Sensitive Lands is the name given to streams, wetlands, and tree groves that provide wildlife habitat and water quality benefits. The City of Lake Oswego protects these natural resources by regulating development in and near Sensitive Lands. The location of protected streams, wetlands, and tree groves is shown on the Sensitive Lands map.
