Main Street, Suite 104 Aspen, Colorado 81611 voice: 970.544.4851 email:LAM@MenendezArchitects.com July 30, 2018 Mr. Stephen Kanipe Community Development Department City of Aspen 201 N. Mill Street Aspen, CO 81611 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. 11/27/2018 This modification is acceptable as it meets the intent of 2015 IBC section 104.11 and provides equivalent protection. 02/15/2019
