IMP Drainage

The Infrastructure Management Program (IMP) is a five-year rolling program which focuses on the maintenance of San Antonio’s Infrastructure. Service needs are identified city wide and are scheduled for street maintenance, alley maintenance, drainage maintenance, sidewalks, traffic signals, pavement markings and Advanced Transportation District (ATD) related projects. Drainage Maintenance Program Drainage maintenance addresses debris removal within our Natural Creeks and restores the shape of constructed channels to ensure proper water flow. Criteria for projects to be placed on the list for drainage maintenance are dependent upon: imminent danger to private property and safety to citizens, impact to infrastructure, debris volume, number of citizen service requests, and density of development. This maintenance cycle may have minor adjustments when conditions of a specific facility may warrant being moved up on our maintenance schedule.基础设施管理计划（Infrastructure Management Program，IMP）是一项为期五年的滚动式计划，专注于圣安东尼奥市的基础设施维护。全市范围内摸排服务需求，并统筹安排街道养护、巷道养护、排水设施养护、人行道、交通信号设施、路面标线以及先进交通区（Advanced Transportation District，ATD）相关项目的实施。 排水设施养护计划：排水养护工作主要针对天然河道内的杂物清理，并修复人工开挖渠道的形态，以保障水体正常流通。纳入排水养护项目清单的判定标准包括：对私有财产及市民安全构成的即时威胁、对基础设施的影响程度、杂物堆积体量、市民服务请求数量以及区域开发密度。当特定设施的状况需要提前纳入养护计划时，本次养护周期可做出小幅调整。
