Lot Coverage Ordinance <br />January 17, 2002 <br />Page 2 <br />• Structural coverage calculations shall include building protrusions more than 6' above <br />grade, i.e. not just the building footprint but the vertical projection of any parts of the <br />building that are more than 6' above grade. <br />• The outer 2’ of roof overhangs shall not be considered as lot coverage. <br />• Open decks with any portion of railing above 6’ will be counted as lot coverage in their <br />entirety. <br />• Hardcover limits for non-shoreland area needs to be looked at closer. The limit was not <br />decided - ideas included but not limited to: 50% hardcover limit, some other percentage <br />or a percentage of the buildable area on a property. <br />Anaivsi.s: <br />Of the approximately 3.000 residential lots in Orono, 616 lots are non-shoreland and less than 2 <br />acres in area. (Map-Exhibit E) A small sampling of these properties was looked at to develop <br />scenarios in which to determine the potential impacts of a hardcover limitation. Three scenarios <br />were developed- 50% hardcover on total lot area, 50% hardcover on buildable area and 80% <br />hardcover on buildable area. <br />Four different neighborhoods in the city were chosen where the lots are 2 acres or less in area - <br />Hackberr) Hill. Chevy Chase Drive, Webber Hills, and Chippewa l aneTumham Road. If a <br />survey was on tile for the property dated 1990 or later the property was included in the study. <br />Each area contains lots that are substandard in area as compared to the zo.ning requirement. * <br />Note: Many of the properties did not have surv eys on tile because hardcov er has not been an <br />issue with non-shoreland properties or improvements have not occurred on the property. For <br />example. 1 lackbcrry Hill neighborhood has 20 properties and only 7 had surveys. <br />Calculations of “total lot area" and “buildable area ” (total lot area minus setbacks) were then <br />completed for each property. The calculations are in table form (See E.xhibits A-D). Hardcover <br />calculations were then completed for each lot showing: <br />a. Allowed hardcover s.f at 50% of lot area. (Scenario 1) <br />b. Allowed hardcover s.f at 50% of buildable area. (Scenario 2) <br />c. Allowed hardcov er s.f at 80% of buildable area. (Scenario 3) <br />d. The amount of hardcov er existing on lot and percentage of total lot area <br />Included in the existing hardcover on lot calculation is the residence (including garage) detached <br />garage, deck. pool, driveway and walkways. In many cases, the size of the driveway and walk <br />were estimated because in the past hardcover was not an issue with these properties so when a <br />survey was completed hardcover items were not included.
