Yarmouth, Massachusetts
Members of the Yarmouth Conservation Commission:
On behalf of Blue Sky Towers III, LLC, and in association with ProTerra Design Group, LLC, Lucas
Environmental, LLC (LE) is pleased to submit this Request for Amended Order of Conditions (OOC)
(MassDEP File #083-2382) for the proposed Wireless Communication Facility (WCF) located at 1044
Route 28 in Yarmouth, Massachusetts. At the request of the Yarmouth Zoning Board of Appeals (ZBA), a
new design concept was approved in the ZBA Decision filed with the Town Clerk on March 3, 2026
(approved February 12, 2026). The new design consists of a shorter 93-foot steel monopole antenna tower
in lieu of the original 119.6 foot tall clock tower design to reduce the visibility of the WCF. In addition, the
WCF has been shifted 22.4 feet to the west, further into the existing tree line, within the proposed lease
area, reducing impacts within the 100-year floodplain.
Enclosed please find one (1) original hard copy of the NOI application with all attachments, one (1) hard
copy full size (24 x 36) set of plans, signed and stamped, and seven (7) hard copy 11x17 size sets of plans
(provided to scale). A link to an electronic copy of the pdf file of the application and supporting
documentation will be provided concurrently. We respectfully request that you place this matter on your
agenda for the April 2, 2026 Public Hearing.

1.0 INTRODUCTION
On behalf of Blue Sky Towers III, LLC, and in association with ProTerra Design Group, LLC, Lucas
Environmental, LLC (LE) is pleased to submit this Request for Amended Order of Conditions (OOC)
(MassDEP File #083-2382) for the proposed Wireless Communication Facility (WCF) located at 1044
Route 28 in Yarmouth, Massachusetts. At the request of the Yarmouth Zoning Board of Appeals (ZBA), a
new design concept was approved in the ZBA Decision filed with the Town Clerk on March 3, 2026
(approved February 12, 2026). The new design consists of a shorter 93-foot steel monopole antenna tower
in lieu of the original 119.6 foot tall clock tower design to reduce the visibility of the WCF. In addition, the
WCF has been shifted 22.4 feet to the west, further into the existing tree line, within the proposed lease
area, reducing impacts within the 100-year floodplain.
In this updated design, the proposed work will still occur within Land Subject to Coastal Storm Flowage
(LSCSF). There are no other wetland resource areas located on the site.
This Request for Amended OOC is submitted in accordance with the Massachusetts Wetlands Protection
Act (WPA; M.G.L. Ch. 131, Section 40) and implementing regulations (310 CMR 10.00 et seq.) and the
Town of Yarmouth Wetlands Protection Bylaw and its implementing regulations. The OOC is valid through
April 13, 2028 (original expiration date of April 13, 2026, in addition to two year extension per the
Massachusetts Permit Extension Act, as the permit was valid between the qualifying approval period of
January 1, 2023 and January 1, 2025.
The following contains a brief summary of the project revisions.
2.0 EXISTING CONDITIONS
The proposed location for a new telecommunications facility is located at 1044 Route 28 in Yarmouth,
Massachusetts (See Figure 1 – USGS Map and Figure 2 – Aerial Map). The partially developed 4.4± acre
parcel is owned by the Roman Catholic Bishop of Fall River Parish and is occupied by a church building
with associated paved driveway and parking areas. Route 28 borders the eastern frontage, Forest Road
borders the northern frontage, and Long Pond Drive borders the western frontage. Residential and
commercial properties abut the parcel to the south. Vehicular access to the property is provided by the
existing paved driveways from each frontage street.
A review of the current MassGIS data layer for the Massachusetts Natural Heritage Atlas (effective
August 1, 2021) under the Natural Heritage & Endangered Species Program (NHESP) indicates that no
portion of the Study Area is located within Estimated Habitat of Rare Wildlife or Priority Habitat of Rare
Species (See Figure 3 – NHESP Map). No Certified or Potential Vernal Pools under the jurisdiction of the
Wetlands Protection Act Regulations (310 CMR 10.00 et seq.) or the Massachusetts Endangered Species
Act (321 CMR 10.00 et seq.) are mapped by NHESP in the Study Area.

