You would need to treat an area of existing <br /> asphalt equivalent to the area required to reduce the impervious surface ratio to less than 15%. The pervious <br /> paver system would need to be designed and follow current DNR technical stands. This design would be <br /> submitted in lieu of a full blown mitigation permit. You will still use the mitigation permit application (see <br /> attached) however, the TSS and vegetative buffer requirements would not be part of your application. The paver <br /> system and future maintenance would need to be deed recorded in a maintenance agreement. <br /> Another option would be to treat the roof water from the addition with a small rain garden or bioretention <br /> basin designed to achieve 90%infiltration (average annual). The same application requirements would apply as <br /> described above. Let me know if you have any questions. <br /> Thanks, <br /> Jason Tuggle <br /> Urban Erosion Control Analyst <br /> Dane County Land & Water Resources <br /> Water Resource Engineering Division <br /> (o) (608) 224-3735 (m) (608) 516-2275 <br /> http://lwrd.countvofdane.com/wred/ <br /> https://mail.countyofdane.com/owa/ 1/12/2016 <br />
