5.7 Biological Resources

PDF 7-8 To minimize the introduction and spread of invasive plants on the site, the
Centennial Specific Plan contains a list of invasive plant species that will be
prohibited from being planted on the site.

PDF 11-4 from Section 5.11, Air Resources, is also applicable to the analysis in this section.

5.7.5 THRESHOLD CRITERIA

California Environmental Quality Act Criteria

The following significance threshold criteria are derived from the County of Los Angeles
Environmental Checklist. The Project would have a significant impact related to biological
resources if it would:

Threshold 7-1 Have a substantial adverse effect, either directly or through habitat
modifications, on any species identified as a candidate, sensitive, or
special status species in local or regional plans, policies, or
regulations, or by the CDFW or USFWS.

Threshold 7-2 Have a substantial adverse effect on any sensitive natural
communities (e.g., riparian habitat, coastal sage scrub, oak
woodlands, non-jurisdictional wetlands) identified in local or
regional plans, policies, regulations or by CDFW or USFWS.

Threshold 7-3 Have a substantial adverse effect on federally or state protected
wetlands (including, but not limited to, marshes, vernal pools,
coastal wetlands, and drainages) or waters of the United States, as
defined by §404 of the federal Clean Water Act or California Fish
and Game code §1600 et seq. through direct removal, filling,
hydrological interruption, or other means.

Threshold 7-4 Interfere substantially with the movement of any native resident or
migratory fish or wildlife species or with established native
resident or migratory wildlife corridors, or impede the use of native
wildlife nursery sites.

Threshold 7-5 Convert oak woodlands (as defined by the state, oak woodlands are
oak stands with greater than 10 percent canopy cover with oaks at
least 5 inches in diameter measured at 4.5 feet above mean natural
grade) or otherwise contain oak or other unique native trees
(junipers, Joshuas, southern California black walnut, etc.).

Threshold 7-6 Conflict with any local policies or ordinances protecting biological
resources, including Wildflower Reserve Areas (L.A. County Code,
Title 12, Ch. 12.36), the Los Angeles County Oak Tree Ordinance
(L.A. County Code, Title 22, Ch. 22.56, Part 16), the Significant
Ecological Areas (SEAs) (L.A. County Code, Title 22, §22.56.215),
