Storm Control Measure Maintenance and Inspections

What is a storm control measure, and why is it important?
Storm control measure or SCM is a permanent structural device or a strategy to manage stormwater runoff, aiming to improve water quality by removing pollutants and controlling water quantity to reduce flooding and erosion. Storm control measures come in all shapes and sizes. Sometimes you may not even know that they are there. Depending on land availability, site needs, and maintenance requirements, each SCM is designed to cater to the needs of the site.

What you need to know:
Most jurisdictions require a licensed engineer to inspect and report findings annually for all storm control measures within the area. When projects are completed, maintenance agreements are put in place between the governing jurisdictions and the landowners stating that the owner understands and agrees to maintain and inspect the SCM at regular intervals. While maintenance may vary depending on the type of SCM and time of year, all measures should be inspected by an owner or representative on a monthly basis to ensure everything is working properly and no new problems arise.

Why monthly inspections are ideal:
Water will always find the path of least resistance. When erosion begins, water will continue down that path, creating a bigger problem, scouring away the earth with every storm. Catching it early will save you time and money when repairs are required.

Properly maintained SCMs look different for each type; however, ultimately, the idea is the same. Vegetation should be maintained throughout the year to ensure that unwanted growth is removed and the designed plantings remain healthy. The plants and grass you see around ponds and sand filters help to reduce the pollution in stormwater runoff, as well as limit the erosion on banks and dams. Stone ballast or sand on the filter side should be clear of vegetation and sediment buildup. This allows the water to filter through and enter the underdrain system which takes the water to the outlet structure and eventually outfalls into streams or wetlands.
