RE: Rio Road VSMP Submittal
Kelsey,
Thanks for link and comment letter.
Please accept these minor
comments.
SWM
§62.1-44.15:35 requires documentation of 0.48 lb. nutrient credit purchase before offsite compliance option is
accepted. With this email, Albemarle County grants SWM Plan Approvalep nding documentation of nutrient credit
purchase. Approval releases an Applicant, signals there are no remaining (unmet design) requirements. CVS proposes to
purchase off-site nutrient credits. Albemarle County cannot approve VSMP without documentation of off-site nutrient
credit purchase. This is the single remaining SWM Plan comment. Proposed SWM Plan dated November 19, 2015 is
approvede� purchase of 0.48 lb. phosphorus credits. Note: please revise Stormwater Quality Note, CG -301, to
reflect 0.48 lb. load reduction requirement, rather than 0.41 lb. load reduction.
D. A VSMP authority shall allow offsite options in accordance with subsection I when:
I. Less than rive acres of land will be disturbed.
2. The postconst ruction phosphorous control requirement is less than 10 pounds per wear: or
3. The state permit applicant denicnstrates to the satisfaction of the VSNil PaLahority that (i) alternative site
designs have been considered that may accommodate ansite best management practices, (ii) onsite best
management practices hake been considered in alternative site designs to the maximum extent practicable, (iii)
appropriate onsite best management prariices %viII be implemented, and (i %r) full compliance with
postdevelopment nonpoint nutrient runoff compliance requirements cannot practicably be met onsite. For
purposes of this subdivis[on, if an applicant dewonstrates onsite control of at least 75 percent of the required
phosphorous nutrient reductions, the applicant shall be deemed to have met the r+equ1renients of c1:I4ises {i)
through (Iv),
E. Documentation of the app] i ca nt's acquisition of nutrient credits shall be provided to the VSNIP authority and
the Department in a certification from the credit provider documetit ing the number of phosphorus nutrient
cmdIts acquired and the associated ratio of nitrogen nutrient credits at the credit -generating entity. lxndI Ilie

Kelsey,
Thanks for your patience.
Engineering review comments (SWPPP) -13 Oct, 2015 —listed, below.
Please accept 4 remaining comments —all other comments Addressed.
Thank you
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.
SWPPP —It may be difficult to reference comments; pg. # with revisions would help.
(Initial Site Plan comment (437) recommending Attached SWPPP template would simplify.)
1. I.A. — "The operator will file a complete registration statement for coverage under a VPDES General Permit for storm water
discharges from construction activities with the Virginia Department of Environmental Quality at least 15 days prior to
commencement..." This is not the process. Please call to discuss. Reference to fee is incorrect. —Ref. Albemarle County
Code 17-208.
2. I.B. —"Land disturbing activities cannot commence until verification of coverage is received by the Operator," is partial
reference to land clearing prerequisites. Land disturbance contingent upon a series of review approvals. Ref. 17-417.
3. Provide signed General VPDES Permit Registration. -17-401.C.
4. I.F. —List and identify individual/s by name —ref. VAR10 Part II.F. L/Part ILAAA. —May list Kimley-Horn technical
personnel, until a contractor is selected.
5. I.H. —Include copy of General Permit with SWPPP. Ref. Attached 17-p. SWPPP template/Sec. 11. (Rev. 1) Not addressed
—Ref to web -link is insufficient. Public has right to view VARIO General VPDES Permit with on-site SWPPP.
6. I.K. —If SWPPP to be revised, recommend replace spiral binder with 3 -ring binder.
7. II — Introduction: "This SWPPP has been prepared for land disturbing activities associated with the construction of Rio Road
in Albemarle County, VA," is inaccurate. It is prepared for CVS site. Revise.
8. II/Scope —"Where the Operator seeks to terminate coverage because the site has reached final stabilization, termination will
become effective upon concurrence by the VSMP Authority, or after 60 days from the submittal of the NOT [Notice],
whichever occurs first." This is partial representation of conditions found at VAR10 Part I.F.(2) There is risk terminating a
VPDES permit without concurrence of local program authority. Ref VAR 10 Part I.F.1./2./3. for complete description of
VPDES permit termination process.
9. II/Scope —"Allowable non -storm water discharges that may occur during construction on this project, which would therefore
be covered by the General Permit, include: 3. Water used to wash vehicles or control dust where detergents are not
used." True, if wash waters are collected/detained and do not reach receiving streams.
