PRO3ECT PURPOSE, NEED AND BENEFITS
THE AFFORDABLE HOUSING CRISIS IN OUR COMMUNITY
One of the crucial
Southold today is
The problem is so
problems facing the Town of
the lack of affordable housing.
severe that, within the last
three years, the Town has studied the problem and
enacted an "AFFORDABLE HOUSING DISTRICT" in the
Town's zoning ordinance. The average building lot
in Southold today now costs $80,000.00 and a home
$190,000.00 These costs have driven the working
class from our community. As a result, Southold
is becoming a second bedroom community. To date.
the only successes in the area of affordable
housing have been in the form of subsidized
housing where government has donated free land.
Unfortunately, these efforts have not met the
needs and expectations of the community in
providing the number of housing units necessary.
The estimated number of affordable housing units
needed for Southold Town is )~0 to ~15. (See
Appendix No. 5.>
The proposed project is not subsidized by any
governmental agency. It is created by private
capital to bring housing for the public good.
Upon completion, Southold Town will have at least
27 single family affordable homes which will have
been created without any cost to the town or its
taxpayers. In fact. the proposed projsct will add
to the town's tax base, and it will bring new li~e
and vitality to the community.
The project proposes a different concept than has
been previously attempted. The property will be
subdivided into liberal half to one acre parcels.
Twenty-seven (Z7) of these parcels shall be sold
under the affordable guidelines. These parcels
will not be separated but rather intermingled with
the remaining parcels making one con~nunity. The
affordable homes will consist of a minimum of 1ZOO
square feet, have three bedrooms and a full
basement. The homes will be designed identical to
the balance of the project, but will be sold well
under market value.
The p~oposed project will lessen a major problem
in the Town of Southold without creating any
additional ones. The project is designed to be a
showcase for affordable housing and a credit to
the community. It will be the beginning of the
solution - a solution that will benefit Southold
Town and it's people for years to come.
The project location next to the hamlet of
Southold is consistent with the goals of the
proposed Master Plan to have hamlet density
housing in close proximity to existing hamlets.
B. LOCATION OF PROPOSED PRO3ECT
As previously stated, the 37.76Z Acre parcel
proposed for rezoning'~and development is located on
the Easterly side of Boisseau Avenue,
approximately ],200 feet South of County Road 40.

C. DESIGN AND LAYOUT
The site will be sub-divided into ?ifty-?ive (~)
housing lots of 20,000 to 40,000 square feet each,
with an average size of approximately 2Z.O00
square feet each exclusive of streets, and
designated open areas.
Streets are proposed to be twenty-eight (ZS> feet
wide. constructed in accordance with the Town of
Southoid Highway Specifications, and to include
curbs on either side with catch basins and storm
drains discharging to a drainage pond to take full
advantage of the recharge capability of the well
drained so~l on this particular site.
The Affordable Housing lots will be serviced by
Greenport Village water, Long Island Lighting
Company, New York Telephone, and Dimension Cable

]o ~roundwa~er
Groundwater, as previously discussed, is the
principal water resource of concern in an area
such as Long Island that has been classified by
the EPA as being fully dependent upon a sole, or
single, source for its potable water supply.
This designation reinforces the in-place
planning criteria and monitoring activities that
are utilized to ensure that the groundwater not
be contaminated by either point- or non-point
sources of pollution. The concern is even more
critical in the Town of Southold for, unlike
many other areas of Long Island. potable water
supply is not Available here from both the
Glacial and Magothy Aquifers. Water underlying
Southold within the MAgo%hy formation ie
generally too saline for potable use.
Sands and gravel of the particular soils
previously discussed Are characterized as highly
permeable and yield little run-off during
precipitation periods. The upper ]evels of

TERRESTRIAL AND AQUATIC ECOLOGY
1. Vegetmtion
The parcel proposed for rezoning and development
is considered abandoned farm land and is
characterized by a limited amount of secondary
vegetation that has begun to reclaim an area of
early agriculture crop use. Most of this area
is brush type and is young and sparce throughout
most o~ the site. Species encountered are
the following:
Bayberry Groundsel
Locust Red Maple
Sumac Oak
Red Cedar
Bush

Native grasses predominate and provide ground
cover throughout the entire parcel. Adjacent
residential properties typically have landscaped
lawns, plants, planted shrubbery, and a variety
of common trees such as maple and oaks.
2. Fish, Shellfish and Wildlife
Animal Ii~e occupying the site are largely those
small species associated with near-residential
and open field conditions. Representative
species either observed on-site or or likely
to inhabit the wooded ares and its borders
include the following:
Meadow Mouse
White Footed Mouse
House Mouse
Cottontail Rabbit
Meadow Vole
Norwegian Brown Rat
Various birdlife is also commonly found on and
adjacent to the subject parcel. These include
sparrows, flickers, blackbirds, chickadees.

HUMAN RESOURCES
The principal human or built resources which contribute to
the environmental setting or context of a particular site are
its transportation accessibility, existing land use and
zoning controls which guide its future development, the
community services and {acilities available at the location,
its demographic conte×t and cultural resources that may be
present.
A. TRANSPORTATION
Transportation Services
The principal transportation arteries
servicing the North Fork of Long Island are
Middle or North Road (County Road 48> and Main
Road (New York State Route Z~). Route Z~, an
East-West roadway, is a two-lane improved
roadway passing through the hamlet centers of
the North Fork, including Mattituck, Cutchogue
and Southold within the Town of Southold, and
the Village of Greenport. Middle. or North
Road. (County Road 48), also an East-West
artery, runs along the northern section of the
North Fork. County Road 48 is a four-lane
roadway from Mattituck to Southoid and a two-
lane roadway from Southold to Oreenport.
Boisseau Avenue serves a North-South connector

O. DENOGRAPHY
]. Population Characteristics
According to the United States Bureau of the
Census, the Town of Southold experienced
growth of 2,368 persons, or 14.1 percent,
during the 1970-1980 decade. Generally this
growth rate has continued through the
but has now started to slow down because o?
several factors, including cost of land,
availability o{ public utilities, and the
general Ceeling of the Town's elected
officials to control growth, as well as to
preserve open space.
E. CULTURAL RESOURCES
Visual Resources - The visual resources of
this particular project include the
undeveloped wooded areas to the East and the
South of the project area. As the site is
mostly barren, former farm land, with weeds
and wild grasses as a soil cover, in itself is
not considered to have a visual resource.
Historic and Archaeological Resources - Based
upon a review of the literature related to the
archaeology of the North Fork and the NYS
Register of Archaeological 5ires. it is
indicated that no known or recorded aboriginal
sites lie within or adjacent to the parcel
proposed for rezoning. The Incorporated
Chapter New York State Archaeological
Association has confirmed this finding, and it
is anticipated that the proposed action nor
subeequent development of the site will have
impact upon any registered, eligible or
inventoried property. (See Appendix No. 7.>
F. AFFORDABLE HOUSING

