Three years ago, a planning application landed at the Castellón provincial council that barely anyone noticed. It proposed draining a small coastal wetland — a protected area under regional law, though the protection had never been rigorously enforced — to make way for a 200-room hotel complex and associated parking. The application was technically compliant with the planning rules as they were written.

What the developers did not anticipate was the neighbourhood association.

The Associació de Veïns del Prat, which had existed for decades as a fairly dormant organisation focused on local amenities, found itself transformed by the planning application into something rather more serious. Within a month of the application becoming public, the association had engaged an environmental lawyer, commissioned an independent ecological survey, and begun collecting signatures.

The Fight

The legal process was slow and expensive. The association raised funds through local events, small donations, and a crowdfunding campaign that attracted contributions from environmental groups across Spain. The ecological survey documented seventeen species of birds using the wetland as a breeding or feeding site, including two that are classified as vulnerable under Spanish law.

The provincial council rejected the application on the first review. The developers appealed. The appeal process took eighteen months. Last month, the regional court upheld the rejection, citing the ecological survey and finding that the original planning assessment had failed to adequately consider the protected status of the site.

What Comes Next

The association is now pushing for the wetland to receive formal nature reserve status, which would make any future development application significantly harder to pursue. The regional environment department has indicated it is open to the proposal, though no timeline has been set.

"We didn't set out to become environmental campaigners," said the association's president, a retired schoolteacher who has lived in the area for forty years. "We just didn't want to lose something that we thought was worth keeping."
