Our Environmental Design services include designing stormwater management and sediment and erosion control plans to protect our waterways and downstream ecosystems. Our engineers also perform noise and air quality analyses to help our clients minimize effects of transportation projects on surrounding communities. We specialize in many types of design and analysis, including:
Managing stormwater in an aviation setting is always challenging. Providing stormwater management for BWI Airport is a special challenge because 13 streams originate within the airport property. Our experts developed a comprehensive stormwater management plan based on the data we gathered and the goals we established.
The Maryland-National Capitol Park and Planning Commission proposed the creation of a community park in Germantown, Maryland. The property included sensitive emergent wetland systems. Our concept for stormwater management design allowed the wetlands to transport stormwater flows in a stable manner, reduce downstream sedimentation, and eliminate the need for costly grading, while meeting the community’s need for active recreation.
GSA’s re-development of the former Saint Elizabeth’s hospital into a high security campus for federal agency tenants in Washington, DC required a thorough analysis of noise pollution and air quality during concept development stages. SES provided these services to GSA to help them assess the effects on surrounding communities. Sachs Branch Stream Restoration Design
Maryland Department of the Environment (MDE) and US Army Corps of Engineers issued permits to the Maryland Aviation Administration to impact waters of the US and wetlands to for construction of the Midfield Cargo Complex at Baltimore/Washington International Thurgood Marshall (BWI) Airport. SES completed a geomorphic assessment, natural channel design and environmental monitoring of the restoration construction for Sachs Branch as partial mitigation for these impacts.
Anne Arundel County constructed a new connector roadway to improve traffic circulation and reduce congestion. SES delineated the resources, worked with engineers to avoid and minimize impacts, and designed a stream restoration to mitigate unavoidable impacts. The restoration of the Western Tributary to Church Creek transformed a rip rap lined channel into a natural riffle-pool sequence and meander pattern that would improve in-stream habitat conditions and sediment transport.
