Operation Watershed - Key Information and Timeline
• ‘Operation Watershed’ was created by West Sussex County Council (WSCC) following flooding in the county during 2012/13 to address issues with the drainage infrastructure including the riparian ditch network, damage to roads and improving resilience to protect homes, businesses and highways.
• In December 2017 £1.5m was allocated to Operation Watershed over a 5-year period until 2022/23. The budget allocation for 2021/22 is £300,000, available on a first come-first served basis, subject to evaluation using a scorecard.
This project is time-critical both in terms of access to funds and window to complete the work i.e., after the nesting period and before the rainy season – August to October.
March 2019 – the Parish Council explores funding from the South Downs National Park Authority to enhance the biodiversity of the pond, last major works undertaken in 2000.

September 2020 – SDNPA offers to pay for the Quantity Survey Report (civil engineer’s survey).
October 2020 – SDNPA also offers to pay for an ecology report, Arun District Council will fund the topographical survey and CCTV/jetting drainage survey and the Parish Council arranges a silt level and contamination survey at a cost of £2521.30 (+VAT, which can be reclaimed).
The Council is informed that removing the roots of the willow tree will not on its own be sufficient to address highway flooding.
