Anderson Memorial Bridge Rehabilitation Project Public Information Meeting I July 22, 2010 Existing Paths – Cambridge Our team is coordinating with the Halvorson Design Partnership and the Charles River Basin Bicycle and Pedestrian Study Existing Conditions Report. Path connections to Anderson Bridge will be improved. Bridge Rehabilitation may affect the 3’ 3’ wide path at base of Anderson Memorial Bridge stairs. This path segment is not currently ADA compliant and may be replaced replaced as part of this project. Anderson Memorial Bridge Rehabilitation Project Public Information Meeting I July 22, 2010 Existing Paths – Cambridge and Boston Portions of these two paths near Memorial Drive may be affected during construction and may be replaced as part of this project. Narrow sidewalk on Soldiers Field Road leading to Newell Boat House is being studied. Anderson Memorial Bridge Rehabilitation Project Public Information Meeting I July 22, 2010 Trees: Horticultural Approach • Reconstruct bridge with minimal impact on trees. • Identify and assess condition of every tree in the project area. • Identify all trees that require protection during bridge rehabilitation in a tree inventory. • Identify all trees that affect the structural integrity of the historic bridge and compromise public safety. • Plant new large deciduous shade trees consistent with DCR’s Historic Parkway Preservation Treatment Guidelines, the Master Plan for the Charles River Basin, and the policies of the Cambridge and Boston Conservation Commissions to replace trees that need to be removed. Anderson Memorial Bridge Rehabilitation Project Public Information Meeting I July 22, 2010 What is there now? Tree Inventory – September 29, 2009 29 – Elm Species Every tree in project area has a number and a photograph. Anderson Memorial Bridge Rehabilitation Project Public Information Meeting I July 22, 2010 Tree Inventory •Trees in project area range in condition from poor to good. • Specimens include American Sentry Linden and American Elm. •Volunteer trees grow at bridge foundation, in armor stone and in riprap along river. •Invasive species such as Norway Maple and Common Buckthorn and Mulberry are present. •Dead limbs and compacted soil compromise health of some of the trees. Anderson Memorial Bridge Rehabilitation Project Public Information Meeting I July 22, 2010 Tree Inventory 36 – American Elm 36 – American Elm, Ulmus americana This elm is one, among many examples, of a special tree that requires protection. Anderson Memorial Bridge Rehabilitation Project Public Information Meeting I July 22, 2010 Tree Inventory 31: Elm Species 32 A: Hawthorn Some trees at the base of the bridge damage foundation and structure, interfere with repair and create hiding places. Anderson Memorial Bridge Rehabilitation Project Public Information Meeting I July 22, 2010 Where would trees require protection? Protect 3 American Sentry Lindens, Trees #61, 62 and 63 61,62, 63 – American Sentry Linden Anderson Memorial Bridge Rehabilitation Project Public Information Meeting I July 22, 2010 Why would you need to remove a tree? 31 – Elm damages foundation 32A – Hawthorn hides people on stairs 69 - 70 – Elms damage foundation Anderson Memorial Bridge Rehabilitation Project Public Information Meeting I July 22, 2010 Trees considered for Removal over 14” in diameter 5 trees over 14” 14” in diameter at breast height (DBH) may need to be removed, 3 in Cambridge, 2 in Boston. During the 2009 tree inventory, 7 trees in Boston were identified as 13” 13” DBH. They may grow to 14” 14” DBH by 2011. Roots at the wing wall foundations. The wall can not be rebuilt without removing some of the trees. 1- Norway Maple – volunteer at Bridge foundation in Boston Anderson Memorial Bridge Rehabilitation Project Public Information Meeting I July 22, 2010 Proposed Landscape Concepts • New trees will be planted to replace trees that need to be removed in order to rehabilitate bridge. The new trees will be deciduous shade trees. • Existing trees will be protected, pruned and fertilized. Proposed trees along path New paths to replace paths damaged during construction Existing Plane Trees along Memorial Drive Existing 3 Lindens near boathouse Proposed trees to replace volunteer trees Anderson Memorial Bridge Rehabilitation Project Public Information Meeting I July 22, 2010 Proposed Deciduous Shade Trees Swamp White Oak, Quercus bicolor Red Maple, Acer Rubrum “October Glory” Glory” American Sentry Linden, Tilia americana “American Sentry” Sentry” American Elm, Ulmus americana “Princeton” Princeton” Anderson Memorial Bridge Rehabilitation Project Public Information Meeting I July 22, 2010 Pin Oak, Quercus palustris Bloodgood Plane Trees, Platanus x acerifolia Opportunities for Pedestrian and Bicycle Improvements The Halvorson Design Partnership’s Charles River Basin Bicycle and Pedestrian Study • Improving connections between bridge sidewalk and bike lanes to paths in parkland on both the Boston and Cambridge sides of the Charles River. • Replacing segments of the existing paths affected by bridge rehabilitation. Anderson Memorial Bridge Rehabilitation Project Public Information Meeting I July 22, 2010 Improved Bicycle Accommodations Impacted portions of the Charles River Paths will be replaced with accessible paths New bike racks Cambridge Bike Racks Anderson Memorial Bridge Rehabilitation Project Public Information Meeting I July 22, 2010 Improved Bicycle Accommodations New bike racks Existing Bike Rack Cambridge Bike Racks Anderson Memorial Bridge Rehabilitation Project Public Information Meeting I July 22, 2010 Respect the façade of the historic bridge and facilitate future maintenance.
