The new fire declared in Gavà forces 6,000 residents to be confined

In the event of a forest fire in Catalonia, the lockdown of the population is not decided informally, but through the activation of the civil protection plans provided for in the Llei 4/1997 de protecció civil de Catalunya. Once the corresponding plan is activated (territorial, special for forest fires, and the municipal plan), the civil protection authority can order evacuations or recommend lockdown as emergency measures. Citizens have the legal obligation to follow these instructions, and the media must broadcast them as a priority. The State, for its part, can support the Generalitat and municipalities through the State Civil Protection Plan for emergencies caused by forest fires.

Competent authority and plan activation

According to the Llei 4/1997, the civil protection authorities are, in general, the minister responsible for civil protection and the mayors. The law emphasizes that measures affecting citizens' rights can only be adopted once a civil protection plan activation has been declared, and its deactivation must also be formally declared.

In Catalonia, there are:

• Territorial plans (Catalan and municipal), which generally foresee emergencies in their scope (art. 17 of the Llei 4/1997).
• Special plans for specific risks, including forest fires, declared of interest to Catalonia (art. 18).
• Municipal action plans, which must incorporate the provisions of the special forest fire plan.

In municipalities without a civil protection plan, art. 10.3 of the Llei 4/1997 establishes that it is the mayor's responsibility to declare the emergency situation and adopt the measures in arts. 8 to 11.

Lockdown vs evacuation: legal measures

Once the plan is activated, art. 9 of the Llei 4/1997 lists the emergency measures for the population that the civil protection authority can adopt, including:

• Evacuate or remove people from danger areas (evacuation).
• Recommend the confinement of people in their homes or safe places, according to the plan's provisions.
• Restrict access to danger or operation zones.
• Limit or condition the use of services and consumption of goods.

The relevant legal difference is that evacuation involves moving the population out of the risk zone, while lockdown means keeping people in places considered safe, following the plan's instructions. Both are emergency measures adopted under the same legal framework.

Obligations of the population and municipalities

Art. 8 of the Llei 4/1997 establishes that, once a civil protection plan is activated, citizens are obliged to follow instructions and comply with orders from the plan authority, and that restrictive measures must be proportional and last only the strictly necessary time.

Additionally:

• Art. 4: right to receive broad, precise, and effective information about risks and conduct to follow.
• Art. 6: duty of collaboration of citizens with civil protection tasks.
• Art. 7: obligation of self-protection for certain activities and at-risk centers.

Municipalities, for their part, must prepare basic and municipal action plans (arts. 17-18 of the Llei 4/1997) and integrate the special forest fire plan into them. The Llei 5/2003 de prevenció d’incendis forestals strengthens this municipal role by requiring the delimitation of urbanizations, nuclei, and buildings in forest areas (art. 2) and the application of preventive measures, conditioning prior planning for any lockdown.

Communication and inter-administrative coordination

Art. 11 of the Llei 4/1997 obliges media outlets, public and private, to collaborate with civil protection authorities and to broadcast information, warnings, and instructions in emergency situations as a priority and free of charge, always indicating which authority issues the communication. Official orders of lockdown and evacuation are communicated through these channels.

At the state level, the State Civil Protection Plan for Emergencies Caused by Forest Fires establishes the organization and procedures for the State's resources to ensure an effective response from all administrations when national interest is present and to support the plans of autonomous communities when requested or when they lack sufficient capacity. This allows scaling the emergency and reinforcing regional and local devices if the forest fire demands it.

Other related regulations

Within this general framework are also integrated, among others, the resolution of the State Forest Fire Plan, the Royal Decree 893/2013 on Basic Forest Fire Directive, the state regulation of senior technician in emergency coordination, the emergency technician title, the Royal Decree 624/2013, the Law 21/2015 on Forests and the Law 43/2003 on Forests, as well as Catalan and state civil protection, aid, and training regulations: Ordre PRE/130/2023, Ordre MAH/360/2005, Decret 123/2005, Decret 377/2000, Ordre ENS/99/2018, Ordre ENS/320/2016, Ordre ENS/264/2016, Decret 62/2010, Ordre INT/202/2017, Decret 291/1999, Decret 37/2015, Decret 27/2001, Llei 29/2002, Llei 6/2015, Llei 4/2012, Llei 5/2011, Llei 2/2014, Ordre ACC/100/2023, Ordre ARP/199/2025, the state Law 5/2003, the Royal Decree-law 15/2022 on forest fires, and various jurisprudence and academic plans linked to civil protection and fire management (UdL master 2023, UCO master 2022, UdL master 2015, UVic PRL master, STC 58/2017, UOC PRL master 2017, UOC ICT security master, UOC 2011 PRL resolution, RD 1085/2020, Law 4/2024, Law 10/2006, Law 19/2011, UCAV 2003 resolution (forestry), UCAV 2003 resolution (agricultural), UAM 2001 resolution, UCLM 2000 resolution, appeal 6305-2021, appeal 5542-2021, appeal 1690-2017, appeal 1004-2004).

