NOTES:
1. CONDITIONS OF USE
1.1. REQUIRED AT:
1.1.1. THE TOP OF ALL SLOPES IN EXCESS OF 3H:1V AND WITH MORE THAN 20 FEET OF VERTICAL RELIEF.
1.1.2. AT INTERVALS ON ANY SLOPES THAT EXCEEDS THE DIMENSIONS SPECIFIED BELOW.
2. DESIGN AND INSTALLATION SPECIFICATIONS
2A. FOR SLOPES STEEPER THAN 2H:1V WITH MORE THAN 10 FEET OF VERTICAL RELIEF, BENCHES MAY BE CONSTRUCTED OR CLOSER SPACED
INTERCEPTOR SWALES MAY BE USED. THE DESIRED MEASURE MUST BE DESIGNED BY AN ENGINEER TO EFFECTIVELY INTERCEPT THE HIGH VELOCITY
RUNOFF TO A SEDIMENT POND OR TRAP.
2.2. CONSTRUCTION TRAFFIC OVER TEMPORARY SWALES SHALL BE MINIMIZED.
3. MAINTENANCE STANDARDS
3.1. DAMAGE RESULTING FROM RUNOFF OR CONSTRUCTION ACTIVITY SHALL BE REPAIRED IMMEDIATELY.
3.2. IF THE FACILITIES DO NOT REGULARLY RETAIN STORM RUNOFF, THE CAPACITY AND/OR FREQUENCY OF THE SWALES SHALL BE INCREASED.
