Colonial Acres Beach Parking Lot Stormwater BMPs – Yarmouth, MA
Notice of Intent Page 1 of 10
1 INTRODUCTION
1.1 Project Overview
As part of a Coastal Zone Management (CZM) grant project, the Town of Yarmouth proposes to
install structural stormwater treatment Best Management Practices (BMP) along the southernmost
portion of Standish Way and within the Colonial Acres Beach Parking Lot to help improve water
quality. The BMPs proposed for the Colonial Acres Beach Parking Lot will consist of a porous
pavement area with subsurface storage discharging to a gravel wetland stormwater cell. These
BMPs will aid in the removal of bacteria and nitrogen from stormwater runoff before it is
discharged into Mill Creek and Lewis Bay. An existing catch basin and drainage pipes within the
Colonial Acres Beach Parking Lot will also be replaced and currently conveys untreated stormwater
runoff directly to Mill Creek and Lewis Bay. No new impervious areas are proposed as part of this
project, and its construction will result in reduced impervious area Colonial Acres Beach via
installation of permeable pavement.
1.2 Project Goals
The goals of this project are to install effective green infrastructure stormwater BMPs at high
priority locations to improve water quality within the Mill Creek and Lewis Bay system and
minimize impacts to nearby resource areas. The stormwater BMPs are designed to reduce bacteria
and nitrogen loads to the waterway, restoring aquatic habitat in the area and reducing the impacts
of stormwater there.
1.3 Project Background & Existing Conditions
Standish Way
Standish Way is a paved two lane (single lane each direction) road that provides vehicular access
to Colonial Acres Beach and the surrounding residential area. All roadway work will be
performed within the town-owned roadway and right-of-way within the limits defined in the
attached design plans (Appendix I). An existing stormwater BMP along these roadways consists
of a series of 7 HDPE leaching chambers fed by two catch basins located on either side of
Windemere Road at its intersection with Standish Way. Although infiltration BMPs can be
effective for TSS and pathogen removal, leaching chambers provide minimal nitrogen treatment.
Colonial Acres Beach Parking Lot
The Colonial Acres Beach Parking Lot provides parking for access to Colonial Acres Beach via
a pedestrian boardwalk at the southeast corner of the lot. The Parking Lot also connects Standish
Way to an existing beach access path, which provides vehicular access to both the beach itself as
well as a small marina to the west of the Parking Lot anchored along Mill Creek. Existing
stormwater infrastructure in the Colonial Acres Beach Parking Lot consists of one catch basin
that outlets untreated to Mill Creek to the west which eventually discharges to Lewis Bay.

1.4 Project Location & Wetland Conditions
Based on the locations’ existing developed/disturbed areas, stormwater source and existing
resource areas, the proposed BMPs are located within several jurisdictional areas. However,
since the entire project site is already developed, nearly all impacts related to this project are
considered temporary, as the work required for the BMP installation consists solely of
redevelopment. The exception is a small amount of work to replace the existing outfall located
due west. The proposed stormwater gravel wetland and part of the proposed porous pavement
with subsurface storage are located within the Colonial Acres Beach Parking Lot (approximate
location 41.6468, -70.2566), less than 100 feet from Colonial Acres Beach and Mill Creek. A
portion of this BMP will be located within previously developed resource areas.
The remainder of the proposed porous pavement area is located along Standish Way, with the
limits of work stretching approximately 20 feet past the intersection of Standish Way and
Windemere Road and extending approximately 20 feet along Windemere Road (approximate
location 41.6469, -70.2562), Colonial Acres Beach. A portion of this BMP will be located within
both the adjacent salt marsh’s 100-foot buffer zone and the 200-foot riverfront area. Mill Creek
is located approximately 60 feet south of the BMP and drains into Lewis Bay, which lies about
800 feet southwest of the site. The catchment area for this BMP is approximately 2.74 acres,
based on a delineation previously completed by the Town of Yarmouth. The area surrounding
the gravel wetland and porous pavement footprint is mostly residential, with a public beach to
the south. Refer to Appendix A for a site USGS locus map and Appendix B for site
photographs.
1.5 Project Abutters
Work will take place within Town owned right-of-way and at the Town-owned parking lot.