In Catalonia, the competencies and functions of civil protection are structured on a dual framework: the state Law 17/2015 of the National Civil Protection System and, at the regional level, the Llei 4/1997, de protecció civil de Catalunya. The state law sets the basic principles of the system (prevention, planning, coordination, and restoration of normality) and the Catalan law develops how these functions are organized and exercised in Catalonia's territory. The Llei 4/1997 defines civil protection as a public service aimed at protecting people, property, and the environment against serious collective risks, disasters, and public calamities, detailing actions of anticipation, prevention, planning, intervention, and recovery. Additionally, it establishes its own organizational structure (territorial and special plans, the Civil Protection Plan of Catalonia, volunteering, and a specific levy) and coordination mechanisms with the State, local entities, and other emergency services.

1. Basic regulatory framework

At the state level, the reference is the Law 17/2015 of the National Civil Protection System, which conceives civil protection as part of public security and national security policy. This law strengthens prevention (risk maps, planning, self-protection), coordination among administrations, response to emergencies of national interest, and the restoration of normality, including the figure of the “area severely affected by a civil protection emergency.”

In Catalonia, the main regulation is the Llei 4/1997, de protecció civil de Catalunya, which fully regulates the matter in Catalonia's territory, except for emergencies declared “of national interest” by the State, which are outside its scope. This law is complemented, among others, by:

• Decret 87/2017, on the Civil Protection Commission of Catalonia.
• Decret 30/2015, on the catalog of activities and centers required to adopt self-protection measures.
• ORDRE INT/202/2017, on the actions of civil protection volunteer associations.
• Order of January 11, 1996, on the General Register of civil protection plans.
• Organizational norms of the Department of the Interior, such as Decret 41/2024 and Decret 239/2025, which affect the competent administrative structure.

2. Basic functions according to Llei 4/1997

Article 1 of Llei 4/1997 establishes that civil protection in Catalonia includes actions aimed at protecting people, property, and the environment against situations of serious collective risk, disasters, and public calamities. Article 3 specifies the purposes, which are, in practice, the main functions of Catalan civil protection:

• Risk anticipation: objective analysis of risks and their location in the territory. It is implemented through the Civil Protection Map of Catalonia (art. 12), prepared and reviewed by the Government based on studies from various administrations.
• Prevention: actions to reduce risk and detect it immediately (surveillance). The law requires urban, territorial, and sectoral regulations to consider the Map and the Risk Activities Catalog (art. 14), and the Civil Protection Commission advises on sectoral regulatory projects.
• Planning: preparation of civil protection plans establishing responses, coordination structure, communications, command, and control. The law distinguishes:
  • Civil Protection Plan of Catalonia (PROCICAT de facto): framework plan approved by the Government, integrating territorial and special plans, incorporating the resource catalog, and setting recovery protocols and guidelines (art. 16).
  • Territorial plans, including mandatory basic municipal emergency plans for certain municipalities (art. 17).
  • Special plans for specific risks (floods, seismic, chemical, hazardous goods transport, forest fires, volcanic, and others determined by the Government), declared of interest to Catalonia (art. 18).
  • Self-protection plans of centers, companies, and facilities, linked to the catalog approved by Decret 30/2015.
• Intervention: actions to eliminate causes and alleviate, correct, and minimize the effects of disasters and public calamities (art. 3.d), mobilizing intervention and assistance services integrated into the civil protection structure.
• Restoration of normality: restoring essential services and preparing recovery plans (art. 3.e), consistent with the aid and post-emergency measures framework also provided by Law 17/2015.
• Training of intervention groups and information and training of the population (arts. 3.f and g), including self-protection content.

3. Organization, coordination, and volunteering

Llei 4/1997 establishes an integrated civil protection structure involving the Generalitat, local entities, and self-protection services. It regulates the functions and competencies of each administration, assistance and support mechanisms for municipalities, and the integration of municipal plans into regional plans.

The Civil Protection Commission of Catalonia acts as a key collegiate body for planning, plan approval, and inter-administrative coordination. Volunteer associations are specifically regulated by ORDRE INT/202/2017, which defines their actions and orderly integration into the system, aligned with principles of solidarity, public responsibility, and self-protection (art. 2).

Finally, the law provides a civil protection levy on certain patrimonial elements linked to risk activities, entirely destined to finance anticipation, prevention, planning, information, and training actions, reinforcing the principle that risk generators contribute to system costs.

4. Connection with state regulations and planning

Catalonia's competencies are exercised “without prejudice” to emergencies declared of national interest by the State, according to STC 58/2017 on Law 17/2015 and constitutional doctrine on public security and civil protection. In major disasters of national interest, state direction under Law 17/2015 applies, but also using Catalan resources and organization (PROCICAT plans, regional coordination centers), which are operationally integrated into the National System.

Other state instruments related to risks in Catalonia, such as Royal Decree 688/2023 on the flood risk management plan of Catalonia's river basin, coordinate with regional planning, especially with special flood plans and territorial and municipal plans.

