Erosion Prevention and Sediment Control Plan Components


We Provide Erosion & Sediment Control Plans For Clients Throughout NYC Area

When it comes to an effective erosion prevention and sediment control plan, each one has the same components. This ensures everything is done correctly. The five components of these plans are a location map, a site plan of existing conditions, a grading plan and timetable for the construction, a site plan and timetable for the erosion prevention and sediment control, and lastly a short summary that describes the aforementioned plans. Let's take a closer look at each of these components, as well as a rundown of what makes up each of the erosion and sediment control plans.

Location Map

The location map shows the proximity of the project or worksite to any surface water bodies, roads, etc. This map typically also includes map of even greater detail and a USGS map. Here is what you will find on a location map:

  • project property lines.
  • critical natural or man-made features within 3000 feet of the project, like streams, ponds, wetlands, roads, buildings, and utilities.
  • sufficient nearby features that allows reviewer to locate the site for an inspection.

Site Plan of Existing Conditions

The existing conditions site plan is a plan that show the grading and features as they currently exist. This site plan also include a soils map. Here are some of the existing conditions you will find on this site plan:

  • existing topographic contours that at five feet or smaller interval.
  • water features & drainage-way.
  • general vegetative covers that are within 200 feet of the water features. Some common examples are field, forests, and grass areas.
  • vegetative cover types you find in all proposed disturbance areas, as well as areas receiving and treating runoff from the given construction site.
  • a soil map and key.
  • identification of sensitive areas, like steep slopes, erodible soils, and wet areas.
  • any structures, roads, and utilities.
  • property lines

Grading Plan and Construction Timetable

The grading plan and construction timetable shows the proposed finished contours and addresses that make up the project. In general, this timetable does not have to contain any exact dates. However, it should show how each phase of the project relates to the others. It should also show the steps you have taken in order to minimize the soil that is exposed at any one time. Here is what you will find on a typical grading plan:

  • existing and proposed topographic contours.
  • the limits of soil disturbance, as well as the method you will use to mark these limits on site.
  • areas of various construction phases, which includes both sequential and concurrent activities.
  • any proposed structures, utilities, and roads.
  • the location of topsoil stockpiles, equipment storage, staging areas, refueling & maintenance areas and stump disposal areas.
  • the disposal area location for excess soil. If it is off-site, include the map.
  • known boundaries for the undisturbed riparian buffers.
  • the scale, date, and elevation datum.
  • property lines.

Erosion Prevention & Sediment Control Site Plan and Timetable

In most cases, the erosion prevention and sediment control site plan and timetable is prepared using the grading plan as a base. The site plan shows the location of all of the erosion and sediment control measures being implemented. On top of that, it will show the timetable, which effectively charts the outline of the control measures. In some cases, it is possible to combine the grading and erosion control plans into one. Here is what you will find on a erosion prevention and sediment control site plan and timetable:

  • soil disturbance limits.
  • riparian conservation buffer limits, as well as the method you will use for demarcation of limits.
  • exact location of all structural erosion and sediment control measures with full details.
  • areas to be seeded and mulched.
  • pathways for storm water.
  • erosion control matting on the slopes that are greater than 3:1.
  • no obstructions running across contours or in areas of concentrated flow.
  • chart of inspection and maintenance schedule of the erosion control measures.
  • details of adequately protected storm sewer inlets.
  • show the details of a stabilized construction.

Summary of Plans

The narrative is simply a summary of the four previous plans. An effective narrative briefly describes the four plans. On top of that, it should highlight all of the erosion control measures and why they will be effective. And detail the worksite characteristics, as well as the planning stages of the erosion control methods. When it is complete, you have a general description of the upcoming project.

Also included in the summary are the site inventory and analysis, as well as the grading plan and timetable. Here are some more details regarding this summary.

Site Inventory & Analysis

site drainage characteristics with both up and down-gradient.
drainage, waterways, and anybodies of water.
topography, existing roads, buildings, and utilities.
vegetation and soils.
how close is it to natural or man-made water features.

Grading Plan and Timetable

description of proposed grading, including notes on seasonal limitations.
timetable of all major construction and earth change activities, including stabilization methods for winter