The tower and compound location for the new design will remain within the FEMA Zone X (Shaded)
“Areas of 0.2% Annual Chance Flood” per the Barnstable County Flood Insurance Rate Map 25001C0587J,
effective date of July 16, 2014. The proposed gravel access driveway and stormwater infiltration basin are
located within the FEMA Zone AE Special Flood Hazard Areas (SFHAs) Subject to Inundation by the 1%
Annual Chance Flood (100-year floodplain) where base flood elevations have been determined at 11 feet
NAVD 88 (See Figure 4 – FEMA). The new site design proposes to adjust site grades so the tower
compound and equipment area are situated above the 1% Annual Chance Flood elevation. The stormwater
BMP design remains the same as the previous submittal and will accommodate the 25-year storm event and
not contribute to flooding impacts for 100-year storm events.
The Study Area is not located within an Area of Critical Environmental Concern (ACEC), Outstanding
Resource Water (ORW), or MassDEP Wellhead Protection Area.
3.0 PROJECT REVISIONS
The WCF as described in the Notice of Intent (NOI) (MassDEP File #083-2382) proposed construction
within a 100-foot by 100-foot lease area and included a 119.6-foot-tall clock tower that was designed to
house the wireless communication antenna. The WCF was situated within a 55-foot by 60-foot (3,300
square foot) equipment compound surrounded by a six-foot tall stockade fence. The new WCF footprint is
located within the same 100-foot by 100-foot lease area, but it has been shifted 22.4 feet to the west into
the existing tree line to help reduce its visibility. In addition, a shorter 93-foot steel monopole antenna
tower, in lieu of the taller clock tower, in now proposed. The WCF will be located within a similarly sized
55-foot by 60-foot compound that houses the facility equipment. The new project design is depicted on the
enclosed Permitting Plans prepared by ProTerra, dated January 29, 2026 (provided under separate cover).
Access to the WCF will remain from the existing church parking lot, via a 12-foot wide driveway, similar
to the original design. However, the access under the new design will require a slightly longer gravel
driveway, resulting in 600 additional square feet, that has been shifted approximately 15 to 20 feet to the
south (See Figure 5 – 2022 vs 2026 Design Comparison). The new design will require an additional 1,640
square feet of tree clearing to accommodate the requested shift into the existing tree line. Total area of earth
disturbance to construct the facility with drainage improvements is approximately 12,200 square feet (See
Sheet A-3 of the Permitting Plans), as compared to the approximate 10,550 square feet under the approved
WCF design. The remainder of the WCF design remains unchanged. The new development design is
approximately 6.4% of the project parcel area. A planting plan for the area surrounding the compound has
also been provided in the Permitting Plans.
The stormwater treatment train with the new design remains the same and includes pea gravel diaphragms,
vegetated swales, a sediment forebay (pretreatment), and an infiltration basin. An appropriately designed
broad-crested weir spillway maintains a low runoff head height to reduce the likelihood of erosive flow
leaving the basin during major storm events. The treatment train has been designed to remove an average
of 80% of the TSS from the compound stormwater runoff. The above grade storage within the infiltration
basin below the outlet spillway is estimated to provide for a water quality volume using the one-inch rule.
Based on the full build-out impervious area, runoff generation at the WCF would be comparable to a TR-55
1/3-acre single family residential lot (Impervious = 30%, CN=57).

Refer to Appendix D – Stormwater Management Drainage Summary, prepared by ProTerra Design Group,
LLC, dated December 29, 2022 and revised March 4, 2026, for more detailed information.
4.0 REGULATORY COMPLIANCE
This section details the project’s compliance with the performance standards for each resource area under
the WPA and Bylaw.
4.1 Land Subject to Coastal Storm Flowage
Per the July 16, 2014 FEMA Flood Insurance Rate Map for Barnstable County (Map Number
25001C0587J), the proposed gravel access driveway and stormwater infrastructure for the new design are
located within FEMA Zone AE where base flood elevations have been determined at 11 feet NAVD 88.
Section 310 CMR 10.04 of the WPA defines LSCSF as land subject to any inundation caused by coastal
storms up to and including that caused by the 100-year storm, surge of record or storm of record, whichever
is greater. The WPA does not have performance standards for LSCSF.
Section 4.10 of the Yarmouth Wetlands Protection Bylaw Regulations define LSCSF as areas that extend
up-gradient or landward from the ocean and the ocean’s estuaries that are subject to any inundation caused
by coastal storms up to and including that caused by the 100-year storm, surge of record or storm of record,
whichever is greater. Said boundary shall be the relevant 100 year storm elevation referenced within the
latest available National Flood Hazard Layer (NFHL) Maps provided by the Federal Emergency
Management Agency. The Velocity Zone (‘V zone’, also known as ‘VE zone') is a sub-area of LSCSF, with
wave heights above 3 feet, said boundary is referenced in the NFHL. The area of Moderate Wave Action
(‘MoWa’) is a sub-area of LSCSF, with wave heights between 1.5 and 3 feet, and said boundary shall be
the Limit of Moderate Wave Action as referenced within the NFHL.
The previous WCF design has been reviewed by the Yarmouth Conservation Commission and approved
with the OOC issued on May 9, 2023. The new WCF design footprint is located in approximately the same
location as the previous design, but has been shifted 22.4 feet to the west to reduce its visibility. The gravel
access road into the compound is slightly larger, increasing by approximately 600 square feet, and shifting
to the south approximately 15 to 20 feet. The new tower location and facility compound are now situated
approximately one-foot up hill in elevation as compared to the previous design resulting in approximately
3,516 square feet of the proposed project footprint located within LSCSF under the new design. The
approved design resulted in approximately 3,844 square feet of work within LSCSF (Note that the original
NOI listed the impacts at 10,550 square feet which was the entire limit of work, not the actual amount
within the resource area). This represents a decrease of approximately 328 square feet of work within
LSCSF compared to the approved design submitted under the NOI. A such, the proposed project complies
with the Yarmouth Wetlands Protection Bylaw Regulations performance standards for LSCSF.

