Key Details of the California Coastal Act

Issuing Agency: California Coastal Commission

Year Established: 1976

Last Amended: 2022

Statutory Authority: The California Coastal Act of 1976

Primary Legal Reference: California Public Resources Code, Division 20, Sections 30000-30900

Overview of the California Coastal Act

The California Coastal Act is a comprehensive state law that operates within the broader framework of the federal Coastal Zone Management Act (CZMA) of 1972.1 The Coastal Act aims to protect, maintain, and, where feasible, enhance and restore the overall quality of the coastal zone environment and its natural and artificial resources.2

The primary state agency responsible for administering and enforcing the Coastal Act is the California Coastal Commission, which was established by the Act itself. The Commission works in partnership with local governments to manage the state's coastal resources.3

The Coastal Act was enacted in 1976 as a response to growing concerns about the rapid development and deterioration of California's coastal resources. It has undergone several amendments over the years, with the most recent significant changes occurring in 2022.4

The Act's general approach involves requiring local governments to prepare and implement Local Coastal Programs (LCPs) that guide development in the coastal zone. The Coastal Commission reviews and certifies these LCPs to ensure they are consistent with the policies and goals of the Coastal Act.5

The Coastal Act applies to all development activities within the state's coastal zone, which generally extends 1,000 yards inland from the mean high tide line. However, in significant coastal estuarine, habitat, and recreational areas, the coastal zone can extend inland to the first major ridgeline or up to five miles from the mean high tide line.6

What does the California Coastal Act protect?

The California Coastal Act protects a wide range of coastal resources, including:

  1. Public access to the coast and shoreline7
  2. Coastal habitats and sensitive species8
  3. Agricultural lands9
  4. Visual resources and scenic qualities of coastal areas10
  5. Coastal water quality11
  6. Archaeological and paleontological resources12

The Act protects these resources from adverse impacts caused by development, overuse, and pollution. It achieves this protection through various mechanisms, such as requiring coastal development permits for most development activities in the coastal zone, establishing marine protected areas, and mandating the preparation of LCPs that guide local land use decisions.13


Regulated Activities & Entities

The California Coastal Act, enacted in 1976, is a comprehensive legislation that regulates development activities within the state's coastal zone to protect and enhance California's coastal resources. The Act applies to a wide range of entities and activities that have the potential to impact the coastal environment, including:

  • Private individuals and businesses undertaking construction, land use changes, or resource extraction in the coastal zone
  • Local governments responsible for land use planning and permitting in coastal areas
  • State agencies involved in coastal resource management, such as the California Coastal Commission and the State Lands Commission

The California Coastal Act prohibits or restricts certain activities that may have adverse effects on coastal resources, such as:

  1. Dredging and filling of coastal waters, wetlands, and estuaries: These activities can disrupt coastal habitats and alter natural shoreline processes, and are generally prohibited unless necessary for approved coastal-dependent uses or habitat restoration projects.

  2. Shoreline armoring and alteration: The construction of seawalls, revetments, and other hard structures to protect against coastal erosion is restricted to minimize interference with natural shoreline processes and public access to the coast.

  3. Discharge of pollutants into coastal waters: The release of pollutants, including sewage, industrial waste, and stormwater runoff, is strictly regulated to protect water quality and marine life in coastal areas.

  4. Impacts to environmentally sensitive habitat areas (ESHA): Development activities that significantly disrupt or degrade areas designated as ESHA, such as wetlands, riparian habitats, and rare species habitats, are prohibited unless they are coastal-dependent and no feasible alternatives exist.

These prohibitions and restrictions are designed to safeguard the ecological integrity, natural beauty, and public accessibility of California's coastal resources for current and future generations.

Structure and Key Provisions

The California Coastal Act is organized into several chapters that cover various aspects of coastal resource management and development regulation. Some of the key sections include:

Chapter 2: Definitions (Section 30100-30122)

This chapter provides definitions for important terms used throughout the Act, such as "coastal zone," "development," and "environmentally sensitive area."

Chapter 3: Coastal Resources Planning and Management Policies (Section 30200-30265.5)

This chapter establishes the core policies that guide the protection and management of coastal resources, including:

  • Article 2: Public Access (Section 30210-30214)
  • Article 3: Recreation (Section 30220-30224)
  • Article 4: Marine Environment (Section 30230-30237)
  • Article 5: Land Resources (Section 30240-30244)
  • Article 6: Development (Section 30250-30255)

Chapter 5: State Agencies (Section 30400-30420)

This chapter outlines the roles and responsibilities of state agencies in implementing the Coastal Act, particularly the California Coastal Commission.

