Re: Traffic ~pact Assessment
Proposed Residential Development
56655 Main Road
Southold, ~
Dear Mr. Read:
As requested, Dnnn Engineering Associates PC has completed our professional traffic engineering
evaluation in connection with the above project. The project envisions the construction of 24 semi-
attached residential condominium units for senior citizens, with associated amenities, and 3
affordable housing units. The senior condominium units will be contained in 8 separate buildings of
3 units each, and the 3 affordable housing units will be contained in a separate building. The 6.75
acre site is located on the north side of Main Road, NYS Route 25, in the hamlet of Southold,
Suffolk County, New York. The current site plan proposes a single access to Main Road. At present,
the site contains a single-family residence.
Figure 1 shows the location of the project site and Figure 2 shows the boundaries o fthe property and
the adjacent roadway network.
Our examination was performed to evaluate the potential traffic impact of the proposed
development, including trip generation, access and safety. During the course of the study, the
following specific work tasks were performed:
Several personal visits to the site were made to attest to our observations of existing traffic
movements at various times of the day and under different conditions.
Data regarding traffic flow on Main Road was obtained and analyzed from the New York
State Department of Transportation.
Trip generation estimates were performed, utilizing information contained in the Institute of
Transportation Engineers report "Trip Generation", 8th Edition, the accepted industry
standard for applications of this nature.

4. The proposed access arrangement was evaluated, from the standpoints of location and design.
The following sections present the results of our efforts in this regard.
Existing Conditions
Main Road, NYS Route 25, is a New York State highway facility that provides direct access to the
site. Although NYS Route 25 extends the entire length of Long Island, it serves as Main Street for
many of the communities along the north fork of Long Island. Near the site of the proposed
development, Main Road provides one lane in each direction, flanked by shoulders where parking is
permitted. The posted speed limit is 30 mph, but changes to 40 mph just east of the site. The site is
located on the eastern end of the commercial center of the hamlet of Southold, and development
along Main Road near the site is primarily commercial, although east of the site Main Road is
residential in nature. According to information provided by New York State Department of
Transportation, the Average Annual Daily Traffic (AADT) on Main Road in Southold in 2006 was
7400 vehicles per day. AADT is a transportation engineering and planning term defined as the
average traffic volume at a given location on any day of the year, including weekends. It is not
utilized in detailed analysis calculation, but rather provides a sense of the order of magnitude of the
daily traffic activity on the facility.
Due to the seasonal, recreational nature of the area, traffic volumes on the adjacent roadways are
higher during the summer months. Based on information provided by the New York State
Department of Transportation, traffic volumes on state highways similar to Main Road can be nearly
40% higher during June and July than an average month, and more than double those found during
winter months. Therefore, daily traffic volumes on Main Road during the summer months can be
expected to be as high as 10, 400 vehicles per day near the site.
In 2006, NYSDOT completed an improvement project on Main Road near the site. The project
included drainage improvements and resurfacing, but no capacity improvements. Therefore, Main
Road still provides one lane in each direction flanked by ten-foot shoulders.
Future Site Trip Generation
The current site plan for the proposed development envisions eight buildings containing 24
residential condominium units for seniors, and a ninth building providing 3 un/ts of affordable
housing. Information contained in the report "Trip Generation", 8th Edition, published by the
Institute of Transportation Engineers, was utilized to estimate the number of new trips that can be
expected to be generated by the proposed project. Land Use Code 252, Senior Adult Housing -
Attached, was utilized to estimate the number of new trips which can be expected to be generated by
the senior housing aspect of the development, and Land Use Code 230, Residential
CondominiumfTownhouse was utilized for the three units of affordable housing. The results of this
analysis are presented in Table 1. As can be seen, during the weekday AM peak hour, the site will
Mr. Christopher Read
February 2, 2009
Page 5
generate 14 new trips, 5 entering and 9 exiting. Similarly, during the weekday PM peak hour, the
development will generate 10 new trips, 6 entering and 4 exiting. Finally, during the Saturday
midday peak hour, the project will generate 12 new trips, 5 entering and 7 exiting. This is a
relatively small amount of new traffic, and it is not anticipated that this small number of new
vehicles would have a perceptible impact on traffic flow conditions on Main Road.
It should be noted that the number of trips shown in Table I was calculated based on the highest rate
of trip generation at any of the developments studied in the Trip Generation report. This was done
because the number of units in the proposed development is very small compared to those studied in
the Trip Generation report, and in general, the developments with a smaller number of units tended
to have the higher rates of trip generation per trait. It should also be noted that the existing single
family home on the site currently generates some traffic, but this existing traffic has been ignored for
purpose of this report. In this manner, the trip generation analysis provides a conservative estimate of
the mount of traffic expected to be generated by the proposed project.

