The infiltration basin treats the rear <br />drainage from the three lots while the remaining drainage flows to Lois Lane to the south. <br />Comments: <br />1.Call out the proposed high point on the east side of Lot 1 <br />•Adjust proposed contours to maintain minimum 2% slope where <br />possible <br />2.There is an existing low area at the southeast front corner of Lot 1 <br />•Consider coordinating with the adjacent existing property owner to fill in <br />the low area and prevent it from backing up to the east. <br />•Adjust grading along the eastern side lot line of Lot 1 to allow for <br />drainage to reach the street. <br />Attachment 2: City Engineer Memo Dated January 4, 2024
