Drainage System Maintenance to Reduce Flood Risk
Natural stream channels are typically large enough to contain only the most frequent flooding events. Larger storms which occur on the average of once every 2 or 5 years will most likely cause the streams to flow out of their banks. For this reason, it is critical that the stream channels be kept clear of trash and debris. Do not dump trash, leaves, branches, Christmas trees, or other yard waste into or adjacent to a stream or drainage ditch. These materials will be washed away during rain events and will most likely be deposited in front of downstream culverts or bridges. Blocked or partially blocked culverts increase the potential for property flooding and may cause water to flow across roadways endangering motorists.
Metro has regularly scheduled brush and yard waste pickup on a quarterly basis. Find out when your next neighborhood brush pick-up is scheduled.
