The proposal for using Sims Hill as a site for a new park and ride seems a poor choice.
The land itself is fertile & used to grow food for residents of Bristol. It has high quality, productive soil. The selection of this site seems contrary to both Bristol council strategic policy (p.73, Bristol Development Framework Core Strategy) and WECA guidance (which is to minimise loss of productive land when building housing - why would this not be applied to transport?).
Secondly, the location itself is poor for a park and ride. Traffic backs up on the M4 entering the M32. This would imply a site accessible directly from the M4 is necessary to actually reduce congestion. A site near Emersons Green or the Bristol & Bath cience park seems more suitable, especially given the light industrial use in the area (e.g. distribution warehouse off Jenner Boulevard, Puma energy off Folly Brook). This would enable the park and ride to connect directly to the M4 reducing congestion on both M4 and M32 and connect into the metrobus system.
