VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or disapprove a SWMP. This
plan is approved pending recordation of a new filterra SWM facility easement; see items 2.b., 4.h., and 6,
below. The stormwater management plan content requirements can be found in County Code section 17-
403.
1. Easement Plat (C1 Note 3): Plat at deed bk.-pg. 4489-22 includes label reading: `* Easement is defined
with this plat but will be created and dedicated with a separate instrument.' Furnish deed bk. -pg. ref. to
recorded instrument that creates and dedicates north underground detention (at Costco) to public use
(Albemarle County, Grantee). (Rev. 1) Addressed.
2. Easement Plat (C_1 Note 4): Certificate of Plat at deed bk.-pg. 4135-217 is insufficient for WPO202000016
plan approval (WPO2011-00055 Amendment). Certificate of Plat, sheet 1 of 8, plat Note 8, may offer clue.
This note reads: `A Master Declaration will be prepared and recorded in conjunction with this plat. Please
see this Declaration for common shared rights and easements of all owners of these parcels.' Since
document at bk.-pg. 4135-215 is only a Certificate of Plat, please revise C=1 second Note 3 to include text
reference to a Certificate of Plat, rather than a Maintenance Agreement. Also:
a. Revise second note 3 to read Note 4. (Rev. 1) Addressed.
b. Provide bk.-pg. ref. to SWM Facility Maintenance Agreement for District Ave. biofilter. (Rev. 1)
Comment revised. As follow-up: A Maintenance Agreement to reference WPO202000016 is
required for on -site filterra unless an executed maintenance agreement with Albemarle Co. exists.
c. Provide bk.-pg. ref. to SWM Facility Easement for District Ave. biofilter*. (Rev. 1) Addressed.
(* This SWM facility easement may be included with Master Declaration referenced in Plat, sheet
1, Note 8, but Certificate of Plat only states that a Master Declaration will be prepared, and does
not provide bk.-pg. ref. to recorded Master Declaration, or to a SWM (biofilter) easement.)
3. C1: Beneath plan title text reading Amendment to WPO2011-00055, please provide new text reading
VSMP IWPO202000016. (Rev. 1) Addressed.
4. below
SDP202000024 Engineering final site plan review comments, 15-Apr 2020
For Final Site Plan Approval: (FSP) Partially addressed /see below.
WPO202000016 review is pending.
Submit VSMP Amendment Plan to WPO2011-00055. Although WPO2011-00055 is approved, site layout
has changed. WW Associates prepared WPO2011-00055 /SDP2011-00047, so plan sheets and design data
are likely readily available. At a minimum, please include the following with WPO Plan Amendment:
a. (LOD) Limits of Disturbance. Ref. SDP C-15, DA Parking Area: Project Area =3.01 Ac. (FSP)
Comment persists. As follow-up, revise WPO C-3 to include label /leader line indicating 2.66 Ac.
disturbance. (Rev. 1) Addressed.
b. Since claiming this is a grandfathered project, ref. /address conditions required for Grandfathering
to guide review and approval, including 9VAC25-870-48.A. L(iv): `...has not been subsequently
modified or amended in a manner resulting in an increase in the amount of phosphorus leaving
each point of discharge, and such that there is no increase in the volume or rate of runoff.' This
means if apartment development runoff exceeds parking lot runoff, then on -site preliminary and
modest detention may be required prior to discharge to overall Albemarle Place detention system
installed beneath Costco parking lot. Design should provide and review will consider: points of
discharge, amount /rates of storm release from D 1, especially whether apartment development
increases overall site imperviousness even slightly, which it appears may be the case. Please ref.
9VAC25-870-48, as well as SDP2011-00047, sheets C-15, -16 (Storm Sewer Design comps), etc.
(FSP) Comment revised to request that WPO202000016 confirm any increase in rate of runoff or
amount of phosphorus leaving SWM detention facility beneath Costco parking lot (easement
shown on bk.-pg. 4135-223). (Rev. 1) Addressed. Applicant response (WW Assoc. letter,
5/21/20): `The North UGD detention system was designed utilizing a 90% impervious cover for
Block D1 based on the ultimate buildout condition. The impervious cover for the proposed
development is 83.4%. Therefore, the rate of discharge from the North UGD system is decreased
with this development. The North UGD Stormfilter and Vortechs units provide a higher
phosphorous removal rate than required. Please note the calculations indicate that the amount of
phosphorous leaving the site has increased slightly from the approved analysis provided with
Engineering Review Comments
Page 3 of 6
WP02011-00055. This is due to the use of the higher re -development removal rate being utilized
on the Simple Method Worksheet versus the new development removal rate that was used for the
construction of the existing parking lot.'
c. Revised storm sewer design computations. Also, see item 7., below. (FSP) Partially addressed.
