Landscape Architecture, Ecological Restoration and Planning
SITES™ Pilot Project - The Taylor Residence
SED Design was proud to work with Margot Taylor, RLA, Owner of Land Ethics. The Design is one of three in the country that was able to earn 3 of 4 stars in the SITES™ rating system. Most simply stated, SITES™ is the landscapes response to LEED which primarily focuses on the structure rather than the site. The program is demanding and shows great promise in becoming the new standard in responsible landscape design and construction.

Sustainable Wetland Garden
The garden sits in the Universities Arboretum as a demonstration of environmentally sensitive design. It showcases an example of form extracted from function, minimizing impacts on the local and regional watersheds. An aerial aquaduct conveys roof run-off to a wetland bio-filter, where it is combined with surrounding stormwater, which then in turn is cleansed by plants with this proven purpose of bioremediation. As an expression of form, the aquaduct is power by a solar photovoltaic panel which pumps the water through the aquaduct making it an aesthetic feature in the garden when it is not serving it main purpose of conveying rainwater.

The Hillside Terrace
The Hillside Garden created by SED Design is a feature project in a film on creating sustainable landscapes.
The outdoor living spaces are terraced on a hillside outside of Philadelphia overlooking the Whitemarsh Valley. The design is a model for managing stormwater in creative ways that engage people while cleansing our water supply and recharging our aquifers. Rain water is captured in a garden runnel that flows through the garden wall and cascades into the water garden below. Overflow then flows through the vegetated swale and infiltrates into the soil below where it is filtered and cleansed by the roots and microbes contained in the soil.

This rain garden embraces storm water run-off. Rather than taking it away from the site through conduit, that water becomes a pleasing feature in the garden. Rainwater from nearby impermeable surfaces and gutters all gather in these swales. In the event of heavy rainfall the run off will make its way to a natural spring.
The Bioswale at Neptune Elementary School handles rainwater runoff from the parking lot. This is beneficial for plants, animals and people. By allowing storm water to saturate the ground rather than speed over impervious surfaces and through miles of piping, mass flooding can be reduced. The plants chosen for the Bioswale are chosen specifically for the site to be hardy enough to sit in flood conditions or endure a mid summer drought. The design of the Bioswale allows refuge and food for wildlife. Being on a school campus it also has the benefit of teaching all this to the children and community.

Community Trail Network
Situated adjacent to the Summerfield School, SummerWood is an educational resource that is integrated into the school curriculum. The site was under constant stress from invasive species. SED helped design a plan that would help beautify a struggling ecosystem. The trail system not only creates a place for people to move through and become connected, but it raises awareness of this valuable open space, helping preserve it for generations to come.

First Order Stream
This ephemeral 1st order stream restoration has created beneficial habitat. Through excavation of a new stream channel the previous piped stream was ‘daylighted’. A stone and cobble substrate was established to stabilize the streambed and gentle side slopes were planted with native species for streambank stabilization.
Clear Well Meadow Rehabilitation
At Philadelphia's Baxter Water Treatment Plant, a meadow installation protects 65 acres of underground, clear-water storage vaults. It also benefits stormwater management, wildlife habitat, and biodiversity along the Delaware River and Delaware Estuary Complex.
At this site, a 35-year history of inattention allowed heavyweight, woody vegetation to become established. This vegetation, much of it invasive, was compromising the structural integrity of the vaults, making a lightweight cover essential.
SED Design developed a meadow plant community concept, an implementation strategy and an ongoing management strategy for the Philadelphia Water Department. Selected native warm-season grasses and wildflowers are adapted to the site conditions and provide superior natural value and reduced maintenance costs compared to the turf alternative. Because of drinking water concerns, the implementation and ongoing management plans succeed without the use of herbicides.
This lightweight meadow implementation effectively protects the vaults while providing economic, ecological and aesthetic benefits.
Meadow and Reforestation
The Urban Meadow and Naturalization at the Bureau of Laboratory Services of the Philadelphia Water Department is a unique native restoration of an urban lot. The project includes a sweeping open meadow and borders of native tree and shrub communities that represent the succession of our native landscape. The project provides a natural oasis in the urban landscape and educational opportunities for the local schools and community.
Boeing Green Roof Garden
The Green Roof Garden for the Boeing Corporation in St. Louis serves as an entrance plaza above underground portions of the building complex. The green roof transforms this important entry and public gathering place from a concrete slab to a place of aesthetic and environmental value.
A rich garden setting is created by gently deepening the green roof growth media as it moves out from the walk. This strategy provides opportunities for greater plant diversity. While the plants bring beauty and life to this previously sterile environment, they also absorb, filter and cool storm water runoff.
Recalling the context of the site, the serpentine entrance walk reflects the meandering Mississippi River, while the grid of the plaza paving reflects the urban and agrarian setting through which the river “flows.” Seating kiosks perform also serve as light wells to allow natural light to enter underground portions of the building.
The Green Roof Garden successfully converts a concrete slab into a place where stormwater is mitigated while employees and visitors enjoy the benefits of the outdoors.
Educational Green Roof
The Neptune Midtown Community School Educational Green Roof Rooftop Garden, designed by S. Edgar David and Associates, is part of a platinum LEED building and the first green roof for the New Jersey School system. Each element of the school and the green roof garden is designed to be a teaching tool integrated with the school curriculum. The school, designed by SSP Architects, and green roof rooftop garden teach children principles of sustainable design and conservation through personal experience. By generating an awareness of environmentally beneficial opportunities through positive experiences children are empowered to shape their future.

PECO Rooftop Garden
The PECO rooftop garden in Philadelphia is a landmark urban green roof project demonstrating all the benefits of this unique technology. SED Design worked in collaboration with Roofmeadow on the planting design and plant specification.
