Dredging of March 29 Park Lake Progresses Under Strict Environmental Controls

Introduction

As part of a comprehensive urban renewal strategy, Da Nang has initiated an extensive upgrade of March 29 Park Lake. The core of this initiative is the implementation of precise environmental controls throughout the dredging phase, ensuring that the project supports both flood mitigation and ecological safety. The dredging operation, scheduled from mid-April to mid-August 2025, is being conducted with a focus on minimizing environmental impact and preparing the area before the storm season begins.

1. Project Background and Objectives

The renovation of March 29 Park Lake is a central feature of Da Nang’s infrastructure improvement efforts, backed by a 673 billion VND investment. Spanning nearly 19 hectares, the project aims to enhance both utility and aesthetic value. With environmental controls embedded into the design and construction process, the goal is to transform the lake into a flood-control asset and a vibrant public space.

A defining feature of the renovation is the architectural vision known as the “Peace Ring,” which will add modern amenities around the lake such as boat docks, fountains, open-air gyms, and performance stages. These upgrades will make March 29 Park Lake not only more resilient but also more accessible and enjoyable for local communities.

2. Technical Details of the Dredging Work

Dredging at March 29 Park Lake is being carried out across four defined zones, totaling an estimated 107,795 m³ of sediment:

• Zone 1: 2.53 hectares, 27,651 m³
  
• Zone 2: 2.39 hectares, 24,181 m³
  
• Zone 3: 3.48 hectares, 36,914 m³
  
• Zone 4: 1.83 hectares, 19,049 m³
  

To facilitate safe sediment removal, the water level in March 29 Park Lake is lowered by diverting it through an underground sewer along Le Do Street. Throughout the process, contractors have integrated environmental controls such as staged dewatering, isolation of dredging zones, and continuous monitoring to ensure minimal disruption to the ecosystem.

3. Environmental Control Measures During Dredging

Environmental controls are at the heart of the dredging strategy for March 29 Park Lake. Before any sediment removal begins, the lake’s aquatic life is safeguarded by mesh barriers that isolate fish from active construction zones. Water is then pumped out, and the exposed mud is treated with deodorizing sprays to prevent unpleasant odors from affecting surrounding neighborhoods.

The mud is allowed to dry on-site to a safe viscosity of below 0.75, ensuring that it can be safely handled and transported. These environmental controls are not only preventive but also proactive, ensuring that every step of the dredging process aligns with health, safety, and ecological standards.

4. Dredged Material Management and Transport

The transport of dredged materials from March 29 Park Lake is governed by detailed environmental controls to minimize road pollution, manage traffic, and ensure compliance with city ordinances. Dried mud is excavated and transferred to two approved dumping sites:

• Hoa Ninh Quarry: Capacity 94,253 m³, Distance 17.9 km
  
• Group 69 Quarry: Capacity 15,000 m³, Distance 7.7 km
  

Each day, approximately 2,150 m³ of material is transported in up to 307 round trips using 40 vehicles. To uphold environmental controls during transport, all trucks are fitted with sealed containers and covered tarps to prevent material spillage. The operation is strictly timed to avoid peak traffic hours and reduce community disturbance.

5. Infrastructure and Monitoring Protocols

To maintain strict environmental controls at March 29 Park Lake, contractors have deployed a series of technological and logistical safeguards. A vehicle wash station is set up at the construction entrance to clean mud and debris off transport vehicles before they access public roads. This ensures that no sediment is spread into urban streets.

Every truck is fitted with a dash cam, and quarry entrances are monitored with surveillance cameras. These controls serve a dual purpose: reinforcing safety compliance and maintaining transparency in dredging-related activities throughout the duration of the project.

6. Community Coordination and Oversight

March 29 Park Lake’s redevelopment, particularly its dredging phase, is supported by coordinated efforts between the city’s project management board and various municipal departments. This cooperation ensures that environmental controls are not only implemented effectively but also supervised and improved as needed.

Authorities oversee everything from traffic flow during material transport to sanitation and public order. Local residents benefit from this oversight, as it guarantees that operations are conducted responsibly and in alignment with the city’s broader sustainability goals.

7. Architectural Vision: Beyond Dredging

Beyond its utility in flood mitigation, March 29 Park Lake is poised to become a civic centerpiece. The “Peace Ring” design concept includes modern, accessible infrastructure such as outdoor stages, water features, fitness areas, and family-friendly recreational spaces.

All of these enhancements are built around a framework of environmental controls, ensuring that the beauty and function of March 29 Park Lake are maintained for generations to come. The dredging work is just the beginning of a transformation that balances development with ecological stewardship.

Conclusion

The ongoing dredging of March 29 Park Lake is a model for how cities can integrate infrastructure upgrades with rigorous environmental controls. With completion of the dredging phase targeted for August 2025, the project not only reduces flood risk but also lays the foundation for a sustainable and vibrant public space.

Through careful sediment management, monitored transport operations, and coordinated city oversight, March 29 Park Lake is being renewed in a way that respects both the environment and the community. As Da Nang continues to modernize, this project stands as a blueprint for environmentally conscious urban development.
