Decision Notice

CONDITIONS:

1 The development hereby permitted shall be begun before the expiration of 3 years from the date of this permission. Reason: In accordance with the requirements of Section 91 of the Town and Country Planning Act 1990 (as amended by Section 51 of the Planning and Compulsory Purchase Act 2004).

2 The development hereby permitted shall be carried out in accordance with the following approved plans: 2900/1 2900/2, 2900/3 Reason: For the avoidance of doubt and in the interests of proper planning.

3 The development hereby permitted shall not be commenced until surface water disposal works serving the development have been completed in accordance with details that have been submitted to and approved in writing by the Local Planning Authority. These works shall not thereafter be altered or removed unless otherwise agreed in writing by the Local Planning Authority. Reason: To avoid flooding and in the interests of water quality and the residential amenities of future occupiers and in accordance with the aims and intentions of policy 3 of the Cornwall Structure Plan 2004 and policy GD-4 of the Penwith Local Plan (2004).

4 All works, including ground clearance, levelling and excavation shall be carried out in accordance with the recommendations contained within British Standard BS 5837:2005 - Trees in relation to construction. Reason: To ensure the protection of trees throughout the the duration of the proposed development works.

5 No development shall commence until details of the roof slates and method of fixing have been submitted to and approved in writing by the Local Planning Authority. The development shall be carried out in accordance with the approved details and retained as such thereafter unless otherwise agreed in writing by the Local Planning Authority. Reason: To preserve and or enhance the character of the adjacent Listed Building (Carwin Villa)

REASON(S) FOR APPROVAL:

The principle of residential development at this site has already been established, the proposal thus accords with policy H-6 of the PLP (2004). The design of the proposed property is in-keeping with the character of the local built environment and would not significantly impact on the character or appearance of the grade II Listed Building to the immediate west of the site. The development thus accords with policies 1, 2 and 10 of the CSP (2004) with policies GD-1, GD-2, TV-1 and H- 18 of the PLP (2004) and government guidance given in PPS1, 3 and 5. The site lies within a designated critical drainage catchment and a suitable planning condition has been included in the planning approval in order to ensure that offsite flood-risk is not increased as a consequence of the development; the proposal thus accords with policy 3 of the CSP (2004), policy GD-4 of the PLP (2004) and government guidance given in PPS25. There is adequate parking to serve the development and there are no objections to the proposal from the Highways Officer, the proposal thus accords with policy GD-5 of the PLP (2004). There are a number of large trees at the rear (north-west) of the site which are considered to be of high amenity value therefore a condition has been included to ensure that these are not damaged during the construction phase of the development as was also the case in the earlier (2009) approval.

ANY ADDITIONAL INFORMATION:

• Critical Drainage Areas B2-B3 - Development of 1- 3 dwellings - Following the Building Regulations Drainage hierarchy, surface water should:-
i. Drain to a soakaway or infiltration system designed in accordance with the SUDS Manual - CIRIA C697, using a minimum of a 30-year return period storm. Where an FRA demonstrates that infiltration is not possible:-
ii. A sustainable drainage system should be provided discharging at a rate not exceeding 1.5 litres/second per dwelling, with attenuation provided up to the 30- year storm. (Products exist that allow individual properties to restrict run-off to this rate, using private underground storage tanks. A discharge of 1.5 litres/second is typically achieved on the commercially available systems using a proprietary device on the outlet with an orifice of around 30mm. This is combined with a sediment trap and a filter to prevent blockage. Storage is provided on the property in an underground tank or crate system, operating with a maximum depth of water of approximately 500mm. The size of the tank will need to be based on the impermeable area draining to the system. It should be noted that due to the small orifice size these systems would remain in private ownership as they are unlikely to be adopted.)

- The design must take into account the appropriate allowance for increased rainfall from climate change, based on the lifetime of the development, the guidance in Annex B of PPS25 and the PPS25 Practice Guide. This is currently an increase in rainfall intensity of 30%.

- Safe and appropriate flow routes from blockage and exceedance of the drainage system must be evaluated. This must demonstrate no property flooding or increase in flood risk either offsite or to third parties.Version 2 January 2010, Drainage Guidance for Cornwall Council Page 13.
