1. Existing Conditions
a. Introduction
Ecological surveys were conducted at the 32.96 acre Strongs Marine property by Dr. William
Bowman of Land Use Ecological Services. Survey dates included September 18, 2020; October
21, 2020; January 17, 2021; May 13, 2021; July 19-28; 2021; and August 24, 2021. Ecological
investigations including a tree survey with species identification for all trees greater than 6 inches
diameter. Plant and wildlife lists for the site are provided in Tables 2-5. A total of 105 vascular
plant species were observed, including 49 woody plants, 53 herbaceous plants, and three ferns
(Table 2). Additionally, 84 birds, 20 mammals and three herpetiles were observed or are
expected to occur on the site.
b. Ecological Communities
Between the mid-1950s and 1984, the site consisted of agricultural fields adjacent to Mill Road,
a small tree plantation or orchard, forests, and a marina facility, as indicated by aerial imagery
from Suffolk County (www.suffolkcountyny.gov/Portals/0/planning/Cartography/1930/
sc19304f2WEB.pdf). During this time, cleared land associated with the agricultural and
commercial marine uses accounted for approximately 58% (19.1 acres) of the 32.96 acre
property. Aerial imagery of the site from 1962 and 1984 is provided in Figures 1 and 2. The
agricultural use on the western portion of the site appears to have been abandoned in the late
1980s. The existing ecological communities now present at the site include coastal oak-beech
forests; successional habitats that have developed on the former agricultural lands including
southern successional hardwood forests and successional shrublands; a small tidal wetland area
associated with Mattituck Creek; and anthropogenic cover types such as mowed lawn with trees,
buildings, and paved and pervious road and parking surfaces. The existing boundaries of the site’s
ecological communities are shown in Figure 3 and the acreage of each ecological community
type and the percentage of the total site area are provided in Table 1. Descriptions of the
ecological communities observed are provided along with the New York Natural Heritage
Program community descriptions from Edinger et al (2014).

Coastal Oak-Beech Forests
Coastal oak-beech forests represent 12.60 acres, or 38.2% of the site, from the steep, east-facing
slope adjacent to the existing marina extending west on the site’s hilltops and slopes. The
following is the definition of this community as described by Edinger et al (2014):
“A hardwood forest with oaks (Quercus spp.) and American beech (Fagus grandifolia)
codominant that occurs in dry, well drained, loamy sand of morainal coves of the coastal
plain. Some occurrences are associated with maritime beech forest. American beech can
range from nearly pure stands to as little as about 25% cover. The forest is usually
codominated by two or more species of oaks, usually black oak (Quercus velutina) and
white oak (Q. alba). Scarlet oak (Q. coccinea) and chestnut oak (Q. montana) are common
associates. Red oak (Q. rubra) may be present at low density, and is a key indicator species
along with sugar maple (Acer saccharum) and paper birch (Betula papyrifera). There are
relatively few shrubs and herbs. Characteristic ground layer species are Swan's sedge
(Carex swanii), Canada mayflower (Maianthemum canadense), white wood aster (Eurybia
divaricata), beech-drops (Epifagus virginiana), and false Solomon's seal (Maianthemum
racemosum). Typically, there is also an abundance of tree seedlings, especially of American
beech; beech and oak saplings are often the most abundant “shrubs” and small trees.”
The high-quality coastal oak-beech forests on the site consist of abundant large trees (ranging
between 6 and 39 inches in diameter). American beech (Fagus grandifolia) accounts for
approximately 33% of the tree stems with the remainder of the canopy consisting of relatively
equal proportions of black oak (Quercus velutina), white oak (Q. alba), scarlet oak (Q. coccinea),
and chestnut oak (Q. montana). Red maple (Acer rubrum) and pignut hickory (Carya glabra) are
also present as canopy trees. Tree species that are dominant in the understory are American
beech and red maple, and, to a lesser extent, the various oak species. The shrub- and ground
layers of vegetation are sparse due to the dense shade under the beech-dominated canopy and
heavy browsing from white-tailed deer.
Coastal oak-beech forests in New York State are typically found on the north-facing slopes of
glacial moraines of Suffolk and Richmond Counties. Numerous examples occur along the North
Shore of Suffolk County from Wildwood State Park to Route 48 in Southold; from Big Woods
(Southampton) to Montauk Point on the South Fork (NYNHP, 2020); the headland necks of
Suffolk County that extend into Long Island Sound, such as Lloyd Neck (Greller, 1977); and small

patches farther west on Long Island into Nassau County and eastern Queens counties (Greller,
1977).
Edinger et al (2014) indicates that this ecological community is restricted to Suffolk and Richmond
Counties in New York State with a rarity ranking of G4 and S3 indicating that this community
type is considered “apparently secure” globally and “vulnerable” in New York State, i.e. vulnerable
to disappearing from New York (but not currently imperiled) due to rarity or other factors.
Successional Southern Hardwoods
Successional southern hardwoods represent 4.67 acres, or 14.2% of the site. The following is
the definition of this community as described by Edinger et al (2002):
“Hardwood or mixed forest that occurs on sites that have been cleared or
otherwise disturbed. “Characteristic trees and shrubs include any of the following:
American elm (Ulmus americana), slippery elm (U. rubra), white ash (Fraxinus
americana), red maple (Acer rubrum), box elder (Acer negundo), silver maple (A.
saccharinum), sassafras (Sassafras albidum), gray birch (Betula populifolia), hawthorns
(Crataegus spp.), eastern red cedar (Juniperus virginiana), and choke-cherry (Prunus
virginiana). Certain introduced species are commonly found in successional forests,
including black locust (Robinia pseudo-acacia), tree of heaven (Ailanthus altissima),
and buckthorn (Rhamnus cathartica). Any of these may be dominant or codominant
in a successional southern hardwood forest. Southern indicators include American
elm, white ash, red maple, box elder, choke-cherry, and sassafras. This is a broadly
defined community and several seral and regional variants are known.”
At the site, this ecological community is dominated by early successional tree species including
black cherry (Prunus serotina), black locust (Robinia pseudoacacia), eastern red cedar (Juniperus
virginiana), Norway maple (Acer platanoides), and bird cherry (Prunus avium) that have re-grown
on formerly cleared areas or former agricultural fields. The understory and ground layers in the
site’s successional forests consist of dense thickets of multiflora rose (Rosa multiflora), various
brambles (Rubus phoenicolasius and Rubus alleghanensis), catbriar (Smilax rotundifolia), Asiatic
bittersweet (Celastrus orbiculatus), Japanese honeysuckle (Lonicera japonica), and poison ivy
(Toxicodendron radicans).

Edinger et al (2014) indicates that this ecological community is distributed throughout New York
State with a rarity ranking of G5 and S5 indicating that these communities are considered
“demonstrably secure” both in globally and in New York State.
Successional Shrublands
Vegetation typical of successional shrublands represents 10.83 acres, or 32.9% of the subject
property on the former agricultural lands on the western portion of the property. The following
is the definition of this community as described by Edinger et al (2014):
“A shrubland that occurs on sites that have been cleared (for farming, logging,
development, etc.) or otherwise disturbed. This community has at least 50% cover
of shrubs. Characteristic shrubs include gray dogwood (Cornus racemosa), eastern
red cedar (Juniperus virginiana), raspberries (Rubus spp.), serviceberries
(Amelanchier spp.), choke-cherry (Prunus virginiana), wild plum (Prunus americana),
sumac (Rhus glabra, R. typhina), nanny-berry (Viburnum lentago), and arrowwood
(Viburnum dentatum var. lucidum). Non-native invasive shrubs include hawthornes
(Crataegus spp.), multiflora rose (Rosa multiflora), Russian and autumn olive
(Elaeagnus angustifolia, E. umbellata), buckthorns (Rhamnus cathartica, Frangula
alnus), and shrubby honeysuckles (Lonicera tatarica, L. morrowii, L. maacckii).”
The successional shrublands at the site are dominated by autumn olive (Elaeagnus umbellata) with
thickets of brambles (Rubus phoenicolasius, Rubus allegheniensis, and Rubus flagellaris) and multiflora
rose (Rosa multiflora). Native and old field grasses and wildflowers including goldenrods
(specifically Solidago rugosa, Solidago canadensis, and Euthamia gramnifolia), pearly everlasting
(Anaphalis margaritacea), and intermediate dogbane (Apocynum cannabinum) are present along the
maintained margins of trails and paths. Invasive fountain grass (Miscanthus sp.) was also common.
The site’s successional shrublands contain many small stands of successional trees, mostly black
cherry (Prunus serotina) and eastern red cedar (Juniperus virginiana), with infestations of Asiatic
bittersweet (Celastrus orbiculatus). Edinger et al (2014) indicates that this ecological community
is distributed throughout New York State with a rarity ranking of G4 and S4 indicating that these
communities are considered “apparently secure” both in globally and in New York State.
Tidal Wetlands

