• Recommendations of the June 27, 2001 Environmental Board 8075 20th Ave North The Environmental Board reviewed a plan for a variance to build a garage at 8075 20th to give feed back on environmental considerations of this site. At he time of review, the Environmental Board recommended that the applicant check with Rice Creek Watershed District to ensure that no wetlands are impacted; and if the building size would exceed the allowable fill (no building size was available at the time of the meeting) than they work with the watershed to develop a plan. The Environmental Board would like this plan to include a simple method of maintaining additional impervious runoff on the site since it is in a designated lake protection area adjacent to Hardwood Creek. Since the meeting a site visit has indicated that the proposed area of the garage construction is devoid of wetlands, and that any water running from this site seems to be directed to a natural depression between the creek and the building site, with a good distance of reed canary grass between the depressional area and the creek. Target Ryan • The Environmental Board voted to forward the following recommendation: • The draft EAW states on page 19, second -to- last - paragraph, that it is not known what "impact will result from the increased volume of runoff into the wetlands in the regional park reserve and George Watch Lake" The last paragraph on that page also states that phosphorous runoff loads will increase from the current 22 lbs per year to 60 lbs per year after the development is completed, all of it going to "the wetlands in the regional park reserve and George Watch Lake" An analysis should be done to fully determine these impacts to the Rice Creek Chain of Lakes Preserve, wetlands and lakes. If the Rice Creek Watershed is unable to provide this, it may be appropriate for the applicant to provide this analysis. The analysis should utilize computer modeling. Draft Comprehensive Plan That an emergency building moratorium ordinance be enacted for all residential development and consideration for all development. (see letter and memo) Environmental Board Goals Should be forwarded to the Planning and Zoning Board for their information. (attached)
