To date, there has been a significant level of confusion and consternation on the part of all parties involved relative to Orono code requirements. The issues relate directly to: 1) the lack of an overall as-built grading survey for the subdivision; 2) the fact that on at least one lot the 'existing grade' information provided for that individual lot does not match the grading plan that was approved during the subdivision platting process; 3) confusion as to how to interpret City codes regarding the measurement of building height and determinations of whether a lowest level is a story and whether an upper floor is a half-story; and 4) the fact that the height and basement vs. story determinations are required by City code to be based on pre-existing grade (for construction on raw unimproved land) or the new existing grade (when new grades are approved via an approved grading plan for a new subdivision). To clarify for all: Pre-existing grade is the site topography prior to any road construction or site grading to establish drainageways and building pads. New existing grade is the new topography that was approved to be established as part of the subdivision review and approval process, as indicated on the approved grading plan. Current existing grade is the actual topography created on the site by the developer's grading contractor, as it exists today. Issues Encountered to Date - Lot 5, Block 1: Based on the most recent submitted survey work, the current existing grades for Lot 5, Block 1 do not match the approved grading plan, and in fact have extended the created building pad approximately 10-15 feet further eastward than the approved grading plan. The proposed house for Lot 5 is significantly larger than the conceptual footprint on the approved grading plan (2800 s.f. vs. 1800 s.f.); is located much closer to the cul-de-sac than the conceptual house; has a lowest floor half a foot higher than the concept plan; and has a basement ceiling height half a foot higher than the concept plan. Taking into account all these factors, the proposed house's lower level would just meet the requirements for being a basement based on the 'current existing grade', but it does not quite meet those requirements based on the 'new existing grade' (likely need to slide the house 3' to the west to meet the requirement for lowest level being a basement). An issue here is that the driveway apron in front of the garages is proposed at a slope of 8%-13% and increases to 40% in the northerly 2
