th
Retaining wall at 204 7 Ave N
On behalf of the Planning Division, I have reviewed the above building permit application. During review of the
subject submittal, it was found that the following information, corrections, or clarifications need to be addressed.
Please respond to the following items, so that I can complete my review:
Retaining wall and setbacks
1.: The subject property is zoned RS-6 (Single-family residential). Setbacks for
RS-6 zoned property are outlined in Edmonds Community Development Code (ECDC) 16.20.030 and are as
follows:
Zone Minimum Street Minimum Side Setback Minimum Rear
SetbackSetback
RS-6 20 feet 5 feet 15 feet
The southern property boundary of this parcel fronts Bell Street and is lot line from which the 20 foot street
setback is measured. Retaining walls over three feet in height must meet zoning setbacks. The application
materials indicate the retaining wall will be 4 feet in height and also shows the retaining wall within the 20 foot
street setback. Please revise the application so the retaining wall is three feet or less in height, or locate the
retaining wall outside of the zoning setbacks.
Geotechnical Report Requirements
2.: The geotechnical report dated October 5, 2009 prepared by Ricky Wang
of the Riley Group does not meet the minimum requirements for geotechnical reports as detailed in the City of
Edmonds critical area regulations. The minimum requirements for critical area reports are spelled out in ECDC
23.40.090 (http://www.mrsc.org/mc/edmonds/edmonds23/edmonds2340.html#23.40.090), and the special study
and report requirements for geologically hazardous areas are detailed in ECDC 23.80.050
(http://www.mrsc.org/mc/edmonds/edmonds23/edmonds2380.html#23.80.050). Additionally, the retaining will
be placed within the landslide hazard area and/or its buffer, and pursuant to ECDC 23.80.070.A.1
(http://www.mrsc.org/mc/edmonds/edmonds23/edmonds2380.html#23.80.070) the report must verify the
reduced buffer will adequately protect the proposed development, adjacent developments and uses and the
subject critical area. Also pursuant to ECDC 23.80.070.A.2, the report must contain a hazardous analysis that
certifies a) The development will not increase surface water discharge or sedimentation to adjacent properties
beyond predevelopment conditions; b) The development will not decrease slope stability on adjacent properties;
and c) Such alterations will not adversely impact other critical areas. Please update the geotechnical report so it
.
addresses the elements outlined above
Please make all submittals to a Development Services Permit Coordinator, Monday through Friday, 8:00 am 4:30
pm. If you have any questions, feel free to contact me at 425.771.0220 ext 1223.
