EXECUTIVE SUMMARY
1.0 Introduction
The Sconset Beach Preservation Fund (SBPF) is permitted under SE48-2824 to install
geotextile tubes at the base of the bluff below 87-105 Baxter Road, vegetate the bluff, and
install a coastal drainage system (including a catch basin) at 91 Baxter Road (these activities
are referred to as “the “Project”). The Project was constructed in two phases. The first
phase was constructed in late December 2013 and January 2014 under an Emergency
Certification approval issued by the Nantucket Conservation Commission. The first phase
consisted of the installation of three stacked tiers of 45-foot circumference geotextile tubes
at the base of the eroding Sconset Bluff. The geotextile tube installation was approximately
852 feet long and extends along the toe of the bank from 87-105 Baxter Road. The second
phase was constructed in October 2015 through February 2016 and includes the
installation of a fourth tier of geotextile tubes on lots 91-99, intermediate returns, end
returns, and a surface runoff drainage system. With the returns included, the total project
length is now 947 feet
As part of the Order of Conditions for the geotextile tube project, an annual review of the
Project is required to review the Project’s monitoring and mitigation programs. This Annual
Report has been prepared to review the existing monitoring data (Section 4.0) and provide
recommended changes to monitoring and mitigation programs for the future (Section 5.0).
2.0 Key Findings
Significant monitoring has occurred during the over 4 year period since the initial
construction of the geotextile tubes in late 2013: 13 shoreline surveys (including six
bathymetric surveys), 4 underwater video surveys, five wetland wells monitoring events,
beach invertebrate monitoring at four locations, two drainage system reports, and aerial
surveys of the bluff. SBPF has also regularly submitted work reports detailing all template
re-grading activities.
After over four years of monitoring, there is no indication of adverse effects to adjacent
beaches, the nearshore hard bottom environment, the wetlands at the top of the bluff, or
beach invertebrates. Following are the key findings from the monitoring data.
♦ The shoreline monitoring data shows that the measured shoreline positions and the
rate of shoreline change are similar to historic patterns. There is no indication of
accelerated erosion in excess of historical observations in front of or adjacent to the
geotubes.
♦ The bluff survey indicates that the mitigation sand template has contributed nearly
three times more sand (15.5 cubic yards/linear foot/year [cy/lf/yr]) than the
unprotected bluff (5.8 cy/lf/yr) over the last four years.
21597/Sconset E-2 Annual Review
Epsilon Associates, Inc.
♦ Underwater video surveys show that a productive habitat area is located just
offshore from the geotextile tubes, with no indication that such cobble habitat is
being impacted by the sand mitigation.
♦ The significant mitigation required at Sconset is uniquely conservative. The
mitigation volume of 22 cy/lf/yr is 1.5-1.8 times the average bank contribution.1
Ten comparable bank and dune protection projects2 on the Cape & Islands provided
mitigation equivalent to the average bank contribution volume; in most cases, the
mitigation volume was estimated by multiplying the average annual erosion of the
bank or shoreline by the height and length of the shoreline protected. The largest
annual sand delivery requirement for these 10 projects is 1,100 cy/yr. If the same
method for sand calculation were used for the Sconset project area, a mitigation
volume of only 12.0 cy/lf/yr would be required.
♦ The conservative nature of the mitigation volume sand is evidenced by the
significant volumes of mitigation sand remaining in the sand template: about 17,000
cy remained after the 2016-2017 winter and about 15,000 cy remained after the
2015-2016 winter. The sand template was at its highest ever elevation in August
2017 and further addition of sand would cover vegetation and steepen the access
ramps, making equipment access and template regrading difficult or impossible. A
more adaptive approach of simply refilling the template each year to 22 cy/lf is
recommended.

The following sections provide a summary of each of the referenced monitoring reports.
4.0 Summary of Monitoring Results
4.1 Sand Delivery
As presented in the “April 2016 - December 2017 Sand Delivery and Contribution Report”
included as Attachment A, the Project incorporates a substantial mitigation volume of 22
cubic yards (cy)/linear foot (lf) /year (yr). Given the project’s length of 947 feet, the total
annual mitigation volume required is 20,834 cy.
Table 1 in Attachment A summarizes the sand deliveries and Attachment B provides a
description of the bluff monitoring results. The aerial survey of the bluff (see Section 4.2
below) indicated that not all mitigation sand was eroded over the winter and that
approximately 17,000 cy of sand remained in the template as of August 2017. The SBPF
wishes to discuss with the Commission how best to develop a more adaptive mitigation
approach, as the last few years have had lower erosion, leading to a significant portion of
the mitigation sand remaining in the sand template. The sand template is currently at its
highest elevation ever and the addition of more sand would cover up the vegetation on the
bluff face and steepen the access ramps, making pedestrian and equipment access and
template management activities (such as re-grading) more difficult or impossible.
During a meeting with the Department of Environmental Protection (DEP) in early 2017,
options for making the sand mitigation volume more adaptive to actual conditions were
discussed. DEP suggested one option may be to simply refill the template to 22 cy/lf each
spring. In this manner, whatever portion of sand that erodes each winter is replaced each
year so that a minimum of 22 cy/lf are available each year, prior to the start of the winter
storm season. SBPF believes this is a reasonable option that ensures a conservative volume
of sand is available while recognizing that actual bluff contribution rates are typically far
less than 22 cy/lf/yr.
A shown in Attachment A, after the May 2017 sand deliveries, a volume of 3,834 cy of sand
was required to refill the template to 22 cy/lf. This calculation is based on the required
mitigation volume of 20,834 cy minus the template volume of 17,000 cy = 3,834 cy. In
December 2017, SBPF delivered 2,090 cy of sand, but frigid weather prevented the delivery
of all 3,834 cy; the remaining 1,774 cy will be delivered as soon as weather permits. In this
manner, the template will be fully refilled to 22 cy/lf. As noted in the Sand Report, in order
to satisfy a strict mathematical formula of 22 cy/lf/yr without taking into account natural
variability in the erosion of the unprotected bluff or the height of the existing template,
delivery of an additional 7,033 cy would be required. While this represents a
21597/Sconset E-4 Annual Review
Epsilon Associates, Inc.
mathematical deficit under the current mitigation program, there has never been an actual
deficit in the amount of sand available. The bluff monitoring in Section 4.2 below
describes how the sand template has consistently been available and has been contributing
significantly more sand than the unprotected bluff. As noted above, SBPF wishes to discuss
the implementation of a more adaptive monitoring approach with the Commission, such as
simply refilling the template each year to 22 cy/lf, to maintain a significant volume of sand
in the template while better reflecting actual conditions and avoiding increasing the
template to an unworkable height.
4.2 Bluff Monitoring
As presented in the “Sconset Bluff August 2017 Photogrammetry Survey Report” included
as Attachment B, an aerial survey of Sconset Bluff was performed by AirShark on August 17,
2017. Unmanned aerial vehicles (“UAV”) were used to survey the bluff face and geotextile
tube area. The data from the survey were processed and used to produce a digital surface
model (DSM) of Sconset Bluff.
The survey yielded the following findings:
♦ The results of the 2017 aerial survey were also used to calculate the changes in the
bluff volume from 2013 to 2017 for those unprotected areas immediately adjacent
to the geotextile tube project (Figure 1 in Attachment B). The change in the bluff
volume in these unprotected areas was calculated from the toe of the bluff
(elevation +11 MLW) to the top of the bluff. From July 2013 to June 2017, the
unprotected areas eroded 23,717 cy. This is equivalent to a distance-weighted
average of 5.8 cy/lf/yr.
♦ As of August 2017, the volume of sand in the sand template is 17,000 cy, which is
about 18.9 cy/lf. This template volume includes the volume of sand in the sand
ramps.
♦ The Sand Report (Attachment A) and the August survey (Attachment B) show that, of
the total delivered sand volume, about 15.5 cy/lf/yr have been contributed to the
littoral system.3
♦ The Project has contributed more sand (15.5 cy/lf/yr) than the unprotected bluff (5.8
cy/lf/yr) over the last four years.
3 The volume contributed is shown in Attachment A and includes contribution from the template (including
sand ramps), erosion of bluff face above the geotextile tubes, and contribution of mitigation sand during
construction.