Chapter 7: Development Controls (Section 30600-30627)

This chapter establishes the permitting requirements for development activities in the coastal zone, including the coastal development permit process and exemptions.

It is essential for project proponents to consult the full text of the California Coastal Act and engage with the relevant agencies, such as the California Coastal Commission and local governments, to obtain project-specific guidance and ensure compliance with all applicable provisions of the Act.


Regulatory Standards & Limitations

The California Coastal Act establishes various standards and limitations to protect and preserve the state's coastal resources. These include:

  • Development Standards: The Act sets forth criteria for the siting and design of new development in the coastal zone, such as setback requirements, height limitations, and visual compatibility with the surrounding area.14
  • Resource Protection: The Act requires the protection of sensitive coastal resources, including wetlands, estuaries, and marine habitats, by limiting development in these areas and establishing buffer zones.15
  • Public Access: The Act mandates the provision of public access to the coast, including the dedication of easements and the construction of accessways, as a condition of new development.16
  • Shoreline Protection: The Act regulates the construction of shoreline protective devices, such as seawalls and revetments, to minimize adverse impacts on coastal processes and public access.17

These standards are implemented through the coastal development permit process, which is administered by the California Coastal Commission and local governments with certified Local Coastal Programs (LCPs). Enforcement is carried out through a combination of permit conditions, regular monitoring, and legal action when necessary.18

Monitoring, Reporting & Recordkeeping Obligations

The California Coastal Act imposes various monitoring, reporting, and recordkeeping requirements on regulated entities to ensure compliance with permit conditions and coastal resource protection standards. These may include:19

  • Monitoring: Permittees may be required to conduct regular monitoring of environmental conditions, such as water quality or habitat health, and submit reports to the relevant agencies.
  • Reporting: Developers may need to provide periodic reports on the status of their projects, including information on construction progress, compliance with permit conditions, and any unanticipated impacts.
  • Recordkeeping: Regulated entities must maintain accurate records of their activities, such as construction plans, monitoring data, and mitigation measures, and make these records available to the agencies upon request.

Developers and consultants should work closely with the California Coastal Commission and local governments to understand and fulfill the specific monitoring, reporting, and recordkeeping obligations that apply to their projects.20 These requirements may vary depending on the nature and location of the project, as well as the specific permit conditions imposed.

Enforcement Actions & Penalties

The California Coastal Act provides for a range of enforcement actions and penalties to address violations of the Act's provisions or permit conditions. These may include:21

  • Notices of Violation: The Coastal Commission or local government may issue a notice of violation to a permittee or property owner, requiring them to correct the violation within a specified timeframe.
  • Cease and Desist Orders: The Commission may issue a cease and desist order to stop unauthorized development or other activities that violate the Act or a permit.
  • Civil Penalties: The Act authorizes the imposition of civil penalties of up to $30,000 per violation, depending on the severity and duration of the violation.22
  • Criminal Penalties: In some cases, violations of the Act may be prosecuted as misdemeanors, with potential fines and imprisonment.23

To avoid enforcement actions and penalties, developers and consultants should prioritize proactive compliance with the Act's requirements and engage early and often with the relevant agencies. It is essential to consult the full text of the California Coastal Act and work closely with the Coastal Commission and local governments to understand the specific enforcement provisions and penalty structures that may apply to a given project.24


Recent Developments & Regulatory Outlook

In recent years, the California Coastal Act has undergone several significant developments that have shaped the current regulatory landscape. One notable change was the passage of Assembly Bill 1129 in 2019, which amended the Coastal Act to enhance the California Coastal Commission's ability to enforce public access provisions and impose penalties for violations 25. This amendment has strengthened the Commission's authority and has led to increased enforcement actions against property owners who fail to provide required public access to coastal areas.

Another important development was the California Supreme Court's decision in the case of Lynch v. California Coastal Commission in 2017 26. The court ruled that the Coastal Commission has broad authority to impose conditions on coastal development permits to protect public access and coastal resources, even if those conditions are not directly related to the specific development project. This decision has affirmed the Commission's power to regulate coastal development and has set a precedent for future permit decisions.

Looking ahead, there are several proposed amendments and policy changes that could affect the implementation of the California Coastal Act. One notable proposal is Senate Bill 1090, introduced in 2020, which aims to streamline the permitting process for certain types of coastal restoration and adaptation projects 27. If passed, this bill could make it easier for developers and environmental consultants to obtain permits for projects that enhance coastal resilience and address the impacts of climate change.

Stakeholders can stay informed about these developments by monitoring the California Coastal Commission's website, which provides regular updates on proposed regulations, pending legislation. Additionally, industry associations such as the California Association of Environmental Professionals (AEP) often provide informational resources and training opportunities related to coastal regulation.