The site’s tidal wetlands are located along Mattituck Creek in an un-bulkheaded section
of shoreline at the southern end of the property. These tidal wetlands occupy
approximately 0.63 acres or 1.9% of the property. The tidal wetlands consist mostly of
Spartina alterniflora-dominated intertidal marsh. The landward margin of the tidal wetlands
is dominated by invasive common reed (Phragmites australis) with scattered groundsel
bush (Baccharis halimifolia) and marsh elder (Iva frutescens). There is a narrow band of
high marsh vegetation between the Phragmites and intertidal marsh, including salt hay
(Spartina patens), spike grass (Distichis spicata), and seaside lavender (Limonium
carolinianum).
Tidal Wetlands in Mattituck Creek
Approximately 60-acres of tidal wetlands and 10-acres of unvegetated shoals and mudflats
are located within Mattituck Creek; mostly on the east side of Mattituck Creek to the
north of Mill Road, and including the New York State Mattituck Creek Tidal Wetlands
Preserve. In 2005, the tidal wetlands in Mattituck Creek were comprised largely (more
than 90%) of native intertidal and high marsh communities with relatively low abundance
of invasive Phragmites-dominated marshes (NEIWPCC, 2015). No submerged aquatic
vegetation beds, e.g. eelgrass (Zostera marina), are known to occur in Mattituck Creek
(Long Island Sound Study, 2017).
The tidal wetlands and beaches of Mattituck Inlet are designated as a Significant Coastal
Fish and Wildlife Habitat by the New York State Department of State (NYSDOS, 2005).
Mattituck Creek is designated as a Significant Coastal Fish and Wildlife Habitat, in part, as it
is one of few or rare undeveloped tidal wetlands in eastern Suffolk County with a
deepwater inlet and strong tidal flushing tributary to Long Island Sound (NYSDOS, 2005).
Ecosystem functions and values provided by the tidal wetlands of Mattituck Creek include
supporting fish and shellfish populations and a productive recreational fishery, uptake or
trapping of land-derived nutrients and contaminants, providing wildlife habitat, protecting
upland and shoreline areas from flooding and erosion, and providing water-based
recreational opportunities.
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022

The wetlands of Mattituck Inlet provide foraging and breeding habitat for a wide variety
of fish and wildlife species including wading birds (such as great egret, snowy egret, and
green heron), least and common tern, osprey, and waterfowl (such as American black
duck, gadwall, and mallard). Federal- and New York State-protected shorebirds, such as
piping plover and least tern, nest on the nearby beaches adjacent to Mattituck Inlet and
forage in appropriate tidal wetlands, shoals and mudflats, and estuarine waters of
Mattituck Creek. Mattituck Creek supports populations of marine and estuarine fish
including bluefish, striped bass, weakfish, fluke, black sea bass, winter flounder, striped and
northern sea robins, blackfish, oyster toadfish, and scup.
Shellfish that inhabit the waters in and adjacent to Mattituck Creek include surf clams,
hard clams, oysters, and blue mussels. The northern reaches of Mattituck Creek are
certified by the NYSDEC for the harvest of shellfish during the months January through
April. The headwaters of Mattituck Creek (upstream of Point Pleasant) and the Howards
Creek and Long Creek tributaries are not certified for shellfish harvest. The NYSDEC
Mattituck Inlet/Creek is assessed as an impaired waterbody due to pathogen pollution
from urban and storm runoff (NYSDEC, 2016).
c. Plants
A plant list for the 32.96-acre Strong’s Marine property (Table 2) was prepared based on
ecological surveys completed by Dr. William P. Bowman in 2020 and 2021. A total of 105
vascular plant species were observed at the site, including 53 woody plants, 62 herbaceous plants,
and three ferns.

Ecological investigations included a tree survey for all trees greater than 6 inches diameter with
2,408 trees identified on the 32.96-acre property (1,054 on the R-80 portion of the property and
1,354 on the M2 portion of the property). Twenty-six tree species were recorded. Dominant
tree species present were various oaks including black oak (10.8%), scarlet oak (7.6%), white oak

(5.8%), and chestnut oak (3.4%); American beech (19.2%); red maple (11.3%); black locust (11.0%);
black cherry (8.3%), eastern red cedar (6.2%), and sassafras (5.8%). The mean diameter of the
sampled trees was 11.9-inches. Large trees are abundant on the property with trees greater than
18-inches in diameter accounting for 12.7% of sampled trees.
d. Wildlife
The birds, mammals, and herpetiles observed or expected to occur on the subject property
(presented in Tables 3-5) are based on field surveys by Dr. William P. Bowman in 2020 and
2021. The range of ecological communities present on the site provides habitats for wildlife
species inhabiting both early successional habitats and mature forest patches.
Birds
Approximately 84 bird species were observed or are expected to occur on the site (Table 3).
Approximately 60% of these birds (i.e. 50 species) may utilize the property for breeding habitat
based on the observed habitat conditions and known bird breeding activity documented in the
2008 New York Breeding Atlas in the vicinity of Mattituck (McGowan and Corwin, 2008).
Approximately 38% of these birds (i.e. 32 species) are expected to transiently utilize the site
seasonally, such during the summer months only, only during spring and autumn migrations, or
as overwintering habitat. The remaining species (52 species) can be found year round in
appropriate habitats on Long Island.
The mature coastal oak-beech forests provide high-quality habitat that may be utilized by a variety
of songbirds including American redstart (Setophaga ruticilla), wood thrush (Hylocichla mustelina),
great crested flycatcher (Myiarchus crinitus), black-and-white warbler (Mniotitla varia), ovenbird
(Seiurus aurocapilla), and northern parula (Parula americana). Due to the proximity to existing
forest edges along former agricultural lands, residential properties, and the commercial marina,
the site’s forests are also utilized by common suburban birds. These species include American
robin (Turdus migratorius), house wren (Troglodytes aedon), common flicker (Colaptes auratus),
tufted titmouse (Baeolophus bicolor), blue jay (Cynaocitta cristata), and cardinal (Cardinalis cardinalis).
Dead trees, snags, and limbs in these forests provide habitat for cavity-nesting birds and
woodpeckers including red-bellied woodpecker (Melanerpes carolinus) and downy woodpecker
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022

(Picoides pubescens). In addition, the dense thickets of shrubs and small trees on the former
agricultural lands provide excellent habitat for songbirds which prefer dense vegetation including
song sparrow (Melospiza melodia), American goldfinch (Spinus tristis), yellow warbler (Dendroica
petechia), ruby-crowned kinglet (Regulus calendula), common yellowthroat (Geothlypis triches), gray
catbird (Dumetella carolinensis), northern mockingbird (Mimus polyglotta), and yellow-rumped
warbler (Dendroica coronata).

Mammals
Mammal species (or scat/sign of these species) observed at the site include gray squirrel (Sciurus
carolinensis), eastern chipmunk (Tamias striatus), meadow vole (Microtus pennsylvanicus), white-
footed mouse (Peromyscus leucopus), raccoon (Procryon lotor), and white-tailed deer (Odocoileus
virginianus). Table 4 provides a list of all mammal species observed or expected to occur on site
based on habitat preferences (Connor, 1971) and the ecological communities present. All
observed or expected mammals are common in suburban landscapes; prefer open, early
successional habitats; and/or are tolerant of human activity.
Bat species that utilize forested habitats on Eastern Long Island include big brown bat (Eptesicus
fuscus), eastern red bat (Lasiurus borealis), and northern long-eared bat (Myotis septentrionalis)
(Fishman, 2013; Connor, 1971). Big brown bat and red bat are habitat generalists typically
foraging in forest edges, open habitats, and over wetlands and surface waters. Northern long-
eared bats utilize a wide variety of upland woodland and forest types (NYNHP, 2016), but are
typically associated with mature interior forest (Carroll et al, 2002) and tend to avoid woodlands
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022

with significant edge habitat (Yates and Muzika, 2006). Other studies have found that northern
long-eared bat can also be found using younger forest types (NYNHP, 2016). Recent bat
monitoring conducted by the NYSDEC has suggested that northern long-eared bats on eastern
Long Island are not sensitive to forest patch size and may utilize forest patch as small as one acre
(Hoff, 2019). The northern long-eared bat (Myotis septentroinalis) was listed in 2016 as threatened
by the US Fish and Wildlife Service and the New York State Department of Environmental
Conservation.
The project site may provide habitat for these bat species during the summer months and
migration periods in the spring and autumn. There is growing evidence that northern long-eared
bat also overwinter on eastern Long Island, hibernating in human structures and foraging for
winter-flying moths when temperatures exceed 4°C (Hoff, 2019). During the summer months,
bats are expected to forage within the site’s forest, forest edge, and successional shrubland
habitats and over the wetlands and surface waters of Mattituck Creek. Tree cavities and crevices
serve as day roots for these species, with human structures also used by big brown bat.

