New Hampshire’s coastal waters have significant ecological, commercial, cultural, and recreational values for the state and its citizens, but the coastal waters are showing signs of pollution and environmental decline. Recognizing that water issues cannot be solved without collaboration, the New Hampshire Legislature created the Southeast Watershed Alliance in 2009. The Alliance is a means for communities to address water pollution, water supply, wastewater and stormwater management, septic systems, land use, and conservation.
The Southeast Watershed Alliance encompasses all forty-two New Hampshire communities in the New Hampshire coastal watershed. The Alliance is committed to improving the waters through collaborative watershed studies, education, and project implementation.

|The next SWA quarterly meeting will be held February 4, 2015 beginning at 6:30 at the Lee Public Safety Building, 20 George Bennett Road. Topics will include a summary of recent research on non-point sources of nitrogen to Great Bay, SWA funding and SB229-FN-A, and impacts in the Oyster River watershed if SWA stormwater model ordinances were to be adopted.
The Senate Energy & Natural Resources Committee is conducting a hearing on Senate Bill SB229-FN-A on Wednesday, January 28, 2015 at 9:30 A.M. in room SH 100 in Concord. This bill will appropriate $200,000 in FY 2016 and another $200,000 for FY 2017 to the NHDES for the purpose of developing a Watershed Management and Restoration Plan for the waters of the Southeast Watershed in accordance with EPA guidelines. The bill authorizes the NHDES to pay this money to the Southeast Watershed Alliance contingent upon a matching amount (which can include in-kind support) from the municipalities located in the watershed. SWA representatives are encouraged to attend to voice support. Click the link to view the bill: SB229-FN-A, 2015, funding for SWA & creation of watershed mgt plan.
SWA Quarterly Meeting Oct. 15, 2014 6:30 at the McConnell Center, 61 Locust Street, Room 306, Dover. Learn about SB 60, a means to create a state trust fund for drinking water, stormwater, waste water, and dam infrastructure. Board of Directors will meet at 5:30.
The Final Great Bay Nutrients Peer Review Report is now available.
The Seacoast Coalition and NHDES have reached a settlement in the lawsuit over the establishment of nitrogen criteria for Great Bay. Read the settlement letter here.
SWA has sign templates available for bioretention systems, tree filters, and gravel wetlands. Inform citizens about these effective stormwater treatment systems. Contact SWA to customize your sponsors’ logos.

The Southeast Watershed Alliance has prepared draft stormwater management standards to provide a consistent and effective level of stormwater management and protection of clean water within the NH coastal watershed. These model standards are under consideration by several communities and have already been adopted by the Town of Newfields.
This project provides assistance to communities to improve stormwater management through the expertise of engineering consultants, installation of demonstration stormwater treatment systems, and workshops and outreach to municipal employees, town officials, volunteers, and neighborhood residents. For more information, contact Alison Watts, SWA project coordinator, at email@example.com.
This project improved stormwater management in selected communities. First, project leaders identified and mapped Locations appropriate for the installation of stormwater treatment systems. Results included engineering consultation and design, soil mix and planting recommendations, and installation oversight and training. Projects included bioretention systems, gravel wetlands, and a tree filters. These systems treat stormwater run-off on-site and reduce pollutants discharged to waterways. Communities also received a GIS-based pollutant loading map to identify locations for future stormwater treatment installations.