Construction on Standish Way will involve a partial replacement of the road surface and will
likely result in the partial obstruction to the roadway during this paving effort (anticipated at one
day). Construction within the Colonial Acres Beach Parking Lot will involve the resurfacing of
the entire paved area and thus will require the full closure of the Parking Lot for BMP
installation, repaving and staging purposes (anticipated at approximately 3 weeks. Parcels within
100 feet of the project areas are shown on the abutters map provided in Appendix E, along with
a certified abutters list. An abutter notification letter and certified mail receipts can be found in
Appendix F.

2 ALTERNATIVES ANALYSIS
The project considered four alternatives when determining the most effective design for a new
stormwater BMP at the Colonial Acres Beach site. These alternatives were evaluated for a
number of parameters, including level of treatment, natural resources and habitat impacts, costs,
and constructability. These alternatives are discussed below.
1. No Action – The purpose of the proposed project is to provide improved treatment of the
stormwater runoff discharging from the Colonial Acres Beach Parking Lot, in turn
improving water quality within the Lewis Bay system and protecting other natural
resources in the area. Taking no action will not help achieve any of the project goals and
will result in the continued degradation of the Lewis Bay water quality and ecosystem.
Thus, this alternative was not adopted as it would not meet the goals of the project.
2. Install Small BMP with Subsurface Chambers – This alternative will replace the existing
leaching galleys and untreated outfall discharge with a smaller set of subsurface storage
chambers and gravel wetland system in the grassy area northwest of the Parking Lot, fed
by new drain pipes connecting the three existing catch basins along Windemere Road and
within the Colonial Acres Parking Lot. As this alternative has a smaller footprint
requiring less disturbance to the wetland buffer, excavation, and construction, this
alternative can be installed at a lower cost than other alternatives, reducing the associated
budget. The amount of repaving necessary would also be greatly reduced under this
alternative, however, a smaller footprint would provide a lower level of treatment overall,
as less stormwater could pass through the system at any given time. Because stormwater
treatment is the priority of this project, this alternative was not adopted as it would not
meet the project goals.
3. Install Small BMP with Riprap Forebay This alternative will replace the existing leaching
galleys and untreated outfall discharge with a smaller riprap forebay and gravel wetland
system in the grassy area northwest of the Parking Lot, fed by new drain pipes connecting
the three existing catch basins along Windemere Road and within the Colonial Acres
Parking Lot. As this alternative has a smaller footprint requiring less disturbance to the
wetland buffer, excavation, and construction, this alternative can be installed at a lower
cost than other alternatives, reducing the associated budget. The use of a forebay as
opposed to subsurface storage provides easier access for maintenance. However, a
smaller footprint would provide a lower level of treatment overall, as less stormwater
could pass through the system at any given time. Because stormwater treatment is the
priority of this project, this alternative was not adopted as it would not meet the project
goals.

Notice of Intent Page 4 of 10
4. Install Large BMP with Porous Pavement – This alternative will replace the existing
catch basin, drainpipe and outfall in the Colonial Acres lot with a large porous pavement
and gravel wetland system for improved stormwater treatment and removal of suspended
solids and total nitrogen. The large footprint will provide the maximum amount of
stormwater treatment and storage possible for the site. The large footprint will also
require more paving and fill materials than the other alternatives, although the number of
drainpipes and storm structures necessary for operation will be greatly reduced and those
costs will be eliminated. The direct connection of the porous pavement storage chambers
to the gravel wetland will also alleviate the hydraulic difficulties caused by the high
groundwater levels because of the simpler system layout. Because this will result in the
highest level of treatment of all the alternatives, this was the selected alternative.
In conclusion, Alternative 4 would achieve the project goals to the fullest extent while remaining
cost-effective, ultimately helping to improve water quality and aquatic habitat in the Lewis Bay
system.

3 DESCRIPTION OF PROPOSED WORK
3.1 Proposed BMPs and Functionality
Stormwater runoff will first infiltrate into the proposed porous pavement and subsurface storage
from Standish Way, along with the northern portion of the Colonial Acres Parking Lot. The
subsurface storage consists of an 4-inch layer of pea stone over a 6-inch to 12-inch layer of
crushed stone, lined on the sides and bottom with an impervious liner to prevent infiltration into
native soils and contact between stormwater and groundwater.
