7 COMPARISON OF RURAL CHARACTER STRATEGY OPTIONS ARENDT OPTION #2A In this option, an alternate strategy is presented as proposed by a member of the Rural Character Study Committee. The option includes: (1) increasing the minimum required lot size from 40,000 to 80,000 sq.ft. ; (2) providing no density bonuses; and (3) limiting the number of lots to the number which can be achieved under a conventional plan. Although open space acreages and percentages are shown for this option, they reflect owner preferences and have no relation to density bonuses. This option is based on Randall Arendt's approach, combined with increased minimum lot size. The analysis is based on a tract size of 50 acres, but the template is set up sp that any tract size can be evaluated. Average lot size calculations include the area in the the lot as well as the street right-of-way. A range of "constraint" conditions is presented to illustrate the impact of the option. "Constraints" can include poor soils, wetlands, steep slopes, etc. TRACT SIZE = 50 ACRES _ Arendt Option #1A Severe < Moderate > Slight Constraints RCSC Option Lot Yield Units Avg Units Avg Units Avg Units Avg % Open Per Lot Per Lot Per Lot Per Lot Open Space Gross Lot Size Gross Size Gross Size Gross Size Space Acres Acre Yield [Acres] Acre Lots [Acres] Acre Lots [Acres] Acre Lots [Acres CONVENTIONAL DEVELOPMENT 0% 0.0 0.50 25 2.00 0.25 13 4.00 0.375 19 2.67 0.50 25 2.00 CLUSTER DEVELOPMENT == 20% 10.0 0.80 40 1.00 0.25 13 3.20 0.375 19 2.13 0.50 25 1.60 30% 15.0 0.90 45 0.78 0.25 13 2.80 0.375 19 1.87 0.50 25 1.40 40% 20.0 1.00 50 0.60 0.25 13 2.40 0.375 19 1.60 0.50 25 1.20 50% 25.0 1.10 55 0.45 0.25 13 2.00 0.375 19 1.33 0.50 25 1.00 60% 30.0 1.20 60 0.33 0.25 13 1.60 0.375 19 1.07 0.50 25 0.80 70% 35.0 1.30 65 0.23 0.25 13 1.20 0.375 19 0.80 0.50 25 0.60 ______ OBSERVATIONS: 1. These options produce very different results due to the lack of density bonuses under the Arendt option. An equally important factor is the "starting point" or how many lots a property owner can obtain under a conventional development plan. 2. The Arendt option, including the two-acre lot size requirement, is more restrictive than the current RB-Rural Buffer zoning. For example, an owner limited to 13 lots under a conventional plan could "cluster" under the existing ordinance and attempt to achieve the maximum number of units allowable - 25. The Arendt option above would no more than 13 lots and is thus less flexible than the current RB standards. 3. The Arendt option would permit individual wells and septic tanks to be used in all options except the "moderate constraints - 70% open space" and "slight constraints - 60% and 70% open space" categories.