4.3 Shoreline Monitoring
Shoreline monitoring occurs quarterly at 46 profiles located along six miles of shoreline.
Each shoreline survey includes information on the change in the position of the shoreline
(the Mean Low Water [MLW] line) and the change in volume for each profile. Bathymetry
is conducted each spring and fall out to -25 or -35 feet MLW92 or 2,000 to 3,000 feet
offshore, whichever is farthest.
Adverse impacts from the geotextile tubes would be expected to be most apparent in the
areas immediately adjacent to the geotextile tubes. One of the purposes of the shoreline
monitoring is to ensure that the long-standing pattern of shoreline retreat in the Project area
and immediately adjacent areas is not accelerating due to the presence of the geotextile
tubes. To provide a comprehensive assessment, shoreline monitoring also occurs at profiles
farther to the north and south of the geotextile tubes that were established in the 1990’s, for
a total monitoring distance of approximately six miles.
Quarterly reports provide data for all profiles and include plots from nine beach profiles that
represent the stretch of beach subject to monitoring, to help visualize long-term trends.
These nine profiles include:
♦ Near the south of the monitoring area (Profile 84)
♦ Approximately 1,000 ft and 500 ft south of the geotubes (Profiles 90 and 90.6)
♦ Within the geotube area (Profiles 91, 91.5, and 92)
♦ Approximately 500 ft and 1000 ft north of the geotubes (Profiles 92.5 and 93)
♦ Near the north end of the monitoring area (Profile S)
Shoreline data charts from these nine representative profiles are included in the “Southwest
Nantucket Beach Monitoring, October 2017, 74th Quarterly Report” prepared by Woods
Hole Group and previously submitted to the Commission; the charts are reproduced here as
Attachment C. General observations derived from the plotted shoreline data include the
following:
♦ Each profile includes times of shoreline advance and shoreline retreat,
demonstrating a high degree of variability on short- and long-time scales. This high
degree of variability, with observed short-term periods of erosion or accretion,
suggests that adverse effects from the geotextile tubes could only be reliably
determined through years of sustained erosion that deviate from historic
observations.
♦ Each profile responds differently on variable time scales.
21597/Sconset E-6 Annual Review
Epsilon Associates, Inc.
♦ This variability does not lend itself to fitting a long-term trend line with a high
degree of statistical accuracy.
♦ The current (October 2017) shoreline position is generally similar (within about 20
feet) to the shoreline position in the ~2005-2008 timeframe.
♦ The short-term variability shown by surveys since geotube installation in January
2014 is similar to short-term variability (~2-3 year periods) observed over many
years of surveys before the geotubes were installed. Surveyed post-geotube
shoreline changes are not materially different from previous observations as related
to rates and duration of shoreline change. No accelerated erosion post-geotube
installation in excess of historical observations is evident.
4.4 Wetland Well Monitoring
As presented in “2017 Wetlands Wells Groundwater Level Monitoring” included as
Attachment D, monitoring wells were installed in June 2016 at three locations along the
western side of Baxter adjacent to the bordering vegetated wetlands (see Figure 1 in
Attachment C). Water levels in the wells were monitored three times in 2016 and in
September and October 2017. Wells were monitored in response to a concern that the
installation of the drainage system, including the catch basin at 91 Baxter Road, may impact
(lower) water levels within the wetlands. Such an impact was not expected since the catch
basin was installed across the road from the wetland and would receive only runoff from
the eastern side of Baxter Road under normal conditions. During the 2017 monitoring,
water levels in each individual well varied by about 1-4 feet. Additionally, water levels
recorded in 2017 were broadly similar to, and no deeper than, the range of water levels
measured in 2016, with no indication of a significant drop in water levels. Such variation is
within the range of expected variation (based on 50 previous well readings observed during
a 6-year period from 2001-2007 and the three readings in 2016) and correlates with
precipitation data. Accordingly, there is no evidence of harm to water levels in the wetland
from the installation of the catch basin. No further monitoring is recommended.
4.5 Underwater Video Monitoring
As presented in “Sconset Beach Underwater Video Survey Report” included as Attachment
E, on June 13, 2017, CR Environmental, Inc. (“CR”) and Epsilon conducted underwater
video surveys offshore from the geotube project site and directly adjacent areas at the base
of the bluff from 87-105 Baxter Road. Underwater video data was collected with CR’s
portable towed video sled along the transects shown on Figure 1 in Attachment E.
The survey showed that a productive habitat area is located just offshore from the geotextile
tubes, with no indication that such cobble habitat is being covered by the sand mitigation.
During the underwater video survey, fifteen invertebrate species, four fish species, and five
marine plant and algal species were observed. The dominant biota across all transects
21597/Sconset E-7 Annual Review
Epsilon Associates, Inc.
included unidentified branching brown algae, unidentified branching red algae, bread
crumb sponge, black sea bass, common skate, and rock crab. Most of the survey area had
25-54% cobble coverage, and there is no indication that such habitat is being covered by
the sand mitigation. A comparison of the 2017 survey with the two surveys conducted in
2016 survey demonstrates that results were broadly consistent and did not indicate loss of
cobble habitat due to the geotextile tubes. The required fall survey was conducted in
November 2017 and the report will be submitted within 60 days of the survey.
As described in the June 2016 report, the volume of the sand template is minimal compared
to natural sand and shoal movements. It is our ongoing recommendation that a reduction in
the frequency of underwater video monitoring is warranted, as meaningful data could only
be generated in the event that regular monitoring indicates that the sand mitigation template
is contributing several times more sand than the unprotected bluff.
4.6 Annual Drainage System Report
The function of the stormwater drainage system has been monitored in accordance with the
Stormwater Operation and Maintenance Plan. As noted in Attachment F, “The system
appears to be functioning as designed, and we do not have any immediate concerns. There
is approximately 5-inches of accumulated sediment in the base of the catch basin, which is
below the threshold for cleaning. We will continue to monitor the system.”
5.0 Recommended Changes to Monitoring and Mitigation Program
The Project’s mitigation and monitoring programs were reviewed to determine those types
of monitoring that provide the most useful data and value in assessing the potential impacts
from the geotextile tubes, and which do not. The recommended changes are the same as
presented in the December 2016 Annual Report and are summarized briefly below.
5.1 Monitoring Program Adjustments
♦ Aerial bluff monitoring should occur annually to provide an assessment of bluff
volume change in protected and unprotected areas, as well as the volume of sand
remaining in the sand template.
♦ Shoreline surveys should be adjusted to collect the most meaningful data. Three
years of quarterly surveys have now been completed.
o Shoreline monitoring frequency should be changed to a maximum of two times
a year. Analysis by WHG included in the December 2016 Annual Report
indicates that quarterly sampling and observation does not inform the analysis to
any greater degree. Therefore, a survey frequency of a maximum of two times a
year is recommended, consistent with the monitoring suggestions in the
MassDEP Beach Nourishment Best Practices Guide (MassDEP, 2007) and
recommendations from The National Research Council (National Academy
21597/Sconset E-8 Annual Review
Epsilon Associates, Inc.
Press, 1995). One survey is recommended in late winter / early spring and the
other is recommended in late summer/early fall.
o Wading shots should be eliminated from the shoreline surveys. As presented in
the December 2016 Annual Report, an analysis of extrapolating the data from 0
to -5 feet MLLW, as opposed to using a rodman to collect the data, shows that
associated errors are small (the average difference in the volume of sand
estimated for each profile was 1.1 cy/ft, which equates to a 1.4% difference)
The surveys can be completed in approximately half the time if there are no
wading shots, which would add tremendous flexibility to completing the
surveys in timely fashion, and also reduces inherent risks to the survey crew.
o Bathymetry monitoring frequency should be changed to once per year. The
December 2016 Annual Report described how bathymetry surveys conducted a
maximum of once per year are sufficient to characterize regional morphology.
Reducing the total number of bathymetry survey profiles to ~22 that extend no
more than 3,000 ft offshore would potentially allow for the survey to be
completed in a single calm sea/weather day without sacrificing substantive
information. To provide useful data for present and long-term comparisons, the
subset of ~22 profiles would include the historic whole number profiles 81
through 99 plus profiles Q, S, and W. Additionally, it is proposed that
bathymetry monitoring be re-evaluated annually to assess its continued value.
♦ Groundwater levels in wetlands wells should be discontinued. The existing
monitoring data show that there are no discernible effects from the catch basin,
results correlate with precipitation, and no ongoing impacts are anticipated.
♦ Underwater video monitoring should only be required once every three years or in
the event that regular monitoring indicates that the sand mitigation template is
contributing several (3-5) times more sand than the unprotected bluff.
♦ Drainage system reporting. The drainage system monitoring has been conducted
for two years. At this time, it is proposed that the Town Director of Public Works
monitor the catch basin for maintenance, as is done for other Town catch basins.
5.2 Mitigation Volume Adjustment
The mitigation requirement for the Project is to place a minimum of 22 cy/lf/yr annually. As
has been noted in previous submissions (see November 1, 2013 memorandum from Epsilon
Associates reproduced here as Attachment G), the average annual bank contribution
volume, calculated from 1994-2013, is 12-14.3 cy/lf/yr (depending on calculation
methodology). The conservative volume of 22 cy/lf/yr is 1.5-1.8 times the average bank
contribution.
21597/Sconset E-9 Annual Review
Epsilon Associates, Inc.
A review of ten comparable bluff and dune protection projects presented in the December
2016 Annual Report (see Attachment B) indicates that associated mitigation volumes are
mostly based upon average annual erosion of the bluff or shoreline multiplied by the height
and length of the shoreline protected. This review demonstrates that the significant
mitigation required at Sconset (equivalent to 1.5-1.8 times the bluff contribution volume) is
uniquely conservative. The conservative nature of the mitigation volume sand is evidenced
by the fact that significant volumes of mitigation sand are remaining in the sand template at
the each of each winter. In summer 2017, the volume of sand remaining in the template at
the end of the winter was approximately 17,000 cy. A substantial volume of sand (about
15,000 cy) was also available in 2016 after the end of the winter.
SBPF recommends a more adaptive mitigation program, where the full mitigation volume of
22 cy/lf will be available each year for the winter storm season, but will not be
indiscriminately placed annually regardless of how much sand remains in the template.
The proposed mitigation plan is to place the full 22 cy/lf in the sand template prior to the
start of the storm season each fall. Consistent with current practice, each time the seaward
portion of the sand cover washes away as designed during storm events, the sand template
will be re-graded (sand from the top will be pushed down) so that the geotextile tubes
remain covered and sand is available to the littoral system. Each following year (prior to the
start of the storm season), a sufficient volume of sand will be added to refill the sand
template to 22 cy/lf, so that 22 cy/lf is always available at the start of each storm season.
We believe this mitigation approach will be much more adaptive and will allow the
mitigation sand requirement to more closely mimic natural conditions.
The proposed mitigation approach recognizes that not all of sand template is washing away
each year. As noted above, in 2017, about 17,000 cy of sand remained in the template
after the storm season ended, even though the volume of sand contributed from the sand
template was higher than the volume of sand contributed from the unprotected bank. The
proposed approach avoids increasing the height of the template each year to accommodate
another full placement of 22 cy/lf even though ample sand remains, and instead simply
refills the sand to the 22 cy/lf mark each year. Continuing to increase in height of the sand
template each year is not recommended because it covers the existing bank vegetation and
steepens the access ramps, making pedestrian and equipment access and template
management activities (such as re-grading) more difficult or impossible.

