30 BUILDING-IN RESILIENCE: REVISITING FLOOD MITIGATION FOR NEW DEVELOPMENTS INDUSTRY VIEWFINDER
Do you think future housing standards should require specifi c SuDS or stormwater management features? Yes No Depends on Location
on emerging products and technologies for fl ood and surface water mitigation approaches. Participants were asked whether they stay up to date with advances in u-related products, including improved permeable paving systems, modular underground storage, smart rainwater harvesting technologies, and real-time fl ood monitoring systems. he inclusion of these uestions refl ects the increasing role of technological innovation in delivering smarter and more adaptive water management infrastructure. espondents were asked to assess their confi dence in the performance of various stormwater management systems, including permeable paving, blue and green roof systems, modular storage systems, swales, wetlands, non-return valves, and tree pits. ome of this confi dence or lack of it, could stem from a lack of experience, or received ideas, and potentially greater education will have a large role in tackling this. The established standard solutions of permeable paving and modular underground storage saw good fi gures and of respondents very confi dent, however blue and green roofs only garnered 7%, and even swales and wetlands only managed
20%. Clearly, there is more to do to educate the sector on their respective merits.
DESIGN & INSTALLATION CHALLENGES
Installation challenges remain a major barrier to widespread uptake of resilient drainage measures. The survey therefore investigated which systems respondents have installed in practice and what aspects they found most diffi cult. Common challenges include maintenance responsibilities, upfront capital costs, design integration, space constraints, and navigating planning approval processes. Unsurprisingly, upfront costs were out in front with 62%, but available space was a major blocker for many, with 52% choosing them, as well as planning approval (48%), maintenance requirements (45%), and integration of products into designs (39%). Participants were also asked how frequently they encounter a selection of perceived barriers such as lack of client interest, limited supplier availability, or confl icting planning requirements. Client interest was an issue, but ‘high capital costs were cited by , as well as insuffi cient long-term
