Car parking – How to calculate the parking allocation for a development

The application of maximum parking standards conforms to the requirements of PPG 3, para. 51 and 60; and PPG 13 para. 51.  

The main factor will be accessibility of the site, upon completion, by non-car modes. An indication of current levels of accessibility (before any development-related enhancement) is on the County Council website. As a general rule, areas of high accessibility are served by at least eight buses an hour within 400 metres and good cycling and pedestrian facilities.  Developments in such accessible locations warrant less car parking than is shown under the  maximum parking limit. For more guidance, please refer to your local planning authority.

Several local factors can also influence the calculation of the parking allocation.
For example:

1.  Area of economic regeneration or constraint. Reduced parking will apply in constraint areas while regeneration areas may warrant less reduction in parking.

2. Zone characteristics. Historic town centres, other environmentally sensitive locations, or specific locations that have particular Road Traffic Reduction Act targets will warrant reduced parking allocations.

3. Self-containment. Reduced parking may be justified in highly self-contained areas, while a reduction may be inappropriate where it is less self-contained, eg a location competing with a neighbouring area.

4. Cycle accessibility. Where there is high cycle accessibility planned or in use, reduced car parking will apply.

Other parking in the locality must also be considered.

The calculation of parking spaces to be allocated for a development should take account of two further factors:

1. Existing public parking stock with spare capacity within walking distance of the development site should be included in the overall maximum parking provision.

2. Additional development on a site will mean the entire parking stock being brought into account.

Levels of adjustment in the parking allocation

The reduction in parking allocation varies at different rates according to land use.

Table A: Percentage of parking limit reduction by land use

Where there is most accessibility (for example, close to transport interchanges), zero parking will be encouraged if local circumstances permit.

Minimum cycle parking standards are indicated on the attached tables by land use. It is expected that at least the specified level should be provided. For more details on cycle provision, in particular short- and long-stay facilities, refer to 'Cycle Parking Standards -Appendix 2.’ Generally, for motorcycles – except in residential land uses – one space is to be provided for every 25 car parking spaces.

 

Parking for people with disabilities

Suitable parking spaces should be provided for people with disabilities. Generally, except for residential land uses, disabled people's car parking spaces should be counted as 5% of the total allocation. General advice is included in Parking for Disabled People (Traffic Advisory Leaflet 5/95) published by the DFT. Hampshire County Council's Accessible Transport Strategy and the ‘Movement, Access, Streets and Spaces’ document (July 2001) should also be considered.

 

Heavy commercial vehicles: parking standards

Where required, an operational number of spaces for HCV parking will be considered on the basis of individual application to the local planning authority.

 

Design

The layout and design of car parks should take account of the 'Secured by Design' initiative to reduce crime and maximise personal safety.
