Road) at these three segments and three intersections during the latest three-year
period (i.e., 2006–2008).
Of the locations identified in Tables 2.2-4 and 2.2-5, two are currently under review
by the MaineDOT, as follows:
Cleaveland Street/Maine Street/Noble Street (Node 15874): This general area is
currently being reviewed by the MaineDOT. A new design is expected to change
the traffic patterns in a manner that addresses the issues related to the crash rate.
Bath Road East/Maine Street/Upper Park Row (Node 15873): Similar to Node
15874, this general area is currently being reviewed by the MaineDOT. A new
design is expected to change the traffic patterns that address issues related to the
crash rate.
In addition, there is an ongoing town-initiated corridor redesign for Bath Road from
approximately Cooks Corner to Old Bath Road/Lowe’s driveway. This redesign also
includes a review and potential retiming of the traffic signals at Tibbetts Drive (i.e.,
Wal-Mart) and at Old Bath Road/Lowe’s driveway. The redesign includes the
following HCLs:
Node 10343: Bath Road at Tibbetts Drive (i.e., Wal-Mart)
Segment 10343–13637: Bath Road from Tibbetts Drive to Thomas Point Road
2.3 Environmental Resources
This section describes the environmental resources in the Study Area. The existingconditions
inventory was compiled using various sources, as discussed herein.
Environmental resources inventoried include wetlands; surface water; groundwater;
floodplains; farmlands; rare, threatened, and endangered species; wildlife habitat;
and potential soil and groundwater contaminated sites.
2.3.1 Wetlands
The National Wetlands Inventory (NWI) mapping, National Resources Conservation
Service (NRCS) hydric-soils mapping, and aerial-photography–interpreted wetlands
provided by the Towns of Brunswick and Topsham were reviewed to determine the
potential location of wetlands in each transportation-strategy Study Area.
Environmental scientists verified potential wetlands by completing a windshieldlevel
field-reconnaissance effort on September 2 and 3, 2009. Due to minor changes in
the Study Area footprint, additional fieldwork was completed on May 21 and 22,
