Attachment 4 Leaf Site FAQ's • How many leaves are collected at the site each year? 30,000-35,000 cubic yards Additionally, 500-1000 cubic yards of brush are illegally dumped. • How many leaves are generated from city crews during fall sweep? Approximately 3,000 cubic yards (weather dependent) are from city maintenance operations. This is less than 10% of the overall leaves collected at the site. • How much compost is generated from turning each year? 4,000 - 5,000 cubic yards • How much compost is left over after distributing to residents each year? About 1,000 yards (changes each year). This is available to sell but is not lucrative. Compost is sold at the end of the year to free up more space at the limited site. • What is the capacity of leaves we can currently handle? 30,000 cubic yards is the maximum we can take in and manage to turn into compost. • What are the sizes of the compost rows? When the rows are east to west, we have 17 rows. The compost rows are approximately 17 feet wide by 8 feet tall. Leaves are continually added to the compost rows throughout the year as the compost breaks down to manage the overage static pile. When turning is complete,10 rows are roughly 200- 250 yards of finished compost per and 7 rows progressively get smaller due to the layout of the site and maneuverability with the equipment. • What challenges are we seeing with replacing the existing compost turner? The front loader mounted turners, that is currently used as the site, are no longer available. Tow -behind models are PTO driven and require a larger size tractor. Tow -behind models require larger turning radiuses. Less leaves would need to be collected and compost could be made if we go with a tow -behind model. The price point of an over center self-contained unit is over $800,000 • Where will city maintenance staff bring fall sweeping leaves? Currently exploring options with vendors to static pile the sweepings and haul out during the winter months. Page 112 of 175
