Thc native soils underlying <br /> the site consist of inedium dense to dense glacial out���ash sand, and are suitable for <br /> com�entional residential foundation dcsign and construction procedures. <br /> "I'he steep slope ���ithin the ���cstern part of Ute site is stceper than 40 percent and is <br /> underlain by glacial adv�nce ouhvash sand (Qva). and it thereforc meets the City of Gverett <br /> criteria for a geologically hazardous arca, bo!h as a landslide hazard area and an erosion <br /> hazard 1rea. The top of the�10 percent slope is�pprosimatel��shown on Pigure 2. I3ased on <br /> !hc indinatiun ofthc slope and the character ofthc soils underlying the slope it is our opinion <br /> that tbis stcep slopc is pmsently stable. but thnt it is susceptible to erosion or shallow debris <br /> slides if disturbed by construction or other activities. <br /> Thc proposed addition is located approximately 4� fcet or more from the top of the steep <br /> slope,and is on the opposite side of thc esisting housc Gom thc slope. It is our opinion that <br /> this distancc and Ioc�tion is sufficicnt to avoid impacts to the geologically hazardous ama <br /> and that no eeologic hazards�vill result from the proposed de��elopment either within the site <br /> or on am- adjacent propertics. <br /> CLOSURE <br /> 'I�hc scr��iccs describcd in this report ��ere prepared imder the responsiblc charge of <br /> Don.�id �v. �r����,s, a geologist as defined by GMC 19.4. Dr. Tubbs understands the <br /> reyuirements of the current Geologicnlly Flazardous Areas Chapter GMC 19.37.080 and the <br /> dcfinitions of th� applicaUlc tcrms containcd within EMC 19.4. Dr. Tubbs personally <br /> perfonned a gcological asscssment,conducted a field im�estigation,and researched historical <br /> records on or in the vicinity of the above referenced sitc. ln Dr. Tubbs' opinion the scopc <br /> of ser��ices completed for this projcct is adequate to meet the requirements of the DepaRment <br /> oC Planning and Comnumity De��clopmenL Dr. Tubbs has concluded the proposed <br /> development ���ill avoid impacts to the eeologically hazardous arPas and that no geologic <br /> hazards will result from the proposed devclopment either within the sitc or on an)'adjacent <br /> propertics. <br /> This report has bcen prepared Cor Swtt Pcarson for his use in planning and design for the <br /> proposed devclopmenL Descriptions of subsurface conditions relati��e to foundntion support <br /> mid other aspects of the proposed dcvelopmcnt are based on surface obsen�ations and <br /> subsurfacc esplorations.