Reptiles and Amphibians
Few species of reptiles and amphibians are expected to occur on the subject site due to the
absence of freshwater habitats. The species that are expected to be present based on site
observations, existing habitat types, and the New York State Herpetological Atlas (NYSDEC,
2009) are listed in Table 5. The New York State Herpetological Atlas provides known records
of reptile and amphibian species from 1990-1998 for each 7.5-minute USGS topographic
quadrangle within New York State. The expected reptile and amphibian species listed in Table
5 are based on the Southold, NY quadrangle. The eastern box turtle (Terrapene carolina) is listed
as a New York State Species of Special Concern and is a common inhabitant of dry and moist
woodlands, brushy fields, marsh edges, and bottomlands (Massachusetts Division of Fisheries and
Wildlife, 2015). Redback salamander can be found in woodlands throughout New York State.
The common and ubiquitous garter snake can be found in various woodlands, fields, and suburban
habitats.

b. Endangered, Threatened, Rare Species or Significant Ecological
Communities

correspondence from December 1, 2020 indicates that piping plover (Charadrius melodus), a New
York State threatened species, is the only record of a known occurrence of a rare or state-listed
animal or plant or significant natural community on or in the vicinity of the site (Appendix A).
Piping plovers nest at Breakwater Beach located more than 0.5 miles away on the west side of
Mattituck Inlet. No breeding or foraging habitat for piping plover is present on the site.
The NYSDEC EAF Mapper (https://gisservices.dec.ny.gov/eafmapper/) indicated the potential for
southern sprite (Nehalennia integrecollis), a damselfly listed as a Species of Special Concern in New
York State, to occur in the vicinity of the project site. Southern sprite are found in coastal plain
ponds on Long Island (NYNHP, 2010). Due to the absence of suitable habitat, southern spite are
not expected to occur on the subject property.
As described above, the site contains habitat that could be utilized by the northern long-eared
bat (Myotis septentrionalis) during the summer months for foraging and diurnal roosting. The
northern long-eared bat was listed as threatened by both the US Fish and Wildlife Service and
New York State in 2016 due to population declines caused by white-nose syndrome (WNS), a
disease caused by an invasive fungus that kills affected hibernating bats during the winter months.
Northern long-eared bats roost during the daytime in cavities or crevices of living trees and snags
(i.e. standing dead trees) or underneath loose or exfoliating bark. The site has large trees with
loose bark, such as red maple and white oak, and potential for cavities in live trees or snags. Due
to the northern long-eared bat’s potential use of diverse upland forest types and the presence of
large trees with loose bark, this species may utilize the site for foraging and roosting habitat in
the summer months.
The availability of summer habitat is not limiting for northern long-eared bat. Accordingly, loss
of summer habitat is not recognized as a threat to the conservation of this species (USFWS,
2016); rather, white-nose syndrome is the primary threat to northern long-eared bat within its
summer habitats.
Three species listed as Species of Special Concern by New York State are expected to occur
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022

on or utilize the site. Species of Special Concern are species for which a welfare concern or
risk of endangerment has been documented in New York State. These three species include:
Eastern Box Turtle Terrapene carolina
Cooper’s Hawk Accipiter cooperii
Sharp-shinned Hawk Accipiter striatus
Eastern box turtle (Terrapene carolina) may be found in a wide variety of habitats including in open
deciduous forests, woodlands, forested bottomlands, open field and field edges, thickets, marshes,
bogs, and stream banks. Eastern box turtle are expected to be found in any of the vegetated
upland habitats on the site. Eastern box turtles are threatened by development of their habitat,
mortality on roadways, mortality from mowing of lawns and early successional habitats, and
collection as pets.
Cooper’s hawk (Accipiter cooperii) and sharp-shinned hawk (Accipiter striatus) inhabit various upland
and wetland forests during the breeding season including fragmented forests within agricultural,
suburban, and urban landscapes, with sharp-shinned hawks preferring forest edge habits.
Cooper’s hawks breeding sites have been expanding in New York over the last several decades.
Cooper’s hawks prefer to nest in forests with a closed canopy, trees that are more than 30 years
old, and moderate to heavy shrub cover (Beans and Niles, 2003). The site’s coastal oak-beech
forests provide suitable, but not optimal, nesting habitat due to the relative absence of shrub
cover. Sharp-shinned hawks were not documented to nest anywhere in Nassau or Suffolk
Counties by McGowan and Corwin (2008). During the winter months, both species frequent
residential areas to hunt for songbirds at bird feeders. Both species are expected to utilize the
subject site as foraging habitat during any season.
2. Potential Impacts Analysis
The proposed action is the construction of two boat storage buildings (52,500 square feet and
49,000 square feet, respectively) along with associated improvements including a vegetated
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
20
retaining wall, gravel-based driveway and parking surfaces, water supply, sewage disposal using
new Innovative/Alternative Onsite Wastewater Treatment Systems (I/A OWTS), site grading and
drainage, landscaping and lighting on the 32.96 acre parcel on lands zoned M-11 (16.46 acres) and
R-80 (16.5 acres). The proposed action will require approximately 135,000 cubic yards of cut
for the placement of the proposed boat storage buildings at El. 10.0’ NAVD. A concrete and
planted retaining wall is proposed to the west and north of the new boat storage buildings to
stabilize the slope. Construction is anticipated to occur over a 12-month period including
excavation and fill export and construction of proposed retaining wall, boat storage buildings, and
associated infrastructure.
The proposed action has a construction footprint of 6.51 acres resulting in the physical
disturbance and permanent loss of 4.32 acres of high-quality coastal oak-beech forest, 1.19 acres
of southern successional hardwood forest, and 0.54 acres of successional shrubland (Table 6).
The loss of successional shrubland habitat is associated with the proposed 16-ft-wide haul road
traversing the site from the proposed excavation areas to Mill Road. The acreage of buildings,
impervious surfaces, and gravel driveways and parking areas is proposed to increase from 3.70
acres to 8.37 acres and would then comprise 25.4% of the site.
The Bulk Schedule requirements for properties in the M-II Zoning District require a minimum of
20% (3.29 acres) of the 16.46 acres in the M-II zone to be maintained as landscaping or natural
areas under §280 of the Town Code. Under the proposed action, 6.46 acres within the M-II zone
(51.4%) will be maintained as natural vegetation comprised of coastal oak-beech forest and
successional forest and 1.67 acres of plantings and landscaping (including retaining wall plantings).
The proposed total clearing of 7.7 (3.70 existing, 4.00 new) acres and preservation of
approximately 8.13 acres of natural vegetation within the M-II Zoning District is consistent with
and substantially exceeds the 20% minimum requirement pursuant to Town Code.
Approximately 13.77 acres of southern successional hardwood forest and successional
shrublands will be retained; these areas are located on the western R-80 zoned portion of the
property adjacent to Mill Road West. Approximately 8.28 acres of coastal oak beech forest will
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
21
be maintained on the site, largely in the northern portion of the M-II zoned property interspersed
between existing residential structures, with some forest along the southern property boundary
in the R-80 zoned portion. The approximately 0.63 acres of tidal wetlands located along the
shoreline of Mattituck Creek will be preserved under the proposed action.

a. Potential Impacts to Forest Resources
Approximately 11.76 acres of forests will be retained under the proposed action; however, 5.51
acres of the 6.51 acre development footprint currently consists of upland forest habitat. These
5.51 acres of forest area to be developed comprise 32% of the upland forests on the subject
property and 44% of the site’s coastal oak-beech forest. A tree survey of all site trees greater
than 6-inches in diameter (Appendix B) indicates that the loss of these forest areas will result
in the clearing/removal of approximately 634 trees (Table 7). The average size of the trees to be
cleared is 12.8-inches DBH. Approximately 70% of these trees consist of various oak (Quercus
sp.) and American beech trees with the remainder comprised largely of red maple, black locust,
and black cherry. The project will retain 73.7% of the trees on the subject property (i.e. 1,774
of the site’s 2,408 trees) and 54.2% of the trees in the M-II Zoning District (i.e. 735 of the M-II
area’s 1,354 trees). The coastal oak-beech forests on the subject property contain 1,647
American beech, oak, hickory, red maple, and sassafras trees; approximately 66.8% of these native
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
22
trees will be retained. Under the proposed action, approximately 66% of these site’s trees
greater than 12-inches in DBH will be preserved. In addition, approximately 135 trees will be
established in a 27,333 SF planting area along the new forest edge (predominantly pitch pine) and
small trees, such as staghorn sumac and shadbush, on the proposed retaining walls.

