Communities can make very important decisions on how they want to grow. Part of this decision involves analyzing the advantages and disadvantages of possible land uses. A Cost of Community Services Study (COCS) is an inexpensive way to evaluate the economic contributions of open space, farmland, and residential and commercial development. These studies help communities evaluate the costs of different combinations of land uses, and balance goals such as maintaining affordable housing, creating jobs, and conserving land and resources.
It has become conventional in COCS studies to divide land use into three categories: residential, commercial/industrial, and farmland/open space. One of the most common procedures for analyzing fiscal impact is to calculate a COCS ratio for each land use category The ratio compares how many dollars worth of local government services are demanded for each dollar collected. A ratio greater than 1.0 suggests that for every dollar of revenue collected from a given category of land, more than one dollar is spent.
A Cost of Community Services has not been preformed yet for Charlestown, but studies have been performed for other towns in Rhode Island. The ratios below show that even in Little Compton, residential development costs more than it pays.

Of course in Charlestown, some forms of residential development do pay more than they cost in services. Waterfront properties pay large tax bills and are often used as summer homes and do not send students to school or require other services. In Charlestown 67 percent of the tax bill is paid by coastal properties. But most of Charlestown\’s future growth potential is not in the waterfront areas, meaning that future growth is likely to become increasingly expensive.
According to the COCS studies, the largest single expenditure category for communities is the public school system. Since open space and commercial development in themselves do not place any burden on the schools, it should not be surprising that their ratios are lower than those for the residential category.
