Dear Ms. Hughes:
Christiansen & Sergi, Inc. (C&S) conducted its weekly erosion and sedimentation
control inspection on March 7, 2014 to review the status of site conditions, erosion
control measures, and wetland resource areas at the subject property. Except
for plowed areas, snow still covers the site. The status report is intended to
comply with Condition 52 of the Order of Conditions issued by the Town of North
Andover Conservation Commission.
Work since the last inspection was limited to the house construction on Lots 6, 7,
8, and 31. No excavation work has occurred. The following observations were
noted:
1. The interior construction of the houses on Lots 6, 7, and 31 continues.
2. The framing of the house on Lot 8 continues.
There are no outstanding erosion control issues at this time.

Dear Ms. Hughes:
Christiansen & Sergi, Inc. (CBIS) conducted its post-rainfall erosion and
sedimentation control inspection on March 13, 2014 to review the status of site
conditions, erosion control measures, and wetland resource areas at the subject
property. The inspection took place after about 0.4 inches of rain and 2 inches
of snow fell on March 12th and 13th. Except for plowed areas, snow still covers the
site. The status report is intended to comply with Condition 52 of the Order of
Conditions issued by the Town of North Andover Conservation Commission.
Work since the last inspection was limited to the house construction on Lots 6, 7,
and 31 . The only excavation work that occurred was the shoring up of the
erosion control along and below the driveways. The following observations were
noted:
1. The interior construction of the houses on Lots 6, 7, and 31 continues.
2. A crushed stone berm was built along the upgradient side of the
sedimentation control barrier above the Lot 5 rain garden. There were
areas below the barrier where recent runoff had melted channels through
the older snow. I cleared the new snow from one of the channels and the
grass below was clean. There was no evidence of sediment transport or
deposit below the sedimentation control barrier or in the rain garden
forebay.
3. Caution tape was installed across the bottom of the Lot 31 driveway to
prevent vehicles from driving through an area that is becoming soft as the
frost thaws.
4. A crushed stone berm was installed along the right side of the Lot 7
driveway to prevent sediment transport into the downgradient grass swale
that leads to the rain garden on Lot 6 and 7. There was no evidence of
breaches or overtopping of the berm.
5. A crushed stone check dam was installed across the Lot 7 driveway at a
point about 2/3 of the way up the driveway.
6. A pile of crushed stone was placed at the bottom of the Lot 8 driveway.
This stockpile acts a filter for any runoff flowing down the driveway.
7. The crushed stone filter strips across the driveways for Lots 6, 7, and 31
were refreshed.
8. There was standing water in the Gravel Wetland, indicating that the runoff
from the upper portion of the roadway was being captured by the 4
upper catch basins.
9. There was standing water in the forebay of Infiltration Basin #2. The main
basin was covered with ice and snow except for a small area in front of
the emergency spillway. There was no evidence of overtopping at the
spillway, but the standing water/ice level was just below the spillway
elevation. The water level in the basin will continue to be monitored. If
standing water remains in the basin as the ice and snow melts the water
should be pumped down to reestablish storage capacity and to allow for
an evaluation as to why the basin isn't draining properly.
There are no outstanding erosion control issues at this time.