4.2 Stormwater Management
Per the Massachusetts Department of Environmental Protection Stormwater Management Handbook, the
Standard for a stormwater management system design to meet pre- and post-development peak discharge
rates may be waived for discharges to LSCSF. In addition, peak flows generated by the tributary drainage
basin to the stormwater management system are less than one cubic foot per second (CFS) and may be
considered de minimis in nature. Therefore, a full peak discharge analysis was not conducted at this time;
however, a Stormwater Management Drainage Summary was prepared by ProTerra Design Group, LLC,
dated December 29, 2022 and revised March 4, 2026, for more detailed information.
Prior to construction, erosion and sedimentation controls will be utilized and installed as shown on Sheet
EC-1 of the Permitting Plans, typically along the downhill side of the limit of work. At the
telecommunication compound, erosion controls will consist of staked straw bale/silt fence barriers, or Silt
Soxx (where conditions do not allow stakes to be driven). A dewatering basin (utilized if required during
construction) and concrete washout area are identified on the Permitting Plans. Erosion and sedimentation
controls shall be repaired or replaced as deemed necessary during inspection, or as directed by the contractor
or engineer.
All erosion and sediment controls will be maintained throughout construction. The contractor is responsible
for re-establishing any erosion control device that is disturbed during construction or observed to be failing.
The contractor shall notify the engineer of any deficiencies in the established erosion control measures that
may lead to unauthorized discharge or stormwater pollution, sedimentation, or other pollutants.
Unauthorized pollutants include, but are not limited to, excess concrete dumping or concrete residue, paints,
solvents, grease, fuel, lube oil, pesticides, and any solid waste materials.
5.0 SUMMARY
The WCF will enhance wireless service coverage in the Town of Yarmouth and surrounding communities.
The project has been revised to address the ZBA’s request to reduce the visibility of the WCF at 1044 Route
28 in Yarmouth, Massachusetts. The wireless communication tower has been revised to include a shorter
steel monopole design, and the facility compound has been shifted to the west further into the existing
woods on the parcel. None of the work related to the new design will involve impacts to streams, wetlands,
or the 100-Foot Buffer Zone, although it will still occur within Land Subject to Coastal Storm Flowage,
similar to the original design approved by the Conservation Commission in the OOC.
It is LE’s opinion, based on our professional education, training, and familiarity with the project site, that
the new WCF design will not have any permanent adverse effect on any interests identified in the Wetlands
Protection Act or Town of Yarmouth Wetlands Protection Bylaw and are designed to minimize adverse
effects on the local ecosystem. The basis for our opinion is as follows:
• No work is proposed within Bordering Vegetated Wetlands, Inland Bank, Bordering Land Subject
to Flooding, Land Under Water Bodies and Waterways, or other wetland resource areas, or the
associated 100-Foot Buffer Zone.

• Stormwater is being managed and treated as noted in the attached Stormwater Management
Drainage Summary.
• Erosion controls are proposed for the project to protect resource areas during construction.
The proposed design achieves the goals of the Applicant, while being sensitive to adjacent regulated
resource areas. Accordingly, the Applicant respectfully requests that the Conservation Commission
consider a finding that the proposed design is adequately protective of the interests identified in the
Wetlands Protection Act and Bylaw and issue an Amended Order of Conditions approving the project as
described in this request and as shown on the attached Permitting Plans.