"IT' SIGNIFICANT ENVIRONMENTAL
IMPACTS
V. SIGNIFICANT ENVIRONMENTAL IMPACTS
NATURAL RESOURCES
The aspects of the environmental setting that may be
adversely impacted by the proposed actions specifically
include the following:
A. GEOLOGY
Surface - The development o{ this project
which will include construction activities
for residential units, roads, underground
utilities, and such will dis'rupt to a
considerable extent the topsoil
characteristics and existing ground cover,
making erosion more likely during the
development period.
B. WATER RESOURCES
Groundwater - The primary expected impact to
the groundwater from rezoning and development
would be ~rom the nutrients that would enter
the groundwater table via individual leaching
pools and ?rom fertilization of lawns and
other grassed areas. The other possible
impact to groundwater is from buried fuel oil
tanks. Proposed mitigation measures described
in Section VI are such that with the adoption
of them it is anticipated that potential
contamination of recharge groundwater will be
avoided or eliminated.
2 o
Surface Water The installation of paved
streets and the temporary loss of ground cover
during construction will adversely impact the
control of drainage; as well as its patterns
and present channels. Specific mitigation
measures will be necessary to prevent erosion
and to collect and control run-off for
recharge into the aquifer.
Co
AIR RESOURCES
Not Applicable.
0. TERRESTRAL AND AQUATIC ECOLOGY
The rezoning and development of this particular
site will result in a change of vegetation from
present wild grasses and brush to lawns and
shrubbery. As there are no known endangered
species of vegetation, the adverse impact of the
environmental setting is considered cosmetic in
~ature only.
E. AGRICULTURAL RESOURCES
The rezoning and development of this site will
result in the total loss of this acreage to
agriculture. However, even though this area is
considered a good agricultural resource, it has
not been in productive use for five (~) years~ has
not been placed on the Farmland Preservation
Program; nor has it been zoned strictly
agricultural. Therefore, it is determined that
the loss of this area as an agricultural resource
is not the result of this rezoning and
development, but of other unrelated actions.
HUMAN RESOURCES
TRANSPORTATION
Developments of any kind. including residential
development, cannot help but, and will. generate
increased vehicle trips. It is also natural and
understandable that local and adiacent residents
who are used to, like, and enioy the combined low
population urban density, urban and ~yra] area,
feel that any increase in vehicle traffic is an
adverse impact, even though the traffic studies
indicate that the surrounding streets, roads and
inter~ections have adequate capacity for the
projected increaeed vehicle trips without adverse
impact from the increased traffic generated by the
project. (See Appendix No. B.>
LAND USE AND ZONING
There ~ill be a significant change in the land use
and in the zoning. The land use will go from
vacant agricultural to a residential density of
two (2) units per acre, and the zoning will change
from Residential Agricultural
Housing District (AHD). Once
has taken place, it will not be

water supplies many times in excess of the
project requirements. (See Appendix No. 2.)

O. DEMOGRAPHY
Not applicable.
E. CULTURAL RESOURCES
Visual Resources It is generally
considered that a development of any kind that
takes unused open space and changes it to a
residential development causes a loss of
visual resources, and that the proposed action
wil! convert ~7.76Z Acres of open space to
approximately ~4.8 Acres of residential
development. On the other hand. if a well
kept neighborhood of reasonable residential
density, with paved, tree lined streets, well
kept lawns and shrubbery is considered an
improvement to the visual resource, than the
proposed development would not be adversely
impacted. The decision of whether this is an
adverse impact is. obviously, in [he eyes of
the beholder.

F. AFFOROABLE HOUSING
The providing of fifty-five <99) affordable
housing sites, while minimum, as to the Town's
projected needs (10~) is significant as one oS the
Town's first efforts.

MITIGATION MEASURES TO
MINIMIZE ENVIRONMENTAL IMPACT
VI. MITIGATION MEASURES TO MINIMIZE ENVIRONMENTAL IMPACT
NATURAL RESOURCES
The natural items addressed and ?or which mitigation
measures are to be accomplished include:
o Geology
o Water Resources
o Terrestral and Aquatic Ecology
o Agricultural Resources
A. GEOLOGY
All topsoil material is to be stockpiled during
the construction and used {or the restoration and
landscaping around the new housing units. In
addition, every reasonable e??ort will be made to
preserve in place the natural g~owth not only
between housing units but in the designated open
spaces. The open space designated at the drainage
area will be maintained as
its present natural growth

near as possible with
so as to prevent
the construction
period. Additional plantings o? sweetgale.
northern bayberry, native cedar, 3apanese Rose.
and Fugosa Rose are to be planted around the
drainage area. Additional plantings of shrubs and
street trees will also help preserve the top~oil.
Also during the construction period the contractor
will be required to surface the streets as soon as
grading and compacting is complete so as to
preclude erosion in the designated street areas.
B. NATER RESOURCES
]. Ground Water
Mitigation measures to prevent ground water
contamination include the following=
a=
A site construction restriction that
allows no in-ground oil fuel storage
tanks. This action has been previously
supported and publicaly agreed to by
the Southold Town Planning Board.
bo
Historically it has been proven that the
indiscriminate application of lawn
furtilizers can, and will, result in the
contamination of groundwater.
particularly by increased nitrogen
levels. It i~ therefore important that
mitigation measures in the form of
restrictions to limit the application of
such lawn fertilizers in accordance with
practices that will insure the use of
theee nutrients by plant growth and not
allow them to be applied to the extent
that they will percolate into the
groundwater recharge zone. Covenants and
restrictions are being prepared that each
owner and occupant of the housing units
will be required to sign and comply with.
As the proposed development will be utilizing
municipal water supplies, augmented by a new
off-site well, there is no adverse impact to
the sites ground water from over pumping and
salt water upconing. The development will be
expected to use potable available water
resources based on lO0 gallons per capita per
day. Based on the persons per drawing ratio
of ~.~ within the family type residential
units proposed, a year round water use of >~0
gallons per dwelling unit per day is
reasonable, or for a total of fifty-five (~>)
unit~ oF ]8.1~0 gallons per day.
~2
Historically, the collection and direct
discharge of street drainage into surface
waters have been a potential source of water
contamination. Therefore. to eliminate or
reduce this potential surface water
contamination, the majority of the road and
street run-off is being collected and directed
to a natural ponding area, with the
expectation that the percolation process will
provide natural groundwater recharge, and in
doing so improve it quality, both in the
recharge and aquifer, and also as a direct
alternative to discharge to any system that
would drain into the surrounding surface
water, and particularly the Long Creek portion
of Hashamomuck Pond. which has already been
contaminated by direct surface road run-off.

subiect parcel is typical of residential areas and
their immediate periphery. It is expected that
similar populations will be r~tu~ned, by man and
nature, to the development parcel as it matures as
a residential community. A significant mitigation
measure to the terrestrial ecology of the site will
be preservation of open space around the wetlands
and drainage area with maintenance of the original
type ground cover which serves as a Habitat for
animal, bird life, and native type grasses. A 7~
foot buffer strip has been established between the
wetland area and the adiacent housing lots and
will be covenanted to insure its preservation.
~4
E. AGRICULTURAL RESOURCES
There is no known mitigation that is considered to
reduce the impact o~ the agricultural resources. On
this particular site, the land is already out o?
?arm type production and has been since 198~. and
as it has not been zoned strictly agricultural,
placed in the Farmland Preservation Program, nor is
being presently used for agriculture by the Owner,
and there?ore there is no indicated attempt o~
returning it to agricultural production. It
should be realized, however, by all planners and
reviewers that once an agricultural resource is
changed ?rom ?armland to residential, then it is
?orever lost ~or the ~gricultural use.
HUMAN RESOURCES
The human resources addressed for which mitigation measures
are to be accomplished include:
o Transportation
o Land Use and Zoning
o Community Services
o Cultural Resources.
TRANSPORTATION
The proposed project will not create significant
adverse impact on traffic conditions within or
along the major routes serving SouthoJd.
specifically County Road 48 and Route 2~ (See
Appendix No. 8> and can readily accommodate the
additional traffic flow generated. A project specific
traffic analysis has been accomplished, the
summary of which states:
"After completing the
evaluation of each of
intersections, it was
impact analysis and
the study
determined that there
will not be any adverse impact to area roads
from fraffic generated from the proposed
Affordable Housing Proiect."
The detailed traffic study is contained in Appendix
No. 8.
~6
Even though the proposed rezone and development
project will not create a significant adverse
impact on traffic conditions as per the enclosed
traffic study <See Appendix No. 8> it is planned
to provide additional methods of ingress and
egress from the site to adjacent property to
connect in the future with State Route 25 via
Tuthill Road Extension.
B. LAND USE AND ZONING
There is very little mitigation measures that can
be taken when you are changing a land use from
agricultural to ~esidential, and the change of
zoning from Agricultural/Residential to higher
density residential. The most logic'al and
practical measure is to develop a parcel to be
consistent with the ~eeidential character of the
adjacent property to the West and North. and also
to lay out the proposed development which will
permit the installation of suitable residential
infrastructure, which includes municipal water and
properly developed local streets that will provide
a well planned residential type environment.
Included in this would be the landscaping and
plantings, especially street trees, and other
related type of landscaping that would transform
the developed site into a pleasing visual impact.
57
C. COMMUNITY SERVICES
8. Public Water Supply
As indicated in Section V. the Village of
Greenport has available to them an estimated
~.0 million gallons of water per day and are
in the process of increasing this capacity by
1.0 to 2.0 million gallons per day. This
project will require ]B,]~O gallons average
per day, or only approximately 0.9~ to 1.8~
the projected available production of the
additional water supply to be made available
in the near future.
To preserve the present good quality of the
on-site water and prevent contamination by
nitrates, part of the mitigating action is to
require all new owners to limit their lawn
fertilizer application, have septic tanks
pumped as recommended by the Suffolk County
Department of Health Service on a periodic
basis. These proposed mitigated type actions
will provide further preventive type action to
surrounding groundwater aquifers.
As it has been determined that the proposed
rezonin~ and development will not provide any
adverse impact to Community Services. no
mitigation action Cot these are required.

