2)Please note that the entire driveway from edge of roadway to structure must be included in the
impervious surface calculations. Please revise plans accordingly.
3)The water runoff from the driveway (portion on private property) must be collected and outfall to the
detention system. Please show how the runoff will be collected.
4)Per the architectuals, it appears that the deck (south side of building) is impervious (either it’s covered
or the deck is solid).
a.Please note on the plans if the deck is impervious.
b.If the deck is pervious, please note what material is below the deck (i.e landscape) and what the
deck is made of.
c.Please revise the imerperviuos surface calculations accordingly.
5)Please show the footing drains connected to the outfall line of the detention system. If you propose to
outfall the footing drains to an underground system, please provide approval from a Geotechnical
Engineer.

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.
CHANGE IN USE
Fee for prior use shall be based on fee established at the time the prior use was permitted. If the
previous use was permitted prior to the adoption of Ordinance 3516 (effective date: 09/12/04),
the 2004 ECDC 18.82.120 impact fee shall be used.
