TOWN OF AMHERST BICENTENNIAL COMPREHENSIVE PLAN<br />

less costly infrastructure improvements that do not<br />

compromise public safety or welfare.<br />

• The more compact development patterns allowed by<br />

conservation development lessen the amount <strong>of</strong> streets<br />

<strong>and</strong> utilities required, reducing initial site improvement<br />

(developer) costs <strong>and</strong> long-term (taxpayer) costs for<br />

maintenance <strong>and</strong> services.<br />

• Conservation development improves the visual quality<br />

<strong>of</strong> new development as seen from public roads by<br />

facilitating the maintenance <strong>of</strong> “green” buffers.<br />

• Conservation development preserves open space for the<br />

community at little expense to the taxpayer while<br />

creating enhanced value for developers. With proper<br />

planning <strong>and</strong> design, the open space can form part <strong>of</strong> an<br />

interconnected, community-wide system <strong>of</strong> parks,<br />

greenways, <strong>and</strong> trails.<br />

Conservation development differs from the cluster residential<br />

option provided by Section 203-3-7 <strong>of</strong> the <strong>Town</strong>’s Zoning<br />

Ordinance in its emphasis on design st<strong>and</strong>ards, flexibility, <strong>and</strong><br />

incentives to accommodate development while achieving<br />

meaningful open space preservation in a variety <strong>of</strong> contexts.<br />

Current cluster residential provisions should be modified to<br />

provide the <strong>Town</strong> with the option to m<strong>and</strong>ate the<br />

conservation development approach. The revised regulations<br />

should address the following:<br />

• Density: The starting point for determining allowable<br />

density should be the maximum number <strong>of</strong> lots that<br />

could realistically be developed on the l<strong>and</strong> per the<br />

requirements <strong>of</strong> the underlying zoning district, taking into<br />

consideration environmental limitations as demonstrated<br />

through a “yield plan.” The minimum lot size <strong>and</strong><br />

dimensional requirements specified by conventional<br />

zoning would be reduced to allow appropriate areas to be<br />

dedicated as permanent open space.<br />

• Incentives: Incentives in the form <strong>of</strong> density bonuses<br />

should be established to encourage use <strong>of</strong> this<br />

development option. The bonuses should be established<br />

on a sliding scale, increasing as the percentage <strong>of</strong><br />

dedicated open space increases.<br />

• St<strong>and</strong>ards: St<strong>and</strong>ards should be established for the design,<br />

use, ownership, <strong>and</strong> maintenance <strong>of</strong> dedicated open space<br />

areas. Most commonly, a private homeowner’s<br />

association assumes ownership <strong>and</strong> maintenance<br />

responsibilities. Other options include a private l<strong>and</strong><br />

conservation trust or, in cases where the open space<br />

would provide a key linkage in the town-wide open space<br />

system, it could be dedicated to the <strong>Town</strong> <strong>of</strong> <strong>Amherst</strong>.<br />
