Analysis
This ordinance makes various minor revisions to the city’s storm water management regulations to make them consistent with recent revisions to ch. 13 (Surface Water and Storm Water) of the Milwaukee Metropolitan Sewerage District’s “Rules”.
Body
Whereas, On October 25, 2010, the Milwaukee Metropolitan Sewerage District (“MMSD”) amended ch. 13 (Surface Water and Storm Water) of its “Rules”; and
Whereas, Communities within the MMSD service area are required to update their local storm water management regulations to be consistent with the revised MMSD “Rules” within 6 months of MMSD’s approval of those revisions; and
Whereas, The Department of Public Works-Infrastructure Services Division has identified the revisions set forth in this ordinance as being necessary to make the City of Milwaukee’s storm water management regulations consistent with the revised MMSD “Rules”; now, therefore
The Mayor and Common Council of the City of Milwaukee do ordain as follows:
Part 1. Section 120-3-5 of the code is amended to read:

18. PERSON means any individual, association, organization, partnership, firm, corporation or other entity engaging in the development or redevelopment of a property, [[either]] as the owner [[or as the owner’s agent]] >>of the property<< . Such corporate or individual ownership shall not be used to circumvent the intention of this chapter.

b. If the development or redevelopment occurring is subject to the requirements of sub. 2 and does not cause an increase of 0.5 acres or more of impervious area, the peak runoff flow rates under post-development conditions shall be at least 10% less than the peak runoff rates under pre-development conditions >>during 2-year and 100-year, 24-hour storm events<< .
