Appendix A

Information related to predicted housing numbers.

This Strategy has been prepared to mitigate approximately 147,500 new dwellings estimated to be planned between 2024 and 2050 within the 5.6km zone of influence. This equates to 5,674 new dwellings per annum. This estimate is derived from work undertaken with each of the Local
Planning Authorities within the Bird Aware Solent zone of influence.

Each area analysed projections within their adopted and emerging Local Plans and made an assessment of the average number per annum over the planned period. This figure was then multiplied by 26 to cover the period until 2050. The resulting figure was then critically assessed by each Local Planning Authority, using local knowledge of planned development sites and land availability within their boundaries. From this work, a refined figure was presented to the Partnership for each area.

This resulted in the overall figure across the Strategy area of 147,500 new dwellings. A further technical ‘sense check’ was undertaken of this total figure, by comparing it to an estimated overall housing need figure for the same area. (This is based on the Government’s standard method
figure, and the likely split of this figure where a district is partially within the Bird Aware Solent zone of influence*). This comparison between the estimated planned figure and the estimated need figure over the overall Bird Aware Solent zone of influence indicates that the 147,500
figure and subsequent calculation of mitigation costs per dwelling provides a robust basis for the  Strategy.

* Informed by the need split in the PfSH Spatial Position Statement (which covers a similar area) and further consideration of the
figures for the non-PfSH areas.

Appendix B

Further information relating to developer contribution levels.

Application type
Residential annexesThese should be treated like an extension to an existing dwelling therefore mitigation is not required.
Gypsy, traveller and travelling showpeople sitesApplications of this nature are treated as increases in residential development therefore are required to provide the full mitigation consistent with a dwelling.
Alteration in both bedrooms and dwelling from original permissionThe number of bedrooms is only relevant once net increase in number of dwellings has been determined. Therefore, the developer will need to pay an additional contribution for the net increase in the number of dwellings.
House in multiple occupancy (HMO) [UPDATE AGREED 2025]Mitigation would need to be provided for permissions for new HMOs, (excluding change of use from existing C3 (dwelling house) to C4 (small HMO). Mitigation will need to be provided for increased occupancy of an existing HMO to within sui generis (large HMO). If the resultant HMO is C4 the number of bedrooms for that property is used to calculate the contribution in line with that for C3 dwelling houses as set out in table 2. The whole property is treated as one dwelling. If the resultant HMO is classed as Sui Generis each additional bedroom over and above 5 bedrooms is charged at a rate of £335 per bedroom in addition to the 5 bed rate. For example an 8 bed HMO (Sui Generis) would be charged £1,207 + (3* £335) = £2,212. Annual Inflationary increases will apply to the £335 per bedroom rate. Offset from existing C3 or HMO use will be calculated in the same manner as set out above paragraphs and table 2.
Holiday accommodation - caravansMitigation is required and the flat rate should be used, based on the nature of this kind of development. For holiday sites there should be a pro-rata reduction for conditioned closed periods if this is relevant. In the event that details related to bedroom numbers are provided, these would be charged against the sliding scale (and again made pro-rata if appropriate).
Holiday accommodation - tentsMitigation is required and the flat rate should be used, based on the nature of this kind of development. For holiday sites there should be a pro-rata reduction for conditioned closed periods if this is relevant. In the event that details related to bedroom numbers are provided, these would be charged against the sliding scale (and again made pro-rata if appropriate).
Holiday accommodation – summertime onlyMitigation would be required for holiday accommodation which is only used during the summer breeding months. The summer fee rate should be used and with a pro-rata reduction for conditioned closed periods. Only in this instance, the summer scale of 40% would apply.
StudiesStudies on a bedroom floor are treated as bedrooms. Any room on a ground floor with an en-suite bath/shower room is considered a bedroom.
Outline planning application – number of bedrooms unknownA formula will be added to the S106 agreement so that collection of developer contribution will be taken once the mix of bedroom numbers is known. Furthermore, for the certainty required for the Habitats Regulations the number of beds within the mix will need to be specified.
Temporary permissionsIt is considered reasonable that the applicant should only be required to pay mitigation for the period that their permission lasts. As the Strategy is based around an understanding of in-perpetuity being 80 years, it is therefore logical that the applicant should pay one 80th of the fee for each year the permission is requested for. In these cases, if the bedroom number is known, then use the sliding scale, if not, then the flat rate should apply. The calculation if it is only for a proportion of the year can also be calculated on a pro-rata basis.
Temporary accommodationMitigation is required for this kind of development as the use is residential. The scale should be determined in the same way as residential development, with the 1-bedroom rate used for single bed units, the 2-bedroom rate used for 2 bed units and so on.
HotelsIt is likely that mitigation is required from all hotels as the type of user cannot be determined through the planning process. Any proposed bespoke approach should be discussed with the relevant planning authority and Natural England at the pre-application stage.
Older person housing – assisted living/retirement housing/ sheltered housing/extra care/ close care (C3)Mitigation is required for this kind of development as the use is residential. The scale should be determined in the same way as residential development, with the 1-bedroom rate used for single bed units, the 2-bedroom rate used for 2 bed units and so on.
Care homes, Care homes which include nursing provision and Nursing Homes (C2)Care facilities classed as C2 will need to be assessed on a case-by-case basis with the determining planning authority and Natural England as to whether contributions are required and what the scale of mitigation should be.
Self-contained student accommodationThese will need to be assessed on a case-by-case basis with the determining planning authority and Natural England. In recognition of the general absence of car parking and the inability of occupants to have pets, there are times when a reduced rate is applicable. If a reduced rate is used, the general model is that every 5 study bedrooms will be considered a unit of residential accommodation and charged accordingly (that is, 50% of the rate of the 5-bedroom property charge).
