Key Points Discussed Timestamps & Key Topics

[00:04:00] – NRCS Project: Riverbank Armoring Without Riprap

• Eroding farmland and an at-risk road along the West Fork of the Des Moines River

• Used Tesco units filled with native soil and armored with ArmorMax

• Entire project required zero imported aggregate

“This entire couple thousand feet of riverbank required exactly zero aggregate.” – Kevin Good

[00:14:00] – Extreme Rainfall: Highway Armoring with Flexamat

• Interstate 680 (Iowa) vulnerable to Missouri River overtopping

• 3 miles of Flexamat installed to prevent scour and failure

• Fast response using asphalt and soil over tied concrete mats

“We didn’t even get the mat all the way in before the water came again.” – Kevin Good

[00:25:00] – Bridge Scour Protection: 2-Ton Rock Bags

• Wisconsin DOT bridge on Lake Superior had up to 14 feet of scour

• Installed 100+ two-ton rock bags using a rowboat and crane

• Allowed sediment to filter in and stabilize the footings

“You can’t use geotextile in the middle of a stream—but you can use these.” – Kevin Good

[00:34:00] – Aging Infrastructure: Concrete Canvas in Culverts

• Henry County’s 84" culvert had rusted out at the invert

• Installed concrete canvas lining in one day

• Local crews saved over $110,000 vs. full replacement

“If you catch it early, you can fix a culvert for a tenth of the price.” – Kevin Good

[00:41:00] – Irrigation Canal Lining with Concrete Canvas

• Twin Loops Irrigation District in Nebraska

• Used 6-foot-wide rolls to reline cracked concrete canals

• Installed in rainy conditions with minimal crew

“We rolled out new material and gave this canal another 100 years.” – Kevin Good

[00:47:00] – Stormwater Inlet Protection: A Source Control Case Study

• Des Moines neighborhood tracked sediment from just two inlets

• Over 200 lbs of dried sediment collected in one year

• Led to public education campaign for homeowners

“One month the fire department had to respond—the storm sewer was on fire from dried sediment and hydraulic fluid.” – Kevin Good
