  • Project Title: The Environment Construction Project for Kunshen Seawall of Tainan City.
  • Execution Agency: Sixth River Management Branch, WRA
  • 23rd Public Construction Golden Quality Awards - The Excellence Award 
  • Performance:
    "Kunshen," a term originally denoting sandbars encircling a lagoon or inland sea, stands as one of the most distinctive place names in Taiwan. "Kun" was inspired by the name of a legendary enormous fish, while "Shen" referred to the hump rising from its back. Thus, "Kunshen" translates to the back of a great fish.
    The Kunshen coastline extends for miles, featuring a soft sandy beach and offering magnificent views. Each evening, the sunset transforms the sea from a breathtaking blue to a dazzling golden, complemented by silver-white waves.
    The coastal levee is meticulously constructed with a multi-layered design and enhanced greening efforts, creating a more environmentally friendly ecosystem and a "breathing" coastal area for residents or visitors to enjoy seaside recreations.
    To rejuvenate the old seawall, a diverse range of over 30 coastal plants, including the tamanu, palaquium formosanum, and Chinaberry, have been planted. This initiative, aligned with the policy of ensuring the protective function of sea dikes and zero carbon emissions, results in a green-ecology seawall, departing from the traditional model of bare-sided seawalls.
    Two rest platforms have been established, offering excellent vantage points for observing the expansive sky and sea. Additionally, a storage pond on the forest trail behind the seawall captures surface runoff during rainy periods, facilitating water recycling while enhancing the overall environment and fostering a more sustainable and friendly ecosystem.
