Skinner View Townhouses - Traffic Analysis
30 Williams Street, Northampton, MA
The property is comprised of two (2) parcels totaling 1.23 acres. The proposed development will
be located on parcel 2, which is comprised of 38,132 square feet (0.87 acres) of undeveloped
land. Parcel 1 consists of an existing single-family structure, a studio space, and a barn, with
associated driveway and parking spaces. Parcel 1 will remain developed as is currently, with
some minor site work added. The proposed project will consist of 6 new Townhouse units.
The close proximity of Skinner View Townhouses to downtown Northampton will allow
residents to walk or ride their bikes to downtown amenities within minutes. At the same time,
the location of the property provides the residents the feeling of living in the country, at the
outskirts of the city, by the dike with access path to the walkway along the dike.
A narrow driveway of 15 feet is designed to give access to both the resident's vehicles, and
pedestrians. The pedestrian's alignment is delineated within the driveway at the same surface
elevation, using color and texture that will clearly mark the traffic pattern of both users. The
driveway will only serve the residents of the Townhouses and the speed limit will be limited to
15 MPH. This design promotes traffic calming and with that, will improve the safety of motorist,
pedestrians and cycling within the complex.
Each unit will offer two bedrooms and will range in size from 1,000 to 1,500 square feet of
living space. This type of development best meets the definition of a condo/townhouse
development by the Institute of Transportation Engineers (ITE) classification.
Trip generation rates for the proposed project were obtained from the Trip Generation Manual,
9th Edition, published by the Institute of Transportation Engineers (ITE). Table 1 provides the
daily am peak hour, and pm peak hour trip generation calculations for the proposed project. As
shown in the table, the maximum number of units per plan (6) would generate a total of 36 daily
trips, 5 am peak hour trips, and 6 pm peak hour trips.

This analysis yields insignificant traffic generated by this proposed 6-units, therefore the level of
service (LOS) is not expected to change in the adjacent roadways.
