surprised i didn't even hear about this until last week from a friend who lives closer that end of the park. Natural Resources Wales / Roath Flood Scheme they're building flood defence walls along the roath brook all the way down from pen-y-lan road, through waterloo gardens and railway gardens at the far end. closures for work at railway gardens start on monday so this weekend is the last chance to see it as it is now. i've been down and filled one memory card today, weather set good for the weekend, hopefully fill another tomorrow. i've no idea how extensive the works will be at that end, friend was talking about losing the far bridge and at least some of the willows along the river.
