1. PROJECT DESCRIPTION
& Street address(ifknawn): 24223 76th, Ave. W - Edmonds, WA 98026
b. Location: East of 76th Ave_ W. approximately 4551 north of the intersection with SR104.
(Attach a vicinity map and site plan.)
c_ Specify existing land use: 3 single-family residences
d. Specify proposed type and size of development: 8 single-family residences
e. When will the project begin construction and when will it he completed? 2009-10
f Define proposed access locations: Access will be from a new public road that will connect to
76th Ave. W.
g. Define proposed sight distance at Site egress locations: Good: 76th Ave. W. is straight & topography
does not create blind spots.

S. TRAFFIC VOLUMES N/A Project is under 25 PHT.
a_ Describe existing ADT and peak -hour counts, including turning xnoverrzents, on street adjacent to and
directly impacted by the project
b_ Describe the estimated ADT and peak -hour counts, including turning movements, the year the project is
fully open (with and without project traffic).
c. Describe the estimated ADT and peak -hour taunts, including turning movements, five years after the
project has been fully open (with and without project traffic).
d. State annual background traffic growth factor and source:
5. LEVEL OF SERVICE ANALYSIS N/A Project is under 2s PHT.
Summarize Level of Service Analysis below and attach supporting LOS analysis documentation. Provide
the following documentation for each arterial street or arterial intersection impacted by ten or more peak -
hour trips. Other City -planned developments must also be factored into the LOS calculations.

7. NUTIGATION RECOMMMATIONS
State recommended measures and fees required to mitigate project specific traffic impacts. Traffic impact
fee shall be calculated from the Edmonds Road Impact Fee Rate Study Table 4 (attached) and as identified
in ECDC 18.82.120, except as otherwise provided for independent fee calculations in ECDC 18.82.130.
Existing use: 3x SFR- 3 x $840.72 = $2,522.16
Proposed use: 8x SFR- 8 x $840.72 = X56,725.76
Net mitigation rernzirement: $4,203.60
