The ‘alternatives considered’ are measures that have been identified by either policy makers, stakeholders or the public – some of which may have merit in addressing some of the M4 CEM objectives. However, following detailed analysis and consideration as part of the packaging of the possible measures; these ‘alternatives considered’ fall outside of the M4 CEM Programme, for a number of possible reasons. The Lagoon measures fall into two categories: Barrage 1. Those that will help towards meeting the objectives but could be delivered by others outside of the Junction Highway M4 CEM Programme; and closures upgrades 2. Those which have been discarded due to poor performance against the M4 CEM Programme objectives. What will happen to the measures falling outside of M4 CEM that are still good ideas? Policy Climbing Each measure’s Appraisal Summary Worksheet sets out an action for the Welsh Government. Whilst poor measures lanes performing measures may not be pursued; those that have merit will be passed onto the relevant potential delivery bodies for consideration. It is important to Welsh Government that these measures that have some merit in helping address the wider transport problems in South Wales will not be lost. Therefore this Workbook will be used to raise these ideas and help join up thinking between different Welsh Government departments and other potential delivery bodies.
