A. 
A lot in the RR, RA, or CV Districts may derive its Frontage and access by means of a narrow portion of land connecting the Public Highway and the larger rear portion of the lot, provided that no portion of the access from the frontage shall be less than 25 feet wide. The front yard setback of such a flag lot shall be measured from the rear lot line of the lot between the flag lot and the public highway. In the case of a lot with radial or angled side lot lines, the front yard setback shall be established where the lot meets the minimum lot width requirement when measured parallel to the street from which the lot derives access.
B. 
Two or more adjacent flag lots shall provide access by a common driveway as provided in Chapter 240, Subdivision of Land.
C. 
No more than four flag lots shall be served by a common driveway.
The following structures are exempt from building height requirements in the table above: church steeples, water towers, farm structures, public monuments, and those structures subject to approval under other local laws such as Chapter 202, Renewable Energy Facilities, and Chapter 249, Telecommunications Towers and Facilities.
For major subdivisions in the RR and RA Districts, the minimum lot size shall be two acres, unless the subdivider elects to proceed with subdivision approval pursuant to the conservation subdivision procedures as provided in Chapter 240, Subdivision of Land, in which case, for the purposes only of determining the number of lots which could be permitted if the property were subdivided into lots conforming to the minimum lot size requirements, the minimum lot size shall be deemed to be one acre.

This determination by the Town Planning Director of the maximum number of dwellings shall be recorded in the Tompkins County Clerk's Office and cross-referenced to the deed of the lot in question and the maximum number of dwellings for said lot shall not increase even if said lot is thereafter subdivided.
