The primary purpose of this section is to outline the regulations that a flag lot must adhere to:
A. Factors: When property is subdivided, flag lots shall only be allowed under the following circumstances:
1. When development of the property on a private lane utilizing existing zoning and subdivision regulations is not possible;
2. As a lot split or within subdivisions of fewer than ten (10) lots;
3. Where creation of a flag lot does not foreclose the possibility of future development of other large interior parcels that would be developable if a street were extended to them subject to the street connection requirements found within section 17-5-030(A); and
4. The flag lot does not have frontage on a classified street as defined by and illustrated in the Draper City Master Transportation Plan.
B. Development Standards: When flag lots are permitted, they shall be subject to the following conditions:
1. A flag lot as defined in section 9-3-040 shall be comprised of a narrow staff portion that is contiguous with a wide flag portion.
2. The staff portion of the lot shall front on and be contiguous to a local street, whether public or private.
3. Two (2) flag lots with contiguous staffs are prohibited.
4. The minimum width of the staff portion at any point shall be twenty feet (20') of paved access width. Greater staff width may be required by the fire marshal based on the access width requirements of the International Fire Code (IFC).
5. The maximum length of the staff shall be five hundred feet (500') as measured from the street right of way line to the beginning of the flag portion of the lot. The flag portion of the lot shall begin at the property line or line segments which define the minimum front yard depth per the minimum listed setbacks for main buildings.
6. The driveway access within the staff shall be paved with asphalt or concrete to a minimum width of twenty feet (20'). Design of the driveway shall provide a manner for controlling drainage water acceptable to the city engineer. The load bearing capacity of the driveway may be required to be designed to support the weight of fire and emergency vehicles as required by the fire marshal and city engineer.
7. The maximum grade of the staff shall not exceed ten percent (10%) except in the Hillside Sensitive Lands Overlay Zone where the maximum grade shall not exceed twelve percent (12%).
8. For lots where the staff portion is over one hundred fifty feet (150') in length, sufficient turnaround space for emergency vehicles shall be provided and an easement for access by emergency vehicles will be required. The fire marshal shall review and approve the design and location.
9. No building or structure shall be located within the staff portion of a flag lot.
10. The size of the flag portion of the lot shall conform to the minimum lot size requirement of the zone in which the lot is located, but in no case be less than fifteen thousand (15,000) square feet. The staff portion of the lot shall not be included in this minimum lot size calculation.
11. The front yard of a flag lot shall be on the side of the flag portion which connects to the staff and which is most closely parallel to the street the staff connects to. Setbacks for all main buildings shall be a minimum of twenty five feet (25') from all property lines for all flag lots less than or equal to twenty thousand square feet (20,000 ft²) in size, and thirty feet (30') for all flag lots greater than twenty thousand square feet (20,000 ft²) in size. Calculated lot sizes for this section do not include the staff portion of the lot.
12. All accessory buildings and structures shall follow the regulations contained in section 9-10-040 except that accessory buildings and structures over two hundred square feet (200 ft²) in size can be built no closer than fifteen feet (15') to a neighboring property line.
13. Fencing and landscaping shall comply with the limitations related to view obstructions listed in section 9-27-080. Fencing along or around the staff portion shall not exceed three feet (3') in height when abutting the front yard of an adjacent lot or parcel.
14. Fire hydrants shall be provided to serve the flag lot as required by the International Fire Code. Any fire hydrants located in the public rights of way shall be dedicated to the water provider for access to and maintenance of the hydrant.
15. The maximum height of main buildings on flag lots is limited to two (2) stories and a maximum of thirty feet (30').
16. Total lot coverage of flag lots is limited to no more than thirty five percent (35%) of the area contained within the flag portion of the lot.
17. Clear address signage must be installed and maintained at the street.
