Excess <br />water from this depression flowed southeasterly to <br />three landlocked off-site ponds having bottom ele- <br />vations below 930 feet. <br /> <br />I <br /> <br />I <br /> <br />I <br />I <br />I <br /> <br />I <br />I <br /> <br />As indicated on the aerial photo of June 25, 1940 <br />(Figure 3), the site and the area to the east and <br />south contained four ponds. The westernmost pond, <br />which formerly flowed into Silver Lake (and the <br />only one on the site), was probably about 18 inches <br />deep; during dry periods it dried up as shown ln <br />the October 30, 1953 aerial photo (Figure 4). The <br />u.s. Geological Survey (U.S.G.S.) maps of 1952 and <br />1967 and a 1957 aerial photo, Figures 5, 6 and 7 <br />respectively, indicate that the western pond was <br />intermittently open water or a dry mud depression <br />depending on climatic conditions. <br /> <br />!I <br />!I <br />I <br />il <br />il <br />I <br />[I <br />I <br /> <br />I <br /> <br />These Figures also indicate that the present east- <br />erly ponds did not exist, because they could drain <br />completely to the east until Windsor Court was <br />built, with up to 12 feet of fill across a land- <br />locked pond below elevation 930. When Windsor <br />Court was built, a storm drain to accept the flow <br />was constructed into the southeast corner of the <br />Windsor Center site. This storm sewer would have <br />intercepted and propogated the southeasterly flow <br />of storm water. However, surrounding its inlet <br />elevation of 937.5, a berm has been landscaped to <br />elevation 940t feet. The ponds having surface <br />elevations exceeding 938 feet would not exist, <br />except during storms, if the 15 inch drain in the <br />southeastern portion of the site were functional. <br />However, because of the berming around the storm <br /> <br />I <br /> <br />I <br /> <br />111-3 <br /> <br />I <br />
