2. Request for Determination of Applicability (RDA), Mike Ahern, Town of Mansfield 1625/1675 West St
(Map 2 Parcel 7) and 311 Plain St (Map 1 Parcel 26), Mansfield, MA — Construction of a PFAS building at
Albertini Well property along with well site improvements within in the 100-foot buffer zones of Bordering
Vegetated Wetlands
Mr. Ahern stated that this was one of the final four(4) projects of upgrading our water treatment plants
and well infrastructure. The Albertini treatment plant is located at 1625/1675 West St. and its fed by five
(5) wells located onsite and at 311 Plain St. He explained that this project consisted of constructing a
new 3,500 SF PFAS building, adding a replacement well #4, electrical improvements, building
improvements, a green sand changeout, well and pump upgrades and chemical system improvements.
He noted that the project was outside the 100-foot buffer zone except for the replacement well. He
then stated the work located at 311 Plain St. entailed the following: demo of small building, installation
of new well pumps and motors, installation of underground utilities along the existing gravel roadway to
the main existing building area and off the right side of the existing gravel road to well 10/main building
area, installation of electrical switchgear and generator, utilities work to bring up the Towns SCADA fiber
optic network (Town well facilities will have a fiber backbone), erosion control and backfilling of utility
trenches daily.
Ms. Gonyer stated that the project was straight forward and Mr. Ahern did a great job explaining the
work. She then described the wetland delineations and spoke about the access roadway into each of the
sites. She stated that the project had minimal impact and she does not foresee any issues. Mr. Gallagher
asked when the work would be happening and Mr. Ahern said the Plain St. project would be happening
over the summer and that the Albertini project could go into the winter since a new building involved.
Motion: To issue a negative determination for Reason #3, work will not impact resource areas, to Mike
Ahern, Town of Mansfield, 1625/1675 West St (Map 2 Parcel 7) and 311 Plain St (Map 1 Parcel 26), Mansfield,
MA for the Construction of a PFAS building at Albertini Well property along with well site improvements

3. Request for Determination of Applicability (RDA), Andrea McDougall, 76 Pine Needle Lane, Mansfield,
MA (Map 31 Parcel 114) - Mansfield Housing Authority for the replacement of the existing failing septic
system located in the 100-foot buffer zone of a Bordering Vegetated Wetland (BVW).
Ms. Gonyer stated that this project is the replacement of a failed septic system located in the 100-foot
buffer zone of a BVW . The new leaching fields would be located on the side of the existing dwelling and
the old septic system and leaching fields would be abandoned. Mr. Carter, from GCG Associates was
there to represent the Mansfield Housing Authority, and he reviewed the proposed work with the
Commission explaining that the current system failed and the leaching field was very slow. The new
leaching field would be located on the side of the house in a lawn area with erosion control around the
back and a few trees would need to be removed to avoid having tree roots grow into the septic system.
The project was Board of Health approved and they will move forward if approved by the Conservation
Commission.
Ms. Gonyer mentioned there was a lot of disturbance from the test pits in the lawn. She stated that the
lawn is flat and then slopes down towards the wetland. She then asked that the erosion control be
installed to stabilize that area. She also noted that there was trash that was wind blown into that area
and asked that it be cleaned up. Mr. Roth asked if the pump chamber could be rotated outside of the
200-foot Riverfront Area Mr. Carter agreed to rotate the tank and also offered to install a generator
onsite in case the electricity went out.
Motion: To issue a negative determination for Reason #3 -work will not adversely impact resource area -

4. Notice of Intent (NOI), SE 211-1018 Joel Brandwine, Mansfield Municipal Airport Commission, 265 Fruit
Street, Mansfield, MA; Mansfield Municipal Airport for the reconstruction of the Airport's runway, taxi
way and stub taxiways, include regrading of areas in order to comply with Federal Aviation
Administration grading criteria along the stormwater management improvements within 100 feet of a
Bordering Vegetated Wetland and 200-foot Riverfront Area of Wading River.