Overall, civil protection in Catalonia combines a basic state framework and broad regional development, with full competencies in anticipation, prevention, planning, ordinary emergency management, and recovery in its territory, coordinated with the State when the emergency exceeds the regional scope.

After a forest fire, a municipality can only access ordinary state aid if two major conditions are met: that the incident is significant enough to justify State intervention and, usually, that the territory is declared a “zone severely affected by a civil protection emergency” (the former “catastrophic zone”) according to the Law 17/2015; and that the municipality documents the damages and expenses, submits its application within the deadline, and complies with what is established by the Council of Ministers' agreement and, if applicable, the royal decree-laws and development orders.

Basic legal framework

The general regulation is in the Law 17/2015, of the National Civil Protection System, which provides:

• A common aid regime for the recovery phase after emergencies.
• The figure of the zone severely affected by a civil protection emergency, whose declaration corresponds to the Council of Ministers (arts. 23-24, according to the text reproduced in the research).
• Specific measures for local corporations: compensations for urgent actions and subsidies for damages to municipal infrastructures and provincial and island road networks.

Based on this general framework, royal decree-laws of aid are issued case by case (for example, Royal Decree-law 2/2019 and Royal Decree-law 11/2019) and sectoral regulations such as Order TES/443/2022, specific for zones declared due to forest fires and floods, or Royal Decree-law 15/2022 on forest fires.

Material requirements: type and magnitude of damage

1. Sufficient damages for the declaration of “severely affected zone”

According to Law 17/2015, for the Government to declare a zone severely affected by a civil protection emergency, it is assessed that:

• Personal or material damages have occurred from an incident that severely disrupts the living conditions of the population in a specific area, or
• Essential public services have been paralyzed (water, electricity, road access, etc.).

The law clarifies that aid is always non-indemnity in nature and that material damages must be “certain, economically assessable, and related to goods covered by insurance, public or private.”

2. Nature of subsidizable municipal expenses

In royal decree-laws such as 2/2019 and 11/2019, which develop Law 17/2015, it is specified that, for local corporations:

• Urgent action expenses to guarantee people's life and safety and the functioning of essential services (evacuations, lodging, urgent road cleaning, mud or debris removal, etc.) can be subsidized.
• Works carried out with the municipality's own ordinary means (existing machinery and personnel, firefighters, local police, civil protection) are not subsidized.
• Regarding municipal infrastructures and equipment, subsidies are foreseen, usually up to a percentage of the cost (for example, up to 50% in the scheme of Royal Decree-law 11/2019).

Formal and procedural requirements

1. Declaration by the Council of Ministers

The declaration of a severely affected zone is made by agreement of the Council of Ministers, at the proposal of the competent Ministries, and includes delimitation of the affected area. Law 17/2015 indicates that this declaration can be requested by interested public administrations (including municipalities) and that the Government may request a report from the autonomous community.

There are also recent declarative agreements published by orders such as Order PJC/1222/2024 (declaration of affected zone due to DANA, not fires, but with the same scheme) or Order INT/592/2025, which establish procedural specialities for aid to local corporations.

2. Application and documentation by municipalities

Royal decree-laws of aid usually set:

• Application deadlines: for example, two months from the entry into force of the royal decree-law or from the publication of the declaration agreement (as foreseen in Royal Decree-law 2/2019 and 11/2019 for aid to local corporations).
• Processing bodies: Government Delegations or Subdelegations, which submit proposals to the competent ministries (Interior, Territorial Policy, etc.).
• Minimum content: descriptive report of actions, detailed list of expenses and damages, municipal technical reports, and, if applicable, proof of co-financing.

Additionally, certain sectoral regulations specify specific requirements (for example, conditions to apply labor and Social Security measures in Order TES/443/2022, or in orders such as TES/1223/2021 and ISM/707/2021, issued under the same Law 17/2015).

Compatibility of aid and coordination

Law 17/2015 foresees that aid for material damages is compatible with others from different administrations or insurance indemnities, provided the total does not exceed the damage value, and that the Insurance Compensation Consortium may collaborate in damage assessment.

In practice, many aid packages —such as those in Royal Decree-law 20/2022 or fiscal and financial measures linked to 2022 fire damages regulated in resolutions like that of January 30, 2023 (compensation of tax benefits in IBI and IAE)— are structured so that the municipality coordinates its applications with those of individuals and companies, under the umbrella of the severely affected zone declaration.

Other contextual regulations, such as Law 21/2015 on Forests, the 2019 National Civil Protection Strategy and its update in Order PJC/1430/2024, or sectoral instruments like Order PCM/641/2021 on indemnities in forest fire extinction, complete the framework, but the specific requirements for a municipality to receive state aid after a forest fire always pivot on the above elements.

Finally, it should be noted that this state scheme is combined with possible own lines from autonomous communities and provincial councils, but the question you pose is framed at the state level, mainly regulated by Law 17/2015 and the cascade of royal decree-laws and orders that develop it in each specific episode.
