April 5, 2021
Introduction
This document is the Final Scope for the Draft Environmental Impact Statement (DEIS) for a site
plan application to the Town of Southold Planning Board that includes the development of two boat
storage buildings of 52,500 square feet (sq. ft.) and 49,000 sq. ft., along with associated
improvements including water supply, sewage disposal, site grading and drainage, landscaping and
lighting, to support the existing operations of the Strong's Yacht Center. The proposed development
would be situated on a 32.96±-acre parcel located on the west side of Mattituck Creek,which is zoned
Marine I1 (M-II) and Residential Low-Density A (R-80). All development is proposed to occur on
the portion of the site zoned M-II. The subject property is designated Suffolk County Tax Map
(SCTM)Nos. 1000-106-6-10 and 13.4.
The proposed action is subject to permits and approvals from the Town of Southold Planning Board
(site plan), Town of Southold Trustees (Wetlands Permit), Suffolk County Department of Health
Services (SCDHS) (Water Supply and Sanitary Disposal), and New York State Department of
Environmental Conservation (NYSDEC) (State Pollution Discharge Elimination System [SPDES]
Permit for Stormwater Discharges from Construction Activity). The proposed application has been
reviewed by the NYSDEC and has received an Article 25 (Tidal Wetlands)Permit for select regulated
project components and a Non-Jurisdictional determination for all work landward of the 10-foot
contour, by permit dated January 31, 2020 (Permit ID 1-4738-01843/0028). The permit, however,
was granted prior to the Positive Declaration under SEQRA. The proposed application has been
reviewed by Suffolk County Water Authority (SCWA) and the availability of water has been
determined through an extension of the water main. The Suffolk County Planning Commission
(SCPC) has General Municipal Law planning review authority over the proposed action. Utility
service connections are also required from PSEG Long Island and National Grid.
The proposed application was filed with the Town Building Department on August 27, 2018. A
Notice of Disapproval requiring site plan review before the Town Planning Board was issued on
September 18, 2018. Subsequent to the filing of the application and the Notice of Disapproval, and
at the request of the Town Planning staff, the Applicant attended a work session with the Town
Planning Board on October 15, 2018. The Applicant continued to provide additional project
information in 2018 and 2019.

Final Scope for Final Environmental Impact Statement
Strong's Yacht Center—Proposed Boat Storage Buildings
Matlituck, Town of Southold,NY
On February 10,2020,the Planning Board classified the action as Type I and commenced coordinated
review with the involved agencies. After review of Part 1 of the Full Environmental Assessment
Form (FEAF) and materials transmitted thereafter, the Planning Board caused to be prepared Part 2
and Part 3/Detemlination of Significance and identified one or more significant adverse impacts that may
result from the proposed project. On August 10, 2020, a Positive Declaration was issued by the
Planning Board, as lead agency.
To ensure that the DEIS will address all significant issues, in accordance with the New York State
Environmental Quality Review Act (SEQRA) regulations set forth at 6 NYCRR §617.8, formal
scoping is being undertaken. This Final Scope provides a description of the proposed action and the
proposed content for the DEIS, based upon the FEAF Part 2 and FEAF Part 3/Determination
of Significance, as prepared by the Town Planning Board. This Final Scope has been prepared in
accordance with 6 NYCRR §617.8(e) and sets forth the following:
• Brief description of the proposed action;
• Potentially significant adverse impacts;
• Extent and quality of information needed to adequately address potentially significant adverse
impacts;
• Initial identification of mitigation measures; and
• Reasonable alternatives to be considered.
The proposed organization and overall content of the DEIS is also included herein.
Brief Descrl )tirrn of the llt .)g ed Proje t
The proposed action includes the construction of two boat storage buildings of 52,500 SQ. FT. and
49,000 SQ. FT. to support the operations of the Strong's Yacht Center,with associated improvements
including gravel-based driveways and parking areas, water supply, sewage disposal, site grading and
drainage, landscaping and lighting. Also proposed is the removal of a pool and patio.
The Strong's Yacht Center is situated on a 32.96±-acre parcel located south of Old Mill Road and on
the west side of Mattituck Creek on lands zoned M-II (approximately 16.46 acres) and R-80
(approximately 16.5 acres). Prior to its purchase by Strong's in April 2017, the subject site was
known as the Mattituck Inlet Marina and Shipyard which existed as a frill-service marina,
maintenance, repair and storage operation for over 60 years. As illustrated on the proposed site
development plans prepared by Young & Young, the subject property is currently comprised of 40
boat slips with associated ramps and fueling and developed with eight buildings to support the
operation of the marina, as well as the sale, maintenance, dockage and storage of boats. The eight
existing buildings include the following:
• Building l: One-story residence (1,610 SQ. FT.)
• Building 2: Two-story office (2,702 SQ. FT.)
2
Final Scope for Final Environmental Impact Statement
Strong's Yacht Center—proposes'Boat Storage Buildings
Mattituck, Town of Southold, NY
• Building 3: One-story storage (17,320 SQ. FT.)
• Building 4: One-story storage (169 SQ. FT.)
• Building 5: One-story storage (341 SQ. FT.)
• Building 6. One-story storage (10,766 SQ. FT.)
• Building 7: One-story storage (15,076 SQ. FT.)
• Building 8: One-story storage (22,425 SQ. FT.)
The two proposed buildings would become Building 9 (49,000 SQ. FT.) and Building 10 (52,500 SQ.
FT.). Upon implementation of the proposed action, the total gross floor area of all buildings would
increase from 69,245 SQ. FT. to 171,929 SQ. FT.
The proposed buildings would be situated to the west of Buildings 7 and 8, which would allow direct
access and transport of yachts from the existing lift station to each of the proposed buildings. The
purpose of the proposed action is to provide indoor and heated winter storage for yachts that utilize
local waters in the peak season but are required to be transported to warmer climates in the winter
months due to a lack of adequate storage in the Town of Southold and across the entire east end of
Long Island. Based upon an average yacht size of 60 feet, it is estimated that approximately 88 yachts
could be stored within the proposed buildings during the winter months; all of which would arrive to
the site via Mattituck Inlet (as confirmed by surveys and soundings for the entire Inlet). It is also
expected that maintenance and repair activities for larger vessels would occur on the subject property,
having direct access from the Mattituck Inlet via the existing lift, further supporting a demand of the
existing local boating market. There are approximately 13 full-time staff at the Strong's Yacht Center
and, upon implementation of the proposed action, the Applicant expects to create an additional 15
career positions.
The subject parcel is adjacent to Federal and State-regulated Tidal Wetlands (Mattituck Creek), with
a portion of the site located within a 100-year floodplain (Zone AE: Elevation 8). The proposed
buildings would be constructed in a portion of the site located within a 500-year floodplain (Zone X)
at Elevation 10.0. The proposed action has been reviewed and approved by the NYSDEC by permit
dated January 31, 2020,however this permit was granted prior to the proposed action being classified
under SEQRA as a Type I action and receiving a positive declaration from the Lead Agency.
Additional review from the NYSDEC tidal wetlands permitting agency may be required.
Due to significant grade changes on the site, the proposed project will require approximately 134,000
cubic yards of cut for the placement of the proposed buildings at Elevation 10.0. The proposed
excavation plan includes two routes for truck movements and would occur over a projected duration
of approximately seven (7) months based upon loads of 30 cubic yards per truck and six-day work
weeks. An additional six months is projected to complete the proposed project, inclusive of the
retaining wall, infrastructure and two buildings (i.e., total construction duration is 13 months).
The proposed plan includes the installation of a concrete and evergreen retaining wall along the west
side of Buildings 9 and 10 and along the north side of Building 10, which serves to both stabilize the
slope as well as enhance the visual screening of the subject property. The total proposed disturbance
is 3.9t acres, with approximately 493 trees of six-inch diameter or greater proposed for removal.

