This document is a Technical Memorandum from Environmental Research Group (ERG) to the Smithsonian Institution (SI) regarding Stormwater Best Management Practices (BMPs) and Post-Construction Considerations for a proposed solar array at the Smithsonian Environmental Research Center (SERC) in Maryland.

• Meeting Date: April 29, 2025
• Project: Addition of a solar array at SERC near Edgewater, Maryland.
• Location: Existing forested area near Woodlawn House.
• Impact: Only the solar panel design and base will increase impervious areas and runoff coefficients.
• Stormwater Requirements: Discusses applicable stormwater requirements, including Maryland Department of the Environment (MDE) recommendations for BMPs for solar arrays.
• Site Conditions: Evaluates four potential sites based on slope and soil composition. All identified sites have slopes over 10%, requiring structural terraces or berms.
• Recommendations:
  • Non-structural methods promoting disconnection of impervious cover are preferred.
  • For slopes < 5%, a disconnection flow path equal to or greater than the solar panel width is required.
  • For slopes between 5-10%, additional BMPs like level spreaders are needed.
  • For slopes > 10%, terraces or berms may be required.
• Permitting: Requires approval from MDE and Anne Arundel County, including NPDES permit with SWPPP and Erosion and Sediment Control Plan.
• Attachments Referenced: Includes MDE guidance documents, technical memorandums, and soil survey data.

This document provides critical information regarding the environmental considerations, specifically stormwater management, for the proposed solar array project. Bidders should understand the site's topographical and soil conditions, the required stormwater management practices (BMPs), and the regulatory requirements (MDE, Anne Arundel County) that will influence project design and implementation. This information is essential for developing accurate proposals and understanding potential project constraints and costs related to environmental compliance.