Ms. Gonyer stated she walked the site with Mr. Rogers from GZA. Mr. Rogers introduced Mr. Duarte, the
Vice Chair of the Mansfield Airport as the Chair, Mr. Brandwind could not attend. He stated that they
have received funding from the FAA for the reconstruction of the airports runway to make it safer, to
create a better sheet flow and for better water management. The project also entails removal of a
paved area at the end of the end runway and that area would be converted into grass. There would be
minimal work in the Riverfront Area that would entail grading around the runway. Mr. Rogers noted that
this project has already been approved by the Town of Norton. Ms. Gonyer stated that she will ask
Norton for any of their special conditions after the issuing of the orders so we can compare with the
Town of Mansfield to make sure the special conditions do not contend with each other. She then stated
she did not see any issues with this project that would impact the resource areas. She then let Gale and
ZBA know that there was an issued/partial Certificate of Compliance (CDC) for the 2015 Airport
Vegetation Management Plan. There is still outstanding work invasive species management activities
that need to occur in order to complete the final COC. Ms. Gonyer will work with GZA and the Airport to
close out the 2015 Order of Conditions.

Conservation Commission Meeting Minutes 4.28.2025 Page 3 of 11
intersection within the 100-foot buffer zone of a Bordering Vegetated Wetland. Work will also include
culvert extension and replacement within an Intermittent Stream
The consultant for MassDOT, Mr. Roy the project manager from BETA Group, Inc., walked through the
plans of the Chauncy St/Copeland Drive project which included roadway and pedestrian improvements.
Ms. Tripp, the environmental scientist from BETA stated that work would be conducted within the 100-
foot buffer zone and that the work near Chauncy Street will include culvert replacements/extension
near an Intermittent Stream to help with water control. She then discussed that they would be cleaning
out the existing culvert as part of the project and adding seed mix to the stabilize the slopes in the
surrounding areas. Ms. Gonyer spoke about the new drainage coming in the system to the
Commissioners. She asked Ms. Tripp and their team what the goal/benefit was for this design, was it
going to correct the traffic concerns onto Rt. 140? Mr. Thompson from MassDot explained that currently
there is outdated undersized signal equipment on posts that needs to be replaced, there is currently no
bike path so this project will include the construction of a bike lane, along with updating all the
pedestrian curb ramps. Ms. Gonyer requested that as they move through phase 1 of the project and, if
any additional work is needed within jurisdiction, hey will need readdress it with the Commission. Mr.
Healey asked for the current and future Stormwater discharge rate. Mr. Thompson stated that the net
increase of impervious surface is about 16,000 SF and then asked Mr. Healey what were his concerns. .
Mr. Healey explained that in this part of Town within the past few years, residents are reporting
flooding in this area where they never experienced flooding before so when there is a projects like this is
in front of the Commission, it is incumbent on us to have an understanding of any potential changes to
the local hydrology especially if it increases in the stormwater discharge rate. He then asked if they
replaced the existing 18" lines and the 30" down the line, would this design be able to handle the
additional stormwater flow and not result in flooding. Mr. Roy stated that it would not add too much to
the 30 pipe. Ms. Tripp stated their Stormwater expert, was not present and noted that there would be
an increase in flow, however; considering the close proximity to the resource areas, that there would
not be a change in the Town stream conditions associated with the work that they are doing. Mr. Healey
asked with the project proposed project, is this the most efficient way to help with the stormwater flow.
Mr. Healey also inquired about which methodology they used to design the Stormwater Management
System as there are different ways that you could go about designing it. Mr. Roy stated they looked at
different alternatives for the roadway design and the shared use path was the best choice as it met all
the safety requirements for pedestrians and bicyclists and had the least amount of impact. Ms. Gonyer
added that they had received several complaints regarding flooding in this area and even though this
area is not in conservation jurisdiction, since we are making improvements hat which affect our
resource areas, we want to make sure it's the most beneficial to the Town. Mr. Gallagher asked if the
use of different material such as permeable pavers, would yield a better outcome . Mr. Thompson from
MassDOT stated it was a consideration however they do not prefer it unless it's absolutely necessary
since the materials and design were chosen for safety reasons. Mr. Roy stated they would like to start in
the Fall. Ms. Tripp and Ms. Gonyer discussed invasive species management during construction and Ms.
