U FLAGGING SHALL BE PROVIDED AT THE EDGES OF ALL
w SENSITIVE AREA BUFFERS.
2. KEEP THE GROUND COVERED:
U. A. MINIMIZE THE AMOUNT OF EXISTING VEGETATION THAT YOU
FAUST DISTURB FOR CONSTRUCTION. KEEP OFF SENSITIVE AREAS
AND THEIR BUFFERS.
B. ALL DISTURBED ARM SHALL BE COVERED AND /OR MULCHED
WITHIN 12 HOURS, IF THEY ARE TO REMAIN L#MRKED FOR
Q MORE THAN 7 DAYS FROM MAY 1ST TO SEPTEMBER 30TH.
DURING THE MONTHS OF OCTOBER 1ST THROUGH APRIL 30TH,
O DISTURBED AREAS MUST BE COVERED OR MULCHED IF LEFT
O UNWORKED WITHIN 2 DAYS
C. ACCEPTED MULCH MATERIAL INCLUDES STRAW, WOOD FIBER AND
CELLULOSE.
.J
D. AREAS NOT BEING WORKED FOR 30 DAYS OR MORE SWILL BE
w VEGETATED, UNLESS THE CITY DETERMINES THAT WINTER
WEATHER MAKES VEGETATION ESTABLISHMENT INFEASIBLE. IF
THIS IS THE CASE. IT MUST STILL BE MORE PERMANENTLY
STABILZED, USING METHODS SUCH AS BONDED FIBER MATRIX

3. DUST CONTROL'
A. DUST IS TO BE CONTROLLED ON THE CONSTRUCTION SITE.
B. WATER TRUCK WILL BE USED TO CONTROL DUST ON DIRT /GRADED
AREAS ONLY.
C. NO SITE RUN OFF IS TO BE GENERATED BY OVER USE OF
WATERING.
D. CONTROLLING DUST ON PAVED ROADWAYS WILL BE DONE BY THE
USE OF A SWEEPER WITH WATER -JET SPRAYERS. NO RUN OFF
FROM SPRAYERS SHALL REACH THE CATCH BASINS.
