Christine Mattson From: Brett Eidem [BEidem@minnehahacreek.org] Sent: Thursday, December 20, 2012 3:48 PM To: Christine Mattson Cc: psoberg@ptspro.com; Brandon Wisner Subject: Closeout of 680 Minnetonka Highlands Lane Attachments: 2012-11-02 680 Mtka Hghids La_3.jpg; 2012-11-02_680 Mtka Hghlds La_1.jpg; 2012-11-02_ 680 Mtka Hghlds La_2.jpg Christine, I recently had a conversation with Paul Soberg, the owner of 680 Minnetonka Highlands Lane. We discussed the final closeout of his site, and said that you need to get confirmation from us that the site stabilized to release some sort of assurance.According to our rules to confirm a site is completely stabilized, there needs to be a uniform perennial vegetative cover with a density of 70%over the entire pervious surface area, or other equivalent means necessary to prevent soil failure under erosive conditions. In this case, the site was inspected in early November, and the front yard definitely met this 70%stabilized.There is a portion of the back yard that has not met that requirement, and there is still going to be small scale construction to be done there (finishing of a deck). I am confident to say there is not evidence to believe that any of this exposed sediment will leave site, or reach any storm drains. It is relatively flat, and would need to travel a long distance over a well stabilized area to get close to the edges of the site.We are going back to confirm that the backyard will be stabilized after final deck construction in the spring, but have been assured that no large machinery or earth moving is necessary with this. I give our permission that the site is stabilized to the point where no soil will leave the site.
