The Eco-Boulevard and the Water Arena for the Lazzaretto quartier, Bologna (BO - Italy)
Chosen SuDS solution
Swales, bioretention systems, urban detention basin
Peculiarity
IRIDRA's proposal for the Climate Change Adaptation of the Bologna Municipality, included in the technical assistance given to Atkins in the study "Climate Change Adaptation and Resilient Cities" (financed by the European Investment Bank -EIB). These proposal were included in the new guidelines of Bologna Municipality for SuDS systems, one of the action of the Bologna Climate Change Adaptation Plan developed under the BlueAP LIFE project

Sustainable drainage systems in Sesto Ulteriano (Metropolitan City of Milan - Italy)
Chosen SuDS solution
Bioretention systems, urban detention basins
Peculiarity
IRIDRA SRL design proposals in the feasibility study jointed with Majone and Partners Engineering Studio Gioia Gibelli, and Studio Idrotecnico for SuDS retrofitting of an industrial and urban catchment in Sesto Ulteriano, including retrofitting intervents along roads, parking lots and industrial sites.

Retrofitting SuDS of BEN-ESSERE quartier, Bresso (Metropolitan City of Milan - Italy )
Chosen SuDS solution
Bioretention systems, wet swales, dry detention basins in urban park area
Peculiarity
Within the framework of urban desealing
interventions with SuDS, it was taken the chance to design multipurpose elements able to also provide urban restoration of the BEN-ESSERE (wellness) quartier of Bresso. The design followed a "Water Sensitive" approach, infiltrating road runoff, and conveying road runoff overflow and roof runoff by a swale towards a detention basin within the urban park "Parco Nord", where volume control strategy according to local legislation (Reg. RL 07/2017)
is provided.
Year of design
Preliminary design, 2021

Chosen SuDS solution
Bioretention systems, urban detention basins
Peculiarity
Within the framework of urban desealing interventions with SuDS, it was taken the chance to design multipurpose elements able to also provide urban restoration.
Year of design
Preliminary design, 2021; Detailed design ongoing

Retrofitting SuDS area Mercato presso via Paganini, Bovisio Masciago (MB)
Chosen SuDS solution
Bioretention systems with trees, urban detention basins
Peculiarity
Within the framework of urban desealing interventions with SuDS, it was taken the chance to design multipurpose elements able to also provide urban restoration of the market area, currently fully impermeable and without green spaces
.
Year of design
Preliminary design, 2021; Detailed design ongoing
