Dear Mr. Reitelbach:
RE: SDP2021-00056
Airport Road Pump Station Project
Final Site Plan
Review Response Letter
Rivanna Water & Sewer Authority
SEH No. RIVAN 153082 14.00
We received your August 12, 2021 letter with review comments on our final site plan submittal SDP2021-
00056 for the RWSA's Airport Road Pump Station. On behalf of the Rivanna Water & Sewer Authority of
Albemarle County, Virginia, we have prepared this letter in response to your comments. Our letter is
formatted to list your inquiry/comment in regular or bold font followed by our response in italics font.
1. [32.5.2(a)] Identify on the cover sheet that this plan is a "final site plan." Also, provide the
application number on the cover sheet of the plan — SDP2021-00056.
Response: The cover sheet has been updated to reflect that this is a "final site plan". The
application number has been added to the cover sheet
2. [32.5.2(a)] The signature line for the Health Department can be removed from the approval
box on the cover sheet. This site is within the jurisdictional area of the Albemarle County
Service Authority (ACSA).
Response: Virginia Department of Health has been removed from the approval box on the
coversheet.
3. [32.5.2(a)] On the cover sheet, provide an address for the property owner.
Response: The address for the property owner has been added to the cover sheet.
4. [32.5.2(b)] Clarify why the proposed impervious area identified on the cover sheet is less than
the sum of the building footprint, generator enclosure, and paved parking/vehicular circulation
area.
Response: This is a typo and has been updated on the cover sheet.
5. [32.5.2(c)] As it appears that the ground storage tanks are to be built at a later time, either

remove them from this plan, or provide phase lines/information on the plan identifying the
limits of the future phase(s).
Response: The dashed lines depicting the anticipated location of the future tanks have been
removed from the plan sheets and replaced with the following note "SPACE FOR
ANTICIPATED FUTURE GROUND STORAGE TANKS".
6. [32.5.2(i)] Provide the state route number for Berkmar Drive on the site plan layout sheet
(sheet C09).
Response: The state route number for Berkmar Drive has been added to Sheet C09.
[32.5.20); 32.5.2(k)] An easement plat will be required for all stormwater management facility,
drainage, and access easements. This easement plat will need to be reviewed, approved, and
recorded prior to the approval of the final site plan.
8. [32.5.2(n); 4.17] Outdoor lighting.
a. The light loss factor (LLF) on the photometric plan (sheet DE1) must be 1.00. Revise
the luminaire schedule with an LLF of 1.00.
Response: Sheet DE1 has been revised and updated with a light loss factor of 1.00.
b. Revise the photometric plan calculations to reflect an LLF of 1.00.
Response: Sheet DE1 has been revised and updated with a light loss factor of 1.00.
9. [32.5.2(p); 32.7.9] Landscape plan.
a. The Conservation Plan checklist on the landscaping plan sheet will need to be completed,
signed, and dated by the property owner prior to approval of the final site plan.
Response: The landscaping plan has been signed and dated by the property owner.
b. It is suggested that the label for the proposed undisturbed buffer along the southwestern
property line be revised to separate the 20' undisturbed buffer at the rear of the property from
a "variable width" undisturbed buffer closer to the proposed Berkmar Drive right-of-way, to
accommodate the proposed clearing and replanting that will occur in that area.
Response: The "20.0' UNDISTURBED LANDSCAPE BUFFER" was kept on the plans.
This gives the onsite representative of the Owner and Engineer more control in minimizing
tree removal.
c. In the landscaping schedule, provide the number of Virginia Pines that are proposed to be
planted. In addition, provide the caliper of the proposed trees, and the expected height of
the trees at ten years maturity after planting.
Response: The landscaping schedule has been updated to reflect this information.
The original comments from the review and action letter for SDP2020-00060 are in gray font. Follow-
up comments from the review of the final site plan, SDP2021-0056, are in bolded black font. Please
address these follow-up comments as well.

