. , ( � <br /> b) The foundation of the structures are over native stable soils. Thosa must bn at least 2000psf bearing <br /> capacity. This bearing is anly acceptable for what is described as a medium dense to dense soils. <br /> Descriptfon is provided in the sofls logs in the geotech�ical rep�R. Care must be undertaken with the area of <br /> test pit#2 on lot 5, the faoting depth to be detertnine below the black layer. <br /> c) A foundaHon setback must be maintained to avoid future problems. The setback is recommended to be a <br /> minimum of 8 feet from the face of the foundation to the face of the slopes. <br /> d) All the foundation to be fitted with adequate foundation drain which to be directed to daylfght at locations about <br /> 16"inches below the foundation leval. <br /> e) The roof runotf must be controlled, collected and directed to a public stortn system or an on-site adequately <br /> engineered system. <br /> � The alignment and design of the road and driveways must be in compliance of the geotechnical report, and <br /> also thely drainage. <br /> g) The erosion and sedimentntion probiems may be avoided by complying with lhe geotechnical report <br /> recommendations,during and post-construcNon. <br /> 2. The site steep slopes were found to be relatively heavily vegetated with native, upland vegetation <br /> types. Trees found were in general, dominantly mature Fir and other evergreen such as Alder and <br /> Hemlock, with dense covering and undergrowth. This consists of Salal, various native Berries and <br /> Fems. The site was found to be dry and well drained, with no signs or evidenced of ground water <br /> seepage or water plant loving species. <br /> Also no signs of previous ground movement, as would be evidenced by sca►ps, toppled or leaning <br /> trees, could be found on site. The parcel appears to be stable and we know of no historical <br /> landslide events in the immediate area. <br /> Some mottling was found in the test pits which indicated that the site soils contains at depth a more <br /> impervious layers which are poorly draining soils. Water is perched above the very slowly <br /> permeable, weakly cemented, compact part of the subtratum only for short periods. It flows on the <br /> top of this dense layer to s��ep on lower poRions of these moderately steep slopes. The water level <br /> will fluctuate depending on the time of the year and the amount of runoff, which causes the <br /> observed mottling. <br /> 3. During wnstruction, erosion and sedimenfation recommendations as per the geotechnical <br /> report must ba comalied with, see "erosion control and drainage" sections. Silt fences, <br /> temporary and permanent side cuts and adequate drainage for all impervious areas are <br /> issues necessary to the site stability. Roof and road drainage to be engineered. We <br /> believe that the report has the necessary requirements to assure the integrity of the site. <br /> 4.. The report recommends the following; <br /> a) As per "Site vegetation removal"section, only the necessary removal are allowad. Those are the areas of <br /> development. <br /> b) All the surround(ng slopes to be vegetated and maintained professionaily. <br /> c) The temporary culs to the foundation to be minimized to the least possible. <br /> d) Temporary side cuts for the foundation and the road to be as per the report recommendations. <br /> e) Erosion and sedimentation during construction to be prevented as per the report recommendations. <br /> 5. The proposal will be consistent with the purNose and provisions of this Ordinance if the <br /> applicant complies with all conditions of approval. <br />
