Re: 1411 Crystal Lake Road, Valley Group/Smallwood House (Permit No. 0062-2018-
ARBK)
Dear Mr. Kanipe;
This letter serves to request approval for an alternative method of construction, as
permitted by IRC Section 104.11, for secondary drains or scuppers required by 2015 IPC
Section 1108.
This request applies to the section of roof that lies between Grid I to Grid Q and Grid 3 to
just south of Grid 11 (please refer to the Roof Plan on Sheet A-105). This area of roof
will have numerous drains that connect to exposed exterior downspouts directly below
each roof drain. There will be no internal pipes connecting roof drains. Each roof drain
has been designed to serve as an overflow drain for other drains on the same section of
roof.
There is never more than a 3.5” vertical rise in roof slope between any two drains with
most only having a rise of 2.5” before the water spills over to the next drain. The
structural engineer has designed the roof structure to support the weight of any water that
could accumulate, before draining to an adjoining drain.
The proposed solution meets the intent of the code by providing a secondary means of
drainage but in a way that is slightly different than the letter of the code.
Please contact me with any questions.
Sincerely,
Luis Menendez A.I.A.

This modification is acceptable as it meets the intent
of 2015 IBC section 104.11 and provides equivalent
protection.
