Core Viewpoint - The implementation of the "Coastal Building Retreat Line Management Regulations" in Qinhuangdao City marks a significant step towards coastal line protection and spatial governance, providing a regulatory framework for delineating retreat lines and controlling coastal development activities [1][2]. Group 1: Regulations Overview - The regulations are based on principles of ecological priority, safety protection, strict control, and ease of management, covering aspects such as the background for formulation, delineation criteria, and responsibilities of local governments [1][2]. - The coastal building retreat line is defined as a boundary to protect coastal ecosystems, resist marine disasters, and expand coastal space, with a designated "avoidance zone" where construction activities are generally prohibited or restricted [1][2]. Group 2: Implementation Mechanism - The delineation of the retreat line will follow the latest surveyed coastline and will be organized by local governments, requiring approval from the municipal government before public implementation [2]. - A "list of permitted projects + classified management" mechanism is introduced, allowing nine types of projects in the avoidance zone, including major national and provincial projects, ecological protection, and necessary infrastructure [2]. Group 3: Existing Structures and Tourist Areas - Existing legal structures within the avoidance zone can be renovated but not expanded or raised, with any necessary reconstruction needing to comply with planning requirements [2]. - Tourist areas such as beaches must have necessary service facilities set up reasonably, with strict control over construction scale and aesthetics to ensure harmony with the marine environment [2].