As the subsurface storage begins to fill, the pitch of the impermeable liner below the stone layers
direct stormwater toward the entrance of the gravel wetland cell, which is located entirely within
the Parking Lot. The gravel wetland cell consists of a 3-inch layer of pea stone over a 24-inch
layer of crushed stone, also lined on the sides and bottom with an impervious liner. After passing
through the gravel cell, runoff will drain into an outlet structure before flowing through
approximately 36 feet of H-20 rated high-density polyethylene (HDPE) pipe to the new outfall
structure. Treated stormwater will then be discharged to Mill Creek and Lewis Bay.
During small storm events, all of the stormwater runoff that enters the BMP will pass through the
subsurface storage and into the subsurface gravel wetland cell. Because this cell functions as an
anaerobic bioreactor, it must be entirely self-contained and isolated from the atmosphere to
promote anoxic conditions favorable for denitrification, which occurs as stormwater flows
through the subsurface gravel wetland cell and towards the low-flow BMP outlet orifice. This
orifice is sized to slowly release stormwater from the BMP over at least a 24-hour period while
always maintaining a water level within the subsurface gravel layer.
Due to the retention time required for the gravel wetland cell to provide stormwater treatment, an
overflow bypass system is necessary in the event that a larger storm event exceeds the low-flow
orifice capacity. This overflow bypass catch basin will have a grate on top that will act as an
overflow structure to allow excess stormwater to bypass the system during large storm events.
As the subsurface storage chamber fills and exceeds storage capacity, water will flow into the
overflow grate which will drain through approximately 81 feet of H-20 rated HDPE pipe before
entering the outlet structure and then outfall into Mill Creek. This bypass system will prevent
stormwater from bubbling up through the porous pavement and causing flooding within the
Parking Lot. Details of both the section and plan views for this bypass system can be found
within the plans included in Appendix I.
Work within the Standish Way is required to complete the subsurface storage, which will also
involve pavement cuts, lining of the chamber, and gravel fill. Once the new porous pavement has
been poured, a new Cape Cod berm will also be constructed along either side of Windemere Road
to the limits of new pavement, and along either side of Standish Way extending approximately 65
feet past the limits of the porous pavement. Once completed, any additional disturbed roadway
Colonial Acres Beach Parking Lot Stormwater BMPs – Yarmouth, MA
Notice of Intent Page 6 of 10
areas will be repaved as needed.
Erosion controls will be in place for the duration of construction. Work is anticipated to be
performed in early spring to minimize environmental impacts in advance of stormwater
improvements to Standish Way and the Colonial Acres Beach Parking Lot. This timeframe will also
reduce any issues with accessibility caused by roadway closures, as Yarmouth’s population
diminishes significantly in the off season.
3.2 Protective Measures
Measures will be taken to minimize sedimentation and/or siltation into the resource areas and
corresponding buffer zones during construction activities. Implementation of accepted and usual
methods of sedimentation erosion control will be used at the site during all phases of
construction. Erosion control during construction will include but is not limited to:
• Erosion control devices will be inspected weekly and after each significant rainfall event.
Any entrapped silt or other materials will be removed;
• Erosion control devices will remain in place locally until disturbed surfaces have been
stabilized with the final vegetative cover in the area of disturbance; and
• Construction vehicle access will follow existing roadway to minimize land disturbance
and compaction.
Erosion control devices and methods will remain in place until all disturbed surfaces have
stabilized. The proposed erosion controls are shown in the project plan set provided.

4 ACTIVITIES SUBJECT TO REGULATION
4.1 Description of Resource Area Impacts
The installation of the new stormwater BMP will result in minor impacts to a wetland resource
area (salt marsh), along with disturbance within the 100-foot salt marsh buffer, the 200-foot
riverfront area, and bordering land subject to flooding (BLSF). This includes excavating for the
stormwater BMP, drainpipes, and new outfall. Because the entire project site is already
developed, all impacts related to this project are considered temporary, as the work required for
the BMP installation consists solely of redevelopment. Work within the salt marsh resource area
will be considered restorative, as it will involve the replacement of an existing outfall with an
upgraded design within the same footprint. Additionally, although the entire project lies within
the BLSF resource area, the reduction of impervious area within the project limits coupled with
the addition of subsurface storage beneath the proposed porous asphalt will provide additional
flood storage, and thus will not result in any negative impacts to BLSF.

