<br />not cover all of the areas we are required to under the NPDES pennit. Staffhas also <br />revised this section and it is also attached in your packet. It is much more detailed as to <br />what the requirements are. The proposed Storm Water Ordinance is new. The language <br />contained in this ordinance is similar to a majority of other communities such as <br />Woodbury, Valley Branch Watershed District, Brown's Creek Watershed District, and <br />Ramsey-Washington Metro Watershed District. <br /> <br />One of the key components of this ordinance is to comply with the State's goal of <br />obtaining a pollutant loading water quality model that will provide, at minimum, changes <br />in Average Annual Flow Volume, Total Suspended Solids and Phosphorus. This <br />modeling will be based on two time periods: from 1988 (1988-1990) to the present <br />(2000-2005), and from the present to 2020 or ultimate development, whichever occurs <br />first. The following are the levels to be obtained with development: <br /> <br />. Reducing the amount of phosphorus by 60010 for new developments and 40% for <br />redevelopment that do not currently meet 60%. <br />. Volume control measures to determine infiltration rates prior to approval of plans <br />. 60010 removal of Total Suspended Solids <br />. Both ordinances refer to the City's Engineering Design Guidelines for other <br />design criteria <br /> <br />Staff held a public meeting for builders, developers, excavators, and small utility <br />contractors on Wednesday, February 28, 2007 as well as several staff meetings to review <br />the proposed ordinance. The attendees were asked to provide comments and the city did <br />not receive any. <br /> <br />Staff is requesting the Council review the attached ordinances. Staff will be at the May <br />7t11 meeting to request approval of the ordinances. <br />
