program to reduce invasive species, especially buckthorn." The proposed <br />landscape plans are conceptual at this time. The College is beginning a process <br />to develop a Landscape Master Plan for the campus that will provide detailed <br />plans for the future of the campus landscape. The College has identified severa/ <br />issues for this plan, including proper care of the natural communities on the <br />campus, Best Management Practices for sformwater management, and <br />appropriate landscaping for shoreland zones. The issues raised in the comment <br />will be addressed as the Landscape Master Plan for the campus is developed <br />and as the detailed plans for the campus improvements are developed for <br />submission to the City. ,�� �w` <br />22. Comment: With the projected changes to the ecology,�the amount of stormwater <br />runoff will increase and its quality will decrease. ` �� <br />�:����. <br />`�v:�'' �, <br />Response: Comment acknowledged. Storm water treatment.measures <br />�m��� <br />associated with the pi�oposed capital improvements will be designed and <br />constructed in a manner that will not decrease the runoff qua�lity:discharging <br />from the College. ' `"=`�'� <br />�`F;a: n <br />23. Comment: Buffer zones are not required by either City. With nearly one mile of <br />shoreland, the College�has a significant impact on the water quality of both Lake <br />Johanna and Little Lake�sJo�an,�a. Both are on the MPCA's impaired waters list. <br />Response: The College ma <br />lakeshore areas as the La � <br />plans for the campus impro <br />zones of native vegetation for <br />'an is developed and as the detailed <br />:loped for submission to the City. <br />24. Comment: There is concern with�°erosion along the shoreline. The current <br />proposal includes more roadway a und the perimeter carrying potential for <br />even more erosion with more opp��� ity for pollutants to run directly into the <br />lakes. Mandatory buffer zones of n�tive and unmowed vegetation along its <br />� lakeshores might be considered as good mitigation measures for all properties <br />�„�• on these two impaired waters. <br />Response:��he City is beginning a process to develop a Landscape Master Plan <br />���r.. <br />for the camp�s that will provide detailed plans for the future of the campus <br />/andscape. T,he,� College has identified severa/ issues for this plan, including <br />proper care of the natural communities on the campus, Best Management <br />Practices for stormwater management, and appropriate landscaping for <br />shoreland zones. The College may consider buffer zones of native vegetafion <br />forila,k.eshore areas as the Landscape Master Plan is developed and as the <br />detailetl p/ans for the campus improvements are developed for submission to <br />the City. <br />25. Comment: Stormwater increases with every inch of impervious surface created. <br />TMDL studies of both lakes should perhaps be done to see what additional <br />capacity, if any, Lake Johanna and Little Lake Johanna have. <br />Response: The College is 94.64-acres in size and the entire combined drainage <br />area to both lakes from fhe RCWD HydroCAD model is 3, 893-acres. The <br />College comprises only 2.4 percent of the entire drainage area.
