APPROVAL OF THIS STANDARD SEDIMENT AND STORMWATER PLAN MAY BE GRANTED IF ALL OF THE FOLLOWING CRITERIA ARE MET:

Residential Construction <1.0 Acre Disturbed:

  1. The total land disturbance will not exceed 1.0 Acre on any individual lot within the proposed project.
  2. The proposed construction is for residential development that does not create common lands, common open space, or a public street.

Residential Construction > 1.0 Acre Disturbed:

    1. The proposed construction is for residential construction that does not create common lands, common open space, or a public street.
    2. The total land disturbance will not exceed 5.0 acres on any individual lot within the proposed project.
    3. One of the following will be met on any individual lot:
      1. Clearing of forest areas will not exceed 1.0 acre, or
      2. Equivalent forest area will be retained on the parcel for the portion of the forest clearing that exceeds 1.0 acre.

    Definitions:

    1. Forest” means a biological community dominated by trees and other woody plants covering a land area of one contiguous acre or greater, and that have at least 100 trees per acre with at least 50% of those trees having a 2 inch or greater diameter at 4.5 feet above the ground and larger. Forest does not include orchards or other stands of trees having a curve number equivalent to “woods-grass combination”. To determine whether a site meets the definition of a forest at baseline condition of 2012, the Department or its authorized Delegated Agency may use data from various sources, including but not limited to 2012 Land Use/Land Cover data, historic and recent aerial photography, field collected data, etc.
    2. "Impervious surface" means a surface which either prevents or retards the entry of water into the soil.
    3. "Land disturbing activity" means a land change or construction activity for residential, commercial, industrial, and institutional land development which may result in soil erosion from water or wind, or the movement of sediments or pollutants into state waters or onto lands in the State; or which may result in accelerated stormwater runoff, including, but not limited to, clearing, grading, excavating, transporting and filling of land.
    4. Residential Construction” means single family residence and auxiliary structures such as detached garages, sheds, pole barns, accessory dwelling units, and other structures that create additional imperviousness.

    Standard Plan for All Residential Construction

    Relevant links underlined below.

    Stabilization Conditions

    1. Following initial soil disturbance or redisturbance, temporary or permanent stabilization with seed and mulch shall be completed within 14 calendar days to the surface of all disturbed areas not actively under construction.
    2. Specific stabilization recommendations may be found in the Delaware Erosion and Sediment Control Handbook, 3.4.3 Standard and Specifications for Vegetative Stabilization.

    Standard Conditions

    1. Standard nutrient management plan recommendations will be followed for the project, during construction and throughout the life of the project.
      1. Application of lawn nutrients will be based upon the recommendations of a soil test.
      2. Nutrients will be applied only to turf areas, not impervious surfaces.
      3. Nutrients will not be applied directly before a runoff event.
    2. Discharges from rooftops will be disconnected using a method approved by the Department or Delegated Agency. For example:
      1. Individual downspouts that discharge to lawn, landscape area, or preserved open space or forested area.
      2. Discharges from downspouts can be collected in rain barrels or cisterns for reuse.
    3. Driveways, sidewalks, patios, and other impervious surfaces will be graded to sheet flow to lawn or other pervious areas to the maximum extent practicable.
    4. Construction site stormwater management best management practices will be used. Standard Detail and Specification DE-ESC-3.7.1 ESC For Minor Development will be followed.
    5. Construction projects exceeding 1.0 acre of total disturbance require submittal of a Notice of Intent (NOI) for Stormwater Discharges Associated with Construction Activity. A plan fulfilling Stormwater Pollution Prevention Plan (SWPPP) (DE-ESC 3.6.1 and 3.6.2) requirements must be developed to obtain general permit coverage for Stormwater Discharges Associated with Construction Activity.
    6. Approval of this Standard Plan does not relieve the applicant from complying with any and all federal, state, county or municipal laws and regulations.

        Construction Notes:

        1. Evaluate the Site
          1. Identify Vegetation To Be Saved
          2. Protect Trees and Sensitive Areas
        2. Install Perimeter Erosion And Sediment Controls
          1. Protect down-slope areas with vegetative filter strips
          2. Protect down-slope areas with silt fence
          3. Restrict all lot access to stabilized construction entrance to prevent vehicles from tracking mud onto roadways
          4. Install inlet protection on nearby storm drain inlets 
        3. Prepare the Site for Construction
        4. Salvage and Stockpile the Topsoil/Subsoil
        5. Build the Structure(s) and Install the Utilities
        6. Install Downspout Extenders
        7. Maintain the Control Practices
          1. Maintain all erosion and sediment control practices until construction is completed and the lot is stabilized
          2. Inspect the control practices a minimum of twice a week and after each storm event, making any needed repairs immediately
        8. Revegetate the Building Site
          1. Redistribute the stockpiled subsoil and topsoil
          2. Seed or sod bare areas
          3. Mulch newly seeded areas
        9. Remove Remaining Temporary Control Measures
