Christine Mattson From: Christine Mattson Sent: Monday, April 25, 2016 2:43 PM To: 'Jennifer Storms' Cc: Mike Fritz; curtkallio@kallioengineering.com; 'susan.schroder@yahoo.com'; Roger Peitso; Melanie Curtis Subject: 4220 Chippewa Lane/#2016-00289 Attachments: Landscape Walls & Retaining Walls 2014.pdf Jen, Per our conversation at the counter this afternoon, I've reviewed the updated survey submitted showing the additional elevations requested. Piease see below: 1. Building Height. With the additional elevations provided it appears the lower level of the home (not including the unexcavated garage area) may be classified as a "story" and not a "basement"which is needed. Based on the contour information provided the home appears to be a 3-story home where 2 % stores above a basement is the maximum permitted. Based on the analysis,the proposed first floor elevation (FFE) is 977.1'which results in the 971.1' being the determining elevation 6 feet less (see below definitions). Please have the survey updated to show where the 971.1 crosses the foundation of the proposed home. Please note at least 50%of the perimeter of the foundation must be at or below the 971.1'. 2. Landscape Plan. A landscape plan was submitted. Any proposed patios,grading, sidewalks, retaining walls shown on the landscape plan should be reflected on the survey. Attached is a copy of our landscape and retaining wall information sheet. 3. Certificate of Survey. An updated survey dated 4-25-2016 was received reflecting the house being moved to the East to meet the side yard setback (and you brought in a landscape plan). Because this survey is not complete (#1 and #2 above) the survey will not be reviewed until the number of stories calculation is resolved and the landscape plan is shown on the survey(i.e. patio, retaining walls, showing top and bottom of wall elevations, sidewalks, etc.). Basement means that portion of a building that is partly or completely below the existing ground/evel. A basement shall be considered as a story for purposes of determining the number of stories in a building, when the finished surface of the floor above the basement is more than six feet above the existing ground level for more than 50 percent of the basement's perimeter. 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. Half story means the uppermost floor of a building in which (i) the intersection of the exterior wall and the roof is not more than three feet above the floor elevation, and(ii) not more than 60 percent of the floor area within the exterior wal/s of the uppermost floor exceeds five feet in height as measured from the floor to the rafters. Floors exceeding these parameters shall be deemed a full story. Please don't hesitate to contact me if you have any questions.
