Erosion Prevention and Sediment Control Notes

1. Contractor shall be responsible for complying with all State and Local erosion prevention and sediment control standards and permit requirements during construction.

2. The limit of disturbance shall be clearly defined by Contractor's surveyor prior to clearing. Erosion and sediment control devices shall be established to trap sediment on site.

3. Clearing and grubbing shall not begin until disturbance limits and sediment controls are in place. All roots, stumps and deleterious materials shall be removed from the site. The Contractor shall minimize the amount of disturbed land at any given time.

4. All erosion control shall be placed as shown on the drawings or as ordered by the Engineer. The Contractor shall maintain the erosion control measures until the Engineer is satisfied that permanent ground cover is established and that further measures are not required. It shall be the responsibility of the Contractor to employ appropriate erosion control as shown on these drawings and any other measures as necessary to trap sediment on site. Refer to permit maintenance and inspection requirements.

5. All areas of disturbance shall be permanently or temporarily stabilized as soon as possible and within 48 hours of final grading. All areas of disturbance shall be at least temporarily stabilized daily during winter construction unless the following exceptions apply:

a. Stabilization is not required if earthwork is to continue in the area in the next 24 hours and there is no precipitation forecast in the next 24 hours.

b. Stabilization is not required if the work is occurring in a self-contained excavation (i.e. no outlet) with a depth of 2 ft. or greater (e.g. house foundation excavation, utility trenches). Stabilization measures shall include mulch and netting, erosion control matting, crushed stone, gravel, or pavement.

6. Unless specifically indicated on the plans acceptable methods of stabilization shall include:

-Mulching - 2 tons per acre. Approximately 2" uniform thickness. Only allowed on relatively flat areas with minimum upslope watershed. Mulch must be properly secured with netting to prevent material from being blown away by wind (windthrow).

- Hydroseeding* - Applied at the manufacturer's recommended application rate. Contractor shall provide evidence of proper application rate. Hydroseeding must be accompanied by erosion control matting in areas of concentrated flow.

- Erosion control matting - S75BN matting may be applied to all finish graded sloped areas in lieu of seed and mulch.

- Crushed stone or crushed gravel - Typically used for temporary access roads and construction staging areas.

7. The Contractor shall use water for dust control.

8. The Contractor shall provide inlet protection around all catch basins (existing or new) that collect construction site stormwater runoff. At a minimum, MarshMat coir inlet filters shall be installed over all catch basin grates. Additional inlet control shall be installed as identified on the plans or as warranted during construction. Inlet protection must be maintained until final stabilization has been reached.

9. A stabilized construction entrance (See Detail) shall be installed and maintained at all construction access locations if construction vehicles travel off the existing hardscape. Contractor shall be responsible for installing crushed stone to provide stable areas for construction vehicle traffic, staging, and storage. The Contractor is responsible for providing and maintaining sufficient stone to prevent rutting and sediment tracking.

10. Any paved roads used by construction vehicles shall be swept daily, or at a greater frequency, if dirt or gravel is tracked from the site onto Municipal Streets. The swept debris shall be immediately removed from face of curb if applicable.

11. All temporary erosion and sediment control measures shall be removed within 30 days after final stabilization or after the measures are no longer needed, unless otherwise authorized.

12. All sediment removed from sediment control practices shall be placed in an approved soil disposal area.

13. All areas that do not have established vegetation by October 15th must be stabilized in accordance with the Winter Stabilization requirements outlined in the Low Risk Site Handbook. See Details.

14. After permanent seeding the Contractor shall be responsible for watering to ensure adequate vegetative growth.

15. The Contractor shall be responsible for providing all necessary temporary construction fencing, temporary roads, staging areas, etc., necessary to complete the work.

16. Water from dewatering activities that flows off site must be clear. Water must not be pumped into storm sewers unless the water is clear.

17. The erosion prevention and sediment control practices shown on these plans are the minimum required for the project. The Contractor shall employ as many best management practices as necessary to prevent soil from leaving the construction site. If evidence is found of sediment tracking or eroded soil leaving the construction site, the Engineer may direct Site Contractor to implement additional best management practices at no additional cost to Owner.

18. The Contractor shall be responsible for all inspection and maintenance of the erosion prevention and sediment control practices for the project.

1. ALL AREA DISTURBED AND ALL AREAS WITHIN THE CLEARING LIMITS SHALL BE

GRADED AND COVERED WITH A MINIMUM OF 4" OF LOAM TOPSOIL. THE AREAS TO BE

LOAMED SHALL BE FREE AND CLEAR OF ROOTS, WASTE MATERIAL AND OTHER

DELETERIOUS MATERIAL. TOPSOIL SHALL BE SPREAD AND LIGHTLY COMPACTED TO

A DEPTH OF 4". TOPSOIL SHALL BE APPROVED BY THE ENGINEER. ALL SIDE SLOPES

ARE TO BE LOAMED.

2. ALL TURF ESTABLISHMENT SHALL BE IN ACCORDANCE WITH SECTION 651 OF THE VT

STANDARD SPECIFICATIONS 2018 AND VT AIR NATIONAL GUARD SPECIFICATIONS.

MULCHING SHALL FOLLOW SEEDING BY NO MORE THAN 24 HOURS.

3. THE CONTRACTOR SHALL NOT DISTURB ANY GROUND BETWEEN OCTOBER 15TH

BETWEEN APRIL 15TH WINTER MONTHS, UNLESS APPROVED BY THE ENGINEER.

4. TEMPORARY SILT FENCE SHALL BE ERECTED PRIOR TO ANY CLEARING OR

CONSTRUCTION. FENCING MAY BE ERECTED IN PHASES, BUT IN NO CASE SHALL

GROUND DISTURBANCE PROCEED FENCING. SPECIAL AREAS MAY BE DESIGNATED

BY THE OWNER FOR PRESERVATION OF EXISTING TREES. THESE AREAS SHALL BE

THE CONTRACTOR'S RESPONSIBILITY TO INSURE NO DAMAGE IS DONE TO

DESIGNATED TREES.

5. EXISTING PLANTINGS ARE LOCATED IN GENERAL AREAS AS SHOWN ON THIS PLAN.

CONTRACTOR SHALL PROTECT PLANTINGS SO AS NOT TO DAMAGE THESE OR THEIR

ROOT SYSTEMS.

6. SLOPE STABILITY BASED UPON UNSATURATED SOIL CONDITIONS. IF DURING

CONSTRUCTION SATURATED SOILS ARE ENCOUNTERED, CONTACT THE ENGINEER

IMMEDIATELY.