RE: Wireless Communications Tower Stormwater Letter:
Applicant: Blue Sky Towers III, LLC
Site Name: South Yarmouth
Site Number: MA-5104
Site Address: 1044 Route 28
South Yarmouth, MA 02664
Commission Members:
Blue Sky Towers III, LLC (“Applicant”) proposes to construct an unmanned wireless
communications tower (WCT) and compound located in the central portion of the property
designated as Assessor’s Map 50, Lot 189.1 with a street address of 1044 Route 28 in South
Yarmouth, Massachusetts.
The Applicant sought a Special Permit from the Yarmouth Zoning Bylaw to construct a 110-foot
WCT, and the Town of Yarmouth Board of Appeals issued a Denial on September 11, 2023.
The Denial was appealed to the Massachusetts District Court by the Applicant. An Order of
Remand was issued on January 5, 2026, and the Applicant and Town of Yarmouth agreed to a
resolution by adjusting the height to a 93-foot monopole style WCT as well as slide the
compound further into the existing wooded area. On February 12, 2026, the Board of Appeals
granted the Applicant the Special Permit for the site layout as shown on the revised plans dated
January 29, 2026.
This letter is intended to provide and updated description of the proposed project’s stormwater
management system as requested by the Cape Cod Commission (CCC) Staff Report Dated
June 7, 2021 as well as provide a description of the site design amendments proposed by the
Applicant in conjunction with agreements by the Town of Yarmouth.
Background Information
Existing Conditions & Site Information
The partially developed 4.4± acre parcel is owned by the Roman Catholic Bishop of Fall River
Parish and is occupied by a church building with associated paved driveway and parking areas.
Route 28 borders the eastern frontage, Forest Road borders the northern frontage, and Long
Pond Drive borders the western frontage. Residential and commercial properties abut the
parcel to the South. Vehicular access to the property is provided by the existing paved
driveways from each frontage street.

Local zoning lists the parcel within the Business District (B2), the Hotel/Motel Overlay District 1
(HMOD1), and the Village Center Overlay District (VC3). The tower compound itself will be
within FEMA Zone X (Shaded) “Areas of 0.2% Annual Chance Flood” per Flood Insurance Rate
Map 25001C0587J, effective date of July 16, 2014.
However, the proposed gravel access driveway and stormwater features will be within FEMA
Zone AE “Special Flood Hazard Areas (SFHAs) Subject to Inundation by the 1% Annual
Chance Flood; Base Flood Elevations Determined (Land Subject to Coastal Storm Flowage, 11’
Above Mean Sea Level).” The site development proposes to adjust grades so the tower
compound and equipment area remains above the 1% Annual Chance Flood. Stormwater
BMPs will be designed to the 25-year storm event per Objective WR4 and not contribute to
flooding impacts for 100-year storm events.
On November 7, 2017, Lucas Environmental, LLC completed a site investigation through a
portion of the property to identify and delineate regulated wetland resources within and
immediately surrounding the proposed WCT. The investigation resulted in no local, state, or
federally regulated wetland resource areas within 100 feet, or perennial streams within 200 feet
of the proposed limits of work.
The soils underlying the proposed development areas of the parcel, including the tower
compound and driveway, are listed as “Carver Coarse Sand.” These soils are classified by the
USDA Natural Resources Conservation Service (NRCS) as hydrologic soil group A. Existing
soil conditions were confirmed during a geotechnical investigation by Tower Engineering
Professional, Inc. An estimated high groundwater elevation was determined to be 4.8± AMSL.
Bottom of infiltration basin is in excess of two feet above estimate high groundwater elevation.
See attached boring logs and high groundwater calculations for further detail.
See Site Plans for vicinity map and existing conditions.
Development Discussions with Regulators
Development plans were reviewed by CCC staff and a report was generated discussing the
Water Resources Goal requirements for the project. The following three objectives were
identified by of the CCC staff as pertinent to the tower project:
Objective WR1 – protect and preserve groundwater quality
Objective WR2 – protect, preserve, and restore freshwater resources
Objective WR4 – manage and treat stormwater to protect and preserve water quality
It was determined that WR1 and WR2 could be achieved by provided a stormwater
management system in a manner consistent with WR4 requirements. The stormwater system
was designed to accommodate the 25-year 24-hour storm, remove at least 80% total
suspended solids (TSS), and provide water quality treatment capacity for the first inch of
stormwater runoff using exfiltration through the permeable soils under the infiltration basin.

