1564_001I August 31, 2021 Client: American Home Planners Project Address: 7003 I65"' PL SW Edmonds, WA Subject: Foundation Revision SDA Ref. #i9239 To whore this may concern: At the request of American Home Planners this office reviewed a foundation revision pertaining to this project. 'The original plan set specifies a 36x36x10" thick concrete footing. This new footing conflicts with an existinc= 39" tali x V wide stem wall and 16" uWe x 8" thick strip footing. The existing foundation is reported to be in a good condition with no cracking, spalling, or visible damage. See photo#i'. The point load at the new 36x36x10" thick footing is reported to be no greater than 11,232 lbf (L.L::=6733 .lbf & DL==4499 IM). The effective lerigth of'the existing footing is 7'-10" long via a 45-degree load distribution. The allowable soil bearing pressure is assumed to be 1,500 k,. F as permitted by the 20118 IBC. Therefore, the rnaximurn allowed point load located at the top of the existing stem wall is 15,600 IV. This maxinium load exceeds the reported load conditions. The existing stem and footing,, in the reported state, are deerned adequate to support the 1 1,232 IV point load. The contractor is responsible to verify the existing stem/footing conditions and communicate field discrepancies that contradict this report. Please contact this office if you have any questions concerning this letter, or for any other assistance. Sincerely, IEO VIWA " 34383 Chris Covington, P.E.
