Page 10 #3. Warren Davis (cont). Alleged that there is a possibility of shallow water bisecting the Hammond property, that the Kleinfelder Report was inadequate -- the report makes no mention of springs near subject propertyf that if a trench were to bisect the property on the east boundary it would show as shallow strata. He asked why trench was not cut as required, that the state requires trenching --this would determine the location of shallow water. That he researched springs in this area; the spring flow is from northeast to southwest, that there is a water strata on the subject property,the Robidart property has a spring; there is a very old fig tree fed through the spring. A letter from Mr. Ley stated the spring had been there about 40 years. Those springs could be connected by an underground stream crossing the landfill site. Staff - It was the opinion of the State staff geologist that spr ngs in the area are the result of localized perched water layers and do not represent the underground water conditions of the area. The attached letter dated June 3,.1976, from the California Regional Water Quality Control Board Central Valley Region states that the test borings in the Kleinfelder Report satisfy the earlier request for a trench at the proposed landfill site #4. Olive Davis, 5261 Knox Drive, Linden (property at corner of Harney Lane & Clements Road Alleged that the Bite property has a high rainfall, severe rainstorms occur causing local flooding. The Swale draining the Hammond property has been 150' wide with flowing water. She said one time 3" of rainfall fell in a 2 -hour period, that there is frequent, heavy runoff and overflow into adjacent lands, and should recognize real, almost insurmountable drainage problems. Staff - As a high area relative to the adjacent terrain, the she will not experience flooding, and will not be inundated by the heavy runoff from storms. The staff drainage study has considered the runoff from a storm having a predicted frequency of once in 100 years. The design has determined 10 drainage areas as they exist today on the subject property. These areas have been retained in the design to continue to discharge the runoff proportionately to the same existing watercourses and will thereby not alter, decrease or increase the existing drainage problems of the adjacent properties. Moisture penetration will be monitored through the installatic of electronic tensiometer equipment at the landfill. „
