0 r� u Mr. Aaron Byrne Site Inspection 2421 Rockefeller Ave Everett, WA November 17, 2021 Page-4.3—• The purpose of underpinning the foundation is to support portions of the structure that has experienced some differential settlement. The underpinning piles are designed to support the structural loads in the immediate areas where they are placed and not to prevent uplift from soil heave. Maintaining uniform moisture around the foundation is very important. The landscape grades around the residence should be maintained to slope away from the residence where required. The landscape grades should slope away from the foundation at a minimum of/H per foot for six (6-0) feet. The top soil should extend a minimum of one (V-0) foot above the bottom of the grade beam and should not extend above four (4°) inches below the bottom of the siding. All new fill soil should be clayey sand with a minimum Plasticity Index (PI) of twenty-five (25). Watering the soil around the foundation is also important during dry periods to help maintain uniform moisture in the soil. This concludes this report. Observations made in this report pertain to the condition of the residence on the date of the inspection which is subject to change. No foundation warranty is expressed or implied by this report. If I can be of further assistance or should you have any questions about this report, please do not hesitate to contact me. Sincerely, L1� James Hogan, E.I.T. Darin Willis, P.E.
