Wave Surface Hard Constraints
Welsh Government
These layers represent hard constraints on the development of the wave energy (surface) resource within the Welsh National Marine Plan area. A hard constraint refers to a spatial consideration (such as existing activities or infrastructure) that effectively prevents new development for a specific sector. These hard constraints layers were used as part of work to refine the Wave Energy Resource Area, so that any areas covered by hard constraints were excluded from the Wave Energy Refined Resource Area.