As part of the proposed action, one new on-site wastewater treatment system (I/A OWTS) would be
installed and an existing on-site sanitary system would be replaced with an I/A OWTS. The two
systems would be designed to serve the Strong's Yacht Center operations, inclusive of all buildings,
the office and marina. Also proposed is an extension of the water main from Naugles Drive by 765
feet to allow for the site to be served by the public supply system. Upon implementation of the
proposed action, the existing on-site supply well would be available for non-potable use.
Regarding stormwater management, the proposed action includes the installation of on-site leaching
pools, French drains and the use of pervious gravel to accommodate stormwater from the proposed
development. The proposed stormwater management plan is designed to accommodate a two-inch
rain event, in accordance with Town of Southold regulations.
It is noted that in addition to the full-service marina operation, the Strong's Yacht Center currently
hosts six commercial fishing boats, and also supports the Marine Program of the Cornell Cooperative
Extension of Suffolk County, by hosting eight (8) FLUPSYs (Floating Upweller Systems), which
provide protected nurseries for hard clam seed to assist with the NYS Shellfish Restoration Initiative.
None of these activities would be affected by the proposed action.

Mallituck Town of Southold, NY
A description of each section of the DEIS is set forth below, followed by a proposed outline for the
DEIS.
Natural
Impact on Soils and Topography
This section of the DEIS will identify the existing soil type(s) on the subject property, based upon
the Suffolk County Soil Survey and any available test hole data. The grading program will also be
discussed, based upon the required plans and data (e.g., estimates of volumes of soil excavated,
cut/filled, removed from site and maximum depths of cut/fill). The topographic conditions will be
evaluated, and a topographic map will be provided. The existing and proposed changes to slopes will
be included, and stabilization measures will be identified in detail. Construction-related impacts will
also be discussed, including truck trips for soil removal and associated truck routes. Mitigation
measures for soil limitations/constraints, erosion, sedimentation, and dust generation, to the extent
necessary, will be included. See the section on Construction-related impacts for more details. The
DEIS will also:
1. Discuss the types and tested physical characteristics of the soils on site that will be subject to
excavation, future load bearing, and installation of sanitary systems and stormwater
conveyance systems. The location, size, and thickness of any clay or buried peat formations
will be described and mapped.
2. Discuss potential adverse impacts to sea grass and on shellfish from potential sedimentation.
3. Discuss possible mitigation for these potential adverse impacts.
Impact on Water Resources (Groundwater and Surface Waters)
This section of the DEIS will describe the groundwater conditions, including depth to groundwater
and groundwater quality beneath the subject property, based upon relevant documentation. The
Groundwater Management Zone IV (as classified under Article 6 of the SCSC) within which the
subject property is located, and site drainage characteristics will be described. Groundwater flow
direction based upon Suffolk County Groundwater Contour Maps and field study will be identified
and an assessment of the potential impacts to downgradient resources and nearby wells will be
included. The location of private and public wells will also be determined and a study to determine
any impacts this action might have on the quantity and quality of potable water for those wells will
be provided. This section will also include calculations of projected sanitary flow, discussion of the
proposed method of sanitary disposal (i.e., the on-site wastewater treatment systems [I/A OWTS]),
and consistency with Article 6 of the SCSC. The SCDHS Notice ot'Incomplete Application issued
for the proposed action will also be included and consultations with the SCDHS would be undertaken
as part of the DEIS and described herein. The proposed installation of four, 2,000-gallon liquid
propane aboveground tanks and consistency with Article 12 of the SCSC would be evaluated.
ZD
Groundwater quantity (i.e., water usage) will also be evaluated, including the extension of the public
water supply main to the subject property and the availability of water supply based upon
6

