<br /> Dear Mr. Bargreen: � ��,��(M^�� r� - ���� '� -
<br /> i I �r.
<br /> Last month, we met in the ficld to discuss your concerns regarding reservoir#4 leakage.
<br /> Specifically., you fcit that watcr that Icaks from reservoir#4 contributes to slope stability
<br /> problems on your property. You suggested that the City install a liner in reservoir#4 to reduce
<br /> leakage.
<br /> Since wc discussed this in the field, [have evaluatcd the role of reservoir#4 leakage in reducing
<br /> the siability of the slope on your property. My evaluation included analysis of: reservoir#4 as-
<br /> built drawings, topographic maps and reservoir leakage records.
<br /> The conclusions I have reached are:
<br /> ( , t)'Che underdrain system that was installed when resen�oir#4 was originally constructed
<br /> , �n 1953 continues to collect reservoir Icakage and function properly.
<br /> i � 6 , r�, ' .
<br /> . i� ''' � 2)Thc underdrain systcm drains to a pipe that is tightlined to thc bay. Thercfore, any
<br /> �''� i watcr collected b the underdrain s titcm does not flow as roundwatcr to oar ro rt