Gonyer stated that she would add that along with dewatering protocol into the conditions.
Motion: To issue an Order of Conditions to Erica Larner, Mass DOT Highway Division, for roadway and
pedestrian improvements to Chauncy St. (Rt. 106) from the intersection of Copeland Dr. to the Rt. 14C

the construction of a new dwelling, subsurface disposal system, driveway and associated grading of a
single-family home within 100 feet of a Bordering Vegetated Wetland (BVW). 1:05
Ms. Gonyer stated that she was on site with Mr. Oberlander and they agreed on the wetland lines. She
said it was a tight lot and there would be some regrading as well as a new septic (since sewer is not
offered there). Mr. Oberiander stated that this site is just south of the Airport/on the other side of Rt.
495. He described that the house location is25 feet from Azalea Road and described the areas of
regrading. He tried to keep the septic system as far as they could from the BVW and included a roof
drain system to capture the roof runoff from the house. The developed lawn area would be located
within the Limit of Work as shown on the site plan . He discussed the potential future construction of an
(Accessory Dwelling Unit) ADU which would require a separate filing with the Commission. Ms. Gonyer
also suggested a split rail fence to be installed along the 25-foot NDZ to the limit the area of the lawn.

within the 100-foot buffer zone of a Bordering Vegetated Wetland. MC 3.25.53-3.13.28
Mr. Buckley from the Bay Colony Group, Inc., explained that the 8 Julia Lane lot was developed roughly
10 years ago from the Willowdale sub division. He stated that the ADU would be disturbing about 39
square feet within the buffer zone, and about 65 feet from the BVW. There would be minimal woodland
disturbance, only two pine trees would be removed. Ms. Gonyer suggested some plantings of four (4)
hardwood saplings, such as red maple and oak to replace the trees being removed. The board discussed
the ADU size and how Mansfield had recently passed the law to be able to develop ADUs on single
family lots.

B. Notice of Intent (NOI), SE 211-1022 Benjamin Cavallo, 885 Maple St, Mansfield, MA (Map 40 Parcel
172), for the construction of a single-family dwelling with associated grading and utilities within the 100-
foot buffer zone of a Bordering Vegetated Wetland.
Mr. Gray from The Bay Colony Group walked the Commission through the proposed single-family
dwelling plans for 885 Maple St. which was currently surrounded by wetlands. Ms. Gonyer was
concerned about the buildout and the amount of buffer zone to be disturbed. She asked if the top of the
driveway could be reduced and Mr. Gray agreed. She then spoke about the Knotweed onsite and
mentioned that a Knotweed Management Plan would be a part of the special conditions to help stop the
spread of it.. Mr. Gallagher suggested to flip the house to reduce the amount of impervious driveway.
Mr. Gray explained that it was situated that way to get as much sunlight into the house as possible but
would speak to his clients. Mr. Gallagher also suggested reducing the size of the house and the patio as
it is too big for the lot. Mr. MacDonald asked if they had heard from NEHSP and they had not. Ms.
Gonyer explained once they do, they may or may not need to accommodate NHESP's comments
depending on what the letter stated. Overall, she agreed with Mr. Gallagher that the plans should be
reduced to fit better to this site due to the surrounding wetlands. She said they could continue this
hearing to the next meeting so Mr. Gray could work with his clients to reduce the plans.
Motion: To continue 885 Maple St, Mansfield, MA (Map 40 Parcel 172), to the next scheduled meeting.
Passes: 6:0 (MacDonald/Gallagher)
9. Notice of Intent (NOI), SE 211-1024 Michael & Jessica Woodward, 0 Erick Road, Mansfield MA (Map 41
Parcel 100) for the construction of a single-family dwelling and associated utilities within the 100-foot
buffer zone of a Bordering Vegetated Wetland (BVW).
