Resident raises dust and speed concerns on 315th Street; county to study options
Summary
At a Cerro Gordo County meeting, resident Jim Wilson urged the board to address heavy traffic, dust and speeds on 315th Street near a campground; county staff and the sheriff agreed to run traffic counts, collect contractor quotes and reconvene with neighbors before taking formal action.
Jim Wilson, who lives at 21637 315th, told the Cerro Gordo County board during the public-comment period on Monday that traffic tied to a nearby campground has sharply increased vehicle counts on 315th Street and created persistent dust and safety worries.
"If the speed limit was a little lower, you know, say 35," Wilson said, urging the county to give the campground owner a local basis to ask guests to drive more slowly. He described about 90 seasonal campsites at the facility and said traffic on holiday weekends can reach "50, 60, 70 cars an hour." Wilson said private dust treatments cover only short frontage strips and that neighbors cannot reasonably pay to treat the whole 6,000-foot stretch.
Why it matters: Several residents said the combination of speed, dust and a nearby hill creates safety risks for people using the road and for residents near the entrance to the gravel pit. The discussion identifies options with different costs and trade-offs, from temporary speed controls and targeted dust treatments to more expensive surface improvements.
County staff described three near-term options the board could consider. Brandon (county road/maintenance staff) said polymer/enzyme additives for gravel roads can reduce dust but are not a substitute for full dust control; he estimated the additive might cut dust by roughly half in some conditions. He gave an estimated cost of about $80,000 to double-chip-seal the 6,000-foot stretch to Lucky's (which he said would effectively eliminate dust for 7–10 years) and said paving would approach $1 million. Lower-cost treatments and equipment/time costs for an enzyme approach were estimated in the $30,000–$50,000 range, depending on logistics.
The sheriff said his office would enforce whatever speed limit is posted and outlined the practical steps needed to change limits and to measure compliance. "We would just enforce whatever that speed would be you're marked for," the sheriff said, and urged that traffic counts be done during peak campground activity rather than off-peak periods so the study reflects event-driven peaks.
Neighbors also urged the board to include nearby River Road in any study because, they said, drivers there travel even faster and pose an immediate safety threat; one attendee warned, "they're going to kill her." Board members responded by recommending targeted follow-up: staff will obtain contractor quotes, the county will perform live traffic counts at peak times, and supervisors, staff and the sheriff will meet with neighbors in a smaller forum before any formal action on speed limits or road treatments.
What happens next: The board did not vote on speed limits or county-wide dust programs at the meeting. Staff will collect cost estimates and coordinate traffic-count dates; the board expects to reconvene with residents after that fact-finding to consider formal actions such as a speed study, SUP amendments or road-surface treatments.