This site is not located within any Natural Heritage and Endangered Species Program (NHESP)
habitat areas for rare wildlife or rare species, within any Areas of Critical Environmental
Concern (ACEC) or Outstanding Resource Water (ORW). It is, however, located adjacent to
NHESP priority habitats of rare species (PH) numbers 945 and 259. PH 945 is the closest of the
two, approximately 180 feet southwest of the project limits (Appendix C). Finally, as mentioned
above, according to the Federal Emergency Management Agency’s (FEMA) Flood Insurance
Rate Map, the project is located entirely within flood zone AE, which represents the 100-year
floodplain (Appendix D).
This project has been designed such that it will comply with resource area performance
standards. The intent of this project is to reduce erosion of the identified resource areas, increase
water quality through the treatment of stormwater runoff, and to protect the interests identified in
M.G.L.c.131§40.

5 DEP STORMWATER STANDARDS & REPORT
The following is an overview of project compliance with the ten stormwater standards. The
installation of the above discussed stormwater best management practices will not create
additional impervious area or stormwater volume. The completed checklist is included in
Appendix H.
Standard 1. No New Untreated Discharges
No untreated discharges proposed, no increase in impervious area. Existing
system consists of leaching catch basins and trenches; proposed gravel
bioretention cell and porous pavement with subsurface storage will result in
increased treatment of stormwater for discharge to the adjacent salt marsh along
with a significant reduction in impervious area onsite.
Standard 2. Peak Rate Attenuation
N/A – No new impervious area is proposed as part of this project; therefore, peak
rate discharge will not increase. The existing paved roadway is essentially
impermeable, and thus nearly all stormwater either drains into the leaching catch
basins or runs off the roadway. Conditions will be improved under proposed
plans with the installation of porous pavement and subsurface storage, resulting in
a reduction in impervious area.
Standard 3. Recharge
N/A – No new impervious area is proposed as part of this project. All porous
pavement and the associated subsurface storage will be lined with impermeable
liners to contain stormwater for treatment. Therefore, groundwater recharge will
remain the same.
Standard 4. Water Quality
N/A – The project will have no adverse impact to water quality, with the main
goal of improving water quality within the surrounding Lewis Bay system.
TMDLs exist for both nitrogen and pathogen loading to the waterway adjacent the
project area, and the proposed constructed stormwater wetlands BMPs are
identified by the Massachusetts Stormwater Handbook as effective at removing
nitrogen and pathogens from stormwater discharges. Additionally, proper erosion
and sediment controls shown on the plans will be installed prior to construction.
Standard 5. Land Uses with Higher Potential Pollutant Loads
N/A – The project is not located within a land use with higher potential pollutant
loads.
Standard 6. Critical Areas
Colonial Acres Beach Parking Lot Stormwater BMPs – Yarmouth, MA
Notice of Intent Page 10 of 10
N/A – The project is not in a critical area as defined in the stormwater standards.
Standard 7. Redevelopments and Other Projects Subject to the Standards Only to the
Maximum Extent Practicable
N/A – This is a redevelopment project by way of stormwater management and
drainage improvements.
Standard 8. Construction Period Pollution Prevention and Erosion and Sedimentation
Control
Project includes <1 acre of disturbance therefore not covered under the
Construction General Permit. Erosion and sedimentation measures have been
outlined above and identified on the project plans.
Standard 9. Operations & Maintenance Plan
An Operations and Maintenance Plan is attached to this application (see
Appendix G).
Standard 10. Prohibition of Illicit Discharges
No illicit discharges will be created or connected as part of this project.

Operations and Maintenance Plan – Colonial Acres Beach Parking Lot, Yarmouth MA
Gravel Bioretention Cell, Porous Pavement and Subsurface Storage Stormwater BMP
Introduction
This Operation and Maintenance (O&M) Plan is prepared for both the Subsurface Gravel Cell
Stormwater BMP and the Porous Pavement with Subsurface Storage Stormwater BMP to reduce
nitrogen and/or bacteria loadings to impaired waters as part of the Professional On-call Services to
Assist with MS4 Compliance for the Town of Yarmouth, MA.
