Project Background

The Santa Ynez Reservoir Floating Cover Project was being constructed to comply with two United States Environmental Protection Agency water quality regulations:

In order to meet these two regulations, the LADWP did the following:

  • Switch disinfectants from chlorine to chloramines
  • Cover Santa Ynez Reservoir

Scope of Project

Major project components included:

  • Removal of inlet/outlet tower and resurfacing of reservoir asphalt liner
  • Construction of a blended green and black hypalon floating cover over the entire surface (~ 9.2 acres) of the reservoir
  • Construction of new firefighting facilities at the Pacific Palisades Reservoir which includes a cistern
  • Implementation of the Landscape Master Plan to mitigate the visual impacts of the floating cover. This includes:
    • Rockwork and Planting on Slope Repair Area
    • Reservoir Service Road Surface
    • Resurface the perimeter road surface with a darker color to visually blend with the adjacent reservoir cover and surroundings
    • Debris Retention Basin
    • Resurface with same material/color as service road
    • Helipad
    • Resurface the helipad area with colored pavement to complement the adjacent reservoir
    • Reservoir Dam Slope Treatment
    • Naturalized drifts of native grasses will be introduced to dam faces to add color and texture to these areas
    • Approach Road
    • Resurface the access road and concrete swale with a darker color to visually blend with the adjacent reservoir cover and surrounding hillside
    • Water Tank Removal and Infill Planting