The Town of Southold is comprised largely of agricultural and residential land uses, which
collectively account for 63% of the Town’s land area (Town of Southold, 2017). Approximately
4,500 acres of forest cover is present within the Town of Southold based on analysis of the 2016
National Land Cover Data obtained from the Multi-Resolution Land Characteristics Consortium
(MRLC). Forest cover accounts for approximately 2.42% of the Town of Southold’s land area
interspersed within these predominantly agricultural and residential lands (Figure- LC1). The
Town’s forests are located on lands with various existing uses including open space and
recreation, residential, agricultural, and commercial land uses. The Mattituck Creek watershed
has relatively higher proportions of existing forest cover compared to the entire Town.
Specifically, forest cover is approximately 15% (340 acres) of total land area within the 2,259-acre
25-year contributing watershed of Mattituck Creek (Suffolk County Department of Health
Services, 2020) (Figure LC-2).
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
23
Ecosystem services provided by forests include providing habitat for birds and other wildlife;
maintaining groundwater and surface water quality; soil and sediment stabilization; removal of air
pollutants such as nitrogen and sulfur oxides, ozone, volatile organic compounds (VOCs), and
particulates; atmospheric carbon uptake; and groundwater recharge. The loss of these 5.0 acres
of forest will result in a reduction of the ecological benefits and ecosystem services provided by
these forests and contributes incrementally along with other forest losses in the Town and
Mattituck Creek watershed to an overall loss of forest ecosystem services. Other forest losses
in the Town are largely related to residential development, which has resulted in 5,336 new
residential units within the Town since 1980 (Town of Southold, 2017).
Potential impacts of the proposed action, including clearing of 5.51 acres of forest resources and
potential impacts to the adjacent Town Mill Road Preserve and enhanced edge effects are
discussed in Section 2.a. Potential impacts to wildlife including forest interior species, species
with large home ranges, and endangered/threatened/protected species are discussed in Sections
2.b and 2.c, respectively. Mitigation measures to offset the loss of the ecosystem services
provided by these forests are described in Section 3 (Mitigation) and include preservation of
11.76 acres of existing forest habitat (in excess of Town Code requirements); native plantings;
wildlife protection measures; and stormwater and nutrient pollution reduction.
Edge Effects
Some of the 8.28 acres of coastal oak beech forests and 3.48 acres of successional forests that
will be maintained under the proposed action will be adversely impacted by the creation of new
forest edges. Forest edges exhibit differences in microclimate, plant composition, plant density,
and habitat quality compared to forest interiors. Accordingly, forest edges are often utilized by
different wildlife and plant species compared to forest interiors. Edge habitats in forests have
higher ambient light levels, air and soil temperatures, and wind speed; and lower relative humidity
and soil moisture (Chen et al, 1995; Gehlhausen et al, 2000) than forest interiors. Studies have
found that the changes in microclimate in forests (i.e. ambient light, air and soil temperatures,
wind speed, relative humidity, etc.) occur up to 195’ from the north- and east-facing forest edges
(Gehlhausen et al, 2000; Harper et al, 2005). These changes associated with forest edges,
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
24
particularly increased light levels, foster proliferation of invasive plant species and changes to the
observed plant community due to differences in plant recruitment and survivorship (Brothers and
Spingarin, 1992; Cadenasso and Pickett, 2000). Other changes to forest processes that may occur
at forest edges include increased tree growth rates and leaf litter production due to higher light
levels (Reinmann and Hutyra, 2017), increased summer heat and drought stress to trees and
vegetation due to higher temperatures (Reinmann and Hutyra, 2017); and decreased litter
decomposition due to decreased soil moisture (Riutta et al, 2012).
The project site has 12.60-acres of coastal oak-beech forest. Due to the historical disturbances
associated with clearing for agricultural uses, commercial marine construction, and construction
of two residential structures, much of the existing coastal oak-beech forests are currently (or
were previously) subjected to edge effects from adjacent clearing or development.
Approximately 3.52 acres of the existing coastal oak-beech forests are currently located more
than 195-ft from an existing forest edge associated with the commercial marina or residential
structures. The proposed project will result in a new forest edge and, accordingly, result in
changes in microclimate that will penetrate up to 195-ft into the into the existing coastal oak
beech forests. Under post project conditions, all of the site’s 8.28 acres of coastal oak-beech
forests will be less than 195-ft from existing or new forest edges.
The new forest edge will likely result in an intensification of the existing edge effects at the site,
likely resulting in colonization and increased growth of invasive plant species (Brothers and
Spingarin, 1992) and reduction in habitat quality for nesting songbirds, and increased abundance
of predators and invasive competitors. In addition, the proposed project may result in increased
numbers of invasive birds, such as European starling (Sternus vulgaris), house sparrow (Parus
domesticus), and brown-headed cowbird (Molothrus ater), as these birds thrive in habitats created
by humans and often nest on or in buildings. Starlings compete with native birds for nest sites in
the cavities of trees, often resulting in a decline in abundance of native cavity nesters such as
woodpeckers and flycatchers (Koenig, 2000). Cowbirds are nest parasites and may have similar
adverse impacts on native birds.
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
25
After construction, mature trees that were formerly located in sheltered interior sites will be
located at or proximal to the new forest edge and, accordingly, will be exposed to increased wind
and wind-blown salt, particularly during coastal storms. Tree species that will be located at this
new edge include species that are typically tolerant of coastal conditions and wind-blown salt
(such as oaks and American beech) and/or species that are tolerant of disturbed habitats (such
as sassafras, bird cherry, and black locust). However, increased mortality in these new edge trees
is expected post construction due to windthrow, disturbance to roots/root injury, and salt
pruning.
As described in Section 3 (Mitigation), the magnitude of the potential adverse impacts of new
edge effects will be minimized by the planting of 27,333 SF of native trees and shrubs along the
new forest edge. This planted area is approximately 20-30 feet wide and will include multi-layered
plantings (i.e. plants that at maturity will occupy understory and canopy-levels) with abundant
conifer trees (i.e. seventy one pitch pine trees) to minimize light penetration into the new forest.
After establishment of these natural vegetation areas located landward of the proposed retaining
wall, the total forest area on the property will increase from 11.76 acres to 12.39 acres.
Potential Impacts to Mill Road Preserve
The subject property is adjacent to the 27-acre Town of Southold Mill Road Preserve located
between Mill Road and the residential properties on North Drive. The Mill Road Preserve has
an ecological community composition similar to the subject property with successional
shrublands and forest proximal to Mill Road and coastal oak beech forests located to the east.
The project will result in the creation of a new forest edge approximately 105 feet from the Mill
Road Preserve boundary along a short reach (approximately 99 feet) of the shared property
boundary located in the northeastern corner of the Preserve. As shown in the 1962 aerial image
(Figure 1), this area is proximal to historical disturbance associated with the clearing, filling, and
hardening of the west shoreline of Mattituck Creek on the subject property in the1950s-1960s.
The existing oak-dominated and successional forests in this portion of the property have
regenerated on the bare, exposed substrate apparent in Figure 1.
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
26
Potential adverse impacts associated with the new forest edge could include potential changes to
the forest microclimate and increased abundance of invasive plants and wildlife species, as
previously described. These edge effects are expected to extend approximately 195 feet into
Mill Road Preserve from the northeastern corner of Mill Road Preserve. The total area of the
Mill Road Preserve that may be potentially impacted by edge effects associated with the new
clearing limit on the Strong’s Yacht Center property is approximately 0.38 acres (16,419 SF).
Existing residential properties are located along the eastern border of Mill Road Preserve, as
shown in Figure 4. Therefore, some of this 0.38 acre area represents an intensification of an
existing forest edge rather than creation of a new edge. The area subject to new or enhanced
edge effects accounts for approximately 2% of the 18-acres of mature oak-beech forests in Mill
Road Preserve. Thus, the proposed action would not be expected to have significant adverse
impacts on the forest habitat quality or composition through the large majority of the Mill Road
Preserve.
Furthermore, the magnitude of potential edge effects are expected to decrease over time due to
the proposed landscaping comprised of native deciduous and coniferous trees and shrubs, such
as white oak (Quercus alba), pitch pine (Pinus rigida), staghorn sumac (Rhus typhica), and shadbush
(Amelanchier canadensis); and various woody shrubs including lowbush blueberry (Vaccinium
angustifolia), bayberry (Morella pensylvanica), and groundsel bush (Baccharis halimifolia). Proposed
edge plants will facilitate the development over time of a dense “wall” of vegetation comprised
of maintained canopy trees, regenerating trees, and shrubs to fill in open space at the edge.
“Sealing” of the edge through development of multiple layers of vegetation may reduce the
penetration of light into the forest and decrease the depth of edge impacts towards the interior
of Mill Road Preserve (Harper et al, 2005).

