5.2Dwellings without on-plot parking5.2.1 Provision of communal car parking
Where parking is provided, designated accessible parking bays (see 5.2.2) forblocks of flats or individual houses without on-plot parking should be providedon the basis of at least one such bay in each parking location and/or lift coreassociated with that development,plus additional bays distributed across theavailable parking locations. The design should not preclude the possibility ofsome parking bays being increased in size to become accessible bays in thefuture.
NOTE 1 The provision of car parking bays in a residential scheme is determined bythe local planning authority.Refer to the parking standards policy in the relevantlocal development plan (see Annex A for information on car park management).NOTE 2 lt is desirable to provide a charging point for electrically powered mobilityscooters (see also 13.7).
NOTE 3 In basement car parking areas the constraints imposed by structuralcolumns might preclude the provision of larger bays at a later date unless heflexibility of layout is considered within the initial design.
Where the parking location is a large basement served by a number of lift cores,at least one designated accessible parking bay should be located adjacent to
each lift core.
NOTE 4 ln this context, a parking location might be an enclosed car park (e.g. in a basement, undercroft or podium), an off-street parking court or an on-street bank ofparking, whether in a parallel, angled or right-angled formation. Guidance on car parking design and location is given in Car parking – What works where  andManual for streets .
where some dwellings in a development are designated as “wheelchair
housing” , any specific parking provision for such dwellings should be in additionto the recommendations above.
NOTE 5 A small proportion of wheelchair users have high-top conversion vehicles
which can require a vertical clearance of at least 2.6 m from the carriageway.Furtherguidance on clearance heights is given in BS 8300:2009+A1,4.3 and 4.4.3.Guidance
on barrier control systems,and the controls and vertical clearances of any vehicleheight barriers, is given in Bs 8300:2009+A1，4.4.2 and 4.4.3.
NOTE 6 For access routes from car parking spaces, see 6.3.
5.2.2Designated accessible parking bays
Designated accessible parking bays should be at least 3.6 m wide x 6.6 m longfor parallel on-street parking, and at least 3.6 m wide x 6.0 m long for enclosedcar parks, off-street parking courts and angled or right-angled on-street parkingfaciiities.
NOTE 1 Parallel, angled and right-angled parking refers to the configuration of thelonger dimension of the bays relative to the kerb and direction of the carriageway.
NOTE 2 Markings for designated accessible parking bays are shown in the
following figures in Bs 8300:2009+A1:
on-street parking bays (see Bs 8300:2009+A1，Figure 1);. off-street parking bays (see Bs 8300:2009+A1，Figure 3).
5.3 Setting-down points A setting-down point should be provided on firm and level ground. The distance from the setting-down point to an individual house or the communal entrance of a block of flats should be as short as practicable but not more than 50 m, and the gradient of the route should conform to 6.1. NOTE For further details about setting-down points, see BS 8300:2009+A1, 4.5.
6 External access routes COMMENTARY ON CLAUSE 6 An accessible route is essential to a dwelling or communal entrance, from facilities such as car parking and setting-down points, and from the site boundary where there are existing pedestrian routes that might give access to the site. It is preferable for all routes to be accessible, including access routes to garden areas, play spaces and amenity spaces. Particular attention needs to be paid in gated developments to ensure that pedestrian access and egress is accessible to all users. When designing an approach to a building, it is important to recognize that changes in level are difficult for many people to negotiate, including wheelchair users, people who need to use walking aids and individuals with impaired sight. It is important to reduce the risk of injury to people, particularly individuals with impaired sight, when approaching and passing around the perimeter of a building under all lighting conditions. Residents with visual or memory impairment will be helped if there are permanently detectable and noticeably recognizable physical features to provide familiar waymarks when moving along access routes around their homes. Further guidance is given in the Thomas Pocklington Trust guide Housing for people with sight loss . Guidance on dropped kerbs and tactile paving can be found in the DFT/DTLR publication Guidance on the use of tactile paving surfaces .
