The Granada Drive Pipeline Replacement Project will install about 10,230 feet of welded steel pipe beneath Granada Drive, a neighborhood street in the Town of Corte Madera. This project replaces aging, leak-prone and seismically deficient piping - some of which was installed as early as 1956.
The project was further accelerated due to failing cast iron pipe, and to work in coordination with the Town of Corte Madera, which will conduct a road resurfacing project in the same area. New water mains will be installed on Estrada Lane, Paloma Drive, Granada Drive, El Camino Drive, Sonora Way and Vista Court. For more information, read Marin Water’s April 2023 Neighborhood Notification Letter for this project.
