Managing Stormwater in Sergeant Bluff

Stormwater can pose a risk to our water resources. Pollutants in stormwater can impact lakes, streams and rivers. New programs to control stormwater pollution have been adopted by our community.

What is Stormwater Runoff?
Stormwater runoff is rainfall or snowmelt that runs off impervious surfaces like roads, buildings, and compacted soils. Stormwater runoff is collected and conveyed through storm sewers directly into streams, rivers, and lakes without being treated.

The Problem
Pollutants accumulate on impervious surfaces between rainfall events.  Frequent, small rains wash pollutants into streams, rivers, and lakes. These pollutants negatively impact water quality. 

As communities grow, impervious areas increase. Greater impervious surfaces cause the volume and rate of stormwater runoff to increase. This can result in flooding, stream channel degradation, and increased water pollution in our surface waters.

Stormwater Management
The traditional approach to stormwater management focuses primarily on flood control. Today, our city is required to manage for both water quality and quantity by using practices that infiltrate more rainfall and reduce the volume of storm water runoff. 

Stormwater Regulations in Sergeant Bluff
To comply with new federal regulations, our city is required to implement a new stormwater management program. Some requirements include:

  1. Managing stormwater runoff for water quality protection
  2. Reducing sediment loss from construction sites
  3. Developing ordinances to meet program goals
  4. Inspecting storm drain outlets for unwanted discharges
  5. Providing public education and involvement

Awareness & Responsibility
Daily activities can impact water quality. Most rainfall drains untreated to streams and lakes through storm drains in neighborhoods. There are many ways you can prevent stormwater pollution:

  1. Wash your car at a carwash or on the lawn, not the driveway
  2. Re-direct roof drains to gardens or other vegetated areas
  3. Properly dispose of all hazardous household waste
  4. Minimize use of fertilizers
  5. Clean up after your pets

If you have a stormwater issue, please call the City of Sergeant Bluff on-call maintenance number at (712) 203-0206.

To report a stormwater complaint, please complete our Stormwater Pollution Prevention Report Form (fillable or non-fillable) and follow the instructions.

Protecting Iowa's Water Supply
Erosion & Sediment Control

The City has available, in the form of pamphlets, lots of information on how homeowners can educate themselves on methods that can be used to infiltrate stormwater. Most yards shed water and are unable to soak up rain due to compacted soils. When it rains in urban areas, water washes off roofs, lawns, and impervious surfaces such as sidewalks, streets and driveways and eventually makes its way to storm drains that drain to streams and lakes. Carried with that stormwater are any pollutants that it captures along the way. Installing rain gardens, improving soil quality and infiltration, planting native landscaping, etc. are all great ways to maintain water on your own property and lessen that which is carried away. Learn how to use fertilizers and which ones not to use. Learn more about rainscaping practices that capture and infiltrate stormwater. Create beautiful landscapes in your yard that sustainably manage stormwater.
