The Shoreland Overlay extends 1000 feet from the shoreline and provides in part: SeC. 78-1285. Vegetation alterations. (b) Intensive vegetation clearing within 75 feet of the shoreline, on steep slopes or within the bluff impact zone within the Shoreland Overlay District is prohibited. Limited clearing of shrubs and trees less than six inches in diameter and cutting, pruning and trimming of trees of any size is allowed to provide a view to the water from the principal dwelling site and to accommodate the placement of permitted stairways and landings, picnic areas, access paths, beach and watercraft access areas, and permitted lockboxes, provided that the screening of structures, vehicles or other facilities as viewed from the water, assuming summer, leaf-on conditions, is not substantially reduced. (Ord. No. 101 2nd series, § 1(10.56(16)(I)), 2-24-1992; Ord. No. 127 2nd senes, § 7, 7-11-1994) Steep slope means lands having average slopes of 12 percent or greater as measured over horizontal distances of 50 feet or more, that are not bluffs. Intensive vegetation clearing means the complete removal of trees or shrubs in a contiguous patch, strip, row or block. In the area of 3165 NSD that exceeds a 12% slope, Morrie has a number of damaged and sickly trees. Some of the trees are in the fill area. Others are just in the wrong place or have been trimmed to protect overhead powerlines for so long that they've got a bizzare shape. Could you or Melanie meet me and out there to see what amount of clearing would be tolerated? Let me know.

First established the toe of bluff per definition; then established the top of bluff per definition; then calculated slope (rise over run) for a)the entire distance from toe to top; and b) the distance from toe to 955' (which is approximately the point 25' above the OHWL). In no case did the calculated slope get to more than 25%. We do not consider short segments of>30% slope as defining a bluff—it has to be based on the average of toe to top and/or toe to the 955 contour. Unless the topo you are working from is significantly different from that in our GIS system, it appears you do not have a bluff to deal with. i
