Mitch,
I was looking over the additional information you provided. Everything looks good except for a few small issues:
- Permit Application
o Section IV, 8 —The percent impervious area should be calculated as the total post -construction
impervious area on -site (47,307 sf per Supplement-EZ) divided by the total project area (4.77 ac).
o Section IV, 10 — All of the areas should be shown in square feet, not acres.
o Section IV, 10—The Proposed Impervious Area value should be the Total value from the Impervious
Surface Area table.
o Section IV, 10—The Percent Impervious Area value should be the Proposed Impervious Area divided by
the Total Drainage Area.
- Supplement-EZ
o Section V — The hard copy of the Supplement-EZ form needs an original signature (No photocopies).
o Supplement-EZ Drainage Area Page
■ Line 16 — Please include the Percent BUA ( % BUA = Line 5 / drainage area)
o Supplement-EZ Sand Filter Page
■ Line 8 — Should be "Yes" based on plans (A riser structure and emergency spillway are provided).
■ Line 22 — Should be "Yes" based on plans (The sand filter store storms up to the 25-year storm).
■ Line 31—The bottom of the sand chamber is the elevation of the lowest point of the sand
chamber. This is used for verifying Sand Filter MDC 1.
■ Line 33 —This depth should also include the sand, gravel, and underdrain portion of the
chamber.
Please submit 2 corrected permit applications and a corrected, original Supplement-EZ form.
Since these are really minor things, once I get the hard copies and the documents are uploaded to Laserfiche (Provided
everything is still in order), we can issue the permit without doing another 30+ day review period.

Mr. Latham,
Yes, you are supposed to complete both drainage area columns. The entire site column takes into account the entire
project site, there is no need to remove the area draining to the proposed SCM.

Please feel free to contact me if you have any further questions.

Good Afternoon Mr. Farkas: Based upon your RFI dated July 31st, I am working on the additional information for the
referenced project.
Item 6 request the submission of Supplement EZ form. For the drainage area portion on the second page of the
spreadsheet, there are two
columns labeled "Entire Site" and "l
Can you please clarify if I am supposed to complete both columns? If I am doing both columns, do I complete the
"Entire Site" based upon
the entire site, or the remaining portion of the site that is not draining to SCM 1.
Thanks for your help with this.
