This dataset has the following 14 columns:

Column NameAPI Column NameData TypeDescriptionSample Values
Yearyearcalendar_dateThe time period that the data was recorded and measured
Number of Trees Plantednumber_of_trees_plantednumberThe total number of trees available for sale each year. Any tree unsold is then planted by the City of Naperville's Department of Public Works. It is assumed all trees are planted.
Cost Benefit At Time of Plantingcost_benefit_at_time_of_plantingnumberQuantified average of the overall benefit based on stormwater, electricity, air quality, property value, natural gas and carbon dioxide (CO2) at the time of planting.
Cumulative Annual Cost Benefit At Time of Plantingcumlative_annual_cost_benefit_at_time_of_plantingnumberCost benefit of trees at the time of planting multiplied by the number of trees planted.
Stormwater Runoff Intercepted (Gallons)stormwater_runoff_intercepted_gallonsnumberTrees control stormwater runoff at the source by intercepting and holding rain, increasing filtration through the tree's root system, and reducing soil erosion by slowing rainfall before it strikes the soil. This field is an average of the stormwater runoff of trees planted in a single year.
Cumulative Annual Stormwater Runoff Intercepted (Gallons)cumlative_annual_stormwater_runoff_intercepted_gallonsnumberStormwater benefit of trees from the Arbor Day Tree Sale planted since 2010, accounting for annual tree growth and the corresponding benefit increase. A 6 inch caliper tree size is estimated at maturity.
Cooling Savings (Kilowatts)cooling_savings_kilowattsnumberAverage energy benefit in kilowatts at the time of planting. It is estimated based on the ability of trees to increase home energy efficiency by providing shade and transpiration to cool the air during warm months. During the winter, trees can reduce wind speeds by acting as a natural buffer.
Cooling Savings In Energy Costscooling_savings_in_energy_costsnumberConversion of the kilowatt savings from planted trees to a real dollar cost based on Naperville utility rates.
Cumulative Annual Cooling Savings (Kilowatts)cumlative_annual_cooling_savings_kilowattsnumberCooling savings of trees in kilowatts from the Arbor Day Tree Sale planted since 2010, accounting for annual tree growth and the corresponding benefit increase. A 6 inch caliper tree size is estimated at maturity.
Cumulative Annual Cooling Savings In Energy Costscumulative_annual_cooling_savings_in_energy_costsnumberConversion of the kilowatt savings from planted trees to a real dollar cost based on Naperville utility rates.
Carbon Dioxide Reduction (Pounds)carbon_dioxide_reduction_poundsnumberEstimate of carbon dioxide (CO2) benefit of trees associated with containment of CO2 in roots, trunks, steams and leaves and added the benefit trees located near buildings have to reduce heat and air conditioning demands, thereby reducing emissions associated with power production.
Cumulative Annual Carbon Dioxide Reduction (Pounds)cumlative_annual_carbon_dioxide_reduction_poundsnumberEstimated carbon dioxide (CO2) benefit of trees in pounds from the Arbor Day Tree Sale planted since 2010, accounting for annual tree growth and the corresponding benefit increase. A 6 inch caliper tree size is estimated at maturity.
Cost Benefit At Maturitycost_benefit_at_maturitynumberAs trees mature, the benefits they provide increase. This field captures the estimated cost benefit of the trees planted in a single year once those same trees are mature. Benefits vary by specie type. A common mix of specie types available at the Arbor Day Tree Sale with a 6 inch caliper maturity has been averaged to provide this estimate.
Cumulative Annual Cost Benefit At Maturitycumlative_annual_cost_benefit_at_maturitynumberCumulative annual benefit of Annual Arbor Day Trees planted since 2010. Benefits vary by specie type. A common mix of specie types with a 6 inch caliper maturity has been averaged to provide this estimate.
