Use block and gravel type sediment barrier when curb inlet is located in gently sloping street segment, <br /> where water can pond and allow sediment to separate from runoff. <br /> 2. Barrier shall allow for overflow from severe storm event. <br /> 3. Inspect barriers and remove sediment after each storm event. Sediment and gravel must be removed <br /> from the traveled way immediately. <br /> Figure 4.15—Block and Gravel Curb Inlet Protection <br /> February 2005 Volume ll— Construction Stormwater Pollution Prevention 4-87 <br />