b. Potential Impacts to Wildlife
The decreased habitat availability associated with the loss of 32% of the site’s forest habitat will
likely decrease the abundance and diversity of the plant and wildlife species that utilize the site.
Wildlife that utilize the site’s successional shrubland and successional forest habitats will not be
adversely impacted by the proposed action due to the maintenance of 13.77 acres (approximately
89%) of these successional habitats. Similarly, wildlife species that are habitat generalists and
utilize all of the site’s habitats (i.e. successional habitats, forests, and developed areas) are also
unlikely to be adversely impacted by the proposed action, due to their general tolerance for
human activity. Examples of these habitat generalists include raccoon, opossum, and white-tailed
deer as well as birds such as American robin, common grackle, black-capped chickadee, blue jay,
and wild turkey.
Wildlife species that are most likely to be adversely impacted by the proposed action, specifically
the reduction in coastal oak-beech forest habitats from 12.6 acres to 8.28 acres, include birds or
other wildlife that inhabit mature forests, forest interiors, or have large patch size requirements.
Songbirds that are expected to utilize the site’s coastal oak-beech forests include species that
forage for insects on and under bark (such as woodpeckers and nuthatches), glean insects from
canopy foliage (such as vireos), and/or catch airborne insects (such as flycatchers and wood pee-
wees). Some bird species may be found in both small and large habitat patches, whereas other
bird species are more frequently found in larger habitat patches than smaller patches. Bird species
that are not dependent on habitat patch size and/or species that have tolerance for small habitat
patches or edge habitats are likely to continue to utilize the smaller wooded habitat patches
remaining after completion of the project. Many of the bird species that inhabit the site and have
been found to be insensitive to patch size, utilize small forest patches (between 2.0 and 8.0 acres
in area), or utilize edge habitats include American robin (Turdus migratorius), gray catbird
(Dumetella carolinensis), house wren (Troglodytes aedon), Carolina wren (Thryothorus ludovicianus),
common grackle (Quiscalaus quiscula), common flicker (Colaptes auratus), tufted titmouse,
(Baeolophus bicolor), black-capped chickadee (Poecile atricapillus), blue jay (Cynaocitta cristata),
cardinal (Cardinalis cardinalis), downy woodpecker (Picoides pubescens), hairy woodpecker
(Leuconotopicus villosus), red-bellied woodpecker (Melanerpes carolinus), white-breasted nuthatch
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
29
(Sitta canadensis), indigo bunting (Passerina cyanea), warbling vireo (Vireo glivus), great-crested
flycatcher (Myiarcgus crinitus), and American redstart (Setophaga ruticilla) (Galli et al, 1976; Garaldi,
2003; Sherri and Holmes, 1997). These species are expected to persist on the subject property,
albeit at lower abundance due to less available habitat and reduced habitat quality in remaining
forests resulting from intensification of adverse edge effects, including increased abundance of
nest predators and nest parasites.
Forest bird species that are patch-size dependent during the breeding season and require
relatively large habitat patches or utilize the interior of forest habitat patches, such as red-eyed
vireo (Vireo olivaceous), ovenbird (Seiurus aurocapilla), black-and-white warbler (Mniotilta varia),
veery (Catharus fuscescens), wood thrush (Hylocichla mustelina), and scarlet tanager (Piranga
olivacea) (Galli et al, 1976; Banner and Schaller, 2001) are less likely to utilize the site after the
reduction from 12.60 to 8.28 acres of coastal oak-beech forest. As discussed below, the existing
forest patches at the site are too small for successful breeding of the most area sensitive forest
birds, such as wood thrush and scarlet tanager, and edge effects related to nest predation and
nest parasitism are likely already pervasive. The suitability of the site for some forest breeding
birds may be lost as the available habitat, 8.28 acres, drops below the published habitat patch size
requirements for species such as red-eyed vireo (Vireo olivaceous), ovenbird (Seiurus aurocapilla),
and black-and-white warbler (Mniotilta varia). However, these patch size-dependent bird species
are likely to continue to utilize the approximately 18-acres of coastal oak-beech forest on the
adjacent Mill River Preserve, as well as smaller habitat patches during the spring and fall migrations
(Keller and Yahner, 2007).
The loss of the 5.51 acres of on-site forest contributes incrementally along with other forest
losses in the Town to a decrease in the number of habitat patches that are large enough to
support stable populations of forest birds (Nol et al, 2005). Other forest losses in the Town are
largely related to residential development, which has resulted in 5,336 new residential units within
the Town since 1980 (Town of Southold, 2017).
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022