Proposed Improvements
Tower Compound & Access Improvements
The Applicant intends to construct the proposed WCT within a 100’x100’ square (10,000 SF)
lease area in the central portion of the undeveloped areas of the parcel. Access will follow the
existing paved driveway from Route 28 to a proposed 12’ wide gravel driveway running from the
existing pavement to the tower compound. All vehicular access will utilize the existing curb cut
off of Route 28 and will consist of one or two vehicle visits per carrier per month for inspections.
The facility itself will be constructed of a 55’x60’ (3,300 SF) fenced-in compound with a surface
consisting of 4-inch depth clean stone over filter fabric. The stone voids create a reservoir of
440± cubic feet which is equal to 1.6± inches of rainfall. A monopole tower supporting antenna
equipment will be placed on a reinforced concrete foundation below grade. Ground and tower
space will be allotted for three carriers estimated to be about 933± SF of impervious area (28%±
impervious coverage) at full build-out. Based on the full build-out impervious area, runoff
generation at this WCT would be comparable to a TR-55 1/3-acre single family residential lot
(Impervious = 30%, CN=57).
Total area of earth disturbance to construct the gravel driveway and tower compound with
drainage improvements is 12,200± SF. The small development is approximately 6.4% of the
entire parcel area.
Stormwater Management Improvements
The stormwater treatment train includes pea gravel diaphragms, vegetated swales, a sediment
forebay (pretreatment), and an infiltration basin. An appropriately designed broad-crested weir
spillway maintains a low runoff head height to reduce the likelihood of erosive flow leaving the
basin during major storm events. The treatment train has been designed to remove an average
of 80% of the TSS from the compound stormwater runoff. The above grade storage within the
infiltration basin below the outlet spillway is estimated to provide for a water quality volume
using the 1-inch rule.
Details of the facility are located within the site plans.
Per the Massachusetts Department of Environmental Protection Stormwater Management
Handbook, the Standard for a stormwater management system design to meet pre- and post-
development peak discharge rates may be waived for discharges to land subject to coastal
storm flowage. In addition, peak flows generated by the tributary drainage basin to the
stormwater management system are less than one cubic foot per second (CFS) and may be
considered de minimus in nature. Therefore, a full peak discharge analysis was not conducted
at this time.
Stormwater BMP Maintenance
The pea gravel diaphragms shall be inspected monthly and cleaned as necessary during
construction and/or after storm events of 1” or rainfall or greater. Thereafter, the pea gravel
diaphragms shall be cleaned at least once per year or as needed during the Applicant’s regular

maintenance of the site. Cleanings shall include removal of large vegetation, trash, excess
sediment accumulation, and inspection of the condition of stone.
During the construction phases of the project, the vegetated swales shall be inspected monthly
and cleaned as necessary and/or after storm events with 1” of rainfall or greater. Thereafter,
these structures shall be inspected every six months during the first year and at least twice per
year as needed during the owner’s regular maintenance of the grounds. Maintenance shall
include regularly (2-3 times a year) mowing the grass (4-6” height), cleaning sediment buildup,
and reseeding bare spots. Check for signs of rilling/gullying and repair with soil and vegetation
as needed.
The sediment forebay shall be inspected monthly and cleaned as necessary during construction
and/or after storm events with 1” or rainfall or greater. Thereafter, this structure shall be
inspected at least two times per year and cleaned as necessary or as needed during the
owner’s regular maintenance of the grounds. A fixed vertical sediment marker shall be installed
to measure the depth of accumulated sediment. Cleanings shall include mowing the perimeter
berm, removal of large vegetation and trash, removal of excess sediment accumulation, and
cleaning of outlet weir. Check for signs of rilling/gullying and repair with soil and vegetation as
needed.
During the construction phases of the project, the infiltration basin shall be inspected monthly
and cleaned as necessary and/or after storm events with 1” of rainfall or greater (if necessary).
Once the system goes online, inspections shall occur regularly for the first several months or as
required to ensure proper stabilization, function, and to ensure that the inlets and outlets remain
free of obstructions. Thereafter, this structure shall be inspected and cleaned as necessary at
least twice per year. Cleanings shall include removal of accumulated sediment and inspection
of the outlet structure. Important items to check for include differential settlement, cracking,
erosion, breakout in the embankments, tree growth on the embankments, condition of rip-rap,
sediment accumulation, health of turf, clogging of outlets, and root infestation. Water levels
should be checked and recorded against rainfall amounts to verify that the drainage system is
working properly.
The broad crested weir / energy dissipater shall be inspected monthly and cleaned as
necessary during construction and/or after storm events with 1” of rainfall or greater.
Thereafter, this structure shall be cleaned at least once per year or as needed during the
owner’s regular maintenance of the grounds. Cleanings shall include removal of vegetation,
removal of excess sediment accumulation and inspection of the weir surface.

