SUBJECT: 22019 SR 99, Edmonds, WA
Comparative Trip Generation Analysis of Proposed Commercial Redevelopment
TENW Project No. 3496
This memorandum summarizes the results of a comparative trip generation of the proposed
commercial redevelopment at 22019 SR 99 in Edmonds, WA. The project would remove an
existing 6,185 square -foot medical office building with a smaller commercial building that would
comprise a 3,400 square -foot bank (with drive thru) and a 2,400 square -foot coffee shop (with
drive thru). An existing access driveway onto SR 99 would also be removed as part of the project.
Project Trip Generation Analysis
Published trip rate equations compiled by the Institute of Transportation Engineers (ITE) Trip
Generation, 91' Edition, 2012, were used to estimate daily and p.m. peak hour traffic that would
be generated by the proposed redevelopment assuming a new Coffee Stand (with Drive Thru) (ITE
Land Use Code 936) and a new Bank (with Drive Thru) (ITE Land Use Code 912), with
consideration of removal of the existing Medical Office Use (ITE Land Use Code 720). Pass -by
rates for both proposed drive-thru uses were estimated using rates published in the Trip Generation
Handbook, 31d Edition.
As shown in Table 1, an estimated net increase of approximately 332 daily and 31 new p.m.
peak hour vehicular trips (22 entering and 9 exiting) would be generated with redevelopment of
the site when applying standard trip generation rates. A detailed summary of trip generation
calculations is provided in Attachment A. It should be noted, that no adjustment in vehicle mode
share given transit service along SR 99, nor for internalization between proposed land uses and
other on-site uses. Given the net increase in site trip generation, no off-site traffic operational
impact analysis appears warranted.
