Scenario 1: on-site requirements are met in full
| Development provides this amount of space for outdoor sport and open space on-site, in line with policy requirements. The detailed break-down is as follows: |
5,414.75 sqm in total |
This is policy compliant |
| Outdoor sport | 4,252.50 | |
| Children's playing space (equipped) | 55.25 | |
| Allotments and Community Gardens | 243.00 | |
| Formal Open Space | 283.50 | |
| Informal and Natural Open Spaces | 283.50 | |
| Amenity Greenspace | 297.00 | |
| The above outdoor sport and open spaces are then transferred to and adopted by the Council and the developer pays the Council a commuted maintenance sum of: | £69,075.10 |
Scenario 2: on-site requirements are met in full, with variation to the mix of open space types
| Development provides this total amount of space for outdoor sport and open space on-site. However, the breakdown of each type of open space is different that the indicative standards. (Fill in the red boxes below with your estimated provision for each type to check if it meets the total quantum required) | 9,385.00 sqm in total | This appears to meet the quantum required, however, the types of space and quantum of each type needs to be agreed by the Council |
| - | comprising of: | |
| Outdoor sport | 5,500.00 | |
| Children's playing space (equipped) | 85.00 | |
| Allotments and Community Gardens | - | |
| Formal Open Space | 1,800.00 | |
| Informal and Natural Open Spaces | 1,000.00 | |
| Amenity Greenspace | 1,000.00 | |
| The above outdoor sport and open spaces are there transferred to and adopted by the Council and the developer pays the Council a commuted maintenance sum of: | £103,940.00 | |
| Alternatively, developer chooses to retain this open space, and it will be maintained by a recognised not-for-profit management | ||
Scenario 3: no on-site provision is made, commuted sum is required
| No on site provision is made, as such developers are required to make this financial contribution for the Council to provide an equivalent amount of the outdoor sport and open spaces to meet the additional demands off-site, and maintain this space | £414,450.60 | This can make development policy compliant. To be discussed with the Council. |
Scenario 4: no on-site provision is made, but demands can be met by improvements to the existing facilities
| No on-site provision is made; however, there is sufficient capacity and provision in the locality to meet the total open space needs of development. In this instance, the Council will require a contribution towards the improvements of such space an | £268,492.00 | This can make development policy compliant. To be discussed with the Council. |
Scenario 5: insufficient on-site provision, remaining demands to be met off-site via a commuted sum
Development provides some space on-site; but it does not meet the requirement in-full, and there is no capacity in the local green space to meet additional demands. (Fill in your estimated provision below).
| Types of space | On-site provision (sqm) | Shortfall (sqm) | On-site provision appears to be policy compliant |
| Outdoor space | 5,000.00 | -747.50 | |
| Children's playing space (equipped) | 150.00 | -94.75 | |
| Allotments and Community Gardens | 500.00 | -257.00 | |

| Amenity Greenspace | 500.00 | -203.00 | |
| Total | 7,650.00 | -2235.25 | |
| In this instance, the developers are required to contribute towards the provision and maintenance of off-site space an amount of: | #VALUE! | ||
| This takes into account any on-site surplus provision against the standards. This amount has been offset: | Not applicable as on site provision appears to have been met |
Scenario 6: insufficient on-site provision, remaining demands to be met via improvements to the existing facilities
Development provides some space on-site; although it does not meet the requirements in full, there is capacity in the local area to meet the remaining demands. (Fill in your estimated provision below).
| Types of space | On-site provision (sqm) | Shortfall, to be met by existing local provision (sqm) | On-site provision appears to be policy compliant |
| Outdoor sport | 5,000.00 | -747.50 | |
| Children's playing space (equipped) | 150.00 | -94.75 | |
| Allotments and Community Gardens | 500.00 | -257.00 | |

| Amenity Greenspace | 500.00 | -203.00 | |
| Total | 7,650.00 | -2235.25 | |
| In this instance, the developers are required to contribute towards the improvements of existing facilities in the local area an amount of: | #VALUE! | ||
| This takes into account any on-site surplus provision against the standards. This amount has been offset: | Not applicable as on site provision appears to have been met |
Scenario 7: insufficient on-site provision, demands to be met via both off-site provision and improvements to the existing facilities
|
Development provides some space on-site; however, unmet demands will have to be met via both off-site provision and improvements to the existing facilities. In this instance, please contact the Planning Development Management Team. The pre-application service allows for an opportunity to discuss the proposed development with the future Planning Officer who will assess your application. |
