Landscape Architecture, Ecological Restoration and Planning


It's In the Details

Planning and Designing the finest landscapes and outdoor garden rooms is important to us at SED Design, but it is the 'art of detailing' and the way materials are joined that bring a space to life.  From concept to finished details, let us help you imagine how to transform your landscape to better serve you.

Landscape Management Plans


For Natural Area and Traditional Landscapes

Landscape Management Plans prepared by SED Design guide your site’s management with cost effective and environmentally sound techniques.  Our Landscape Management Plans are designed to enhance the value of your property and quality of your landscapes.  We work closely with our clients to address both their immediate needs as well as the long term care for maintaining sustainable landscapes.   Our management plans utilize Plant Health Care (PHC) programs and Ecological Management strategies for traditional landscapes with discriminating requirements and natural areas, like meadows, woodlands and wetlands to enhance the environmental value of your site.



Woodlands, an important part of many regional landscapes, are composed of many different plant communities including many diverse species.   Woodlands require unique planning to maintain their quality and health. Woodlands are often compromised by aggressive non native species. In many situations these invasive species displace preferred native plants. Management plans by SED Design consider the reproductive strategies of each plant to create the best management plan. Replanting with appropriate native species, specific to the individual community, plays an important role in the long term stability of the woodlands.



Meadows are herbaceous communities of wildflowers and grasses. When properly managed, these open landscapes offer tremendous wildlife habitat.   The reduced maintenance cost of meadows over traditional landscapes makes meadows an important tool in designing cost effective management plans. Quality management plans for meadows recognize the importance of the establishment period as well as long term techniques required to sustain a balanced ecosystem.



Wetlands ranging from Riverine systems, such as perennial streams and smaller ephemeral swales, to Palustrine wetlands, such as floodplains and wet meadows, require special understanding and care. Wetlands are often compromised by changing hydrology in the area particularly due to increased runoff and erosion. Management planning by SED Design includes studying the local hydrology to create stable wetlands that mimic natural ecological functions.



Arboriculture plans recognize that trees in the landscape add significant social and ecological benefits and value to the property. Our management plans anticipate the long term replacement of trees as well as their immediate care in order to maintain the character of the landscape that trees so importantly define.

SITES™ Certification


Sustainable SITES™

Commissioning Services


SITES™ is the leading environmental stewardship certification program to preserve and enhance the ecological functions of our built landscapes. SITES™ is sponsored jointly by the ASLA, the Ladybird Johnson Wildflower Center and the United States Botanic Garden.


SITES™ standards will protect and enhance our natural resources including air, soil and water as well as the cultural and aesthetic quality of the landscapes in which we live.


SED Design is proud to be participating in the Sustainable SITES™ initiative and is able to provide the leadership to assist you and your organization in achieving SITES™ certification.


Our knowledge of the SITES™ program makes SED Design the right choice to prepare the documentation required to achieve your SITES™ certification.