Strong's Yacht Center—Proposed Boat Storage Buildings
Mattiluck, Town of'Southold, NY
consultations with the SCWA. The post-development benefits of the water supply main would also
be identified. The impacts to groundwater quantity available to neighboring wells will also be
evaluated based on field studies over four seasons.
The impacts to surface waters would be evaluated, including the appropriateness of the proposed use
given the site's location and existing marina operations. Drainage and post-development stormwater
management measures, and erosion control measures, will also be discussed and evaluated in
accordance with the relevant standards. The surrounding wetlands will be described and the findings
of the NYSDEC will be included. An assessment of the Trustees standards for the issuance of a
Wetlands Permit will also be included. Finally, the effects of climate change as it relates to sea level
rise and flooding will be addressed. Mitigation measures which may reduce potential water quality
or quantity impacts will also be identified, as necessary. The DEIS will also:
1. Analyze and discuss in detail the impacts on private wells in the surrounding area including
technical details on groundwater depth, quality, quantity, freshwater lens, saltwater interface,
amount of flow in GPM, direction of travel, and travel times. Include zones of influence from
each wellhead.
2. Analyze and discuss the effect of excavation on groundwater, as well as any expected impacts
to neighboring wells. Include an analysis on the potential for salt-water intrusion into
neighboring well as a result of the excavation's effect on groundwater in the area.
3. Discuss onsite and nearby tidal wetlands and the NYSDEC's input, ecological communities
in those wetlands and their ecosystem services and values, including contributions to surface
water quality.
4. Water quality — include a discussion on the current and potential adverse moderate to large
impacts to surface water quality in the short and long term (duration). Provide the NYSDEC
shellfish closure areas,types of pollutants occurring in the creek currently, types of chemicals
in marina and vessel maintenance needs in the proposed construction and operation of the
marina facility and mitigation. Include, but not limited to, dissolved oxygen, clarity,
eutrophication, and sustainability for estuarine and marine life, as well as existing sources of
stormwater. The potential for sedimentation during construction, and resulting, post-
construction, long-term stormwater runoff contributions from the site will be described and
quantified.
5. Discuss the potential impacts to water quality from an increase in boat traffic from large boats
as a result of this action, including increased turbidity and chemical introduction through
bottom paints and other boat maintenance practices.
6. Discuss the narrowness of the creek in this area and tidal flow restrictions in an acceptable
model. Include a discussion on added restrictions to the tidal flow volume and velocity that
could result from the increase in the size and number of boats moored or docked in the creek
as a result of this action, and any additional future docks, and potential effects on water quality
from reduced tidal flushing that may result.
7. Discuss possible mitigation for these potential adverse impacts.

8. Clarifications
• Will the proposed action adversely impact any wellhead zone of influence, or the quantity
or quality of water in the aquifer that supplies nearby residential wells?
• An analysis of the groundwater on site and its contributions to the aquifer serving nearby
wells under existing conditions, and the potential adverse effects, if any, to the aquifer
serving nearby wells following excavation.
• Conduct the analysis over the course of a year to account for seasonal fluctuation in
rainfall and aquifer recharge.
• Study and describe the nature of the aquifer that supplies the nearby wells, and the
relationship of the subject property as a contributing source to that aquifer; or show that
this subject property is not a contributing source and that the proposed excavation will not
affect the quantity of water available to nearby wells.
• Direction of groundwater travel and travel times: What direction is groundwater
traveling on site? Would the excavation disrupt or interrupt groundwater travel or
timeframes to reach surface waters?
• Depth of freshwater lens and elevation of the saltwater interface: Will the proposed
excavation alter the saltwater interface in a way that may cause saltwater intrusion into
the aquifer or nearby wellhead zones of influence? Will the proposed excavation cause
upconing and saltwater intrusion by reducing the amount of fresh water entering the
aquifer used by the nearby wells. At what elevations does potable freshwater begin and
end (at the expected saltwater interface) on site pre and post excavation?
Impact on Ecologi"d Restmr-ccs
Environmental studies will be detailed and undertaken over a multi-season period (all four seasons)
to properly assess potential impacts.
This section of the DEIS would address the existing ecological resources on the subject property. As
part of the DEIS, a qualified biologist/ecologist will inspect the site to determine the vegetation,
wildlife, and general habitat character. An inventory of flora and fauna, as observed, will be prepared
and included in this section of the DEIS, and an assessment of the species that could be expected to
utilize the subject site will be performed. Protected native plants; plant and animal species listed as
endangered, threatened, and special concern (or with other protective status), will be identified,
including the noted piping plover, southern sprite, and Eastern box turtle, and suitability of habitat as
roosting or summary foraging habitat for protected New York State and Federally-protected bat
species. An assessment of potential impacts to the contiguous Town of Southold woodland identified
as 25.29 acres to the south (SCTM#1000-106-6-20.3) and the adjacent tidal wetlands of Mattituck
Creek will also be performed. Consultations with the New York Natural Heritage Program will be
undertaken for site information. This section of the DEIS will include the quantitative impacts to
habitats as well as a qualitative assessment of the impacts to plants and animal species. Mitigation
measures to reduce potential impacts will be identified. The DEIS will also:

