Notice of Intent
Armstrong Kelley Park, Osterville, MA
December 2022
SSUMMARY
The Applicant, the Trustees of Reservations, proposes a plan for restoration and expansion of
the gardens and improvements to parking and circulation of the Armstrong-Kelley Park, the oldest,
privately-owned park available to the public on Cape Cod. The 8.5-acre park, located in Osterville,
MA, has been in operation since 1930. The Trustees of Reservations wishes to continue the
legacy of the park as a “garden and woodland oasis” and wants to make the park accessible to
all the public, where currently, the path network is not ADA accessible, and there is limited parking
which further limits visitation to the park.
The proposed project aims at making the park accessible to all with an onsite parking area for
visitors and ADA accessible pathways. To offset the increase in hardscape within the buffer zone
and a portion of the coastal floodplain, the Applicant proposes to install green stormwater
infrastructure systems to collect the runoff from the new access drive, parking lot, and walkways.
The Applicant will implement an erosion and sedimentation control program to protect the
downgradient resource areas prior to and during construction associated with the park
improvements. The project will impact approximately 67,743 SF of the park.
The project will occur within a portion of Land Subject to Coastal Storm Flowage and within the
100-foot buffer zone to a locally regulated isolated Vegetated Wetland. The wooden walkway that
previously traversed the isolated wetland has been removed and restored under an Administrative
Review approved by the Barnstable Conservation Commission on May 17 2022 (ADM-22029).
Temporary disturbance within the wetland has been restored with a native wetland seed mix, and
the portion of the 50-foot buffer zone has also been restored from maintained lawn to a vegetated
buffer. Additional buffer mitigation is proposed to address new hardscape within the buffer zone.
The Applicant proposes to continue invasives management within the wetland and the immediate
buffer zone as previously permitted.

11.0 I N TRODUCT ION AND BA CKG ROUN D
Armstrong-Kelley Park, an 8.5-acre
parcel located in Osterville, MA, is a
carefully curated experience through
the gardens, woodlands, and an
isolated wetland. The park was
established in the 1930s and is the
oldest and largest privately-owned
park on Cape Cod. The Park had
been owned and maintained by the
Cape Cod Horticultural Society
(CCHS) for over 90 years, until
recently, when it integrated into The
Trustees of Reservations (The
Trustees), as their twelfth public
garden. Over the 90 plus years of
ownership, the CCHS developed an
extensive park program consisting of
an arboretum, central green, garden
rooms, a boardwalk, trails, the highly
regarded attraction of Liam’s Train,
and the John Folk Water Garden which has been enjoyed by visitors and residents of Cape Cod
alike. This project aims to make the park ADA accessible, introduce stormwater amenities to
address flooding on the site and climate change, and further the horticultural vision for the site.
The Trustees are seeking to make site improvements to Armstrong Kelley Park as part of a
larger master planning initiative to improve accessibility for all throughout the site, address a
need for stormwater infrastructure, and build upon the strong horticultural identity of the park.
The proposed design aims to:
Improve access, parking, and pedestrian circulation throughout the site
Comply with ADA accessibility
Create a new circular common green
Replace existing sheds with a garage for maintenance and horticultural storage;
Establish green stormwater management practices to collect runoff from the access
road, parking, and maintenance area;
Expand the John Folk Landscape Pond to include a boardwalk that connects to the
larger path network; and
Care for existing specimen plant material as well as diversify the collection with
expanded garden beds.
Members of the CCHS continue to advise The Trustees on the park design to ensure the
continued legacy of Armstrong Kelley Park as a “garden and woodland oasis,” which aims to
preserve and enhance this unique public open space for future generations.

22.0 GEN ERA L SITE DESCRI PTION
The proposed project is located at Armstrong Kelley Park in Osterville (Barnstable), MA
(Attachment A, Figures 1 and 2). Access into the park is from Main Street via a gravel drive
that terminates in a circle drive, which is the only available parking on the site. There are only
two paths that currently lead from the circle drive into the park. One is a brick walk that leads to
the General Gavin Memorial in the center of site and the second is a boardwalk at the entrance
to the circle that traverses over the wetland in the southeast of the site and leads to the sidewalk
along Main Street. Maintained
lawn surrounds the gravel drive
and the Memorial that is planted
with more than two dozen rare
species of trees and hundreds
of rhododendrons and azaleas,
as well as other native and
ornamental species. The
planting beds begin along Main
Street and are heavily
interspersed throughout the site
connecting to the woodland in
the western portion of the park.
