Floodplain Restriction

No construction, without the written prior approval of the city shall be allowed within a floodplain, and then only after detailed engineering plans and studies show that no flooding and no obstruction to the natural flow of water will result. If construction is permitted, all finished floor elevations shall, at a minimum, meet or exceed the minimum flood protection elevation of table 14-5.

The existing creeks, lakes, reservoirs or drainage channels, not within a public easement, traversing along or across portions of this subdivision, shall remain as an open channel at all times and shall be maintained by the individual owners of the lots that are the individual owners of the lots that are traversed by or adjacent to the drainage courses along or across such lots. The city shall not be responsible for the maintenance and operation of such private drainageways or for the control of erosion. Each property owner shall keep the natural drainage channels traversing or adjacent to the property clean and free of debris, silt or any substance which would result in unsanitary conditions. The city shall have the right of ingress and egress for the purpose of inspection and supervision of maintenance work by the property owner and to alleviate any undesirable conditions that may occur. The natural drainage channels are subject to stormwater overflow and natural bank erosion to an extent that cannot be definitely defined, the city shall not be liable for damages of any nature resulting from the occurrence of these natural phenomena, nor resulting from a failure of any structures within the natural drainage channels. The natural drainage channel crossing each lot is shown by the floodplain easement line as shown on the plat.
