When a full-on storm event occurs in Auckland like it did on Monday morning, parks and streets will flood. But in some cases this is by design, says The Spinoff, to lessen flooding risks to buildings, particularly homes, thanks to the marvellous powers of stormwater infrastructure. Next time you wonder why a town centre garden is so expensive to build, the answer may be because it’s not just a garden, it’s also hidden stormwater infrastructure like the setup at Auckland Botanical Gardens.
