Rick,

I was looking over the additional information you provided on 11/5. Everything looks good except for a few small issues:
- There appears to be a discrepancy between the information in the table in Section IV, 10 of the Application and
the information in column 1 of the drainage area sheet of the Supplement-EZ Form.
o The “Proposed Impervious Area” line of the “Basin Information” table in Section IV, 10 should match the
“Total” line of the “Impervious Surface Area” table in Section IV, 10.
o The “% Impervious Area” line of the “Basin Information” table in Section IV, 10 should be drainage area
specific. For example, if the total impervious area within the drainage area is 9,320 sf and the total
drainage area is 10,333 sf, then the percent impervious area would be 90% (9,320 / 10,333 = 0.901 =
90%).
o The “On-site Buildings/Lots” line of the “Impervious Surface Area” table in Section IV, 10 should match
Line 10, “- Roof” of column 1 of the Supplement-EZ Form.
o The “Existing BUA” line of the “Impervious Surface Area” table in Section IV, 10 should match Line 13 of
column 1 of the Supplement-EZ Form.

- Please also correct the Supplement-EZ form as follows:
o Line 5 – This is the total BUA that will exist in proposed conditions. For the “Entire Site” column, the
value appears to be correct. For the drainage area “1” column, this line should have the total proposed
BUA within the drainage area to the facility (9,320)
o Line 7 – This is the increase in BUA. Based on the information in the SIA, the “Entire Site” value for this
line should be the difference between post-development and pre-development BUA for the entire site
(38,302 – 34,755). The drainage area “1” value for this line should be the increase in impervious area
within the drainage area to the facility. This value does not necessarily need to be the same as the entire
site column value and should not be negative.
o Line 10 – This is the increase in BUA, broken down by type. Based on the information in the SIA, the
“Entire Site” values for this line should add up to the difference between pre-development and post-
development BUA for the entire site (38,302 – 34,755). The drainage area “1” values for this line should
be the net increase in impervious area within the drainage area to the facility, broken down by type. The
items in line 10 should add up to line 7.
o Line 13 – The “Entire Site” value for this line appears to be filled out correctly. The drainage area “1”
value for this line should show the total existing BUA located within the drainage area to the facility.
o Line 15 – Since there is a net increase in the impervious area, do not use this line. If there was a net
decrease in the BUA, the decrease would be reported here.

Since these are really minor things, once I get the hard copies (Sheet 3 of the Application, signed Supplement-EZ form,
and anything else that may have changed from addressing these issues) and the documents are uploaded to Laserfiche
(Provided everything is still in order), we can issue the permit.

Let me know if you have any questions.