The project is located within the Colonial Acres Beach Parking Lot and the southwest end of Standish
Way in Yarmouth, with final design plans for the project dated January 2019. The Plan is broken into
two main components:
1. A narrative that provides background information on the project and describes the BMPs; and
2. Inspection and Maintenance Plan
Project Need
The Town of Yarmouth has several waterbodies within its borders listed on the Massachusetts
Integrated List of Waters (305b/303d list) as waters impaired for total nitrogen and bacteria. Among
them, Lewis Bay has a final Total Maximum Daily Load (TMDL) for pathogens prepared December
2015, and a draft TMDL for total nitrogen prepared November 2016. This surface water supports
shellfish beds and has portions that have been only “conditionally approved” or “prohibited” from
shellfishing due to poor water quality and health reasons. This waterbody, along with contributing
tributaries, is a high-priority waterbody within Yarmouth.
As outlined in the 2003 Massachusetts Estuaries Project Embayment Restoration and Guidance for
Implementation Strategies, stormwater transports nutrients, pathogens and bacteria, metals, suspended
solids, and other constituents into embayments via point sources (e.g., stormwater outfall pipes) and
nonpoint sources (e.g., runoff from fertilizer). Nitrogen compounds are present in the stormwater and
eventually discharge into embayments. Anthropogenic sources of nitrogen carried by stormwater
include fertilizers (from agricultural, suburban, and urban areas), septic system leachate, farm animal
and pet waste, and atmospheric deposition and precipitation of nitrogen compounds from power plants
and automobiles. Septic system leachate and animal waste can also cause pathogen loading via
stormwater.
Background
The Town of Yarmouth partnered with Comprehensive Environmental Inc. (CEI) to complete design
and construction of Stormwater Best Management Practices (BMP) retrofits that can be implemented
town-wide within multiple areas. After prioritizing a number of locations and performing various site
assessments within the Town, CEI identified multiple locations with high pollutant loadings from
stormwater that would benefit from the installation of a treatment BMP, including the areas around the
Colonial Acres Beach Parking Lot. The proposed Subsurface Gravel Cell BMP construction site is
located at the southwest end of Standish Way, in the center of the Parking Lot there, on the
southwestern coast of Yarmouth within the Lewis Bay Watershed and located about 800 feet northeast
of Lewis Bay. Mill Creek, which feeds into Lewis Bay, is also located less than 100 feet southwest of
the site. Existing stormwater runoff from this area is collected in three catch basins, two of which
discharge to an existing leaching galley system, with the third discharging untreated stormwater into
Mill Creek. The existing leaching galleys are functional and aid in removing bacteria from stormwater.
They will not be altered or replaced as part of this project; instead, they will be separated via parking
lot resurfacing that will subdivide the existing watershed into two smaller ones.
Operations and Maintenance Plan – Colonial Acres Beach Parking Lot, Yarmouth MA
Gravel Bioretention Cell, Porous Pavement and Subsurface Storage Stormwater BMP
Surrounding the Subsurface Gravel Cell BMP will be a Porous Pavement area with Subsurface Storage
included, covering approximately half of the Parking Lot and extending about 80 feet northeast along
the end of Standish Way. This combination BMP will replace the existing catch basin within the Beach
Parking Lot, collecting stormwater and directing it into the Gravel Cell for treatment prior to
discharging into Mill Creek.
Project Goals
The goals of this project are to install effective green infrastructure stormwater BMPs at high priority
locations to improve water quality within the Lewis Bay system and minimize impacts to nearby
resource areas. The stormwater BMPs are designed to reduce bacteria and nitrogen loads to the
waterway, addressing TMDLs and restoring aquatic habitat in the area and reducing the impacts of
stormwater there.
Site Location & Description
The Subsurface Gravel Cell BMP and Porous Pavement with Subsurface Storage BMP site is located
at the southwest end of Standish Way and within the Colonial Acres Beach Parking Lot, on the
southwestern coast of Yarmouth within the Lewis Bay Watershed and located about 800 feet northeast
of Lewis Bay. Mill Creek, which feeds into Lewis Bay, is also located less than 100 feet southwest of
the site. Surrounding area consists of medium density residential areas served by public water supply
and onsite wastewater septic systems.
