City of Edmonds Traffic Impact Analysis, GTC #07-354
Dear Mr. Gebert:
Gibson Traffic Consultants (GTC) has been retained to provide a traffic study for the
proposed Murphy Townhomes residential development in the City of Edmonds. This
study summarizes traffic generation, access sight distance and traffic impact fee
information per the City's 'guidelines for developments generating less than 25 peak -hour
trips. This study has been organized in the manner of the SEPA Traffic Impact
Requirements for the City of Edmonds.
11,13) AIMMSIMAI
The development is proposed to consist of 17 townhomes. There is an existing medical®
dental office on the site which will be removed and credited towards the developments
trips. The square footage for the existing building was obtained from the Snohomish
County Online Property Information website and it shows there to be 14,068 SF.
The development site is located at 20728 76"' Avenue W, Edmonds, Washington. A site
vicinity map has been included in Figure 1. The proposed residential development is
anticipated to begin construction in the Fall of 2008 with expected completion in the Fall
of 2009. The proposed site access is to be located opposite 20 g1h Street SW on the
property's southern property line.
TRIP GENERATION
Trip generation rates were obtained from the ITE Trip Generation, 7'I'Editimi 2003. The
following land uses were used to determine the number of trips that will be generated by
the development: Land use code (LUC) 230 townhome/condominium and LUC 720
medical -dental office. The average trip generation rates for each land use code were used
to determine the trips generated. The existing medical -dental office generates more trips

than will be generated by the 17 townhome units. The development will therefore result
in 409 ADT with 43 PM Peak -flour trips (S inbound/35 outbound) being removed
from the road system. A summary of the trip generation has been included in Table 1.
The trip generation calculations are included in the attachments.
SIGHT DISTANCE ANALYSIS
The development is proposing to have access onto 76t" Avenue W, along the south side
of the property, opposite of 208t" Street SW. Therefore, sight distance checks were
performed where the proposed access intersects with 76th Avenue W. The posted speed
limit along 76t" Avenue W and 20t" Street SW is 30 mph in the site vicinity. Based on
the American Association of State Highway and Transportation Officials (AASHTO)
sight distance requirements for a 30 mph posted speed limit, the required stopping sight
distance is 200 feet and the required entering sight distance is 335 feet. The stopping
sight distance was measured from the centerline of the roadway to an object 2 feet in
height from an assumed driver eye height of 3.5 feet. The entering sight distance was
measured from 10 feet back of the pavement at an assumed driver eye height of 3.5 feet
to another assumed driver eye height of 3.5 feet.
Where the proposed access intersects with 76t" Avenue W sight distances extend beyond
335 feet toward both the north and south and also to the east. The proposed
development accessing at the intersection of 76t" Avenue W and 208t" Street SW will
satisfy the safe stopping sight distance requirements per the City of Edmonds'
guidelines.
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 information in the table is based
on ITE Trip Generation, 6`h Edition (1997). The trip rate for the condominium/townhome
and medical office portion of the development was calculated on the information in the
newer ITE Trip Generation, 7`h Edition. (2003).
The existing medical -dental office is credited towards the developments mitigation
payment using the same mitigation fee methodology. With this credit, the development
would not be required to pay a traffic impact fee to the City of Edmonds since it will not
generate any new trips. The mitigation calculations have been summarized in Table 2.
