Harter — 9630 2381h St SW
Engineering has reviewed the conditional use application for the Harter residence at 9630 —
2381h St SW. The information provided is consistent with Title 18 Edmonds Community
Development Code & Engineering standards. The applicant has demonstrated that the three
required parking stalls can be provided on site.
Please include the following conditions in the staff report.
1. Plans indicate that improvements associated with the Accessory Dwelling Unit will create
new impervious surface areas in excess of 2000 sq. ft. City code requires stormwater
management (SWM) to be provided when impervious surface areas created after 1977
exceed 2000sf. The building permit submitall will need to address this requirement. The
use of Low Impact Development Techniques is encouraged by the City wherever feasible.
This could include rain gardens, pervious pavement, etc. Engineering Division staff
would be happy to discuss this further with the applicant.
2. If the proposed retaining wall will support a surcharge, design and calculations submitted
with the building permit will need to be prepared by a licensed engineer.
Thank you.
City of Edmonds