Mattitzzck, Town ofSozahold, NY
Impact on Plants and Animals
1. Discuss potential adverse impacts to sea grass and on shellfish.
2. Provide a complete description of the ecological communities represented in the forest and
their ecological relationships to those ofthe adjoining'Town-owned preserve. Forests provide
1nlportanL ecosystem services within their bounds and for the surrounding landscape and
waterways; these ecosystem services will be described. For example, the forest ecosystem of
the subject property, contiguous with forest protected by the Town, is the last relatively large
block of native forest supplying clean groundwater to Mattituck Inlet that has not been
converted to farmland or interrupted by residential and commercial development, with their
attendant sanitary system and stormwater impacts.
3. Discuss the cumulative effect of the elimination of the forest on the subject property on the
total native forest cover in the Town of Southold.Native forest cover in the Town is relatively
rare in comparison with agricultural land and residential/commercial development;remaining
patches are isolated from one another, existing as "islands" in the overall landscape. What
patches do remain are of varying sizes, spatial relationships with wetlands and waterways,
and habitat value.
4. Include a discussion on the potential adverse impacts of net forest loss on wildlife species that
have large home ranges, including birds and bats, and that seek deep forest cover and travel
between forest patches.
5. Provide a complete analysis and discussion on the proposed destruction of the forest on the
slopes,the forest interior exposed and new forest edge, proximity to the boundary of a 25.29-
acre, Town-owned, preserve. Include the following: direct harm to the preserve by reducing
the overall size of the forest and by removing its buffer area trees that had developed in a
high-wind environment; exposure of trees that grew in an environment protected from high
wind to northeast, with attendant potential for: destabilization of root systems and tree throw;
drying of soils; increased light exposure from sunlight and night-time lighting at the storage
facility and marina (effects on plants, as well as insects and wildlife, requiring shade and
moisture); introduction of invasive species to disturbed soils; higher soil temperatures and
effects on seedling growth and forest regeneration; reduction in forest litter because of
convective drying and wind; result in reduction of nutrients available for plants and increase
in the effects of drought conditions in summer and the depth of freeze events in the winter;
increase in the ratio of forest edge to forest interior that results from decreasing the overall
size of the forest, including impacts of physical damage and biological invasions; reduction
of uninterrupted forest cover on successful nesting of warblers, thrushes, vireos and other
songbirds; reduction or loss of populations of wildlife species requiring the seclusion offered
by forest interiors and those requiring nocturnal conditions without artificial light intrusion;
degradation of habitat because of noise reaching further into the forest, both during
construction and permanently, from traffic and operations at the marina and storage site.
6. Evaluate and discuss the need to remove 493 trees and carbon sequestration and if planting of
trees elsewhere can be accomplished to offset tree loss.

7. Assess the action to Mattituck Inlet and the Significant Coastal Fish and Wildlife Habitat
(SCFWH) documentation.
8. Tidal marsh—include an assessment on the impacts from current and increase boat traffic on
low and high marsh areas within the creek. Discuss the impact from boat wakes, emissions
and chemicals (bottom paints) on the ecosystem.
9. Discuss possible mitigation for these potential adverse impacts.
Impact to the Environment
The DEIS will also:
1. Discuss the operations of the site and the overall impact on the environment.
2. Describe the short- and long-term impacts to the ecosystem,biodiversity habitats and the rarity
and significance of Mattituck Creek as an estuary, both from construction activities as well as
from operations. Discuss the impacts to the wetlands on east side of inlet and wildlife (egrets,
osprey and waterfowl).
3. The subject property's relationship to surrounding land uses and location within surface-and
groundwater contributing areas to Mattituck Creek will be described and mapped.
4. Discuss possible mitigation for these potential adverse impacts.
Impact on Flooding
1. Climate Change and Resiliency:
The DEIS will describe the potential adverse impact on the parcel resulting from climate
change and sea level rive. The DESI will:
• Discuss SEQRA's implementing regulations and measures to avoid or reduce impacts
associated with the effects of climate change such as sea level rise and flooding. See
NYCRR:617.9(b)(5)(iii)(i)]. Include the potential impacts associated with coastal flooding,
storm events, and rising sea levels. The future physical climate risk due to storm surge
(including sea level rise) and flooding should be considered in project design. The analysis
will specifically analyze the effect of rising groundwater on upland resources. The analysis
will also consider the effects of intensifying precipitation-- including more seasonal
precipitation and higher rates and more total precipitation during storms-- both during
construction and operation. The action will be assessed-to the following:
2014 C1imAID update (Horton et al. 2014) and the New York State Community
Risk and Resiliency Act (CRRA) SLR projections.
Using Natural Measures to Reduce the Risk of Flooding and Erosion Guidance
(NYDEC).