Dear Ms. Hughes:
Christiansen & Sergi, Inc. (CSS) conducted its post-rainfall erosion and
sedimentation control inspection on March 21, 2014 to review the status of site
conditions, erosion control measures, and wetland resource areas at the subject
property. The inspection took place after about 0.5 inches of rain fell on March
20th. There has also been substantial snow melt during the last week. The status
report is intended to comply with Condition 52 of the Order of Conditions issued
by the Town of North Andover Conservation Commission.
Work continued on several of the houses this week, and excavation work was
started up again. The following observations were noted:
1 . The interior construction of the houses on Lots 6, 7, and 31 continues.
2. Exterior framing of the house on Lot 8 continues.
3. The foundation for the house on Lot 4 was being poured at the time of the
inspection.
4. The driveways on Lots 31, 6, 7, and 8 were re-graded/re-shaped with
native sandy soils and crushed stone.
5. Additional grading of the front yard on Lot 8 occurred.
6. There was silty water in the forebay above the rain garden on Lot 5. It
appears that sediment from a small loam pile located to the west of the
forebay is washing into the forebay. It was evident that some of the
sediment flowed over the forebay berm into the first 10' or so of the rain
garden. The accumulated sediment should be removed from the rain
garden floor as soon as conditions allow. An erosion control barrier should
be placed along the downgradient end of the loam stockpile as soon as
possible to prevent further sediment transport into the rain garden, and
the stockpile should be removed as soon as conditions allow. I left a
message for Brian Dube of Dirt-Pro about this issue.
7. There was standing water in the Gravel Wetland, and the water in the
overflow manhole was about an inch below the outlet orifice.
8. There was standing water in the Infiltration basin below the gravel
wetland, and in a depression in the woods to the east of the infiltration
basin. It appears that most, if not all, of the water in the infiltration basin
came from the upgradient depression in the woods and not from the
gravel wetland. Water was overflowing from the depression into the
infiltration area at the time of the inspection. The water levels in the
infiltration basin and depression will be monitored.
9. There was standing water in the forebay of Infiltration Basin #2. The main
basin was covered with ice and snow except for a small area in front of
the emergency spillway. Though there was no evidence of overtopping
at the spillway, it appears that water may be draining through or under
the rip-rap of the spillway. The ground along the erosion control barrier
below the spillway was very soft and wet. There were two garden hoses in
the forebay, so it appears that an attempt is being made to siphon some
of the water from the basin. The water should be pumped down to stop
the overflow through the rip-rap and to provide retention for stormwater
until the infiltration can be restored.
Dirt-Pro should perform the noted maintenance and monitor/reinforce the
erosion control barriers on a daily basis.

Dear Ms. Hughes:
Christiansen & Sergi, Inc. (C&S) conducted its weekly erosion and sedimentation
control inspection on March 28, 2014 to review the status of site conditions,
erosion control measures, and wetland resource areas at the subject property.
The last significant rainfall event was 0.5 inches on March 20th. The status report
is intended to comply with Condition 52 of the Order of Conditions issued by the
Town of North Andover Conservation Commission.
Work continued on several of the house lots this week. The following
observations were noted:
1. The interior construction of the houses on Lots 6, 7, and 31 continues.
2. Exterior framing and sheathing of the house on Lot 8 continues.
3. A boulder retaining wall was started at the front right corner of the house
on Lot 31 to accommodate the grade change for the garage-under.
4. The foundation for the house on Lot 4 was backfilled and the yard area
surrounding the foundation was rough graded.
5. There was standing water in the forebay above the rain garden on Lot 5,
just below the overflow elevation. As noted in the previous inspection
report, erosion control barriers should be placed above the forebay and
between the forebay and the rain garden to prevent further sediment
transport into the rain garden. I left a message for Brian Dube of Dirt-Pro
this afternoon requesting that these barriers be installed before the heavy
rain tomorrow evening.
6. There was an area in the front of Lot 1 where sediment was accumulating
at the top of the slope above the forebay of the gravel wetland. An
erosion control barrier should be installed across the top of the slope to
prevent sediment from flowing into the forebay and gravel wetland. In
the message I left for Brian Dube I requested that these barriers be
installed before the heavy rain tomorrow evening.
7. The crushed stone filters in the driveways on Lots 6 & 31 are clogged and
need to be refreshed. This should be done before work trucks attempt to
use the driveways after the heavy weekend rain.