ANNUAL SAND DELIVERY REPORT
1.0 Introduction
The Baxter Road and Sconset Bluff Stabilization Project (the “Project”) was constructed in
two phases. The first phase was constructed in late December 2013 and January 2014
under an Emergency Certification approval issued by the Nantucket Conservation
Commission. The first phase consisted of the installation of three stacked tiers of 45-foot
circumference geotextile tubes at the base of the eroding Sconset Bluff. The geotextile tube
installation was approximately 852 feet long and extends along the toe of the bank from 87-
105 Baxter Road. The second phase was constructed in October 2015 through February
2016 and includes the installation of a fourth tier of geotextile tubes on lots 91-99,
intermediate returns, end returns, and a surface runoff drainage system. With the returns
included, the total project length is now 947 feet.
The purpose of the annual sand delivery report is to present the sand mitigation volumes
and corresponding delivery tickets for each “Sand Year” from April 1 through March 31 of
any given year. SBPF has previously submitted detailed Sand Reports for the first three sand
years associated with the Project:
November 2013 – March 31, 2014 (referred to as the “2014 Sand Year”)
April 1, 2014 through March 31, 2015 (referred to as the “2015 Sand Year”)
April 1, 2015 through March 31, 2016 (referred to as the “2016 Sand Year”).
This report presents information on sand deliveries during the period from April 1, 2016
through May 31, 2017 (referred to as the “2017 Sand Year”).
2.0 Sand Delivery Requirements
The Project incorporates a substantial mitigation volume of 22 cubic yards(cy)/linear
foot(lf)/year(yr). Given the project’s length of 947 feet, the total annual mitigation volume
required is currently 20,834 cy. As required by the Project’s Order of Conditions (SE48-
2824), the 22 cy/lf/yr is to be placed by March 31 of any given year. Delivery tickets must
be provided annually to document the total volume of sand provided on a yearly basis.
3.0 Volume of Mitigation Sand Delivered
The following five tables document the sand delivery amounts.
Tables 1-2 present a summary of the volume of sand delivered and contributed from
December 2013 through August 2017. Table 3 presents a comparison of the
volume of sand eroded from the bluff in adjacent unprotected areas from July 2013
– August 2017.
21597/Sconset 2 2017 Annual Sand Delivery Report

Table 4 presents the volume of sand delivered during the period from December
2013 – March 31, 2014, which includes construction of the initial Project.
Table 5 presents the total volume of mitigation sand delivered during the period
from April 1, 2014 – March 31, 2015.
Table 6 presents the total volume of sand delivered during the period from April 1,
2015 – March 31, 2016, which includes supplementary construction of the fourth
tier and returns.
Table 7 presents the total volume of sand delivered during the period from April 1,
2016 – May 31, 2017.
Each of these tables is discussed in further detail below.
3.1 Table 1. Summary Volume
Lines 1-4 of Table 1 describe the total volume of sand delivered to the site, and separate this
total into the following categories: mitigation sand, sand used on the bluff face, and sand
used for construction (inside or behind the geotextile tubes). Neither sand placed on the
bluff face nor sand used for construction is counted towards the mitigation requirement.
Lines 5-11 of Table 1 provide a summary of the required mitigation volume. The base
mitigation volume is determined by multiplying 22 cy/lf/yr by the Project’s length (Line 5).
This volume is then adjusted by subtracting out the surplus sand from the previous year and
the amount of sand eroded from the bluff face. The surplus sand is calculated as that sand
delivered the previous year that is in excess of the base mitigation requirements and that is
still in the sand template at the end of the sand year (see Lines 6-8). The bluff erosion
volume accounts for that portion of the bluff face that continued to erode and is discussed
further in Section 5.0 below.
Lines 13 and 14 of Table 1 presents the final calculation of whether the project’s mitigation
requirement was met. Any surplus of sand delivered during one sand year, up to but not in
excess of the amount remaining on the sand template on the beginning of the new sand
year on April 1, is carried forward and counted towards the following year’s requirement.
3.2 Table 4. Sand Delivery December 2013 – March 31, 2014
Table 2 presents the volume of sand delivered during the period from December 2013 –
March 31, 2014, which includes construction of the initial Project. Table 2 provides a
detailed breakdown of that portion of sand placed within and behind the geotextile tubes
and presents the total volume of mitigation sand placed over, in front of, and at the ends of
the geotextile tubes. All delivery tickets for the total volume delivered of 39,204 cy were
previously submitted to the Conservation Commission, most recently as part of the 2015
Sand Report.