10. II/Scope —"The Operator referred to in this SWPPP is the entity noted on the VSMP registration statement." Provide
Registration statement. Identify operator.
11. III, Project Description, B. Sequence of Construction: Schedule an on-site pre -construction meeting." This is inconsistent
with local program authority procedure. Preconstruction meetings are held at Albemarle County Office building —please
revise.
12. III.B: —"Upon demolition of the parking lot and curb and gutter a diversion dike should be installed parallel with Route 29 to
maintain positive drainage to the inlet shown to remain." Ref. ESC Plan comments 7./8. Revise SWPPP Seq. of
Construction accordingly.
13. III.B. —"Once phase I measures are in place and functioning properly, clearing within the limits of disturbance shown in
phase ii can commence. Demolish buildings, asphalt, concrete and curb and gutter." Delete second sentence. Demolition
has occurred with phase I.
14. III.C. — "The project site consists of 1.535 acres with a disturbed area of 1.69 acres." Project site cannot be less than
disturbed area. Revise.
15. III.G.9: [The selected erosion and sediment control drawings, grading and drainage drawings, and /or erosion and sediment
control narrative provided in Appendix G illustrate/outline the following:] 9. "Location of all off-site materials, waste,
borrow or equipment storage areas covered by the plan." This statement is inaccurate. Drawings/Appendix G [Appendix
contains reference to 3 plan sheets; this could be accomplished with direct reference to plan sheets in body of SWPPP] do not
outline items listed. Revise.
16. IV. Site Description: —"Included as part of this SWPPP in Appendix G are selected project construction drawings. Please
refer to them for detailed site information." Reference to drawings is insufficient: Provide I V X 17" Exhibit. (Recommend
ESC Plan as template.) Show solid/non-hazardous waste dumpster; sanitary facilities (port -a john); solvent -paint storage;
concrete wash-out; on-site fuel storage. DEQ, during periodic inspections of active projects, instructs on importance of an
Exhibit that shows location of these features. All should drain to containment. For example, silt fence downstream of port -a -
john. Concrete wash-out, dumpster draining to trapping device (lined, in case of concrete wash-out). On-site fuel storage
berm with 10ml liner, sized to hold fuel volume + 2 yr. storm event. .PDF samples available. Exhibit is not intended as a
detailed design, but to show containment and locations which may change over time. Exhibit is a construction aid and
resource protection/inspection management tool. (Rev. 1) Partially addressed. CE -101: provide labels that indicate
containment for on-site fuel storage, concrete washout (I may have overlooked).
17. IV.C. Rainfall information —Locate rain gauge on SWPPP Exhibit/initial location. Contractor is free to change location, if
change is noted on Exhibit.
18. IVY. Threatened or Endangered Species or their Critical Habitat —Obtain T&E species clearance/project approval as required
from applicable state (VDGIF/DEQ) or federal agencies (USFWS). (Rev. 1) Not addressed. James Spinymussel is benthic,
and will not be observed during construction. Coordination is not required if impacts to these species' habitats will occur, but
is required to avoid impact to species' habitats. Obtain project clearance/project approval from VDGIF, DEQ, and USFWS.
19. IV.G. —ESC Plan: "...include a temporary stone construction entrance." Revise to read paved entrance. (Rev. 1) Partially
addressed. As follow-up, please list sediment trap with other listed measures.
20. IV.H. —Permanent stormwater controls —Ref. SWM Plan comment item #4 — Revise SWPPP at this location
accordingly. Furnish evidence. Provide details that constitute a SWM Plan.
21. IV.H. —Reference to Appendix I (as with Appendix G) is reference to plan sheets better accomplished directly, with text. Tv
and Tc calculations are provided (CG -301). Quantity calculations are absent, not provided. Revise text for accuracy.
22. V.C. —Please title this portion of SWPPP `Construction Phase "Best Management Practices" Pollution Prevention Practices,'
for local/state DEQ inspector benefit. DEQ looks for PPP section of SWPPP. —Re£ county template, Sec. 6.
23. VII —"The Operator may install a rain gauge at the site..." This statement is inconsistent with IV.C. (#17, above). Revise.
24. VII — "All modifications to the SWPPP document and approved plan will be noted on the construction plans." Revise to read
"will be noted on the SWPPP Exhibit."
