ENGEO Nc.; Plan of ConSol, ~moine Prope~y, Pleasanton, California; September 16, 2~3; Project No. 4992.5.001.01. De~ ~. Jost: As requested, ENGEO is pleased to provide tNs proposal with fee estimates to initiate G~ monitoring of the ~moine Ranch propeny upon the City of Pleasanton, C~ifomia's acceptance of public improwments. We propose to initiate twice-a-ye~ site reconn~ssance to smisfy the monitoring mquiremenm of the G~ PI~ of Control (Reference 1). Prior to the ini6al monitoring ~vent, we will review previously published geotechnical repoms, geologic maps, and gading "as-builts" for ~e proj~t. To facilitate the review, we request that project-s~cific geotechnical repoms be made availabl~ to ENGEO. Meas of pmicul~ concern documented in the Plan of Control and any subsequently identified ~eas of concern will incoMorated into the site inspection sch~ule. Some of the items that will be addressed du6ng the monitoring events include: a reconn~ssance of co~on ~a cut slopes located adjacent to improvements; obse~ation of ~eas of ~own lan&lide rep~r undertaken during the mass grading operations; obse~ation of ~own readily accessible subdrain outlets installed during the mass grading; obse~ation of the lined surface drainage ditches and catch basin inlets for debris; ~d obse~ation of sel~ted curb and gutter ali~ments. We will also review ~eas of potential slope instability and surface rapture that were documented in e~lier geotechnical studies and that ~e located adjacent to existing improvements. We will provide the O~ anWor the owner of the ~moine Easement Area at least three calend~ days written notice or twenty-four hour personal or telephonic no~ce prior to our regul~ly-scheduled inspection ewnts. We propose to conduct two regul~ly-scheduled monitoring events and sub~t one annual monitoring repom for a fixed-fee of $900 per annum. We will conduct additional inspection events on an as-needed basis (e.g. within 48 houm after a significant rain event) for a fixed-fee of $900 per event, including We su~ repom. 2010 Crow Canyon Place · Sui'~e 250 · San Ramon, CA 94583-4634 · (925) 8609000 ° Fax (925) 866-0199 www. engeo.com