Table 5 presents the total volume of sand delivered during the period from April 1, 2016
through December 31, 2017 (12,640 cy, with an additional 1,744 cy scheduled for delivery

delivery of sand such that it could not occur by the usual date of March 31. Details on each
sand delivery are attached.
3.6 Summary
Table 1 shows that a surplus of sand was delivered in the Project’s first two years, with a
small deficit in the third year due to the new (reduced) estimate of bluff erosion prior to
bluff vegetation in 2015 and 2016. At the end of May 2017, while approximately 17,000
cy of sand remained in the template, there was a deficit of about 10,000 cy of sand
according to a strict mathematical formula of 22 cy/lf/yr without taking into account natural
variability in the erosion of the unprotected bluff. The SBPF wishes to discuss with the
Commission how best to handle this mathematical deficit, as the last few years have had
lower erosion, leading to a significant portion of the mitigation sand remaining in the sand
template. The sand template is currently at its highest elevation ever and the addition of
more sand would cover up the vegetation on the bluff face. At no time did the
mathematical deficit lead to an actual deficit in the amount of sand available; the sand
template has consistently been available and, as discussed below, has been contributing
more sand than the unprotected bluff.
During a meeting with the Department of Environmental Protection (DEP) in early 2017,
options for making the sand mitigation volume more adaptive to actual conditions were
discussed. DEP suggested one option may be to simply refill the template to 22 cy/lf each
spring. In this manner, whatever portion of sand that erodes each winter is replaced each
21597/Sconset 4 2017 Annual Sand Delivery Report
Epsilon Associates, Inc.
year so that a minimum of 22 cy/lf are available each year, prior to the start of the winter
storm season.
After the May 2017 sand deliveries, a volume of 3,834 cy of sand would be required to
refill the template to 22 cy/lf. This calculation is based on the required mitigation volume
of 20,834 cy minus the template volume of 17,000 cy = 3,834 cy. In December 2017,
SBPF delivered 2,090 cy of sand, but frigid weather prevented the delivery of all 3,834 cy;
the remaining 1,774 cy will be delivered as soon as weather permits. In this manner, the
template will be fully refilled to 22 cy/lf, though a mathematical deficit of 7,033 cy remains.
4.0 Annual Aerial Survey of Bluff
SBPF performed the annual aerial photogrammetry survey of the bluff on August 2017. A
separate report on the photogrammetry survey is attached (the “Sconset Bluff August 2017
Photogrammetry Survey Report” or the “2017 Survey Report”).
5.0 Changes in Bluff Volume
To understand changes in the bluff volume since project construction, the results of the
2016 survey were compared to the previous aerial photogrammetry survey of the Project
area that was conducted in July 2013. The July 2013 survey was conducted about 6
months prior to the installation of the geotextile tubes.
5.1 Changes in Bluff Volume Above Geotextile Tubes
The details on the analysis of the change in the bluff volume from 2013 to 2017 are
provided in the 2017 Survey Report. As indicated in that report, from July 2013 – August
2017 (Table 8), the change in bluff volume above the geotextile tubes was +2,794 cy. As
reported in the Project’s 2016 Annual Sand Report, a total of 7,069 cy of sand were added
to the bluff face prior to spring 2016. Of the 7,069 cy added to the bluff face, about 2,794
cy remain, as measured by the increase in bluff volume of +2,794 cy between the 2013
and 2017 surveys, indicating that approximately 4,275 cy eroded prior to vegetation efforts
in spring 2015 and spring 2016 (7094 cy of sand added – 2,794 measured in the bluff face
= 4,275 cy of sand that are believed to have eroded before the bluff was vegetated).
5.2 Changes in Bluff Volume in Adjacent Unprotected Areas
As shown in Table 3, from July 2013 to August 2017, the unprotected areas eroded 23,717
cy. This is equivalent to a distance-weighted average of 5.8 cy/lf/yr.
The 2013-2017 estimate of the loss of sand from unprotected areas of 5.8 cy/lf/yr is less
than the previously reported 2013-2016 loss of sand from unprotected areas of 12.9 cy/lf/yr.
This difference is due to the quality of the 2016 survey data. As noted in the “Sconset Bluff
August 2017 Photogrammetry Survey Report,” several lessons have been learned since the
initial survey in 2016 that improved survey accuracy in 2017. The 2013-2017 volume
change numbers are considered the most accurate. The previously-reported 2013-2016
21597/Sconset 5 2017 Annual Sand Delivery Report
Epsilon Associates, Inc.
change in bluff volume numbers are considered less accurate due to the error associated
with the vertical axis and will not be used in any further reporting.
6.0 Volume of Sand in Template
As listed in the 2017 Survey Report, the volume of the sand template was calculated by
determining the total volume of sand within the sand cover at the time of the 2017 aerial
survey, and subtracting out the known volume of sand within and behind the geotextile
tubes and returns located above beach level. The total volume of sand within the sand
cover in August 2017 was approximately 17,000 cy. There were no template regrading
events in the time interval after sand delivery and grading in May and the survey in August,
so the template volume in August is representative of the template volume at the end of the
May sand delivery.
Calculations were also performed of that portion of the sand template that is located above
the fourth tier. Per the Project’s Order of Conditions, the sand on top of the fourth tier is
not counted towards the mitigation sand. This volume is calculated as approximately 3,600
cy. It is anticipated that sand on top of the sand template, including sand on top of the
fourth tier, will continue to be pushed down to recover the geotextile tubes as needed and
hence will eventually be added to the sand volume contributed or available. In that sense,
it is a stockpile or reserve available at short notice to add to the available template.
7.0 Volume of Sand Contributed to Littoral System
Table 2 presents the approximate volume of sand contributed to the littoral system. The
amount contributed is that portion of the sand delivered to the site that is no longer in place
in the sand template and therefore is deemed to have been contributed to the littoral
system. As has been previously noted, the mitigation sand is delivered to the top of the
geotextile tubes and then pushed over to cover the face of the tubes. On an as-needed
basis throughout the winter, the sand on top of the geotextile tubes is pushed from the top
of the tubes to the face of the tubes whenever needed to recover the face of the geotextile
tubes. Table 2 has been prepared to provide a reasonable estimate of how much mitigation
sand has entered the littoral system over the past three years.
For each of the four sand years (Sand Year 2014, Sand Year 2015, Sand Year 2016, and
Sand Year 2017), this estimate was calculated by the following steps shown in Table 2:
1. Beginning with the volume of sand in the sand template at the start of each year
(this was estimated in Sand Years 2014 and 2015 and measured in Sand Years
2016 and 2017);
2. Adding the total amount of mitigation sand delivered each year (this is a known
amount for each Sand Year),
21597/Sconset 6 2017 Annual Sand Delivery Report
Epsilon Associates, Inc.
3. Subtracting the volume of sand in the sand template at the end of each year (this
was estimated in Sand Years 2014 and 2015 and measured in Sand Years 2016 and
2017);
4. Adding the bluff volume eroded (this is known as a total from 2013 through 2017
and was apportioned to Sand Years 2015 and 2016 as described above in Section
5.1),
5. Adding the volume of sand contributed during construction (this is known from
2013);
6. Determining the total volume of sand contributed (both as a total volume and as a
rate expressed in cy/lf/yr), including as an average rate from 2013-2017.
These calculations show that the Project has contributed an average of 15.5 cy/lf/yr
(although more than this has been delivered to the site). This volume is higher than the
average contribution of 5.8 cy/lf/yr of the unprotected bluff to the north and south of the
Project.

