Comments completed by Jerry Shuster, City of Edmonds Stormwater Engineering Program Mgr
12) 12/03/08 - With the information provided it is still not clear whether any overflow from the
portion of the trench along the west property line will impact the adjacent property. Also, the
Trench Section detail on sheet P3 indicates the bottom of the trench is proposed to be 2 feet 4
inches below grade, but it is not clear based on this information alone whether the infiltrated
water from the proposed trench will impact the property to the west.
Please provide adequate topography and show the flow paths for both the overflow and the
infiltrated water from the trench towards the west in relation to the adjacent property. The
overflow water must not flow onto the neighboring property and pool or otherwise impact the
property. You must show that the infiltrated water passes under the foundation of the neighbor to
the west or otherwise does not impact the property. Adjust the drainage system as as necessary.
The next submittal must clearly show that overflow and infiltrated water from the system will not
impact the adjacent property to the west. There is also the option of discharging the detention
tank to a new catch basin in the right-of-way and then connecting to the City storm system further
west on Alder St.
Also, the Trench Section detail on Sheet P3 shows a 2 foot-wide trench. The profile on Sheet P3 as
well as the plan view on sheet P2 calls out a 2.5'x6' & 3' trench. It appears from sheet P2 that an
L-shaped trench that is 6 feet long (2.5 feet wide) along the west property boundary and an
additional 3 feet long (2.5 feet wide) along the southern site boundary is proposed. Please, revise
the trench detail on sheet P3 to reflect a 2.5 foot wide trench bottom and a detail showing how the
perforated pipe is going to be connected at a 90 degree angle within the L-shaped trench.
11/06/08 Previous Comment –
Comment was partially addressed. Please provide a detail for the
spreader trench (detail 3/P3 was referenced but not provided). Ensure that the discharge from the
trench does not impact the adjacent property to the west. If you have any questions please contact
Jerry Shuster, Stormwater Engineer Program Manager (425-771-0220 ext 1323)
7/18/08 Previous Comment:
Please relocate spreader trench onto south property line so if system
overflows the overflow will go into the right of way.
Please resubmit 3 copies of the revised site drawings and associated documents with a written response to
each item to an Engineering Technician. Please contact me at 425-771-0220 ext 1321 or by e-mail at
collinsj@ci.edmonds.wa.us if you have specific questions regarding these plan corrections.
