Subject:RE: Potential Isolated Land Subject to Flooding at 38 Willow Street
Hi Hannah
I have taken a quick look at the mapping on this area and it looks like there is a channel that runs along the north side of
Willow street under Route 6A and to the wetland area at Hallets Millpond. The property at 38 Willow street appears to
have vegetated wetland that has a connecting culvert under willow street and in theory flows to the channel on the
other side of the road. At first glance I would not have called this ILSF as it has an outlet. Does it meet the criteria of a
vegetated wetland under the bylaw? The best way to proceed would be to submit an RDA or ANRAD and submit the
material you have.
Thanks
Kelly

Good Afternoon Kelly,
I am reaching out to you to discuss a potential isolated land subject to flooding located on an undeveloped property at
38 Willow Street. A delineation was conducted in spring of 2019 by Matthew Creighton, and subsequent site visits have
also been conducted to determine if the pooled area near the northwestern corner of the property (which does not
appear on Mass GIS data layers) is associated with any other resource areas (no other resource areas were located on
the property of the neighboring properties to the north or south). We became concerned that this area may have
restricted drainage due to the blocking of a Mass DOT culvert which runs beneath Willow Street and continues along
what appears to be a manmade channel towards Main Street, where the channel continue northwest.
At the suggestion of Greg DeCesare of DEP, we conducted soil/vegetation plots along the channel on the northwestern
side of Willow Street towards Main Street (6A). Though there was significant redox within the first 60 feet of the
channel and a small vegetated area roughly 60-80 feet from the culvert, there were no areas between Willow Street and
Main Street which would qualify as a BVW or other resource areas based on our data collection. The area is comprised
of 80% invasive species such as Black Locust and Norway Maple, along with Morrow’s Honeysuckle, Multiflora Rose, and
1
English Ivey, even in or immediately adjacent to the channel. Investigations were also conducted north of the Main
Street culvert, which revealed much of the same.
Matt and I would like your opinion on the matter before we move forward with any permitting for 38 Willow Street. We
would be happy to attend a Site walk with you or submit photos/notes for your review.
Thank you for your time,
Hannah