As follow-up: see item 24, below. (Rev. 1) Persists at SDP2020-00024, Engineering review item
24.
[Item 24: `Storm profile 46 thru 46.8 shows 18" HDPE downstream of 24" DIA pipe. Increase
receiving pipe diameter.' Note: Include storm profiles (not at present included) with WP02011-
00055 Amendment /WP0202000016 since post -developed As -built drawing (relocated filterra)
also needs to include storm lines built with apartment project. Also, SWM Plan item 5, below.]
d. ESC Plan: show tree protection (TP) for trees that are to remain. (FSP) Addressed /shown on
WP0202000016 C-3.
e. SDP2011-00047, C-18 includes typ. ESC measure details required during parking lot construction.
Provide ESC measures appropriate for parking lot demolition, and apartment construction. These
may consist of IP, RWD, TS, SAF, etc. but prior -approved WPO does not consider current
development, only past development. ESC plan is required with WP02011-00055 Amendment.
(FSP) Addressed. WP0202000016 is under review
f. SWPPP: Use county template; please also include: (FSP) Addressed -see WP0202000016 for
follow-up comments.

Grandfathering. A separate Easement Plat Application with fee, as well as separate independent
review of plat, is required. Please ref. county website, Planning documents. Tori Kanellopoulos
may be a helpful resource guide. (FSP) Comment persists. Compare plat at bk.-pg. 4135-221
with SDP202000024 C8 relocated filterra (Bond St.). A SWM facility easement is required for
this relocated filterra. Also: WP0202000016 review comments /comments pending. (Rev. 1)
Comment persists. Applicant: `The multiple filterra units Located within Stonefield at large are
not provided with individual maintenance easements. Maintenance for the facilities are addressed
within sections 7.2.3 and 9.2.2 of the master declaration for Stonefield. A copy of the master
declaration is provided with this submittal as requested by Planning.' Asefollow-up: 18-
32.7.4.2.a.1: `An easement for all stormwater management facilities and drainage control
improvements located on the site shall be established...' Engineering evaluates design against
ordinance requirements.

Additional information from WPO2011-00055, including tables, civil details, ESC legend, SWM
Plan data (Filterra unit/s [relocation /size]; VA SWMH, 1999, Vol. I1, Appendix 5D Worksheets
[revise, as needed; ref. SDP2011-00047, C-23]), including ref. to approved WPOs, to prepare a
comprehensive standalone Amendment to WPO2011-00055. (FSP) Comment persists. For
example: WPO202000016, C7, Stormwater Narrative relies on biofilter `installed as part of the
Stonefield Blvd Road Plan (WPO201100036).' WPO2011-00036 (C-22) shows a biofilter at
present-day Int. of District and Houston. Please provide an As -built drawing comparing as -built
condition of this biofilter against design (WPO201100036, C-22). Note: WPO201100036, C-22,
calculations provide that load removed by biofilter (C-22) = 5.26 X 0.65=3.42lbs. If later WPO or
WPO Amendment revised biofilter design to provide WPO202000016 C7 pollutant removal of
9.69 lb, reference WPO# on SDP202000024 and WPO202000016. Also, please revise
WPO202000016 C7 text /calculations (Narrative), consistent with as -built condition of Houston -
District biofilter, and approved SDP /WPOs, including biofilter landscaping (as -built v. design).