CULTURAL RESOURCES
1. Visual Resources
The only mitigation measure considered worthy
of consideration is to arrange the street
tree and shrub plantings such that they will
enhance the visual impact of the adiacent
neighborhoods.
2. Noise
To avoid disturbances to the surrounding
residences site construction will be limited
to normal daylight working hours. Included
in the site plans are shrubs and landscaping
that will reduce noise transmission from the
project site.

ALTERNATIVES
VIII. ALTERNATIVES
A. ALTERNATIVE DESIGN AND TECHNOLOGIES
I. Site Layout
Unless one considers an alternative to a
dif{erent deneity than that ie propoeed to
rezoning to AMD, then there is a limited
amount of alternative site layouts that could
be accomplished. Clustering by reducing lot
sizes to approximately 10,O00 square feet was
considered but felt the proposed layout was
more in keeping with the surrounding
development. It was determined that this
type of alternate site layouts would
generally have a more significant
environmental impact, especially visual, then
would result from alternative layout.
2. Orientation
So as to prevent a degree a sameness and to
promote individual characterizations of the
individual residences, the developer plans to
have the new owners position and locate
residential house units on their respective
lots with varying degrees of differences in
position and setback requirements. Also, the
shape o~ these affordable housing lots has
also been varied to prevent this same
potential degree o~ sameness.
The site layout and orientation has already
taken maximum advantage of the site slopes and
natural drainage so as to preserve and enhance
both o~ these.
B. ALTERNATIVE SITES
Not applicable~
C. ALTERNATIVE SIZE
There is no reasonable alternative to increasing
or decreasing the proposed development o~ this
site ~or the proposed use of ~?ordable housing.
Increasing the lot size would increase the cost of
such lots, and immediately result in a price
increase above the a~ford~ble housing maximum cost
as set by the Town of Southold.
Decreasing the lot size would necessitate
compliance with Health Department regulations
regarding community water and sewer systemm.
The most practical method in accomplishing this
would be to install a package type sewage
treatment plant similar to that recently installed
for the Shelter Island Heights Property Owners
Corporation. A treatment plant at this location
would, however, require an on-site recharge system
and involve both Suffolk County Department of
Health Services and New York State Department of
Environmental Conservation approvals. With the
above in mind, it doee not appear economically
feasible to pursue this alternative at this time.
This increased density also would not be in
character with the surrounding residential character.
It has already been established by the number of
applicants that wish to be considered for the
residential units in this Affordable Housing
District, that there already exists a market
demand, and community needs in excess of what is
proposed.
Another alternative would be to cluster sixteen
<16) housing lots of one (l> acre each, which
could be accomplished within the present zoning.
This is the most likely alternative as a change of

There are no known ~acts at the present that
suggest that alternative scheduling, for example a
delay in action on the requested rezoning, or the
subsequent development of the parcel, would in any
way provide for additional mitigation of any
environmental impacts foreseen. It is anticipated
that the construction on the individual affordable
housing lots will be at the schedule and
discretion of the new Owners.
E. ALTERNATIVE LAND USE
The proposed site of the
Development is suitable
include the following;
Affordable Housing
for a variety of uses to
o
0
0
Agriculture
Commerical or industrial facilities
Other types of housing with varying degrees
of density.
This site was formerly farmland, and with clearing
could be returned to this use. An informal check
o~ local residents has indicated that this area
has not been farmed for over five (~> years.
Returning this to agricultural production, with
the increased use of fertilizer, etc., has a
potential of contaminating the groundwater with
nutrients such as nitrogen.
Because o4 the residentia] nature of the
surrounding area, the use of this site for
commerical and industrial activities is not felt
to be appropriate. It would be expected to meet
with local resistance and not be considered
favorable by the Southold Town Planning Board.
F. NO ACTION
The no action alternative examined in this
instance would be for the Town Board's rejection
of the Change of Zone and the Planning Board's
failure to approve this site for affordable
housing units. It is believed that much a failure
to accomplish this frustrates the efforts Of the
Owner. D.B,M. Company. to undertake the
development of this particular site to include
affordable housing lots that will assist in
helping fill the ex/sting demand for Moderate
Income housing. The end result to this no action
alternative it would be expected that the
applicant would withdraw his request for rezone
and the property would continue to be in the two
(2) Acre zoning.
This would mean that the plans for affordable
housing would be discontinued for this particular
site. As previously discussed, there are no
significant environmental impacts pertaining to
this proposed action that would be avoided if the
Town Board and the Town Planning Board were to
pursue the no action alternative.

X. GROWTH INDUCING ASPECTS
A. POPULATION
This development of moderate income housing is
expected to result in a resident population of
approximately one hundred ninety ()90) people.
This cannot be directly converted, however, into
increased population as it is expected that the
maiority oF the occupants will be young working
families that will relocate from sub-standard or
illegal rentals in other parts of the Town. With
practically no affordable housing within the Town.
these young working families, out of economic
necessity, have had to live with a catch can
situation of available housing space, which also
includes living with parents on a interim basis.
until other means of housing could be obtained.
Most often the concerns or a development is
increased population and its impact on local
schools. As explained above, there is very little
school population increase expected, except some
that wil! be expected to occur in the Southold
school district because of the location of this
particular project. Even in this situation.
however, a small increase in school age population
may be considered a plus because of the decline in
school population (except for the last two years>.
Reference is made to Appendix No. 6. A small
increase in the school population should result in
a better ratio of expense per pupil than now
exists.
B. SUPPORT FACILITIES
It has been determined that existing businesses
within the Town are sufficient to serve the new
housing units. An increase in support businesses
often comes about from significant increase in
population, but as pointed out in A above, this is
not likely to occur as a result of this particular
project.
Probably the most noticeable increase in service
type work will be maintenance, including snow
removal of the additional roads and streets within
the housing area. The most direct impact on this
would be felt by the Southold Town Highway
Department.
7O
C. DEVELOPMENT POTENTIAL
The project in itsel{ is not expected to result in
any increased deveJopment potential, mainly
because o{ its sel{-contained nature. Because of
the urgent need {or moderate income housing of
greater numbers than will be suppIied by this
project, the success of this one is expected to
give encouragement of seve~a! others to meet the
areas requirements.
EFFECTS ON THE USE &
CONSERVATION OF ENERGY
RESOURCES
XI. EFFECTS ON THE USE AND CONSERVATION OF ENERGY RESOURCES
PROPOSED ENERGY SOUTCES AND ALTERNATIVES
Not Applicable.
B. ANTICIPATED SHORT-TERM/LONG-TERM LEVELS OF ENERGY
CONSUMPTION
Not Applicable.
C. INDIRECT EFFECTS ON ENERGY CONSUMPTION
It is not anticipated that there will be any
significant indirect effects on energy
consumption. The project does not have an impact
on public transportation methods, and the
increased levels of traffic to the proposed
project would be expected to occur at another site
if this project was not approved and brought to
fruition.
D. ENERGY CONSERVATION MEASURES
The affordable housing units will be constructed
in strict accordance with the current New York
State Energy Conservation Construction Code.

