4. Requirements:

1. Any land disturbing activities (i.e., vegetation has been removed, or the landscape has been graded or filled resulting in bare soil surfaces) shall include a stormwater management, erosion prevention and sediment control plan pursuant to the requirements of Sec 5.5.3 to be reviewed by the conservation board and approved by the city engineer.

In making determinations and decisions required herein, the city engineer shall consider the requirements of the most recent State of Vermont Stormwater Management Rules and Guidance document. The city engineer shall require the best practicable means be used to manage stormwater, prevent erosion, and control sedimentation. The city engineer is hereby authorized to develop performance standards to ensure conformance with these state stormwater management rules;.

For properties with frontage along Lake Champlain or the Winooski River, development that includes 400 square feet or more of new or redeveloped lot coverage shall establish a low-mow zone along the shoreline. A low-mow zone is a new or existing vegetated area that is not mowed more than once per year and allows vegetation to grow and mature. (Refer to Shoreland Best Management Practices established by Vermont Department of Environmental Conservation.). A low-mow zone shall be at least 15 ft. wide as measured inland from the 100 ft. elevation and shall be of a size equivalent to, or greater than, the new or redeveloped lot coverage, except that in no event shall a low-mow zone be required to extend more than 50 ft. wide as measured inland from the 100 ft. elevation or extend along more than 80% of a property's shoreline frontage.

For properties with frontage along Lake Champlain or the Winooski River, development shall be located no closer to the shoreline than existing development wherever reasonably possible.