2017 ANNUAL BLUFF PHOTOGRAMMETRY SURVEY REPORT
1.0 Introduction
The Baxter Road and Sconset Bluff Stabilization Project (the “Project”) consist of three-four
tiers of geotextile tubes, vegetation planting on the bluff face, and the installation of
stormwater runoff drainage system. The Project was constructed in two phases by the
Sconset Beach Preservation Fund (“SBPF”). The first phase was constructed in late
December 2013 and January 2014 under an Emergency Certification approval issued by the
Nantucket Conservation Commission. The first phase consisted of the installation of three
stacked tiers of 45-foot circumference geotextile tubes at the base of the eroding Sconset
Bluff. The geotextile tube installation was approximately 852 feet long and extends along
the toe of the bank from 87-105 Baxter Road. The second phase was constructed in
October 2015 through February 2016 and includes the installation of a fourth tier of
geotextile tubes on lots 91-99, intermediate returns, end returns, and a surface runoff
drainage system. With the returns included, the total project length is now 947 feet.
SBPF intends to perform an annual survey of the bluff face each year, to facilitate the
calculation of the following parameters:
Annual change in volume of the bluff face above the geotubes
Annual change in volume of the unprotected bluff sections to the north and south of
the geotextile tubes.
Volume of sand in the sand template.
The 2017 photogrammetry survey described below is the second photogrammetry survey
conducted since the Project’s Order of Conditions was issued in fall 2015.
2.0 Annual Aerial Survey and Data Processing
An aerial survey of Sconset Bluff was performed by AirShark on August 17, 2017.
Unmanned aerial vehicles (“UAV”) were used to survey the bluff face and geotextile tube
area. The data from the survey were processed and used to produce a digital surface model
(DSM) of Sconset Bluff.
Sand delivery on Sconset Bluff was completed by May 31, 2017. During the period from
the last sand delivery at the end of May until the survey date of August 17, 2017, there were
no storm events that required recovering of the geotextile tubes or re-grading of the
template. Accordingly, the volume of the sand template measured during the August
survey is considered representative of the sand template volume at the end of May.
2.1 2017 Survey Details
AirShark was contracted by the SBPF to conduct UAV flights on August 17, 2017 of
Siasconset Bluff. Two different UAVs utilizing different remote sensing technologies - aerial
21597/Sconset 2 2017 Bluff Photogrammetry Survey Report
Epsilon Associates, Inc.
photogrammetry and Light Detection and Ranging (LIDAR) - were deployed to map the
bluff, geotextile tubes, and beach along Baxter Road. Photogrammetry uses high resolution
aerial photographs to derive a topographic elevation map by incorporating surveyed targets
into the post-processing data analysis. LIDAR measures distance to a target by illuminating
that target with a pulsed laser light, and measuring the reflected pulses with a sensor.
Immediately prior to the start of the surveys, Woods Hole Group and AirShark placed over
57 ground control targets on top of the bluff, on the geotubes, and along the beach that
were then surveyed in-place with the RTK GPS. AirShark provided Epsilon and Woods
Hole Group Hole Group with the photogrammetry and LIDAR data both as ArcGIS raster
shapefiles and XYZ *.csv data files. The vertical datum of the UAV data was NAVD88 (ft).
Within the UAV survey area, there are fourteen (14) historical transects included the SBPF
monitoring program that were used to ground-truth the UAV data sets. The aerial survey by
AirShark was conducted the day after the traditional two-day summer topographic survey
performed by Woods Hole Group. This ensured that a direct comparison could be made
between the topographic data and the UAV data.
Woods Hole Group compared the 2-D cross-shore profiles generated from the topographic
survey data with profiles generated from the photogrammetry and LIDAR data sets for each
of the fourteen profiles. Overall there was good agreement between the topographic data
and the UAV data sets; profiles of the topographic data matched profiles from the
photogrammetry and LIDAR surveys along the bluff and beach to an elevation of +2 to 0
MLW.
The balance of this report includes data derived from the photogrammetry survey. AirShark
reports that the vertical and horizontal accuracy associated with the photogrammetry survey
is 3-5 centimeters (cm).
2.2 2016 Data Discussion
The 2016 UAV survey was the first UAV survey conducted for the Project. Aerial mapping
using UAVs is an emerging field where techniques and methods are constantly improving.
Subsequent to the 2016 survey, additional vendors and experts were consulted in this
emerging field. It was determined that the accuracy of future UAV surveys could be
improved through the use of additional ground control points and through fine-tuning the
flight plan and data acquisition methodology. As an example, the 2017 survey included 57
ground control points whereas the 2016 survey included 11 ground control points. These
lessons resulted in improved data accuracy for the 2017 survey compared to the 2016
survey. Additionally, a new vendor (AirShark) with considerable experience was selected
for the 2017 survey.
With additional insight gained from the project’s second aerial survey, any quantities
previously calculated from the 2016 data are considered less accurate and SBPF will not
utilize these quantities in any further reporting. In particular, further review of the 2016 and
21597/Sconset 3 2017 Bluff Photogrammetry Survey Report
Epsilon Associates, Inc.
2017 data together indicated that the 2016 data were less accurate along the vertical axis
and that any quantities calculated from the 2016 data are considered estimates.
3.0 Changes in Bluff Volume
To understand changes in the bluff volume since Project construction, the results of the
2017 survey were compared to the previous aerial photogrammetry survey of the Project
area that was conducted in July 2013. The July 2013 survey was conducted about 6
months prior to the installation of the geotextile tubes.
3.1 Changes in Bluff Volume Above Geotextile Tubes
The change in the bluff volume above the geotextile tubes was calculated for the four year
period since geotextile tube installation (from July 2013- August 2017). This parameter will
be calculated annually going forward.
This calculation was performed by first generating a 3D digital surface model from the 2017
survey data of that portion of the bluff above the elevation of the geotextile tube sand cover,
which was at approximately +36 feet Mean Low Water (MLW) at the time of the August
2017 survey. Similarly, the 2013 photogrammetry survey data was used to construct a 3D
model to compare against the 2017 survey. The previous (2013) data was subtracted from
the 2017 survey data and the volumetric change was calculated in GIS based on the results.
From July 2013 – June 2017 (Table 1), the change in bluff volume above the geotextile
tubes was approximately +2,794 cy (Figure 1). As reported in the Project’s annual Sand
Report, a total of 7,069 cy of sand were added to the bluff face prior to spring 2016. Of the
7,069 cy added to the bluff face, about 2,794 cy remain, indicating that approximately
4,275 cy eroded prior to vegetation efforts in spring 2015 and spring 2016.

3.2 Changes in Bluff Volume in Adjacent Unprotected Areas
The results of the 2017 aerial survey were also used to calculate the changes in the bluff
volume from 2013 to 2017 for those unprotected areas immediately adjacent to the
geotextile tube project (Figure 1). The change in the bluff volume in these unprotected
areas was calculated from the toe of the bluff (elevation +11 MLW) to the top of the bluff.
Similar techniques were used as described in Section 3.1, and the results were used to
show the net loss between study periods.
For the north unprotected area, the section of bluff within 802 feet immediately to
the north of the geotextile tubes was used.
For the south unprotected area, the section on bluff within 192 feet immediately to
the south of the geotextile tubes was used. Areas farther south than this could not
be used because they had coir or jute terraces installed and so were not
representative of the unprotected bluff.
No areas with a bulge of sand from sand delivery activities at the accessway
between 85 and 87 Baxter Road were used in the calculations.
As shown in Table 3 this analysis indicates that the unprotected areas immediately adjacent
to the geotextile tubes eroded at the following rates:
From July 2013 to June 2017, the unprotected areas eroded 23,717 cy. This is
equivalent to a distance-weighted average of 5.8 cy/lf/yr.

2 South Unprotected Area 2,523 192 4.1 3.2
3 Total Bluff Erosion for Adjacent Unprotected Areas 23,717 5.8
The 2013-2017 estimate of the loss of sand from unprotected areas of 5.8 cy/lf/yr is less
than the previously reported 2013-2016 loss of sand from unprotected areas of 12.9 cy/lf/yr.
This difference is due to the quality of the 2016 survey data. As noted above in Section 2.2,
several lessons have been learned since the initial survey in 2016 that improved survey
accuracy in 2017. The 2013-2017 volume change numbers are considered the most
accurate. The previously-reported 2013-2016 change in bluff volume numbers are
considered less accurate due to the meaningful error margin associated with the vertical
axis and will not be used in any further reporting.

