GEO Group <br /> Northwest recommends the following measures to mitigate risks on the north-facing steep slope: <br /> • Avoid any activity that disturbs/alters the topography or vegetation that exists on the <br /> sloped areas. <br /> • Temporary stormwater drainage measures should be implemented as appropriate during <br /> construction of the proposed developments to minimize runoff onto or near the steep <br /> slope. <br /> • Fills, including yard waste and other debris, should not be placed onto the slope. This <br /> material could smother and kill existing vegetation on the slope,which help protect the <br /> slope from erosion and improve overall structural integrity of the soils. Also, the <br /> accumulated looser debris on the slope could migrate down the slope and become a <br /> landslide hazard. <br /> GEO Group Northwest appreciates the opportunity to provide geotechnical engineering services <br /> for this project.