Soil Information for All Uses
Soil Properties and Qualities
The Soil Properties and Qualities section includes various soil properties and
qualities displayed as thematic maps with a summary table for the soil map units in
the selected area of interest. A single value or rating for each map unit is generated
by aggregating the interpretive ratings of individual map unit components. This
aggregation process is defined for each property or quality.
Soil Qualities and Features
Soil qualities are behavior and performance attributes that are not directly
measured, but are inferred from observations of dynamic conditions and from soil
properties. Example soil qualities include natural drainage, and frost action. Soil
features are attributes that are not directly part of the soil. Example soil features
include slope and depth to restrictive layer. These features can greatly impact the
use and management of the soil.
Hydrologic Soil Group
Hydrologic soil groups are based on estimates of runoff potential. Soils are
assigned to one of four groups according to the rate of water infiltration when the
soils are not protected by vegetation, are thoroughly wet, and receive precipitation
from long-duration storms.
The soils in the United States are assigned to four groups (A, B, C, and D) and
three dual classes (A/D, B/D, and C/D). The groups are defined as follows:
Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly
wet. These consist mainly of deep, well drained to excessively drained sands or
gravelly sands. These soils have a high rate of water transmission.
Group B. Soils having a moderate infiltration rate when thoroughly wet. These
consist chiefly of moderately deep or deep, moderately well drained or well drained
soils that have moderately fine texture to moderately coarse texture. These soils
have a moderate rate of water transmission.
15
Group C. Soils having a slow infiltration rate when thoroughly wet. These consist
chiefly of soils having a layer that impedes the downward movement of water or
soils of moderately fine texture or fine texture. These soils have a slow rate of water
transmission.
Group D. Soils having a very slow infiltration rate (high runoff potential) when
thoroughly wet. These consist chiefly of clays that have a high shrink-swell
potential, soils that have a high water table, soils that have a claypan or clay layer at
or near the surface, and soils that are shallow over nearly impervious material.
These soils have a very slow rate of water transmission.
If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is
for drained areas and the second is for undrained areas. Only the soils that in their
natural condition are in group D are assigned to dual classes.

Depth to Any Soil Restrictive Layer
A "restrictive layer" is a nearly continuous layer that has one or more physical,
chemical, or thermal properties that significantly impede the movement of water and
air through the soil or that restrict roots or otherwise provide an unfavorable root
environment. Examples are bedrock, cemented layers, dense layers, and frozen
layers.
This theme presents the depth to any type of restrictive layer that is described for
each map unit. If more than one type of restrictive layer is described for an
individual soil type, the depth to the shallowest one is presented. If no restrictive
layer is described in a map unit, it is represented by the "greater than 200" depth
class.
This attribute is actually recorded as three separate values in the database. A low
value and a high value indicate the range of this attribute for the soil component. A
"representative" value indicates the expected value of this attribute for the
component. For this soil property, only the representative value is used.

LONG-TERM STORMWATER POLLUTION
PREVENTION PLAN and OPERATION & MAINTENANCE (O&M) PLAN
FOR RAW LAND CELL TOWER
PROJECT OVERVIEW
Blue Sky Towers III, LLC (“Applicant”) proposes to construct an unmanned wireless telecommunications
facility within a 100’x100’ [10,000 square foot (SF)] lease area in the central portion of the property
designated as Assessor’s Parcel 50-189.1 located off Route 28 in South Yarmouth, Massachusetts. The
project proposes to install a new gravel driveway/parking area from the existing paved parking lot
associated with the Our Lady of the Highway Catholic Parish. The facility itself will be constructed of a
55’x60’ (3,300 SF) fenced-in compound surfaced with clean 3/4” stone over filter fabric. A galvanized
steel monopole tower supporting antenna equipment will be placed on a reinforced concrete
foundation below grade. Ground and tower space will be allotted for up to three carriers. A common
utility area will be located at the south side of the compound. The project also includes the addition of
stormwater facilities for runoff treatment tributary to the proposed tower compound and
driveway/parking improvements.
The project seeks to avoid drainage impacts to surrounding resources by directing non-point source
sheet flow runoff through existing vegetated areas that promotes sediment removal through filtering,
absorption, and settling as the velocity of flow and resultant energy is reduced. Structural Best
Management Practices (BMPs) near the tower compound and along the gravel driveway/parking area
include pea gravel diaphragms, vegetated swales, and an infiltration basin with sediment forebay
pretreatment. The project will require disturbance of ~12,200 square feet of land.
The proposed site improvements are shown on the plans provided under separate cover entitled “South
Yarmouth; MA-5104; 1044 Route 28; South Yarmouth, MA 02664” latest revision as prepared by

