Medium Density Residential (4 to 8 dwellings/acre) | 0.4 |
Low Density Residential (<4 dwellings/acre) | 0.3 |

Where land use will be mixed, the runoff coefficient should be calculated using a weighted average. For example, if sixty percent (60%) of the contributing drainage area to the storm water treatment structure is Low Density Residential, thirty percent (30%) is High Density Residential, and ten percent (10%) is Open Space, the runoff coefficient is calculated as follows (0.6)(0.3)+(0.3)(0.5)+(0.1)(0.2) = (0.35) | |

* Size to pass a hydrograph with a volume equal to the WQv, a duration of two (2) hours, and peak rainfall intensity of one (1) inch/hour at a depth of no more than three (3) inches. The use of this criterion is limited to sites where the total area disturbed is five (5) acres or less. **Provide both a permanent pool and an extended detention volume above the permanent pool, each sized with at least 0.75*WQV . |
If the Percentage of Increase in Volume of Runoff is: | The Critical Storm will be: | |

50 | 100 | 10 year |
100 | 250 | 25 year |
250 | 500 | 50 year |
500 | --- | 100 year |
For example, if the percent increase between the pre- and post-development runoff volume for a one (1) year storm is thirty-five percent (35%), the Critical Storm is a five (5) year storm. The peak discharge rate of runoff for all storms up to this frequency shall be controlled so as not to exceed the peak discharge rate from the one (1) year frequency storm under pre-development conditions in the development drainage area. The post- development runoff from all less frequent storms need only be controlled to meet pre-development peak discharge rates for each of those same storms. | ||
Area requiring stabilization | Time frame to apply erosion controls |
Any disturbed area within 50 feet of a surface water of the state and not at final grade. | Within 2 days of the most recent disturbance if that area will remain idle for more than 14 days |
For all construction activities, any disturbed area, including soil stockpiles, that will be dormant for more than 14 days but less than one year, and not within 50 feet of a stream. | Within 7 days of the most recent disturbance within the area |
Disturbed areas that will be idle over winter | Prior to November 1 |
Areas at final grade | Within 7 days of reaching final grade or within 2 days of reaching final grade for areas within 50 feet of a surface water of the state |
Note: Where vegetative stabilization techniques may cause structural instability or are otherwise unobtainable, alternative stabilization techniques must be employed. These techniques may include mulching or erosion matting. | |
