RA — Rural Agricultural District
A lot in Rural Agricultural needs at least 40 acres of gross area and 600 feet of width, and only one dwelling unit is permitted per 40 acre lot (Section 26.02; Section 9.02.A.1). When a farm is consolidated, an existing farm dwelling may be split off on a parcel of at least 2 acres (Section 9.02.A.1).
A new house needs at least 1,800 square feet of floor area with a basement or 2,000 square feet without one (Section 26.02). Minimum lot depth is 120 feet, and depth may not exceed four times the width (Section 26.02, footnote b). A nonconforming lot of record may still be built on with a conforming use and structure if it can be reasonably developed, does not significantly harm surroundings, and meets all setback requirements (Section 3.05.A). Contiguous undersized lots under the same ownership are treated as one parcel, though the Planning Commission can waive the merger for platted lots with public utilities (Section 3.05.C).
