4 Environmental Analysis <br /> 4.1 Aesthetics <br /> 4.1.8 Cumulative Impacts <br /> There would be no impact with respect to scenic resources within a state scenic highway or scenic <br /> vistas because the Project is not visible from such scenic resources. Additionally, due to the <br /> Project location and surrounding terrain and site-specific nature in which light and glare is <br /> experienced, the Project's less-than-significant impact related to light and glare could not combine <br /> with impacts from other facilities. Therefore,the Project's impact to visual resources resulting from <br /> light and glare would not cause or contribute to a significant adverse cumulative impact. <br /> The cumulative projects described in Section 2.6 of Chapter 2, Project Description, have created or <br /> have the potential to create an industrial appearance within the Project viewshed primarily due to <br /> the PG&E Tesla substation, from which multiple lattice transmission towers of varying heights and <br /> shapes extend. These towers and their connecting lines are often visible against the sky, increasing <br /> their prominence. Wind turbines associated with the Altamont Pass Wind Resources Area are also <br /> visible on western hillsides, increasing the number of vertical intrusions above the horizon. The <br /> result has been a degradation of the largely agricultural, undeveloped landscape. When the neutral <br /> to adverse impacts expected from the Griffith Energy Storage Project are added to the impacts of <br /> these other projects, adverse cumulative impacts would increase. Mitigation measure AES-1 would <br /> be implemented to reduce Project contributions to cumulative impacts, reducing the impact to less <br /> than significant. <br /> 4.1.9 References <br /> Alameda County. 1966.
