The City of Waco is seeking vendors for the Gibbon and Lemur Island erosion repair project at the Cameron Park Zoo. This involves grading, installation of gabion mattresses, and placement of grouted riprap to stabilize slopes and prevent future erosion. The project includes reshaping and grading the existing areas around both islands to create a stable foundation for the erosion control measures. Gabion mattresses will be installed on designated slopes with filter fabric underneath to prevent soil migration and ensure long-term stability. The mattresses will be constructed with stone-filled wire mesh baskets, properly anchored and aligned to withstand varying water levels while blending into the natural environment. Grouted riprap will be placed in areas requiring additional protection due to steeper slopes or high hydraulic forces, with detailed joint work to prevent water infiltration and erosion. The contractor will implement erosion control measures throughout the construction process to protect the surrounding pond ecosystem and wildlife. This includes temporary silt fencing and sediment barriers to minimize runoff. Construction is expected to be completed within 90 calendar days from the notice to proceed. All work must comply with the specified grading, materials, and installation requirements, with regular inspections to ensure adherence to the project’s standards and environmental regulations. Gabion mattresses and riprap will be integrated seamlessly into the landscape to restore the islands and enhance long-term stability while preserving the zoo pond’s aesthetic and functional aspects.
