Natural Systems Help Us: Rowley salt marsh
• recreation• shellfishing• scenic character• storm
protection • floodwater
storage• carbon
sequestration
Current Adaptation Activities:
Strategic Land Conservation
Regional Partnerships
Nelson Island,Parker River National Wildlife Refuge
road closure and retreat
Continue acquisition of land to allow for salt marsh migration if/when available
Increase resiliency of marsh and river systems by removing debris, assessing culverts, supporting natural drainage of water, removing Jewell Mill dam
Monitor flood frequency and depth and create early warning system to alert residents when roads are likely to be flooded.
Coordinate with evacuation planning for major storms. Need an alternate/primary evacuation route (Route 1).
Ultimately further retreat may be needed and buyout of Stackyard Rd and other low-lying homes.

2016 CZM Resiliency Grant awarded to Town of Ipswich for study of river bank erosion & future climate impacts
Downtown Ipswich
• Downtown business owner engagement and education on building retrofits and general principles of resiliency
• Ipswich Mills Dam Removal Feasibility Study will analyze the effects of removing the downtown dam, including downstream impacts and opportunities to restore upstream flood storage capacity
• Encourage green infrastructure for stormwater and floodplain mitigation (i.e. rain gardens, pervious walkways & parking areas, infiltration trenches, and other best management practices)
• Create and enhance riparian buffer along the Ipswich River up and downstream of Town
• Consider river bypass through Veteran's Green/Elm St. area to accommodate 500-year flood

Current Adaptation Activities
• Causeway reconstruction in 2012
• Emergency vehicles are stationed on the East side of the Causeway when flooding is expected
Main Street Causeway
• Engage business owners collectively on resiliency planning• Develop additional emergency monitoring policies &
practices such as a live video feed showing if the Causeway is flooded or impassable
• Encourage best management practices for floodplain mitigation (i.e. rain gardens, pervious pavement for parking lots and walkways, and other green infrastructure techniques)
• Convene Essex Causeway Working Group to begin resiliency planning for both short-term and long-term impacts (include local business owners, state agencies, and town representatives)
• Beneficial Use of Dredged Materials from the Essex River
