EROSION & SEDIMENT CONTROL NOTES
ES -1: Unless otherwise indicated, all vegetative and structural erosion and sediment control practices will be constructed and maintained according
to the minimum standards and specifications of the Virginia Erosions and Sediment Control Handbook and Virginia regulations VR 625-02-00
ES -2: The plan approving authority must be notified one week prior to the pre -construction conference, one week prior to the commencement of
land disturbing activity, and one week prior to final inspection.
ES -3: All erosions and sediment control measures are to be placed prior to or as a first step in the clearing.
ES -4: A copy of the approved erosion and sediment control plan shall be maintained on the site at all times.
ES -5: Prior to commencing land disturbing activities in areas other than indicated on these; plans (including but not limited to, off-site barrow or
waste areas) the contractor shall submit a supplementary erosion control plan to the owner for review and approval by the plan approving
authority.
ES -6: The contractor is responsible for installation of any additional erosion control measures as necessary to prevent erosion and sedimentation
as determined by the plan approving authority.
ES -7: All disturbed areas are to drain to approved sediment control measures at all times during land disturbing activities and during site
development until final stabilization is achieved.
ES -8: During dewatering operations, water will be pumped into an approved filtering device.
ES -9: The contractor shall inspect all erosion control measures periodically and after each runoff -producing rainfall event. Any necessary repairs or
cleanup to maintain the effectiveness of the erosion control devices shall be made immedi(3tely.
Erosion Notes:
1) All Entrances except the approved construction entrance shall be blocked in such a manner as to not allow access to the site.
2) The developer shall reserve the right to install, maintain, remove and/or convert to permianent structure all erosion and sediment control
measures required by this plan regardless of the sale of any lot.
3) A video camera inspection is required for all storm sewers and culverts that are deemed' inaccessible to VDOT inspections and are to be
accepted into VDOT's maintenance and program and ownership. The video inspection shall be conducted in accordance with VDOT's video inspection
procedure and with a VDOT and/or county inspector present. In addition, if high-density polyethylene (HDPE) pipe or pipe system, the contractor

FOR EROSION & SEDIMENT CONTROL •
1. The plan approving authority must be notified one week prior to the pre -construction conference, one week prior to the
commencement of land disturbing activity, and one week prior to the final inspection.
2. All erosion and sediment control measures will be constructed and maintained according to minimum standards and specifications of
the Virginia Erosion and Sediment control Handbook and Virginia Regulations VR 625-02-22 Erosion and Sediment Control
Regulations.
3. All erosion and sediment control measures are to be placed prior to or as the first step in clearing.
4. A copy of the approved erosion and sediment control plans shall be maintained on the site at all times.
5. Prior to commencing land disturbing activities in areas other than indicated on these plans (including, but not limits to, off-site
borrow or waste areas), the contractor shall submit a supplementary erosion control plan to the owner for review and approval by
the plan approving authority.
6. The contractor is responsible for installation of any additional erosion control measures necessary to prevent erosion and
sedimentation as determined by the plan approving authority.
7. All disturbed areas are to drain to approved sediment control measures at all times during land disturbing activities and during site
development until final stabilization is achieved.
8. During dewatering operation water will be pumped into an approved filtering device.
9. The contractor shall inspect all erosion control measures periodically and after each runoff -producing rainfall event. Any necessary
repairs or cleanup to maintain the effectiveness of the erosion control devices shalt be made immediately.
10. All fill material to be taken from an approved, designated borrow area.
11. All waste material shall be taken to an approved waste area. Earth fill shall be inert materials only, free of roots, stumps, wood,
rubbish, and other debris.
12. Borrow or waste areas are to be reclaimed within 7 days of completion per zoning Ordinance Section 5.1.28.
13. All inert materials shall be transported in compliance with Section 13-301 of the code of Albemarle.
14. borrow, fill or waste activity involving industrial -type power equipment shall be limited to the hours of 7:OOAM to 9:OOPM.
15. Borrow, fill or waste activity shall be conducted in a safe manner that maintains lateral support, or order to minimize any hazard to
persons, physical damage to adjacent land and improvements, and damage to any public street because of slides, sinking, or
collapse.
16. The developer shall reserve the right to install, maintain, remove or convert to permanent Stormwater Management Facilities (where
applicable) and all erosion control measures required by this plan regardless of the sale of any lot, unit, building or portion of the
property.
17. Temporary stabilization shall be temporary seeding and mulching. Seeding is to be gat 75 lbs/acre, and in the months of September
to February to consist of a 50/50 mix of annual ryegrass and cereal winter rye, or in March and April to consist of annual Rye, or
May through August to consist of German Millet. Straw mulch is to be applied at EBOlbs/100SF. Alternatives are subject to approved
by the County Erosion Control Inspector.
18. Permanent Stabilization shall be lime and fertilizer, permanent seeding, and mulch. Agricultural grade limestone shall be applied at
90lbs/1000sf, incorporated into the top 4-6 inches of soil. Fertilizer shall be applied at 1000lbs/acre and consist of a 10-20-10
nutrient mix. Permanent seeding shall be applied at 180 lbs/acre and consist of 95% Kentucky 31 or tall fescue and 0-5% perennial
ryegrass or Kentucky bluegrass. Straw mulch is to be applied at 80lbs/100sf. Altematives are subject to approved by the County
EErosion Control Inspector.
19. Maintenance: all measures are to be inspected weekly and after each rainfall. Any damage or clogging to structural measures is to
be repaired immediately. Silt Traps are to be cleaned when 50% of the wet storage volume is filled/with sediment. All seeded areas
are to be re -seeded when necessary to achieve a good stand of grass. Silt fence land diversion dykes which are collecting sediment
to half their height must be cleaned and repaired.
20. All temporary erosion and sediment control measures are to be removed within 30 days of final site stabilization, when measures are
no longer needed, subject to approval by the County Erosion Inspector.
21. This plan shall be void if the Owner does not obtain a permit within 1 year of the date of approval. (Water Protection Ordinance
Section 17-204G)
22. Permanent vegetation shall be installed on all denuded areas within nine (9) months after the date the land disturbing activity
commenced. (Water Protection Ordinance Section 17-207B)

4VAC50-60-54 of the Virginia Stormwater Management Program (VSMP) Permit
Regulations requires that Stormwater Pollution Prevention Plan (SWPPP) be developed
for all regulated land disturbing activities. The SWPPP must include, but not be limited
to, an approved erosion and sediment control plan, an approved stormwater
management plan, and this Pollution Prevention Plan {PPP) for regulated land
disturbing activities, and a description of any additional control measures necessary to
address a TMDL as applicable.
The plan for implementing pollution prevention measures during construction activities
developed on this sheet must be implemented and updated as necessary. Any PPP
requirements not included on this sheet must be incorporated into the SWPPP required
by 4VAC50-60-54 that must be developed before land disturbance commences. This
PPP identifies potential sources of pollutants that may reasonable be expected to affect
the quality stormwater discharges from the construction site (both on- and off-site
activities) and describes control measures that will be used to minimize pollutants in
stormwater discharges from the construction site.
OTHER REFERENCED PLANS
SWPPP requirements may be fulfilled by incorporating, by reference, other plans. All
plans incorporated by reference become enforceable under the VSMP Permit
Regulations and General Permit VAR10 for Discharges of Stormwater from
Construction Activities. If a plan incorporated by reference does not contain all of the
required elements of the PPP, the operator must develop the missing elements and
include them in the SWPPP.
