~L~I r VLV I N C O R v O R A 1 E D 2. The installation of permanently-pressurized irrigation systems should be restricted to avoid any detrimental saturation of the slope area. Resulting damage to the slope could adversely affect the stability of a house constructed upon the adjacent Lot and/or houses on other Lots. 3. Each Lot must be graded in accordance with the approved lot development plans. Prior to any regrading on a Lot, the Lot owner's State of California licensed geotechnical engineer or certified engineering geologist will review Lot __ improvements. The geotechnical engineer will provide criteria to the GRAD geotechnical engineer for Lot grading, foundation design, surface and subsurface drainage and retaining wall design. The geotechnical consultant employed by the Lot owner shall observe excavations and provide an "as-built" report of the conditions _ encountered and mitigation measures taken. This report shall go to the GHAD consultant. The GHAD engineer will provide recommendations as required. The geotechnical engineer should also review and be aware of any prior improvements on the Lot and in the vicinity including any slope repairs and subdrainage systems - installed during the initial subdivision grading, or in some cases, by the development of adjacent Lots. Subsurface drainage systems were installed during construction of the subdivision. - The purpose of subdrainage systems is to provide a means by which subterranean waters can be dissipated to avoid any detrimental saturation of the soils. It is important that the integrity of the subsurface drainage systems be maintained. - 4. Surface water drainage is typically to the Lot front, Lot rear or Lot side, as the case may be, for ultimate off-site disposal. Such drainage is accomplished by positive grading and by cutting drainage swales or channels on the surface of the Lot. No 4291-W2 July 17, 1997 _ Revised October 9, 1997 Revised October 22, 1997 t ~