Impact on Human Health
1. Provide an analysis on the chemicals stored and disposed on site and the potential adverse
impacts from the increase in volume of chemicals used and stored on site during the proposed
action.
2. Provide NYSDEC regulations related to the storage of chemicals on site.
3. Assess potential impacts to neighboring wells (see section on Water Resources for more
details).
4. Discuss possible mitigation for these potential adverse impacts.
Impact on Transportation
The proposed action could result in a moderate to large adverse impact by significantly increasing
the number of vehicles (including construction and service vehicles) on local and regional
roadways for long durations. Capacity of the roadways may be adversely impacted. The proposed
action will add substantial traffic to the area and due to current road conditions, traffic, and
intersection conditions, the roads may not have the ability to handle it. The level of service (LOS)
at intersections may be adversely impacted.
The design and condition of the roads leading to the site (route) is a concern. Many areas exhibit
stress cracks on the pavement. The design of the roads and the ability to increase traffic on these
roads,including construction traffic and trucks, is a significant concern. Curves,declines and inclines
exist on the route to the parcel.
Receptors along the route to the parcel may be adversely impacted for long durations. The proposed
action could result in a moderate to large adverse impacts to the public and user groups from the
increase of vehicular traffic on local and regional roads affecting the public's use and enjoyment of
the roads while conducting activities (driving, walking, biking).
The number of truck trips proposed could result in large, adverse impacts to West Mill Road, Cox
Neck Road, Suffolk County Route 48, New York State Route 25, Sound Avenue, Northville
Turnpike, Suffolk County Route 58 and other local and regional roads.

Impact on Aesthetic Resources
If constructed the subject proposal may significantly alter the shoreline and community character of
Mattituck Inlet environs and this potential impact must be frilly evaluated. The proposed action is of
scale and dimension that will be visible from publicly accessible scenic resources (Mattituck Creek)
by operators of vessels using the waterway during seasonal use resulting in a potential moderate
15

Mattituck, Town of Southold NY
impact to scenic enjoyment of the waterway. Note that Mattituck Creek is a Federal waterway. The
proposed action could result in a moderate to large adverse impact to the aesthetic resource
(Mattituck Creek) through the diminishment of public enjoyment by users and members of the
community under different circumstances and activities in a location that also has an important role
in recreation and tourism economy. Both are important and changes to scenic and aesthetic resources
may have adverse impacts on both the quality of life of residents and broader economic impacts.
This section of the DEIS will describe the existing viewshed and general consistency or compatibility
with existing elements of the community. As part of the assessment of impacts on visual resources,
3D computer-generated imagery would be provided to depict post-development viewshed changes
from Mattituck Creek and the adjacent roadway. The proposed buildings and cement and evergreen
retaining wall, as well as the site and building lighting, would be described. The impacts to the
community character as it relates to changes to the existing natural landscape with the proposed
development would be evaluated. The impacts to community character as it relates to the viewshed
from waterway (Mattituck Creek) will be evaluated and the project's consistency with the proposed
use of land as set forth in approved LWRP, will be discussed. Measures to mitigate impacts will be
identified, as appropriate. The DEIS will:
1. Provide a detailed visual impact analysis for the action, including (dimensional relief and
color of site structures existing and proposed) identification of the project's zone of visual
influence (ZVI), identification of sensitive receptors (scenic views including views from
Mattituck Creeks, outdoor recreation facilities, historic properties, etc.) within that zone, and
viewshed analyses to determine if and how sensitive receptors would be affected. Computer-
generated imagery for viewshed changes should not be limited to views from Mattituck Creek
and the adjacent roadway.
2. Include detailed visual renderings of the proposed action, and alternative actions, to reflect
how the development would be viewed from the waters of Mattituck Inlet, as well as any
surrounding residential development.
3. Include a visual rendering of a typical yacht to be stored in the building as it would appear
traveling south down the creek towards the marina from the perspective of a person in a
kayak on the creek headed north.
4. Possible mitigation for adverse impacts.
Impact to Community Character
The proposed action could result in an irreversible, adverse impacts to existing community character
(physical alteration on site over a multi-year period, large building size and noise) and from the
intensity of the proposed operations near residences. Adverse impacts could occur to the community
from the construction timeframe in increased intensity and long duration. The DEIS will discuss and
analyze:
1. Flow the proposed action conforms to the town's community character priority (as stated in
the Comprehensive Plan Update), which is to "protect its scenic resources.
2. The historic and rural character of this section of Mattituck Inlet defined by in part by the
presence of the steeply sloped, thickly vegetated forest on and adjoining the site.
3. The potential permanent and irreversible adverse impacts on neighborhood character related
16

