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.

• to be sited

• Pasco County • Created June 2, 1887 • Seat: Dade City • Largest City: New Port Richey • Total Area: 867.95 sq miles • Population : 464,697 • Part of the Tampa/St. Petersburg metro area
