Agree 100%. They've systematically ruined the W/NW side of Preston. No proper infrastructure being provided, schools, doctors, community areas ..... roads as they were before the houses etc etc.
And as you say there will be problems when we get rainfall like yesterday.
Just to add to what i was saying before i've found the river data :
River level information for River Ribble at Samlesbury - GOV.UK
FLOOD-WARNING-INFORMATION.SERVICE.GOV.UK
Check your risk of flooding: get current flood warnings, river and sea levels, check the 5-day forecast or use flood risk maps