to destruction of the forest on the slopes of the subject property.
4. The potential adverse impacts of introducing big-box storage facilities on the neighborhood
character surrounding the site, the areas facing the site from across Mattituck Inlet, and the
character of the general area traversed by boaters using the inlet should be presented and
given thorough analysis.
5. The aesthetic impacts of removing native forest and hillside upon the bucolic setting of the
site.
6. The potential adverse impacts from Transportation on community character (see above).
Impact on Open Space and Recreation
The proposed action could result in a moderate to large adverse impact and significantly interfere
with nesting/breeding, foraging or overwintering habitat by removing 3.94 acres of vegetation,
including the removal of important habitat features such as dead trees used for nesting and cover.
This habitat area is connected to a 25.29 acre parcel with similar habitat that is protected by the Town
of Southold (SCTM# 106-6-20.3) to the south. This woodland assemblage comprises the largest
undeveloped acreage in the Mattituck Creek watershed. Other areas of woodland to the south and to
the west on the R-80 zoned portion of the parcel may also be affected. The DEIS will discuss and
analyze:
1. Discuss the potential adverse impacts to the Town owned preserved property, the
deforestation and impacts to the user groups of the property including hikers.
2. Analyze the adverse impacts related to noise, changes in view-sheds, the effect on wildlife,
and alteration of a sense of place from this project on the public's enjoyment of the Town
owned preserved property during all phases of the action.
3. Discuss the impacts of the increased large vessel traffic in the inlet, and its effects on small
local vessels, kayaks, and paddle boarders attempting to navigate the narrow creek.
4. Potential mitigation for adverse impacts.
Impact from Noise
The proposed action could result in a moderate to large adverse impact from excessive noise levels
during multiple phases over long duration. Noise associated with the operation of heavy equipment
and trucks includes but is not limited to; engine noise, noise from moving and backing up heavy
equipment (reversal warning sound) and the operation, accelerating and deceleration and Jake
braking of trucks on site and on roadways. Similarly, operation of chain-saws and wood chippers for
long durations may generate large, adverse noise impacts to receptors in the neighborhood. The
DEIS will HICILide, discuss and analyze the following:
I. A comprehensive noise study. Include M the assessment existing ambient noise levels, noise
produced by all phases of the project, the sources of the noise, and including hours, duration,
decibel level both at the source and at the receptor sites (e.g., the outdoor spaces of
neighbors' properties such as decks or back yards), and impact on tranquility for residents
within hearing range, as well as wildlife. Discuss the duration of each type of noise expected.
Include an evaluation of cumulative noise generation where multiple machines/activities
17

might be running simultaneously. Include protocols for monitoring of the noise level during
construction and during operations and include how noise will be attenuated or mitigated.
2. Analyze and discuss the potential significant adverse impacts from noise on the quality of
life and to public health resulting from all phases of site work and construction over long
durations over a multi-month period.
3. Include the potential adverse impacts from noise on receptors and wildlife generated by the
operation of machinery, heavy equipment and trucks both on-site and off-site as they travel
through neighborhoods and the region including:
➢ Noise from the operation of machines, heavy equipment and truck engines
moving and backing up(reversal warning sound),accelerating and deceleration.
➢ Noise from Jake braking of trucks on roadways.
➢ Noise from the operation of chain-saws and wood chippers for long periods and
potential large, adverse impacts to receptors in the neighborhood and wildlife.
➢ Noise generated by each alternative.
4. Clarify whether or not blasting will be conducted,
5. Discuss the adverse impacts on the quality of life from the noise generated from the action
and what mitigation is proposed to lessen adverse impacts.
Impact on Air Quality
The proposal involves the operation of heavy machinery and trucks on and off site over a long
duration of time that could result in moderate adverse impacts to local air quality.
This section of the document will address mobile source impacts (i.e., those related to construction
activity)and post-development impacts to biomass as a result of the proposed land clearing activities.
An air quality assessment will be performed and appended to the DEIS and summarized in the body
of the text. The air quality assessment would include the following:
➢ Mobile Sources - The latest version of the Motor Vehicle Emission Simulator
(MOVES2014b), developed by the USEPA Office of Transportation and Air Quality,will be
used to estimate emissions associated with off-road and on-road mobile engines. If available,
emission factors will be obtained from the NYSDEC or NYSDOT MOVES specific data for
the County of Suffolk, otherwise national average emission factors in MOVES for Suffolk
County using default distribution assumptions will be used. Mitigation measures, as required,
will also be identified.
N'lb,
1'.__._oLi le F'q-ij-i'r'ac"itit - Activity levels (i.e. hours of operation) of each piece of
equipment will be estimated based on the square footage of the construction area and the
associated activity type. The activity levels represent the total number of hours each piece
of equipment is anticipated to be used for the duration of the project. Operating hours
will be based on the projects need for the equipment rather than assuming continuous

