The Sensitive Areas Ordinance (14-6K-1) was created to implement the environmental policies of the city’s comprehensive plan. It defines the reasonable use of properties which contain environmentally sensitive features. Sensitive features include wetlands, fully hydric soils, prairies remnants one acre or larger, stream corridors, archeological sites, steep slopes (18-24%), critical slopes (25-39%), protected slopes (40%+), and woodlands greater than or equal to 2 acres.
