For these reasons, in the opinion <strong>of</strong> the Council's Legal Services team the absence <strong>of</strong> reference <strong>to</strong> the<br />

regulations in the heading <strong>of</strong> the TPO is not an impediment sufficient <strong>to</strong> nullify the TPO.<br />

The Helliwell System 2008 was employed in evaluating the visual amenity value <strong>of</strong> the trees considered<br />

for protection within the TPO. This method considers six fac<strong>to</strong>rs; the size <strong>of</strong> the tree, the expected<br />

duration <strong>of</strong> the visual amenity, the importance <strong>of</strong> the trees in the landscape, the presence <strong>of</strong> other trees,<br />

the relation <strong>of</strong> trees <strong>to</strong> their setting and the form <strong>of</strong> the trees. With regard <strong>to</strong> woodland the method<br />

considers the size <strong>of</strong> the woodland, the position in the landscape, the viewing population, the presence<br />

<strong>of</strong> other trees and woodland, the composition and structure <strong>of</strong> the woodland and compatibility in the<br />

landscape. The scores that the Council’s Arboricultural <strong>of</strong>ficer awarded for these fac<strong>to</strong>rs with respect <strong>to</strong><br />

‘A1’ and ‘W1’ can be viewed in full in the TPO file. This method <strong>of</strong> evaluation is considered <strong>to</strong> be a guide<br />

only and not a precise instrument and it is acknowledged that a degree <strong>of</strong> subjectivity is inevitable.<br />

However, having carried out the evaluation the Council’s Arboricultural Officer was satisfied that the trees<br />

in ‘A1’ and in the parcel <strong>of</strong> woodland were worthy protection on amenity grounds and that the risk <strong>of</strong> the<br />

trees being removed made it expedient <strong>to</strong> serve a TPO.<br />

The Oak trees at 16 and 18 <strong>Somersby</strong> Crescent have undergone substantial crown reduction works in<br />

the past and are reforming crowns. Oak trees are a resilient species <strong>to</strong> decay and disease and appear <strong>to</strong><br />

be responding well <strong>to</strong> the previous work. Further information is required <strong>to</strong> fully evaluate the decay<br />

present in these trees, including a climbing inspection and decay tests. It is possible that the ground level<br />

around the Oak in the rear <strong>of</strong> 18 <strong>Somersby</strong> Crescent has been altered and this should also be fully<br />

investigated.<br />

Regarding the claims that the Oak trees are implicated in the damage <strong>to</strong> the properties at 18 and <strong>28</strong><br />

<strong>Somersby</strong> Crescent, it is considered that in both cases insufficient evidence has been provided by<br />

Marishal Thompson <strong>to</strong> substantiate these claims. In order <strong>to</strong> make an informed decision about tree<br />

related damage more detailed information is required such as soil analysis – including pro<strong>of</strong> <strong>of</strong><br />

desiccation, details <strong>of</strong> liquid and plastic limits taken from both a trial and control pit, all moni<strong>to</strong>ring results<br />

preferably for 12 months or more, including level moni<strong>to</strong>ring, borehole sample record and a control<br />

borehole for site soil comparison, full details <strong>of</strong> any drainage report carried out for the property, details <strong>of</strong><br />

any previous underpinning or building works <strong>to</strong> the property, details <strong>of</strong> the damage and location <strong>of</strong> the<br />

damage in relation <strong>to</strong> the trees and heave risk assessment. Arboricultural and underpinning experts are<br />

agreed that level moni<strong>to</strong>ring is the best means <strong>of</strong> determining the cause <strong>of</strong> certain types <strong>of</strong> damage <strong>to</strong><br />

property and this should be carried out at both 18 and <strong>28</strong> <strong>Somersby</strong> Crescent. Should this not be carried<br />

out and a claim is pursued against the Council then the Council reserves the right <strong>to</strong> seek any costs<br />

associated with determining the cause <strong>of</strong> any damage suffered and the extent <strong>of</strong> any necessary remedial<br />

work <strong>to</strong> the extent that these costs are increased by reason <strong>of</strong> the lack <strong>of</strong> level-moni<strong>to</strong>ring information.<br />

Compensation is not awardable in respect <strong>of</strong> making <strong>of</strong> a TPO. The Council would not be liable for any<br />

loss or damage caused or incurred in consequence <strong>of</strong> serving a TPO. The section 203 compensation <strong>to</strong><br />

which Marishal Thompson refers is only applicable where there is a refusal <strong>of</strong> any consent <strong>to</strong> works<br />

under the TPO or the consent has been granted subject <strong>to</strong> conditions.<br />

The serving <strong>of</strong> a TPO does not prevent an application for tree removal being submitted but in this case<br />

all <strong>of</strong> the above information would be required <strong>to</strong> support the application. Anyone can apply <strong>to</strong> undertake<br />

works <strong>to</strong> a tree protected by a TPO, there is no fee levied <strong>to</strong> submit an application for works <strong>to</strong> protected<br />

trees or a limit on applications made. The local planning authority would not unreasonably withhold<br />

consent for tree works which accord with good arboricultural practice, but should consent be refused any<br />

applicant has the right <strong>of</strong> appeal against the decision. The Councils <strong>Tree</strong> Team can provide free<br />

arboricultural advice in future should there be any concerns regarding the protected trees. This service is<br />

not available <strong>to</strong> owners <strong>of</strong> trees that are not protected.<br />

As the trees at 14 and 20 <strong>Somersby</strong> Crescent were removed before the TPO was implemented the<br />

Council would not have been party <strong>to</strong> any details regarding tree related damage. The trees may have<br />

been removed for reasons other than subsidence.<br />
