311 Service Requests - Tree Debris - Historical

As described in https://data.cityofchicago.org/stories/s/311-Dataset-Changes-12-11-2018/d7nq-5g7t, the function of this dataset was replaced by https://data.cityofchicago.org/d/v6vf-nfxy. This dataset is historical-only.

All open tree debris removal requests made to 311 and all requests completed since January 1, 2011. Large piles of branches or bushes may be picked up by the Department of Streets and Sanitation.
311 sometimes creates duplicate requests for tree debris removal. When there is an open tree debris request, a duplicate request is created when the exact same address and the exact same service request type are used. Streets and Sanitation responds to the initial request opened and closes the duplicates. A forestry "Clam" is the name of the vehicle the Forestry Bureau deploys to collect tree debris.
Data Owner: Streets and Sanitation (http://www.cityofchicago.org/content/city/en/depts/streets.html).

自2011年1月1日起，所有向311提出的开放树木残骸清理请求以及所有已完成的请求。街道与环境卫生部门负责收集大量树枝或灌木。
311有时会为树木残骸清理创建重复请求。当存在开放树木残骸请求时，若使用相同的地址和完全一致的服务请求类型，则会创建重复请求。林业部门派遣的名为“Clam”的车辆用于收集树木残骸。
