The following are the most current Guidelines for Soil Erosion and Sediment
Control :
1. One complete set of plans, and five (5) copies of plan entitled Soil Erosion
& Sediment Control.
2. Soil Erosion & Sediment Control Title.
3. Existing and Proposed Contours at 2 foot intervals. They must be legible and
consistently labeled.
4. Stabilized Construction Entrance, delineated on the plan, with supportive
detail & narrative indicating maintenance.
5. Dust Control. Methods of controlling dust and soil blowing must be included
as part of the plan.
6. Temporary and Permanent Seeding specifications, including lime, fertilizer,
seed, mulching material, types and rates of application.
7. North arrow.
8. Soil information and identification of site soil types.
9. Location of present and proposed drains and culverts with their discharge
capacities, velocities, and supporting calculations in accordance with the New
Jersey Standards for Soil Erosion & Sediment Control.
10. Delineation of any areas subject to flooding from the 100 year storm must be
delineated and included as part of the submission.
11. Delineation of Wetlands (NJSA 13:B-1, et seq.). If not applicable, state
that fact on the plan.
12. All areas subject to stream encroachment regulations must be delineated on
the plan. If not applicable, state fact on plan.
13. Engineer's signature and seal.
14. Delineation of the limit of disturbance for construction activities,
including any proposed off site disturbance.
15. Sequence of development, including the installation and maintenance of site
specific erosion control practices, and the estimated duration of each activity
for each phase of construction. Note that stormwater basins must be constructed
and stabilized during the early stages of development.
19. Location and accurate delineation of all streams, channels, water bodies,
and other natural features within and adjacent to the project area.
20. Plan delineation and supporting documentation for all structural soil
erosion methods including calculations, site-specific cross sections and
profiles of each structure.
21. Permanent vegetative seeding specification must be site specific and
appropriate to the intended usage. The Cumberland-Salem District requires that
the rate of application be a minimum of 4.0 pounds total seed per 1000 square
feet, this is equivalent to a rate of 175 total pounds of seed per acre. If
hydroseeding will be the method of application, the seed rate should be
increased by 25%. Hydroseeded areas must still receive straw mulch and tack.
22. A stormwater drainage plan, with the areas delineated on the plan that
correspond with the drainage calculations. Use arrows to indicate the direction
of flow.
23. All supporting hydrologic calculations and hydraulic design. Pipe flow
network analysis. Conduit outlet protection, 25 year design storm. Grassed
waterway, 10 year design storm. Stormwater basins, 2 & 10 year design storm,
routing through the basin with stage-storage-discharge data. Documentation that
basins will dewater within 10 days.
24. Submit a typical lot plan, noting grading, stone tire cleaning driveway,
silt fence, drainage swales, soil stockpiles, and all other appropriate erosion
control measures.
25. Plan delineation and supportive details of the following soil erosion
structures and measures:
[ ] Inlet protection [ ] Silt fence
[ ] Construction entrance [ ] Diversions
[ ] Conduit outlet protection [ ] Dewatering filters
[ ] Berms with stone wicks [ ] Slope protection structure.
26. Please provide a copy of the Pinelands Commission Certificate of Filing.
27. Stormwater management basin emergency spillway structure designs should
include permanent structural armament, such as rock rip rap, concrete or
synthetic erosion control matting.
28. If there are any off-site improvements being planned for this project,
please specify the improvements and delineate the improvements on the soil
erosion and sediment control plan.
29. Mulching specification: Salt hay or small grain straw applied at a rate of
70 to 90 lbs.11000 sq. ft. to be applied according to the New Jersey Standards.
Mulch shall be secured by approved methods, (liquid mulch binder, crimping, peg
& twine).
30. For large projects, (soil disturbance in excess of 15 acres), thought and
consideration for erosion control that would limit the overall amount of land
disturbed concurrently.
31. For a residential or commercial development, after curbs and utilities are
installed, either a vegetative filter strip or curbside sediment barriers should
be established. This feature should be detailed, delineated, and specified on
the plan.
32. Completion of the Detention Basin Data Base Summary Form if the development
proposes a stormwater management basin. The analysis should include delineation
of the watersheds) that drain to each basin on a copy of the U.S.G.S. Quad map.
33. At a minimum, silt fence should be reinforced by means of either wooden snow
fence with steel pickets or welded wire fence, minimum 14 gauge, with
rectangular openings no larger than 6" x11", supported by steel pickets.
34. Box and stone collar inlet protection should be utilized at all critical low
points. Silt sacks may be used as an acceptable substitute.
35. A pre-developed topographic drainage area map, scale appropriate to the
scope of the project, clearly showing flow paths, times of concentration,
subarea analyses which contribute discharge to the point of interest, and
identification of drainage areas with the corresponding calculations package.
36. A post developed topographic drainage area map, scale appropriate to the
scope of the project. The schematic should clearly identify the cumulative
subareas connected to the basin or point(s) of site discharge. The
identification and analysis must provide delineation of the flow paths, times of
concentration, and amounts of pervious & impervious areas connected to the
basin/point of discharge, as separate entities.
37. If the disturbed area will be 1 acres or more, the following requirement
must be addressed; The proposed soil disturbing activity for this site is in
excess of the minimum threshold set forth by the Statewide Stormwater Permitting
Program. Therefore, a Request for General Permit Authorization (R.F.A.) for
Stormwater Discharge Associated with Construction Activity is required.
38. Section 4.7 of the Standards states that "Where infiltration basins are
proposed, the existence of a stable condition at the emergency discharge area
must be provided, and for offsite stability analysis it must be assumed that
infiltration will not reduce the peak runoff for a 10 year storm." In order to
accomplish this, the rate and velocity of runoff through the basin spillway must
be determined for the 10 year storm assuming that the basin is completely full.
The flow path should be delineated on the plans. Any necessary conduit outlet
protection or other structures must be delineated and detailed.
39. Section 4.14 of the Standards states "there shall be no overfall from the
end of the apron to the receiving channel." Please provide a stable flow path
by extending the pipe, headwall, and outlet protection out to the stream. If
this solution is not feasible, the District may be able to accept the current
discharge point if the routed 10 year peak discharge is sufficiently reduced and
a scour hole is designed for outlet protection. If this alternative becomes
necessary, please add a note to the plans which states that any erosion between
the scour hole and the receiving waters will be repaired immediately.
40. In summary form show how the project meets the Residential Site Improvement
Standards.

1. All applicable erosion and sediment control practices shall be in place prior
to any grading operation and/or installation of proposed structures or
utilities.
2. Soil erosion and sediment control practices on the plan shall be constructed
in accordance with the Standards for Soil Erosion and Sediment Control in New
Jersey.
