A Poway landowner has filed a Clean Water Act lawsuit against the city for allegedly failing to adhere to water pollution control permits in the Lake Poway area along the trails leading to Mount Woodson and Potato Chip Rock. Poway City Attorney Allen Fenstermacher on Tuesday said the city denies all claims made in the suit and will file a response next month. He said the plaintiff, Kevin T. Kelly, filed the suit after the city rejected his request to purchase his property.
