Construction BMPs

BMP Tip: Installations

When do I have to install temporary best management practices (BMPs) on my construction site?   Planning and proper installation of BMPs is required prior to the start of construction activity and on-going BMP implementation during construction activity is needed to minimize the pollutants from leaving a construction site in stormwater. Properly planning your construction […]

BMP Tip: Run-on Diversions

How can you best manage storm water run-on at your construction site? Are you doing ground disturbing activities and trying to manage storm water? Do you have the challenge of storm water running on to your project from another property? Should you divert the storm water around or through your project? Run-on is storm water […]

BMP Tip: Storm Water Pollution Prevention Plans

What is a Storm Water Pollution Prevention Plan (SWPPP)? Do you have a plan in place that identifies potential sources of storm water pollution on your construction project and best management practices and procedures to be implemented throughout all phases of construction to minimize the amount of pollutants in storm water? Construction sites are dynamic, […]

Construction BMP Tip: Types of Erosion

Is erosion occurring on your project? Erosion is the process by which soil particles are removed from the land surface by wind, water, or gravity. Sedimentation occurs when soil particles erode and then settle out. While natural erosion occurs at slow rates, erosion can be accelerated as a result of ground disturbing activities on construction […]

Construction BMP Tip: Material Storage

Are your construction materials properly stored on your project to minimize storm water pollution? During construction, storing various types of material is needed and proper handling is required to prevent and reduce storm water pollution. Establishing practices and procedures for handling and storing construction materials through the life of a project can minimize the potential […]

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 […]
