9/21/11 Comment -Please showall private and public easements.
10/25/11 –Comment was partially addressed. The total regulated area impervious area should

be the sum of the replaced and new. Areas mitigated by low impact development means that the
water does not enter the city storm system. Since the raingarden is piped to the pond which is
Page 3of 7
then released to the city storm system the rain garden is not considered LID. Therefore #7 in
the chart should be 0. Please revise the chart accordingly.
9/21/11 Comment -Please revise the impervious surface chart to include all areas of impervious
surfaces that were constructed after 1977 as new. When you deductthearea that is being mitigated by
an existing stormwater management system from the total regulated impervious area, your amount of
regulated area notyet mitigated should equal 51,718 sqft. Please make sure to separatethe 51,718 sqft
into LID and conventional stormwater systems as directed in the impervious surface chart.

Review comments by Jerry Shuster, Stormwater Engineering Program Manager:Please contact
Jerry directly with any questions you may have related to the storm drainage report. Jerry can be
reached by email at shuster@ci.edmonds.wa.usor by phone at 425.771.0220.
For this permit I reviewed the following:
Swedish/Edmonds Hospital, Puget Sound Cancer Center, DrainageReport, dated August 2011,
KPFFConsulting Engineers.
Civil Plan sheets C-410, C-500, C-510, and sheets with referenced details.
Drainage Report
1.10/25/11 –Comment was partially addressed. The first part of the comment has been
satisfactorily addressed. It is unclear what area is considered the “bypass area”; it should be
delineated in Figure 3. It should also be noted if bypass area contains any pollution generating
impervious surface. If so it would need to be accounted for in the site’s treatment systems.
9/21/11 Comment -Section 2, page 2.This section should include a description the current drainage
system served by all parts of the site that are going to be redeveloped by the proposed project.A
drawing should show what areas are tributary to the existing vault.A second figure (under Section 3)
should show all areas of the proposed projects that are tributary to the various stormwater features
(rain garden, media filter, sand filter, and detention pond) and the bypass area.This information
should feed into the table on Sheet C-500 that has a tally of the various types of impervious surface
areas.
2.10/25/11 –Comment was not addressed satisfactorily. The CSWPPP appears to be written to
the2005 CSWGP. It needed to be written to the 2011 permit.
9/21/11 Comment -Section 3, page 3, Construction Stormwater Pollution Prevention Plan.
a)The site classifies as a Large Site Project.Large site projectsare required to have an
assessment of the erosion potential of the site.Please fill out the enclosed form and include
it the report as anappendix.
b)On page 3 of the report, discuss the results of the erosion potential scoring.
c)The Construction Stormwater Pollution Prevention Plan for the project that willbe submitted
totheDept. of Ecology should be included in the submittals to the City of Edmonds.Be sure
to sendthe Notice of Intent and write the plan to the most recent Ecology Construction
General Stormwater Permit (CSWGP), effective 1/1/2011. More information can be found at
http://www.ecy.wa.gov/programs/wq/stormwater/construction/permit.html.
