In 1999 the City of Portland (City) began to require that stormwater management facilities (SMF) be built when private property is newly developed or redeveloped (City Code Chapter 17.38). Proper maintenance and upkeep of SMFs is essential to ensuring they function appropriately. The City’s Maintenance Inspection Program (MIP) is tasked with inspecting stormwater management facilities on private properties in order to ensure that they are being properly operated and maintained and to meet provisions of the City’s NPDES Municipal Separated Storm Sewer System (MS4) permit. Greenroofs are one type of SMF that are installed to satisfy this requirement. Understanding the long-term maintenance needs of a greenroof is essential to reaching MIP goals established by City Code and the MS4 permit. Data collection occurred between November 2011 and May 2013 at private properties in Portland, Oregon during routine maintenance inspections of stormwater management facilities for the City’s Maintenance Inspection Program (MIP).

In order to cope with urban flooding, water scarcity and rainfall-runoff pollution comprehensively, a conceptual tank model of urban storm water system is proposed. Tank model is a multi-layer, multi-objective model, so design of urban storm water system is more complex than that of urban storm sewer system. Some principles of design of urban storm water system are discussed, such as Low Impact Development, Smart storm water management, and so on.
