<br /> Our tesponsE to tbis is that the language "ta the ext�ent feasible" is lauguage from the
<br /> preparer� af the City's EIR, not langtiage fram the applicant's cansultants. The leading
<br /> geoZogists in the Bay Area have reviewed and reparked an the propased development and
<br /> if tlie �ity Staff ar thc City has same quarrel vv�th or objectian to the findings and
<br /> opinians af those experts, th�n the City ar the Staff shauld present facts upon which to
<br /> base the�r abjectians, or upon which to found their cancerne.