CONSTRUCTION MANAGEMENT
Contractor: ________________________
Address: __________________________
_________________________________
Phone Number: ____________________
A construction manager with adequate knowledge and experience on projects of similar size and scope
shall be employed to oversee all site work related construction. The contractor shall incorporate
appropriate techniques to control sediment and erosion pollution during construction in accordance
with the Massachusetts Erosion and Sediment Control Guidelines for Urban and Suburban Areas.
Dewatering activities (if required) shall be directed towards a berm and filter sack to promote infiltration
into the ground.
EROSION CONTROL BEST MANAGEMENT PRACTICES (BMPs)
During construction, silt-laden runoff or discharge from dewatering operations (if necessary) will be
prevented from exiting the construction area untreated. Siltation barriers consisting of a filter fabric silt
fence, wood chip berms, straw bales or silt socks will be erected in advance of construction along the
down-gradient edge of all disturbed areas and maintained throughout the construction period. The
control of dust and erosion during the construction period will be managed using a number of Best
Management Practices (BMPs) described below and as shown on the Erosion Control Plan & Details
sheet (EC-1) of the Construction Drawings.
Stabilized Construction Entrance
An apron constructed of coarse aggregate over a geotextile fabric shall cover the transition between the
existing parking lot and the proposed driveway/parking area. The size and construction of the entrance
is shown on the EC-1 sheet. This entrance shall be inspected daily and maintained throughout
construction activities and optionally removed after completion.
Temporary Sediment Traps (During Construction)
Small depressions that have stormwater runoff directed into them for increase retention time that
promotes settling out of suspended solids. Tributary drainage area shall be under 1 acre. The storage
volumes should be 1,800 cubic feet per acre of tributary area. The infiltration basin near the tower
compound may not be utilized during construction as a temporary sediment trap.
Silt Fence, Reinforced with Straw Bales as Required (Compost Berms & Socks can be used as alternatives)
Silt fence or silt sock is installed at the down gradient limit of work. It should be trenched into the
ground 6” and staked without drooping. The woven fabric will allow the passage of stormwater while
filtering out suspended solids. Straw bales give added filtering and erosion control. Every 100’ two bales
or silt socks shall be placed and staked perpendicular to the fence. Straw bales shall be inert straw or
salt hay type.

Blue Sky Towers III, LLC South Yarmouth, MA
Chipping Trees & Slash Debris (wood chip berms)
Residual materials made available from tree and brush clearing and grubbing the site shall be used to
intercept and retain sediment from the disturbed areas. A temporary sediment barrier constructed of
wood chips may be installed along the perimeter of the disturbed areas. These barriers are stable and
composed of natural materials reused on-site requiring small amounts of maintenance. At the
completion of construction, the shredded or chipped wood shall be spread as ground cover to provide
stabilization over the disturbed areas.
Dewatering
Although groundwater is not anticipated, if dewatering is required, discharges shall be directed through
a settling pool or filter bag prior to discharge and infiltration into the ground. Outflow of silt-laden
runoff shall not be permitted to flow directly into resource areas. Upon completion of site stabilization,
the BMP’s and conveyance systems shall be thoroughly cleaned of silt and sediment and made ready for
the proposed operation. Discharge points shall be set back from the edge of the resource areas and
monitored by qualified personnel to ensure no impacts to resource areas and compliance with
applicable federal and state regulations. Discharges shall be free from visible floating, suspended, and
settleable solids that would impair the functions of the wetlands and downstream river.
Concrete Washout Pit
A concrete washout pit/area must be designated to receive wash water from washing of tools and
concrete mixer chutes, liquid concrete waste from dump trucks, mobile batch mixers, or pump trucks.
Concrete washout activities must be conducted in a manner that does not contribute pollutants to
surface waters or stormwater runoff. Concrete washout areas may be lined or unlined excavated pits in
the ground, commercially manufactured prefabricated washout containers, or aboveground holding
areas constructed of berms, sandbags or straw bales with a plastic liner.
ON-GOING MAINTENANCE CONTRACT
The Responsible Party shall hire appropriate staff, contract with a maintenance company, or designate a
qualified party to complete ongoing maintenance for the tower compound, access drive/parking area,
and stormwater features for the facility.
LIVING DOCUMENT PROVISIONS
This document shall be updated as necessary to reflect new procedures, technologies or requirements
over the life span of the facility. Ultimately, the Responsible Party will have the authority to implement a
plan and frequency of maintenance as required.
MAINTENANCE LOG
The Responsible Party shall develop and maintain a log of inspections, maintenance, repairs, and
disposal (including location of disposal) during the life of the project. Records shall be maintained for at
least three years and be made available to regulatory agencies in accordance with the provisions of the
Massachusetts Stormwater Handbook. A sample of such a maintenance log is provided.

