Summary

Union City bans discharging even legal "safe and sane" fireworks anywhere east of Mission Boulevard, citing dry summer vegetation, wood-frame homes, wood shake roofs, and limited evacuation routes in that hillside area.

Any area east of Mission Boulevard. This prohibition is justified by virtue of the higher fire danger in this area because the area: (a) has impacted ingress and egress due to dead end streets and limited entry/exit routes; (b) contains significant amounts of dry vegetation during the summer months when fireworks use is prevalent; (c) has mostly wood frame structures, in close proximity to each other; (d) contains slopes which make it difficult to do complete weed abatement; (e) contains structures intertwined with hazardous wild land areas; (f) contains many wood shake roofs (with high fire danger) in the residential areas.

7. Dates and Hours of Use. It is unlawful for any person to use, discharge, or explode safe and sane fireworks except during the hours of eight a.m. to ten p.m. on the days during which such Safe and Sane Fireworks may be sold pursuant to applicable regulations.

C. Parks Closures on the Fourth of July. All City parks shall close at seven-thirty p.m. on the Fourth of July, except for City sponsored public fireworks displays. (Ord. 890-21 § 2, 2021)

Full Breakdown

Section 7.26.060(B)(6) singles out the area east of Mission Boulevard for a total fireworks ban, listing dead-end streets that limit ingress/egress, dry vegetation, closely spaced wood-frame structures, slopes that hamper weed abatement, terrain intertwined with wildland, and wood shake roofs as the reasons. That geography largely overlaps the Hillside Combining District (Chapter 18.96), which separately requires development review to consider wildfire access hazards in the same hillside area.

Violations & Fines

Discharging any fireworks, including otherwise-legal safe and sane fireworks, east of Mission Boulevard is a misdemeanor under Chapter 7.26, fined up to $1,000 per violation.
