It is my understanding that a different company that we get permits from all of <br /> the time will be applying for this portion of the project. <br /> • I spoke with my supervisor about the "MCWD approved slash wall" (I assume they meant to write <br /> MCWD SPLASH wall). <br /> o He claimed that after the 2014 floods the MCWD approved these walls, but no one here knows <br /> anything about it, so no, it is not something we suggest or have approved. <br /> o We are okay with them having a retaining wall on top of the rip rap as long as the retaining wall <br /> portion is out of the 100-yr floodplain i.e. above the 931.5' contour. <br /> o Right now the site plan I have been provided with shows the bottom of the retaining wall to be <br /> under the 931.5' elevation, which is basically not allowed and not needed. <br /> • FYI, we allow Riprap to extend to top of bank or 2 Ft. above the 100-year floodplain elevation, <br /> whichever is lower. <br /> o This might sound counterintuitive, but on steep slopes, sometimes 2 Ft. above the 100-yr <br /> contour is lower than the top of bank because the bank has eroded so much and the top of it is <br /> really high up. <br /> I hope all of this helps and doesn't cause more confusion, but if you have any questions don't hesitate to give me a call if <br /> you need some more explanation.Thanks! <br /> k s• Chase Vanderbilt <br /> District Representative <br /> Minnehaha Creek Watershed District <br /> Direct 952.641.4580 <br /> ,„ + 15320 Minnetonka Blvd.,Minnetonka,MN 55345 <br /> « www.minnehahacreek.orq <br /> CC <br /> sais•yry;•Anv{r <br /> From: Laura Oakden [mailto:loakden@ci.orono.mn.us] <br /> Sent:Tuesday,August 15, 2017 2:41 PM <br /> To:Chase Vanderbilt<cvanderbilt@minnehahacreek.org> <br /> Subject: FW:3155 Casco Cir Orono- Permit <br /> 1 <br />
