Preliminary Plat Application 13-3591 <br /> Bayside Meadows <br /> Page 4 <br /> 5.3 The proposed vertical curve at station 7+50 does not meet required standards. Per the State Aid <br /> Manual for Sag Vertical Curves,a minimum K value equal to 36 is required for the 30 mph design, <br /> and a K value equal to 35.79 is proposed. The profile should be revised to meet minimum <br /> standards. <br /> 5.4 The vertical profile is extremely steep at the location of the proposed 100' radius horizontal curve <br /> (approximate station 4+00). The combination of steep slope and tight curve could create safety . <br /> concerns during snowy or icy conditions. The applicant should consider modifying the road layout <br /> to lessen the slope and increase the radius. <br /> 6.0 PRELIM]NARY PLANTING PLAN: <br /> 6.1 Tree calculations should be shown on the Planting Plan. One shade tree is required for every 40' <br /> of road frontage. <br /> 6.2 Tree preservation and removal should be included with the Planting Plan so the extent of tree <br /> clearing can be�eld verified. . <br /> Please let me lrnow if you have any questions or need additional information. <br /> Sincerely, <br /> BOLTON&MENK, INC. <br /> s8td�'L� `��c� <br /> v <br /> Robert E.
