Trike Stop Daycare Center Trip Generation & Mitigation Memorandum
1. DEVELOPMENT IDENTIFICATION
Gibson Traffic Consultants, Inc. (GTC) has been retained to analyze the traffic impacts of the
proposed tenant improvement of the Trike Stop Daycare Center. GTC is a professional traffic
engineering consulting firm registered and licensed in the State of Washington. This study has
been organized in the manner of the SEPA Traffic Impact Requirements for the City of Edmonds
for developments generating less than 25 PM peak -hour trips.
GTC is located at:
2802 Wetmore Avenue, Suite 220
Everett, WA 98201
Phone: 425-339-8266
Fax: 425-258-2922
Email: info@gibsontraffic.com
Matthew Palmer, responsible for this report and traffic analysis, is a licensed professional
engineer (Civil) in the State of Washington and member of the Washington State section of ITE.
The proposed Trike Stop Daycare Center tenant improvement will consist of replacing 8,609
Square Feet (SF) of office space with a daycare center with the capacity for 99 students. The site
address is:
23105 100"' Avenue W
Edmonds, WA 98020
The proposed tenant improvement is anticipated to be operational at the end of 2015/early 2016.
The property currently is served by the existing accesses on to 100`' Avenue W. No change in
access is proposed; therefore, no sight distance or access analysis was performed.

Trike Stop Daycare Center Trip Generation & Mitigation Memorandum
2. TRIP GENERATION
Trip generation rates were obtained from the Institute of Transportation Engineers (ITE) Trip
Generation, 9th Edition (2012). The average trip generation rates for ITE Land Use Code (LUC)
565, daycare center, and ITE LUC 710, office, have been used for the trip generation
calculations.
Daycare facilities have pass -by trips associated with parents dropping off children in the
morning before work and picking up children in the afternoon after work. These trips are not
new trips generated by the development since these trips are currently on the surrounding
roadway system. GTC had submitted a report in 2009 for the Grow with Us Daycare which
included data collected at the North Creek County Day School that shows a pass -by rate of 69%.
This pass -by rate has been applied to the trip generation for the Trike Stop Daycare Center.
GTC's study for the Grow with Us Daycare is included with this report. This pass -by rate
should be considered conservative since Snohomish County allows a 75% pass -by rate for
daycares on arterials and 100th Avenue W would be classified as an arterial by Snohomish
County. This pass -by reduction has been applied to the daily, AM peak -hour and PM peak -hour
trip generation calculations.
The tenant improvement is anticipated to generate 39.46 net new ADT, with 11 net new AM
peak -hour trips (1 inbound/10 outbound) and 12 net new PM peak -hour trips (10 inbound/2
outbound). The trip generation is summarized in Table 1.

3. TRAFFIC IMPACT FEES
Traffic impact mitigation payments to the City of Edmonds are based on Edmonds Road Impact
Fee Rate Study Table 4, Impact Fee Rates. The 2009 Impact Fee Rate Table was used to
determine the new fees and credit for the removed 8,609 SF of office. There is a land use for
Day Care Center; however, it is not applied per student and it uses a % New Trips of 75% which
doesn't take into account the higher pass -by which would result in a % New Trips of 31 %. GTC
utilized the trip rate from ITE per student of 0.81, the lower % New Trips of 31%, the same Trip
Length Factor (0.67) from Table 4 (Impact Fee Rates) and the $1,049.41 per Trip fee to calculate
a fee per student.
The traffic mitigation fee calculation for the Trike Stop Daycare Center tenant improvement is
summarized in Table 2. The total traffic mitigation fee calculations results in a credit of
$342.18.

Re: Grow with Us Daycare — 49 Student Daycare on Edmonds Way
Updated Traffic Impact Analysis, GTC #09-079
Gibson Traffic Consultants (GTC) is providing updated text to address comments from
the City of Edmonds pertaining to a discrepancy in Table 1 and credit for the existing
single-family residence. We have included the other sections of the report for
consistency with the original report. This study has been organized in the manner of the
SEPA Traffic Impact Requirements for the City of Edmonds for developments generating
less than 25 PM peak -hour trips.
DEVELOPMENT SITE DESCRIPTION
The Grow with Us daycare is proposed to remodel an existing single-family residential
unit and construct an 832 square foot (SF) addition. The daycare is proposed to total
2,273 SF of daycare that will be approved for 49 students. The development site is
located at 665 Edmonds Way in Edmonds, Washington. The proposed development is
anticipated to be occupied in 2010. The development is proposed to have two one-way
access points, one each for inbound and outbound traffic. The outbound access will be
the farthest from the signalized intersection of Edmonds Way at 226`h Street SW.
TRIP GENERATION
Trip generation rates were obtained from the Institute of Transportation Engineers (ITE)
Trip Generation, 8"' Edition (2008). The average trip generatioti rates for ITE Land Use
Code (LUC) 565, daycare center, and ITE LUC 210, single-family detached housing,
have been used for the trip generation calculations.
Daycare facilities have pass -by trips associated with parents dropping off children in the
morning before work and picking up children in the afternoon after work. These trips are
not new trips generated by the development since these trips are currently on the
surrounding roadway system. GTC collected data at the North Creek County Day

