Re: Project Trip Generation Study
PRE 25-000013
The following trip generation analysis (Level 1 traffic study) was prepared in order to
provide an estimate of vehicular traffic generated by the project for the AM and PM
commute peak hour conditions, as well as the AM and PM peak hours of the site. The
analysis also includes a distribution and assignment of estimated project trips to and from
the site, and an estimate of traffic mitigation fees.
Proposed Project Description
The project site location is on the east side of Lind Ave SW just south of SW 29th St. The
property address is 2900 Lind Ave SW. There is one building on the site and includes
three different spaces; Suite A, B, and C. The present use of the entire building is
warehouse use. The proposed use discussed herein will be located in Suite B.

The business proposed is a tenant improvement modification of the current building’s
floor area of Suite B, which is 40,000 gsf. The area for the whole building is 78,752 gsf.
The building is situated on one

Proposed Work Schedules
The proposed use will be a fully indoor cultivation facility operated primarily by an
automated computer system, which will require minimal on-site staff and will not have a
customer-facing component. Since there is no retail aspect, employees are not required
to be in the facility during typical business hours (8 am to 5 pm).
The employee shifts will be set from 9:30 AM to 6:30 PM to avoid typical peak hour
congestion in the surrounding area. The business model in regards to employee shifts
will be set to ensure the employees have a shorter duration commute, allowing them to
remain focused on operations without unnecessary burnout from excessively long
commute times.
The development of the business will be phased in through two phases, with Phase 1
being the setup phase and Phase 2 will be the full build-out and maximum operations
phase.
Phase 1
For Phase 1, there will be 5 full time employees with 3 working the 9:30 am to 6:30 pm
shift (Monday through Friday), and 2 working the 11:00 am to 8:00 pm shift (Tuesday
through Saturday). Table 1 identifies these shifts.

It is estimated that there will be 3 part time employees that would work during the harvest
times. Harvest time would be three days every other week. The shift would be 9:30 am
to 6:30 pm (Tuesday through Thursday). Table 2 identifies these shifts.

Existing Use
The space utilized in Suite B was formerly used as a warehouse space for new boat
storage. However, the space has been vacant for more than three years. Therefore, no
vehicle trip credit is being considered in this analysis.
Trip Generation
Trip generation for the project is based on the 3 Plus Empire employee schedules noted
above. This analysis includes trip estimates for both Phase 1 and Phase 2.
The trip generation analysis was calculated for the average weekday AM commute peak
hour and PM commute peak hour, as well as the average weekday AM site peak hour and
PM site peak hour. The AM commute peak hour is defined as the peak one hour period
between 7 am and 9 am, and the PM commute peak hour is defined as the peak one hour
period between 4 pm and 6 pm. The site peak hour would be the busiest vehicle activity
for vehicles entering and exiting the site. The AM site peak hour for this project is
estimated to be between 9 am and 10 am, and the PM site peak hour is estimated to be
between 6 pm and 7 pm. The later shift (11 am to 8 pm) is estimated to generate fewer
trips than the earlier shift (9:30 am to 6:30 pm).
Non employee vehicle trips such as shipping, parcel deliveries, garbage collection, and
postal services, are estimated to occur during non street peak hour periods and are
predicted not to occur more than 1 or 2 per week, except for postal services. For
shipping, incoming shipments would typically arrive in the morning between 10 am and
12 pm, and outgoing shipments are likely to be scheduled in the afternoon before 4 pm.
The results of the trip generation analysis are presented in Table 5.

b Phase 2 includes Phase 1 trips.
As shown in Table 5, the proposed project is not estimated to generate any trips during
the AM or PM commute peak period. For the site peak hour, the project is estimated to
generate 6 AM and 6 PM site peak hour trips based on a monthly average of weekday
trips.
It is estimated that all of the majority of the vehicle trips would arrive 5 to 10 minutes
prior to their scheduled start, and would depart within approximately 15 minutes after
their schedule ends. Thus, for the site peak hour, all of the trips are estimated to arrive
around 9:15 am or later, and all of the trips are estimated to depart around 6:45 pm.
A detailed summary of trips for each employee by shift for a 4-week period (representing
a typical month) for Phase 1 for both the AM and PM shifts are shown in Attachment 1.
The same detail for Phase 2 is shown in Attachment 2.

City Traffic Impact Fees
The City’s PM peak hour traffic impact fee for land uses not identified on their impact
fee schedule is $8,031.94 per PM commute peak hour person-vehicle trip, where the PM
peak hour is defined to be one hour between 4:00 pm and 6:00 pm.
The project is not estimated to generate any trips during the PM commute peak hour.
Consequently, the traffic impact fee is presumed to be $0.
Summary
This Level 1 traffic study including trip generation analysis, trip assignment, and
mitigation fee assessment was conducted for the tenant improvement within Suite B of
the warehouse located at 2900 Lind Ave SW. The existing building space being
renovated will not change in size.
The trip generation findings indicate the project will not generate any vehicle trips in
either the AM or PM commute peak hour. The City of Renton traffic study guidelines
indicate that if the new trips as a result of redevelopment result in more than 20 (net) new
trips in the AM or PM commute peak hours, a full traffic impact analysis will be
required. As shown in this report, the new use will NOT generate more than 20 net new
trips or even simply any new trips in either commute peak hour. As a result, a full traffic
study is presumed not to be required. The existing use of the space has been vacant more
than three years thus there would be no credit for existing trips.
Since the proposed new use project trip generation estimate is estimated not to generate
any vehicle trips in the PM commute peak hour, the City traffic mitigation fee is
estimated to be $0.