Access Examination
In keeping with good access management practices, the site plan for the project proposes a single
driveway on Main Road. The driveway will serve both the senior housing and the affordable
housing. The site plan indicates that the driveway will be located at the westerly end of the property,
and will provide two lanes, one for entering traffic and one for exiting traffic. Left and right turns
into and out of the site will be permitted at this access driveway. All parking areas provided on the
site can be accessed from the driveway.
Main Road has both vertical and horizontal curvature near the site. The crest of the vertical curve is
just east of the site. The site is also located on the inside of a horizontal curve. Sight distance
Mr. Christopher Read
February 2, 2009
Page 6
measurements were performed to ensure that adequate sight distance would be available at the
location of the proposed site access driveway to allow for safe operations. The 2001 edition of the
American Association of State Highway and Transportation Officials (AASHTO) publication "A
Policy on Geometric Design of Highways and Streets" indicates that for design speeds of 35 mph,
390 feet of sight distance should be available for vehicles entering an intersection to safely do so. In
addition, for design speeds of 35 mph, AASHTO recommends that 250 feet of stopping sight
distance be available for drivers of vehicles traveling on the main road to see a vehicle entering the
road and stop safely, and for design speeds of 45 mph, 360 feet of stopping sight distance be
provided. The 45 mph design speed was included because the speed limit on Main Road is 40 mph
just east of the site, so westbound vehicles on Main Road approaching the site might be traveling
slightly faster than eastbound vehicles, which would have a 30 mph speed limit. Sight distance
measurements performed at the location of the proposed driveway indicate that stopping sight
distanee of 400 feet to the east and over 800 feet to the west is available. Therefore, adequate sight
distance is available for safe operation of the proposed driveway.
Conclusions
Based on the professional transportation engineering evaluation described above, it is concluded that
the proposed 27-unit residential development will result in a small number of new trips added to the
surrounding roadway network. The single access point to the proposed development is located to
provide adequate sight distance for vehicles to safely enter and exit the site bom Main Road.
Therefore, the proposed 27-unit residential development will have minimal to imperceptible impact
on the safety and operation of the roadway facilities.
If you have any questions.~°r need any further information, please call me.

Mr. Corrado has been with Dunn Engineering Associates since 1989 andihe-- h~s'~e'Kf~h~iYe experience ia every ~p~.~.t.of
transportation engineering and planning projects, from large, regional plannitig studies recite-specific examig~i0~"~ projects
having local impact. His experience encompasses all aspects of the conduct 6f th~~~tii~iies, from seeping through the anthomhip
of the final report, including formulation of the data collection plan, data analysis, and the development of improvement or
mitigation strategies, depending on the nature of the study. He participated in the development and implementation, and had
direct supervisory responsibility for the data acquisition plan used in the Long Island Transportation Plan to Manage
Congestion, LYI3~000, one of the largest field a'affic data collection efforts performed on Long Island. Mr. Corrado also
managed the Corridor Study for Suffolk County Road 58, Old Counny Road, and the Corridor Study of CR97, Nicolls Road, for
Suffolk County Department of Public Works. He also authored the L1TP2000 project reports on Cargo Movements and on Land
Use and Zoning.
Mr. Corrado also has extensive experience in traffic signal design, and managed DEA's efforts under the TOPICS IV project for
the New York City Department of Transportation. DEA's efforts on this project produced design plans for the modernization of
169 a'affic signals in Queens, the Bronx and Brook/yn, and construction support for the implementation of the ultimate design..
All told, the TOPICS 1V added over 2000 signals to the City's computerized traffic signal control system.
Mr. Corrado has extensive experience in the area of public participation in the transportation planning process. He served as
consultant facilitator for the Subcommittee on Cargo Movements for LITP2000 and was directly involved in the public
information effort for the project. He also developed and implemented the public participation efforts for both the CR97 and
CR58 Corridor Studies, and took part in public information efforts for several other corridor studies for SCDPW and NYSDOT.
In his previous position as Operations Manager at Stern Metals from 1984 to 1989, Mr. Cormdo had direct responsibility for the
operation of a multimJllion-dollar manufacturing facility, including the supervision of an 80-plus person staff. This hands-on
management experianco has served him well in his project management responsibilities at DEA. His maj or project experience
includes:
Project Manager/Principal Planner, County Road 58 Corridor Study, Riverhead, NY - DEA has recently completed
the Corridor Study of County Road 58, Old Country Road for SCDPW, from the Long Island Expressway to County Road
I05 in Riverhead. This study is the third Corridor Study DEA has performed as primary consultant for Suffolk County in
addition to three others that DEA has provided traffic-engineering expertise as subconsultant. DEA's technical proposal
Westhampton Beach, New York
Dunn Engineering Associates, P.C.
was rated highest by the County due to our familiarity with County Road 58 and our demonstrated ability to use innovative
techniques m solve unique problems. DEA used high-resolution videography to record license plate data in the corridor,
which was then transcribed using optical character recognition software. Utilizing this data, license plate matching
techniques provided information on trip making patterns within the corridor, especially at the "Riverhead Traffic Circle".
