Livermore's proximity to Lawrence Livermore National Laboratory and Lick Observatory supports shielded-lighting requirements under LMC Title 21 design standards.
Livermore Development Code Title 21 requires all outdoor lighting to be fully shielded (full cutoff) with light directed downward. Given the presence of LLNL and proximity to UC Lick Observatory on Mount Hamilton, Livermore adheres to Santa Clara/Alameda County dark-sky coordination. Commercial lighting must meet Title 24 Part 6 outdoor lighting power allowances and comply with Backlight-Uplight-Glare (BUG) ratings. Residential floodlights should use warm-color LEDs (≤3000K) and be motion-activated or timed to reduce skyglow.
Non-compliant lighting: code enforcement notice, retrofit required, fines up to $500 for continued violation.
