500 LAUREL DR 2016-01-01 MF Import

, ( the Planning Direc[or to authorize the alteration of a slope or its buffer if ne approves a geotechnical report, which demonstrates that: 1. the proposed development will not create a hazard to the subject properry, surrounding properties or rights-of-way, erosion or sedimentation to off-site propertiec or bodies of water; and 2. [he proposal addresses the existing geological constraints of the site, including an assessment of soils and hydrology; and 3.. Uie proposed metl�od of construction will reduce erosion potential, landslide and seismic hazard potential, and •,vill improve ar not adversely affect the stabiliry of slopes; and 4. the proposal uses construction techniques which minimize disruption of existing topography and natural vegetation; and 5. the proposal is consistent with the purposes and provisions of this Ordinance; and 6. the proposal mitiga[es all impacts identified in the geotechnical reporr, and 7. all utilities and access roads or driveways to and within the site be located so as to require the minimum amount of modification to slopes, vegetation or geologically hazardous areas. CONCLUSIONS: The following cor.:lusions are based upon tlte findings nf the geotechnical report prepared by CGO. 1. The proposed development should nut adversely impact the slope if the recommendations of the geotechnical report are follo�ved. The final design plans sl�all be revie�ved by CEO to insure that the earthwork, foundation, and drai��age have been properly implemented in the buildir.g plans. 2. An exploratory boring just iuside the footprint of the proposed addition demnnstrates that the slope is composed of inedium den>e surficial and shallow silry sand soii and hard, finer grained, silry soil a. greater depths. There was no surface water visible. Groundwater seepage was encountered at a depNi of approximately 16 feet. The seepage is c�nsidered the result of in6ltration of precipitation into the ground upgrade from this site. The well established groundwater level is proUably 120 feet below the existing site. �
