ESNW reviewed the referenced documents and visited the site to <br /> observe site conditions. If buildings will incorporate crawl spaces rather than slab-on-grade, in <br /> our opinion, a crawl space drain system will provide adequate drainage in lieu of perimeter footing <br /> drains. The crawl space drain must provide positive drainage to an appropriate outlet. If footing <br /> drains are not installed, we recommend backfilling footings with a relatively impermeable soil. <br /> We trust this letter meets your current needs. If you have any questions or if additional <br /> information is needed, please call. <br /> Sincerely, <br /> EARTH SOLUTIONS NW, LLC <br /> �l T W <br /> WA <br /> FEB 0 5 2024 <br /> 'q 53803 <br /> po�FS�F_1S7ERE�G\�� CITY OF FVERETT <br /> s/ONA\_ Permit Services <br /> 11/07/2023 <br /> Henry T.