4.0 Volume of Sand in Template
The volume of the sand template was calculated by determining the total volume of sand
within the sand cover at the time of the 2017 aerial survey, and subtracting out the known
volume of sand within the geotextile tubes and returns located above beach level. The total
volume of sand within the sand cover in June 2017 was approximately 17,000 cy.
As noted above, lessons learned since the initial 2016 survey have led to greater accuracy
for the 2017 survey. Upon further review, it was determined that the initial 2016 data was
less accurate along the vertical axis, so the previous calculation of the volume of sand in the
sand template in April 2016 was re-done. A new estimate of the volume of sand in the sand
template in spring 2016 was generated by taking the 2017 sand template surface (where the
template height was an average of +35.5 feet MLW) and subtracting out 1.5 feet in
elevation (to reflect the fact that the template height was +34 feet MLW in spring April
2016), then calculating the resultant volume. This yields a revised estimate of 15,000 cy in
the sand template in April 2016.
Calculations were also performed of that portion of the sand template that is located above
the fourth tier. Per the Project’s Order of Conditions, the sand on top of the fourth tier is
not counted towards the mitigation sand. This volume is calculated as approximately 3,600
cubic yards. It is anticipated that sand on top of the sand template, including sand on top of
the fourth year, will continue to be pushed down to recover the geotextile tubes as needed.
Therefore, the volume above the fourth tier will become available through time.

3.3 LONG-TERM TRENDS
To help visualize long-term trends at select profiles along the monitoring area, a series of
figures illustrate cumulative shoreline change (feet) in shoreline position relative to a
1994 baseline position (zero on the vertical axis) over time on the horizontal axis for a
representative subset of beach profiles. The figure captions include profile-specific observations. Nine (9) beach profiles are shown in Figures 5 through 12 to represent the stretch of beach subject to monitoring including:
Near the south of the monitoring area (Profile 84)
Approximately 1,000 ft and 500 ft south of the geotubes (Profiles 90 and 90.6)
Within the geotube area (Profiles 91, 91.5 and 92)
Approximately 500 ft and 1,000 ft north of the geotubes (Profiles 92.5 and 93)
Near the north end of the monitoring area (Profile S)
Individual data points on each plot represent the change in shoreline position at mean low
water (MLW), based on the surveyed beach profile at that time. Positive numbers
indicate shoreline advance and negative numbers indicate shoreline retreat relative to the
1994 baseline (assumed zero). Blue dots represent data obtained from surveys before the installation of geotubes, while red dots represent data since geotube installation. The
plots differentiate the pre- and post-geotube installation periods as a known geographic
and temporal reference point highlighting results subject to the current regulatory
requirements, and expected to be subject to future monitoring.
The plots demonstrate temporal variability:
Periods of stability with little cumulative change in shoreline position as seen in
Figure 5 from December of 1996 to May of 2002;
Periods of shoreline advance as seen in Figure 5 from May 2002 to February 2005; and
Periods of shoreline retreat as seen in Figure 6 from December 1996 to February
2005.
General observations derived from the data plotted on Figures 5 through 13 are summarized below. This collection of long-term observations accentuates the high
degree of variability at this site:
Each profile includes times of shoreline advance and shoreline retreat,
demonstrating a high degree of variability on short and long-time scales. This high degree of variability, with observed short-term periods of erosion or
accretion, suggests that adverse effects from the geotextile tubes could only be
reliably determined through years of sustained erosion that deviate from historic
observations.
Each profile responds differently on variable time scales.
This variability does not lend itself to fitting a long-term trend line with a high
degree of statistical accuracy.

The current (October, 2017) shoreline position is generally similar (within about
20 feet) to the shoreline position in the ~2005-2008 timeframe.
The short-term variability shown by surveys since geotube installation in January
2014 is similar to short-term variability (~2-3 year periods) observed over many years of surveys before the geotubes were installed. Surveyed post-geotube
shoreline changes are not materially different from previous observations as
related to rates and duration of shoreline change. No accelerated erosion in
excess of historical observations is evident.

3.4 WAVE CONDITIONS
The 74th survey is defined by the time period of August 16, 2017 through November 1, 2017. Nearshore wave data for this time period was obtained from the Woods Hole
Oceanographic Institution’s (WHOI) Martha’s Vineyard Coastal Observatory (MVCO),
located approximately 1.5 kilometers south of Edgartown Great Pond in 12 meters of
water. The MVCO collects wave data every 20 minutes, and the data are freely available
from their website (http://www.whoi.edu/mvco/). At the location of the MVCO, waves arrive primarily from West-Southwest to East-Southeast, with the majority arriving from
the South. This is expected since the waves refract toward a shore-normal approach to
the southern-facing shoreline of Martha’s Vineyard.
Offshore wave data is obtained from the National Oceanic and Atmospheric
Administration’s (NOAA’s) National Data Buoy Center (NDBC) Station 44008, located 54 nautical miles southeast of Nantucket Island in 62.5 meters of water. NDBC Station
44008 records data for a 20-minute sampling period every hour. Both data sets were
processed to evaluate wave characteristics and storm events for the period of interest.

WETLAND WELLS MONITORING REPORT
1.0 Introduction
The Sconset Beach Preservation Fund (SBPF) is permitted under SE48-2824 to install
geotextile tubes at the base of the bluff and a catch basin at 91 Baxter Road. As part of the
Order of Conditions (SE48-2824) for the geotextile tube project, thrice annual monitoring of
water levels within the wetlands is required, as described in Special Condition 50 of the
Project’s Order of Conditions:
50. Groundwater levels within the Bordering Vegetated Wetlands adjacent to the
drainage system and Baxter Road shall be taken at the beginning, middle and end of
the growing season to determine if the drainage system is having an adverse impact
to the vegetated wetlands. If there is a change in groundwater deemed significant by
the Commission they may call for the discontinuation or removal of the system.
In order to fulfill permit requirements and assess whether the vegetated wetlands are impacted
by the project, water levels within the wetlands are being monitored. On June 28, 2016,
three monitoring wells were installed along the western side of Baxter Road (monitoring wells
E-2, E-4, and E-6R; see attached Figure 1). Well E-2 is located between wells E-4 and E-6R
and is positioned west of Baxter Road, midway along the eastern side of 90 Baxter Road’s
parcel boundary. Well E-4 was installed at 94 Baxter Road (north of the catch basin) and Well
E-6R is at 86 Baxter Road (south of the catch basin). Well locations were chosen to be
consistent with historic groundwater well monitoring locations to the greatest extent feasible
given site constraints. The well locations were reviewed with Conservation Commission staff
prior to installation.
2.0 Groundwater Level Monitoring Methodology
Water levels in the monitoring wells are measured using a small-diameter water level
indicator probe. The probe cable is marked in 0.01-foot increments and the depth to water
level is measured to the nearest hundredth of a foot and recorded on-site.
3.0 Results
Table 1 details the results of well monitoring conducted on September 1 and October 3,
2017. Water level readings are presented as elevations and depths (where the depth is
measured from the top of the monitoring well).

In all three wells, water levels were slightly higher in October than in September. A review
of rainfall data for Nantucket indicates that August precipitation was just over 5 inches and
September precipitation was just over 10 inches. The trends in the water level data appear
to correlate with the rainfall data, with water levels higher in early October after the greater
precipitation in September.
4.0 Discussion
Groundwater levels in the wetlands were monitored on over 50 occasions during a 6-year
period from 2001-2007. During this 6-year monitoring period, water levels were noted to
vary by about 2 to 5 feet in each individual well over the course of the monitoring period.
Additional wetland well monitoring in June, July, and September 2016 indicated that water
levels varied by about 1-2 feet or more.
During the wetland monitoring in 2017, water levels in each individual well varied by about
1-4 feet. Such variation is within the range of expected variation and appears to correlate
with precipitation data. Additionally, water levels recorded in 2017 were broadly similar to,
and no deeper than, the range of water levels measured in 2016, with no indication of a
significant drop in water levels. Accordingly, there is no evidence of harm to water levels in
the wetland from the installation of the catch basin. No further monitoring is recommended.

