~jlnlication
Application No.: 7-U-81 (Mod.), Symantec, Inc., 10201 Torre Avenue.
Descri tp ion
Symantec proposes to locate an emergency generator on an existing concrete pad which is in the northeast area
of the property, 12'3" from the north property line (see attached site plan, Exhibit A). The generator would be
used for emergencies, and would be tested once every two weeks for IS minutes and every six months for two
Hours. Noise and visual impacts are the issues.
• Discussion
Noise: The enclosed acoustical report indicates that with mitigations, the noise level from the generator will
not exceed 50 dBA at the proposed adjacent apartment buildings in City Center, which is the maximum
nighttime standard. The balconies of the apartments are approximately 30 feet from the generator. Mitigation
consists of a 12 ft. noise barrier enclosure (see Exhibit B), made of overlapping redwood (Exhibit C), as well as
an exhaust reduction system.
Visual Impacts: The enclosure will be visible from the adjacent apartments. There are low shrubs currently
between the proposed generator site and the apartments. There are several trees in the area, but are widely
spaced apart. The new apartments also will have low shrubs on their south property line, which probably will
not interrupt the view behveen the apartments and the generator/enclosure. The redwood materials will give
the enclosure afence-like appearance, but the height will be imposing. A condition of approval requires an
additional new tree and replacing a dead tree to provide additional screening.
in
The Director approves the modification with the following conditions:
I . "felting shall be during daytime hours.
2. An additional tree and a replacement trce for the nearby dead tree shall be planted within 30 days
of approval.
