Wetlands, drainageways• <br />and floodplains will be protected from encroachment <br />and from alteration or destruction by filling, <br />grading, excavation or drainage.

These same factors act to <br />development which can be destructive if <br />regulated. Natural vegetation in shoreland <br />will be preserved insofar as practical and reason­ <br />able in order to retard surface runoff and soil <br />erosion, and to utilize excess nutrients. Clear- <br />cutting will be prohibited. In areas of soil or <br />wave action erosion, material stone rip rap <br />shoreline protection will be encouraged. <br />CMP 4-13
