• 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.
