The plans are dated <br /> 12-29-11. We have the following comments with regards to engineering matters: <br /> • The addition appears to drain to a wetland, disturb more that 50 cubic yards of soil, and increase the <br /> hard cover draining to the wetland. This triggers Orono's wetland buffer ordinance. <br /> • The impacted wetland is a Manage 3 (east)wetland and requires a 16.5 foot wide buffer. <br /> • ]ohn Smyth reviewed the site and found the Manage 3 wetland buffer area to be free of invasive <br /> species. The applicant should add the buffer location for the Manage 3 wetland on the Certificate of <br /> Survey. No other work is required to meet the wetland code. <br /> • This project will disturb more than 100 CY of material. Sediment and erosion control information <br /> meeting the requirements of Orono's City Code 79-7(c)(2) must be submitted. The minimum $2000 <br /> sediment and erosion control financial securiry should be required of the owner for this permit. <br /> If you have any questions, please contact me at(651) 604-4894 or darren.amundsen a(�.stantec.com. <br /> Sincerely, <br /> Stantec <br /> �-- _ <br /> y � <br /> _:_____. _.____ <br /> Darren Amundsen <br /> Cc: Chris Mattson <br />
