City Council - Oct 6, 2026
The council approved a 10-year surface quarry expansion and modern operating conditions for the existing quarry that has run since 1988 with virtually no limits. Neighbors worry about silica dust, asthma and blasting; the counterargument is that without approval the quarry continues indefinitely under weaker 1988 rules. New stipulations require baseline air testing, daily street sweeping, crusher containment upgrades and public reporting.