Dear Ms. Hughes:
Christiansen & Sergi, Inc. (C&S) conducted its post-rainfall erosion and
sedimentation control inspection on March 31, 2014 to review the status of site
conditions, erosion control measures, and wetland resource areas at the subject
property. Site contractor Brian Dube from Dirt-Pro was present for the inspection.
Brian was on site on both Saturday and Sunday to monitor and maintain/repair
the erosion control measures during the storm. Conservation Field Inspector
Heidi Gaffney was also present for part of the inspection. The inspection took
place after about 2.5 inches of rain fell between March 29th and March 31st.
The status report is intended to comply with Condition 52 of the Order of
Conditions issued by the Town of North Andover Conservation Commission.
The following observations were noted:
1. A washout of a stockpile of stone dust and gravel occurred on Lot 31.
Some of the washed out material overtopped the hay bale/silt fence
barrier into the woods above the isolated wetland behind the lot. The
sediment has stopped just about at the flagged edge of the wetland,
near Flag A-7.5. The sediment is primarily a course grained material, and
the water flowing over it was clear at the time of the inspection. Brian
said that his crew will be back at the site starting on Wednesday, and as
soon as it is dry enough will remove all of the sediment that is beyond the
erosion control barrier using hand shovels. They will also remove the built
up sediment from along the barrier and replace or shore up the barrier as
necessary. The upgradient stockpile will be removed and the disturbed
area will be finish graded, loamed, and covered with an erosion control
mat.
2. There was an area behind Lot 4 where sediment laden runoff flowed
either under or through the erosion control barrier. The sediment extends
about 15-20 feet beyond the barrier, and is about 60- 65 feet
upgradient from Flags C-3 and C-4. As soon as conditions are dry enough
Dirt-Pro will remove the sediment from beyond the barrier by hand and
shore up or replace the barrier.
3. Infiltration Basin 1 (on Lot 1) was holding water at its top of berm elevation.
There was evidence that the basin had overflowed during the storm (as
designed) into the downgradient wooded area. Water was flowing
through the orifice of the Gravel Wetland outlet control structure into the
infiltration basin, and the ponded water in the depression in the woods to
the east of the infiltration basin was overflowing into the infiltration basin.
The water levels will continue to be monitored.
4. The water level in Infiltration Basin 2 (on Lot 3) was higher than it was
during the inspection before the storm, but there was no sign of
overtopping through the spillway. Garden hoses are being used to siphon
some of the water out of the basin to restore the capacity.
5. There was standing water within the forebay and main basin of the rain
garden on Lot 5. The water was slightly cloudy. The rain garden may
need to be raked after it dries out if any sediment remains on top of the
mulch. Dirt-Pro intends to start the finish grading and stabilizing of the
upgradient disturbed areas later this week.
6. There was standing water within the forebay of the rain garden on Lots 6
and 7. There was no evidence of overflow into the main basin of the rain
garden.
7. There was an accumulation of topsoil below the downgradient end of the
box culvert under the Lots 5/6/31 driveway. There is no evidence of
sediment on the upgradient side of the box culvert, so it appears that the
topsoil came from backfilled channel within the box culvert. The topsoil is
trapped by the erosion control barrier. The accumulated topsoil should
be removed as soon as it dries out enough.
Dirt-Pro should perform the noted maintenance and monitor/reinforce the
erosion control barriers on a daily basis.
Regards,
Daniel J. O'Connell
Christiansen & Sergi, Inc.
8. The standing water noted in the previous report in the infiltration basin
below the gravel wetland has nearly all drained into the ground. The
ponded water in the depression in the woods to the east of the infiltration
basin still holds water, though it is no longer overflowing into the infiltration
basin.
9. The standing water noted in the previous report in Infiltration Basin #2 has
dropped several inches since the last inspection. There is one garden
hose siphoning water from the basin, but it appears that the inflow from
the roadway subdrains and melting snow is greater than the rate of the
siphon, so infiltration is occurring.
Dirt-Pro should perform the noted maintenance and monitor/reinforce the
erosion control barriers on a daily basis.