1. [32.5.2(b)] Include the generator and its enclosures in the list of proposed uses on the cover
sheet of the plan
Also, provide the square footage and height of the generator enclosure on the cover sheet and
on the layout plan. Clarify the structure that is enclosing the generator and portable
pump. Are they enclosed within the building, or is a fence surrounding these elements?
Response: The generator has been added to a list of uses on the cover sheet. The generator
is covered by an extension of the pump station roof, so the height is the same as the building.
There are no walls or fence surrounding the generator, it is open on all sides. A fence will be
provided around the perimeter of the site.
2. [32.5.2(b); 4.12.7] As the proposed use is an unscheduled use in regard to the Parking
requirements, Section 4.12, submit a letter to the Zoning Administrator with a request for the
proposed number of parking spaces. This request must include justification for why the
proposed number of parking spaces is expected to provide sufficient parking capacity for the
proposed use. The number of parking spaces required for this use will ultimately be
determined by the Zoning Administrator. This comment has not been addressed. Submit
a letter addressed to the Zoning Administrator with justification for the proposed
number of parking spaces to be provided. The ultimate determination on the
required number of parking spaces will be made by the Zoning Administrator.
Response: A letter has been prepared and submitted to the Zoning Administrator for this
determination. This letter has also been enclosed following this response letter.
3. [32.5.20); 32.5.2(1)] Identify all existing sewer and drainage facilities, as well as all existing
and proposed utilities.
a. An approved easement plat will be needed for the proposed utilities and stormwater
facilities. Once recorded, the deed book and page number(s) for the new easements
will need to be noted on the plan before final approval can be granted.
This comment must still be addressed.
Response: An easement plat will be prepared for the stormwater facilities once the
County has approved of the proposed design.
4. [32.5.2(k)] Proposed sewer and drainage facilities. Depict these facilities and their
dimensions. If necessary, an approved and recorded easement plat will be required prior to
approval of a final site plan and/or final subdivision plat. (This comment and the comment
above are standard comments for all site plans, and staff recognizes that they may not apply
to this project in the same way as most other projects since this site plan is for an RWSA
facility.) This comment must still be addressed.
Response: There is no sewer associated with the project. Stormwater facilities have been
updated as per conversations with J. Anderson.
5. [4.1] Provide a note on the cover sheet identifying whether this property is located within the
ACSA jurisdictional area. This comment has not been addressed.
Response: This comment has been addressed.
Albemarle County Architectural Review Board (ARB) - Khris Taggart, ktaggart(aalbemarle.org
1. No details have been provided on the appearance of the ground storage tanks. If the ground storage

tanks are proposed with this submittal, provide details on the architectural designs of the ground
storage tanks, including a color sample. If details on the appearance of the ground storage tanks
are unavailable at this stage, revise the site plan to remove all references to the ground storage
tanks.
Response: As per email correspondence with K. Taggart, the dashed lines depicting the
anticipated locations of future tanks have been removed from the plan sheets and replaced with
the following note "SPACE FOR ANTICIPATED FUTURE GROUND STORAGE TANKS'.
See comment #1 regarding notes/references to ground storage tanks. If details on the appearance
of the ground storage tanks are unavailable at this stage, revise the site plan to remove all
references to the ground storage tanks.
Response: As per email correspondence with K. Taggart, the dashed lines depicting the
anticipated locations of future tanks have been removed from the plan sheets and replaced with
the following note "SPACE FOR ANTICIPATED FUTURE GROUND STORAGE TANKS'.
3. The standard mechanical equipment note is not included in the site plan. Revise the plan to include
the standard mechanical equipment note: " Visibility of all mechanical equipment from the Entrance
Corridor shall be eliminated."
Response: This note has been added to Sheet A200
4. The LLF of the proposed fixtures is less than 1.0. Revise the photometric plan using an LLF of 1.0
for all fixtures.
Response: Sheet DE1 has been revised and updated with a light loss factor of 1.00.
No details on the view of the ground storage tanks from Airport Rd. have been provided. If the
ground storage tanks are to be proposed and reviewed with this submittal, provide site sections that
show the view of the site, including the storage tanks from the Airport Rd. frontage.
Response: As per email correspondence with K. Taggart, the dashed lines depicting the
anticipated locations of future tanks have been removed from the plan sheets and replaced with
the following note "SPACE FOR ANTICIPATED FUTURE GROUND STORAGE TANKS..
Albemarle County Engineering Services (Engineer) - John Anderson, ianderson2(c@albemarle.org
Requested changes; see the attached checklist and comment memo.
Response: Responses to the comment memo are below:
1. Recommend revise plan title to include ref. to SDP202100056.
Response: This has been added to the title sheet.
2. Revise T01 to include reference to related plan, WPO202100035.
Response: This reference has been added.
3. Revise sheet list, T01, to remove ESC-SWM-PPP (WPO plan -related) sheets from the final site
plan.
Response: The sheet list and the sheets included in the resubmittal have been updated to
address this comment.
4. Revise T01 topography note to confirm existing topography has been at least visually verified
within the last 12 months [See Final Site Plan checklist for plan reviewers, p. 1, Existing
conditions plan view information; 2nd item —ref. attached].
SDP2021-00056
Airport Road Pump Station — Final Site Plan
Review Comments Letter
Page 5
Response: This note has been added.
5. Coordinate final site plan design with VDOT. VDOT has near -term plans to extend Berkmar Drive
Ext. to Airport Drive. Ensure that the final site plan proposed grade (final contours) are consistent
with roadway extension. At present, they are not. Proposed grade suggests relatively abrupt rise
into the site, with gradual fall, west to east, across the site. Ref. sheet C12, Grading Plan. If grade
is to be flatter, consistent with future Berkmar Drive Ext. roadway, then grades must be lowered
across the site. Retaining walls may be required between proposed development and parcel to
immediate north in order to eliminate 4'-5' grade rise at entrance to RWSA pump station.
Retaining walls are a common remedy for addressing grade issues. Retaining wall ht. > 4-ft.
requires a sealed geotechnical retaining wall design. Please coordinate directly with VDOT on
Berkmar Drive Ext. (future) design, and accommodate reasonably -predictable VDOT Berkmar
Drive Ext. future design needs.
Note: Virtually all sheets of the FSP show and label Anticipated VDOT Grading Easement (Typ.),
yet the FSP proposes grades that conflict with Berkmar Drive Ext. future grading. Please revise
FSP consistent with anticipated VDOT Grading Easement.
Response: We are aware of the future extension of Berkmar Drive. The Owner and Engineer
have coordinated with VDOT to the best extent possible. The plans for the permanent site
access drive have been coordinated with preliminary drawings in an effort to minimize future
conflicts.
Please remove sheet C09 bioretention basin specific design elements (footprint with label is fine),
as well as sheets C10, C11, C13, C16, DC03 from the site plan since ESC measures and SWM
facilities are not approved with a site plan, but with a WPO plan. WPO plan review is pending
(WPO202100035).
Response: These sheets have been removed from the set and the Sheet List on T01 has been
updated.
C12: Provide final disposition of runoff along south side of site access; specifically: provide
channel lining design and velocity/capacity calculations for runoff in ditch -line between contours
623 and 615. Proposed grade routes runoff to a bend in site access, at which point runoff
appears to sheet across site access without routing to any SWM capture or conveyance system.
Include a new Drainage Plan sheet that shows storm runoff collection and conveyance.
Response: Stormwater facilities have been updated as per conversations with J. Anderson and
are shown in the resubmitta/ of the WPO plan.
8. With WPO Plan, account specifically for increased sheet flow from impervious parking and site
access (reasonably anticipated to occur) along south side of development, given close proximity
to property line.
Response: Stormwater facilities have been updated as per conversations with J. Anderson and
are shown in the resubmittal of the WPO plan.
9. C15: Engineering defers to Planning Division as to whether proposed grading within 20.0'
undisturbed landscape buffer qualifies as undisturbed. C08, Existing Conditions, accurately
describes existing condition as 'existing wooded area mix of deciduous and evergreen trees.' The
site is 100% mature canopy mix. If mature mix of deciduous and evergreen trees is removed,
replacements will not attain maturity for decades. Engineering defers to Planning, but if site grade
is lowered, generally, it may be not only feasible but relatively easy to preserve 20.0' undisturbed
landscape buffers along parcel boundaries, for the entire development. Engineering encourages

