The committee received the report of the Interim Head of Development Management, including the relevant planning history of the site.

The Development Management Team Leader introduced the report, explaining that the application proposed a variation to Condition 2 of planning permission references 19/00131/VAR and 17/01543/FULM to change the approved glass balustrades to the balconies to compliant metal railings.  The reason for the amendment was due to changes in the Building Regulations to external materials on buildings over 18m high, following the Grenfell Tower fire.  Due to the lamination in the approved glass balustrades, these could not be used on the approved buildings. 

In response to a question from the Chair, the Development Management Team Leader clarified that if building regulations subsequently altered allowing the use of glass balustrades a further application for planning permission would not be required.

Members commented that it was good that building regulations had been amended following the Grenfell Tower fire.  Following a question in this regard, the Development Management Team Leader provided reassurance that it would not be possible for the developer to install the glass balustrades as buildings utilising these materials were not being signed off by the relevant fire officers under the revised building regulations; hence why developers were making subsequent applications.

The Chair moved the officer’s recommendation.

RESOLVED –

That planning permission be granted subject to the completion of a deed of variation to secure the planning obligations contained in the s.106 unilateral undertaking dated 22 March 2018 and the conditions listed below:

1.                  The development to which this permission relates shall be begun before 27^th April 2021.

Informatives

1.                  This development may require a permit under the Environmental Permitting (England and Wales) Regulations 2010 from the Environment Agency for any proposed works or structures, in, under, over or within eight metres of the top of the bank of the River Colne, designated a 'main river'. Some activities are also now excluded or exempt. A permit is separate to and in addition to any planning permission granted. Further details and guidance are available on the GOV.UK website:

https://www.gov.uk/guidance/flood-risk-activities-environmental-permits.

2.         A Groundwater Risk Management Permit from Thames Water will be required for

            discharging groundwater into a public sewer. Any discharge made without a

            permit is deemed illegal and may result in prosecution under the provisions of the

            Water Industry Act 1991. We would expect the developer to demonstrate what

            measures he will undertake to minimise groundwater discharges into the public

            sewer. Permit enquiries should be directed to Thames Water's Risk Management

            Team by telephoning 02035779483 or by emailing

            wwqriskmanagement@thameswater.co.uk. Application forms should be

            completed on line via www.thameswater.co.uk/wastewaterquality."

            Swimming Pools - Where the proposal includes a swimming pool Thames Water

            requests that the following conditions are adhered to with regard to the emptying

            of swimming pools into a public sewer to prevent the risk of flooding or

            surcharging: -

1.         The pool to be emptied overnight and in dry periods.

2.         The discharge rate is controlled such that it does not exceed a flow rate of 5 litres/second into the public sewer network.

            Thames Water would recommend that petrol / oil interceptors be fitted in all car

            parking/washing/repair facilities. Failure to enforce the effective use of petrol /

            oil interceptors could result in oil-polluted discharges entering local

            watercourses.

            Thames Water recommends the installation of a properly maintained fat trap on

            all catering establishments. We further recommend, in line with best practice for

            the disposal of Fats, Oils and Grease, the collection of waste oil by a contractor,

            particularly to recycle for the production of bio diesel. Failure to implement these

            recommendations may result in this and other properties suffering blocked

            drains, sewage flooding and pollution to local watercourses.

            There are public sewers crossing or close to your development. In order to

            protect public sewers and to ensure that Thames Water can gain access to those

            sewers for future repair and maintenance, approval should be sought from

            Thames Water where the erection of a building or an extension to a building or

            underpinning work would be over the line of, or would come within 3 metres of,

            a public sewer.

            Thames Water will usually refuse such approval in respect of the construction of

            new buildings, but approval may be granted for extensions to existing buildings.

            The applicant is advised to visit thameswater.co.uk/buildover.