Appendix A
State Envlronmentel Quality Review
FULL ENVIRONMENTAL ASSESSMENT FORM
Purpose: The full EAF is designed to help applicants and agencies determine, in an orderly manner, whether a project
or action may be significant The question of whether an action may be significant is not always easy to answer. Frequent-
IV. there are aspects of a project that are subiective or unmeasureable. It is also understood that those who determine
significance ma,,, have little or no formal knowledge of the environment or mav be technically expert in environmental
analysis In addition, many who have knowledge in one particular area may not be aware of the broader concerns affecting
- the question of-significance
The full EAF is intended to provide a method whereby applicants and agencies can be assured that the determination
process has been orderly, comprehensive in nature, yet flexible to allow introduction of information to fit a project or action.
Full EAF Components: The full EAF is comprised of three parts:
Part 1: Provides objective data and information about a given project and its site. By identifying basic project
data. it assists a reviewer in the analysis that takes place in Parts 2 and 3.
Part :2: Focuses on identifying the range of possible impacts that may occur from a project or action. It provides
· ' ' guidance as to whether an impact is likely to be considered small to moderate or whether it is a potentially-
large impact. The form also identifies whether an impact can be mitigated or reduced.
Part 3: If anv impact in Part 2 is id~ntifi,,d a~ petentic.~¥-Ia*l~:e, t. hen Part 3 is used to evaluate whether or not the
impact is actually important
DETERMINATION OF SIGNIFICANCE--Type I and Unlisted Actions
Identify the Portions of EAF completed for this project: i'-1 Part 1 [~ Part 2 i'~Part 3
Upon review of the information recorded on this EAF IParts 1 and 2 and 3 if appropriate], and any other supporting
information, and considering both the magitude and importance of each impact, it is reasonably determined by the
lead agency' that:
Fi A The project will ,or result in any large and important impacffs) and. therefore., is one which will not
have a significant impact on the environment, therefore a negative declaration will be ~prepared.
B Although the project could have a significant effect on the environment, there will not be a significant
effect for this Unlisted Action because the mitigation measures described in PART 3 have been required.
therefore a CONDITIONED negative declaralion will be prepared.'
~3 C The project may result in one or more large and important impacts that may have a significant impact
on Iht. enwroflment therefore a poslti~,e declaration ,'ill be prepared.

General Information (Read Carefully)
· In completing the form the reviewer should be guided by the question: Have my responses and determinations been
rea~onablef The reviewer is not expected to be an expert environmental analyst.
· Identifying that an impact will be potentially large (column 2) does not mean that it is also necessarily silnificant.
Any large impact must be evaluated in PART 3 to determine significance. Identify/n8 an impact in column 2 simply
asks that it be looked at further.
· The Examples provided are to assist the reviewer by showing types of impacts and wherever possible the threshold of
magnitude that would trigger a response in column 2. The examples are generally applicable throughout the State and
for most situations. But, for any specific project or site other examples and/or lower thresholds may be appropriate
for a Potential Large Impact response, thus requiring evaluation in Part 3.
· The impacts of each project, on each site. in each locality, will vary. Therefore. the examples are illustrative and
have been offered as guidance. They do not constitute an exhaustive list of impacts and thresholds to answer each question.
· The number of examples per question does not indicate the importance of each question.
· In identifying impacts, consider long term, short term and cumlative effects.
Inslructlons (Read carefully}
a. Answer each of the 19 questions in PART 2. Answer Yes if there will be any impact.
b. Maybe answers should be considered as Yes answers.
c. If answer/n8 Yes to a question then check the appropriate box (column I or 2) to indicate the potential size of the
impact. If impact threshold equals or exceeds any example provided, check column 7. If impact will occur but threshold
is lower than example, check column 1, ,.
d. If reviewer has doubt about size of the impact then consider the impact as potentially large and proceed to PART 3.
e. If a potentially larse impact checked in column 2 can be mitigated by change(s) in the project to a small to moderate
impact, also check the Yes box in column 3. A No response indicates that such a reduction is not possible. This
must be explained in Part 3.

Part III
D.B.M. Change of Zone
Impact on Water
The proposal may have an impact on groundwater since it requires
a source of water that does not have approval to serve the
proposed action. Unless the Village of Greenport grants
approval for water hook-up, the proposed action will allow
residential uses in an area without water and sewer services.
If the Village will require a well on site, its zone of
concentration will be impacted by half acre lots. However,
should public water serve the proposed development, no
significant impact on groundwater is anticipated. Approval by
Suffolk County Department of Health Services and by the Village
of Greenport of connection to the Greenport Water Supply System
should precede approval of the subdiv&sion by the Southold
Planning Board. The drainage plan must also be approved by the
Planning Board and Superintendent of Highways.
Impact on AGricultural Land Resources
The proposed action will affect agricultural and land resources
since it will irreversibly covert more than 10 acres of
agricultural land.
Impact on Transportation
There will be a moderate impact to transportation since there
will be increased traffic with 55 dwelling units.
Impact on Energy
The proposed action will require the extension of an energy
supply system to serve more than 50 single family residences.
Impact on Air
During construction, adverse air quality impacts are possible.
The use of standard dust control and vehicular emissions control
measures will eliminate air quality impacts. Dust control
measures shall be approved by the Planning Board.
Noise Impacts
During construction, adverse noise impacts are possible.
Scheduling construction during normal working hours and
buffering existing dwellings with landscaping and earth berms
will mitigate against any significant adverse impacts.
Impact on Growth and Character of Community or Neighborhood
The proposed action will cause a change in the density of land
use. The proposal will also create a demand for additional
community services as well as set an important precedent for
future projects. The proposed action would have a small impact
on the community's goals, however, it does fit in with the
criteria of the adopted affordable housing district.
Archaeological Impacts
Assessment by a competent authority is required.
Rare, Threatened or Endangered Species Impacts
Assessment by a competent authority is required.

PLANNING BOARD
A scoping session was held on Wednesday, July 13, 1988 at ll:S~
a.m. at the Southold Town Hall to discuss the topics to be
included in the Draft Environmental Impact Statement (DEIS) for
the D.B.M. change of zone application.
Present were: Planning Consultant, David Emilita of SAI, Planner
Diane M. Schultze, of SAI, Councilwoman Jean Cochran,
Councilwoman Ellen Larsen, Councilwoman Ruth Oliva, Consultant
for applicant Merlon E. Wiggin, Applicants Richard Isreal and
Herbert Mandell, Attorney for the applicants William Moore,
Planner Melissa Spiro, Town Planner Valerie Scopaz, and Community
Development Officer James McMahon.
It was noted that the attorney for the applicants had prepared a
preliminary scoping checklist. Mr. Emilita used this checklist
as a basis for the topics to be included and also detailed
additional items. The items in the scoping checklist attached,
as well as those that follow are to be included in the DEIS for
this proposal.

F. Approvals
This section must include a listing of all approvals
necessary for the proposal.
IV. Environmental Setting
A. Geology
Surface - USSCS specifications are acceptable for this
section.
Topography - Drainage surface flow direction is to be
included in this section.
B. Water Resources
Groundwater - The groundwater flow is important to include
due to the well on site and to obtain a determination of what is
feeding the well site. It was agreed that borings could be done
to determine static well levels.
Surface Water - It was noted that there is no need to
describe surface water.
D. Terrestrial and Aquatic Ecology
1. Vegetation - There is concern about the vegetation in and
near the wetland and a listing of any threatened or endangered
plant species must be included.
2. Fish and Wildlife - A listing of any threatened or
endangered animal species in and near the wetland must also be
included.
3. Wetland - It was noted that the Planning Board had asked
the applicant to redesign the layout so the lots would not impact
the wetland on the site. It was also noted that there are
wetlands which abut the site on the adjoining property. Any
impact to this wetland area must also be included.
A. Transportation
A traffic study must be conducted indicating the existing and
projected traffic on Boisseau Avenue and Yennecott Drive. The
turning movements in the intersection of Boisseau, Yennecott and
County Route 48 must also be included.
SZEPATOWSKI ASSOCIATE5 INC. ENVIRONMENTAl CONSULYANTS & PIANN[~S
B. Land Use and Zoning
This section should include the land use plan and show how
this proposal implements the Master Plan.
C. Community Services
Ail community services noted in the scoping checklist are to
be addressed. Since there are no recreation facilities on the
site, recreation facilities in the vicinity of the site which
would be available to the residents of this proposal must be
included. These recreation facilities should be within walking
distance or a short driving distance. It was also noted that the
proposed well site cannot be used as both a well site and a
recreation area.
D. Demography
This discussion should focus on the Southold Hamlet.
E. Cultural Resources
This should include a description of the general visual
character of the proposal. With regard to historic or
archaeological resources, if there is a potential then the
proposal can be redesigned or a dig can be conducted at the time
of construction. This assessment must be made by a competent
authority.
V. Significant Environmental Impacts
This section must include a discussion of the water supply
system. It was noted that to date there are no permits for the
well site proposed. A detailed analysis of the recharge within
the zone of concentration, using the Cornell Study is to be
included in the document. A locus map for existing publio wells
in the area of the site is also requested since measures may need
to be taken to insure that the well proposed for the site doesn't
impact any existing wells. It was also noted that the Village of
Greenport well number 63 is not far from this site and they draw
salt.

