311 Service Requests - Graffiti Removal - 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 graffiti removal requests made to 311 and all requests completed since January 1, 2011. The Department of Streets & Sanitation's Graffiti Blasters crews offer a vandalism removal service to private property owners. Graffiti Blasters employ "blast" trucks that use baking soda under high water pressure to erase painted graffiti from brick, stone and other mineral surfaces. They also use paint trucks to cover graffiti on the remaining surfaces. Organizations and residents may report graffiti and request its removal.
311 sometimes receives duplicate requests for graffiti removal. Requests that have been labeled as Duplicates are in the same geographic area and have been entered into 311’s Customer Service Requests (CSR) system at around the same time as a previous request. Duplicate reports/requests are labeled as such in the Status field, as either "Open - Dup" or "Completed - Dup." Data is updated daily.

如描述于https://data.cityofchicago.org/stories/s/311-Dataset-Changes-12-11-2018/d7nq-5g7t，本数据集的功能已被https://data.cityofchicago.org/d/v6vf-nfxy所取代。该数据集仅包含历史数据。

自2011年1月1日起，所有提交至311的开放式涂鸦清除请求以及所有已完成的请求均包含在内。街道与环境卫生部门负责为私人财产所有者提供破坏性涂鸦清除服务。涂鸦清除队伍使用配备高压水枪的“喷射”卡车，以苏打粉为介质清除砖石及其他矿物表面的涂鸦。此外，他们还使用喷漆卡车覆盖剩余表面的涂鸦。组织和个人可以报告涂鸦并请求其清除。

311有时会收到重复的涂鸦清除请求。被标记为重复的请求位于同一地理区域，并且与先前的请求在大约同一时间被输入至311的客户服务请求（CSR）系统中。重复报告/请求在状态字段中被标记为“开放 - 重复”或“完成 - 重复”。数据每日更新。