Improving operating conditions at the traffic cimle was deemed a critical part of the project. While under previous projects
DEA had analyzed the circle using SIDRA, for this project, VISSIM, a micro-simulation model designed to handle traffic
circles as well as signalized intersections, was used. VISSIM, in combination with the high quality input data derived from
the videography effort, produced a platform to thoroughly test and evaluate improvement strategies for the corridor,
including five different scenarios for the traffic circle. The model is also capable of providfug 3-D simulation. (2004-2005)
Project Manager/Principal Planner, CR97/Nicolls Road Corridor Study, SCDPW - The federally aided project, being
progressed under the guidelines set forth in the Procedures for Locally Administered Federal Aid Projects, will result in an
Expanded Project Proposal 0EPP) for improvements to the facility. Responsibilities include overall management of the
project, including supervision of four subcontractors, design and management of the public participation plan for the
project, development of transportation alternatives, design and supervision of all data collection conducted for the study,
including traffic volumes, travel time speed and delay studies, bridge condition of 17 bridges, liaison with County, State
and FHWA officials, as well as with local elected officials, design and management of a project website, and full
responsibility for the production of project documents. Nicolls Road is a major north-south arterial, linking Suffolk
County's major east-west corridors: Montauk Highway (County Road 80), Sunrise Highway (New York State Route 27),
the Long Island Expressway (I-495), Portion Road (CR16). Middle Country Road (NYS Route 25), Nesconset Highway
(NYS Route 347) and North Country Road (NYS Route 25A, and providing direct access to the SUNY Stony Brook
Campus, the Suffolk County Community College Campus, and the University Hospital at S~ony Brook, as well as indirect
access to large areas of residential and commercial development. The study will make projections regarding future
conditions and provide scoping for future transportation improvement projects on CR97 between Sunrise Highway (NYS
Route 27) in the south to North Country Road (NYS Route 25A) inclusive, in the north, in Islip and Brookhaven Towns.
(2001 - present)
Project Engineer, Long Island Transportation Plan to Manage Congestion (LITP 2000) - The Study provided an
integrated multimodal transportation program for managing congestion on the State highway system and on selected local
roadways within Nassau County and most of Suffolk County. The program emphasized travel demand management
(TDM), transportation systems management (TSM), and public transit solutions as complements to traditional highway
capacity improvements. Responsibilities included development and implementation of a detailed field data collection plan
for input into a regional computer simulation of the entire study area. Also responsible for the preparation of the project
reports, "Plans and Policies: Local Governments with Jurisdiction Over Land Use and/or Growth Management" and the
Cargo Movements Existing Conditions Technical Memorandum, both of which were included in the final project and the
development and implementation of an in-depth survey of multi-modal freight movement operations within this study area.
(1998 to 2004)
Project Engineer, New York City DOT TOPICS IV Traffic Signal Computerization - This NYCDOT project provides
the 'design and implementation of the addition of over 2000 signalized intersections to the existing New York City
computerized traffic signal control system. Detailed design for the full or partial modernization of 169 traffic signals in the
Bronx, Brooklyn and Queen~, NY so that these locations could be added to the existing signal system. A number of the
signals retained the two-color, red-green display, and so required complete redesign and replacement of all traffic signal
equipment. In addition, a new traffic signal controller was designed for the project. (1998 - present)
Project Engineer, North Fork Recreational Transportation Needs Assessment - This study evaluated the special
transportation needs of this unique rural and recreational area of Long Island. The findings were incorporated into the
recommended program of the LITP 2000. The plan provided the NYSDOT and the Towns of Rivethead, Southold and Shelter
Island with an overview of the total transportation system now and in the futura, and identified strategies best fit to maximize
safety, mobility and system capacity, while maintaining or improving the rural character of the North Fork. Responsibilities
included day-to-day project management, liaison with local officials, formation and coordination of Technical Advisory
Committee activities, development and execution of data collection plan, project documentation, and development and

in throughput and capacity was required for the MPT schemes by the involved agencies. Heavy vehicle detour plans were
also developed, as well as stretches tn maintain pedestrian capacity in and around this vital transportation hub during
construction activities. (1999)
Project Engineer, Rehabilitation of the World Trade Center Truck Dock Floor Slab, Port Authority of New York
and New Jersey - The project provided for the removal and replacement of the reinforced concrete floor slab on the truck
loading level of the World Trade Center in New York City. Responsibilities included the development and design of a
phased Maintenance and Protection of Traffic strategy for the duration of the project. As this was the only loading facility
for the entire 7-building, 12,000,000 square foot World Trade Center complex, maintaining safe and efficient access
through well-designed and implementable maintenance and protection of traffic strategies was vital to the function of the
complex. Construction support and contractor shop drawing and cut sheet review was also provided throughout the project.
The project was 90% complete at this time of the destruction of the complex in 2001. (1998-2001)
