Exeter town residentshave taken notice, but for all
others, construction on the Swasey Parkway is now complete and the roadway is
open to through-traffic. Last week the
roadway was reopened after repairs to the historic stone culvert. As part of a team effort with CMA Engineers, Ironwood
design group was called in to address the natural features of the site. Stabilization of the culvert’s banks with riprap
was a first step in preventing further soil erosion and water turbidity:
important as the culvert drains directly into the Squamscott River. The reconstruction
of the banks was done with openings and irregularity using the fallen stones to
provide habitat for native fish and anchorage for native species such as Sweet Flag (Acorus americanus) and New England Aster (Aster novae-angliae) to become established on the bank. Other native species such as Blue Flag iris, (Iris versicolor), Eastern Red Cedar (Juniperus virginiana) and Spicebush (Lindera benzoin) provide ornamental
enhancement for residents and double as food
and habitat for local fauna. Don’t forget to pay a visit next spring to
appreciate the lovely setting at the edges of Norris Brook-the site of a
previous Ironwood restoration effort. Signage there explains the significance
of wetland species in detaining and cleaning storm water.