There is a series of boardwalks
that meander through the park.
The longest boardwalk and
woodland path network leads
from the northwest corner of
Main Street to the John Folk
Landscape Pond feature (Photo
2) as well as the Liam’s Train monument located in the far northwest corner of the park. There is
also a boardwalk in the middle of the site near two existing sheds, and a beehive area in the far
north of the site. As much of the park is currently expanses of lawn with disconnected paths and
boardwalks, the park is not currently ADA accessible.
2.1 FEMA Designation
According to the current FEMA Flood Insurance Rate Map (FEMA FIRM) for the Town of
Barnstable Community Panel 250001C0544J, effective date 7/16/2014), the majority of the
project site is mapped within Zone X: Area of Minimal Flood Hazard. The southeastern corner of
the park is mapped as Zone AE, Special Flood Hazard Areas with a Base Flood Elevation (12
feet) (Attachment A, Figures 3 and 3A).
2.2 State-listed Rare Species Habitat
According to the most recent version of the Massachusetts Natural Heritage Atlas (15th Edition,
August 1, 2021), the project site does not occur within areas of Estimated Habitat of Rare
Wildlife and Certified Vernal Pools and/or Priority Habitat of Rare Species as designated by the
Photo 2. The John Folk Landscape Pond proposed to be
enlarged.

22.3 Wetland Resource Areas
The site supports wetland resource areas, as defined under the Massachusetts Wetlands
Protection Act (M.G.L. Ch. 131 § 40), and/or the Town of Barnstable Wetlands Protection Bylaw
(Chapter 237). Resource areas occurring at or near the project site include an isolated
Vegetated Wetland and its associated buffer zones and Land Subject to Coastal Storm
Flowage. Figure 4 (Attachment A) depicts the limits of the MassGIS-identified wetland resource
areas; the extent of the delineated resource areas is shown on the Existing Conditions Plans
(see Attachment B). Field methodologies, regulatory definitions and a brief description of each
resource area encountered are provided below.
2.3.1 Resource Area Delineation Methodology
On July 14, 2021, HW staff reviewed site conditions at Armstrong-Kelley Park with the purpose
of identifying and determining the boundaries of wetland resource areas within and near the
proposed project work limits. Prior to conducting field assessments, HW reviewed existing
source data available from the Massachusetts Geographic Information Service (MassGIS) to
identify the presence of resource areas within the project area.
Field delineations were conducted in accordance with methods developed by Massachusetts
Department of Environmental Protection (MassDEP) in the handbook entitled Delineating
Bordering Vegetated Wetlands Under the Massachusetts Wetlands Protection Act (March
1995), the Massachusetts Wetlands Protection Act regulations and/or the Town of Barnstable
Wetlands Protection Bylaw (Chapter 237) and associated Wetland Protection Rules and
Regulations.
HW survey located the flagging stations using an RTK GPS unit. Resource area boundaries are
shown on the existing conditions plans. Regulatory definitions of the resource areas are
provided below:
2.3.2 Vegetated Wetland
The Town of Barnstable Conservation Commission under Chapter 237 defines Vegetated
Wetland as “any area of at least 500 square feet where surface or ground water, or ice, at or
near the surface of the ground support a plant community dominated (at least 50%) by wetland
species.”
An isolated Vegetated Wetland exists at the southeastern section of the property. The wetland
is approximately 3,530 SF and meets the regulatory definition of a Vegetated Wetland under the
local Wetlands Bylaw. Topographically, the wetland forms a bowl shape and is bound by steep
slopes on the southern and eastern edges and more shallow slopes along the western and
northern extents. Along the eastern side of the wetland, the topography rises steeply to meet
the paved driveway leading to the adjacent 656 Main Street property. On the southern side, the
slope rises steeply to meet the paved walkway along the northern side of Main Street. Along the
western and northern perimeters of the wetland the slope rises gradually towards manicured

lawn areas of Armstrong-Kelley Park. These lawn areas are interspersed with a mix of native,
non-native, and/or ornamental plants, which includes individual trees, clusters of shrubs, and
landscape beds, some of which contain wood mulch ground covers.
