About this file

Written by GovTribe AI · Dec 9, 2024

This is an Erosion, Sedimentation, and Pollution Control Plan prepared by Roberts Civil Engineering for Effingham County, Georgia for the I-07B Roundabout project at Blue Jay Road and Hodgeville Road in Springfield. The project involves construction of a roundabout intersection with a total project area of 3.59 acres, all of which will be disturbed during construction. The plans were issued on June 26, 2024 and include detailed drainage area maps, initial/intermediate/final ES&PC plans, checklists, notes, and construction details. The project location is at coordinates 32°15'13.33"N, 81°17'41.57"W.

The plans detail five drainage basins with outfalls ranging from 0.38 to 1.50 acres in size, with channel slopes between 0.20-0.40%. Technical specifications include temporary and permanent vegetative stabilization measures, mulching requirements, lime and fertilizer application rates, and erosion control best management practices. The documents include detailed construction timelines, sampling locations, and stabilization requirements for disturbed areas. The project engineer is Jessica Vick, P.E. (Level II Certification #0000062699) and the owner's representative is Angela Stanley of Effingham County.

THE DESIGN PROFESSIONAL WHO PREPARED THE ES&PC PLAN IS TO INSPECT

THE INSTALLATION OF THE INITIAL SEDIMENT STORAGE REQUIREMENTS AND

PERIMETER CONTROL BMPS WITHIN 7 DAYS AFTER INSTALLATION.

NON-EXEMPT ACTIVITIES SHALL NOT BE CONDUCTED WITHIN THE 25 OR

50-FOOT UNDISTURBED STREAM BUFFERS AS MEASURED FROM THE POINT OF

WRESTED VEGETATION OR WITHIN 25-FEET OF THE COASTAL MARSHLAND

BUFFER AS MEASURED FROM THE JURISDICTIONAL DETERMINATION LINE

WITHOUT FIRST ACQUIRING THE NECESSARY VARIANCES AND PERMIT.

AMENDMENTS/REVISIONS TO THE ES&PC PLAN WHICH HAVE A SIGNIFICANT

EFFECT ON BMPS WITH A HYDRAULIC COMPONENT MUST BE CERTIFIED BY THE

DESIGN PROFESSIONAL.

WASTE MATERIALS SHALL NOT BE DISCHARGED TO WATERS OF THE STATE,

CONTROL MEASURES SHALL BE IMPLEMENTED TO CONTROL OR TREAT THE

SEDIMENT SOURCE.

ANY DISTURBED AREA LEFT EXPOSED FOR A PERIOD GREATER THAN 14 DAYS

SHALL BE STABILIZED WITH MULCH OR TEMPORARY SEEDING.

DEFINITION

The establishment of temporary vegetative cover with fast growing seedings for seasonal protection on disturbed or denuded areas.

CONDITIONS

Temporary grassing, instead of mulch, can be applied to rough graded areas that will be exposed for less than six months. Temporary vegetative measures should be coordinated with permanent measures to assure economical and effective stabilization. Most types of temporary vegetation are ideal to use as companion crops until the permanent vegetation is established.

Temporary vegetation can, in most cases, be established without the use of mulch. Mulch without seeding should be considered for short term protection.

Refer to Ds1 - Disturbed Area Stabilization (With Mulching Only).

Irrigation

During times of drought, water shall be applied at a rate not causing runoff and erosion. The soil shall be thoroughly wetted to a depth that will insure germination of the seed. Subsequent applications should be made when needed.

Select a grass or grass-legume mixture suitable to the area and season of the year. Seed shall be applied uniformly by hand, cyclone seeder, drill, cultipacker seeder, or hydraulic seeder (slurry including seed and fertilizer). Drill or cultipacker seeders should normally place seed one-quarter to one-half inch deep. Appropriate depth of planting is ten times the seed diameter. Soil should be “raked” lightly to cover seed with soil if seeded by hand.

Mulching

SPECIFICATIONS

Grading and Shaping

Excessive water run-off shall be reduced by properly designed and installed erosion control practices such as closed drains, ditches, dikes, diversions, sediment barriers and others.

No shaping or grading is required if slopes can be stabilized by hand-seeded vegetation or if hydraulic seeding equipment is to be used.

Seedbed Preparation

When a hydraulic seeder is used, seedbed preparation is not required. When using conventional or handseeding, seedbed preparation is not required if the soil material is loose and not sealed by rainfall.

When soil has been sealed by rainfall or consists of smooth cut slopes, the soil shall be pitted, trenched or otherwise scarified to provide a place for seed to lodge and germinate.

Lime and Fertilizer

Agricultural lime is required unless soil tests indicate otherwise. Apply agricultural lime at a rate of one ton per acre. Graded areas require lime application. Soils can be tested to determine if fertilizer is needed. On reasonably fertile soils or soil material, fertilizer is not required. For soils with very low fertility, 500 to 700 pounds of 10-10-10 fertilizer or the equivalent per acre (12-16 lbs./1,000 sq. ft.) shall be applied. Fertilizer should be applied before land preparation and incorporated with a disk, ripper or chisel.
