protected by anchored mulch and temporary seeding. Excavations should be backfilled as soon as
possible, and appropriate surface protection and stabilization should be provided.
Permanent Site Stabilization
The last step is permanent stabilization. As mentioned earlier, this should not be delayed until the
entire development is completed. A significant reduction in erosion damage repair and re-grading costs
can be achieved if smaller areas are stabilized with permanent vegetation as soon as they are ready.
Most temporary sediment basins, dikes, sediment traps, and other earthen control structures are to
be removed, re-graded, mulched, and seeded before leaving the site. However, the RLD should consult
the plan before removing them to ensure that they are not removed until the surrounding area is stabilized
and they are no longer needed.
In some cases, sediment basins, diversions, and waterways are to remain as part of the permanent
stormwater runoff management system. In such cases, sediment basins should be cleaned out and seeded
with suitable permanent vegetation. Diversions and waterways should be checked, repaired if needed,
and left in good condition. The RLD should check on the final condition of permanent measures and
confirm that long-term maintenance of these facilities is accounted for.
When final grading is completed, all denuded areas should be stabilized with permanent
vegetation. The ESC specifications for permanent vegetative practices are provided in the Specifications
Section.
PROJECT INSPECTION BY RESPONSIBLE LAND DISTURBER
The RLD should inspect the site frequently throughout the project, with careful inspection at
installation of critical measures (e.g., sediment basins) and at the end of each phase for phased projects.
The RLD will need to coordinate to ensure that appropriate parties (job superintendent, foreman, etc.) are
available to participate in the inspection. Additionally, communication with the inspector from the
Program Authority may also be required to coordinate on site visits. The RLD should be familiar with the
plan and construction schedule ahead of time. Any required repairs or corrective actions indicated by the
RLD should be made immediately. Any plan modifications recommended by the RLD should be
discussed with the Owner and Plan-Approving Authority prior to implementation on site.
The RLD should also use a standard checklist when performing inspections. Most of the items on
that checklist refer to a specific Minimum Standard (MS). The items from the checklist are listed below:
Are there any denuded areas that require temporary or permanent stabilization? (MS-1)
Are soil stockpiles adequately stabilized with seeding and/or sediment trapping measures?
(MS-2)
Does permanent vegetation provide adequate stabilization? (MS-3)
Have sediment-trapping facilities been constructed as a first step? (MS-4)
Are perimeter sediment trapping measures in place and earthen structures seeded and mulched?
(MS-5)
