Drainage/Detention Review comments from Storm Water Engineer, Jerry Shuster:
30.The outfall for the detention system is in the stream buffer and likely within the ordinary high water
mark of the stream. This current arrangement would necessitate a permit from the state Dept. of Fish &
Wildlife (Hydraulic Project Approval or HPA). Rather than a direct outfall into the creek the applicant
should consider a dispersion or infiltration trench outside of the buffer connected to the detention system
outfall.
Please refer to the attached document titled ‘Stormwater Management Review Checklist’ for review
comments from Jerry Shuster.
Please resubmit 3 copies of the revised plans/documents to a Development Services Coordinator. Please
contact me at 425-771-0220 if you have specific questions regarding these plan corrections.
