Interim Storm Water Ordinance <br />August 6. 1993 <br />Page 3 <br />quality." There are generally two reasons to implement BMP’s from a water quality standpoint. <br />The first is to protect the existing level of water quality from future degradation. The second <br />is to correct existing water quality problems. The two facets of implementing BMP’s include <br />site planning and storm water management. <br />From an administrative standpoint, adoption of BMP’s and NURP standards is pointless <br />without formalizing a procedure for reviewing projects. That procedure should include an <br />application process, a review process, and penalties for failure to adhere to the provisions. As <br />a result, the ordinance placed in front of you for consideration is not simply a one sentence <br />document stating "we hereby adopt NURP standards and BMP’s", but rather is a complete <br />interim approach to dealing with nonpoint source pollution. <br />Future Storm Water Management Plan <br />Please realize that we have termed this an Interim Storm Water Ordinance because it does <br />not incorporate a comprehensive Storm Water Management Pian for the City, which has yet to <br />be developed. Such a plan will be a fairly exhaustive study of the individual watersheds and <br />subwatershed.s within the City and will define par'meters and criteria for their protection. Such <br />a plan is mandated by the Metropolitan Surface Water Managenent Act, Chapter 509 of <br />Minnesota Laws. 1982. Also known as "509" regulations, these will become a front burner item <br />as soon as the Minnehaha Creek Watershed District 509 Plan is approved. Our storm water <br />management regulations ultimately will have to be in compliance with the Watershed District <br />Plan, as well as other regulations discussed in Exhibit G. We have been preparing to develop <br />such a plan by taking the initial step of acquiring 1" = 100 ’, 2’ contour interval topographic <br />maps for the entire City at a cost approaching $80,000. The nonh half of the City has been <br />mapped, and the souUi half is nearing completion.
