Photos reveal Western Growth Corridor site floods – but council ‘has a plan’

Some housing would be on raised platforms

New photos show the extent of flooding on land where the City of Lincoln Council plans to build the Western Growth Corridor.

The plans for a new shopping centre, 3,200 homes, primary school and leisure facilities will be decided at an extraordinary full council meeting sitting as the planning committee next Wednesday.

Neighbouring resident Richard Morrant has emailed councillors a series of photographs taken last week which show fields next to the Catchwater alongside Grosvenor Avenue flooded.

“This is not an ‘unexpected event’, there have been no severe weather conditions, but these fields flood just like this three to four times a year,” he said, adding they were still flooded at the time of his email.

“Obviously, along with almost every other Lincoln resident who knows this area, we just can’t understand why with so much more land now available through the new ring road extension you seem to be pushing what must be a very high-risk development?”

The Western Growth Corridor, set to the north of Skellingthorpe Road, is one of Lincoln’s four Sustainable Urban Extensions (SUEs) to allow the Central Lincolnshire area to provide for both housing and employment growth until 2036.

The full proposals include:

  • Up to 3200 homes, with a local centre comprising of retail and commercial units and a new primary school
  • A commercial employment area of up to 20 hectares
  • A regional sport and leisure complex, including a new stadium, health and leisure facilities, a hotel and ancillary food and drink elements

A report before councillors next week acknowledges the site covers a number of high risk flood zones alongside lower risk ones.

It says part of the site is subject to a flood risk in excess of one in 100 years, with risks including tidal, rivers and extreme rainfall, as well as flooding from the breach of flood defences and reservoirs.

However, it said mitigation measures would be in place to tackle the concerns.

Measures include a network of Sustainable Drainage Systems (SuDS), allowing water to be stored and allowed to infiltrate back into the ground, alongside a network of swales – channels designed to catch and direct water into existing networks.

Those networks would also be widened to provide additional space, while green corridors will be created to protect potential flood flow routes.

The housing would be build on raised platforms to ensure it sits above the maximum flood water levels, while ground levels in the northern part of the site would be lowered to create additional wetlands.

The plans have the support of the Environment Agency and Anglian Water has said it has capacity to accommodate the discharge from the development – though is working with the council to identify upgrades and further investment.

“A significant amount of technical work has been carried out,” said the document.

“The Local Planning Authority are given confidence by this support that the development would have no adverse impacts on existing residents and that technical matters have either been dealt with or are capable of being dealt with by condition.”