Mr. Cygawnoski, RIM Engineering explained that Erick Road mostly consisted of condos and apartments
and this was the only single-family lot located close to Stearns Ave. He explained the existing conditions
regarding this single-family lot and the surrounding woodland. The Applicant proposed to subdivide the
lot and build another single-family dwelling s within 100-foot buffer zone of a BVW. He stated that the
new house would be on Town Sewer and that a sewer line would be bought in. He stated that the house
is a typical single-family house, 2-car garage and a patio in the back. Some trees would need to be
removed to fit the new driveway and utilities. Mr. Gallagher asked if Mr. Cygawnoski thought about
rotating the house about 90 degrees where the cars would enter a side entry garage, this would help to
protect the resource areas. He then stated with these new lots they may have to be creative to protect
the resource areas. Ms. Gonyer suggested to move the house back a little further to get away from the
resource area located to the left of the house. She suggested that they meet to review the trees onsite
to help with additional suggestions.
Resident Mr. Greg Martin, neighbors with Patrick Murphy, the owner of the abutting land next to 0 Erick
Road wanted to make sure that they would be protected from the water flowing from a new
construction like this. He mentioned that he spoke to Ms. Gonyer and he just wanted there to be a
solution to cover this. They did speak about drywells to help with this. He also wanted to know how it
will be managed for the 50- & 100-year storms. Mr. Hutton stated he would be happy to collaborate
with the owners of the new property and Mr. Cygawnoski asked for his contact information.
Mr. Brian Duarte, 95 Stearns Ave, an abutter wanted to reiterate his concerns for the water table,
removing trees, his privacy after tree removal and for the wildlife.

10. Notice of Intent (NOI), SE 211-1020 Stanley Feck, 0 Noonan St, Mansfield MA, (Map 19 Parcels 126-138),
for the construction of duplex residential building, grading and utilities within the 100-foot buffer zone
of a Bordering Vegetated Wetland (BVW
Mr. Craig Cygawnoski stated that Noonan and Snyder Streets were currently just paper roads and not
developed. He explained that there's 138 feet of frontage on Noonan Street and 83 Feet on Snyder
Street and that it backed up to wetlands that lead to the Robinson Brook. He noted that they were not
within the 200 -foot Riverfront Area of the brook. However, they were within the 100-foot buffer zone
of a BVW in the Northwest corner of the property. He proposed a duplex with a gravel driveway coming
from Webster St. The abutters driveway would not be disturbed. The sewer line is proposed within the
layout of Noonan Street and the water line is proposed along Synder Street since the water line could
not cross under the sewer.
Ms. Gonyer shared that the forested area where the duplex is proposed is relatively flat, she did not see
much concern regarding impacts to the resource areas per the plans. Mr. Gallagher mentioned that it
was lot on a small piece of property and asked if was it possible to move the water line. Mr. Cygawnoski
stated that their plan follows the new State regulations and the Town Engineer did not want the water
line moved. Ms. Gonyer added to Mr. Gallagher's suggestion to move the water line as she did not want
to disrupt wooded area near the resource areas. She will to speak with the Town Engineer to see if the
lines can be constructed within the layout of Noonan Street. Mr. Gallagher added that the proposed
water line will cause a lot of disturbance in that area and Ms. Gonyer spoke about adding plantings to
help with the situation and will see if the plan could be revised after she speaks with the Town Engineer.
Resident Mr. Dave Losiewicz, 31 Perkins Ave firmly opposed this project. His concerns were as follows:
(1) the construction of the public access road would cause the removal of hundreds of trees which are
within 100 feet of the wetlands,(2) it would be detrimental to the eco system, (3) and it would have a
negative impact on his property. He believes that new construction will increase the threat of flooding
to his property. He's never had flooding and has been there for 32 years and he attributes that to how
the surrounding properties are all set up.
Resident Mr. Ryan Blake, 21 Wester Street, agreed with Mr. Losiewicz concerns. When he moved to
Mansfield, he moved into this single-family neighborhood and now more and more duplex housing is
popping up and he's concerned with the diminishing greenery which originally attracted him to this
neighborhood. He would like to see the Conservation and surrounding land stay as is. Ms. Gonyer
reminded the board that they did not have the power to stop potential development on private
properties but they do have wetland jurisdiction to make sure none of the resource areas are harmed or
to cause any new Stormwater issues.