The isolated wetland basin is vegetated with a mix of woody and herbaceous species, which
includes natives, non-natives, and invasives. Dominant species observed in the wetland area
include native jewelweed (Impatiens capensis), arrowwood (Viburnum dentatum), poison ivy
(Toxicodendron radicans), and winterberry (Ilex verticillata), and invasive or otherwise non-
native privet (Ligustrum sp.), multiflora rose (Rosa multiflora), and white poplar (Populus alba).
Additional species observed in the wetland area include silver maple (Acer saccharinum),
slippery elm (Ulmus rubra), early azalea (Rhododendron prinophyllum), highbush blueberry
(Vaccinium corymbosum), silky dogwood (Cornus amomum), sensitive fern (Onoclea sensibilis),
and lesser periwinkle (Vinca minor).
The boardwalk that had bisected the wetland basin was removed and restored with a wetland
seed mix from New England Wetland Plants under an Administrative Review approved by the
Barnstable Conservation Commission on May 17, 2022 (ADM-22029).
The property owner has also
been issued a negative
Determination of Applicability
(DA-20027) from the Barnstable
Conservation Commission to
perform invasive plant
management in and around the
wetland basin. Historically, the
CCHS had managed invasives
in this area using hand cutting
and pulling methods. During
HW’s July 14, 2021, site visit
and prior to the Applicant’s
management, a tree crew was
observed removing several
large, mature Norway maples
(Acer platanoides) growing
between the southern edge of
the wetland basin and the paved
walkway along the north side of
Main Street. In addition to the Norway maple and privet species noted above, HW also
observed a small patch of the invasive Japanese knotweed (Fallopia japonica) at the southeast
perimeter/rim of the wetland. The Applicant proposes pursuing a more aggressive strategy for
managing invasives: cut and hand apply herbicides using Commission-approved treatment.
2.3.3 50 Foot Undisturbed Buffer Zone
The Town of Barnstable Conservation Commission under Chapter 704 defines 50 Foot
Undisturbed Buffer Zone “is that area of land extending 50 ft horizontally outward from the
Photo 3. View of isolate wetland area facing approximately south
(Main Street visible in background.)
Armstrong-Kelley Park Horsley Witten Group, Inc.
Osterville (Barnstable), Massachusetts December 2022
Page 6 of 12
boundary of resource areas. A 50 ft undisturbed buffer zone consists entirely of
unmanaged/unmaintained vegetation or long-established meadow. All of the following are
absent from a 50 ft undisturbed buffer zone: hardscape (except for permitted access paths
and/or bank access stairs), lawns, ornamental plants and shrubs, gardens of any kind. This
zone may be referred to herein as the “50 foot undisturbed buffer.”
The 50-foot buffer zone to the Vegetated Wetland consists of maintained lawn areas, landscape
planting beds, and park amenities such as benches as shown in Photo 4 below. The existing
access road is located outside of the 50-foot buffer, but within the 100-foot buffer to the isolated
wetland.
Photo 4. View of 50-foot buffer zone to isolated Vegetated Wetland (far right). The
existing buffer consists of landscape beds and maintained lawn just north of the
wetland. Note that the boardwalk shown here has been removed under an
Administrative Approval.
2.3.4 Land Subject to Coastal Storm Flowage
Land Subject to Coastal Storm Flowage (LSCSF) is defined at 310 CMR 10.04 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, which ever is greater.
The southeasternmost portion of the site is located within LSCSF, which extends to elevation 12
feet. This resource area encompasses the Vegetated Wetland as well as a portion of its 50-foot
buffer zone.

33.0 PROPOSED PRO J ECT
The Applicant proposes to realign the existing park layout for improved accessibility while
preserving as many of the existing specimen trees and shrubs as possible. The design
proposes a circular walkway at the interior of the park with a large central green that has the
General Gavin Memorial in the middle. The access road will extend from the entrance of the
park along the east side of the circular walkway and lead to a parking area in the northeast
corner of the site. A maintenance garage will be located North of the parking lot.
