3. TRIP GENERATION
Trip generation estimates are typically derived from the Institute of Transportation
Engineers (ITE) publication, Trip Generation Manual, 11th Edition. This reference
includes trip generation for some of the proposed uses (small office, self-storage) but
not all the proposed uses. Trip generation for some of the specialty uses was derived
from the expected activity levels for those uses.
Trip generation for the previous use was also estimated and taken for credit against
the proposed uses. For the WACC, some uses will occur daily, and others
infrequently. The site is expected to have a small retail space, some small office
spaces with a library, a group tutorial room, and some storage space for the
community. Another area marked “gathering area” will be used infrequently. The
gathering area is for Friday evening board meetings twice per month with possibly
occasional uses on weekends. Weekday trip generation for each use is discussed
below.
3.1 Data Collection – Specialty Retail Store
The retail space will be occupied by a specialty retail shop that sells food products,
clothing, and other items from West African cultures. This space is 4,067 square feet
(sf), inclusive of a retail storage area. An existing West African retail store has been
open for several years in the Hillman City area of Seattle. Because this is a niche type
of land use, field data was collected at that store to determine trip generation for the
retail space at the West African Community Center site. Video captured people
entering and exiting the store over a three-day period (Tuesday, April 22 through
Thursday, April 24 of 2025) with counts spanning 9:00 AM to 9:00 PM.
PM Peak Hour Trips: The peak hour of activity for each day was determined by
reviewing counting person trips from 3:00 to 6:00 PM. The one hour reflecting the
highest trip totals was then identified as the peak hour. Because of the site location
(no dedicated on-site parking), counts consisted of tracking ins and outs at the
entrance door. As a result, the mode of travel (e.g., walking, transit, or vehicle) could
not be distinguished.
Peak hour volumes ranged from 25 to 28 person trips (ins plus outs). These values
were averaged to determine the typical PM peak hour of activity, resulting in an
average of 26 trips. Of these, approximately 49% were entering the site and 51%
were exiting. Note than a portion of these trips were likely from walkers; however, this
could not be confirmed with the video footage and therefore are all treated as vehicle
trips.

Daily Trips: Daily trips were also reviewed and showed an average of 187 daily trips
(ranging from 158 to 204 person trips per day). Daily trips are 50% entering, 50%
exiting.
AM Peak Hour Trips: The store opens at 9:00 AM which falls outside the typical AM
peak period. However, a store employee entered and exited a few times during the
AM peak period. Therefore, 4 trips are used for the AM peak hour.
Store Comparison: The existing store in Hillman City has about 3,000 sf. The
proposed retail space at the West African Community Center has about 4,067 sf.
However, two factors mitigate against increasing the trip generation for the new
store:
1. The existing store has no storage area. Storage items are set in the aisles or
crammed onto the shelves. The new retail storage area will allow those items
to be placed in a separate space. The aisles in the new store can also be
spaced further apart to enhance the customer experience. Because of this, no
increase in trips is expected. See photos in the appendix from the existing
store.
2. The West African community around the existing store in Seattle is much larger
than that in the Renton area. With a smaller potential customer base, trip
generation at the proposed Renton location is anticipated to be comparable or
lower to the Seattle location.
3.2 Group Tutorial
The site will host group tutoring during weekdays. Tutoring sessions will begin at
1:30 and 3:30, and last one to two hours. About 10 people per session, or 20 per day,
may be tutored at the site, with two tutors assisting them. This use would result in an
estimated 28 daily trips. This assumes some carpooling for students, as the tutoring
session students are from the local West African community. No AM peak hour trips
are expected for the tutoring; all tutoring takes place in the afternoon.
3.3 Office Space
The site will include about 2,725 sf of office space and a library. Some office space is
for use by the Board president and one or two employees/volunteers. There are
other small office spaces for counseling. Trip generation for office space was based
on the Institute of Transportation Engineers (ITE) Trip Generation Manual, 11th Edition,
using Land Use Code (LUC) 712 – Small Office. Per thousand sf was used for the
variable, and average rates were applied.