Dear Ms. Hughes:
Christiansen & Sergi, Inc. (CBIS) conducted its weekly erosion and sedimentation
control inspection on April 4, 2014 to review the status of site conditions, erosion
control measures, and wetland resource areas at the subject property. The last
significant rainfall event was 3.3 inches on March 29'" - 31st. The status report is
intended to comply with Condition 52 of the Order of Conditions issued by the
Town of North Andover Conservation Commission.
Work continued on several of the house lots this week. The following
observations were noted:
1 . The interior construction of the houses on Lots 6, 7, and 31 continues.
2. Exterior framing and sheathing of the house on Lot 8 continues.
3. The cleanup of the sand and sediment that washed through the erosion
control barrier into the buffer zone behind Lot 31 is underway. A silt sock
had been placed across the slope about 10 feet above the edge of
wetland, and all sediment has been cleaned up from below the silt sock.
The cleanup of the remaining sediment is ongoing, with sediment being
scraped up with hand shovels and deposited into a wheelbarrow for
removal.
4. The stockpile that created the sediment on Lot 31 has been removed,
and the yard area has been re-graded. A swale has been constructed at
the bottom of the slope, the swale has been loamed and seeded, and
erosion control mats have been installed over the Swale. A hay bale
check dam was installed at the top of the swale.
5. There was a shallow area of standing water in the forebay above the rain
garden on Lot 5. The bottom of the forebay was covered with mucky
leaves. The sediment and leaves should be removed when the forebay
dries completely to prevent re-suspension.
6. The main basin of the rain garden on Lot 5 has drained completely since
the storm, and the water level in the inspection port was approximately 18
inches below the floor of the rain garden.
7. Hay bale barriers had been added above the forebay of the rain garden
on Lot 5 and between the forebay and the rain garden. A silt sock was
also added upgradient of the forebay. The area above the erosion
control barrier above the rain garden forebay (below the Lot 31 driveway)
was re-graded, and accumulated sediment was removed.
8. A pile of crushed had been dumped at the beginning of the Lot 31
driveway and Dirt-Pro was intending to use the stone to refresh the stone
aprons this afternoon.
9. The forebay of the rain garden on Lots 6 and 7 has drained completely
since the storm. There is a slight coating of silt on the rip-rap in the
forebay, but not enough to be a concern, and too little to be cleaned.
10. An inspection was made of the area behind Lot 4 where sediment had
flowed either under or through the erosion control barrier. The sediment
extends about 15-20 feet beyond the barrier, but is about 60- 65 feet
upgradient from Flags C-3 and C-4. The reason for the sediment beyond
the barrier is that the silt fence is torn at the bottom and has several holes.
I spoke to Brian Dube from Dirt-Pro about this and he said that he would
replace the damaged section of silt fence. The slope above the barrier is
still too wet to get close enough to remove the built up sediment in front
of the barrier, but as soon as conditions are dry enough Dirt-Pro will
remove the sediment.
11. Infiltration Basin 1 (on Lot 1) was holding water about 4 inches below its
top of berm elevation. There was a steady flow of water into the basin
from the gravel wetland and from the upgradient depression in the
woods, which was still overflowing into the basin. It appears that the
infiltration occurring through the basin floor exceeds the inflow so the
basin should continue to drain. The water levels will continue to be
monitored.
12. The water level in Infiltration Basin 2 (on Lot 3) continues to drop. It is now
about 12 inches below the overflow spillway elevation. There was a
steady flow of water into the basin from the drainage system, most likely
from the roadway subdrains, and garden hoses were being used to
siphon some of the water out of the basin. The rate of water being
siphoned out appeared to be about the same as the rate coming in from
the drainage system.
13. Additional site grading was ongoing in the front yards of lots 7 and 8.
Dirt-Pro should perform the noted maintenance and monitor/reinforce the
erosion control barriers on a daily basis.

