Horsham Park

Horsham Park Pond Project

From summer 2021 until spring 2023 we have been undertaking essential maintenance and improvement work to improve the health of Horsham Park Pond.

As well as being a popular visitor attraction, Horsham Park Pond is an attenuation pond. This means it gathers excess surface water, alleviating pressure and capturing pollutants that may otherwise enter the River Arun.

The pond had become heavily silted, which reduces its capacity for storage. De-silting of the pond is a regular requirement to maintain capacity. In addition, the sluice required repair.

The project has included the dredging and excavation of silt that was deposited in the park, near to the pond for a period of at least nine months to dry out. This was then spread out on-site (to reduce cost and environmental impact) and seeded. We then installed a new fence which included hedgehog holes and new gates.

The first stage of preparation work started on July 26 2021.

All works will be undertaken with as little physical impact and long-term effect on the park as possible.  

There will be no work undertaken at the weekends to minimise visitor disruption.

Planned improvements

The improvement work completed so far includes:

  • selectively removing trees to create gaps in the fringe vegetation allowing more light in and opening up viewpoints;
  • clearing a shrub area on the western side of the pond with a view to re-landscaping;
  • removing the sediment in the bottom of the pond which in the long term will help to improve the quality of the water and the health of the pond for wildlife and biodiversity.
  • repair to the sluice
  • reducing the number of fish, by re-homing the healthy native varieties, which will be beneficial in terms of water quality and biodiversity.
  • installation of the new boundary fence including 'Hedgehog Highway' tunnels.
  • landscape restoration of the removed sediment
  • second stage of selective tree removal and crown lifting

Final work still to be completed includes:

  • new planting schemes
  • aesthetic improvements to the duck feeding area, central path and new signage.
