California Water Service is undertaking a project to improve drinking water reliability on the Palos Verdes Peninsula. Beginning in 2018, a portion of the construction will take place along the Palomino Ranchos and Botanic Garden Bridle Trails in Rolling Hills Estates. During construction, those sections will be temporarily closed to the public. Cal Water understands that this project will impact residents, equestrians, and trail users. They are working the PVP Horsemen’s Association, local equestrians, and others to minimize impacts. Cal Water’s priority is to ensure that all horses are safe during construction and will work with each horse owner in the affected areas to develop efficient boarding plans that work for them.
