Drawing upon the debates on 'suburbanisms' and 'arrival space', this article explores the complexities for welfare governance in multiethnic peripheries. The paper bridges two themes of the contemporary 'suburban century': the intensified global migration flows and the peripheral condition of suburbs worldwide; the work refers to the Municipality of Pioltello, a multiethnic suburban area in Milan's region. This double-sided perspective reveals governance dynamics, here discussed through the concept of 'welfare offloading'. In the observed neighborhood, governmental complexities disclose profound interdependencies with the region's urban core and across municipalities; welfare tensions are 'offloaded' from the central core to peripheral regions.

This paper aims to analyze the flood hazard in the city of Monza, which periodically suffers from overflows from both the river Lambro and the urban drainage system during wet weather conditions. A unified Urban Flash Flood Model of Monza is therefore developed to capture both sources of hazard. The model is first validated by comparing the results of simulations with historical data related to the area of Monza, then is exploited to obtain maximum flood depth and velocity maps for three different return periods. Overall, the results show the different nature of the flood-related hazard and the sewer-related hazard: the former is concentrated across the rivers whereas the latter spreads patchy over the territory. Furthermore, the former features much larger water levels and flow velocities, which result in more serious hazard to citizens. [ABSTRACT FROM AUTHOR]