Resident/abutter Ms. Caryn Campbell, expressed her concern and opposition for the project due to
potential flooding, wildlife and vegetation endangerment. Ms. Gonyer reiterated that she is willing to sit
with the Town Engineer to discuss potential project changes to the utilities. The Commission agreed to
continue the meeting.
Motion: To continue this hearing to the next meeting.
Passes: 6:0 (Gallagher/Roth)
11. Request to Amend Order of Conditions (RAOOC), SE 211-1012 Igor & Faina Schwartz, 43 Lakeview
Ave, Mansfield MA (Map 4 Parcel 52). Applicant proposes to amend existing DOC to include the
replacement of the existing seawall along the inland bank of Greenwood Lake including remove of
several trees along the existing seawall. Mitigation plantings are proposed.
Mr. Craig Cygawnoski stated that they came before the Commission about a year ago for a house
addition and new septic system. This time ,they wanted to replace the existing retaining wall design with
a new red rock design and also add patios and decks. He also spoke with Ms. Gonyer regarding the trees
that they would like to have removed after construction . Mr. Cygawnoski then spoke about the
Conservation Commission Meeting Minutes 4.28.2025 Page 7 of 11
plantings that Ms. Gonyer suggested to have along the right side of the property. Mr. Healey talked
about the front wall as it is adding stability to the property however he was concerned about the open
grass area and potential runoff and suggested to continue the wall to the end of the property line to
have the lakeside protected. Mr. Cygawnoski informed Mr. Healey and the Commission that they now
have that open area to have direct access to the lake from their property. Mr. Healey expressed his
concern and Ms. Gonyer explained that the concern is not only the opening but the existing grading of
the property. She stated that if it was left open, the water will sheet flow from the street right down to
the beach. The Commission, Ms. Gonyer, Mr. Cygawnoski and the homeowners Mr. and Mrs. Schwartz
troubleshooted the plans of the property and how best to move forward including the plantings of the
property as to best protect the natural resources and to restore the habitat. Ms. Gonyer stated that she
would work with Mr. Cygawnoski and the homeowners regarding the plantings.
Resident Ms. Denise O'Connor, 47 Lakeview Ave, said the current wall goes to her property line and the
problem is the drainage. The street used to flood all the time for the previous two property owners. She
said there's an easement to the right of her property along with a drainage pipe so if this area floods,
the water will run right into the lake. Ms. O'Connor stated that she had not seen the plans yet and she's
most affected by it. She mentioned that quite a bit of trees had already been taken down. Ms. Gonyer
and Mr. Cygawnoski then reviewed the current plans with the resident so she understood them. Ms.
Denise O'Connor asked what the wall would be made of and they said it would be a concrete wall.
Motion: To issue an Amended Order of Conditions Igor & Faina Schwartz, 43 Lakeview Ave, Mansfield
MA (Map 4 Parcel 52) under SE 211-1012 to amend existing DOC to include the replacement of the
existing seawall along the inland bank of Greenwood Lake with the following special conditions (All

12. Notice of Intent (NOI), SE 211-1023 Ron & Susan Quintiliani, 41 Lakeview Ave, Mansfield MA (Map 4
Parcel 53) for the residential use of an Aquathruster, an underwater oscillator, within the waters for
Bungay/Greenwood Lake.
Ms. Gonyer stated this Aquathruster complaint had come in front of the Commissioners a few times and
there had been a meeting onsite with DEP. The DEP determined that it was in Mansfield's wetland
jurisdiction through the appeal process. The Quintiliani's filed this NOI to use the Aquathruster which is
an underwater fan to help introduce dissolved oxygen in the water and keep the area from becoming
stagnant. She then added that she had done some research with other towns and as long as the
Aquathruster was installed per the manufacturer's recommendation, it would not interfere with any
wildlife.