Two green stormwater infrastructure systems will be installed to collect runoff from the access
road, parking area, and maintenance garage area. The Applicant also proposes to expand the
John Folk Landscape Pond area by enlarging the koi pond, adding a boardwalk crossing, and
augment the surrounding landscaping. Portions of the proposed work will occur within the buffer
zone to the Vegetated Wetland.
Details of the proposed project are provided on the attached project plans, entitled “Armstrong
Kelley Park Permitting Plans, Barnstable, MA,” prepared by Horsley Witten Group, Inc. dated
December 6, 2022, and ”Armstrong-Kelley Park Public Gardens Landscape Plan,” prepared by
The Trustees’ RLA and Project Manager, Elizabeth Keary Soule, dated December 6, 2022.
3.1 Alternatives Considered
The Applicant considered alternatives to the project where work is proposed within jurisdictional
resources. These generally include the No Build proposal and the proposed project, as well as
design alternatives to the proposed park improvements.
3.1.1 No Build
The no build option will maintain the existing park layout which will preserve all existing
hardscapes and existing specimen trees and shrubs. However, the current design limits
accessibility of the park as there is limited parking and the park and existing walking trails are
not ADA compliant: the small circular entry drive serves as both the access driveway and
parking area, thereby limiting the parking available for visitors; and the lack of an interconnected
trail system limits the park users as it is not ADA accessible.
3.1.2 Alternative Park Designs
During the project planning phase, several design alternatives were considered, including one
where the proposed loop road would be placed in closer proximity to the Vegetated Wetland
and its buffer zone. This design alternative, while providing improved site circulation, was
revised to the design currently proposed to maintain a larger buffer zone to the Vegetated
Wetland.
3.1.3 Preferred Alternative and Proposed Project
The proposed project is the preferred alternative, as it focuses on creating a parking area for
visitors and establishing an interconnected path system that will make the park ADA accessible.
To offset the additional hardscape the project proposes stormwater features to manage runoff
Armstrong-Kelley Park Horsley Witten Group, Inc.
Osterville (Barnstable), Massachusetts December 2022
Page 8 of 12
from the parking lot and access road, which will also serve provide visual interest for park
visitors. The park design aims to preserve and care for as many of the existing specimen trees
as possible while diversifying the existing plant collection with material appropriate to the site.
Additional park amenities include the expansion of the existing John Folk Landscape Pond with
a boardwalk crossing and expanded perennial and woody plantings.
33.2 Affected Jurisdictional Areas
The proposed project will involve work within Land Subject to Coastal Storm Flowage, as well
as the buffer zone to the Vegetated Wetland. These resource areas are regulated under the
Massachusetts Wetlands Protection Bylaw (M.G.L. c. 131, § 40) and the Town of Barnstable
Chapter 172 Wetlands Protection Bylaw and implementing regulations. Work within or near
these areas is necessary to achieve the project goals of improved site access, and to provide
for stormwater management Table 1 below summarizes the impacts to jurisdictional areas.
Permanent alteration within the 50 to 100-foot buffer zone and 100 ft buffer zone is directly
associated with the realignment of the access drive, installation of the stormwater management
practices to collect stormwater runoff from the access drive, and creation of walkways to
improve safety and ADA accessibility for pedestrians throughout the site. A small amount of
existing hardscape within the 50 to100-foot buffer zone will also be removed.
Table 1. Summary of Jurisdictional Area Impacts
Jurisdictional Area Area (SF)
Existing Impervious Surface in 100 Foot Buffer Zone 2,533
Proposed Impervious Surface in 100 Foot Buffer Zone 4,385
Net Change in Impervious Surface in Buffer Zone 1,852
0-50 Foot Buffer Zone Mitigation Plantings (1,852 SF x3) 5,556
4.0 PROTE CTION OF RESOURCE AREA INTERESTS
The proposed site alterations will occur primarily outside of jurisdictional areas and beyond the
100-foot buffer zone to the Vegetated Wetland and LSFSC. The previously approved
Administrative Review as noted above resulted in temporary impacts associated with the
removal of the boardwalks and subsequent restoration activities that occurred within Vegetated
Wetlands, the 50-foot Buffer Zone, and the 100-foot buffer zone, as well as within LSCSF. It is
important to note that the proposed impacts associated with this Notice of Intent (NOI) will
generally occur within existing landscaped or otherwise disturbed portions of buffer zone.
