SECPS – Sediment and Erosion Control Construction Plan Submittal Checklist
Wake County Basin Removal Sequence
Wake County or jurisdictional municipality must grant permission to convert the sediment basin over to
stormwater use prior to completing any related work (a note in the construction sequence or elsewhere
on the plan should indicate this).
Show all Riparian Buffers [Article 9-21]; (Neuse:
[15A NCAC 02B.0233 & 0242]
Delineation of current FEMA boundaries (floodway, flood fringe & future/0.2%)
Delineation of flood prone soil areas
Location and type of all proposed stormwater management structures (grass swale, wet/dry detention
basin, filtering/infiltration basin, bioretention, etc.)
Standards and Requirements
By marking items with an “X”, applicant acknowledges potential standards to be applied to the proposed development.
Wake County UDO Article 10 - Erosion and Sedimentation Control Requirements
Erosion Control: This project will require a Land Disturbance Permit if it involves greater than one acre of
disturbance. See website for details.
10-20-1 Minimum Standards - All soil erosion and sedimentation control plans and measures must conform to
the minimum applicable standards specified in North Carolina’s Erosion and Sediment Control Planning and
Design Manual and the Wake County Sedimentation and Erosion Control Plan Review Manual. Erosion control
devices must be installed to prevent any offsite sedimentation for any construction site regardless of the size of
the land disturbance.
10-20-3 Operation in Lakes or Natural Watercourses -Land disturbing activity in connection with construction
in, on, over, or under a lake of natural watercourse must minimize the extent and duration of disruption of the
stream channel. Where relocation of a stream forms an essential part of the proposed activity, the relocation
must minimize unnecessary changes in the stream flow characteristics.
10-20-10 Standards for High Quality Water (HQW) Zones
Land-disturbing activities to be conducted in High Quality Water Zones must be designed as follows:
Uncovered areas in High Quality Water (HQW) zones must be limited at any time to a maximum total area
of 20 acres within the boundaries of the tract.
Maximum Peak Rate of Runoff - Erosion and sedimentation control measures, structures, and devices
within HQW zones must be planned, designed and constructed to provide protection from the runoff of
the 25-year storm.
Settling Efficiency - Sediment basins within HQW zones must be designed and constructed so that the
basin will have a settling efficiency of at least 70% for the 40 micron (0.04mm) size soil particle transported
into the basin by the runoff of that 2-year storm which produces the maximum peak rate of runoff.
Grade - The angle for side slopes must be sufficient to restrain accelerated erosion (side slopes no steeper
than 2 horizontal to 1 vertical if a vegetative cover is used for stabilization unless soil conditions permit a
steeper slope or where the slopes are stabilized by using mechanical devices, structural devices or other
acceptable ditch liners)
