The projects listed here, although found elsewhere on MassDEP’s website, demonstrate the depth and breadth of projects resulting from this collaborative effort.

• Massachusetts’ Valuable Coastal Floodplains – An Outreach Initiative – 2021- 2022 WPDG
  
  Project Description, Objectives and Tasks: This grant was recently awarded to MassDEP in Summer 2021. In preparation for and to support the upcoming wetlands regulation revisions that will incorporate new performance standards for Land Subject to Coastal Storm Flowage (LSCSF), also known as the coastal floodplain, and to enable better public understanding of the purpose and goals of protecting that wetlands resource area, MassDEP will produce an outreach-curriculum package focused on reaching a wide public audience. The outreach deliverables will be facilitated by specialists in GIS and Marketing overseen by MassDEP and MCZM staff.
  
  The project tasks and products consist of three interrelated components that will include GIS/ESRI StoryMap showcasing up to six MA coastal floodplain locations in developed, semi-developed, and undeveloped areas, with photographs, including some from before and after past storm events that show the impacts to structures, infrastructure, and natural landforms, for each location. In addition, brochures and infographics will be produced that describe coastal floodplain functions and how they support storm damage prevention, flood control and the state’s climate resiliency effort (e.g., “Rules of Thumb for Protecting the Coastal Floodplain”).

• Facilitating River and Stream Crossings Improvements in Massachusetts - 2019-20 WPDG
  
  Project Description, Objectives and Tasks: This grant is scheduled to be completed in 2022. It involves the development of tools that will help facilitate wetland permitting of river and stream crossing replacement projects to improve aquatic organism passage (AOP) for fish and wildlife statewide and promote resiliency for future flood flows. Many roadway crossings of rivers and streams in Massachusetts are undersized resulting in substantial impacts to fish and wildlife movement and to the survival of organisms and their populations. Additionally, undersized structures lack the resiliency needed to withstand large floods and potential changes in flood flows.  This grant is a partnership between MassDEP, USGS, and UMass-Amherst.
  
  There are two projects within this grant: 1) development of a simple guidance for local and state regulating authorities and applicants that will facilitate wetland permitting of river and stream crossing replacements that improve fish and wildlife passage and explain how to apply the wetlands regulations; 2) examine the feasibility of creating an easy to use web-based tool that includes a statewide hydraulic model to determine the optimal replacement crossing structure size that balances maximum habitat connectivity, structural resiliency, and minimizing negative impacts from downstream flooding and property damage. Work completed thus far includes multiple briefings and progress towards the final deliverables. UMass is responsible for Project 1 to develop a simple guidance and is working to finalize that document. The final submittal is expected to be submitted to EPA no later than September 2022. USGS is finalizing the feasibility analysis that supported moving forward with the project. The final deliverable is expected to be complete by June 2022.
  
  Following the presentation of results, a concurrent but separately funded task began that includes development of a prototype web based hydraulic tool for a pilot basin. This tool is intended to assist applicants with sizing culverts to be resilient and meet aquatic organism passage standards to the maximum extent practicable. This pilot is scheduled to be completed by June 30, 2022.
