(A) Any area of land from which the natural vegetative cover has been either partially or wholly cleared by development activities shall be stabilized. Stabilization measures shall be initiated as soon as possible in portions of the site where construction activities have temporarily or permanently ceased. Temporary or permanent soil stabilization at the construction site (or a phase of the project) must be completed no later than 14 days after the construction activity in that portion of the site has temporarily or permanently ceased.
(B) Steep slopes shall be temporarily stabilized not later than seven days after construction activity on the slope has temporarily or permanently ceased.
(C) Permanent stabilization with perennial vegetation (using native herbaceous and woody plants where practicable) or other permanently stable, non-eroding surface shall replace any temporary measures as soon as practicable. Replanting with native woody and herbaceous vegetation must be accompanied by placement of straw mulch or its equivalent of sufficient coverage to control erosion until the plantings are established and are capable of controlling erosion.
(D) Reseeding must be done with an annual or perennial cover crop accompanied by placement of straw mulch or its equivalent of sufficient coverage to control erosion until such time as the cover crop is established over 90% of the seeded area.
(E) Every stabilized area must exhibit survival of a minimum of 70% of the cover crop throughout the year immediately following stabilization. Revegetation must be repeated in successive years until the minimum 70% survival for one year is achieved.
(F) In addition to the above requirements, a landscaping plan must be included describing the vegetative stabilization and management techniques to be used at the site after construction is completed. This plan must specify not only how the site will be stabilized after construction, but who will be responsible for the maintenance of vegetation at the site and what practices will be employed to ensure that adequate vegetative cover is permanently preserved.