Contributing area to the BMPs are as follows:
0.92 acres impervious, 0.84 acres pervious
Soil groups at the project site are classified as Hydrologic Group “B,” consisting of course sand
consistent with soils across the Cape and likely associated with glacial outwash, and Hydrologic Group
610, consisting of beach sand associated with the bordering Colonial Acres. Groundwater depth is
located greater than 2 feet below the native ground surface based on observations within the proposed
BMP locations.

Gravel Bioretention Cell, Porous Pavement and Subsurface Storage Stormwater BMP
BMP Description
Gravel Bioretention Cell
A roadside BMP consisting of a subsurface gravel wetland will be constructed within the Colonial
Acres Beach Parking Lot. As noted by the UNH Stormwater Center, “the majority of nitrogen washoff
in parking lots occurs with the first 0.3-inch of precipitation” (Gunderson et al., 2012). Thus, due to
space constraints resulting from medium-density residential development, the adjacent Colonial Acres
Beach, and an adjacent salt marsh, the BMP sized to meet the 0.30-inch storm from the contributing
subwatershed (1.76 acres, including 0.92 acres of impervious) as opposed to the 1-inch storm typically
used for optimal design. Therefore, the BMP is currently designed to hold at least 0.3-inch of
precipitation over the contributing impervious area, with design overflow structures incorporated to
mitigate excess ponding within the BMP during peak flows.
Stormwater runoff will first enter the pervious pavement section at the end of Standish Way as it flows
down the street. As water percolates into the subsurface storage chamber below, the porous pavement
will provide pretreatment for larger sediment particles via filtration which will be removed by the
Town as part of routine maintenance. Prior to entering the BMP, stormwater will pool within the
subsurface chamber until it overtops the partial impermeable liner separating the chamber and the
gravel wetland, allowing water to be discharged into the BMP at the proper elevation.
Next, stormwater passes into the underlying gravel wetland cell consisting of an 18-inch deep zone of
crushed stone, lined on the sides and bottom with an impervious liner to prevent infiltration into native
soils and contact between stormwater and groundwater. Because this cell functions as an anaerobic
bioreactor, it must be entirely self-contained and isolated from the atmosphere to promote anoxic
conditions favorable for denitrification, which occurs as stormwater flows through the subsurface
gravel wetland cell and towards the low-flow BMP outlet orifice. This orifice is sized to slowly
release stormwater from the BMP over at least a 24-hour period while always maintaining a water
level within the subsurface gravel layer. Stormwater exits the subsurface gravel wetland cell through
the low-flow orifice and into an outlet control structure, which then discharges to the newly replaced
outfall via 29 feet of 12”, H-20 rated HDPE pipe. Treated stormwater will then be discharged from the
outfall to Mill Creek, eventually flowing into Lewis Bay.
During large storm events in which the subsurface storage chamber and gravel cell become inundated,
pooled water will percolate back up through the porous pavement at a designated low point, flowing
directly into the grated opening of an overflow catch basin located adjacent to the gravel cell. The
overflow catch basin will then discharge directly to the outlet control structure via 88 feet of 12”, H-20
rated HDPE pipe, which will then discharge to the outfall. This structure will allow the stormwater
BMP to safely and effectively pass large storm events.

1.PROVIDE A MINIMUM TUBE DIAMETER OF 12 INCHES (300mm) FOR SLOPES UP TO 50 FEET
(15.24m) IN LENGTH WITH A SLOPE RATIO OF 3H:1V OR STEEPER. LONGER SLOPES OF 3H:1V MAY
REQUIRE LARGER TUBE DIAMETER OR ADDITIONAL COURSING OF FILTER TUBES TO CREATE A
FILTER BERM. REFER TO MANUFACTURER'S RECOMMENDATIONS FOR SITUATIONS WITH
LONGER OR STEEPER SLOPES.
2.INSTALL TUBES ALONG CONTOURS AND PERPENDICULAR TO SHEET OR CONCENTRATED FLOW.
3.TUBE LOCATION MAY BE SHIFTED TO ADJUST TO LANDSCAPE FEATURES, BUT SHALL PROTECT
UNDISTURBED AREA AND VEGETATION TO MAXIMUM EXTENT POSSIBLE.