None of the songbird species expected to utilize the subject property are listed as Endangered,
Threatened, or Species of Special Concern in New York State. Most of the bird species present
on the subject property are not listed on the US Fish and Wildlife Species Birds of Conservation
Concern list (USFWS, 2021). In addition, the patch-size dependent bird species identified above,
red-eyed vireo (Vireo olivaceous), ovenbird (Seiurus aurocapilla), and black-and-white warbler
(Mniotilta varia), are not identified as Birds of Conservation Concern by the US Fish and Wildlife
Species (USFWS, 2021). Accordingly, the displacement or loss of habitat at the site for individuals
of these abundant bird species, even those that are patch-size dependent, is not likely to adversely
impact the regional populations of these species.
Many songbird populations have been declining in abundance in the Northeastern United States
since the 1970s (Rosenberg et al, 2019). Two songbirds that may potentially utilize the site as
breeding habitat are listed as “Species of Greatest Conservation Need” in New York State.
Species of Greatest Conservation Need are species that are experiencing some level of
population decline, have identified threats that may put them in jeopardy, and need conservation
actions to maintain stable population levels or sustain recovery. The two songbird species that
are classified as Species of Greatest Conservation Need that are expected to utilize the site are
wood thrush (Hylocichla mustelina) and the scarlet tanager (Piranga olivacea). Wood thrushes
typically breed in deciduous forests with an abundance of saplings and high density of tall shrubs
(DeGraaf and Rappole, 1995; Roth et al, 1996). Wood thrushes may breed in small habitat
patches (2.5 to 12.5 acres) or smaller (Robbins et al, 1989, DeGraaf and Rappole, 1995), but have
been found to have lower nest productivity in these small habitat patches due to nest predation
by cowbirds, jays, crows, raccoons, and domestic and feral cats (Weinberg and Roth, 1998).
Scarlet tanagers prefer mature deciduous and mixed forests with tall trees, moderately open to
closed canopy, and well-developed understory (Lambert et al, 2017). Scarlet tanagers breed
successfully in large habitat patches. Habitat patches in landscapes with 50% or less forest cover
must be 30-170 acres in area to be moderately to highly suitable for tanager breeding (Rosenberg,
2014).
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
31
The site does not provide high quality breeding habitat for wood thrush or scarlet tanager due
to 1) the paucity of understory vegetation, 2) the relatively small area of the existing forest patch
(12.60 acres on property and ~37 acres with adjoining Mill Road Preserve), and 3) nest predation
due to proximity to existing forest edges and human development. Thus, the loss of the 4.32
acres of coastal oak-beech habitat resulting from the proposed action will reduce habitat for
foraging (particularly during migration periods) for these species, but not result in the loss of
high-quality nesting habitat that would significantly adversely impact the populations of these two
species of Conservation Need.
The potential for the proposed action to generate noise from construction activities, vehicular
traffic, and operation of the proposed boat storage facility is analyzed in detail in the project
Acoustic Report. This analysis indicates that existing noise conditions within the natural ecological
communities on the subject property are between 40-45 dBA. Analysis of potential noise levels
at nearby residential sites (such as 5106 West Mill Road, 800 North Drive, and 805 North Drive)
indicate that noise levels in the property’s natural areas may increase temporarily during project
construction to 66 dBA during tree removal/grubbing (in December), 76 dBA during excavation
phases (between December to June), and 71 dbA during building and drainage construction
phases (between June to November). Under the proposed build conditions, noise levels are
expected to increase slightly by 0-4 dbA to 44-48 dbA. Under proposed build conditions, sound
levels will not increase by more than 6 dBA above existing conditions and, therefore, is consistent
with “no impact” following NYSDEC standards for impacts to human receptors.
Noise pollution associated with industrial activities, roads, and major highways has been found to
result in ecological impacts such as lower bird breeding densities and poorer body condition. For
example, chronic industrial noise levels of 75-90 dbA generated by compressor stations on
natural gas pipelines in Alberta, Canada resulted in a 15% decrease in the observed breeding
ovenbirds pairs (Seiurus aurocapilla) in forests adjacent to the compressor stations (Habib et al
2007) and 15-66% decrease in other species including red-breasted nuthatch (Sitta canadensis),
red-eyed vireo (Vireo olivaceous), and yellow-rumped warbler (Dendroica coronata) (Bayne et al,
2008). Anthropogenic noise was also found to increase stress and reduce body condition in
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
32
songbirds, but not adversely impact survivorship, in urban habitats compared to more rural
habitats (Phillips et al, 2018). Simulated roadway noise that increased noise levels (Leq) by 11-20
dBA experienced by birds was found to alter the species composition and abundance of the avian
community, alter foraging and nesting behavior, and reduce nestling body condition (Injaian et al,
2007; Ware et al, 2015). Potential impacts to birds adjacent to these industrial facilities and
simulated roadway noise was attributed to increasing stress levels; noise interference with bird
songs used to attract mates and defend breeding territories; and altered foraging and nesting
behavior (Reijnen et al, 1995; Habib et al, 2007).
Over the long-term, the maximum projected noise levels would remain under 50 dBA and would
not increase by more than 4 dBA compared to existing conditions. This increase in noise levels
under the Proposed Action are less intense than the industrial sources and simulated roadway
noise (more than 11 dBA change in noise levels) that have been documented in the scientific
literature to adversely impact birds; thus, no long-term noise-related impacts to birds and bird
habitat expected to result from the operation of the proposed boat storage facility.
Potential noise levels during the 12-month construction period (45-76 dbA compared to 44 dBA
under existing conditions) slightly overlap with the range of the chronic industrial levels (75-90
dbA) that have been found to impact bird breeding productivity (Habib et al, 2007) and are similar
to the change in sound levels (11-20 dBA) that have been found to adversely impact bird
community composition and abundance, foraging and nesting behavior, and body condition
(Injaian et al, 2007; Ware et al, 2015). Accordingly, it is expected that a temporary reduction in
the habitat quality provided by the adjacent forest for bird reproduction will occur during
construction.
Mitigation measures to lessen the magnitude of short-term, noise-related impacts during
construction to neighbor are discussed in Acoustic Report and include use of white noise back-
up alarms rather than single, tone beeps; no use of Jake Brake mechanisms on site; and use of
dump trucks that meet USEPA Tier 4 standards. These mitigation measures will serve to reduce
potential impacts to birds and wildlife by decreasing high frequency noise.
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
33
No adverse impacts to wildlife or wildlife habitat are expected to result from new outdoor
lighting associated with the proposed action. The proposed lighting shall be dark skies-compliant,
downward directed lighting resulting in no increase in light levels beyond the limit of the proposed
buildings, access roads, and parking surfaces.
c. Potential Impacts to Endangered, Threatened, Rare Species or Significant
Ecological Communities
No endangered, threatened, or rare species or significant ecological communities were observed
during the ecological surveys conducted. New York Natural Heritage Program (NYNHP)
correspondence from December 1, 2020 indicates that piping plover (Charadrius melodus), a New
York State threatened species, is the only record of a known occurrence of a rare or state-listed
animal or plant or significant natural community on or in the vicinity of the site (Appendix A).
Piping plovers nest at Breakwater Beach located more than 0.5 miles away on the west side of
Mattituck Inlet. No breeding or foraging habitat for piping plover is present on the site and,
accordingly no impacts to piping plover would result from the proposed action.
The NYSDEC EAF Mapper (https://gisservices.dec.ny.gov/eafmapper/) indicated the potential for
southern sprite (Nehalennia integrecollis), a damselfly listed as a Species of Special Concern in New
York State, to occur in the vicinity of the project site. Southern sprite are found in coastal plain
ponds on Long Island (NYNHP, 2010). Due to the absence of suitable habitat, southern spite are
not expected to occur on the subject property and no impacts to this species will result from
the proposed action.
As described in Section 2.b (Wildlife), the site contains habitat that could be utilized by the
northern long-eared bat (Myotis septentrionalis) during the summer months for foraging and
diurnal roosting. The northern long-eared bat was listed as threatened by both the US Fish and
Wildlife Service and New York State in 2016 due to population declines caused by white-nose
syndrome (WNS), a disease caused by an invasive fungus that kills affected hibernating bats during
the winter months. The availability of summer habitat is not limiting for northern long-eared bat.
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
34
Accordingly, loss of summer habitat is not recognized as a threat to the conservation of this
species (USFWS, 2016); rather, white-nose syndrome is the primary threat to northern long-
eared bat within its summer habitats.
Due to the presence of suitable summer roost habitat at the site and documentation of northern
long-eared bat foraging over various habitat types throughout eastern Suffolk County, the
NYSDEC recommends that any cutting of trees occur during the winter months (between
December 1 and February 28) to avoid a potential take of this protected species. Any cutting of
trees associated with this project would occur during this timeframe in accordance with NYSDEC
recommendations and, accordingly, no adverse impacts to northern long-eared bat populations
are expected to result from the proposed action. Winter cutting of forest trees would also
minimize potential impacts to breeding wildlife and birds.
Three species listed as Species of Special Concern by New York State are expected to occur
on or utilize the site. These three species include:
Eastern Box Turtle Terrapene carolina
Cooper’s Hawk Accipiter cooperii
Sharp-shinned Hawk Accipiter striatus
Eastern box turtle are expected to be found in any of the vegetated upland habitats on the site.
The project would result in a loss of approximately 6.05 acres of upland forest and shrubland
habitat for eastern box turtle. Potential adverse impacts to eastern box turtle will be avoided or
minimized by conducting sweeps or surveys for box turtles prior to commencement of clearing,
grading, and excavation activities, and relocation of any observed turtles to on-site areas that will
not be disturbed. Silt fencing or other barriers will be installed around work areas to prevent
turtles from returning to construction areas.
Cooper’s hawk (Accipiter cooperii) and sharp-shinned hawk (Accipiter striatus) inhabit various upland
and wetland forests during the breeding season, including fragmented forests within agricultural,
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
35
suburban, and urban landscapes, and with sharp-shinned hawks preferring forest edge habits.
Cooper’s hawks breeding sites have been expanding in New York over the last several decades.
Cooper’s hawks prefer to nest in forests with a closed canopy, trees that are more than 30 years
old, and moderate to heavy shrub cover (Beans and Niles, 2003). The site’s coastal oak-beech
forest provides suitable, but not optimal, nesting habitat due to the relative absence of shrub
cover. Sharp-shinned hawks were not documented to nest anywhere in Nassau or Suffolk
Counties by McGowan and Corwin (2008). During the winter months, both species frequent
residential areas to hunt for songbirds at bird feeders. Both species are expected to utilize the
subject site as foraging habitat during any season. The proposed action will result in a loss of
foraging habitat and degradation of habitat quality for Cooper’s hawk (Accipiter cooperii) and sharp-
shinned hawk (Accipiter striatus), although these species will likely continue to hunt the human-
tolerant songbirds and doves that will utilize the developed property and the remaining 22.05
acres of coastal oak-beech forests and successional habitats.
d. Potential Impacts to Tidal Wetlands
No physical disturbance to the small area (0.63-acres) of intertidal marsh and high marsh tidal
wetlands on the southern end of the property is proposed and, accordingly, there will be no loss
of tidal wetland area resulting from the proposed action.
