Construction BMPs

Construction BMP Tip: Mulching

Do you have exposed soils on your construction project that need to be protected from water and wind erosion? During construction, ground disturbing activities often result in areas of exposed soils susceptible to erosion. If a prolonged period of time is expected where construction activity will cease or construction activities are complete, stabilizing disturbed areas […]

Construction BMP Tip: Check Dams

How can you slow down water and prevent erosion or scour in a channel or ditch on your project? Implementing effective best management practices (BMPs) to reduce the velocity of water in channels and ditches should be considered during construction activities to reduce the potential for erosion and scour which can result in polluted discharges. […]

Construction BMP Tip: Dust Control

Do you have open disturbed areas or unprotected stockpiles on your construction project? Do you have unpaved construction roads where trucks and equipment potentially generate dusty conditions? If so, you probably need to think about implementing dust control measures. The purpose of dust control on construction projects is to minimize erosion due to wind and […]

Construction BMP Tip: Concrete Washout

Will you be working with concrete on your project? Do you have a designated area for concrete washout water? Implementing proper best management practices (BMPs) to contain concrete washout water during construction activities should be considered to prevent it from discharging to a drainage system or receiving water body. Managing concrete waste and washout water […]

Construction BMPs: Soil Roughening

Why is soil roughening important on construction sites? Preventing erosion, capturing sediment, and establishing vegetation on construction projects are all practices that should be implemented during soil disturbing activities. Soil roughening is a best management practice (BMP) to prepare surface soils for the implementation of additional BMPs, prevent erosion and sedimentation, and establish vegetation. Roughening […]

Construction BMPs: Construction Entrance/Exit Stabilization

Is your construction entrance/exit stabilized? Tracking sediment from construction sites onto roadways can cause storm water pollution, as well as safety hazards. Proper planning is required to ensure adequate best management practices (BMPs) are installed to prevent off-site tracking of sediment or other pollutants by vehicles exiting construction sites. When choosing the type of BMPs […]

Construction BMPs for Protecting Stockpiles

Is your stockpile protected? Stockpiling material on construction sites is almost always needed at some point during the life of a project, so proper planning is needed to ensure that adequate best management practices (BMPs) are in place to prevent stockpiled material from polluting storm water. BMPs for protecting stockpiles include adequate cover or temporary […]

How to select perimeter controls for your next construction project

Perimeter controls on construction projects are a temporary best management practice (BMP) for sediment control. Used along the site perimeter, around temporary stockpiles, at the toe of a slope and downslope of exposed areas, perimeter controls keep sediment and potential pollutants contained, preventing them from entering our storm drains and negatively affecting Hawaii’s streams and […]

Inlet Protection - Construction BMP

Construction BMPs: Inlet Protection

Inlet protection on construction projects is a temporary best management practice (BMP) used to prevent sediment, trash and debris from entering storm drains. If you’re wondering what kind of inlet protection you need for your project, you’ll first need to consider a number of important factors and then select the option best suited for your […]

Fun With Construction BMP Terms: Erosion Control vs. Sediment Control!

Erosion and sediment control (E&SC) is a term that most of us in the construction industry are familiar with in regards to storm water runoff issues at a project’s site. But have you ever really thought about what it actually means? If you break it down and separate the words “erosion control” and “sediment control,” […]
