The impact of shared transport on parking

Amend Planniing Obligation Agreement for developers to reduce parking provison in planning applications for multi-occupancy developments from 1:1 to 1:0.5 or better.

Why the contribution is important

Existing Planning guidelines require developers provide between 1:1 and 1:0.7 car spaces per residential unit.

It is anticipated that ~7,000 new units need to be built before the turn of the decade. Planning Guidelines are therefore almost mandating an increase of ~7,000 vehicles. Until ICE vehicles are banned (at the earliest 2030), these are going to be mostly Co2 emitters.

Vehicles don’t just need a ‘home’ parking space: vehicles move and need places to go to which, in turn, need their own parking spaces.  Research puts car parking space required/ vehicle at a minimum of 3 and a standard benchmark of 5. The 7,000 additional cars would therefore require between 21,000 and 35,000 extra parking spaces to be provided pan-island.

The minimum design standard for a parking space is 4.8m by 2.4m (with a tendency towards larger spaces to accommodate the increasing preponderance of SUVs and other larger vehicles). For 21,000 spaces this equates to 241,920m² and at 35,000 spaces an extra 403,200m². Jersey’s total size is 119,500,000 m².

A mitigating solution is to build fewer parking spaces and migrate car ownership towards shared transport-on-demand, or ‘Mobility as a Service’. Developers can provide residents with access to shared vehicles on demand.
