create much needed fish rest stops along the Cuyahoga.
Speaking of green bulkheads…Biohabitats has been working with seniors from the University of Maryland’s Environmental Science and Technology program who have chosen to develop and test different types of living facades that can be affixed to hardscape bulkheads as their capstone project. The students have deployed one of their test green bulkheads at the Living Classrooms Foundation’s facility in Baltimore’s Inner Harbor. We look forward to monitoring the students’ work and applying what we learn to our work in urban waterfronts!
Stream restoration improves campus “life”
On many college campuses, spring is a busy season for intramural sports. The University of Virginia is no exception. Soccer, kickball, and ultimate Frisbee are just some to the activities that bring the Charlottesville campus to life as the weather warms. But a degraded stream that was eroding away some popular athletic fields was threatening to impact that aspect of UVA campus life. Recognizing the opportunity to restore the stream, a tributary to Meadow Creek, and protect the athletic fields, the University turned to Biohabitats. Our design relocates the stream so that it has a larger flow area, more stability, better habitat and improved water quality. The restoration will also replace mown lawn with native riparian vegetation. Construction is nearly complete, and plantings will be in place next month. This restoration, located downstream of two previous stream daylighting and restoration projects we undertook for the University, adds to the overall health of the Meadow Creek ecosystem, and the beauty and function of the campus’ green infrastructure. That’s nothing to be Cavalier about!
Restored stream regenerating habitat, groundwater & more
We love seeing our designs come to life, and last month, we got to do just that as construction wrapped up on the restoration of a degraded tributary network in suburban Crofton, Maryland. Before the restoration, severe bank erosion and channel incision into loose Coastal Plain deposits were threatening infrastructure in an adjacent residential community. Moreover, channel incision resulted in a drawdown of the groundwater table, which changed the plant community, and degraded water quality, and aquatic habitat. Working with the Anne Arundel County Department of Public Works, we crafted a design which better connects the channel to its floodplain, restores watershed processes (including groundwater recharge), eliminates high and eroding banks, improves water quality and will result in conditions favorable for native Coastal Plain biota. The restored stream will only continue improving as more plants are installed in the coming weeks.
From Refuse to Refuge
Once the world’s largest landfill, the former Fresh Kills landfill on New York City’s Staten Island is now the site of one of the most ambitious public works projects ever undertaken. Combining state-of-the-art ecological restoration with extraordinary settings for recreation, public art, and sports, the City is transforming the 2,200-acre landfill into a public destination known as Freshkills Park. Earlier this month, the transformation officially began as ground was broken for the first pilot project on the site, the North Park wetland restoration.
With support of a grant from the New York Department of State’s Office of Coastal, Local Government & Community Sustainability, Biohabitats is helping New York City’s Department of Parks & Recreation restore two acres of salt marsh and coastal grassland habitat. A variety of restoration techniques are being tested, including the use of mussels to create a stable, ‘living’ shoreline that will be resilient in the face of climate change and sea level rise; and the use of goats as a pesticide-free and potentially job-creating method to help control invasive Phragmites. This pilot project will guide future, larger wetland restoration projects within the Park by determining successful and cost effective measures for restoring tidal marsh.

People
Jessica Hardesty Norris, Technical Writer
Newly transplanted to South Carolina, Jessica Hardesty Norris recently joined our proposal team as a Technical Writer. She spent a decade living in and traveling to South America, first as a Peace Corps Volunteer, then as a researcher completing her PhD in avian ecology at Duke, and most recently as the director of a seabird conservation program, which she led into 10-fold growth through grant writing and fundraising. Working on island restorations for seabirds ignited her interest in restoration, so she lurked around Biohabitats website and pestered Keith until they hired her. Now she is happy to be helping the technical staff bring together proposals, and also to be sticking closer to home and her (soon-to-be three) young daughters.
Scott Pullen, Construction Project Manager
Many little boys dream winning the World Series. For landscape architect Scott Pullen, this dream was realized at age 10, when, as starting right fielder for the Columbus Bruins, he helped his team win the Little League World Series. These days, Scott is immersed in what you might call the World Series of Stormwater Retrofits. As Biohabitats’ Construction Project Manager, Scott is helping Montgomery County, Maryland retrofit more than 4,000 acres of impervious surface over the next three to five years in order to comply with their Municipal Separate Storm Sewer System (MS4) permit, one of the most stringent in the nation. With his 16 years of experience in landscape design, construction and management and a self-professed need to keep his hands in the dirt, Scott is ideally suited to this work. In fact, his commitment to water quality is about the only thing in his life that equals his passion for The Ohio State University (his alma mater) sports. Though Scott’s career as a right fielder ended in little league, we’re quite certain he’s in the right field with us!