Construction and waterfront development actions may result in indirect impacts to adjacent and
proximal wetlands through stormwater runoff (both during construction and under future
conditions) that may transport sediments or pollutants to these wetlands, increased nutrient
loading to surface waters and wetlands from sanitary systems, and erosion due to increased vessel
wakes. The wetlands and surface waters of Mattituck Creek are designated as a Significant
Coastal Fish and Wildlife Habitat and threats to these wetlands identified by the New York State
Department of State include any activity that would substantially degrade the water quality in
Mattituck Creek or would adversely affect the biological productivity of this area including
chemical contamination, oil spills, excessive turbidity, and waste disposal (including vessel wastes).
Long Island’s tidal wetlands are also adversely impacted by other factors including sea level rise,
eutrophication of estuarine waterbodies (Deegan et al, 2012), low sediment supply, expansion of
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
36
invasive Phragmites australis, erosion caused by recreational and commercial vessel wakes, and
other factors.
The proposed action provides multiple mitigation measures and best management practices to
minimize the potential for adverse impacts to the 0.63-acres of on-site tidal wetlands and the
approximately 60 acres of tidal wetlands located in Mattituck Creek.
The seaward edge of tidal marshes along creek banks, particularly in large tidal channels such as
Mattituck Creek, are subject to erosional forces from wind-driven waves during storms and
vessel wakes. Mattituck Creek is subject to a 5-mph (no wake zone) enforced by the US Coast
Guard and Town of Southold Bay Constable to maintain safe navigational conditions. No wake
zones reduce the potential for the erosion of marsh edges due to vessel wakes.
Furthermore, the proposed action will not substantially increase vessel traffic within Mattituck
Creek. The proposed action includes two buildings for the purpose of winter boat storage. The
project does not include the use of these buildings year-round, does not propose year-round
boat traffic in an out of SYC, does not propose any additional docks, nor does it propose the use
of any existing facilities at SYC to house boats that arrive to the site for storage. It is estimated
that approximately 88 boats per off-season would be stored in the new buildings. Accordingly,
given an eight-week timeframe for entry to storage in the fall and the same timeframe to remove
boats from storage in the spring, this equates to an average of approximately 11 boats per week
or less than two boats per day. Averaged annually, the total 176 trips (88 boat trips in the spring
and 88 boat trips in the fall) equates to 0.48 boat trips per day. It is estimated that approximately
547 boats are active in Mattituck Creek on a peak season day. Therefore, the increase in vessel
traffic of 0.48 boat trips per day is nominal and the potential for increased erosion of tidal marshes
due to vessel traffic is not significant.
The proposed action provides for stormwater management that will serve to minimize potential
for degradation of existing tidal wetlands and water quality through nutrient or sediment
pollution. The proposed development shall be constructed under the requirements and
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
37
specifications of a Stormwater Pollution Prevention Plan (SWPPP) prepared in accordance with
the New York State Department of Environmental Conservation (NYSDEC) SPDES General
Permit No. GP-0-20-001 and Chapter 236 "Stormwater Management” of the Town of Southold
Code. The site’s SWPPP includes both permanent and temporary best management practices to
minimize potential impacts from stormwater runoff to surface waters of the site’s wetlands and
Mattituck Creek. Temporary best management practices will also be employed to prevent
erosion and transport of sediments, litter, and debris during construction actions, and include silt
fences, silt sack inlet protection, soil stockpile protection measures, temporary seeding and
mulching, stabilized construction entrances, and designated concrete wash-out areas.
Permanent infrastructure practices installed to collect, treat, and infiltrate stormwater shall
include stormwater catch and leaching basins and French drains to collect stormwater runoff
generated by a 2-inch rainfall event from the roofs of the proposed buildings. Two of the existing
metal warehouse buildings will also be connected to the proposed stormwater management
infrastructure, reducing transport of sediments, nutrients, and pollutants to Mattituck Creek from
these existing structures.
Nutrient loading to adjacent surface waters has adverse impacts to tidal wetlands due to potential
smothering of wetland grasses by rafts of marine algae, increased marsh bank instability, and
expansion of invasive Phragmites at the landward edge of marshes. Strong’s Yacht Center
operates a pump-out vessel to minimize potential for unauthorized discharge of waste holding
tanks and maximize compliance with the Mattituck Harbor and Long Island Sound No Discharge
Zones. Nutrient reduction measures included in the proposed action include the replacement
and up-grade of the existing conventional sanitary system that services the existing office, marina,
and other buildings with an I/A OWTS, and a new I/A OWTS to service the proposed boat
storage buildings. Both new I/A OWTS shall conform with the Suffolk County Sanitary Code and
are designed to reduce total nitrogen in treated effluent to 19 mg/L and remove an average of
70% if influent nitrogen concentrations. The proposed I/A OWTS upgrades ensure that the
proposed action does not contribute additional nutrient loading to Mattituck Creek (and
potential adverse impacts to wetlands) and represents an improvement compared to nutrient
loading under existing site conditions.
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
38
No significant adverse impacts to tidal wetlands located on-site or within Mattituck Creek are
expected to result from the proposed action. No physical disturbance to tidal wetlands is
proposed, and the project provides for mitigation measures that will contribute to potential
surface water quality and habitat quality improvements in Mattituck Creek, such as new I/A
OWTS’s and new stormwater drainage infrastructure.
3. Mitigation
The following measures have been incorporated into the proposed development to mitigate the
potential adverse impacts to ecological resources including forests, wildlife, and wetlands.
• Approximately 8.28 acres of coastal oak-beech forests on the subject property
(approximately 66% of the existing 12.60 acres) will be retained. These remaining coastal
oak-beech forests retain 70% of the site’s oak (Quercus sp.), American beech (Fagus
grandifiolia), red maple (Acer rubrum), hickory (Carya sp.), and sassafras (Sassafras albidum)
trees.
• Overall, the project retains 11.76 acres of forest habitat (comprised of coastal oak-beech
forest and successional forests), 75.4% of the site’s approximately 2,400 trees, and 70.6%
of all trees greater than 12-inches in diameter.
• To mitigate for the loss of forest trees associated with the project, approximately ninety
five pitch pine trees, will be planted. These trees (minimum 4-5 ft height) will be planted
along the western edge of the proposed development. In addition, the applicant will
contribute fifty (50) native trees (10-gallon container typical 1-inch caliper, 5-6 ft tall) for
installation at high-priority sites with the Town of Southold, as identified by the Town
Tree Committee, to enhance and beautify public grounds.
• The proposed project will shift the eastern edge of the existing forests up to 520-ft to
west. Forest edges have degraded habitat quality due to changes in microclimate,
increased growth of invasive plant species, and increased abundance of predators and
invasive competitors. Potential edge effects and habitat degradation in the retained forests
on the subject property and the Town of Southold Mill Road Preserve will be minimized
by:
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
39
o Planting 27,333 SF of native trees and shrubs along the new forest edge. This
planted area is approximately 20-30 feet wide and will include dense, multi-layered
plantings (i.e. plants that at maturity will occupy understory, and canopy-levels)
with abundant conifer trees (i.e. 71 pitch pine trees) to minimize light penetration
into the new forest. After establishment of these natural vegetation areas located
landward of the proposed retaining wall, the total forest area on the property will
increase from 11.76-acres to 12.38-acres.
o The proposed retaining wall features topsoil-filled planting trays that will planted
with native ground-vegetation, shrubs, and small trees. Native plant species that
will be planted on the retaining wall include bayberry (Morella pensylvanica),
staghorn sumac (Rhus typhina), shadbush (Amelanchier canadensis), groundsel bush
(Baccharis halimifolia), Virginia creeper (Parthenocissus quinquefolia), switch grass
(Panicum virgatum), and common milkweed (Asclepias syriaca). The vegetation
established on the proposed retaining wall will serve to further reduce the
intensity of the new forest edge.
• The proposed activities include construction of a stormwater management system that
will collect, treat, and infiltrate stormwater generated from a 2-inch rainfall event from
the roofs of the proposed buildings. Stormwater management infrastructure shall include
catch and leaching basins and French drains. Two of the existing metal warehouse buildings
will also be connected to the proposed stormwater management infrastructure, reducing
transport of sediments, nutrients, and pollutants to Mattituck Creek from these existing
structures.
• Nutrient reduction measures included in the proposed action include the replacement
and up-grade of the existing conventional sanitary system that services the existing office,
marina, and other buildings with an I/A OWTS, and a new I/A OWTS to service the
proposed boat storage buildings. Both new I/A OWTS shall conform with the Suffolk
County Sanitary Code and are designed to reduce total nitrogen in treated effluent to 19
mg/L and remove an average of 70% if influent nitrogen concentrations. The proposed
I/A OWTS upgrades ensure that the proposed action does not contribute additional
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
40
nutrient loading to Mattituck Creek (and potential adverse impacts to wetlands) and
represents an improvement compared to nutrient loading under existing site conditions.
• All tree clearing for the proposed action will occur during the winter months (between
December 1 and February 28) in accordance with NYSDEC guidance to avoid potential
impacts to the New York State-threatened northern long-eared bat (Myotis
septentrionalis), as the site’s forests provide suitable summer roost habitat for this species.
• To avoid or minimize potential impacts to eastern box turtle, sweeps or surveys for box
turtles will be conducted prior to commencement of clearing, grading, and excavation
activities, and any observed turtles will be relocated to areas that will not be disturbed.
Silt fencing or other barriers will be installed around work areas to prevent turtles from
returning to construction areas.
4. Analysis of Alternatives
Alternate Plan (Minimum Fill Export Alternative)
The Alternate Plan (Minimum Fill Export Alternative) includes the as-of-right construction of two
boat storage buildings (52,500 square feet and 49,000 square feet, respectively) on the higher
elevation areas on the western portion of the M-II zoned area without the cut/removal of 135,000
cubic yards of substrate necessary to bring the site to El. 10.0. This Alternative requires a net
cut/fill of 2,984 cubic yards. Under this Alternative, existing Buildings 7 and 8 (15,076 SF and
22,245 SF, respectively would be increased in height to accommodate large boats. Alternative 4
would also include ~2,050 lf of concrete retaining walls (up to 29-ft in height), a paved 20-ft wide
road to access the new buildings, additional gravel-based driveway and parking surfaces, water
supply, sewage disposal using new I/A OWT systems, site grading and drainage, landscaping, and
lighting.
The potential ecological impacts of the Alternate Plan are broadly similar to the proposed action.
The Alternate Plan results in the loss of 4.75 acres of upland forest habitat (3.89 acres of coastal
oak-beech forest and 0.86 acres of successional hardwood forests), refer to Table 8, compared
to 5.51 acres of forest disturbance under the proposed action (Table 6). Similarly, the Alternate
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
41
Plan results in slightly less clearing/removal of trees; approximately 612 trees will be cleared
under the Alternate Plan compared to 634 trees under the proposed action. The project will
retain 74.6% of the trees on the subject property under the Alternate Plan compared to 73.9%
of trees under the proposed action. The 74.6% of retained trees represents 1,796 of the site’s
2,408 trees and 56.3% of the trees in the M-II Zoning District (i.e. 762 of the M-II area’s 1,354
trees).

