environmental issues that must be analyzed in the EIR and it is attached for review. A summary
of the probable environmental effects of the project is presented in Table 2 below.

TABLE 2
ENVIRONMENTAL ANALYSIS OVERVIEW

Checklist Issue Potential Significant Impacts/Issues for Analysis
HAZARDS
Landslide and liquefaction hazards; substantial grading and alteration of
Geotechnical
topography; geotechnical survey required
Project site contains Tapia Canyon and its tributary, a major drainage course
Flood and it’s 100-year floodplain; increased erosion from vegetation removal; change
in drainage pattern
Project site within Very High Fire Hazard Severity Zone with single access point;
Fire adjacent Tesoro del Valle project may not be constructed thereby removing
planned additional access; no existing water source on site
Construction (grading) and increased traffic from development of site could
Noise
increase ambient noise levels
RESOU RCES
Construction (grading) and increased impermeable surfaces can affect surface
Water Quality
water quality
Santa Clarita Valley is an AQMD non-attainment area, construction and
Air Quality
increased traffic from development would increase air pollutant emissions
Project site is vacant open space containing vegetation, oak trees, and potential
Biota sensitive species; area provides wildlife movement corridor between Castaic
Creek and Angeles National Forest; biota survey required
Cultural Potential archaeological sensitivity; Phase I Archaeological Survey required
Mineral No impact — See Environmental Safety
Agricultural No impact
Portion of 1-5 is scenic highway from which the project site is visible;
Visual development of suburban uses on vacant open space alters visual character
and topography; new source of light and glare
SERVICES
Project exceeds County thresholds of 25 dwelling units necessary to consider
Traffic/Access traffic impacts and 50 dwelling units to consider congestion management
program (CMP) analysis; project site not near existing emergency services
Sewer Project site not currently served by sewer infrastructure
Project would generate additional school-age children; school districts serving
Education project are both currently exceeding their capacity; project site is not close to
existing schools
Fire and police protection is not readily available to project site due to location,
Fire/Sheriff
access, and undeveloped nature
Project site does not have existing water supply; limited utility infrastructure
Utility/Other
currently in place
OTHER ISSUES
General Project would alter character of site to suburban
Project contains abandoned oil wells from historical activities and one active oil
Environmental Safety
well
Land Use Project includes density control design. DMS discussion
Potential to induce population growth; project would generate the need for
Population/Recreation
additional recreational facilities
Project has the potential to significantly affect biota and water quality and is
Mandatory Findings
located in an area with fire and flood hazards