(Rev. 1) Addressed. Applicant: `An analysis of the District Ave. biofilter confirms that it was
constructed in accordance with the Amendment to the Stonefield Blvd Road Plans WP02011-
00036 dated 3/12/12. The surface area of the constructed biofilter is approximately 4,493 sq.ft.
and 4,437 sq.ft. is required. The as -built survey for District Ave. indicates that the biofilter
plantings were installed in accordance with the approved plans. The 3.421b removal rate shown on
the Stonefield Blvd Road Plans WPO2011-00036 was only for the drainage areas directly
associated with the road plans and did not include D1. The BMP calculations for D1 are provided
separately on the CI -IV Final Site Plans WPO2011-00055. The pollutant removal rate used for
the biofilter is 65%'

6. Easement deeds and District Ave. biofilter SWM Facility Maintenance Agreement must be recorded prior
to VSMP /WPO2020-00016 approval. (Rev. 1) Comment persists. Also, item 4.h., above.
D. Erosion and Sediment Control Plan (ESOP)
Virginia Code §62.1-44.15:55 requires the VESCP authority to approve or disapprove an ESOP. This plan
is disapproved for reasons listed at item 3, below. The erosion control plan content requirements can be
found in County Code section 17-402.
1. C2: Provide reference to 2.66 Ac. area of disturbance. Also, item 4.a., above. (Rev. 1) Addressed.
2. CC3: Remove /replace this plan sheet. Provide a Phase 1 ESC plan based upon existing conditions, that
includes demolition. Ex. condition is paved lot. Ref. 3/19/18 Pictometry2 imagery, below. At a minimum,
provide: (Rev. 1) Addressed. Applicant: `The plan sheet showing the paved parking lot has been added
showing the requested information. A stockpile is not anticipated during this phase of construction. Inn
addition, it is anticipated that the safety fence will be temporary chain link fencing and will not be
embedded into the pavement'
a. Existing land cover (pavement).
b. Existing grade: generally flat, since paved.
c. Inlet protection during demolition of existing pavement.
d. Sequence of demolition should a portion of Ex. pavement serve as a stockpile /storage area.
e. Paved construction entrance symbol, PCE, on plan (detail shown on C6). Construction vehicles
may not exit onto Inglewood via a stone construction entrance. Show /label spray wash.
f. PCE spray wash collection /small trapping measure. Also, see PPP Exhibit.
g. ESC measures appropriate to Ex. paved /impervious condition.
h. If safety fence is proposed for paved areas, include detail that specifies embedment of SAF posts.
i. If PCE is gated into the site, show and label gate.
j. * It is vital for incident -free compliance to work from Ex. conditions, to match ESC perimeter
controls to existing conditions /demolition, and to consider staged vertical construction of the
apartment complex.
[ image removed with Rev. 1 comments]
3. C=4: Remove contractor laydown /storage that overlaps improvements at entrance on Houston. An interim -
phase ESC plan may be required to advance site work /vertical construction. Main entrance to apartments
on Houston could serve as laydown /storage while portion of site is developed. At some point, it appears
an offsite laydown /storage area may be required. This off -site area must be identified /reported to CDD
prior to project receiving a grading permit, or sequence demonstration made that an off -site area is not
required even as construction of a building that occupies nearly the entire site advances. Note: The
Standard (Main Street, Charlottesville) required long-term closure of a travel lane of Main St. (Rev. 1)
Persists. Applicant: `The contractor laydown/storage area has been removed as requested. The use of off -
site areas or any temporary lane closures required for the building construction is at the Contractor's
discretion and falls within means and methods. The Contractor shall update the SWPPP as required during
construction to address site conditions as they are revised from that shown on the plans.' As follow-up:
Comment accurately states any off -site areas must be identified /reported to CDD prior to project receiving
a grading permit if an off -site area is known with a degree of certainty prior to preconstruction conference.
A contractor is not at liberty to disturb off -site areas >10,000 sq.ft. absent coordination with Engineering.
A means and methods exemption from VSMP requirements that may apply to an offsite laydown /storage
area within Albemarle County does not exist, per se; only area of disturbance exemptions exist. Contractor
is expected to notify Engineering at any point during construction of any off -site activity that may involve
land disturbance. Please add notes to plan to convey this meaning.
4. Additional comments possible. (Rev. 1) Persists. Additional comments possible

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.
Feview. Video or teleconference is available for review comment discussion; covid-19 pandemic has altered past
practices.
Process:
After approval, plans 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.
Stormwater Management Facilities Maintenance agreements will also have 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 have to be submitted along with court recording fees.
After bonding and agreements are complete, county staff will 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 have 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 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.
County forms can be found on the county website forms center under engineering;
