Christine Mattson From: Christine Mattson Sent: Tuesday, April 28, 2015 3:21 PM (t, To: 'Will Haack' Q �' Cc: 'jaxelson@comcast.net; 'ron@ronbrennerachiteets.com'; 'Kelly-Schoborg Land Services, Inc.'; Melanie Curtis; Lyle Oman; John van Dyck Subject: RE: 2330 Oliver Hill/#2015-00388 Attachments: Building Height 2014.pdf; SKM_C654e15042814160.pdf Will, We received an updated survey dated 4-22-2015, but it is not to scale. As requested the survey now shows the approved grading plan elevations for the Oliver Hill subdivision as the existing topography, thank you. During my review of the number of stories calculation, it appears that the lower level of the home (not including the unexcavated garage area) is classified as a"story"and not a"basement"as is needed; you have a 3-story home where 21/2 stories above a basement is the maximum permitted. The first floor elevation is shown as 1004.7'which results in the 998.7'being the determining elevation 6 feet less (see below definitions). According to the code section below, at least 50% of the perimeter of the basement must be 6'below existing grade . Attached is a highlighted copy of the survey showing an approximate location of the unexcavated area (in green); the existing 998'elevation (in yellow); the perimeter of the basement(in pink) and the area of the basement that is conforming (in blue). Attached is our information sheet on building height and number of stories. I believe if you lower the house and/or first floor elevation (FFE) at least 3 feet the lowest level would meet our definition of a basement and not be considered a story. Please modify the proposed house elevations on the survey and/or house plans and resubmit two copies for our review. Have the surveyor reference the elevation used for the number of stories calculation on the survey.

The perimeter of the basement does not include portions of the house or garage that do not have a lower level but are merely "unexcavated".Artificially raising the grade adjacent to the foundation of a structure(by filling or by a combination of filling and retaining walls)above the surrounding natural terrain shall not be allowed as a method for converting a defined story to a defined basement,regardless of any other benefits to the property of such action. Finished grade that increases more than one foot from existing ground level shall be considered as artificially raising the grade.However, artificially raising the grade when such action merely restores a previously excavated site to its original natural grade may used as a method for converting a defined story to a defined basement. 1
