D.C. Mun. Regs. tit. 21, § 542
542.1 Erosion can be further checked by the installation of gutters and downspouts which shall be accomplished at the earliest practical time.
542.2 Precautions shall be taken to dissipate the velocity of water existing from downspouts to a non-eroding velocity or provisions made to pipe directly to storm drains.
542.3 Retention of as much natural vegetation on the site as practicable is required. Removal of vegetation shall be limited to that which is necessary for construction or landscaping activities.
542.4 The vegetated areas retained may act as a filter to trap sediment and keep it on site.
542.5 In certain cases, the installation of small dikes constructed around the low lying perimeters of a job site is desirable to trap any sediment and keep it on site. These perimeter dikes act as small sediment basins and are consequently most effective only if other means or erosion control cannot be employed.
542.6 Design details of these and other control principles are embodied in Standards and Specifications for Soil Erosion and Sediment. Control in Developing Areas. Copies shall be available in the Department of Consumer and Regulatory Affairs, Environmental Control Division.