VIII. Alternatives
The following alternatives are to be discussed:
- A subdivision with the existing zoning. It was noted that
a 16 one-acre lot cluster subdivision is currently pending before
the Planning Board.
- No Action
- Alternative sites - This discussion will show why this is a
good site for the proposal and how it implements the Master Plan.
-Alternative size
ntroduction
The following checklist of topics is intended
as a starting point for developing a detailed scope
for a project-specific Draft Environmental Impact
Statement, Typically. no one project will require a
discussion of all the topic areas contained in this
document. Through the scoping process, this list of
topics should be refined to reflect issues unique to
the proposed project. Topic areas may be deleted,
added, or elaborated upon, to arrive at the final
scopJng document.
The purpose of the checklist format is to
identify the basic topic areas for the Draft ElS. This
is accomplished by reviewing the list and placing a
check in the box located to the left of those topics
which should be discussed. The model scoping
checklist can also be used as a worksheet, including
comments, suggestions and identification of the
particular example(s) that are relevant to a detailed
discussion of the topic or issue that has been check-
ed. Conversely, those topics which are not checked,
are issues not associated with the project, and may
be eliminated from discussion in the Draft ElS.
Minimum requirements for any Draft ElS are
already checked for convenience.
The next step is to expand the list to include
or elaborate on'those topics unique to the proposed
project. A blank sheet is included at the end of the
checklist for such additional iniormation.
The scoping process involves several steps in
addition to compiling a list of topics. Scoping also
includes discussions on the quantity and quality of
information required and the methods for obtaining
that data.
NOTE: This checklist was designed t9 be
used in conjunction with the section on scoping con-
rained in the SEQR Guideline-Dralt and Final EIS's.
It is also important to emphasize that this checklist
should serve only as a model to assist in the scoping
of a Draft ElS. It should not be used as a substitute
for actively scoping a Draft ElS for a specific pro-
ject.
(~over Sheet
All EIS's (Draft or Final) shall begin with a cover
sheet that indicates:
A. Whether it is a draft or final statement
B. Hame or other descriptive title of the project
C. 'Location (county and town, village or city) of

APPENDIX '~2
WATER
PRO3ECT WATER REQUIREMENTS AND PROPOSED SOLUTION TO
NEET THESE REQUIREMENTS
GENERAL
Insuring that potable water is available for this affordable
housing project, and the methodology to insure same, is one
of the primary problems that needs to be resolved in order
to make this affordable housing project a viable one. It is
also a problem that has had the detailed attention of not
only the developers, but Town and Village officials. A
~eview of this problem aeea includes the following
assumptions of fact=
CONNECTION TO PUBLIC WATER'SUPPLY IS REQUIRED - To have
the proiects, affordable density must be increased to
the point where Health Department requirements will
include a public water supply. Difficulties in
obtaining approval, constructing, operating, and
maintaining a site specific water supply are very
difficult and economically impractical.
CONNECTION TO THE VILLAGE OF GREENPORT°S SYSTEM IS THE
ONLY LOGICAL SOLUTION AT PRESENT - Greenport presently
has public water mains along road rights-of-way, both
to the North and South of the proiect site. Also. the
site is totally within the Village of Greenport
Franchise area For municipal water.
GREENPORT TEMPORARILY IS NOT IN A POSITION AT PRESENT
TO SUPPLY WATER TO THIS PRO3ECT - Greenport is under
mandate by various regulatory agencies to improve both
their quality and quantity of available water supply
before new projects of this type can be connected.
.4.
IMPROVEMENTS TO GREENPORT'S SYSTEM, AND ESPECIALLY
INCREASED PUMPING CAPABILITY. MUST OCCUR OR ASSURANCES
THAT THEY WILL OCCUR BEFORE AFFORDABLE HOUSING PRO3ECTS
CAN BE APPROVED - The Village of Greenport is doing
specific planning and initiating actions for adding to
their water supply capability. These include the
identification and potential purchase of new well sites
as well as initiating a bond act to raise monies for
the development of hook-up of new well systems. Funds
have also been identified and voted on to improve water
quality at problem wells.
THE AVERAGE DAILY WATER REGUIRE~ENTS FOR THIS AFFORDABLE
HOUSING PROgECT IS 18,1~0 GALLONS PER DAY -
multiplier o~ 2.5, the peak requirement ~or
site would be 4~,570 gallons per day.
Using a
the project
SOLUTION:
Considerable effort and discuesion went into the developing
of the beet and most viable solution to supply water to this
affordable housing proiect. 0~ the poeeible ~cenarios four
<4> were explored in detail and include the following:
DEVELOP AN ON-SITE WELL THAT WOULD ONLY SUPPLY THIS
PARTICULAR PRO3ECT. The expectation o{ approval ~rom
the Suffolk County Department of Health Services
becauee o{ the proximity o~ municipal mains was highly
unlikely. It would aleo mean that the developer would
be placed in a position to. not only develop this well.
but operate it as well. requiring the hiring of
liceneed and trained operating personnel.
DEVELOP THE ON-SITE WELL AND TURN IT OVER TO THE
VILLAGE OF GREENPORT. This approach has considerable
merit, especially seeing that it would move this
project near the head of the list, based on the present
Village of Greenport policies of water hook-ups.
Because of the project location, this well would be
considered a limited production one. and as the costs
for developing a limited production well are equal to
that of developing a full production well. this
solution has its drawbacks.
THE DEVELOPER, EITHER ON HIS OWN. OR IN CONJUNCTION
WITH OTHER DEVELOPERS, OBTAIN OR LEASE A WELL SITE.
obtain the necessary approvals, and install a well
complete with pump station, controls, and emergency
support systems as required for a turn-key operation.
after which it would be turned over to the Village of
Greenport. Seeing that this is an affordable housing
proiect, from an economic point of view it was not
rational to develop a 400,000 to ~00,00 thousand
gallons per day well when this project only required
]8,000 gallons per day. Actively pursuing this route
could also be contrary to the overall Village's plans
for their own courses of action in developing new full
production wells.
HOOK UP TO THE VILLAGE OF GREENPORT'S MUNICIPAL SYSTEM.
The project site is totally within the Village of
Greenport's water franchise area and, from both a
logical and legal point of

Discussions with Village officials indicate that they
are actively pursuing increased production capability
as well as improvement in water quality, including the
initiation of bonds for requi~ed funding. Therefore.
it is considered that the only logical course of action
is to stay on the Village's list of those requesting
connection, and have the project ready for hook-up as
soon ss water service is available.

to the best of my knowledge there is no record of Indian
camp sites or burial grounds in that area.
Because aboriginal people lived here for over 9,000
years, no one can tell what might lie beneath the surface
without excavating. There most certainly would be scattered
artifacts anywhere on undeveloped property on Long Island.
Even test hole digging isn't positive proof, as Shoreham
was built on the site of what I believe to be the largest
concentration of aboriginal habitation on Long Island.
Sincerely,
Past President

