The plans are dated 8-26-10. We have the following comments with regards to engineering matters: • There is some minor grading in the 0-75' setback in order to manage the stormwater runoff on the subject property. • The plan is acceptable from an engineering standpoint. • It appears that this project will disturb more than 100 CY of material. Sediment and erosion control information meeting the requirements of Orono's City Code 79-7(c)(2) must be submitted. The minimum $2000 sediment and erosion control financial security should be required of the owner for this permit. If you have any questions, please contact me at (651) 604-4894 or darren.amundsen@stantec.com.
