Overview
- The first-phase Patricova revision was published this week in the DOGV and opens a 20-business-day public information period while notifications were sent to affected municipalities and the Confederación Hidrográfica del Júcar.
- New technical mapping increases the flood-prone area in the dana-affected zone from 27,162 to 43,779 hectares, defines seven hazard levels, and models 25-, 100-, 500- and 2,000-year return periods.
- The plan ties hazard levels to concrete planning rules that require raising ground floors to flood cotas, favoring taller housing, banning underground parking in medium-risk areas, and prohibiting certain construction in the highest-risk zones.
- IIAMA at the Universitat Politècnica de València based the update on 11,720 pluviometer records and hydraulic modelling and proposes about €1,428.35 million of 46 named hydraulic interventions across the affected basins.
- Implementation faces a major governance gap because only 12 of 74 evaluated municipalities have adapted their General Plans to Patricova, so municipal plan changes and funding decisions will determine whether mapped risk and technical measures actually reduce future harm to residents.
