Council narrows Crystal Valley Parkway speed limits after months of debate, votes 5–2
Summary
After presentations of traffic data and hours of public comment, Castle Rock council voted 5–2 to set a context-based posted speed on Crystal Valley Parkway: 40 mph for higher-speed segments and 35 mph for the stretch near schools and parks, with additional enforcement pledged by police.
Castle Rock’s Town Council voted 5–2 to adjust the posted speed limit on Crystal Valley Parkway after staff analysis and a large public comment period. Town traffic engineering recommended a “context-based” approach that would set some segments at 40 miles per hour while keeping the most sensitive stretches at 35 mph; Police Chief Cawley and traffic staff told council the corridor’s crash history does not show a sustained, speed-related problem.
Dan Seiler, the town’s traffic engineer, explained the recommendation and the data collection behind it. He said staff “did not actually see a real change in behavior” after the earlier reduction and noted that crash rates were lower than expected for the road’s traffic volume. Chief Cawley told council that enforcement targeted at extreme speeding and aggressive driving, supported by newly trained traffic officers, would accompany any speed adjustments to improve safety.
Residents who use Crystal Valley Parkway pushed back in public comment. “If you raise the speed limit to 40 miles per hour, you’re looking at speeds 45 to 50 with occasionally 55 miles per hour in a residential area,” said resident Susan McAfee, who highlighted a nearby school bus stop. Tim Durbin, another resident, described repeated incidents of drivers “flying by” and urged more consistent enforcement rather than raising posted limits.
Council members debated the relationship between posted limits and actual driver behavior. Supporters of the staff plan argued the 40-mph posting better matches observed driving speeds and reduces speed differentials that can cause crashes; opponents, including Councilmember Davis, said a lower posted limit sets a clearer legal standard and helps protect schoolchildren. The motion to adopt the staff-recommended revisions passed 5–2. Councilmembers Davis and Mayor Pro Tem Kavey voted no.
Next steps include updating signage, targeted enforcement in hot spots and monitoring crash and speed data to determine whether further changes are needed.
