From: Robin Bousa Re: Trip Generation Compar.son to Support Gateway Hills Variance
Managing Director for Apartments & Townhouses at Gateway Hills
Nashua Technology Park — Spit Brook Road, Nashua, NH
This memorandum has been prepared to support the variance request for the portion of the Gateway Hills
development program that was previously intended to house 240,000 SF of research and development (R&D) space
in two buildings at Nashua Technology Park located off Spit Brook Road in Nashua, NH. The property is located
behind (north of} 100, 200, and 300 Innovative Way, east of Research Drive, and south the Tara Heights Apartments
(see Exhibit 1). In lieu of the research and development space, the John Flatley Company proposes to construct
approximately 268 apartment units and 28 —
townhouses.
Trip Generation
Trip generation estimates for the 240,000 SF of
research and development space and the
residential units were calculated using rates
published by the Institute of Transportation
Engineers (ITE) in Trip Generation’. As shown in
Table 1, a direct comparison of the R&D and
residential development programs shows that
the residential uses will generate substantially
less traffic than the R&D use. More specifically,
the residential uses are expected to generate 215
fewer trips entering the site during the weekday
morning peak hour, but 30 more trips exiting -
for a net difference of 185 total fewer trips.
During the weekday evening peak hour, the
residential land uses are expected to generate 35
more trips entering the site, but 165 fewer
exiting — for a net difference of 130 trips.
Supporting trip generation calculations are
attached herein.