The Applicant proposes several mitigation measures to protect the interests of the wetland
resources, including ongoing wetland restoration efforts, buffer zone restoration, invasive
species management, and implementation of a stormwater management system, as well as
construction related mitigation measures including implementation of an erosion and
sedimentation control program. These mitigation measures are discussed below.

44.1 On-Going Wetland Restoration
The Applicant proposes on-going wetland restoration of previous wetland impacts associated
with the removal of the boardwalk (approved under an Administrative Review). Existing invasive
material, which has significantly impacted the health and viability of the wetland will continue to
be treated and/or removed, under guidance by this Commission and Commission Administrator
as also previously approved. Proposed plantings are shown on the landscape plans.
4.2 Buffer Zone Restoration
The project, which involves the reconfiguration of a public park, and which is designed to
provide accessibility for all, is designed to meet the performance standards for work within the
buffer zone. The Applicant acknowledges the Town of Barnstable Chapter 704-3 (Regulation
Governing Activity in the 100 Ft. Buffer Zone) performance standards as follows. Pursuant to
Chapter 704, the project proposes restoration within the 50-foot buffer zone to the isolated
Vegetated Wetland. The proposed restoration involves removal of impervious surfaces and lawn
within the 50-foot buffer zone and revegetation with appropriate native wetland species.
Work within the 100-foot buffer includes the reconfiguration of the site access road, a portion of
which already occurs within the 50 to 100 foot buffer (2,533 SF). In order to reconfigure the park
to accommodate universal access for all and provide adequate parking for park users, the
project will result in a net increase in impervious surface of 1,852 SF; however, no parking is
proposed within the buffer zone. Here, where there is currently not an existing undisturbed 50-
foot buffer zone within the historic park, the regulations at 704-3C through E apply. Therefore,
the proposed mitigation plantings would require restoration of 5,556 SF within the 50-foot buffer
zone to the Vegetated Wetland. Please see the Landscape Plan for details.
While the project does not allow for full restoration of the 50-foot buffer zone, as the project site
will continue to be maintained as a public park and gardens, the Applicant proposes to remove
Armstrong-Kelley Park Horsley Witten Group, Inc.
Osterville (Barnstable), Massachusetts December 2022
Page 10 of 12
lawn from the buffer zone and replace with native and other appropriate plants for the park
setting. Proposed green infrastructure stormwater management will help to promote
groundwater recharge and improve water quality within the watershed to the wetland area.
The mitigation planting within the 50-foot buffer zone will help to restore the buffer to a more
natural state is intended to further protect the wetland interests under Ch. 237.
The mitigation planting locations are shown on the separate landscape plan prepared by The
Trustees, entitled “Armstrong-Kelley Public Gardens, Landscape Plan (Sheet L-1),” dated
December 6, 2022.
44.3 Protection of Coastal Floodzone
Currently there are no performance standards for LSCSF under the Massachusetts Wetlands
Protection Act; however, the project is designed to address the Conservation Commission’s
“Guidelines for Activities in Land Subject to Coastal Storm Flowage (LSCSF).”
Per this guidance, “Any proposed activity should not:
1. Adversely impact the ability of the V Zone and Coastal A Zone to absorb or dampen wave
impacts by reducing native vegetation and pervious areas.
Not applicable. The project is located at the upper reaches of the coastal flooding and is not
subject to direct wave action. The project will remove impervious surfaces from areas adjacent
to LSCSF and replace these with vegetation.
2. Reduce the ability of the V Zone and Coastal A Zone to buffer more inland areas from
flooding and wave damage.
Not applicable. The project is located at the upper reaches of the coastal flooding, and is not
subject to direct wave action
3. Displace or divert flood waters to other areas by building coastal engineering structures
such as retaining walls, permanent earthen berms, bulkheads, and revetments; except as
allowed by state law for parcels with residential buildings constructed prior to August 10,
1978.
