|---|---|
Type of Operation or Character of Noise | Correction in Decibels |
Noise source operates less than 20 percent of any one hour period | Plus 5* |
Noise source operates less than five percent of any one hour period | Plus 10* |
Noise source operates less than one percent of any one hour period | Plus 15* |
Noise of impulsive character (hammering, etc.) | Minus 5 |
Noise of periodic character (hum, screech, etc.) | Minus 5 |
*Apply one of these corrections only. |
Classification | Maximum Amount of Impervious Surfaces Allowed (percent) |
|---|---|
1. Low Hazard Areas. In low hazard areas, the maximum amount of impervious surface allowed on each lot is 30 percent. Low hazard areas are defined as lands where the following conditions exist: | |
a. Slopes 15 percent to 25 percent together with class 3 seismic hazard and class 2 erosion hazard area; or | 30 |
b. Slopes 15 percent to 25 percent together with class 2 slide and slippage and class 3 erosion hazard area; or | 30 |
c. Slopes 15 percent to 25 percent together with class 2 seismic and class 3 erosion hazard area; or | 30 |
d. Seventy-five to 150 feet from the top of a ravine in which a major or minor stream passes through; or | 30 |
e. Thirty to 50 feet from the ordinary high-water mark of a lake. | 30 |
2. Moderate Hazard Areas. In moderate hazard areas, the maximum amount of impervious surface allowed on each lot is 10 percent. Moderate hazard areas are defined as those lands where the following conditions exist: zero to 30 feet from the ordinary high water mark of a lake. | 10 |
3. High Hazard Areas. In high hazard areas, the maximum impervious surface allowed on each lot is two percent. High hazard areas are defined as those lands where the following conditions exist: | |
a. Slopes 15 percent to 25 percent together with class 2 slide and slippage and class 3 seismic hazard, and class 3 erosion hazard area; or | 2 |
b. Slopes 15 percent to 25 percent together with class 3 slide and slippage and class 3 erosion hazard area; or | 2 |
c. Slopes 25 percent to 40 percent together with class 3 seismic and class 3 erosion hazard area; or | 2 |
d. Slopes 25 percent to 40 percent together with class 3 erosion hazard area. | 2 |
4. Severe Hazard Areas. In severe hazard areas, the maximum amount of impervious surface allowed on each lot is zero percent. Severe hazard areas are defined as those lands where the following conditions exist: | |
a. Slopes 40 percent and over; or | 0 |
b. Slopes 25 percent to 40 percent together with class 3 slide and slippage, class 3 seismic hazard, and class 3 erosion hazard area; or | 0 |
c. All ravines; or | 0 |
d. Seventy-five-foot setback from the top of any ravine. The top of a ravine is where the slope is generally less than 15 percent; or | 0 |
e. Fifty-foot setback from the ordinary high-water mark of any major creek; or | 0 |
f. Twenty-five-foot setback from the ordinary high-water mark of any minor creek; or | 0 |
g. Ten-foot setback from the top of any drainage ditch; or | 0 |
h. All wetlands as defined in the wetlands ordinance. | 0 |
