SUBSTITUTE Amending numerous sections of Chapter 37, the Public Stormwater System Including Erosion Control.
DRAFTER'S ANALYSIS: This ordinance makes numerous changes to Chapter 37 to update the code requirements.

Section 37.09(3)(a) is also being amended to update and change the sediment control design performance standards, including setting specific standards for redevelopment or resurfacing within the Rock River TMDL area. Moreover, the design stan...
