Recycling Pilot Program Summary Table 1 Pilot Study Components Selection of Pilot Areas The City selected pilot areas of 330 -360 single - family homes — the approximate size of one full collection route. The pilot route selections were made after a review of U.S. Census data and discussions with Waste Management staff. Each area was roughly similar in demographics except that a second single- stream area, called the Contrast area, was selected that featured newer homes and more affluent residents. A control route of comparable size was also selected that had no changes in collection method. The area chosen for the Control route had a slightly higher average income level than all the other test areas, except for the single- stream contrast area. Time Period For each pilot area, residents' behavior was monitored in a two -month "Before" period (June — July 2004) followed by a four -month "During" period (August — November 2004). Data from certain weeks were excluded from the data analysis to avoid bias. These included: ■ the week of July 4 during the "Before" period; ■ the first two weeks of the "During" period, because information had just been sent out to residents of the non - Control pilot areas, and previous studies have shown there is an initial surge of participation that results from direct contact; and 6 DRAFT B1605 Monday Monday Tuesday Wednesday Thursday Friday Single- Single- Increased Increased Larger Bin Control Stream Stream Frequency Education Capacity (Current Contrast System) Frequency of Every other Every other Weekly Every other Every other Every other Collection week week week week week Bins /Carts 64- gallon 64- gallon 18- gallon bin 18- gallon bin Two 22- 18- gallon bin cart cart gallon bins with wheels Added Only Only Only Extra Only None Education pertaining to pertaining to pertaining to educational pertaining to new sorting new sorting new materials new bin system system frequency of capacity collection Demographics Similar Newer Similar Similar Similar Slightly homes & higher more average affluent than income than other pilot other pilot areas areas except Contrast Selection of Pilot Areas The City selected pilot areas of 330 -360 single - family homes — the approximate size of one full collection route.
