TREE REPLACEMENT OPTIONS
Replace removed trees: with trees of same species (Italian Stone Pine and Paper
Bark) or with trees that are consistent with LA County Public
Works project on Via Marina (Fern Pine or Mexican
Sycamore)

MITIGATION MEASURES During construction, the following mitigation measures shall be employed: ◦ Bio – Survey trees for nesting birds; Monitor water turbidity
during Least Tern nesting season ◦ Air Quality – Minimize NOx emissions (various measures
related to equipment engines and optimizing processes), ◦ Traffic – A Construction Traffic Management Plan and site-
specific construction worksite traffic control plans shall be prepared; These require review & approval from LA County DPW; Advance notice to any affected residents, businesses, and property owners shall be provided Pedestrian/Bicycle Access –Signage identifying alternative
pedestrian & bike access shall be provided when needed Public Transit – Coordination with transit providers is
required; Temporary bus stops within a reasonable walking distance shall be identified if needed

MITIGATION MEASURES (continued)
During Construction: ◦ Recreation – The City shall coordinate all construction scheduling
and activities with LA County DPW to eliminate or reduce construction-related impacts.
◦ Noise/Vibration – Restrictions on construction hours; Use of soundwall barriers around pits; Heavy trucks shall be limited to major arterial streets; The on-site construction supervisor shall have the responsibility and authority to receive and resolve noise complaints; The contractor shall develop and implement a project noise control plan; “Press-in” or drilling pile drivers shall be used rather than impact or vibratory pile-drivers, as feasible.
◦ Cultural/Paleo – Monitoring is required during excavation; Various measures in place if resources are discovered.
◦ Geological – To avoid/minimize subsidence, measures such as use of a watertight excavation support system to minimize groundwater pumping shall be used; Mitigation systems for methane gas are required
