HAZARDS - 1. Geotechnical

SETTING/IMPACTS

Yes No Maybe
Is the project located in an active or potentially active fault zone,
a.
Seismic Hazards Zone, or Alquist-Priolo Earthquake Fault Zone?
Landslides and liquefaction (per Seismic Hazard Zones Map Newhall

Quad.)
b. Is the project site located in an area containing a major landslide(s)?
Earthquake induced landslides (per Seismic Hazard Zones Map
Newhall Quad.)
c. Is the project site located in an area having high slope instability?
Pending on the result of geotechnical study
Is the project site subject to high subsidence, high groundwater level,
d.
liquefaction, or hydrocompaction?
Liquefaction (per Seismic Hazard Zones Map Newhall Quad.)
Is the proposed project considered a sensitive use (school, hospital,
e. public assembly site) located in close proximity to a significant
geotechnical hazard?

Will the project entail substantial grading and/or alteration of
f.
topography including slopes of over 25%?
6.9 million cubic yards of grading within the development envelope;
grading will be balanced on-site, in addition to offsite roadway/bridge
improvements.
Would the project be located on expansive soil, as defined in Table
g. 18-1-B of Uniform Building Code (1994), creating substantial risks to
life or property?
Pending on the result of geotechnical survey
h. Other factors?

STANDARD CODE REQUIREMENTS

Building Ordinance No. 2225 – Sections 308B, 309, 310, and 311 and Chapters 29 and 70

MITIGATION MEASURES / OTHER CONSIDERATIONS

Lot Size Project Design Approval of Geotechnical Report by DPW

CONCLUSION

Considering the above information, could the project have a significant impact (individually or
cumulatively) on, or be impacted by, geotechnical factors?

Potentially significant Less than significant with project mitigation Less than significant/No Impact
