Winthrop Beach Restoration project

Two Working Groups Addressing Winthrop Beach Restoration Project Environmental Assessment GroupSocio-economic Assessment Group WHAT? WHY? WHERE? WHO? WHEN?

Applying Coastal Management General Steps for Winthrop shoreline/beach restoration: 1.Resource assessments (environmental) – What type of assessments were done in the Winthrop beach restoration? Why? What environmental conditions are needed for beach to exist? 2. Impact assessments – for both the shoreline/beach that needs to be restored and for sites used for creating the beach! Use conflict analysis! Describe what was in conflict and why? 3. Policy and regulatory framework – which agencies and communities participated in decision making process? 4. Economic assessment – feasibility study 5. Implementation – what was in this case critical for making a decision(s) that was made? 6. Monitoring and evaluation – identify the best indicators (natural and socio- economic)

Winthrop Beach Restoration Project: environmental assessment and suitability indicators selection

Winthrop Beach Restoration Project socio-economic assessment and selection of criteria and indicators: Criteria and suitability indicators selection include: time frame; economic feasibility analysis; what’s the value of the beach? Policy analysis; review and amendments of related law & regulation; Agencies involved Community participation

Winthrop Beach Case Study - Joe Orfant from the Massachusetts Department of Conservation and Recreation (DCR) will summarize the history of Winthrop Beach including severe storm damage, construction of a seawall, breakwaters, and groins, and development of a recent proposal to nourish the beach with 500,000 cubic yards of sediment. - Winthrop is a barrier beach between two eroding drumlins. Five upland and 14 offshore sources were considered for the beach nourishment project. Upland sources were estimated to cost at least 2-3 times that of an offshore source using a hopper dredge. The preferred offshore option is the NOMES site 1, which is eight miles southeast of Winthrop and was identified by a study funded by the National Oceanic and Atmospheric Administration (NOAA) in the 1970s as a potential aggregate source. -12-month marine biological study was conducted for NOMES 1 and a biological impact assessment report was filed in December The permit process for this project began 7 years ago. During the permitting process, $500,000 has been spent on temporary reinforcement due to undermining of the seawall and the formation of a sinkhole landward of the wall. - DCR's goal is to have all of the permits by the end of this summer and put the construction project out for bid in early fall.