Most of the subject parcel is an "old field" except for
a corner of freshwater wetlands on the east side and a
grove of locust trees on the southeast.
In addition to the many grasses which dominate includ-
ing some or all of the following: fox tail, Setaria,
spp.; bluestem, Andropogon, spp.; panic grass, Panicum,
spp.; Muhlenbergia, spp.; rye grass, Lolium, spp.; quack
grass, Agropyron, s_~.; Triodia, spp.; fescue, Festuca,
spp.; several shrubs and vines are appearing. Blackberry,
Rubus allegheniensis is found on the borders of some of
the old farm roads.
Scattered throughout the fields are bayberry, Myrica
penns¥1vanica; groundsel bush, Baccharis halimifolia;
red cedar, Juniperus virginiana.
Wildflowers, especially white heath aster, Aster ericoides;
goldenrod, Solidago, spp.; blazing star, Liatris, spp.;
teasel, Dipsacus sylvestris; ragweed, Ambrosia artemisii-
folia; cocklebur, Xanthium strumarium; tansy, Tanacetum
vulgare; yarrow, Achillea millefolium; burdock, Arctium
minus; dandelion, Taraxacum officinale; are also abundant.
The type of habitat is characterized by fields which have
until recently (5~ years) undergone cultivation but which
- 2 -
are now being re-colonized by native species. These
"soft-stem" species are the primary invaders in a long
succession which ultimately leads to a climax forest.
The many grain species of grasses, plus the dense nature
of the cover, make old fields excellent habitat for
small mammals (especially rodents) and birds. Produc-
tivity is high especially where soil types are (or were)
condusive to agriculture.
Locust trees, Robinia pseudoacacia occur in a grove toward
the southeast side of the parcel.
As shown on the survey, freshwater wetlands extend just
over the corner of the subject parcel and continue east-
ward. The wetlands are lower in elevation than the ad-
jacent fields and are extremely heavily overgrown. Some
of the vines found here which make entry difficult are:
foxgrape, Vitus labrusca, bittersweet, Celastrus scandens;
blackberry, Rubus allegheniensis; greenbrier, Smilax rotundi-
folia. Trees found in or on the border of the wetlands are
locust; oak, Quercus, spp.; red maple, Acer rubrum; sumac,
Rhu$ typhina, and others.
The various habitats will attract typical fauna adapted
to each (with some overlap).
- 3 -
Birds
commonly associated with fields or old fields are:
Killdeer, Charadrius vociferus
Mourning dove, Zenaidura macroura
Barn swallow, Hirundo rustica
Red-wing blackbird; Agelaius phoeniceus
Common grackle, Quisculus quiscula
Song sparrow, Melospiza melodia
Bobwhite, Colinus virginianus
House wren, Troglodytes aedon
Common yellowthroat, Geothlypis trichas
American goldfinch, Spinus tristis
Common crow, Corvus brachyrhynchos
Northern mockingbird, Mimus polyglottos
The red-tailed hawk, Buteo jamaicensis, observed on another
old field approximately 1 mile away, was not observed here
but is likely to frequent the area to hunt. The hawk is
a New York State "threatened species."
Birds likely to inhabit the wooded area and its border
with the fields are:
Bobwhite, Colinus virginianus
Yellow-billed cuckoo, Coccyzus americanus
Common flicker, Colaptes auratus
Hairy woodpecker, Picoides villosus
Eastern wood peewee, Contopus virens
Blue Jay, Cyanocitta cristata
Common crow, Corvus brachyrhynchos
Black-capped chickadee, Parus atricapillas
Tufted titmouse, Parus bicolor
White-breasted nuthatch, Sitta carolinensis
Northern mockingbird (forest edge only), Mimus
polyglottos
Gray catbir~ Dumetella carolinensis
European starling (forest edge only), Sturnus
vulgaris
Red-winged blackbird, Agelaius phoeniceus
Common grackle, Qui$culus quiscula
Northern (Baltimore) oriole, Icturus galbula
Cardinal, Richmondena cardinalus
Mammals associated with open or old field habitat ~include:
White-footed mouse, Peromyscus leucopus
Meadow vole, Microtus pennsylvanicus
Meadow mouse, Microtus ohrotorrhinus
House Mouse, Mus mu$culus
Norwegian brown rat, Rattus norvegicus
Cottontail rabbit, Sylvilagus floridanus
The white-tailed deer, Odocoileus virginianus may traverse
the site in search of food.
As previously stated, the small mammal population is an im-
portant source of food to such predators as the hawks and
red fox, Vulpes fulva, should any be present. The rodents
also cause damage to crops, gardens, and structures and
must be controlled in some fashion.
Just inside the wetlands delineated on the survey, a
garter snake, Thamnophis siritalis was observed sunning
itself on a branch. Turtles (especially the box turtle,
Terrapene carolina), salamanders, toads, and frogs may
also be present in and near the wetlands. Other snakes
including ribbon, hog nose, and black racer may be present.
The woods are probably inhabited by small mammals other
than those listed for the fields. These include voles,
chipmunk, opossum, raccoon, and possibly deer and fox.
Feral cats are also possible.
- 5 -
The primary value of the wetland, in my opinion, is as
cover and a good source for wildlife; and to recharge
freshwater into the ground. The portion on the subject
parcel is a "seasonal wet woods." Beyond, it was re-
ported by the surveyors that open water is present
although this was not personally observed due to the
denseness of surrounding vegetation.
Wetlands should be preserved due to the myriad functions
they exhibit. Adequate setback from them before any
construction occurs will ensure their continued con-
tribution to the ecosystem.
Development of the fields will drastically alter the
habitat and fauna associated with it. Some species of
birds and mammals are able to adapt while the shyer
species will be displaced or eliminated if no similar
habitat capable of absorbing them exists.

The following demo~apbies were' taken from the 161 qualified applications
received for the Southold Town Affordable HousingProg~am lottery. In
388 requests for application were received, and of that n,--her, 210 were
completed and returned in some form. The 210 were reviewed for compliance
with the Southold Town Affordable Houaing Law, and 49 (23.35) were found
ineligible due to residency, employment or financial problems.
Qualified Ap~licant Information:
Of the qualified applicants, the vast majority were under ~0 years of age
(93.1%). Geners~]y spea~, the applicant was in their late twenties to
early thirties.
Employment:
The applicants are represented by tradespeople i.e., carpenters, truck
drivers, pi,--hers, and professlo~l people i.e., school teachers, bank · :.:
employees, newspaper workers etc.
F~m{ly Size and Composition:
There are ~]mnst 10% of the applicants that are sir~e parent h~d of the
household. Al~nost 51~ are nuclear units with one or more ch{~dren,
though 19.~% of the q, ml~fied applicants were single individuals (many
of whom are contemplatins marriage).
Financing Assistance:
Many of the families involved can easily afford to m~intain the mortsa~e
and carry/nE charges of the home, but not the down-payment and closing
costs. F~m~l~es, and, in :some case~, even employers, have volenteered to
provide the necessary fundins:, to inst~'e that the families would be able
to remm~_n in the area.
Qualified participants generm11¥ fell within the program's targeted group
of $25,000 - $42,000 combined f~m~ly income. The applicant~ are generally
upwardly mobile, so that even the m~rgi{'~lly qualified families can be
reasonably expected to see income figures improve within the foreseeable
future.

Dear Mr. Wiggin:
I am in receipt of your letter dated August 31,1988 wherein you ask
for an impact statement relative to the erection of fifty-five (55) single
family homes in a new developement east of Boisseau Avenue.
There are many factors to be considered. How many people will be living
in each home? How many of these people will be operating motor vehicles?
Will there be many elderly people who might require additional services?
All of these questions at this point in time are unknown so my assessment
will not be 100% accurate. If there are an average of three (3) people per
home making a total of 165 inhabitants of the community I cannot imagine
that the Southold Town Police Department would not be able to properly
serve the people if our present staffing does not decrease.
If you have any further questions please do not hesitate to contact
me.

Dear Dr. Wiggins:
Pursuant to your letter of 2 November 1988, Cashin Associates, P.C.
(CA) is pleased to present this proposal for the traffic study
portion of a Draft Environmental Impact Statement (DEIS) related
to a fifty-five (55) single family unit affordable housing project
proposed in the Town of Southold.
We have reviewed the study requirements contained in your letter
and supporting documents. Moreover, we have discussed the project
with the concerned agencies and have determined that the following
tasks are required for a study that the Town of Southold, the
Suffolk County Department of Public Works (SCDPW), and the New York
State Department of Transportation (NYSDOT) would find acceptable:
Data

Road
Collection - This task will involve gathering traffic
for the Main Street (SR 25), Boisseau Avenue and Middle
(CR 48). These data will include:
CA will obtain available machine traffic volume counts
from the SCDPW for Middle Road (CR 48) and the NYSDOT for
Main Street (SR 25).
CA will conduct a bi-directional machine count on
Boisseau Avenue between Main Street (SR 25) and Middle
Road (CR 48).
CA will conduct turning movement counts for the impacted
intersections for the eight highest hours of an average
day. Turning movement counts will be conducted for a
weekday between the hours of 7:00 a.m. to 11:00 a.m. and
2:00 p.m. to 6:00 p.m. These counts will be conducted at
Main Street (SR 25) at Boisseau Avenue and Hobart Avenue
and Middle Road (CR 48) at Boisseau Avenue and Yennecott
Drive.

