Construction Site Runoff Control
The 5 Pillars of Construction Management
In order to effectively manage construction stormwater, one must manage:
- Communication - The BEST management practice; effectiveness focused
- Work - implementation focused
- A contractor will properly manage a site if compensated appropriately and if the owner's and inspector's expectations are presented up front. Regulatory personnel should "inspect what you expect".
- Water - cause focused
- Diversions and conveyances direct runoff around and away from disturbed areas so construction site superintendents only have to manage the precipitation that falls on the site.
- Erosion - source focused
- Erosion control limits exposed soil making it less susceptible to wind or rain transport.
- Sediment - symptom focused (least effective)
- Sediment control uses BMPs designed to capture moving sediment and stop it from leaving construction sites.
The Power of Water
Doubling the velocity of water, increases:
- Its erosive energy by 4 times
- The mass of soil being transported by 32 times
- The size of the particle being carried 62 times
The sediment leaving construction sites impacts drainage systems and ultimately pollutes streams and rivers. Major impacts include:
- Addition of harmful nutrients, bacteria, heavy metals
- Decreased water clarity and available oxygen levels needed to sustain aquatic life
- Degradation of stream bank habitats and stream stability
How You Can Help
You can help protect streams and rivers by reporting erosion and sediment concerns before they become a problem for the environment.
City Inspection Form
This is the form that the City of Edmond's Water Quality Specialists use when inspecting OKR10-permitted construction sites:

Permittee Inspection Form
Construction sites greater than or equal to one acre require a OKR10 Construction General Permit from the Oklahoma Department of Environmental Quality (ODEQ) (2017 version). The permit requires inspections at least once every 14 days or within 24 hours of a 0.5'' of rainfall. If your site is covered under the OKR10, ODEQ has developed an Inspection Report Template to assist you in creating a customized inspection report specific to your project that complies with the minimum reporting requirements of OKR10 Part 4.3.13. Note that the use of this template is optional; you may use your own inspection report form provided it includes the minimum information required by OKR10 Part 4.3.13.
