1. First Steps and Community Dialogue Liz Moran Ph.D. Linda Wagenet Ph.D. Nate Weeks P.E. August 18, 2011

2. Project Assignment Find effective strategies to protect and restore kettle ponds for their desired uses- now and in the future Develop specific, targeted recommendations for community consideration

3. Topics of Discussion Introduction – Pond Evaluations in the context of comprehensive water and wastewater planning Overview of Approach and Timetable Current Conditions – Preliminary Results Desired Future – Opportunity for Comment Need for Action Next Steps and How to Stay Involved

4. Project Team EcoLogic LLC Liz Moran Linda Wagenet Kurt Jirka and Kerry Thurston GHD Nate Weeks

5. Project Schedule Compile existing data and information July- Aug. 2011 Identify and address gaps – field sampling program Aug. 2011 Gather local input on impairments and priorities- Aug. 2011 Prepare Draft and Final Action Plan- Sept.- Nov. 2011 Complete plans, permits and budgets for any remedial measures Dec. 2011- March 2012 Implement first phase - Target --Summer 2012

6. Setting the Context Comprehensive water and wastewater management planning Focus on Human and Environmental Health Nitrogen and Phosphorus impacts on coastal embayments and inland kettle ponds

7. 1. Where are we now? Descriptive Information, Community Values 2. Where are we going? Trend Information, Probable Scenario 3. Where do we want to be? Possible/ Preferred Scenarios, Community Vision 4. How do we get there? Goals, Strategies, Actions, Action Agendas & Priorities Framework for the Eastham Ponds Action Plan Based on: Ames, Steven C. Community Visioning: Planning for the Future in Oregon’s Local Communities. American Planning Association National Conference Proceedings, San Diego CA 1997.

17. Where are we going? Tools for predicting future conditions- more phosphorus, more plant and algal growth Reduced recreational opportunities, aesthetics, fisheries

18. Reactions? Have you been seeing these same changing conditions- how are local use and enjoyment affected?

20. Criteria to Set Remedial Priorities Matrix of protection and restoration alternatives Technical feasibility – track record on Cape Cod Longevity of solution Relative cost and environmental benefit Priority ponds Extent of use impairment Outlook for future- water and phosphorus models Public access Community desires and commitment Others?

21. Next Steps and How to Stay Involved Focused timetable – opportunities to comment Draft work products posted on Town web site Pond associations

22. Alum effectiveness Stable stratification TP limited, algae impair uses Internal TP release significant fraction of budget Long water residence time
