GEOTECHNIC/�L ENGINEERING STUDY Susan and Thomas Zakos E-10138 Auyust 20, 2002 Page 9 If slopes of this inclination, or flatter, cannot be censtructed, temporary shoring may be necessary. Shoring will lielp protect against slope or excavation collapse, and will provide protection to workers in the excavation. If temporary shoring is required, we will be available to provide slioring design criteria. Permanent cut and !ili slopes sliould be inclined no s:eeper tlian 2H:1 V. Cut slopes sl�ould be observed by ECI during excavation to varify that conditions are as anticipated. Suppiementary recommendatfons can tfien be developed, if needed, to improve stability, includin� (lattening of slopes or installation of surface or subsurface drains. Permanently exposed slopes should be seeded with an appropriate species of v�getation to reduce erosion and improve stabilit�; uf the surficial layer of scil. Site Drainaqe As part of the site stabilization process. potential sources of surface or near surface water around the perimeter of the residence should be intercepted and diverted, Permanent grades sliould be establislied to direct surface water away from tlie existing residence and top cf slope toward an approved catchment area. Final site grades must allow for drainaye away from slopes and existing and proposed structures. The grou�d should be sloped at a gradient of 3 percent for a distance of a; least ten (10) feet away from residence deck supports, and retainin, wall. LIMITATIONS This report has been prepared for spec ric applicatio i to this project only and in a manner consistent with that Ievel of care and skill ordinarily exercised by other members of ti+e profession currently practicing under similar conditions in this area for the exclusive use of Susan and Thomas Zakos and their representatives. No warranty, expressed or implied, is made. This report, in its entirety, should be induded in the project contract do�uments for the intormation ot the con:ractor. Our recommendations and conclusions are ba�ed on tfie site materials observed, selective laboratory testing and engineering analyses, and our experience and engineering judgment. The conclusions and recommendations are professional opinions de!ived in a manner COI1JIJtent �vitli tf�at Icvel of care and ekill ordinarily exerci�ed by other members of the profession c.irrently practicing under similar conditions in this area.
