Land Disturbance

A Land Disturbance Permit (LDP) is required for any land disturbance of one acre or more per Ottawa’s Municipal Code Chapter 14 Article III. Land disturbance includes any activity that changes the physical conditions of landform, vegetation, and hydrology, creates bare soil, or otherwise may cause erosion or sedimentation. Activities include, but are not limited to: clearing, grading, excavating, removal of vegetation, stripping, grubbing, filling, logging, and storing of materials. Any new development or redevelopment that cumulatively disturbs one acre or more, must also obtain a LDP. Please contact the Stormwater Coordinator at 785-229-3632 or with your plans before initiating work. The City has provided a guidance document Land Disturbance Permit Worksheet to aid in determining whether a LDP is required.