UNDERWATER VIDEO SURVEY REPORT
1.0 Introduction
On June 13, 2017, CR Environmental, Inc. (“CR”) and Epsilon Associates, Inc. (“Epsilon”) on
behalf of the Siasconset Beach Preservation Fund (“SBPF”) conducted underwater video
surveys offshore from the geotube project site at the base of the bluff from 87-105 Baxter
Road, Nantucket, MA. These geotextile tubes were installed in December 2013 and
January 2014 (with an approximate length of 852-feet) and were then expanded in
November and December 2015 to a total length of 947-feet.
As part of the Order of Conditions (SE48-2824) for the geotextile tube project, underwater
video monitoring is required as described in Special Condition 28 of the Project’s Order of
Conditions:
28. Photographs and/or video shall be taken along the transects within the project
area and the area directly adjacent to the project area. The underwater video shall
be able to characterize the bottom sediments, species present and relative
abundance including the calculating of the percent cobble where appropriate.
The purpose of the underwater video survey monitoring is to evaluate if the mitigation sand
(the “sand template”) placed on top of the geotextile tubes is causing a significant alteration
or loss of cobble/boulder habitat located directly offshore of the geotextile tubes. The June
2017 survey marks the third underwater video survey since the geotextile tubes were
installed. This document describes the data acquisition and processing methods,
equipment used on the survey, and survey results.
2.0 Vessel Operations, Navigation, and Survey Design
The underwater video monitoring survey activity was conducted on June 13, 2017 from the
35-foot fishing vessel Althea K. The vessel was configured to accommodate navigation and
video acquisition systems and was furnished with a portable generator to power survey
electronics. The survey crew on the underwater video survey consisted of a boat captain
and two mates, a field biologist, an oceanographic technician, and an environmental
scientist.
Seven shore-parallel video drift transects were conducted to visually characterize bottom
sediments, biota, and type of bottom cover offshore from the geotube project site (see the
maps in Attachment A). These transects started approximately 250 feet from the Mean Low
Water (MLW) line and extended 1,915 feet offshore. The shore-parallel transects are
referred to by their distance offshore, in feet: TR-250, TR-415, TR-725, TR-1,050, TR-1,300,
TR-1,595, and TR-1,915. Three shore-perpendicular video drift transects, which crossed the
shore-parallel transects, were also conducted just offshore from the geotextile tubes. These
three shore-perpendicular video drift transects were conducted in approximately the same
21597/Sconset Geotextile Tube Project 2 Underwater Survey Report
Epsilon Associates, Inc.
location as three previously-established shoreline survey transects that are regularly
surveyed by the Woods Hole Group. Accordingly, these three video drift transects are
referred to by the same name as the shoreline survey transects (TR-91.13, TR-91.35, and TR-
91.9).
Navigation for the survey was accomplished using a Hemisphere VS-110 12-channel sub-
meter (GPS) system. The GPS system was interfaced to a laptop computer running
HYPACK 2013A hydrographic survey software. HYPACK recorded vessel position, water
depth, and provided a steering display for the vessel captain.
The video drift transects were created in HYPACK and background imagery was imported
from a shape file showing the Woods Hole Group Shoreline Monitoring Program survey
transects.
3.0 Survey Data Acquisition and Processing
Underwater video operations were conducted using a real time high resolution color
underwater video data acquisition system permitted the characterization of bottom habitat
and the species present. Maps showing the location of the video transects offshore are
provided in Attachment A.
Underwater video data was collected with CR’s portable towed video sled consisting of a
lightweight aluminum frame, Outland Technologies’ high-resolution low light color camera,
and two wide-angle 250 watt lights with variable output control. The video camera was
cabled to the surface to an OTI-960 DVR recorder and topside monitor. The video sled was
lowered and raised by using a lifting davit and lobster pot hauler mounted on the stern and
the height of the system off the bottom was continually adjusted to achieve the best bottom
coverage and video quality. The video system was operated in “drift and tow mode” and
the vessel speed varied between 0.6 to 3 knots.
Mounted lasers on the video sled frame were used for scaling purposes, and a calibrated
scale template was overlain on the video frame or screen captures. The distance between
template grid lines in both the X and Y directions was equal to approximately 6 inches.
This grid system permitted scaling and estimating of bottom biota and determining substrate
classes and their percent coverage. When the video camera was one foot off the bottom,
the viewing area of the camera was approximately 1.5 ft x 1.5 ft (18” x 18”) and the video
quality was optimal for bottom sediment characterizations and biota identifications.
HYPACK navigation files were recorded during each video drift. Video data were
transferred to a processing computer and viewed by a staff scientist at Epsilon.
Representative screen captures (frame images) were extracted along each video transect to
characterize bottom sediments and biota offshore from the project.
21597/Sconset Geotextile Tube Project 3 Underwater Survey Report
Epsilon Associates, Inc.
To analyze the bottom characteristics of each transect, screenshots were taken at each
intersection between the seven shore-parallel and three shore-perpendicular transects. In
addition, coordinates for two previously-established, shore-perpendicular survey transects
(90.6 and 92.5) were added to the figure, then screenshots were pulled from intersections
between those two transects and the seven shore-parallel transects. No underwater video
surveys occurred along shoreline survey lines 90.6 and 92.5.
Using the GPS data collected simultaneously with the video, the coordinates and time
stamps for each of these intersections were extracted into a spreadsheet (Table 1). The
intersection coordinates were found by scrolling through the video until the time and the
live latitude and longitude reading matched as closely as possible to the GPS data
coordinates. Sometimes the view closest to the intersection point was not optimal due to
the camera position being either too far or too close to the bottom. In these instances a
screenshot was captured as close as possible to the intersect position where the view was
improved. The scale grid was overlain on the video view. Live video (not shown) was
reviewed concurrent with the screenshots for the most accurate assessment of biota and
bottom substrate.
Once the scale grid was in place, the bottom coverage was classified along a gradient of
grain sizes using the Auster hierarchical approach (Auster 1998). Bottom sediment and
habitat types within the offshore area included: flat sand, sand ripples, sand waves, pebble,
cobble, and boulder. The percent cover for bottom sediment types present in each
screenshot was approximated using the scale grid. Each of the nine grid sections was
reviewed and bottom sediment was categorized individually, then an average was
calculated for the complete screenshot. The percent bottom type numbers were rounded to
the nearest five percent for presentation in Table 1. To maintain consistency across the 35
screenshots, the same individual performed all percent cover estimates.
Each screenshot is given three identifiers. First, the intersection location is indicated by the
name of the transect, which is the same as the distance in feet from the shore. Second, the
shore-perpendicular transect that crosses the shore-parallel transect is listed. Lastly, each
screenshot is given a number in order of the time the screenshot was taken within the
transect video (for #1-21), where points run from north to south and switch to the next
transect offshore after every three points. For example, points 1-3 are ordered north to
south on transect TR-250, points 4-6 are ordered north to south on transect TR-415, and so
on. Screenshots #22-35 were taken from the intersections between the new shore-parallel
transects and the two previously-established shoreline survey shore-perpendicular transect
lines (90.6 and 92.5).
4.0 Survey Results
Table 1 provides the bottom sediment coverage and biota present in the underwater video

and biota. Screenshots 1-21 were taken at intersections between new transects, while
screenshots 22-35 used shore-perpendicular transect locations taken from the previously-
established shoreline monitoring transects.
Table 1 provides an assessment of the biota present and the bottom type at each of the 35
screenshot locations.
4.1 Biota
During the underwater video survey, fifteen invertebrate species, four fish species, and five
marine plant and algal species were observed. The dominant biota across all transects
included unidentified branching brown algae, unidentified branching red algae, bread
crumb sponge, orange encrusting bryozoan, black sea bass, and rock crab. Additional biota
observed at the transect intersections were boring sponge, common barnacle, common
slipper shell, hermit crab, invasive white tunicate, moon snail, northern star coral, sand
sponge, unidentified branching hydroid, and unidentified shell fragments. Additionally,
while either not captured or identifiable in the intersection screenshots, the following biota
were also observed during the video survey fieldwork: common skate, rockfish, scup, sea
urchin, spider crab, starfish, surf clam shell, Irish moss red algae, red dulse red algae, and
rock weed brown algae.
♦ Branching brown and red algae were abundant and were observed in the entire
survey area.
♦ Bread crumb sponge was abundant and was found in the five transects farthest
offshore: TR-725, TR-1050, TR-1300, TR-1595, and TR-1915.
♦ Rock crab was the most abundant invertebrate over the whole survey area and was
observed mostly in the offshore cobble/boulder habitats.
♦ Common skate and black sea bass were the most common fish, although skates
were not captured in the intersection screenshots. Both species were observed
sporadically in nearshore and offshore transects.
♦ Common slipper shells were common in the entire survey area, mostly beyond 700
feet offshore.
♦ Unidentified branching hydroids were common in flat areas offshore and observed
in the transects roughly starting at 700 feet offshore.
♦ Orange encrusting bryozoan were fairly common and were found in the four
transects farthest offshore: TR-1050, TR-1300, TR-1595, and TR-1915.
♦ Northern star coral was fairly common and found in TR-1050 and farther offshore.
21597/Sconset Geotextile Tube Project 5 Underwater Survey Report

