The plans are <br /> dated 2-3-10. We have the following comments with regards to engineering matters: <br /> • Most of the garage and a portion of the driveway are being placed over an area with <br /> existing hard cover. The slight increase in hard cover will generate a negligible increase <br /> in stormwater runoff to the north. <br /> • It appears that a required stormwater pond was never constructed with the 2006 or <br /> 2007 building addition and parking lot expansion project. We recommend that the • <br /> construction of the approved pond be required regardless of the garage project <br /> proceeding. <br /> • This project will disturb more than 100 CY of material. Sediment and erosion control <br /> information meeting the requirements of Orono's City Code 79-7(c)(2) must be <br /> submitted. The minimum $2000 sediment and erosion control financial security should <br /> be required of the owner for this permit. <br /> If you have any questions, please call me at(651) 604-4894 or send an email to <br /> darren.amundsenCa�bonestroo.com. <br /> Yours very truly, <br /> � i . <br /> Darren Amundsen <br /> Cc: Tom Kellogg <br />
