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.
1. A SWPPP was not provided with this submission. Please submit a SWPPP for review. Ensure it
has the newest registration statement (attached to this comment letter).
2. Please state where the debris from the existing building will be taken.
3. The existing building appears to have a basement. Will fill material be brought to fill this in? Is
so, please specify where it will come from.
B. Pollution Prevention Plan (PPP)
The PPP content requirements can be found in County Code section 17-404.
1. A PPP was not provided with this submission. Please submit a PPP for review.
C. Stormwater Management Plan (SWMP)
VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or disapprove a
SWMP. This plan is disapproved, and the reasons are provided in the comments below. The
stormwater management plan content requirements can be found in County Code section 17-403.
1. A Stormwater management agreement needs to be executed before plan approval. Please contact
Ana Kilmer [akilmer@albemarle.org 434-296-5832 ext 32461 to complete this task.
2. Nutrient credits should be purchased before plan approval. Please contact Ana Kilmer
[akilmer@albemarle.org 434-296-5832 ext 3246] to complete this task.
3. Please add the WPO number (WPO202100003) on the cover sheet.
4. Topography should have been completed or field verified within the past year. Current date on

the cover sheet is April 2019.
5. Show the DB & PG for all existing easements and parcels.
6. Please provide signed and sealed retaining wall plans/details.
7. [Sheet C6.0] Please review drainage divides. This line in the existing and proposed conditions
below does not appear to follow contours:

8. Please provide a proposed cross section for the drainage behind the proposed wall.
9. Please show how the water behind the wall in the location shown below will be directed.
Concentrated water cannot be sent to the adjacent parcel.

10. Please explain the note for the "2' curb cut for stormwater overflow". What overflow is it
referring to?
11. Please show where roof drains will be located.
12. Please show calculations for the existing inlet that goes to Ex-100(spread, etc). The drive thru
lane appears to drain to it through the existing channel.
13. The existing channel to the existing inlet that goes to Ex-100 is cracked and needs to be repaired.
14. Please show the velocity of stormwater going through the channel referenced in the above
15. Please provide more details for the proposed SWM facility. Ensure there is adequate access for
maintenance to the facility.
16. Since 9VAC25-870-66 C.2.b. was used for flood protection, please show that the existing
conveyance systems currently experience localized flooding. If they do not experience localized
flooding, C.1 & C.3 must be used.
17. The proposed sidewalk near the front of the site does not appear to drain to analysis point 2 as
shown in calculations (post area 2).
18. Please provide this checklist on the plans:

A 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, 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. Please clearly show the extent of the managed slopes.
2. Ensure temporary seeding, dust control and permanent seeding are shown on all phases of the
plan.
3. [Sheet C2.1 ] This tree is not marked to be removed however it appears to be within the clearing

limits. Please clarify. %.
4. [Sheet C2.1] Please locate and show which trees behind the building and near the proposed wall
are to remain and which are to be removed. The treeline shown on the plans does not appear to be
accurate.
5. [Sheet C3.0] Please specify the retaining wall area as a critical erosion area.
6. [Sheet C 3.1] The limits of disturbance appear to go offsite on both adjacent parcels. Do you have
permission or an easement for this work?
7. Work and improvements appear to be proposed in the Virginia telephone and telegraph easement.
Do you have permission for that?
8. Please show a stockpile, laydown/staging and parking area.
9. Ensure perimeter controls are sufficient. For example, how will sediment not leave the site at this
location?
10. Please show that silt fence is limited to areas of sheet flow with %< acre per 100ft.
11. Please consider adding an initial phase to address the removal of the existing wall and building,
and installation of the new wall as the I' step. A sediment trap may not be necessary for this
phase, especially if the existing pavement is preserved.
12. Please revise the sequence of construction to be site specific.
13. Sediment trap weir outfall cannot be directed as currently shown.

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.
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 emalls 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.
County forms can be found on the county website forms center under engineering;
