6.Please clarify/revise impervious surface calculations as follows:
What areas are included in the Pre-Developed area? Could this be labeled as Existing?
·
Please note the year in which the impervious areas were constructed.
It is assumed that all existing impervious areas drain to the detention system. If this is the
·
case, please note existing impervious areas to remain and existing areas to be removed so the
total of what drains to the detention system can easily be tracked.
Specifically state the total proposed impervious area.
·
It is assumed the Developed Impervious area total is the new total impervious area for the
·
site, including the existing impervious that is to remain plus the proposed impervious area. Is
this accurate? If so, please label as Total Impervious Area.
Please also note on the plans that the existing storm detention system was designed and
·
approved while under the jurisdiction of Snohomish County.
7.Indicate on plans where footing drains will connect to the storm system. Typically, footing
drains are required to connect to the outfall side of the storm detention system or a drywell is
provided on site.

9.At all storm structures, existing and new, please provide pipe size & invert elevations for
proposed pipe connections as well as existing pipe connections.
10.Please provide information regarding the existing storm water quality vault. In looking at the
asbuilt that was submitted with this permit application, the water quality vault contains compost
material at the bottom of the vault. Is this system still functioning as designed? What is the

quality vault. The spot elevation shown in this area is covering the pipe.
