Stop in for a cup of coffee

Chris, that culvert may not be out of line,10-12 foot top is a little narrow,and if the ditch is 4 feet deep,the slope will quickly take up the leftovers. Acceptable slope is 4:1. If its no cost out of pocket then embrace it.
i have to buy the materials, the permit and engineering was free. he stated a 15 inch diameter, 30 ft long. the slope thing makes sense though.
