PNCC Storm Catchment

This polygon layer defines the geographic boundaries of stormwater catchments within the city. Each polygon represents an area where rainwater and surface runoff are collected from streets, parks, and properties, then directed into the stormwater network to prevent flooding and manage water quality. These catchments assist the Council in managing stormwater flow, controlling flood risks, and planning drainage infrastructure. They also support maintenance activities, environmental monitoring, and future network upgrades to protect waterways and urban areas. Notes: The "Updated" date you see on this item indicates when the metadata was last revised. It doesn’t necessarily reflect when the data inside the feature layer was last refreshed. The data available for download on Palmy GeoHUB is updated daily, this results in a difference between what’s currently visible online and PNCC’s databases.

本多边形要素图层界定了城市范围内雨水汇水区（stormwater catchments）的地理边界。每个多边形对应一片汇水区域：该区域内的雨水与地表径流将从街道、公园及各类地块收集后，导入雨水管网，以此实现内涝防范与水质管控目标。此类汇水区可协助市政委员会开展雨水径流调度、洪涝风险防控及排水基础设施规划工作，同时为维护作业、环境监测以及未来管网升级提供支撑，以保护水生态系统与城市区域。
备注：本数据项标注的「更新日期」指元数据的最后修订时间，并非该要素图层内部数据的最后刷新时间。帕洛米地理枢纽（Palmy GeoHUB）平台的可下载数据每日更新，这会导致当前线上展示内容与PNCC数据库存在差异。