CA will obtain traffic accident data from the NYSDOT and
SCDPW for the most recent three (3) year period for the
two intersections where turning movement counts are to
be conducted.
CA will collect data necessary for the evaluation of
existing traffic control devices and sight distance
at proposed development driveways.
e
Traffic Impact ;tnalysis Using the existing data and
the data developed during the analysis, CA will prepare
trip generation, distribution, assignment and operation
analyses of the existing and future traffic on the
roadways identified above. As part of the operation
phase analysis, CA will develop information on the
operating characteristics of each intersection and
roadway link for any existing, no-build and build
conditions.
e
Mitigation - Based on the information generated in'the
previous task, CA will develop conceptual designs as
required, for the necessary improvements and mitigation
scenarios.
Report - CA will prepare a report sua~marizing the data
collection, analytical and mitigation phases of the study
in a format that is acceptable to the Town of Southold.
CA will perform the above services for a fixed fee of $ 6,500.
Included in this fee is the cost of reproducing 10 copies of the
document, but does not include the cost of the personnel who will
actually perform the turning movement counts. It is our
understanding you will supply those individuals. Our fee does
however, include the cost of equipping and training them for this
assignment.
If you find this proffer satisfactory, please sign at the location
provided below and return an executed copy of the proposal to the
undersigned with a retainer in the amount of $ 2,000. The remainder
of our fee will be due upon delivery of the final document. A
duplicate copy of this proposal is provided herewith for your

EXECUTIVE SUMMARY
The D.B.M. Company - Affordable Housing Project
This traffic impact study has been developed as part of a Draft
Environmental Impact Statement (DEIS) and is in support of a
change of zone application for the construction of the D.B.M.
Company/Affordable Housing Project. The D.B.M. Company/
Affordable Housing Project is a planned residential complex of 55
single family homes to be constructed on a 37 acre site in the
Town of Southold, Suffolk County, New York, (See Figure 1). The
site, which is currently Zoned A-residential/agricultural, will
require a change of zone from the existing zoning designation to
the affordable housing district AHD residence designation.
The site is
located on
Road (CR 48)
presently a partially wooded, undeveloped parcel
the southeast corner of the intersection of Middle
at Boisseau Avenue and Yennecott Drive.
A traffic impact study is required as part of the DEIS for the
D.B.M. Company/Affordable Housing Project in accordance with the
Article 8 of the Environmental Conservation Law. This document
is submitted for compliance with the New York State Environmental
Quality Review Act (SEQRA). The purpose of the traffic impact
study is to research and analyze the potential environmental

The capacity analysis evaluation of each study location revealed
that the Level of Service (LOS) and Volume to Capacity ratios
(V/C) remained within acceptable ranges with the addition of the
development traffic added to area road traffic. The anticipated
trip generations from the site are well within the capacity of
the area road system to accept the demand. The maximum trips to
be generated in any one direction on Boisseau Avenue will not
exceed 32 vehicles per hour, or one vehicle approximately every
two minutes. The maximum trips to be generated in any one
direction on Yennecott Drive will not exceed 4 vehicles per hour,
or one very vehicle every 15 minutes.

After completing the impact analysis and evaluation of each of
the study intersections, it was determined that there will be no
adverse impact to the area roads from traffic generated by the
proposed Affordable Housing Project.

as part of an overall DEIS. The report summarizes an evaluation
of the existing area traffic, the projection of existing traffic
to the build year 1990, and its combination with the traffic that
would be generated by the proposed development. The analyses and
evaluations in this report are based on vehicle traffic counts,
field investigations, and data gathered from various agencies
including the New York State department of Transportation
(NYSDOT) and the Suffolk County Department of Public Works
(SCDPW).

SECTION II
EXISTING CONDITIONS
A. Site Study Area
The proposed D.B.M. Company/Affordable Housing Project
location is at the southeast junction of the intersections of
Main Road (SR 25) at Yennecott Drive and Boisseau Avenue.
The site is currently a partially wooded, undeveloped parcel.
The Affordable Housing Project will consist of 55 single
family homes to be constructed on a 37 acre site. Access to
the site will be provided by one roadway on Boisseau Avenue
and one roadway on YenDecott Drive.. The study boundaries
established for the purpose of this traffic impact analysis
were limited to Middle Road (CR 48) on the north, Main Road
(SR 25) to the south, Boisseau Avenue to the west, and
Yennecott Drive to the northeast (Figure 2).
B. Surroundinq Land Use
Land uses in the immediate vicinity of the proposed
development are a mixture of residential, vacant, and
commercial. Residential homes are located to the north and

west of the proposed site. To the south and east the land is
principally vacant. There are a series of commercial strip
developments along Middle Road (CR 48).
C. Roadway and Hiqhwa¥ Facilities
Turning movement traffic counts were conducted during mid-
November 1988. This time of year does not represent the peak
traffic flow period for the eastern Suffolk region. The
SCDPW has developed a table of factors, which enables a month

obtained during November, 1988. A machine count conducted in
August, 1988 on Middle Road (CR 48) by the SCDPW was used to
validate the August turning movement counts.
The following roads provide access to the proposed
development and surrounding areas:

Middle Road
the entire
(CR 48)
(CR 48) is an important arterial roadway, serving
community of Southold. In the vicinity of the
site, CR 48 is a high capacity, two-lane arterial roadway.
Middle Road extends eastward to Orient Point, and westward to
its junction with Sound Avenue in Matittuck. Middle Road
consists generally of one concrete lane in each travel
direction in the vicinity of the site, with asphalt shoulders
of varying widths and is in generally good condition. The
posted operating speed is 50 MPH and the road is under the
jurisdiction of the Suffolk County Department of Public Works
(SCDPW). The estimated two-way, weekday, August 1988 traffic
volume is approximately 10,000 vehicles per day.
Middle Road (CR 48) at its intersection with Boisseau
Avenue and Yennecott Drive forms a skewed, channelized
intersection. The intersection is controlled by stop signs
at conflict points from the side streets and yield signs at
merges with the County Road. The intersection is controlled
by a series of four raised islands. There is effectively one
travel lane in each direction, with essentially a one-way
operation around the islands.
-4-
Main Road (SR 25)
Main Road (SR 25) is a principal arterial roadway which
serves the downtown community of Southold. It extends
westward from Orient Point to the Town of Riverhead, where it
changes names. The road in the vicinity of the development
has one asphalt travel lane in each direction plus parking
lanes and is generally in good condition. The posted
operating speed is 30 MPH in the vicinity of the site. The
roadway is under the jurisdiction of the NYSDOT. Main Road
is an important arterial for the Southold area since it
connects to the Long Island Expressway and other principal
points to the west.
Main Road (SR 25) at its intersection with Boisseau
Avenue and Hobart Avenue, has one approach lane in each of
the eastbound, westbound and southbound directions. The
south leg of the intersection is a one-way street leading
away from the intersection. Only the north leg of the
intersection is controlled by a stop sign.
-5-
Boisseau Avenue
Boisseau Avenue is a collector type roadway and extends from
Middle Road (CR 48) in the north to Main Road (SR 25) in the
south. The road is a 24 foot wide, asphalt roadway which is
generally in fair condition. The posted operating speed is
30 MPH. The roadway is under the jurisdiction of the Town of
Southold.

