CONCLUSION
AIM AND OBJECTIVES
• Aim • The aim of this project is to develop a suitable
model, analysis and parcel(s) for the location of a waste disposal site.
• Objectives • Determine the areas that are restricted and not
restricted • Determine the areas that range from least suitable to
highly suitable • Determine which parcel(s) of land is equal to or
greater than 5acres in size.
DATA/CRITERIA
• Criteria: • Airport safety, • Floodplains, • Wetlands, f • ault areas, • unstable areas
• Suitable layers • Pasco county 2006 land use land cover • Road – Euclidean distance • FEMA flood zones • Slope
• Restriction layers • Roads – 50 meters buffer • Lakes – 500 meter buffer • Parks – 500 meter buffer • Rivers – 150 meter buffer • Sinkholes • Unincorporated cities • Critical linkages
METHOD
• Suitable layers • Used the weighted overlay to combine all of them • 30% for fema flood zones and slope respectively • 20% for land use land cover and distance
• Restriction layers • Converted everything into raster • Set the roads, rivers, lakes and sinkholes to null • Unioned the parks, cities and critical linkages
respectively to the pasco administrative boundary before convering to raster
• Did a raster calculation and multiplied everything • Final output
• Did a raster calculation and multiplied the suitable layer and the restriction layers together
• Eliminated the less suitable areas using the “set null” function
• Converted the result to polygon • Selected parcels that were more than or equal to 5
acres in size
• Municipal solid waste landfills have, over the years, become a source of public concern. People have become more aware of the potential threat to the environment and health of the people and animals alike.
• With and increase in population over the past decade, the availability of space for siting a landfill has become a huge problem for the society at large.
• In 1990, the United States generated over 195 million tons of municipal solid waste. By now this would have more than tripled.
• This project looks at a suitable site to place a waste disposal. Site suitability analysis assists in identifying specific criteria or restriction (Kumar and Shaikh 2012).
• The acquisition of a suitable site for waste disposal is becoming increasingly complex and hard due to population expansion and growth.
• Environmental hazards and prevention and pollution is at the frontline when considering the site and location to dump waste.
• The selection of suitable sites for waste disposal has to be based upon a set of criteria depending on legislative and local laws of the area.

Final Output
RESULT
• From the final out come it can be observed that only a very small portion of land(s) can be determined suitable to site a landfill
• Only 34 land parcels met the criteria set for siting a suitable waste disposal site
• The smallest size was 5.31 acres while the largest piece of land was 16.26 acres
• Not all physical criteria such as zoning type, environmental protected areas was added to this analysis.
• Some criteria will have to be ignored if at all anymore waste disposal needs to be sited
• More analysis is needed to come to a precise conclusion as to where a waste disposal needs to be sited
• Some other criteria that needs to be considered includes, population density, protected areas, zone types, and elevation
• From this short analysis it can be observed that modeling the environment if one of the quickest ways of conducting field anaysis before heading out.
