I <br /> . , <br /> 3. The proposed method of construction will reduce erosion potential, landslide and <br /> seismic hazard potential, and will improve or not adversely affect the stabiliry of <br /> slopes; and <br /> 4. The proposal uses construction techniques which minimize disruption of existing <br /> topography and natural vegetation; and <br /> 5. The proposal is consistent with the purposes and provisions of this Ordfnance; <br /> and <br /> 6. The proposal mitigates all impacts identified in the geotechnical report; and <br /> 7. All utilities and access roads or driveways to and within the site be located so as <br /> to require the minimum amount of modification to slopes, vegetation or <br /> geologically hazardous areas. <br /> The Planning Director's conclusions are as follows: <br /> 1. The proposed development wlll not create a hazard to the subject properry, <br /> surrounding propertles or r/ghts-o%way, erosion or sedlmentation to of/-sJfe <br /> properfies or bodles o/water. The new lawn area atop the retained backfill <br /> behind the wall will act to slow down stormwater flows across the previously <br /> sloping area, allowing sediment to settle out and be retained onsite. The reclaimed <br /> area will also help to intercept stormwater that previously flowed over the face of <br /> the slope at this location, lhereby improving stability cond(Hons in the bluft soils and <br /> reducing the likelihood of sediment transport offsite (BEK Engineering 9/12/01). <br /> The retaining wall which was erected on site, runs along the top of bank on the <br /> rear of the property, away from other properties and right-oF-ways. <br /> 2. The proposa/addresses the exlsting geologlcal constraints of the slte, <br /> inc/uding an assessment o/solls and hydrology. This project was evaluated <br /> by a geotechnical consultant after it was built. Therefore, the evaluatlon is made <br /> from the review o(photos of the project under constructfon, experience with similar <br /> projects, knowledge o(area geology, and a visit to the sfte. P�o subsuriace <br /> explorations were performed on site, nor observation of the construction periormed <br /> on site (BEK Engineering 9/12/01). <br /> The geological constraints to site development appear to be related to the <br /> proximity o(the adjacent slope. The retaining wall takes into account the nearby <br /> slope by providing tieback anchors on the support posts, so that less lateral <br /> pressure is applied to the soils making up the slope. The glacially- <br /> overconsolidated native soils present in the South Everett area are generally <br /> suitable for bearing support of the loads applied by a 2 to 4-foot high wall and <br /> associat�d backfill. Near-surface hydrology of the immediate area would be <br /> controlled by the change in elevation through the axis of the adjacent wooded <br /> swale,which we understand does not support standing or running water. The <br /> retaining wall should not change the local hydrology, other than to slow local <br />� <br />
