Research Paper: Response to Stream Restoration in an Agricultural Watershed
This multi-year study of the USGS shows that natural, soft engineering techniques installed by Pennsylvania and local partners are delivering results. Several stream restoration practices have "significantly reduced streambank erosion, boosted floodplain sediment deposition, and improved overall stream health in an impaired agricultural watershed." Key outcomes:

  *   Stream restoration changed streambank sediment flux from erosional to depositional.
  *   Restoration increased floodplain deposition the most in smaller headwaters.
  *   Stream restoration resulted in a seven-fold increase in net sediment retention.
  *   Digital elevation models produced from drone-acquired data improved assessments.
These DEP-supported restoration efforts not only improved water quality but also contributed to delisting portions of Turtle Creek from the Clean Water Act 303(d) impaired waters list - a major milestone for local ecosystems and for Chesapeake Bay watershed recovery goals.

Research Paper: Green Infrastructure Maintenance in the Chesapeake Bay Watershed
A group of Chesapeake Bay NGOs recently released a white paper that focuses on green stormwater infrastructure (GSI) maintenance in the Chesapeake Bay watershed. Specifically, the white paper focuses on:

  *   Investigating the current status of GSI maintenance
  *   Identifying key themes about GSI maintenance
  *   Providing constructive and useful guidance to assist with challenges
Intended audiences include local government stormwater staff, contractors that perform GSI work on public and private properties, NGOs that intersect with GSI as a partner with other entities, and other practitioners that have a role in GSI maintenance (e.g., HOA or commercial property managers).
