Re: [External] BLRE-07-22-7707 - SCIB LLC, Lot 283,378 Blue Heron Vista
Team,
The deck members such as the diagonal brace may all be treated. The decks should be around 30" over final grade so I don't think the deck framing would need
to be treated. No wood is ín direct contact with the concrete as the custom stee.l buckets provide a separation. WE can make the back plate of the bucket l-"
thick steel if we need to get a 1" standoff from the concrete, but I was undgr the impression that that requirement was only for post bases that would be subject
to standing water which ís not the case that we have being fastened to a vertical wall. Please let me know if this works and I can issue a updated set if required'
Thanks,
Mike Arbaney

Hello Luke, Dan, James, Mike and Teammates:
I am finishing the initial review for Lot 283 and have the following comments and requested corrections
L. TheproposedhomedesignforLotzsS-specifícallytheNEcornerofthebuildingexteriorwall with"elevatedrearporch"projectionsand
SW corner of attached garage with exterior wall and roof projections - do need to be REVISED modestly to comply with 2015 lnternational
Residential Code Table R302.1(1) exterior walls. Provide L-hour rated fire-resistance rated assembly details for the exterior walls where
located less than 5 feet to a property line. Provide fire-resístance rated assembly details for projections located greater or equal to 2 feet
and less than 5 ft (or supply supplemental details demonstrating roofs will conform withþotnotes a ond b) of the adopted Table
R302.1(L). Be aware projections less than 2 ft to property lot lines are prohibited under the lRC, and original plan detaíls in those instances
will need to be amended or the building location shifted slightly. Due to proximity to property lot lines on all sides of the home, it ís
anticipated that some walls and projections will require some amount of fire-resistance protection.
2. Structural Sheet 5L.0 Detail 8 Deck Framing, appears to include DF#L framing members in close contact with concrete and earth below. We
are concerned with exposure to concrete and grade. Please revíew 2015 international Residential Code, Section R317 Protection of
Wood and Wood Based Products against Decay. Specifically R3L7. ltern #2. Demonstrate how wood will be protected or have structural
engineer specify materialthat is naturally resistance such as heartwood of decay resistant redwood, cedars, black locust or black
walnut. We are happy to re-evaluate with further information or narrative.
