Frequently Asked Questions: Waterford Iron Bridge Replacement
What impact will there be on the Carleton Arboretum?
While the Arboretum Committee worked hard to minimize impact, some negative
impacts are inevitable. There are three identified categories of impact:
- short term ecological
- long term ecological, and
- aesthetic
In the short term we will see ecological impact to the floodplain forest in the area the new bridge will occupy and in the construction zone needed to build the bridge. Two groups of large cottonwood trees will be removed, and a number of smaller cottonwood, ash, and river birch will also be removed. We hope to provide the lumber from these trees to the Carleton Art Department for use in art and furniture projects.
In the long term we expect that there will be changes in the river and floodplain forest dynamics due to changes in water flow patterns and constraints to the river channel caused by the piers of the new bridge. We expect these to be minimized as much as possible by the changes we have requested in the bridge design and approach.
Lastly, there is no doubt that the new bridge will look quite different than the existing Iron Bridge. The new bridge will be substantially larger and will be a more imposing presence to those exploring the Arboretum on foot or by boat.
The Waterford Town Board has assured Carleton that it is committed to maintaining the rural character of this area. There are no plans to pave Canada Avenue.
