Rural Residential — THE THREE ACRES IS AN AVERAGE, NOT A FLOOR. Table note 2 lets lot sizes be averaged across a subdivision, so lots may vary provided the average is three acres in RU, and note 3 conditions that on Department of Health standards for conventional septic systems and private wells being met. A MAJOR subdivision must additionally meet the flexible lot subdivision requirements of § 232-17. The maximum ratio of lot WIDTH TO LOT DEPTH is 1:3 (table note 1) — a shape rule with no field. The coverage figure includes IMPERVIOUS SURFACES, not just buildings.

Hamlet — THE BASE ROW IS THE NO-SEWER CASE. Table 1 prints the Hamlet district twice: without public or community sewer it needs 30,000 sq ft, 75 ft of width, a 30 ft side yard and a 75 ft rear yard at 25% coverage; with sewer available it falls to half an acre, 50 ft of width, 15 ft and 40 ft at 50% coverage. The front yard is a RANGE, 20 ft minimum and 50 ft MAXIMUM. The maximum ratio of lot WIDTH TO LOT DEPTH is 1:3 (table note 1) — a shape rule with no field. The coverage figure includes IMPERVIOUS SURFACES, not just buildings.

Hamlet Business — The base row is BASIC CONSERVATION at one acre. ENHANCED CONSERVATION IS A DENSITY BONUS, NOT A SECOND ROW YOU CAN CHOOSE. Table note 4 and § 232-18 grant the smaller lot only where the applicant provides ALTERNATIVE SEPTIC SYSTEMS and best site design practices under § 232-8B. What qualifies is the design of the development, which has no term in the condition vocabulary, so the bonused figure is stated here rather than recorded. In H-B the enhanced figure is 0.5 acre. The front yard is a RANGE, 20 ft minimum and 50 ft MAXIMUM. The maximum ratio of lot WIDTH TO LOT DEPTH is 1:3 (table note 1) — a shape rule with no field.

What qualifies is the design of the development, which has no term in the condition vocabulary, so the bonused figure is stated here rather than recorded. In CL the enhanced figure is 2 acres, and it requires best site design standards without an alternative septic system. The maximum ratio of lot WIDTH TO LOT DEPTH is 1:3 (table note 1) — a shape rule with no field. The coverage figure includes IMPERVIOUS SURFACES, not just buildings.

Table note 4 and § 232-18 grant the smaller lot only where the applicant provides ALTERNATIVE SEPTIC SYSTEMS and best site design practices under § 232-8B. What qualifies is the design of the development, which has no term in the condition vocabulary, so the bonused figure is stated here rather than recorded.

The maximum ratio of lot WIDTH TO LOT DEPTH is 1:3 (table note 1) — a shape rule with no field. The coverage figure includes IMPERVIOUS SURFACES, not just buildings.
