I We are reviewing building permit application for a new home at 2350 Oliver Hill. I'm working on the number of stories calculation and trying to determine if the lowest level meets the City's basement definition. The first floor elevation is shown as 1008.8' which results in 1002.8' being the determining elevation 6 feet or less (see below definitions). To help with this calculation, please show the 1002.8' contour on the survey through the house. In order for the lowest level to qualify as a basement at least 50% of the perimeter must be at the 1002.8' elevation or lower. If the lowest level can't meet the basement definition, the house will be a 3-story home where 2 1/2 stories are allowed by code. As I've calculated it currently it doesn't appear to meet the 50%. Hopefully your additional information will help to clarify the basement. Please don't hesitate to contact me if you have any questions.

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. Building height means the vertical distance between the highest adjoining ground level at the building or ten feet above the lowest ground level, whichever is lower, and the top of the cornice of a flat roof, or the deck line of a mansard roof, or the uppermost point on a round or other arch-type roof, or the median height of the highest gable of a pitched or hipped roof. Topographic changes which elevate the adjoining ground level above the existing terrain shall not be considered in determining building height. For a pitched or hipped roof situation, regardless whether the highest living space in a building is a half-story or full story, if the highest living space contains windows (excluding skylights)the upper measuring point for defining building height shall be the median height of the top of the highest window and the highest peak of the roof. 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 walls 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. 2
