The council received a total of 370 letters of objection, a petition containing 237 signatures as well as objections from a range of community, heritage and environmental groups, including the Campaign for the Protection of Rural Wales.
The council said it had had nine letters of objection, including complaints from the South Hill Residents Association that the new pier would obscure the sea view, the extra height would mean it overlooks houses and it had the potential to create extra noise.
