County Code section 17-410 and Virginia Code §62.1-44.15:34 requires the VSMP authority to act on any
NISN4P VESCP permit by issuing a project approval or denial. This project is denied for reasons listed
below. The VESCP application content requirements can be found in County Code section 17-402.
A. Stormwater Pollution Prevention Plan (SWPPP)
The SWPPP content requirements can be found in County Code section 17-405. A SWPPP must contain
(1) a PPP, (2) an ESOP, (3) a SWMP, and (4) any TMDL measures necessary.
1. Provide SWPPP, given potential for erosion. Use Albemarle county SWPPP template. Link:
http://www.albemarle.ore/uDload/imaees/forms center/departments/Community Development/fonns/Eneineerine and
WPO Forms/Stormwater Pollution Prevention Plan SWPPP template.pdf
B. Pollution Prevention Plan (PPP) — See above.
The PPP content requirements can be found in County Code section 17-404.
1. Please ensure PPP Exhibit identifies:
a. Rain gauge
b. Construction entrance that drains to a trapping measure
C. Stormwater Management Plan (SWMP) — NA: VESCP only
VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or disapprove a SWMP. This
plan is disapproved for reasons listed below. The stormwater management plan content requirements can be
found in County Code section 17-403.
D. Erosion and Sediment Control Plan (ESCP)
Virginia Code §62.1-44.15:55 requires the VESCP authority to approve or disapprove an ESCP. This plan
is disapproved for reasons listed, below. The erosion control plan content requirements can be found in
County Code section 17-402.
Sheet 1
2. Revise sheet index to list sheet 4 as Phase II.
3. Revise plan title to include ref. to WPO2020-00026.
4. Include title sheet Note that the fill activity is subject to 18-5.1.28.
5. Include Note that the land disturbance activity is subject to 17-300 (VESCP).
6. Include Note that Engineering has determined the activity is not subject to 17-302 (VSMP).

7. An ESC Plan bond is required. Please submit bond estimate request form at earliest convenience. Link:

uest to Establish a Bond.pdf
Sheet 3
8. Silt fence bars entry to fill site; provide break in SF so haul trucks may enter.
9. Similarly, provide break in silt fence at base of 18' sediment trap weir.
10. Provide site -specific sediment trap profile. This is a substantial sediment trap. VESCH typical /generic
detail (sheet 6) is inadequate.
11. Where proposed grade ties to existing grade, there are new permanent channels. Evaluate channel capacity
/velocity against 2-, 10-yr events, respectively. Evaluate permanent channels for erosion. Provide /specify
stabilization matting /blanket, if needed, for permanent channels created by proposed final grade. (blue
arrows; images below)
Sheet 3:
Sheet 4

12. Acquire temporary off -site construction easement, TMP 71-21, if needed.
13. Revise design (as needed) to ensure no off -site erosive impact, or construction impact to TMP 71-21,
unless easement acquired to allow off -site construction. Runoff may not impact adjacent
parcels. Evaluate. Furnish calculations.
14. Provide channel cross -sections for permanent channels (north / south) created by proposed final grade,
sheet 4.
Sheet 4
15. Phase II diversion dike (DD) is impermissible as a permanent measure (it is a temporary ESC
measure). Provide, instead, a permanent grass -lined or stabilized channel capable of withstanding 2-yr
event runoff, capable of containing 10-yr event volume.
16. Certain sections of SF in Phase 11 lie upslope of final graded -disturbed areas, and are not strictly needed
(comment applies to sheet 3, as well).
17. Revise legend to include WR. Do not recognize this symbol in the VESCH.
18. Sheet 5: Few if any references to Stormwater Management on this sheet are necessary; majority of
references may be removed. Also, item 5, above.
19. Include code text at 18-5.1.28, Borrow, fill or waste areas (below), on the plans (except 18-5.1.28.b.6.,
since an Erosion and Sediment Control plan is required).
Ensure text is readable. Link to text:

The VESCP permit application and all plans may be resubmitted for approval when all comments have been
satisfactorily addressed. For re -submittals please provide 2 copies of the complete permit package with a completed
application form.
Process:
After approval, plan will have to be bonded. The bonding process is begun by submitting a bond estimate request
form and fee to the Department of Community Development. One of the plan reviewers will prepare estimates and
check parcel and easement information based on the approved plans. The County's Management Analyst will
prepare bond agreement forms, which will have to be completed by the owner and submitted along with cash,
certificates or sureties for the amounts specified. The agreements will have to be approved and signed by the County
Attorney and County Engineer. This may take 2-4 weeks to obtain all the correct signatures and forms.
If any easements are required, then after easement plat is recorded, the County can hold a pre -construction
conference. Applicants must complete the request for a pre -construction conference form, and pay the remainder of
the application fee (if any). The form identifies the contractor and responsible land disturber, and fee remaining to
be paid. This will be checked by county staff, and upon approval, a pre -construction conference will be scheduled
with the County inspector. At the pre -construction conference, should everything proceed satisfactorily, a grading
permit will be issued by the County so that work may begin.
County forms can be found on the county website forms center under engineering;
