All "contaminated" runoff from the site <br />is routed into either the East or West ponds. Runoff is routed along the outside of the site via <br />channels. <br />The water quality features are generally in good condition. There is an accumulation of <br />tumbleweeds around many of the pipe inlets due to the shelter from the winds that these <br />locations provide (see Pic. 1). They should be removed from the pipe inlets to ensure that the <br />pipe capacity is not diminished. <br />The north runoff /drain filter located along the west side of the main drive has experienced <br />additional erosion along the north bank and needs to be repaired (see Pic. 2). <br />Please let me know if you have any additional questions or concerns in regards to the issues <br />that are discussed abo yr 'tfActWl conditions differ from what I have stated above. <br />Sincerely, <br />Ryan M.
