During review of the subject submittal, it was found that the following information, corrections, or
clarifications would need to be addressed. All Handouts referred to in these comments can be accessed at
our website: www.ci.edmonds.wa.us under City Government / Development Services Department /
Engineering Division then scroll down to Handouts:
1.Please add proposed erosion and sediment control measures to large site plan. It is difficult to discern
which line is which on the smaller plan. Please use a line with “x”s to show the proposed length and
location of silt fences.
2.Add to impervious surface calculations all existing impervious surface to be removed and the year it was
built.
3.Sidewalk Replacement Requirements:
Please show existing curb, sidewalk, and street on site plan. Show current curb cut.
At minimum, the curb, gutter and sidewalk will need to be replaced per City of Edmonds standards
from the expansion joint east of water meter to the expansion joint west of utility pole.
For remaining area of sidewalk please provide elevations for inside edge of sidewalk and
corresponding top of curb elevation at 1ft intervals to confirm cross-slope is 2% or less as required
per ADA Accessibility Guidelines.
4.Grading:
Please provide large size grading plan. Show existing and proposed topo lines in different line types
for clarity. Show grading in alley too, if any.
A site visit showed rear garage with relatively level floor. Plans appear to show a slope in that area,
please clarify.
Site visit also showed a considerable amount of grading would need to be done to bring the yard level
or near level with garage area and alley. Please revisit grading calculations for accuracy.
Please note bottom of footing(BOF) elevation on site plan so grading calculations can be verified.
5.Please show where proposed driveway entrance from alley begins and ends. Please note actual width.
6.Please add the following information to the site plan regarding the alley; surface type (paved, gravel..),
width of alley, show any other driveways or accesses across from this property or directly next door.
7.Provide specifications for grasscrete intended for driveway. City of Edmonds does allow some types of
permeable surfaces but not all kinds currently on the market are approved.
