Rectory Road and Sycamore Road Flood Alleviation Scheme
- Latest Updates
-
The Rectory and Sycamore Road flood alleviation scheme was carried out between 2021 and 2022.
The objectives of the scheme were to:
- Improve the resilience of the local area to winter flooding
- Reduce the negative effects of flooding on residents' homes
- Improve the resilience of critical infrastructure in the area.
Scheme overview
Rectory Road
- Repairing, replacing and amending bunds
- Improvements to existing pipework and gullies
- Construction of new overflow system
- Re-instatement of historic ditch
Sycamore Road
- Reinstatement and creation of new bunds
- Install additional gullies to improve connectivity
- The works in detail
-
Phase one of the works was carried out at Rectory Road and started with the reprofiling of the historic ditch in May 2021. The works were delayed from January 2021 due to the discovery of fly tipped material, including some asbestos tiles, under the vegetation in the ditch, however this was successfully and safely removed.
The clearance of existing highway pipework and gulleys was also carried out in Spring 2021 and landscape works within the Blackwater Valley to improve the surface water flow path to the River Blackwater was ongoing. The scope of the scheme changed slightly from the one shown at the public exhibition (see below) in that the bunding has been removed.
The 2nd phase of the works at Rectory Road, completed in February 2022, involved laying a surface water pipe from the playing field, via the car park by the bridge, to join the main surface water pipes on the north side of Rectory Road, which drain into the railway line ditches. The connection to the railway drainage system will be made by the newly cleared historic ditch. The water that emerges from the side of the railway embankment onto the eastbound footway will be intercepted before going under the railway bridge.
Phase 3 of the works were at Sycamore Road. They were substantially carried out in 2022. The works included the raising of a 50m long section of footpath to provide storm water storage inside the King George V playing fields, the creation of low earth bunds along the boundary between the playing fields and the road, and provision of new drainage outlets into the existing surface water drainage system.
- Scheme background
-
Hampshire County Council has been working closely with Rushmoor Borough Council, the Environment Agency, Thames Water and Network Rail to identify and implement affordable flood risk mitigation measures to address surface water flooding at Rectory Road and Sycamore Road.
Both areas have a record of vulnerability to:
- Surface water; and
- Groundwater flooding after certain prolonged rainfall events
Even though works have been undertaken by Thames Water and Hampshire Highways in the past, there is still a residual risk of flooding at these locations.
- Project approval
-
A project appraisal of the scheme was approved by Councillor Humby Executive Member of Environment and Transport on 20 November 2020.
The report provides an overview of the scheme, estimated scheme costs of around £475,000 and available funding from central government, the Thames Regional and coastal Committee and Hampshire County Council.
