Megow Subject: MCWD 17-283 Conditional Approval: 685 Old Crystal Bay Rd N, Orono Attachments: 17-283 Conditional Approval.pdf Good Evening Terrence, Please find the attached letter of conditional approval for the proposed maintenance garage improvements located within the Orono School Campus at the above referenced address. The final remaining administrative item is submission of a signed programmatic maintenance agreement. I sent you a draft agreement on 7/18/2017. As I am aware that construction would like to start as soon as possible, please give me an update on the expected timeline for the agreement to be signed. I am comfortable with issuing the permit and listing the agreement as a stipulation. With that in mind,would submission of an agreement by August 311t, 2017 be an appropriate amount of time for the school to execute the agreement? In the event that the school is no longer interested in a programmatic agreement, a permit specific agreement will be needed. Please let me know when you have a moment.
