vulnerable to damage from erosion and/or sedimentation, <br />are to be identified and receive special attention. <br /> <br />Limit Time of Exposure - all land-disturbing activity is to be <br />planned and conducted to limit exposure to the shortest <br />feasible time. <br /> <br />o <br /> <br />Limit Exposed Areas - all land-disturbing activity is to be <br />planned and conducted to minimize the size of the area to <br />be exposed at any one time. <br /> <br />eo <br /> <br />Control Surface Water - surface water runoff originating upgrade <br />of exposed areas should be controlled to reduce erosion and <br />sediment loss during the period of exposure. <br /> <br />f. <br /> <br />Control Sedimentation - all land-disturbing activity is to be <br />planned and conducted so as to prevent off-site sedimentation <br />damage. <br /> <br />Manage Storm Water Runoff - when the increase I the velocity of <br />storm water runoff resulting from a land-disturbing activity is <br />sufficient to cause accelerated erosion of the receiving watercourse, <br />plans are to include measures to control the velocity to the point of <br />discharge so as to minimize accelerated erosion of the site and <br />increased sedimentation of the stream. <br /> <br />Section 7 Mandatory Standards for Land-disturbing Activity <br /> <br />No land-disturbing activity subject to the control of this Ordinance shall be <br />undertaken except in accordance with the following mandatory standard: <br /> <br />a. Buffer zone <br /> <br />No land-disturbing activi ,ty during periods of construction <br />or improvement to land shall be permitted in proximity to a <br />lake or natural watercourse unless a buffer zone is provided <br />along the margi, n of the watercourse of sufficient width to <br />confine visible siltation within the twenty-five percent (25%) <br />of the buffer zone nearest the land-disturbing activity. This <br />subdivision shall not apply to a land-disturbing activity in <br />connection with the construction of facilities to be located <br />on, over, or under a lake or natural watercourse. <br /> <br />8 <br /> <br /> <br />
