Floura Teeter is the Landscape Architect and Arborist for the project responsible for planting design for approach roadways and associated improvements on both the Virginia and Maryland sides of a new bridge across the Potomac River. Services include analysis of forest impacts, recommendations for avoidance and minimization techniques to preserve forest resources, and planting design for new plant communities to reclaim disturbed areas of the site located within Maryland’s critical area and Dahlgren Wayside Park in Virginia.

Planting Approach

Proposed plantings within the critical area include only species native to the Maryland Coastal Region. Planting design is sensitive to several functional factors including stabilizing areas within environmentally sensitive areas and the 100-year floodplain to minimize soil erosion and create habitat to support pollinators and wildlife, while satisfying mitigation requirements for permanent disturbance within the critical area and expanded buffer.

An outline of establishment and maintenance procedures for a two-year period are incorporated into plans and specifications to assist the contractor in achieving maximum plant survivability.
