Construction Milestones
In ProgressDust & Air Quality
✓ GoodOur PM10 air monitoring network — with over 20 devices positioned throughout the site — compares site dust readings to a background monitor each day, confirming construction activity isn't adding measurable dust to the neighborhood. Air quality data is sourced from South Coast AQMD public monitors. We track conditions throughout the day and proactively adjust our dust control measures, including water trucks and site barriers, to keep the neighborhood as clean as possible.
Water Usage
✓ ActiveNoise & Vibration
✓ CompliantConstruction noise is carefully managed and monitored throughout every workday using over 20 sound monitoring devices across the site. Our readings consistently stay well below the city-permitted limit, and we actively schedule the loudest work during midday hours to minimize impact on the neighborhood. Ground vibration levels have also remained low across all monitoring stations.

Ground Vibration
✓ CompliantThreshold Reference — Caltrans 2020, Newer Residential Structures
Single, brief ground disturbances such as the drop of a concrete mass during demolition. Each event is impulsive and dies out quickly. Occupants may feel these events; perception alone does not confirm structural damage. Per Caltrans 2020, Table 19.
Sustained vibration from equipment operating over extended periods — pneumatic hammers, vibratory compactors, heavy machinery. A lower threshold applies because repeated loading cycles present greater cumulative damage potential than a single transient event.
