(Water Protection Ordinance section 17- 207B) ALL DENUDED AREAS WHICH WILL BE LEFT DORMANT FOR EXTENDED PERIODS OF TIME SHALL BE SEEDED WIN FAST GERMINATING TEMPORARY VEGETATION IMMEDIATELY FOLLOWING GRADING. SELECTION OF THE SEED MIXTURE WILL DEPEND ON THE TIME OF YEAR AND WILL BE APPLIED TO DISTURBED AIRES THAT WILL NOT BE BROUGHT TO FINAL GRADE WITHIN 30 DAYS. PLANTS SHOULD BE SELECTED APPROPRIATE TO THE SEASON AND SITE CONDITIONS FROM TABLES 3.31B AND 3.31C. NOTE THAT TABLE 3.31B PRESENTS PLANTS WHICH CAN BE USED WITHOUT EXTENSIVE EVALUAT70N OF SITE CONDITIONS, • TABLE 331C PRESENTS MORE IN-DEPTH INFORMATION ON THE PLANT MATERIALS. TO CONTROL EROSION ON BARE SOIL SURFACES, PLANTS MUST BE ABLE TO GERMINATE AND GROW. SEEDBED PREPARAT70N IS ESSENTIAL. AN EVALUAT70N SHOULD BE CONDUCTED TO DETERMINE IF LIME IS NECESSARY FOR TEMPORARY SEEDING. TABLE 331A MAY BE USED TO DETERMINE HE ACTUAL NEED ALONG WITH SUGGESTED APPLICATION RA TES: FERTILIZER SHALL BE APPLIED AS 600 LBS/ACRE OF 10-20-10 (14 LBS/1,000 SQ. FT.) OR EQUIVALENT NUTRIENTS.
