Marin County Civic Center Roof Cleaning

Description

Overview

The purpose of this project is to address the maintenance needs of the Marin County Civic Center's liquid-applied waterproofing roof membrane. The vibrant blue roof on the Frank Lloyd Wright-designed building has been concealed by a layer of encrusted dust and dirt, giving it a pale gray color. The new membrane material of the roof, which was applied in 2020, needs a specialized cleaning process every five years. This summer, the new roof will be professionally cleaned for the first time to remove the layer of debris that has accumulated since it was installed, allowing the blue color to become visible once again.

Funding

The estimated cost of $1.5M will be funded by the County's 2024-2025 fiscal year's Capital Improvement Projects allocation.

Public impacts

None expected.