Blue Sky Towers III, LLC South Yarmouth, MA
GOOD HOUSEKEEPING PRACTICES DURING CONSTRUCTION
The Responsible Party shall maintain good housekeeping practices by maintaining a clean and orderly
facility to prevent potential pollution sources from coming into contact with stormwater and degrading
water quality. This includes establishing protocols to reduce the possibility of mishandling materials or
equipment and training employees in good housekeeping techniques.
Common areas where good housekeeping practices should be followed shall include: material storage
areas, vehicle and equipment maintenance areas, and loading areas. Good housekeeping practices must
include a designated and secure location for garbage. A schedule for regular pickup and disposal of
garbage and waste materials during construction and routine inspections of containers for leaks and
structural integrity shall be developed. After construction, no trash shall be kept on-site and shall be
removed by service technicians or contractors when they leave. Portable toilets shall be installed on site
and maintained throughout construction. Excess concrete and cleanout water from redi-mix vehicles
shall be directed towards small excavations or constructed boxes for cleanup. Drainage conveyance
systems shall not be used for this purpose.
MINIMIZING EXPOSURE
The Responsible Party shall minimize exposure of potential pollutant sources from coming into contact
with precipitation and being picked up by stormwater and carried into drains and surface waters. All
materials shall be plainly labeled and stored in an appropriate container in an appropriate location. All
activities which can generate sources of contaminants shall be contained.

LONG-TERM DRIVEWAY/PARKING AREA & BMP: MAINTENANCE
The gravel driveway/parking area must be maintained during active use, after construction operations
have been completed, and after major storm events to ensure that the drainage structures are
functioning properly. Prior to final completion and full occupancy of the telecommunications facility, a
representative of the Contractor and/or Engineer shall properly instruct the user of the required
maintenance responsibilities to maintain the effectiveness of the driveway and drainage system. The
Responsible Party will implement the procedures and frequencies under their current plan and inspect
the systems as needed to maintain maximum effectiveness.
Gravel Driveway / Parking Area
During the construction of the gravel driveway/parking area, the contractor shall verify the subgrade
provides adequate strength to support the gravel base and gravel top layers. If weak or soft spots are
encountered during construction, an AASHTO Class III geotextile reinforcement or angular stone layer
shall be installed along the subgrade prior to placing any structural fill or gravel base. Groundwater can
affect the strength of the driveway subbase. In areas of cut, subdrains shall be installed and outletted to
daylight to facilitate the removal of groundwater interaction with the driveway section.
After the completion of construction, maintenance items that should be performed routinely include:
Grading and shaping the driveway surface to maintain a distinct in-sloped, out-sloped, or crown
shape to move water rapidly off the road surface
o Do not leave a berm on the side of the driveway that could channel stormwater down
the driveway
Compacting the graded driveway surface to keep a hard driving surface and prevent the loss of
fines. Replace surfacing material when needed
Removing ruts through rolling dips and water bars
Replacing and/or repairing rock armor or vegetation used for slope protection, scour protection,
or energy dissipation
Trimming roadside vegetation adequately, but not excessively, for sight distance and traffic
safety
Cleaning sediment and debris accumulation within drainage culverts
Check for slide debris and remove as needed
If snow plowing occurs, grading and shaping of the driveway surface shall be returned to the
original plan design to maintain design drainage patterns toward the stormwater BMPs
