Dublin San Roman Services District releases project update

Published by

Dublin San Ramon Services District (DSRSD) has completed an Initial Study/Mitigated Negative Declaration for the proposed Tassajara Hills Pipeline Project in accordance with the California Environmental Quality Act.

The Tassajara Hills Pipeline Project would extend from an unpaved extension of Cydonia Court to an existing pipeline within Delamar Drive in Dublin, Alameda County, California, US. The proposed pipeline alignment would be located on two parcels (Assessor Parcel Number [APN] 985-0028-003-02 and 985-127-002-00).

DSRSD proposes to install approximately 1110 linear ft of 8-in. diameter high-density polyethylene (HDPE) pipeline to connect an existing 10-in. diameter pipeline within an unpaved extension of Cydonia Court with an existing 8-in. diameter pipeline within Delamar Drive in the Tassajara Hills Development in the City of Dublin. Approximately 800 ft of the proposed pipeline would be installed using horizontal directional drilling (HDD), whereby a tunnel is drilled under the ground surface and the pipeline is then pulled through the underground tunnel. The remaining 300 linear ft of pipeline would be installed using standard open trench construction within existing graded areas associated with adjacent residential development. The proposed pipeline would provide a redundant potable water supply to the Tassajara Hills Development.

The Initial Study prepared by DSRSD was undertaken for the purpose of deciding whether the proposed project may have a significant effect on the environment. On the basis of the Initial Study, DSRSD staff has concluded that the proposed project will not have a significant effect on the environment and, therefore, has prepared a Mitigated Negative Declaration. The project site is not on a list of hazardous waste sites compiled pursuant to Government Code Section 65962.5.
