Revised to include a note to restrict maximum building height along the Fore Street frontage; also depicts the revised B6 zone line as described in Item Height measurement package, total of 11 sheets New submittal that includes a description of how height is measured in Portland; includes an example of how Average Grade is measured; includes cross section graphics of the B6 Building Height Overlay at the 58 Fore Street site and abutting upland areas along Fore Street. We look forward to a site walk and workshop with the Planning Board on November 18 th.

5 Measuring Building Height from Average Grade In Portland, building height is measured as follows: Per City of Portland Code of Ordinances, Sec Definitions: Building, height of: The vertical measurement from grade, or the predevelopment grade on the islands, to the highest point of the roof beams in flat roofs; to the highest point of the roof beams or the highest point on the deck of mansard roofs; to a level midway between the level of the eaves and highest point of pitched roofs or hip roofs; or to a level two-thirds of the distance from the level of the eaves to the highest point of gambrel roofs. For this purpose the level of the eaves shall be taken to mean the highest level where the plane of the roof intersects the plane of the outside wall on a side containing the eaves. Establishing grade is done either by averaging the elevation of the proposed abutting ground surface at the building corners or by averaging the elevation of the abutting ground surface at the building walls at some interval around the perimeter of the building (i.e., every 2 feet). The interval must remain consistent (i.e., grade can't be determined from numerous points along the front side of a building and only a few on the back side; there must be equal spacing between points used to calculate grade). Multiple buildings that share walls or are connected, not counting enclosed catwalks or walkways, are considered a single building when calculating building height. Building structures that cross lot lines or condominium unit boundaries are counted as a single buildings for the purposes of calculating height. The "B6 Building Height Overlay & Building Envelopes" map submitted as part of the Zone Amendment application is directly based on the Height Map from the Eastern Waterfront Building Height Study. The maximum heights depicted on the Height Study Map were developed using the City's standard practice of measuring height from Average Grade. This submittal demonstrates how the maximum heights set forth in the height study and proposed height overlay map impact the 58 Fore Street site. We have included examples of building height envelopes measured from Average Grade and measured from flood plain (El = 10). These examples demonstrate that the maximum heights depicted on the height study were intended to be measured from average grade. As depicted in the examples, measuring heights from flood plain often results in buildings at or below the adjacent Fore Street grade. Because the height study includes view corridors where no buildings above Fore Street are permitted, it is clear that the height study anticipated that buildings would be built above Fore Street. 41 Hutchins Drive Portland, Maine 04102