operation. It is assumed that all off-road equipment will operate on diesel fuel. Off-road
mobile equipment emission rates for criteria pollutants will be computed and compared
with USEPA National Ambient Air Quality Standards (NAAQS). Emission rates for
hazardous air pollutants (HAPs) will be computed and compared to New York State
Department of Environmental Conservation DAR-1 Guidelines for the Evaluation and
Control of Ambient Air Contaminants Under Part 212.
➢
On-Roa,d Mobile Vehicles - Vehicle miles traveled (VMT) data for each on-road
construction vehicle and employee trips will be estimated from roundtrip distances and
the number of vehicles and employees based on the activity specific construction
schedule. It is assumed that all on-road equipment will use either gasoline or diesel fuel.
Typical vehicle types will be passenger car, passenger truck, single unit short-haul, and
commercial short-haul. The emission rates for criteria pollutants on-road construction
vehicles will be computed and compared to USEPA National Ambient Air Quality
Standards (NAAQS). Emission rates for hazardous air pollutants (HAPs) will be
computed and compared to New York State Department of Environmental Conservation
DAR-1 Guidelines for the Evaluation and Control of Ambient Air Contaminants Under
Part 212.
➢ Fui(ive Dust - Fugitive dust emissions (particulate matter or PM) from site preparation,
land clearing, equipment movement on unpaved areas, material handling will be
calculated utilizing USEPA published emission factors (USEPA, Air Emission Factors
and Quantification, AP-42: Compilation of Air Pollutant Emission Factors). Erosion
control measures and water programs to minimize fugitive dust and particulate emissions
at construction sites will be considered in the analysis. Estimated emission rates for
particulate matter (PM) will be computed and compared to USEPA National Ambient
Air Quality Standards (NAAQS) for PM2.5 and PM 10.
➢ Carbon Seq'i,teste'i"J'iwo — The proposal also involves the removal 3.94 acres of soil and
vegetation including 493+ hardwood trees contributing to carbon sequestering. Carbon
sequestration is the process by which atmospheric carbon dioxide is taken up by trees,
grasses, and other plants through photosynthesis and stored as carbon in biomass (trunks,
branches, foliage, and roots) and soils. The oak is the genus with the most carbon-
absorbing capabilities, there are other notable deciduous trees that sequester carbon as
well.
Carbon sequestering estimates will be determined utilizing published sources, including
but not limited to: USEPA, Office of Atmospheric Programs, Greenhouse Gas Mitigation
in U.S. Forestry and Agriculture carbon sequestering factors; U.S.Department of Energy,
Energy Information Administration, Method for Calculating Carbon Sequestration by
Trees in Urban and Suburban Settings; and/or 2006 Intergovernmental Panel on Climate
Change (IPCC) Guidelines for National Greenhouse Gas Inventories. Sources will be
dependent on the most up to date and appropriate specific to the types of vegetation/soil
conditions and the classification of the area to be cleared. Soil types will be identified
from soil boring logs and published data through the USDA Suffolk County Soil Survey.

Construction-Related Impacts
This section will address the construction-related impacts related to vegetation and material removal,
site preparation, and construction activities. The proposed excavation plan will be presented, and the
impacts associated with noise, traffic and land disturbance activities (e.g., dust) will be assessed.
Measures to mitigate impacts will be identified, as appropriate. The DEIS will:
1. Identify specific materials e.g., excavated materials, vegetation, concrete and building
materials.
2. Discuss the potential adverse impacts from water line and natural gas extensions on public
roads.
3. Discuss why the project is necessary as proposed.
4. Discuss why this parcel is suitable for this project. This project will require large amount of
forest, slope and soil removal.
5. Discuss why the construction of the buildings requires the need to excavate 134,921CY of
soil and why the buildings cannot be constructed without excavation.
6. Clarify if the cubic yard calculation of soil to be excavated from the site includes a "swell"
factor.
7. Discuss why the length of construction is necessary (13 months).
8. Discuss how the R-80 zoned portion of the parcel will be affected by the proposed action,
9. Provide a complete evaluation of impacts associated with all proposed mining, erosion, materials
transport (including roadway impacts and impacts on nearby residential development), materials
storage, materials sales, materials processing, vehicle operations, and habitat destruction. The
proposed action requires an extensive amount of excavation,Which Will ultimately result in significant
off-site transport of sands and gravels extracted from the site. Please provide official
documentation in the DEIS that no action on-site constitutes mining.
10. Assess the noise from all stages of site preparation and construction as described in more
detail in the Noise section above.
11. Describe in detail the process by which the temporary road will be constructed and the
impacts that will result including but not limited to noise, vibration, vegetation and soil
removal, and tree removal.
12. Discuss the potential of slope failure and effect of excavation and ground vibration from the
operation of machinery, heavy equipment and trucks on existing neighboring structures.
20

Strong's Yacht Center—Proposed Boat Storage Buildings
Matliluck, Town of Southold, NY
13. Discuss the potential of destabilization of adjacent properties and impacts from vibration and
excavation on adjacent properties, the impact of timing in between each phase, the threat of
catastrophic soil loss and erosion if there is a pause in the project schedule due to weather or
other event, and the future maintenance, type of construction, inspection schedules and
monitoring for defects of the retaining wall. The potential catastrophic failure of the retaining
wall, in whole or in part and effect on adjacent properties.
14. Address growth inducing actions and if there will be a future request to develop the property
and/or increase the size of the marina/docks as a result of this proposed project. And if the
marina and docks will be expanded as a result of this proposed project, discuss whether or
not that would constitute the segmentation of the SEQRA review if that expansion is not
included in this review.
15. Discuss the potential need to increase the boat storage capacity of the current site and for a
future travel lift, boat staging, in water docking and the impact on adjacent wetlands.
16. Discuss if the excavated material can be removed by barge through Mattituck Inlet for off-
site disposal.
17. Discuss how the unexpected site conditions,weather,pandemic, and work flow and schedule
changes will be addressed to not impact the community?
18. Provide a complete evaluation of impacts associated with all proposed mining, erosion,
materials transport (including roadway impacts and impacts on nearby residential
development), materials storage, materials sales, materials processing, vehicle operations,
and habitat destruction.
19. Discuss alternative plans for disposal of any excavated material that cannot be sold, and
provide an evaluation of any disposal sites, other than commercially-operated sites
specifically designed to receive fill. Identify the off-site disposal location.
20. Include a plan for specifically targeted and carefully undertaken soil borings to inform an
excavation plan that is designed to prevent catastrophic mass soil movement and soil
slumping. The DEIS will not rely solely on published soil surveys or soil borings performed
by others for a project involving excavation of I34,000CY of a forested hill's soil, especially
one adjoining a waterway. Without specifically targeted and carefully undertaken soil
borings to inform an excavation plan, the potential exists for a catastrophic mass soil
movement event during, or subsequent to, disturbance of the steep slopes by heavy
equipment. The proposed excavation could cause sudden faulting and structural disturbances
associated with the slope and soil slumping to the immediately adjoining and steeply sloped
preserve, as well as cause sedimentation in the waterway. Sedimentation can have a
devastating effect on the estuarine life in the inlet because of rapid burial and destruction of
benthic organisms, such as shellfish or Crustacea.
21. Discuss the effect of precipitation on the re-established steep slope with regard to potential
exacerbation of soil movement. It also will show the new retaining structure can adequately

