Today's news story about the mudslide on Arkansas 23 that has caused tons of silt to pour into Mountain Creek and thus to the Mulberry River is very important for understanding the reason that the Fayetteville City Council passed a stronger hillside ordinance.
Exactly the same stream-killing erosion has resulted from building roads and grading land in many parts of the city.
Powerful examples occurred in recent years as trees and vegetation were removed for the long-stalled Ruskin Heights project and a similar project southeast of the intersection of Township and North College.
A wetland area with prairie soil was dredged and filled for the Aspen Ridge project. When that project stopped, muddy fill dirt rain off the site for two years before the Hill Place project on the Aspen Ridge site was completed.
That problem hasn't completely stopped because of erosion of the steep railroad embankment that was strangely devegetated for the Aspen Ridge site and has not been stabilized yet.
Muddy silt from fill dirt along that railroad slope continues to flow to Pinnacle Prairie and World Peace Wetland Prairie.
Building on slopes has to be carefully planned with full understanding of the geography and geology of such sites.
