Carroll, Madison,
and Washington counties.
Description:
The Four-County Northwest Arkansas Regional Solid Waste Management
District requested CAST to conduct a GIS study to see if there were suitable areas within Northwest Arkansas to locate a regional
landfill.
|
|
The area includes Benton, Carroll, Madison, and Washington counties. |
The District provided the criteria for landfill siting. CAST provided
the data, and analysis based on the District's information to create large
format maps to be used in the decision making process.
Additionally, the Center provided all the resulting data from the analysis to a private contractor hired by the District to carry out further detailed studies of this regional issue.
Criteria provided by the Four-County Northwest Arkansas Regional
Solid Waste Management District:
2. No landfills within 300 feet of incorporated areas
3. No landfills within 2 miles of designated streams
4. No landfills within 10,000 feet of airports
5. No landfills within 12 miles of existing landfills
Maps 1 through 5 showed in red all the areas which did not satisfy the
individual criteria for locating a landfill. Using a GIS, it is now possible to
analyze several of these criteria simultaneously.
This maps shows in red all the areas which are not suitable based on
criteria 1 through 4
If "proximity to existing landfills" is taken into account as well, one can
see that most of the four-county area is unsuitable for a new
landfill.
