  • City of Biddeford, Maine Open Space Plan
    City of Biddeford, Maine Open Space Plan Biddeford Pool Marshes & Wildlife Habitat Prepared by the City of Biddeford Open Space Committee November 2012 PREFACE When I was first asked to be on the Biddeford Open Space ad-hoc Committee by Marcel Polak of the Maine Association of Conservation Commissions on behalf of then, Mayor Joanne Twomey, I ĞŶƚŚƵƐŝĂƐƚŝĐĂůůLJƐĂŝĚ͞LJĞƐ͘͟ I was reasonably excited but cautiously optimistic. I have a very strong passion for land conservation and my knowledge of the subject is constantly evolving. After the introductions and brief conversations in our first meeting back in January 2009, the topic of the need for a chairperson came up. I now ƌĞĐĂůůĞǀĞƌLJďŽĚLJ͛ƐĞLJĞƐƚƵƌŶŝŶŐƚŽǁĂƌĚŵĞĂŶĚĂƐƚŚĞLJƐĂLJ͞ŝƚŝƐĂůů ŚŝƐƚŽƌLJ͘͟ I graciously accepted and the reality of taking charge of organization, delegation, research, setting meetings and pushing for a draft of the Open Space Plan took hold. Now, close to three years later, and countless number of meetings, walks, and drafts, we have an Open Space Plan for the citizens of Biddeford. As you read through this document, it is fluid and can be modified, added and changed. The data will need to be updated as time goes by. Parcels will be sold, merged, conserved, developed or remain the same. Land is static. dŚŝƐƌĞƉŽƌƚŝƐŐŽŝŶŐƚŽďĞĞůĞĐƚƌŽŶŝĐĂůůLJƌĞƉƌŽĚƵĐĞĚŽŶŝƚLJŽĨŝĚĚĞĨŽƌĚ͛ƐǁĞďƐŝƚĞ where changes can be made. We have had public input and we are looking for more feedback. Biddeford is on the move and adapting to the constant demand of undeveloped space on untapped resources. dŚŝƐŝƐŶŽƚĂƌĞƉŽƌƚŽŶ͞ƐƚŽƉĂůůŐƌŽǁƚŚĂŶĚŬĞĞƉĂůůŐƌĞĞŶ͘͟ It is an inventory, a resource item, and a foundation guide for future land conservation and planning efforts. It is also an outreach to landowners to offer them options on their choice of land use.

UNIVERSITY OF MAINE WORLD WAR II IN MEMORIAM DEDICATION In this book are the records of those sons of Maine who gave their lives in World War II. The stories of their lives are brief, for all of them were young. And yet, behind the dates and the names of places there shines the record of courage and sacrifice, of love, and of a devotion to duty that transcends all thought of safety or of gain or of selfish ambition. These are the names of those we love: these are the stories of those who once walked with us and sang our songs and shared our common hope. These are the faces of our loved ones and good comrades, of sons and husbands. There is no tribute equal to their sacrifice; there is no word of praise worthy of their deeds.

Eugene Shephard, P.E. Principal Project Manager Associate Engineer US District Court – District of Maine Alternatives Evaluation Report Penobscot River Phase III Engineering Study EXECUTIVE SUMMARY In January 2016, the United States District Court for the District of Maine (the Court) selected Amec Foster Wheeler Environment & Infrastructure, Inc. (Amec Foster Wheeler) to conduct the Penobscot River Phase III Engineering Study (Phase III Engineering Study), to identify and evaluate feasible, effective and cost-effective measures to remediate mercury in the Penobscot River Estuary (the Estuary). The geographic area to be addressed within the Phase III Engineering Study is described by the Court as “the region from the site of the former Veazie Dam south to Upper Penobscot Bay, including Mendall Marsh and the Orland River." Beginning in 1967, a chlor-alkali facility located in Orrington, Maine released mercury into the Estuary. Releases of mercury at overall declining concentrations continued throughout facility operation and ceased with facility closure in 2000. In 2002, the Court ordered an independent scientific study, the Penobscot River Mercury Study, to assess the spatial distribution and impact of mercury discharge in the Penobscot River.
