Exposed slopes

If the construction site is really "active", that is to say there is earth movement everyday and the slopes are changing every couple of days, do we need to protect them everysingle day? According to the CGP point 2.13 management practices letter D: "...stabilization measures must be initiated as soon as practicable in portions of the site where construction activities have temporarily or permanently ceased, but in no case more than 14 days after the construction activity in that portion of the site has temporarily or permanently ceased." Does this mean we can leave the slopes exposed where construction is taking place and protect them when construction has stop at a particular spot? Thank you.
