SPA 124 Permit Decision Notice: Golden Valley County – Harms Road Culvert Replacement
Nov 6, 2024 11:27 AM
Golden Valley County proposes to replace a 1.5 ft diameter, 40-foot-long culvert along Harms Road with two 48” diameter Corrugated Metal Pipe (CMP) culverts and rip rap on the downstream side to prevent scour at the outfall. Flows in 2023 overtopped Harms Road and compromised the culvert. In addition, the current culvert is undersized and likely cannot carry streamflow at the 2.5-year flood interval in its condition without consistently overtopping the roadway. The stream is an ephemeral drainage and contains an approximate 10-20% chance of having year-round surface water each year. While streamflow is limited much of the year, there are designated wetlands in the project area. The primary goal of the Harms Road culvert replacement project is to bring the crossing up to County and MDT design standards by allowing the 10-year storm event to pass without overtopping the road. This will help mitigate future pollution in streams by not allowing washouts on frequent storm events. Golden Valley County proposes to implement the culvert replacement project fall 2024 and complete the project within one week.
