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 denied. The
rationale is given in the comments below. The application may be resubmitted for approval if all
of the items below are satisfactorily addressed. The VSMP 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 section 17-405. A SWPPP must
contain (1) a PPP, (2) an ESCP, (3) a SWMP, and (4) any TMDL measures necessary.
A SWPPP was not found in the submittal package. Please use the Albemarle County SWPPP
template for help with this requirement. The template can be on this link:
http://www.albemarle.org/upload/images/forms_center/departments/Community Development/for
ms/Engineering and _WPO _Forms/Stormwater Pollution _Prevention _ Plan_ SWPPP_template.pdf
2
Documents in the SWPPP have not been signed by the owner. The SWPPP documents can be left at
the front office counter for up to 2 days. Please let me know when I can leave the documents at the
front counter for signature.
B. Pollution Prevention Plan (PPP)
The PPP content requirements can be found in County Code section 17-404.
PPP appears to be addressed on the plan sheet. The County would prefer the SWPPP template
utilized due to this document being a "Living" document that is to be kept up to date with the
SWPPP as the site develops. However, the plan will suffice as long as it meets the Virginia DEQ
standards and regulations. Additional document pages may need to be added to the plan as the
project progresses.
Project description appears addressed at this time. The PPP will need to show the locations on the
plan for the preconstruction meeting. The owner, contractor and inspector can address this issue at
the Pre -construction meeting.

C. Stormwater Management Plan (SWMP)
VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or disapprove a
SWMP. This plan is approved, and the reasons are provided in the comments below. The
stormwater management plan content requirements can be found in County Code section 17-403.
A SWM agreement will be required for final approval. Please contact Ana Kilmer
(akilmer(c-r�,albemarle.org ) for information and SWM Agreement template requirements.
If an existing SWM agreement exists for this site then it may need to be updated to match
this plan and information prior to issuance of a grading permit. Please contact Mrs. Ana
Kilmer (akilmer(&albemarle.org) for additional information.
D. Erosion and Sediment Control Plan (ESOP)
Virginia Code §62.1-44.15:55 requires the VESCP authority to approve or disapprove an ESCP.
This plan is approved, and the reasons are provided in the comments below. The erosion control
plan content requirements can be found in County Code section 17-402.
1. Existing site conditions are not shown correctly. Please show the actual existing site conditions.
This project is believed to be submitted to replace the existing site stormwater management and
should be explained in written form to better clarify the action instead of showing what might have
been previous site conditions.
2. Plan appears to show existing basin to be removed but does not address how the site will be
graded and armored from erosion. Please clarify on plan.
3. Please show the construction entrance location on the plan. The existing asphalt can be utilized if
denoted on the plan per VESCH.
4. Please show the limits and type of vegetation on the plan.
Comments appear addressed with this submittal. The basin removal will need to be performed in a manner
that does not allow for the discharge of sediment laden waters from the site. This will require coordination
with the County VSMP Inspector.
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.
Engineering plan review staff are available from 2-4 PM on Thursdays, should you require a meeting to
discuss this review.
Process;
After approval, plans will need 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 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.
Stormwater Management Facilities Maintenance agreements will also need to be completed and recorded.
The County's Management Analyst or other staff will prepare the forms and check for ownership and
signature information. The completed forms will need to be submitted along with court recording fees.
Engineering Review Comments
Page 3 of 3
After bonding and agreements are complete, county staff will need to enter project information in a DEQ
database for state application processing. DEQ will review 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 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. This should be copied to the county.
After DEQ coverage is issued, via the coverage letter, the County can hold a pre -construction conference.
Applicants will need to 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.

Tim,
I'd like to help,will work on/off this weekend—brought enough past-due projects home to keep me going(10+projects).
If you like, consider items below, and respond. I'll do what I can. Please do not consider this a review... it's a preview.
Items:
1. C-602—Why is there a club-head shape shown as Limits of Minor Site Plan Amendment? What features are
within Limits at this location? Anything VSMP-related?
2. C-601 —Show proposed contours required to construct New Office building/New Asphalt parking,unless pad
ready/no proposed grading.
3. List/label Limits of Disturbance(=x.xx Acre).
4. Show drainage divides,if any.
5. Provide SWPPP [Template Attached]
6. Note below asks whether"the county would have any objections to using this BMP method." All DEQ BMP
Clearinghouse methods are available. Another option: offsite nutrient purchase,if: Area of disturbance<5 Ac,or
total phosphorus load reduction<10 lb/yr.
7. The more meaningful answer is whether county objects to this design. If you like, send: VaRRM .xls(file itself);
pre-/post-development drainage maps; Narrative;plan/profile(DETAILS) for new SWM basin; and sheet/s with
Construction-Maintenance Notes taken directly from the BMP specification/s. We require this. We do not
assume contractors have adequate guidance to construct BMPs. We do not consider reference to on-line design
specifications adequate to serve developer, contractor,or inspector needs.
8. Provide Qio(CFS)entering Spec. 2 BMP/ELS. Provide length of ELS. Length of ELS Lip= 13 lin. Ft.per each
1 cfs of inflow if area has 90%Cover. (Table 2.2.)
9. Identify soil types.
10. Correlate NRCS soil legend/soil Map names with hydrologic soil group/s(Websoil survey-
http://websoilsurvey.sc.egov.usda.gov/App/WebSoilSurvey.aspx). Phosphorus reduction credit varies depending
upon Hydrologic Soil Group—A,B,C,D.

John,
We met a few weeks ago on the Earlysville Business Park site plan amendment. It was determined during that meeting
that since the Owner did not have a current DEQ land disturbance permit that the amendment would have to meet the
current regulations.
I have revised the SWM design to comply with current regulations. The water quality measure is BMP Spec No. 2 Sheet
flow.
Attached are plans showing the BMP. Can you review it and let me if the county would have any objections to using this
BMP method. If there are no objections then I will submit the plans and calculations for review and approval.
Given the confusion over this project I am trying to reduce the time it will take to get this approved. The Owner is quite
upset about how the requirements change every time we submit plans. Anything you can do to help would be
appreciated.
Thanks,
Tim Miller, P.E., L.S.
