Action Items

Implementation Of The Stormwater Master Plan

To meet the goals identified in the Plan, seven projects of varying scale and costs have been identified for implementation. Each project is identified as an Area of Concern contributing to the localized campus flooding, The projects are not dependent on each other, but all contribute to improved water management. Strawbery Banke staff must now prioritize and select the first project(s) to be advanced and implemented. Upon the selection of the priority projects the following step would need to be taken for the implementation of one or move projects:

• Further explore the feasibility of the prioritized project sites, which may include the following:

• Soil borings, sampling and testing to identify any potential challenges related to groundwater, infiltration, soil disposal or archaeological issues

• Develop Schematic (30%) design level plans, details and cost estimates.

• Internal review and discussion with the Strawbery Banke stakeholders

• Continue collaboration with the City and the identified permitting agencies.

• Develop 60% design level plans, details and cost estimates.

• Submit plans and documentation for the necessary permitting.

• Develop construction documents and final cost estimates for bid and construction.

Both private and public grant opportunities should also be explored for full or partial funding of the projects.

Resiliency Planning

Beyond the goals of this Plan, Strawbery Banke will move towards becoming a model for a resilient coastal campus that embraces both structural and naturebased solutions to better manage stormwater and address the long-term effects of sea level rise. This will require the Strawbery Banke staff to continue and expand upon their planning efforts. The next step to move Strawbery Banke towards becoming a model resilient coastal campus and adapt to the pressures of climate change is to develop a campus wide Climate Change Action Plan to address the following:

• Sea level rise and storm surge inundation.

• Groundwater rise and basement flooding

• Transition towards using sustainable materials

• Assess energy use and conversion to renewables

This will require continued collaboration with the City of Portsmouth to address the larger challenges facing the campus, which includes:

• The impacts of sea levels rise on the city storm drain outlet located within the Strawbery Banke Campus.

• The localized flooding of Marcy Street and the overflow of stormwater from larger storm event from the Strawbery Banke Campus

• The impacts of the proposed improvements/changes to Prescott Park and their impacts on the Strawbery Banke Campus.

Move Towards A Resilient Campus

The ultimate goal is to protect the historic assets from rising waters and continue to offer a rich museum experience to visitors by addressing the impacts of both localized flooding and long-term sea level rise. In order to meet this goal, Strawbery Banke will move towards becoming a model for a resilient coastal campus by committing the necessary resources to the following:

• Develop a culture of sustainability and stewardship of natural resources.

• Update the Stormwater Master Plan and continue to implement GSI techniques within the campus, beyond the projects identified in the Plan, such as rain water harvesting and re-use.

• Increase the % Tree Canopy Cover across the campus.

• Honor the past through material use, native plantings, and water reuse.

• Reduce the carbon footprint through the use of renewable energy

• Serve as a resource for education and outreach.

• Improve campus resiliency

• Continue coordination with our neighbors, community organizations, academic institutions and local, state and federal agencies.

• Address basement flooding and groundwater rise.

• Adapt the campus to storm surge inundation.

Strawbery Banke Museum will become an ever more visible model of a resilient and thriving coastal campus for years to come.