Total Site 32.96 100.0% 32.96 100.0%
Accordingly, potential project impacts related to lost wildlife habitat and forest ecosystem
services are slightly less under the Alternate Plan. Potential project impacts to Mill Road Preserve
(discussed in Section 2.a) are also similar between the proposed action and the Alternate Plan,
due to the similar minimum distance between clearing limit and the Mill Road Preserve property
boundary, approximately 103-ft and 105-ft, respectively. The potential ecological impacts of the
Alternate Plan to wildlife, forests, tidal wetlands, and endangered/threatened species are expected
to be broadly similar to the potential impacts of the proposed action discussed in Section 2.a
(Forest Resources), Section 2.b (Wildlife), Section 2.c (Endangered/Threatened Species), and
Section 2.d (Tidal Wetlands), Mitigation measures, similar to those described in Section 3, would
also be employed under the Alternate Plan.
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022

Alternate Plan 7 (Alternative Material Mitigation Plan)
An alternative material mitigation plan has been evaluated to reduce the volume of material to
be removed from the subject property by placing approximately 13,500 cy of material on the R-
80-zoned parcel. The resultant impact on transportation would be the elimination of 450 trucks
from the excavation phase, which would reduce the excavation phase by 11.25 days or
approximately two weeks (as the proposed excavation phase would occur Monday – Friday only).
The material would be placed within an 8.60-acre portion of the successional shrublands located
on the R-80 zoned parcel. Fill would be placed at a depth of approximately 12 inches above the
existing grade throughout the 8.60-acre placement area. The northern and eastern margins of
the fill placement area correspond to existing earthen access paths. No material will be placed
within 25-ft (minimum) from existing stands of trees within the Successional Southern Hardwood
forest areas. The setback of the proposed fill placement area is 25 to 75 ft from the northern
property boundary, 75 to 200 ft from the southern property boundary, and 35 to 100 ft from
the eastern property boundary.
The successional shrublands at the site are dominated by autumn olive (Elaeagnus umbellata) with
thickets of brambles (Rubus phoenicolasius, Rubus allegheniensis, and Rubus flagellaris) and multiflora
rose (Rosa multiflora). Native and old field grasses and wildflowers including various goldenrods
are present along the maintained margins of trails and paths. Invasive fountain grass (Miscanthus
sp.) was also common. The site’s successional shrublands contain many small stands of
successional trees, mostly black cherry (Prunus serotina) and eastern red cedar (Juniperus
virginiana), with heavy infestations of Asiatic bittersweet (Celastrus orbiculatus). This successional
shrubland habitat has developed on the site since the abandonment of agricultural uses in the late
1980s and is similar to ecological composition of many former agricultural sites in Suffolk County.
Under Alternative Plan 7, the ground- and shrub-level vegetation within the successional
shrubland would be cut to close to ground level and the approximately 12-inches of sand/sandy
loam soils from the excavation area would be placed on the existing grade. The cut aboveground
biomass from existing herbaceous vegetation, woody vines and brambles, small woody shrubs
and trees (i.e. less than 6-inches in DBH) would collected and removed before spreading of
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
43
material. The new sandy soils would be seeded with a native upland grassland seed mix comprised
of native warm season grasses, such as switch grass (Panicum virgatum), Indian grass (Sorghastrum
nutans), and little bluestem (Schizachyrium scoparium). These warm-season grasses provide high
quality habitat for wildlife (including grassland birds, small mammals, and raptors)--including food
resources, nesting sites, and cover during winter months.
The dominant shrubs and vines currently present in the successional shrubland will also re-
colonize the seeded fill placement area over time due to 1) seed dispersal by birds and small
mammals and 2) some limited re-sprouting of woody trees and shrubs from cut stumps through
the shallow sandy soil.
There are approximately 155 trees (greater than 6-inches in DBH) located within the 8.6-acre
placement area. Eastern red cedar (Juniperus virginiana) and black cherry (Prunus serotina) trees
comprise 43 and 32% of these trees within the proposed placement area. These red cedar and
black cherry trees within the placement area range in size from 6-inches to 16-inches in diameter
and many of these trees have heavy infestations of invasive vines, specifically Asiatic bittersweet
(Celastrus orbiculatus), wrapping around their stems and smothering canopy foliage. Other tree
species present at lower abundance within the proposed placement areas include black locust
(Robinia pseudoacacia), tree of heaven (Ailantus altissima) and scattered oaks (Quecus sp.), Norway
maple (Acer platanoides), gray birch (Betula populifolia), and autumn olive (Elaeagnus umbellata).
Placement of fill and operation of construction equipment can result in injury to tree roots
including decreased oxygen supply to roots and impeded gas exchange between roots and air
within soil pores. In order to avoid impacts to the root systems of trees within the proposed
placement area, no fill will be placed within 3 to 10-ft of existing tree stems (depending on the
size of the tree).
Similar to the proposed action, the Alternate Plan 7 results in the loss of 5.51 acres of upland
forest habitat (4.32 acres of coastal oak-beech forest and 1.19 acres of successional hardwood
forests), refer to Tables 6 and 9. Under Alternate Plan 7, an additional 8.60 acres of the
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
44
successional shrubland would be disturbed through clearing of existing vegetation and placement
of sandy loam fill. After establishment ground coverage of the placed material through seeding
of warm season grasses, there would be no substantial difference in the ecological community
composition of the subject property under Alternate Plan 7 compared to the proposed action.
After several growing seasons, the plant community composition of the Successional Shrubland
areas under Alternate Plan 7 would likely be similar to existing conditions, albeit with a larger
component of native warm season grasses, due to the re-sprouting of woody trees and shrubs
from cut stumps through the placed fill and re-colonization of these species through seed
dispersal. Due to the likely increase in warm season grass coverage under the Alternate Plan 7
(in the short term), the ecological community designation for these areas was changed to
Successional Shrubland and Successional Old Field.

Alternate Plan 7 (Alternative Material Mitigation Plan) would increase short-term impacts to
wildlife, such as small mammals and reptiles, including Eastern Box turtle, compared to the
proposed action, as this alternate would increase the area of project disturbance by
approximately 8.6 acres and include the successional shrubland that was largely excluded from
construction activities under the proposed action. It is expected that there would be mortality
to small mammals and herptiles during clearing and grading activities, although some organisms
would likely successfully shelter in underground burrows. With the exception of Eastern Box

turtles, the small mammals and herptiles that inhabit the site’s successional shrublands consist of
abundant species with stable populations and, accordingly, the displacement or mortality of
individuals at the site are not likely to adversely impact the regional populations of these species.
Alternate Plan 7 (Alternative Material Mitigation Plan) would result in the loss of approximately
6.05 acres of upland forest and shrubland habitat for eastern box turtle and temporary
disturbance to an additional 8.60 acres of successional shrubland habitat. Potential adverse
impacts to eastern box turtle will be minimized by conducting sweeps or surveys for box turtles
prior to commencement of clearing, grading, and excavation activities, and relocation of any
observed turtles to on-site areas that will not be disturbed. Silt fencing or other barriers will be
installed around work areas to prevent turtles from returning to construction areas.
The new successional meadow habitat created after fill placement and establishment of warm
season grasses would provide higher quality habitat compared to the existing conditions.
However, this habitat improvement is expected to be temporary (i.e. several years to a decade
or more) as the recruitment of invasive species such as autumn olive (Elaeagnus umbellate),
multiflora rose (Rosa multiflora), and Asiatic bittersweet (Celastrus orbiculatus) will return the
proposed placement area to its existing conditions over time.
Under the Alternate Plan 7, the approximately 155 trees, predominantly eastern red cedar and
black cherry trees, will be preserved within the 8.60-acre material placement area. Potential
adverse impacts to these trees will be minimized by maintaining a 3 to 10-ft diameter tree
protection area (depending on tree diameter) around each tree where no material placement or
equipment operation will occur. As discussed previously, many of these trees are in poor
condition due to extensive loads of invasive vines, specifically Asiatic bittersweet. Due to these
tree protection measures, the proposed tree clearing under Alternate Plan 7 will be similar to
the Proposed Action described in Table 7.
Strong’s Yacht Center: Ecological Conditions and Impact Analysis October 2022
46
Potential project impacts to Mill Road Preserve (discussed in Section 2.a) are similar between the
proposed action and the Alternate Plan 7, due to the similar minimum distance between clearing
limit and the Mill Road Preserve property boundary.
The potential ecological impacts of the Alternate Plan 7 to forests and forest wildlife, are expected
to be broadly similar to the potential impacts of the proposed action discussed in Section 2.a
(Forest Resources) and Section 2.b (Wildlife), as there are no differences in project scope
between Alternate Plan 7 and the proposed action within these forest areas. Mitigation measures,
similar to those described in Section 3, would also be employed under the Alternate Plan.
The potential ecological impacts of the Alternate Plan 7 to tidal wetlands are expected to be
broadly similar to the potential impacts of the proposed action discussed in Section 2.d (Tidal
Wetlands). Mitigation measures, similar to those described in Section 3, would also be employed
under the Alternate Plan.
