5.2 Allowed Activities 



The following uses shall be allowed within a wetland or wetland 

 buffer to the extent that they are not prohibited by any other 

 chapter or law and provided they are conducted using best 

 management practices, except where such activities result in the

 crops, or alteration of the wetland by changing existing 

 topography, water conditions or water sources; 



d. Existing and ongoing agricultural activities including 

 farming, horticulture, aquaculture, irrigation, ranching or 

 grazing, of animals. Activities on areas lying fallow as part 

 of a conventional rotational cycle are part of an ongoing 

 operation. Activities which bring an area into agricultural 

 use are not part of an ongoing operation. An operation ceases 

 to be ongoing when the area on which it was conducted has 

 been converted to another use or has lain idle so long that 

 modifications to the hydrological regime are necessary to 

 resume operations. 



e. The maintenance (but not construction) of drainage ditches; 



f. Education, scientific research, and use of nature trails;
