<br />BONESTROO'S APPROACH TO THE <br />WOODBURY PROJECT EMPHASIZES A <br />COST-EFFECTIVE AND MEASURED <br />APPROACH BY MEETING THE PERMIT <br />REQUIREMENTS WITHOUT EXPENDING <br />ADDmONAL RESOURCES ON MEASURES <br />THAT EXCEED THE PERMIT STANDARDS. <br /> <br />methodology that will result in an acceptable Loading Assessment <br />submittal. At present, we have the MPCA's preliminary agreement on our <br />approach. The results of these discussions with the MPCA will be used by <br />several cities in preparing their nondegradation submittals. <br /> <br />Bonestroo's approach to the Woodbury project emphasizes a cost-effective <br />and measured approach by meeting the Permit requirements without <br />expending additional resources on measures that exceed the Permit <br />standards. <br /> <br />We prepared Woodbury's Loading Assessment using a routed water <br />quality model based on William Walker's PondNET. We augmented this <br />modeling with in-lake modeling at select lakes in Woodbury's system. <br />Woodbury chose this approach because they had already developed, <br />through other projects, the information necessary to populate the <br />PondNET model. Furthermore, the City wanted a comprehensive water <br />quality model for future use. <br /> <br /> <br /> <br />ROCHESTER, MN KINGS RUN NONDEGRADATION PILOT ANALYSIS <br /> <br />The purpose of the Kings Run Nondegradation Pilot Analysis project was <br />to provide the City of Rochester with preliminary feedback demonstrating <br />the technical process and issues involved in a Loading Assessment and <br />nondegradation analysis. <br /> <br />Through this project, our staff first realized the benefits of PondNET over <br />other models for routed water quality modeling. Specifically, PondNET was <br />shown to be more effective at modeling agricultural watersheds. This <br />functionality was critical since many of the Cities involved in the <br />Nondegradation Reporting were agricultural in the baseline condition. <br /> <br />Through this pilot project we also came to understand the utility of routed <br />models and that they were only warranted in cases where ponds or other <br />BMP's occurred in series or were extensive in developed landscape. <br /> <br />The Kings Run Nondegradation Pilot <br />Analysis helped the City of <br />Rochester with issues involved in a <br />Loading Assessment and <br />nondegradation analysis. <br /> <br />OTHER BONESTROO LOADING ASSESSMENTS USING PONDNET ROUTED MODELING <br /> <br />Bonestroo is currently working on the following Loading Assessment and <br />Nondegradation Reporting projects: Chaska, Rochester, Eagan, Apple <br />Valley, and Farmington. In each of these projects we utilize the routed <br />PondNET water quality model. In Eagan, Apple Valley, and Farmington, <br />the modeling infrastructure and input data already existed. Chaska and <br />Rochester decided to invest in the routed water quality model in order to <br />have a city-wide water quality model for future use. <br /> <br />BONESTROO'S APPROACH TO THE ELK RIVER LOADING <br />ASSESSMENT <br /> <br />Throughout our work on other loading assessments we have met <br />frequently with MPCA staff. Initially, the MPCA had little guidance to offer <br />in how these loading assessments should be prepared. Even now, after <br />many discussions with city staff and their consultants, the MPCA is <br />noncommittal as to the technical specifications for creating a valid loading <br /> <br />-#- Bonestroo <br /> <br />3 <br />
