You asked the City, in an October 28, 1997 letter, to describe <br /> the drainage and erosion control measures it had taken to prepare for the landfill for the wet <br /> weather season. <br /> The City responded, in a December 10, 1997 letter, describing its wet weather preparation <br /> measures. These included the following actions: <br /> regrading low areas (caused by settlement) to prevent ponding; <br /> compacting side slopes to help prevent erosion and; <br /> placing hay bales on slopes to further aid in preventing erosion. <br /> Because of these preparations very little ponding and erosion occurred this wet weather season. <br /> However, leachate seeps did develop along the north has re elNeditvvi�its normalto the luge of <br /> ra rainfall <br /> rainfall the "EI Nino" storms produced this year. (Stockton <br /> to date). We have already begun to deal with these damming them up so <br /> as to local{y confine the flow. Some of the seepage has actually stopped. <br /> Over the next seven months (March through September), we plan to take the following actions <br /> to correct the leachate seeps and prevent them from recurring next winter: <br /> 1. Regrading. Differential settlement areas will be regraded to prevent ponding next winter. <br /> T.1WF"MSOLIOWSTWIKE1AUSTINRDWOV-SEEP.WPO _j <br />
