Improvement Project Update 22 March 2017

We are currently busy on site working on a series of improvements –

  • The Lake – The dirtiest job of the lot! The lake has been drained in order to remove a large amount of silt which has built up over the years.  Where possible we are spreading the silt within the park to improve planting conditions.   This will continue for another week until we allow the lake to refill through rainfall and natural springs.  warren Lake de-siltSome of the wildfowl have flown off but a pair of mallards have remained throughout and frogs have been continuing to breed.  Once the de-silting has finished the iris and waterlillies will be planted and once water is back in the lake a series of three aerators will be installed.
  • Boardwalk and footpaths – two companies have been appointed to deliver these works following a full procurement process.  The boardwalk will be constructed of recycled plastic.  Once the boardwalk is installed the path network will be upgraded and topped with a mix of stone and rubber which means it is flexible and less likely to crack in the future - 1212 recycled tyres will be used on these footpaths!
  • Trees - new trees have been planted in the garden including the large MFG treesChristmas tree at the High Road entrance.  Also planted is a magnolia which is already starting to come into flower, a beech around the lake and a Japanese Maple which will soon provide a shot of shrimp pink in the garden when the leaves unfurl.  A weeping purple beech is also due to be planted within the next week. 


  • Hedges - 300 beech trees have been planted around the perimeter of the garden area to provide a new permanent boundary hedgeline.MFG hedge


  • Planting – Tidying up of the existing beds has been completed and a number of shrubs and roses already purchased with more on the way.
  • Wildflowers – 155m2 of wildflower turf has been laid at the High Road and Warren Road entrances meadows containing a mix of 34 UK native wildflowers and grasses, with the addition of approximately 15 non-native perennial flowers.


More details can be found on the attached plan.

The project is being funded through section 106 contributions received by the council from local developments.

In order to carry out the works, the site is currently closed for public access and will remain closed for the duration of the improvement project.
