At the request of Chair Cihacek, Mr. Johnson provided a more detailed <br /> explanation of how staff identified an average citywide stormwater calculation for <br /> larger area projects based on what the city has experienced for those projects in <br /> recent years (e.g. Upper Villa, Sherran/Dellwood, Corpus Christi Church <br /> projects). Mr. Johnson noted that this impact fund would provide funding for <br /> those larger projects that would benefit the entire city as well as developments in <br /> the immediate area. <br /> At the request of Member Wozniak, Mr. Johnson clarified that residents would <br /> pay a one-time fee and would actually prove more beneficial and easier than <br /> maintenance of rain gardens or recertification costs of those installations. <br /> Continuing with his presentation, Mr. Johnson reviewed mitigation sequencing <br /> and stormwater districts in the city. Mr. Johnson noted that staff s suggestion was <br /> to apply that funding as near to development sites as possible to alleviate <br /> stormwater issues on the site and the immediate area, or at least within the <br /> immediate drainage area or that particular watershed district at a minimum to <br /> protect major water bodies and address ongoing flooding areas to lessen the <br /> overall impact. <br /> Specific to the upper limit for impervious coverage on residential lots, Mr. Culver <br /> explained that the city's Public Works and Engineering staff was currently <br /> working with the city's Community Development Department to modify current <br /> zoning ordinance language to address a standard or upper cap (currently 30%) for <br /> impervious coverage. Mr. Culver opined that from his personal perspective, he <br /> thought 50% impervious coverage limit was more reasonable; but advised that <br /> needed further research and vetting by the Planning Commission and City <br /> Council along with public input before any decision was made. <br /> Mr. Johnson's presentation continued with tracking of the proposed impact fund <br /> through creation of a special code and database for tracking, whether minor or <br /> major districts and their respective priorities and their location within the city <br /> and/or watershed district as regional benefits and localized flooding area <br /> addressed by priority. <br /> For next steps, Mr. Johnson sought further feedback from the PWETC for <br /> presentation to the City Council in July. <br /> Chair Cihacek asked how the Impact Fund was going to fund mitigation steps if <br /> those funds were not comparable to costs. <br /> Mr. Johnson advised that the fund took into consideration regional impact funds <br /> with profits intentionally built into smaller projects with tighter constraints, <br /> allowing leveraging for larger projects. <br /> Page 4 of 19 <br />