School, which has similar uses to the Grow with Us daycare. GTC's data shows a pass -
by rate of 69%. This pass -by rate has been applied to the trip generation for the Grow
with Us daycare. GTC's study for the North Creek Community Day School is included
with this report. This pass -by rate should be considered conservative since Snohomish
County allows a 75% pass -by rate for daycares on arterials and Edmonds Way would be
classified as an arterial by Snohomish County.
The Grow with Us daycare, based on a capacity of 49 students and the removal of one
single-family residential unit, will generate 58.48 new average daily trips (ADT) with
11 AM peak -hour trips (6 inbound/5 outbound) and 11 PM peak -hour trips (5
inbound/6 outbound). A summary of the trip generation has been included in Table 1.
Table 1: Trip Generation Summary
The trip generation calculations have been included in the attachments.
ACCESS ANALYSIS
The development is proposed to have an internal one-way loop. Inbound traffic will
enter at the east edge of the property and the outbound traffic will exit at the west edge of
the property. This configuration should maximize the efficiency of the flow of traffic on
the site.
An information sight distance analysis was performed using the Washington State
Department of Transportation (WSDOT) SRWeb application, which has photos taken at
street level along all of WSDOT's routes. It appears that there is adequate sight distance
in both directions from the access.

TRAFFIC IMPACT FEES
Traffic impact mitigation payments to the City of Edmonds are based on Edmonds Road
Impact Fee Rate Study Table 4, Impact Fee Rates. The table does not have a rate for
daycares and therefore GTC has calculated the traffic impact fee based on the new PM
peak -hour trips generated by the development, a mitigation fee of $736.66 per PM peak -
hour trip and an estimated trip length factor.
The average trip length for the City of Edmonds is not included in the City of Edmonds
Tragic Impact Analysis Requirements and GTC staff was unable to obtain from City of
Edmonds staff what average trip length was used in the traffic impact fee calculations.
The trip length factor has therefore been calculated from data used by Mirai Associates in
the City of Monroe. An average trip length of 2.0 miles was used in the traffic impact fee
calculations for the City of Monroe. An average trip length for Grow with Us daycare
patrons was calculated to be 1.075 miles, based on data provided by the applicant for a
similar center under the same ownership. This data results in a trip length factor of
0.5375 for the daycare. This trip length factor is similar to the factor used by the City of
Edmonds for high schools. The calculated trip length factor should therefore be
appropriate since daycares and high schools have similar trip types and there are more
daycare alternatives than high school alternatives, which would reduce the trip length for
daycares. It should be noted that the calculated daycare trip length adjustment factor
could be reduced if the average trip length for the City of Edmonds is greater than the 2.0
mile trip length form similar cities that GTC used. Table 4, Impact Fee Rate and the
Mirai Associates are included with this report.
The Grow with Us daycare is anticipated to generate 12 PM peak -hour trips per Table 1,
which results in 6.45 PM peak -hour trips when multiplied by the trip length adjustment
factor. The traffic mitigation fees for the Grow with Us daycare are $4,751.46. Per
Table 4, Impact Fee Rate (City of Edmonds) the credit for the existing single-family
residence being removed is $840.72; therefore, the total mitigation fees the Grow with Us
daycare will be responsible for is $3,910.74.

GTC trusts that this updated memorandum and attachments adequately address the trip
generation and traffic impacts of the proposed Grow with Us daycare development. If
there are any questions or comments, please contact GTC at (425) 339-8266.

