This revision is necessary because of an excessive amount of storm water runoff (2.4 cfs in a 10-year storm) that would flow over the curb behind lot 196. This amount of flow may create a hazardous situation for vehicles and pedestrians during a major storm event. Therefore, structure #52913 is added to eliminate this potential problem. The water line in Prestwick Lane is also revised to account for the storm sewer crossing. If you have any questions or need additional information, please call me. Thanks.
