Am I at risk of flooding?

Scheme Overview

The proposed Natural Resources Wales scheme will extend along the banks of the and Crindau Pill between the south down to the London to line.

The scheme will be made up of multiple components, including walls, embankments and ground raising. Following careful consideration of the feasibility, costs, benefits and impacts, the preferred option is to construct the new defences to provide protection against a 1 in 200 year event, including an allowance for effects of climate change over the next 50 years. The design will also be adaptive, so that it can more easily be ‘topped up’ in the future if required.

New trees and shrubs will be planted to provide colour and wildlife benefits. Construction of the wall will require the removal of the boundary 4 hedge and several trees, as well as changes to the existing entrances to the allotments. An access ramp for vehicles and pedestrians will be built next to the basketball court.

July 2014 Natural Resources Wales plan to Detailed design work starts finish working on the detailed design for the scheme and then submit a planning application to Newport November City Council in mid-December 2014. Public exhibition 2014 This is one of several permissions required to enable the scheme to be December built. 2014 Planning application submitted to We hope to secure planning permission by April 2015 after which we will tender for and appoint a contractor to build the scheme. Once April all permissions have been obtained, 2015 and a contractor appointed, work Planning permission granted on constructing the scheme can then begin. We currently anticipate Summer construction would start in late 2015 and take 12 to 18 months to 2015 Contractor appointed complete.

Did you know Have you Do you support Do you have any Do you think How can we Crindau is at flooded before? the scheme concerns with the scheme improve on the risk of flooding? design we’ve the scheme? will enhance or design? presented here? threaten the character of Crindau? A number of enhancements will be delivered alongside the scheme. These include cycleway improvements, a new amenity area, seating and bird and bat boxes.