CASE
RE 1,10W3 - North Creels Country. Day School (T"C # 92-038)
Trciffic Impact Study for proposed School Expansion -
Dear Mr. Stone:
Backar Gibson Traffic Consultants (GTC) has been hired: by Jane Heusse (Owner/
Applicant), to complete a traffic assessment of trip generation and mitigation
requirements for the proposed expansion of the North Creek Country Day School on
196th Street SE west of SR -527 in Snohomish County (see Figure 1). We have reviewed
your preliminary comments for the subject project (December 19, 1991 memorandum to
Ernie Jensen). It was determined that the subject project is located within Transportation
Service Area '" '° This traffic assessment memorandum addresses trip generation/
distribution, existing LOS conditions and the impacts of the proposed development on the
affected County road system per the requirements of the new Title 26.8 ordinance. Note:
This project would only generate four (4) new PM peak trips and thus, the recent Traffic
Impact Analysis Checklist from WSDOT District 1 is not applicable. However, the newly
signaiized intersection of SR -527 and 196th Street SE (as part of WSDOT's Phase 1
improvements to the SR -527 corridor) was analyzed since a critical access intersection.
196th Street, which dead -ends just west of the project .site, would handle 100 % of site
traffic east to SR -527. , ,
Descriotion of Eqr t Nis CUP application
proposes to expand an existing pre-school, elementary and extenued day-care facility on
t.- 3 4 -acre site at 1510 -196th Street SE. Two (2) pre-school classes, one K-3 elementary
class and AM/PM daycare classes are being conducted at the North Creek Country Day
School, using a converted single family residence and garage at present.. The site
proposal calls for construction of a new 28' x 56' structure to house .two (2) new
classrooms for new elementary and pre-school students. There are presently 73 students
enrolled at the school, with 18 new students projected for the 1992-93 year and 9
additional students projected by 1994-95 (total student enrollment of 99).
Access to the site would be provided via two driveways (Inbound west access and
outbound east access). Both driveways have a gravel surface at present, but would be
paved with site construction along with the parent drop-off/pickup loop and 14 on-site
parking stalls (see Site Plan). The inbound driveway would be located approximately 225
feet east of the North Creek Bridge, while the outbound driveway would be located within
an existing 30 -foot access easement near the east property boundary (110 feet east of
west/inbound entrance).

TRIP GENERATION
Exlstirt Tr ffic & Trav l MoSIgs, An origin -destination and travel mode survey of the
existing 73 students in preschool and K-3 classes was conducted by Edith Christianson,
manager of the North Creek County Day School. Parents of students were surveyed to
determine trip origin, travel mode, and trip time data. Three (3) distinct groups were
identified in the travel survey: 1) Single occupant vehicle (SOV) coming directly from
home or college to school; 2) SOV vehicle dropping off student(s) on way to work, and,
3) carpool vehicle (HOV) with student(s) riding with school staff or sibling. As
summarized in Table 1, the existing school generates an estimated 150 ADT on an
average weekday with a total of 75 vehicles (66 parent and 9 staff). - Ove; two-thirds (69
%) are pass -by trips by SOV or HOV vehicles. Thus, new site trips by SOV or HOV
vehicles arriving from homes or nearby colleges represent 31 of daily site traffic. Note:
Non of the students presently walk, or bike to school and parent/staff vehicles represents
nearly 100 % of daily site traffic.

4220.060 Traffic Counts
Adopted: 1/1/03, First Revision 10/11/04
(1) Traffic Studies provided for large developments will need to include traffic counts for any impacted
key intersections on critical arterial units. These counts are necessary to estimate future volumes and to
support the forecast assignments of trips from the development at the intersections.
(2) DPW has a regular program of conducting traffic counts and may be able to provide the developer
with acceptable counts. DPW will determine whether or not specific available traffic counts are
acceptable. For purposes of future analysis of level of service for traffic studies, the count date should
not be more than one year prior to the submittal date of the report. An older count is only acceptable with
prior written permission from the department. For other purposes, such as screening or assistance with
trip distributions, counts may be up to two years old. When acceptable counts are not available from
DPW, developers must provide new counts with their traffic studies.
(3) DPW may develop guidelines to be used to determine whether or not counts are acceptable and a
standard format for counts, including a tabular format.
4220.070 Trip Distributions and Assignments
Adopted: 1/1/03, First Revision 10/11/04, Second Revision 12/9/07
(1) Trip distribution means applying the trip generation to the road system to forecast the number of new
vehicle trips on specific roads in the system. A "trip distribution" is a type of traffic analysis that estimates
the likely destinations of trips generated by a proposed development and the likely traffic routes to reach
those destinations. The result of this analysis is a map or list indicating what number or percentage of
trips from the proposed development are added to the development's road system, including the number
or percentage of trips added to individual traffic movements on arterial units and/or at intersections. The
analysis provides a set threshold, consisting of a predefined number or percentage of trips below which
no attempt is made to further distribute the trips onto the road system.