♦ Invasive white tunicate was not very abundant and was observed mostly in the
offshore transects TR-1050, TR-1300, TR-1595, and TR-1915.
Overall, the June 2017 survey continues to show a biologically productive habitat area is
located just offshore from the geotextile tubes. Both the June and October 2016 surveys
had similar dominant biota to the June 2017 survey of branching brown and red algae,
bread crumb sponge, and rock crab. Besides some expected seasonal variability of the
species present, the June 2017 survey had results consistent with the dominant biota
observed in June and October 2016, and there is no indication of adverse effect on marine
biota from the geotextile tube project.
4.2 Bottom Sediment Coverage
In addition to biota, Table 1 lists the bottom coverage types observed in the survey area.
The bottom sediment categories include flat sand, sand waves, sand ripples, pebble, cobble,
and boulder. An additional category shows the cobble and boulder percent coverage
combined into one percentage. These percentages were combined in order to show a more
representative picture of the bottom substrate differences across the seven shore-parallel
transects. This combined data was used to create Figure 2, which shows the abundance of
cobble/boulder. The cobble/boulder surface was calculated using a geoprocessing tool that
interpolates a surface from points using an inverse distance weighted (IDW) technique.
The percentage of cobble/boulder coverage ranges from green gradient colors (0-24%), to
blue gradient colors (25-69%), and finally red gradient colors (70-100%) (Figure 2). The
percent cobble/boulder coverage varies significantly across the survey area, from <10% to
90%. In June 2017, most of the survey area had 25-54% cobble/boulder coverage. In
general, the survey area closest to shore has lower cobble/boulder percent coverage than
the survey areas farther offshore. The percentage of cobble/boulder is lowest closest to
shore. The percent cobble/boulder habitat broadly increases farther offshore. The highest
amount of cobble/boulder habitat (with >65% cobble/boulder) is observed at seven areas
located approximately 500 or more feet offshore, which are at intersections 6, 8, 9, 11, 13,
33, and 35. This general trend of the percentage of cobble/boulder habitat increasing with
distance offshore is expected based on the results of the June and October 2016 surveys
and past surveys conducted prior to geotextile tube construction.
A comparison was made between this June 2017 survey and the June and October 2016
survey results. An understanding of the natural variability in the nearshore environment
provides important context for interpreting results between surveys. Although the presence
of cobble/boulder habitat is widespread just offshore from the geotextile tubes, there is
significant natural variability within this habitat. As explained in the report for the October
2016 survey, the percent cobble/boulder coverage can vary by 20% or more when
reviewing video from locations even one or two seconds (which is a distance of about four-
10 feet) either before or after the intersection point selected for screenshot capture. While
each survey collects video data along similar transects, it is nearly impossible to collect
21597/Sconset Geotextile Tube Project 6 Underwater Survey Report
Epsilon Associates, Inc.
video data at absolutely identical locations between surveys, due to both minor variation in
the position of the vessel during video survey data collection and due to the occasional
need to adjust screenshot capture locations by one or two seconds in order to capture the
clearest view. Accordingly, some variation is expected in the cobble/boulder percent cover
in each survey, since each survey will represent slightly different locations.
With these considerations in mind, the results of the June 2017 survey were compared with
the previous two surveys done in June and October 2016. Following are the key findings
from this comparison:
♦ All three surveys showed that most of the sampling area had 25-54% cobble
coverage.
♦ All three surveys indicated that the nearshore survey areas had the lowest
cobble/boulder percent coverage, from <10% to 24%.
♦ The cobble/boulder cover was found to increase farther offshore. In June 2017, the
increased cobble/boulder cover started closer to shore (at about 415 feet offshore)
than in the June and October 2016 surveys (where increased cobble/boulder
coverage was observed starting around 700 feet offshore).
♦ All three surveys identified the same general areas as having the highest
concentration of cobble/boulder:
o June 2016 intersections 9, 11, 12, 15, 33, and 35 had 65-90% cobble/boulder
coverage,
o October 2016 intersections 9, 11, 15, 33, and 35 had 65-90% cobble/boulder
coverage, and
o June 2017 intersections 6, 8, 9, 11, 13, 33, and 35 had 65-85% cobble/boulder
coverage.
o While these results were generally consistent with each other, there was some
variation. As explained above, the differences in percent cobble/boulder
coverage between the three surveys are considered to be the results of natural
variability. In particular, a few locations where the percent cobble/boulder
appeared to decrease in June 2017 from previous surveys (intersections 10, 17,
20, and 35) were checked and it was determined that immediately adjacent
areas had similar cobble/boulder percentages to those observed in previous
surveys. This suggests that the apparent difference between the two 2016
surveys and the June 2017 survey reflects the slightly different locations chosen
for screenshot capture between the three surveys, and is not indicative of
extensive covering of cobble/boulder habitat by mitigation sand.
21597/Sconset Geotextile Tube Project 7 Underwater Survey Report
Epsilon Associates, Inc.
♦ In certain locations (such as intersections 1, 5, 18, 24), the cobble/boulder
percentage was higher in June 2017 than in previous surveys.
♦ Overall, the June 2017 underwater video survey indicates that a productive,
widespread cobble/boulder habitat area is located just offshore from the geotextile
tubes, and there is no indication that such habitat is being covered by the sand
mitigation.
5.0 Conclusions
An underwater video survey of the area located just offshore of the geotextile tubes and
surrounding areas was conducted in June 2017, approximately 3.5 years after the
installation of geotextile tubes at the base of the bluff. During this survey, fifteen
invertebrate species, four fish species, and five marine plant and algal species were
observed. The dominant biota across all transects included branching brown algae,
branching red algae, bread crumb sponge, and rock crab. Common skate, black sea bass,
northern star coral, and orange encrusting bryozoan were common in most of the survey
area. Besides some expected seasonal variability of the species present, the June 2017
survey continues to show a biologically productive habitat area is located just offshore from
the geotextile tubes, and there is no indication of adverse effect on marine biota from the
geotextile tube project.
The bottom sediment type was also surveyed. The percent cobble/boulder coverage varied
significantly across the survey area, from <10% to 90%, with the percentage of
cobble/boulder coverage generally increasing farther offshore from the geotextile tubes.
The June 2017 survey results were broadly consistent with the June and October 2016
survey results: most of the survey area in June 2017 had 25-54% cobble coverage, similar to
the June and October 2016 surveys, and localized areas of higher cobble coverage were
found at similar locations in all three surveys. While some variation was found between the
three surveys, an analysis of survey results described in the October 2016 survey report
showed that the percentage of cobble/boulder coverage at video locations within just a few
feet of one another could vary by up to 20-30%, indicating that much of the observed
differences between the three surveys can be attributed to natural variability. Based on the
continued prevalence of cobble/bottom habitat located directly offshore of the geotextile
tube Project, there is no evidence that cobble/boulder habitat is being covered by the
mitigation sand.
As described in the June 2016 report, the volume of the sand template is minimal compared
to natural sand and shoal movements. It is our ongoing recommendation that a reduction
in the frequency of underwater video monitoring is warranted, as meaningful data could
only be generated in the event that regular monitoring indicates that the sand mitigation
template is contributing several times more sand than the unprotected bluff.

Drainage System Monitoring
Dear Maria:
We have been monitoring the function of the stormwater drainage system near 87 Baxter Road, in
accordance with the Stormwater Operation and Maintenance Plan. The system appears to be
functioning as designed, and we do not have any immediate concerns. There is approximately 5-
inches of accumulated sediment in the base of the catchbasin, which is below the threshold for
cleaning. We will continue to monitor the system.
There is some sediment along the gutter line of Baxter Road which we recommend be swept and
removed from the area.
Please feel free to contact me with any questions or concerns regarding this matter.
Sincerely,
Nantucket Engineering & Survey, P.C.
