1.      A post-construction site with less than ten percent connected imperviousness, based on the area of land disturbance, provided the cumulative area of all impervious surfaces is less than one acre.

[e]        Land development activity of any size that, as determined by majority vote of the Village Board after consulting with the Village Engineer and the Department of Public Works, is likely to result in stormwater runoff which exceeds the safe capacity of existing Village owned drainage facilities or receiving surface waters, which causes undue channel erosion, unreasonably increases surface water pollution by scouring or the transportation of particulate matter, or endangers downstream property on a surface water.

(3)        EXCLUSIONS.  This ordinance is not applicable to activities conducted by a state agency, as defined under s. 227.01(1), Wis. Stats.
