8. Sensitivity Analysis – Cost of Water -Lines Intersect at $.005 -Water Price Likely to Increase

9. Sensitivity Analysis - Maintenance -Artificial Turf Has A Set Maintenance Cost -Intersect At $45000 -Reasonable Scenario

10. Sensitivity Analysis - Income -Real Grass Capped Around 50K -Likely Scenario -Intersect At: Income - $85000 EUAC $90646 -District Regulations Vary

11. Conclusion Artificial Turf Has An Advantage IF: – Field time can be sold – Field is heavily used – Price of water increases Real Grass Is Still a Viable Option Based upon our Equivalent Uniform Annual Cost Analysis, Artificial Turf has an Economic Advantage over Real Grass in Given Conditions.
