The land disturbance proposed with this plan does not include the construction of a single-family
home and is therefore not exempt from VSMP requirements [§17-303.C]. However, since the
driveway is for the establishment of the first single-family dwelling on the subject parcel, a SWM
agreement in lieu of a plan is allowed [§17-403.B], but all other VSMP documents are still
required (ESC plan, SWPPP and PPP).
Please submit a VSMP application and a VSMP fee of $171.60, with proof of payment, which is
in addition to the fee for a Mitigation Plan review. The Mitigation Plan review fee has been
received. Please indicate that you are resubmitting and include the project number listed above
on the form.
County Code section 17-410 and Virginia Code §62.1-44.15:34 requires the VSMP authority to
act on any VSMP permit by issuing a project approval or denial. This project is disapproved. The
rationale is given in the comments below. The application content requirements can be found in
County Code section 17-401.
A. Stormwater Pollution Prevention Plan (SWPPP)
The SWPPP content requirements can be found in County Code §17-405. A SWPPP is required
even though a SWM plan is not.
1. Single Family SWPPP not submitted. Provide a completed Single Family SWPPP. Please refer to
the following link for the Single -Family Home SWPPP template, which may be used for
this project:
https://www.a I bema rle.org/home/showpubl isheddocu ment/2662/637539044923470000
B. Pollution Prevention Plan (PPP)
A PPP is required even though a SWM plan is not required. PPP content requirements
can be found in County Code §17-404.
1. PPP not submitted. Include PPP requirements on the plan sheets.
C. Stormwater Management Plan (SWMP)
VSMP Regulation §9VAC25-870-108 requires the VSMP authority to approve or disapprove a
SWMP. A SWM plan is not required for this project because the land disturbing activity is for the

purpose of establishing a single-family dwelling and the Administrator has determined an
agreement in lieu of a stormwater management plan is allowed [§17-403.B].
1. Submit a completed and executed SWM Agreement in Lieu of a plan form with this
application. An additional fee for this agreement is NOT required. Refer to the agreement
linked below:
https://www.a I bema rle.org/home/showpubl isheddocu ment/2710/637539045240170000
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 the reasons noted below. The erosion control plan content
requirements can be found in County Code §17-402.
1. Revise note on Sheet 1 stating "Limits if Disturbance...." to "Limits of Disturbance...". Also,
add to the end of 'Qualifies for agreement in lieu of plan for SWMp/an"the following:
"because the driveway is being constructed for the purpose of establishing the first
single-family dwelling on the subject property [§17-403.B]:"
2. Show the area for each area of disturbance. Silt fence drainage areas must not exceed
approximately '% acre per 100-ft of SF (VESCH). Sediment traps may be required where
drainage areas exceed design standards or at discharge points to the stream.
3. Silt fence should be installed parallel with contours (VESCH). Replace silt fence with
diversions where appropriate and add a typical diversion detail to the plan set.
4. Add TS and PS symbols on plan where disturbance occurs and add the TS detail to the
plan set (VESCH).
5. Driveway Typical section on Sheet 2 indicates 3:1 side slopes for the drainage channels
but the detail on Sheet 4 indicates 2:1 side slopes. Please reconcile.
6. Show the slope of the driveway on the plan and provide a note that the driveway cannot
exceed 16% [§18-4.6.6].
7. It is suggested to confirm that the home site is large enough. Provide enough area for the
actual home that the owner wants to build, including outdoor areas, driveway pad, etc. If
the area of land disturbance exceeds 1 acre, a SWM agreement in lieu of a plan may still
be allowed considering the purpose of this disturbance is for the establishment of a
single-family home [§17-403.B]. It is recommended to provide as much area as is needed
for the home site so that additional grading of the hillside is not required later. The VSMP
fee is the same for LDAs under 5 acres if for the purpose of establishing a single-family
home [§17-208].
8. Add "Related approvals: FDP202100003" to the floodplain note on Sheet 1.
9. Provide a section of each bridge to clearly show and note that no work is to occur within
the stream banks.
10. Explain how construction of the bridges will be completed without having to drive
through the streams. Submit a copy of the ACOE permit with this application. If access
will be provided by some other means, indicate this on the drawings.
11. Confirm matchlines are correct. Matchline on Sheet 2 references Sheet 3. Should the
upper'window' reference the lower'window', and the lower'window' reference Sheet 3
on the right side of the plan? Sheet 3 doesn't show a matchline.

12. Just for information, there are typos in the notes on Sheet 3.
13. Show the limits of the stream buffer on Sheet 4.
14. Add "WPO202100068" to the cover sheet.
E. Mitigation Plan (MP)
1. Combine the mitigation plan with the ESC plan set. Add the mitigation sheets to the
sheet list and update sheet numbers accordingly. Revise the title of this drawing set to be
"Erosion & Sediment Control Plan and Mitigation Plan." This makes it easier for
inspectors to have one set of drawings in the field to use for inspections and
recordkeeping.
2. Add a column to the tables on Sheet 2 identifying which plants are canopy trees,
understory trees, and shrubs. Provide a table/calculation showing that the ratio of these
plants meets the ratio as noted in Appendix D of the Riparian Buffers Guidance Manual.
3. Include page C-1 from Appendix C of the Riparian Buffers Guidance Manual in the plan
set. Link to the manual:

The VSMP 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 or submit all documents online.
Engineering plan review staff are available from 2-4 PM on Thursdays, should you require a
meeting to discuss this review.
Process:
After approval, erosion and sediment control and stormwater management improvements and
proposed mitigation plantings must be bonded. The bonding process begins when the plan is
approved and the applicant submits a bond estimate request form and fee to the Department of
Community Development. A plan reviewer 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 need to be completed by the owner and submitted
along with cash, certificates or sureties for the amounts specified. The agreements will need 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.
After bonding is complete, county staff enters project information in a DEQ database for state
application processing, if a DEQ permit is required. DEQ reviews the application information
based on local VSMP authority approval. At this time, the DEQ portion of the application fees
will need to be paid directly to the state. For fastest processing, this is done electronically with
Engineering Review Comments

the emails provided on the application. DEQ should notify applicants with instructions on how to
pay fees. When DEQ approves the application, they will issue a permit coverage letter, which
must be posted at the construction site.
After DEQ coverage is issued, via the coverage letter, 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. The form identifies the contractor and responsible land
disturber, and the 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 joint VSMP and grading
permit will be issued by the County so that work may begin.
