Save the Norfolk Park 11
We call on the Council to save the “Norfolk Park 11” trees.
Why is this important?
Between August 2012 and December 2016 Amey the Council contractor felled over 4200 trees across Sheffield. Now they are planning to chop down 27 of our local street trees. Some of these trees are near the end of their life and should be replaced, many others are mature healthy trees that help to keep the air clean (1), protect our homes from flooding (2) and provide a habitat for local wildlife (3), as well as making our streets nicer and healthier places to live (4). Mature trees are particularly good at filtering out pollution (5), cooling the air in summer (6) and maintaining nature's delicate balance (7).
Four of the trees are said to be damaging the pavement and are therefore discriminatory to disabled people and those using pushchairs. We believe the damage is minor and does not impair accessibility for disabled people, or the users of prams and pushchairs. Alternative highway engineering specifications (8), such as use of flexi-pave and/or pavement restructuring near trees, with kerb stones sculpted to accommodate roots, would represent a sustainable solution to the perceived problems.
The other trees are said to be diseased or dangerous. Our experts say with sensible management and in some cases some pruning, the following 11 trees will thrive for many years and should be saved.
Seabrook Rd/Stafford Road healthy mature sycamore (“damaging”)
Tylney Rd healthy mature sycamore at no.7 (“damaging”)
52 Park Spring Drive - mature healthy cherry tree (“disease”)
76 Park Spring Way - mature healthy sycamore (“dangerous”)
Opposite Norfolk Community School, Guildford Avenue – 2 mature whitebeam trees. (“dangerous/disease”)
Norfolk Park Road 3 Horse Chestnuts grouped together near Sheffield College (“dangerous/disease”)
Holdings Road (outside nos.7 and 31) Cherry Trees (“damaging”)
The Council carried out a survey of households to see if people wanted to save the trees. This was deeply flawed as many houses and in some cases whole streets were missed out.
