Box 66 � Crystal Bay, MN 55323 G� 952 249-4600 ( ) ��o�'� Fax: (952) 249-4616 CONSTRUCTION NEAR A WETLAND Wetlands perform important environmental, aesthetic and hydrologic functions. In 2005 the City adopted regulations to ensure that wetlands continue to perform these functions and to improve their functioning (City Code Sections 78-1601 through 1614). These regulations require the creation and protection of buffers around wetlands when certain construction or land alteration activities occur. These activities are: Construction of a new house or a major remodeling that involves removal of more than 50 percent of the structure and the portion removed is more than 50 percent of the ma'rket value of the stru�ture. OR Construction or land alterations when all of these conditions exist; a. The portion of the property disturbed by construction or land alteration activity drains #o the wetland b. The amount of grading exceeds 50 cubic yards or involves the disturbance of more than 5,000 square feet. c. There is a net increase in impervious surfaces that drain to the wetland, new impervious surface is added closer to the wetland than existing impervious surfaces, or there is a change in drainage patterns that the City Engineer determines will increase the velocity or rate of runoff to the wetland. The width of the buffer varies from 50 feet to 16.5 feet. A 20 foot setback from the buffer is required for buildings and subsurface structures such as swimming pools. If the wetland is on adjacent property but part of the buffer is on the property where construction activity is occurring, then the buffer must be provided. Even if the wetland buffer is not required, the buffer and buffer setbacks must be observed. Attachments: A. Steps for Obtaining a Permit B. Request for Wetland Buffer Evaluation C.