design to preserve an undisturbed landscape buffer to the maximum extent practical. Retaining
walls may aid in addressing this and other review comments.
Response: This was not noted in the comments from the Planning Division. The minor grading
and replanting in the 20-foot buffer was designed in an effort to maintain as much of the mature
canopy as possible and is believed to be preferable to planting vegetative screening through a
double staggered row of evergreen trees planted 15-feet on center, as described in 32.7.9.7.e.

RE: SDP 2021-00056
Request for Parking Space Review
Airport Road Pump Station Project
Rivanna Water & Sewer Authority
SEH No. RIVAN 153082 14.00
The Rivanna Water & Sewer Authority (RWSA) has proposed to construct the Airport Road Pump
Station (ARPS) at TMP 32-41A2, generally located at the northern terminus of Berkmar Drive. The
County's site plan review process, SDP 2021-00056, has identified that the proposed use of the site
is an unscheduled use in regard to the parking requirements. This letter is being submitted on behalf
of the RWSA to request a review and approval of the proposed number of parking spaces, four (4),
at the proposed Airport Road Pump Station.
Background
The ARPS is a proposed potable water booster station which will serve to improve the RWSA
operations of the potable water distribution system. The proposed ARPS consists of a 1,209 square
foot building of cavity wall masonry construction and an adjacent 769 square foot covered generator
pad. The proposed ARPS will be an unmanned pump station and will receive periodic visits by RWSA
staff. The site and pump station are not public facilities and the entire site is fenced to prevent access
to the site.
Selected sheets from the site plan submittal are enclosed for your reference.
Design efforts have planned for four (4) dedicated parking spaces to be provided at the site to allow
for parking during occasional visits by RWSA staff. Due to the unmanned nature of the pump station,
it is proposed that four (4) dedicated parking spaces is sufficient for the intended use of the site.
Closure
We trust that this letter is sufficient to complete your review. If you wish to discuss the project or have any
additional questions, please do not hesitate to contact me by phone at 507.440.7485 or
bweiss@sehinc.com.