Not applicable. The project does not involve the construction of coastal engineering structures.
4. Cause or create the likelihood of damage by debris to other structures on land within the
flood zone.
The proposed project will not result in additional fill within LSCSF, such that flood waters could
be displaced during a 100-year flooding event. Adjacent areas to LSCSF will be revegetated
with native plantings.
5. Cause ground or surface pollution triggered by coastal storm flowage.
Armstrong-Kelley Park Horsley Witten Group, Inc.
Osterville (Barnstable), Massachusetts December 2022
Page 11 of 12
The proposed project will not result in additional fill within LSCSF, such that ground or surface
pollution would result. In addition, the project proposes the installation of green stormwater
infrastructure, a portion of which will occur within LSCSF, will improve water quality within the
resource area and within the watershed.
6. Negate best management practices implemented for uses already permitted under
Commission regulations such as Ch. 703 private docks & piers and Ch. 704 activity in the
100 ft. buffer zone.
The project is designed to reconfigure an existing public-use park to provide universal access. A
portion of the existing impervious surfaces within LSCSF has been removed from the buffer
zone per ADM-22029, and buffer restoration was completed as part of this approval. Additional
restoration efforts and installation of stormwater management practices will further these efforts
to protect the resource areas and the buffer zone.
7. Adversely impact areas that could be suitable for the inland migration of salt marshes as
sea levels continue to rise.”
Not applicable. The project site is not located in an area adjacent to salt marshes.
44.4 Invasive Species Management
The Applicant proposes on-going invasive species management efforts within the wetland and
buffer zone as previously approved and in consultation with the Conservation Commission.
Stormwater Management
The proposed project is subject to the stormwater requirements at 310 CMR 10.05(6)(k).
Stormwater management practices for this project consist of surface green stormwater
infrastructure (GSI) bioretention facilities for pre-treatment, recharge and water quality
management designed to treat the first one inch of stormwater runoff from the proposed
impervious surfaces, an existing depression as an infiltration basin, and an underground
infiltration chamber system that provides storage for peak flow attenuation for the 2-year, 10-
year, and 100-year storms. The project is designed to meets the Massachusetts Stormwater
Management Standards.
Per the proposed stormwater management design all stormwater runoff from the proposed
impervious surfaces will flow through the GSI practices prior to infiltration. These GSI practices
have been sized to meet the water quality volume (WQV). This ensures that no untreated
stormwater runoff associated with the project will flow into the wetland area. In addition, the
design is such that no additional flows up to the 100-year storm event are discharged to the
wetland area and that all flows up to the 100-year storm event are contained within the site, to
comply with the predevelopment conditions. Details of the proposed stormwater design are
provided in the Stormwater Management Report (see Attachment C).
4.5 Erosion and Sedimentation Control
The Applicant proposes to protect adjacent resource areas beyond the limit of work by
implementing a sedimentation and erosion control program for the project. A sediment and
Armstrong-Kelley Park Horsley Witten Group, Inc.
Osterville (Barnstable), Massachusetts December 2022
Page 12 of 12
erosion control barrier consisting of siltation sock (also referred to as mulch sock or silt sock)
and/or siltation fence will be placed at the limit of work and/or as shown in the project plans.
Erosion control barriers will remain in place and will be maintained in good condition until all
work is complete and all soils have been stabilized. Details of the proposed erosion and
sedimentation control are provided in the Stormwater Management Report (see Attachment C).

SECTION 30. THIS IS BASED ON EMPIRICAL CALCULATION OF
LOAD RESPONSE, MANUFACTURER'S TESTING AND FIELD
EXPERIENCE WITH THE PIPE. AASHTO SPECIFICATIONS
SECTION 18.4.1.5 DEFINES THE MINIMUM COVER AS "ID/8 BUT
NOT LESS THAN 12 INCHES". THIS COVER IS MEASURED FROM
THE PIPE OD TO THE TOP OF A RIGID (CONCRETE) PAVEMENT
OR THE BOTTOM OF A FLEXIBLE (BITUMINOUS) PAVEMENT.
BOTH AASHTO AND ASTM, AS WELL AS MOST
MANUFACTURERS, REQUIRE ADDITIONAL (TEMPORARY