November 15 to November 19, 1988. Turning movement traffic
counts were collected between the hours of 7:00 am to 11:00
am and from 2:00 pm to 6:00 pm during the week, while on
Saturday they were counted from 10:00 am to 12:00 noon and
from 1:00 pm to 4:00 pm. These time periods were selected to
reflect the peak commuter travel time periods, as well as
peak recreational traffic flows. The existing traffic flow
patterns obtained from the turning movement counts are shown
in Figures 3 through 8. The results of the turning movement
counts indicated that the peak commuter travel time periods
on Middle Road (CR 48) at Boisseau Avenue and Yennecott Drive
occurred between 7:15 am to 8:15 am and 4:00 pm to 5:00 pm on
weekdays and between 2:30 pm to 3:30 pm on Saturdays. The
peak commuter travel time periods on Main Road (SR 25) at
Boisseau Avenue were 8:45 am to 9:45 am and 4:00 pm to 5:00
pm on weekdays, and from 10:45 am to 11:45 am on Saturdays.
These periods were also correlated with available summer
counts.

The capacity analysis methodology described in the Highway
Capacity Manual, Special Report, of the Transportation
Research Board (1985) was utilized to evaluate the operation
of the key intersections within the project area. The
capacity analysis data are contained in the Appendix. The
results are summarized in Table A and are discussed as
follows.
The intersection of Main Road (SR 25) at Boisseau Avenue and
Hobart Avenue, under existing conditions, experiences an LOS
of C to D and an acceptable V/C ratio for all time periods
analyzed.
The intersection of Middle Road (CR 48) at Boisseau Avenue
and Yennecott Drive was analyzed as if it were five separate
intersections, due to its geometric configuration. Figure 9
graphically separates the turning movements which were
considered in five different capacity analyses. The
supporting data can be found in the Appendix, and is
summarized in Table A. Under existing conditions, all five
groups of traffic patterns at this intersection, experience
an LOS of A to C and an acceptable V/C ratio for all the time
periods analyzed (Table A). The low V/C ratio indicates that

G. Public TransDortation
The Long Island Railroad (LIRR) provides rail service between
Long Island and New York City and has a station in the
vicinity of the proposed development. The Southold Station
for the Ronkonkoma Line is located approximately 3,000 feet
southwest of the proposed development. This station provides
limited commuter service.
The Suffolk County Transit provides bus service on Long
Island. At present, there are a number of lines operating in
the vicinity of the proposed development. Bus route numbers
92 and 9A travel along Main Road (SR 25) to the south of the
proposed development.

SECTION III
FUTURE CONDITIONS
A. TriD Generation
The first phase in the transportation planning process,
required for the evaluation of future traffic conditions, was
a trip generation analysis. This analysis involved the use
of the Institute of Transportation Engineers (ITE) Report,
Trip Generation, (1987). The trip generation factors, as
determined by the ITE report, were applied to the number of
dwelling units for the Affordable Housing Project. This
procedure determines the total number of average vehicle trip
ends resulting from the proposed project. The trip end is
the total of all trips entering plus all trips leaving the
proposed project over a

B. TriD Distribution
The next phase of the traffic analysis involved distributing
the peak hour trips generated by the proposed project to the
surrounding street system. The travel routes to and from the
proposed development were determined by employing the
percentage distribution patterns of existing area traffic
flows that were collected during the traffic counting phase
of the study. The expected peak-hour traffic volumes
generated by the Affordable Housing Project, (as determined
by the trip generation analysis) were applied against the
trip distribution percentages. The results were individually
assigned to the travel network within the Affordable Housing
project area. The projected traffic volumes were then added
to the estimated summertime traffic volumes. These results
represent projected traffic volumes in the year 1990, and are
depicted in Figures 10 through 17 in the Appendix.
C. Traffic ImDact
The final phase in the traffic analysis involved a detailed
investigation of the traffic conditions at each of the key
intersections and the Affordable Housing site access points
(as shown in the Appendix, Figures 10 through 17). The

In evaluating this intersection, the site traffic was all
distributed to this location to evaluate it in a worst case
scenario. In reality, it is common knowledge that a large
percentage of traffic traveling south on Boisseau Avenue turn
onto Hommel Avenue to make use of the traffic signal at Main
Road and Youngs Avenue, (Chief Winters, Southold Police
Department). If the development traffic were reevaluated
allowing for 30% to the Youngs Avenue intersection, then the
capacity analysis under the build condition, would be an LOS
of C.
Middle Road ((IR 48) at Boisseau Avenue and Yennecott Drive
Under the build and no-build conditions, these intersections
will operate at an acceptable LOS during all of the time
periods analyzed. Traffic from the project site will have a
negligible impact on the operation of this intersection,
therefore, no mitigation measures will be necessary, (as
indicated in Table D).

Yennecott Drive at Affordable Housinq DeveloDment Drive and
Tuthill Road
Under the build condition, this intersection will operate at
an LOS of A for all of the time periods analyzed and a good
V/C ratio. The low V/C ratio indicates that there is
adequate roadway capacity to handle the present volume of
traffic. Therefore no mitigation measures will be required.

provided by Peconic Associates, November 2, 1988). The
anticipated traffic volumes eminating from the site are well
within the capacity of the area road system to accept the
demand. The maximum trips generated in any one direction on
this roadway will not exceed 32 vehicles per hour, or one
vehicle approximately every two minutes.
Access to the Affordable Housing Development site on
Yennecott Drive will be accomplished by connecting the
development road to the existing stub road called Tuthill
Road. At its intersection with Yennecott Drive, Tuthill Road
becomes a four legged intersection. Sight distance
measurements indicate that there will be adequate visibility
both to the east and west for vehicles leaving the
development at the area operating speed. This criteria is
established by evaluating the safe sight distance for a
vehicle to turn left out of the development roadway into the
adjoining roadway and attain the posted speed without being
overtaken by a vehicle approaching from the right. Site
distance measurements were conducted in accordance with the
procedures and recommendations of the POLICY ON GEOMETRIC
-17-
DESIGN FOR HIGHWAYS AND STREETS, (American Association of
State Highway and Transportation Officials, 1984). Figure
14-27, B2a on page 792, from the Policy on Geometric Design
for Highways and Streets, was employed in the evaluation,
where at 30 miles per hour a sight distance of 400 feet was
identified as the minimum range for turning out of the
development roadways. The site distance to the west will be
in excess of 500 feet and to the east in excess of 450 feet.
The anticipated trip generations from the site onto this road
are well within the capacity of the area road systems to
accept the demand. The maximum trips to be generated in any
one direction will not exceed 4 vehicles per hour, or one
vehicle every 15 minutes.

LEVEL OF SERVICE FOR SIGNALIZED INTERSECTIONS
LEVEL OF SERVICE A - describes operations with very low delay
per vehicle. This occurs when progression is extremely
favorable, and most vehicles arrive during the green phase. Most
vehicles do not stop at all. Short cycle lengths may also
contribute to low delay.
LEVEL OF SERVICE B- describes operations with delay in the range
of 5.1 to 15.0 seconds per vehicle. This generally occurs with
good progression and/or short cycle lengths. More vehicles stop
than for LOS A, causing higher levels of average delay.
LEVEL OF SERVICE C - describes operations with delay in the
range of 15.1 to 25.0 seconds per vehicle. These higher delays
may result from fair progressions and/or longer cycle lengths.
Individual cycle failures may begin to appear in this level, the
number of vehicles stopping is significant at this level,
although many still pass through the intersection without
stopping.
LEVEL OF SERVICE D - describes operations with delay in the
range of 25.1 to 40.0 seconds per vehicle. At level D, the
· influence of congestion becomes more noticeable. Longer delays
may result from some combination of unfavorable progression, long
cycle lengths, or high volume/capacity (v/c) ratios. Many
vehicles stop, and the proportion of vehicles not stopping
declines. Individual cycle failures (ie., all vehicles cannot
clear intersection during one signal cycle) are noticeable.
LEVEL OF SERVICE E - describes the operations with delay in the
range of 40.1 to 60.0 seconds per vehicle. This is considered to
be the limit of acceptable delay. These high delay values
generally indicate poor progression, long cycle lengths, and high
(v/c) ratios. Individual cycle failures are frequent
occurrences.
LEVEL OF SERVICE F - describes operations with delay in excess
of 60.0 seconds per vehicle. This is considered to be
unacceptable to most drivers. This condition often occurs with
oversaturation. It may also occur at high v/c ratios below 1.0
with many individual cycle failures. Poor progression and long
cycle lengths may also be major contributing causes to such delay
levels.
OVERSATURATION - describes conditions when flow rates
