Over the last year the CRWD Board of Managers spent a considerable amount of time in committees as well as board meetings making changes to the rules for the CRWD that were adopted in 2011. There is a link below to the amended rules that were approved on April 15, 2015. 

Changes in the rules include minor verbage changes to make the rules clearer and easier to understand.  There has also been some changes to the drainage rule that allows for tree removal and minor repairs without a permit.  Please make sure you read the rules or just give our office a call if you have a quick question.  It is better to be safe by asking than do a project without a permit. 

Contact Bev Nordby or James Fett if you have any questions, 507-434-2603.