25. VII —"If it is determined ... that there has been an upset or bypass of the control measures resulting in a release of sediment to
State waters, the Operator's Inspector shall report the bypass or upset to the Albemarle County Department of Community
Development..." Revise to include State notification.—VAR10, Part III.1.1./2.
26. VII —"Within five days of making the verbal report to the County, a written report shall ..." Revise to include State
notification.

Subject: SWPPP Questions: Seminole Trail / Rio Road CVS
John,
We are working through the SWPPP comments on the CVS project located at the corner of Seminole Trail and Rio Road
and had a few questions for you. If you can take a look at the items outlined below and see what you can respond to via
email, then we can either get on a conference call or set up a meeting to discuss the remaining issues.
SWPPP
■ Comment #1:
o What is the process you referenced? -outline of steps to receive grading permit once VSMP plan
approved: ESC bond request/estimate; bond process/posting; SWM Maintenance Agreement (NA); DEQ
database; coverage letter; schedule precon; remainder of fee (paid at precon); then, receive Grading
Permit.
o Which fee reference is incorrect? The referenced section appears to match what is listed in the SWPPP.
— true, but the columns provide clues to less explicit information. Recommend remove this section
altogether or replace with general statement concerning payment of fees. For disturbance greater than one
and less than 5 Ac: $1,350 to county due with Application (paid); $756 due to State just prior to coverage
letter issuance (required for VPDES coverage letter); $594 to County at preconstruction —total
=$1350. Three separate payments to two entities at three points in time.
Comment #16:
o Location of the solvent paint storage and onsite fuel location seems unnecessary and may not be
required —means and methods. We (local program) have been faulted by DEQ during inspections for
failure to identify SWPPP Exhibit/Activity locations, even for accepting a SWPPP proximate to impaired
waters that did not include increased inspection frequency. Location of potential pollutant sources with
respect to storm inlets/receiving streams is not means and methods. It is an initial location that a
contractor may change —we are trying at every step to eliminate impediments, not create them. I see your
point, but we need this —please provide.
■ Can we leave to contractor and add a note specifying this? As consequence of state warning to
our program, we do not create new requirements, but simply ask the minimum. The contractor is
free to change locations, but solvent/paint storage, sanitary facilities, dumpster, on-site fuel
storage, and concrete washout —these receive particular scrutiny during oversight
inspections. Thanks for asking —please provide.
• Comment #21:
o We have received storm design information from VDOT showing how our site was accounted for (0.85 C
factor was used). How should this be presented? —Electronically, e-mail or disc. Please add Note to
plans stating: SWM channel and flood protection information relating to VDOT design for the Rt. 29/Rio
Road interchange has been submitted to Albemarle County in response to request for design compliance
data.
SWPPP Stormwater Management Plan
0 Comment #3:
o Discuss existing detention system —the existing detention system will be removed as part of CVS' work.
We have coordinated with VDOT and their designers to verify that the detention system was ignored in
the design of their storm network. —I understand, please share written confirmation or details of VDOT
design approach in this regard. We need documentation tracing to VDOT design: A letter that provides
VDOT L&D/Drainage details that address this request directly.
• Comment #4:
o Same as #21 above — design information received from VDOT. How should this be presented? Same as
#21 above
SWPPP Erosion Control Plan
• Comment #7:
o Can sediment basin be omitted since two inlets will remain? Less than 1 acre will drain to each inlet and
sequence has been updated accordingly. —No. We've had unfortunate experience in the past with site
development immediately adjacent to primary routes —when minor controls fail (in this case, RW
diversion), it is havoc. I cannot imagine a RW diversion working in this location. It is less a matter of
design than execution. Request for sediment trap is from the County Engineer. We appreciate expense,
but RW diversion at Rt. 29/Rio Road ramp entrance to site cannot be approved. We can discuss on
conference call, but are not open to persuasion. We must protect this brand new heavily -trafficked
interchange facility.
Thanks,
Kelsey Westwood, E.I.T.

B. VSMP: SWPPP: Stormwater Management Plan (WPO201500059)
VSMP Regulation 9VAC25- 870 -108 requires the VSMP authority to approve or disapprove a SWMP. This plan is
disapproved for reasons provided in comments below. The stormwater management plan content requirements can be
found in County Code section 17 -403.