Dear Ms. Hughes:
Christiansen & Sergi, Inc. (C&S) conducted its weekly erosion and sedimentation
control inspection on April 11, 2014 to review the status of site conditions, erosion
control measures, and wetland resource areas at the subject property. The last
significant rainfall event was 0.47 inches on April 7th and 8th. The status report is
intended to comply with Condition 52 of the Order of Conditions issued by the
Town of North Andover Conservation Commission.
Work continued on several of the house lots this week. The following
observations were noted:
1. The interior construction of the houses on Lots 6, 7, 8, and 31 continues.
2. The cleanup of the sand and sediment that washed through the erosion
control barrier into the buffer zone behind Lot 31 has been completed.
3. The swale that was constructed at the bottom of the slope behind Lot 31
is in very good condition, with no apparent damage or erosion from the
rainfall earlier in the week.
4. The forebay above the rain garden on Lot 5 was holding clear water
about 10" deep. The hay bale barriers and silt sock above the forebay
and the hay bale barrier along the overflow into the rain garden appear
to be effectively filtering runoff. There was no standing water in the rain
garden. There was no water present in the inspection port (at a depth of
about 24" below the floor of the basin).
5. The crushed stone aprons at the beginnings of the driveways to Lots 6, 7,
8, and 31 have been refreshed since the last inspection and were in good
condition.
6. A new section of silt fence was placed downgradient of the damaged
section behind Lot 4. Bark mulch was placed along the upgradient side
of the new silt fence as an additional filter.
7. Infiltration Basin 1 (on Lot 1) was holding water about 6 to 8" deep (about
12" below the surrounding berm elevation). There was a steady flow of
water into the basin from the gravel wetland. The upgradient depression
in the woods is holding water about 3 to 4" below the overflow elevation
where it was previously draining into the basin. The water levels will
continue to be monitored.
8. The bottom of Infiltration Basin 2 (on Lot 3) is dry. (According to Brian
Dube from Dirt-Pro, the basin had about 8" of standing water after the
rain on Tuesday.) I dug a hole in the middle of the basin about 10" deep,
and the bottom of the hole was damp but not saturated. The forebay
was holding clear water about 10" deep. There was a low flow of water
into the forebay from the drainage system (water collected by the
subdrains). Two garden hoses were being used to siphon water from the
forebay.
9. Additional site grading had occurred in the front yard of Lot 4.
10. Additional site grading occurred along the Lot 7 driveway, and fresh hay
mulch was spread along the downgradient shoulder and swale.
11. Work was underway on the boulder retaining wall at the front corner of
the garage of the house on lot 8.
Dirt-Pro should continue to monitor the erosion control barriers on a daily basis
and reinforce or replace as needed.

Dear Ms. Hughes:
Christiansen & Sergi, Inc. (C&S) conducted its post-rainfall erosion and
sedimentation control inspection on April 17, 2014 to review the status of site
conditions, erosion control measures, and wetland resource areas at the subject
property. The last significant rainfall event was 0.76 inches on April 15th and
16th. The status report is intended to comply with Condition 52 of the Order of
Conditions issued by the Town of North Andover Conservation Commission.
Work continued on several of the house lots this week. The following
observations were noted:
1. The interior construction of the houses on Lots 6, 7, 8, and 31 continues.
2. The exterior framing of the house on Lot 4 has started.
3. The swale that was constructed at the bottom of the slope behind Lot 31
is in very good condition, with no apparent damage or erosion from the
rainfall.
4. The forebay above the rain garden on Lot 5 was holding clear water
about 10" deep. The hay bale barriers and silt sock above the forebay
and the hay bale barrier along the overflow into the rain garden appear
to be effectively filtering runoff. There was no standing water in the rain
garden, though the area immediately below the forebay was damp.
There was no water present in the inspection port (at a depth of about
24" below the floor of the basin).
5. Infiltration Basin 1 (on Lot 1) was holding water about 6" deep. There was
a low flow of water into the basin from the gravel wetland. The
upgradient depression in the woods is holding water just below the
overflow elevation. There were indications that it had overflowed into the
infiltration basin during the storm. The water levels will continue to be
monitored.
6. Standing water covered about 80% of the bottom of Infiltration Basin 2, to
an average depth of about 1". The forebay was holding clear water
about 12" deep. There was a low flow of water into the forebay from the
drainage system (water collected by the roadway subdrains). Two
garden hoses were present and had previously been used to siphon water
from the forebay, though neither was functioning at the time of the
inspection.
There are no outstanding erosion control issues at this time. Dirt-Pro should
continue to monitor the erosion control barriers on a daily basis and reinforce or
replace as needed.

