sustainable site features

For the MITRE 4 office development in Tysons Corner Virginia, Elizabeth prepared detailed grading and detailing as part of the Pennoni design team within an overall multi-disciplinary team that included Jordan Honeyman Landscape Architecture.  Sustainable site features include planters that provide stormwater management (SWM), and permeable paving.

rain gardens

 For the design of many rain gardens and SWM wet ponds, Elizabeth proposes native plants that will allow for seasonal color and variation.  Elizabeth was a lead designer with Pennoni for the landscape design shown here for an Arlington, Virginia rain garden.  Here, indigenous plants, such as coneflower, rudbekia, liatris, and native grasses create masses of color and attract butterflies to this rain garden in a residential neighborhood.

other grading & drainage solutions

During her more than 30 years experience in site design with multi-disciplinary civil engineering firms and a large architectural firm, Elizabeth developed proven skills in detailed site grading and design of solutions to drainage issues.  Depending on site and overall design concept, drainage solutions may include surface drainage redesign, an infiltration French drain, or a naturalistic dry-stream.
