Subject: Bridge Animal Referral Center Trip Generation and Impact Fee
This memorandum summarizes the trip generation forecast and traffic impact fee estimate for the
proposed Bridge Animal Referral Center. The project site is located at 8401 Main Street in
Edmonds, Washington as shown in Figure 1. The project would generally maintain the same
building structure while constructing internal tenant improvements. The previous health and fitness
club occupied 16,302 square feet of the building will be replaced by a veterinary clinic occupying
9,967 square feet. The remaining 6,335 square feet that is owned by the veterinary clinic is
planned for later improvement and will remain vacant until a later date. No changes will be made
to the site plan or access driveways located on Main Street and 84th Avenue SW.

Trip Generation
Based on trip generation rates found in Institute of Transportation Engineer's Trip Generation
Manual (9th Edition), Table 1 summarizes the trip generation for the proposed and existing land
use. Detailed trip generation calculations are provided in Attachment A. Note that Trip Generation
does not provide a daily trip generation for the Veterinary Clinic land use. Daily trips for this use
were estimated by factoring daily and weekday PM peak hour trip rates for the Medical -Dental
Office land use,' as the medical office land use provides services similar to the proposed
veterinary clinic (human vs. animal).
' Medical -Dental Office (LU #720): weekday daily = 36.13 trips per 1,000 square feet, weekday
PM peak hour = 3.57 per 1,000 square feet.

1. Trip Generation rates based on ITE Trip Generation Manual (9th Edition).
2. No daily trip rate available for LU #640. Daily trips generated estimated
by factoring weekday PM peak hour and weekday daily
trip
generation rates for the Medical -Dental Office (LU#720).
As shown in the table, the proposed 9,967 square feet of veterinary clinic is forecast to generate
480 weekday daily trips, with 41 during the AM peak hour and 47 during the PM peak hour. When
taking credit for the vacation of all 16,302 square feet of the health/fitness club, the clinic is
forecast to decrease vehicle trips by -60 net new daily trips, increase AM peak hour trips by 18 net
new trips, and decrease PM peak hour trips by -11 vehicles.
Impact Fee
Impact fee calculations were based on information found in the City of Edmonds Traffic Impact
Analysis Requirements and 2009 Impact Fee Rate Table. The impact fee rate for the veterinary
clinic is based on the weekday PM peak hour trip generation rates published in Trip Generation
and the Trip Length Factor for the Medical Office land use in the impact fee table as it provides
medical services similar to the proposed veterinary clinic. Table 2 summarizes the calculated
impact fee rate for the proposed veterinary clinic and also provides information for the existing
Health/Fitness Club use.

1. ITE Trip Generation Manual (9th Edition).
2. Veterinary Clinic not available in 2009 Impact Fee Rate Table, %new trips and trip length factor rates for Medical Office (#720) were
used.
As shown in the table, after adjusting for the new trip percentage factors and trip length factors,
the impact fee for the veterinary clinic is calculated to be $5.21 per square foot while the Health
Club fee rate is provided in the City's fee table at $2.78 per square foot. Based on the planned
tenant improvements of 9,788 square feet, the veterinary clinic traffic impact fee is estimated to be
$51,928.07 while the existing 16,302 square feet of Health Club fee is estimated at $45,319.56.
With credit for the existing use, the estimated fee for the proposed project is $6,608.51.