support the final slope and resulting hydrostatic pressure behind the wall.
22. Mitigation of potential adverse impacts.
Consistency with Community Plans and Studies
In 2020, the Town adopted The Southold Comprehensive Plan, the proposed project will be assessed
to the goals and objectives of this plan and others. The DEIS will:
1. Include a section focused on the consistency between the proposed action (and alternative
actions), and the relevant goals, objectives, and standards of existing planning, land use and
policy documents relevant to the subject site and its surroundings.
2. An in-depth analysis of the action on the following policy and planning documents,
legislation, and implementing rules and regulations:
o Southold Town Comprehensive Plan
al Natural Resources and Environment
Community Character
Land Use and Zoning (Marine Zoning Update)
Natural Hazards
Economic Development
Transportation and Infrastructure
o Town of Southold Local Waterfront Revitalization Plan & Policies
o State and local wetlands protection laws
o The Mattituck Watershed Management Plan
o "NYSDEC Environmental Resource Mapper" -with respect to wildlife evaluation
o NYSDOS Coastal Significant Fish and Wildlife Habitat designations (Mattituck Inlet)
o Articles 6,7 and 12 of the Suffolk County Sanitary Code
Impacts on Archeological and Cultural Resources
The parcel is located within an area with historic use and buildings. The DEIS will discuss the
following potential, adverse impacts to archeological and cultural resources from the action. The
DEIS will:
1. Discuss the project's potential impacts to historic and archeological resources.
a. Part 11 of the Full EAF for the project indicates that the project is not adjacent to a historic
or archeological site. However, NYSDEC guidance on how to prepare the EAF notes that
in preparing responses in this section of the EAF one must ask "Does the project site
I with, a known archaeological site, I
contain, or is it contiguous w even though it may not be
72
Final Scope for Final Environmental Impact,51atement

Maltituck, Town of'Soulhold, NY
included on the NY SHPO inventory?" As no archeological survey of the project area has
been made it is not possible to answer this question in the negative.
b. Although NYS OPRHP's Cultural Resources Information System (CRIS) does not identify
the project area as archeologically sensitive, this should not be construed as meaning that
the area does not have the potential to contain potentially significant archeological
resources. CRIS relies on the prior identification of archeological sites in proximity to a
given area to evaluate sensitivity. CRIS's archeologically sensitive GIS layer specifically
states: "Note that locations outside of the buffer areas may also be archaeologically
sensitive." In the case of the project area the failure to identify it as "sensitive" is a reflection
of the total lack of prior archeological surveys in the immediate vicinity of the project. The
project area's location on high ground adjacent to Mattituck Creek (believed to be part of a
principal portage route used by Native Americans to travel from the North to South shores
of Long Island), suggests that evidence of Native American occupation could be present.
c. There are three unevaluated structures listed in CRIS within approximately 1000 feet of the
project area. Include an evaluation as to if and how these structures may be visually or
otherwise (noise, vibration during construction) affected by the project and, if potentially
affected, if they satisfy the eligibility criteria for the State Register of Historic Places.

Initial Identification of Mitigation N'legasures
As the DEIS analyses have not yet been conducted, no specific mitigation measures have yet been
developed. Nonetheless, where the impact analyses conducted in the DEIS indicate the potential for
significant adverse impacts, the DEIS will set forth measures to mitigate those impacts within the
topic sections, as presented herein.
Reasonable Alternatives to Be Considered
Pursuant to 6 NYCRR Part 617, the DEIS must contain a description and evaluation of reasonable
alternatives to the proposed action that are feasible, considering the objectives and capabilities of the
project sponsor. This DEIS will analyze the impacts of the following alternatives and compare
(quantitatively and qualitatively) these impacts to those associated with implementation of the
proposed action, based upon the specific issues outlined above:
1. No-Action (site remains as it currently exists).
2. Alternative Material Removal Plan — This alternative is intended to mitigate the impacts
associated with the removal of material via trucks over local roadways and will include the
barging of cleared vegetation including trees, stumps and excavated materials.
3. Constructing the project on another site.
4. tl
Constructing g the proposed storage buildings without the need for excavation.
5. Constructing smaller building(s) with less excavation.
6. The reconfiguration or reconstruction of existing buildings on-site for larger boat storage.
l"I"ODOsed Or,x1111iZatiOfl and Overall Content of the DEIS
The DEIS will conform with the basic content requirements as contained in 6 NYCRR Part 617.9