1. Please remove sheets: CS -101, CS -501, CP -101, CP -102, CP -501, CL -101, CL -102, CT -500, CT -501.
2. Revise Title to include: WPO201500059NSMP. Delete `Final Site Plan' in plan set Title.
3. CE -101: Explain label "Ex. Detention system to be removed." (Green box, image below) There is no
mention of an existing detention system in SWM Narrative, CG -301. If an existing detention system is
being removed (despite lack of existing detail), a SWM plan typically requires Narrative that addresses
Q2 /Q10 increase, if there is any increase. SWM plans do not have a regulatory option of removing detention
without due consideration. Assurance that VDOT Rt. 29 interchange project has been designed with (post -
developed) CVS site runoff in drainage capacity calculations requires supporting documentation.
4. 12 -Aug 2015 Kimley »Horn response letter: "There is an existing detention system serving the corner parcel,
however, no details or specifics on the system have been able to be located. Per discussions with VDOT the
detention system can be removed as no control for the site is modeled in the calculations for the storm drain
along Route 29." Please provide additional details. CG -301: (SWM Assumptions/Notes) "Design plans for
VDOT's grade separated interchange are underway and the proposed improvements are slated for
construction prior to commencing CVS construction. As part of VDOT's work they will be responsible for
modifying the storm network in Route 29 to handle the roadway improvements as well as convey drainage
from the adjacent parcels. As a result, VDOT will have provided an adequate outfall to the subject site
capable of satisfying the state's channel and flood protection criteria." This statement requires support.
Provide quantitative design data that supports this statement. Similarly, support Narrative /SW Quantity:
"Channel protection and flood protection criteria are met as VDOT has accounted for the sites
imperviousness as part of their design for the Route 29/Rio Road grade separated interchange," and "VDOT
has analyzed the storm network in Route 29 and verified capacity up to the subject site." If VDOT has
accounted for the site's imperviousness and if impervious area is set to decrease under the proposed
development, then whether existing detention is removed or not is beside the point (circumstance sufficient
to address item #3). Provide water quantity compliance demonstration per 9VAC25- 870 -66 (document
VDOT design, provide analysis, etc.). These statements do not of themselves ensure proposed development
is compliant. Given removal of existing detention, it appears possible (if not likely) that post - developed
Q2 /Q10 may increase, which, absent specific evidence of VDOT allowance in interchange design, is non-
compliant.
5. CG -301: Evidence of purchase of nutrient credits from Wildwood Farm is required prior to VSMP
Approval. [Applicant response: Noted. This does not alleviate need for evidence of purchase. Approval
requires evidence of purchase.]
6. CG -301: Redevelopment worksheet Ac. =1.54. Revise to LOD Ac. =1.69. Post - developed land cover must
include Acreage disturbed, at a minimum.

Demolish, construct, stabilize upslope areas; place stone aggregate base prior to removing sediment trap.
Demolish remnant pavement at entrance to Rt. 29 ramp as a Phase II ESC item. Place remaining aggregate
stone prior to paving. Other sequences may work, but this site cannot be opened to 1.69 Ac. draining to the
existing inlet and pipe (to remain). The grades don't work. Entire open site draining to inlet (to remain) is
impractical. Proposed design cannot be approved. Design and recommended sequence have been reviewed
by the County Engineer. A sediment trap is not a recommendation. It is a requirement.
8. CE -101: Revise Note 5 — Proximity to U.S. Rt. 29 makes diversion dike parallel with Rt. 29 impractical.
This design cannot be approved. Dike failure this close to Rt. 29 has severe impact potential. Also, ref.
VESCH, p. III -33, Design Criteria, 1. "The drainage area shall be no greater than 1 Ac."
9. CG -101: Indicate storm inlet drain `F' /`D' drainage divide —show as dash, etc. Provide Phase 11 E &S Plan
measures that protect Rt. 29; for example, diversion dike parallel with Rt. 29 ramp, as proposed with Phase
I E &S. Add sequence of construction notes to preserve existing storm inlets closest to Rte. 29 as long as
possible. These convey runoff offsite. Once existing inlets are demolished, provide sequence that provides
adequate ESC measures at points of entry to storm lines A to V1, and X2 to V4. Furnish detail /s for ESC
measure /s that capture and filter runoff during construction. Runoff to Rte. 29 is impermissible.
10. CG -101: Phase II probable construction sequence — Delete Note 2 (demolition complete).
Engineering plan review staff are available from 2 -4 PM on Thursdays, should you require a meeting to discuss
this review. Plan review staff available at 434 - 296 -5832 (- 0069) should you have questions.
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 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 request a pre - construction conference by completing a 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;
