Bear Gulch Infrastructure Improvements

Cal Water is proposing to construct infrastructure improvements in the Town of Portola Valley, Town of Woodside, and San Mateo County. The project will consist of the following:

  1. Reconstruction of the booster pumping station and associated facilities at our Station 13 property, located at the intersection of Portola Road and Westridge Drive in the Town of Portola Valley (see Exhibit A – Station Locations);
  2. The installation of approximately 2 miles of transmission pipeline in Portola Road, from Sand Hill Road to Old La Honda Road and Tadin Lane to Stonegate Road (see Exhibit B – Overall Portola Pipeline Map);
  3. The demolition of facilities and establishment of natural landscaping at Station 8, located immediately east of the intersection of Portola and Haysfield Road in the Town of Portola Valley;
  4. The abandonment of an 8″ main in the multi-use trail along the eastern shoulder of Portola Road from Montecito Road to Santa Maria Avenue;

The proposed improvements ensure that we will have a reliable supply of high-quality water to meet the community’s needs at all times. The project will not increase the capacity of the water system.

Project Planning

Cal Water has worked closely with the Town of Portola Valley to conduct an Initial Study pursuant to the California Environmental Quality Act (CEQA) to identify and mitigate any potential negative impacts as a result of the proposed project. The project has been subjected to a Conditional Use Permit and a thorough review and approval process by the Town’s Planning Commission.

Above ground improvements, particularly those at Station 13, have been designed in an effort to blend the facilities into the surroundings. For example, acoustic shelters will be installed over pumps for noise attenuation, and grapestake fencing and landscaping along the perimeter of the station are proposed to ease aesthetics. Additionally, we will work closely with our contractor to minimize any inconvenience to our neighbors. Cal Water and the Town plan to keep neighbors well informed of the project’s status prior to and during construction.

Project Schedule

Construction is planned to be completed by the end of 2016; see link below for project schedule details. Construction hours will comply with the Town’s ordinance, Monday through Friday, 8 am to 5:30 pm.

Project Necessity

At Cal Water, we are committed to providing our customers with a reliable supply of high-quality water. This project is critical because it will enable us to replace and relocate aging infrastructure, improving the reliability and efficiency of the potable water supply and by providing uninterrupted supply through critical pump stations of the Cal Water Bear Gulch District.
