What is the minimum height of an "A" earth dike?

The minimum height of an "A" earth dike is set at 18 inches according to Maryland's erosion and sediment control regulations. This height is established to ensure that the dike is effective in preventing sediment-laden water from leaving construction sites and entering nearby water bodies, which is crucial for maintaining water quality and adhering to regulatory requirements. The "A" earth dike design is intended for temporary sediment control, and its dimensions are determined to provide adequate storage of runoff, ensuring that sediment is trapped effectively.

A dike height of 18 inches strikes a balance between functionality and practicality in construction practices, making it sufficient for managing typical erosion and sediment issues that arise during land-disturbing activities. It also allows for ease of construction and maintenance, contributing to a better overall implementation of sediment control measures on sites where soil disturbance is taking place. Understanding this specification is vital for anyone involved in erosion and sediment control efforts in Maryland.
