The students discovered a number of surprising issues, including the fact that Hanover has never called for a study looking at the economic benefit of open space. Careful studies in eleven New Hampshire towns have shown that the tax revenues raised by new residential developments are often insufficient to pay for the increased demand for community services. Open space properties demand just 21 cents to 94 cents for every dollar of taxes paid. Other tools for conserving open space beyond the exclusive use of the Zoning Ordinances should be considered. These two mechanisms will help retain remaining open space while still providing housing to residents.
Misconceptions exist about the cost of preserving open space.
Studying other economic impact analysis tools used in other towns across the state. Hanover should begin to charge impact fees to developers for the added costs of services of new developments such as schools, parks, recreation areas, water, sewer, police and fire departments. Hanover should also consider an excise tax to generate revenue for purchasing land to designate as open space. Density Bonuses provide incentives through zoning exemptions for developers to voluntarily cluster development to one-fourth of their property. Clear and equitable guidelines should be created regarding the use of Density Bonuses.
