Rural Agricultural — Front yard and road frontage are measured from the CENTER LINE of the road, not the property line (Note 6).

The Planning Board may adjust the front yard to the average of the closest four parcels. Coverage is maximum IMPERVIOUS SURFACE, not building footprint, and applies both to each lot and to an entire subdivision including new roads and public areas (Note 8, § 121-74). Height is measured above average grade. A nonresidential structure may not exceed 6,000 sq ft of footprint, excluding agricultural and residential accessory structures and structures for educational, religious or charitable uses and camps (Note 10). Lots in limited development and conservation subdivisions, and rear lots, may have shorter frontages (Note 5).