Conservation Commission Meeting Minutes 4.28.2025 Page 8 of 11
Mrs. Quintiliani stated that they use their Aquathruster at a 45-degree angle which is one notch up than
the manufacturer's recommendation so they do not disturb the land underneath. Mr. Quintiliani stated
they have it set up this way so it purposely does not disturb the bottom underneath. Ms. Gonyer asked
if it oscillated and he said yes but it's been broken. They intend to fix it because it flows towards the
retaining wall and then it bounces back towards the water. They installed this fan in the middle of June
which is at the end of fish spawning and he didn't see any fish or spawning beds front of his house. He
then added that you want to use it so it can disperse the algae so it does not build up. This lake had an
Aquatic Vegetation Management Plan and they have Wetlands & Waterways, a lake management
company, do annual treatments to help with this but the lake does still have eutrophication issues and
she would be attending their association meeting to discuss the aquatic DEP best management practices
guide. The DEP letter they received recommended that we review the aquatic guide for best practices
to see what applies to this project and site. Ms. Gonyer stated if the device is being used per the
manufacturer's recommendation, she does not believe it will cause a negative impact.
Mr. Devellis said he represented the abutter Mr. Boyden from the last RDA hearing and it was decided
that this was not in Conservation jurisdiction. He then mentioned that one of the commissioners asked if
he was a biologist/botanist and he stated he was a civil engineer. it was requested to have Mr. Boyden
hire a wild life /fish specialist. Mr. Boyden appealed the Commission determination of non -jurisdiction.
DEP repealed the Commission Determination stating that it is subject to land under the water it could
potentially affect the land under the water. Mr. Devellis looked at the NOI that was filed and was
expecting to see information proving that it would not impact the wildlife. He mentioned that it's the
same machine that will run the same way. He mentioned that the Conservation regulations says to come
up with a program or hire a specialist to determine how to use the Aquathruster. He asked if there was
going to be a program or will it be reviewed by a specialist. Mr. Boyden is concerned about the fish and
at the end of the day he wanted the spawning beds and critters to survive. The previous videos showed
the water being turned towards his wall. There's no program of use and the DEP said it disturbs the
bottom. There needs to be another way as this is not working.
Ms. Gonyer explained that there was no proof that anything was compromising the spawning beds or
killing fish. She then explained that this device does put dissolved oxygen into the lake and they are used
all over the lake. She asked if the device was to oscillate instead of stay in one place would that help?
Mr. Devellis said we need a professional to tell us that it's not effecting the spawning. The Bungay Lake
Association letter was read by Chair, Mr. Healey and it was in support of Aquathrusters which would
help the oxygen levels and the long-term health of the lake. That is consistent with his knowledge as
well as speaking with the fish hatchery. The hatchery stopped stocking the lake with fish years ago
because the lake is too warm and there's not enough oxygen. He then explained with his
educational/work background that oxygen is a key thing. Mr. Healey stated that if the Aquathruster is
properly installed it can only help the lake. Mr. Devellis said this is not good for his client. He would like
to have a biologist say that the area is ok. Ms. Gonyer said she understood that Mr. Devellis would like a
plan, she said if they had a plan and to avoid using it early Spring and Fall to avoid spawning would it
help? Mr. Devellis said we need a biologist to review and determine this. Ms. Gonyer asked if they
pointed the thruster towards their own house would it help make a determination. Mr. Boyden spoke
about the past 6-7 years and asked Ms. Gonyer if she ever lived on the water. He then explained that all
the garbage is in his area due to the Aquathruster. She then asked if they put the thruster near their
house instead of his house would he be happy? He then said that it's still an issue, it's too loud and it
would still move debris towards his house. Resident Mr. Ed Verocchi, 47 Lakeview Ave, said the
Aquathruster was not a fan but a hydraulic jet. He said it would not help if they changed the position as
he receives pine needles from his neighbors' yard at 151 Lakeview and it was pointed towards his house.
Mr. O'Hara stated that he studied this extensively and that he's never read or learned that these have a
negative impact on the water. Mr. Gallagher stated the lake association already hired a biologist and the
thruster was approved to be safe for the water. Ms. Gonyer read the DEP letter that stated it was in the
Conservation Commissions jurisdiction and that it only spoke to surface water and not the land under
the water.