sedimentation control inspection on April 24, 2014 to review the status of site
conditions, erosion control measures, and wetland resource areas at the subject
property. The inspection took place one day after about 0.7 inches fell on April
23rd. The status report is intended to comply with Condition 52 of the Order of
Conditions issued by the Town of North Andover Conservation Commission.
Work continued on several of the house lots this week. The following
observations were noted:
1. The interior construction of the houses on Lots 6, 7, 8, and 31 continues.
2. The exterior framing of the house on Lot 4 continues.
3. The front, left side, and back yards of Lot 31 were brought to subgrade to
prepare for final loaming and seeding. The retaining wall and stairs at the
right front corner of the house were completed.
4. The swale that was constructed at the bottom of the slope behind Lot 31
is in very good condition, with no apparent damage or erosion from the
rainfall.
5. The forebay above the rain garden on Lot 5 was holding water about 10"

6. There was no evidence of flow into or out of the forebay of the rain
garden on Lots 6 and 7.
7. Infiltration Basin 1 (on Lot 1) was holding water about 5" deep. There was
a steady flow of water into the basin from the gravel wetland. The
upgradient depression in the woods is holding water just below the

8. Standing water to a depth of about 2" covered almost the entire bottom
area of Infiltration Basin 2. (The basin was dry on the day before the
storm.) The forebay was holding clear water about 12" deep. There was
a low flow of water into the forebay from the drainage system (water
collected by the roadway subdrains).
There are no outstanding erosion control issues at this time. Dirt-Pro should

Dear Ms. Hughes:
Christiansen & Sergi, Inc. (C&S) conducted its post-rainfall erosion and
sedimentation control inspection on May 2, 2014 to review the status of site
conditions, erosion control measures, and wetland resource areas at the subject
property. The inspection took place one day after about 0.9 inches fell on April
30th and May 1 st. The status report is intended to comply with Condition 52 of
the Order of Conditions issued by the Town of North Andover Conservation
Commission.
Work continued on several of the house lots this week. The following
observations were noted:
1 . The interior construction of the houses on Lots 6, 7, 8, and 31 continues.
2. The exterior framing of the house on Lot 4 continues.
3. The foundation for the house on Lot 2 was installed and was being
backfilled at the time of the inspection.
4. The swale that was constructed at the bottom of the slope behind Lot 31
is in very good condition, with no apparent damage or erosion from the
rainfall. Grass is starting to grow in the swale.
5. The forebay above the rain garden on Lot 5 was holding water at the
overflow elevation into the rain garden. The first 15 feet or so of the rain
garden was wet. The hay bale barriers and silt sock above the forebay
and the hay bale barrier along the overflow into the rain garden appear
to be effectively filtering runoff.
6. There was no evidence of flow into or out of the forebay of the rain
garden on Lots 6 and 7.
7. Infiltration Basin 1 (on Lot 1) was holding water about 12" deep. There was
a steady flow of water into the basin from the gravel wetland. The
upgradient depression in the woods was overflowing into the infiltration
basin. The water levels will continue to be monitored.
8. Standing water to a depth of about 4" covered the bottom area of
Infiltration Basin 2. (There were water marks on the stakes in the basin that
indicated that the water level was about 1" higher during the storm.)
There was a low flow of water into the forebay from the drainage system
(water collected by the roadway subdrains).
9. Additional grading had occurred in the yard on Lot 8.
10. It was noted that the grass seed that was sown last fall is starting to grow
along the road shoulders.
There are no outstanding erosion control issues at this time. Dirt-Pro should
continue to monitor the erosion control barriers on a daily basis and reinforce or
replace as needed.

