, . AET#22-00173- Page 2 of 10 PROJECT INFORIVIATION Oak Hill, Inc. is proposing to redevelop an existing residential lot ]ocated at 2264 Shadywood Road in Orono, Minnesota. Currently, the site is occupied by a one-story, single family residence originally constructed in 1931. As part of the proposed redevelopment, the existing foundation will be incorporated in the proposed two-story, single family home. Oak Hill, Inc. proposes to remove the top 3 courses of the masonry block foundation wall, corefill the remainder of the wall solid, and construct the new foundation wall above. The proposed home will not have a basement level. An excavation and survey program performed by Oak Hill, Inc. indicated the foundation consists of 24" wide spread footings and that approximately '/z inch of differential settlement has occurred in the existing foundation. The foundation will also be expanded to include an attached garage with second-story living space located south of the existing home. The area of the planned addition is currently covered by grassy areas that abut the existing home. To improve the drainage around the new home, grade will be raised approximately 1' near the foundation and sloped away from the house. The proposed driveway will be located to the east of the new home, with access to Crystal Bay Road. As part of the proposed redevelopment, the City of Orono is requiring a geotechnical exploration program be performed at the site to evaluate the existing conditions and the proposed construction. The City is also requiring the existing basement to be filled prior to new construction. The presented project information represents our understanding of the proposed construction. This information is an integral part of our engineering review. It is important that you contact us if there are changes from those described so that we can evaluate whether modifications to our recommendations are appropriate.