Dear Ms. Hughes:
Christiansen & Sergi, Inc. (C&S) conducted its weekly erosion and sedimentation
control inspection on May 8, 2014 to review the status of site conditions, erosion
control measures, and wetland resource areas at the subject property. The
inspection took place seven days after about 0.9 inches fell on April 30th and
May 1 st. The status report is intended to comply with Condition 52 of the Order
of Conditions issued by the Town of North Andover Conservation Commission.
Work continued on several of the house lots this week. The following
observations were noted:
1 . The interior construction of the houses on Lots 6, 7, 8, and 31 continues.
2. The exterior framing of the house on Lot 4 continues.
3. The foundation for the house on Lot 2 was backfilled and rough grading
has occurred around the house.
4. The swale that was constructed at the bottom of the slope behind Lot 31
is in very good condition, with grass continuing to grow.
5. The forebay above the rain garden on Lot 5 was holding water just below
the overflow elevation into the rain garden. The first 15 feet or so of the
rain garden was wet. The hay bale barriers and silt sock above the
forebay and the hay bale barrier along the overflow into the rain garden
appear to be effectively filtering runoff. The Lot 5 end of the swale
leading to the forebay was being shaped and loamed at the time of the
inspection.
6. Infiltration Basin 1 (on Lot 1) was holding water about 1" deep. There was
a steady flow of water into the basin from the gravel wetland. The water
in the upgradient depression in the woods was a few inches below the
overflow elevation into the infiltration basin. The water levels will continue
to be monitored.
7. The bottom area of Infiltration Basin 2 was dry. There was a low flow of
water into the forebay from the drainage system (water collected by the
roadway subdrains).
8. Pine trees were planted around the front, left side, and back of Infiltration
Basin #2 and around the right side of yard on Lot 4.
9. The front yard of Lot 31 has been finished graded and foamed.
10. The area for the septic system on Lot 7 was being excavated at the time
of the inspection.
11. The driveway for Lot 31 was being graded in anticipation of paving next
week. The shoulders were being shaped.
There are no outstanding erosion control issues at this time. Dirt-Pro should
continue to monitor the erosion control barriers on a daily basis and reinforce or

Dear Ms. Hughes:
Christiansen & Sergi, Inc. (C&S) conducted its post-rainfall erosion and
sedimentation control inspection on May 17, 2014 to review the status of site
conditions, erosion control measures, and wetland resource areas at the subject
property. The inspection took place after 0.9 inches of rain fell on May 16th and
17th. The status report is intended to comply with Condition 52 of the Order of
Conditions issued by the Town of North Andover Conservation Commission.
There were no apparent erosion control problems after the storm. The following
observations were noted:
1. The forebay above the rain garden on Lot 5 was holding water at the
overflow elevation and was slowly draining into the rain garden. The first
15 feet of the rain garden had standing clear water less than an inch
deep.
2. The bottom of Infiltration Basin 1 (on Lot 1) had standing clear water about
an inch deep immediately below the rip-rap at the inlet. There was a
steady flow of water into the basin from the gravel wetland. The water in
the upgradient depression in the woods was just below the overflow
elevation into the infiltration basin.
3. The bottom area of Infiltration Basin 2 was dry, though water was visible
around the edges of the stone where the elevation is slightly below the
basin floor elevation. The forebay was overflowing into the infiltration
basin ata low rate. There was a low flow of water into the forebay from
the drainage system (water collected by the roadway subdrains).
4. The forebay of the rain garden on Lots 6 and 7 had 2-3 inches of
standing water. There was no evidence of overflow into the rain garden.
5. There was some minor rill erosion on some of the newly loamed slopes, but
no significant build-up along any of the erosion control barriers.
There are no outstanding erosion control issues at this time. Dirt-Pro should
continue to monitor the erosion control barriers on a daily basis and reinforce or
replace as needed.
