Subject: SDP2021-00056 — Airport Road Pump Station — Final Site Plan; 11 Review Final Comments
The Planner for the Planning Services Division of the Albemarle County Department of Community Development will
recommend approval of the plan referred to above when the following items have been satisfactorily addressed. (The
following comments are those that have been identified at this time. Additional comments or conditions may be added
or eliminated based on further review.) [Each comment is preceded by the applicable reference to the Albemarle County
Code.]
New Comments — First Review of Airport Road Puma Station Final Site Plan (SDP2021-00056):
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.
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).
3. [32.5.2(a)] On the cover sheet, provide an address for the property owner.
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.
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).
6. [32.5.2(i)] Provide the state route number for Berkmar Drive on the site plan layout sheet (sheet C09).
7. [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 DEl) must be 1.00. Revise the luminaire
schedule with an LLF of 1.00.
b. Revise the photometric plan calculations to reflect an LLF 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.
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.
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.
Comments from SDP2020-00060 — Airport Road Puma Station Initial Site Plan Action Letter:
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 enclosure 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?
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.
3. [32.5.2(j); 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.
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.
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.

Comments from Other Reviewing Departments, Divisions, and Agencies
Albemarle County Architectural Review Board (ARB)
Khris Taggart, ktaaeartCc�r�,albemarle.org — Requested changes; see the comments below
I have reviewed the plans with the revision date of June 04, 2021 submitted for the ARB2021-68 Airport Rd. Pump Station
Final Site Plan. The changes made in these plans do not address all the conditions of approval outlined at the ARB meeting
held on October 5, 2020. The following revisions are requested to make the proposal consistent with the Entrance Corridor
Guidelines (note the numbers below refer to original conditions from the action letter dated October 7, 2020):
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.
2. 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.
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."
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.
7. 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.

1. Recommend revise plan title to include ref. to SDP202100056.
2. Revise TO to include reference to related plan, WPO202100035.
3. Revise sheet list, TO I, to remove ESC-SWM-PPP (WPO plan -related) sheets from the final site plan.
4. Revise TO topography note to confirm existing topography has been at least visually verified within the
last 12 months [See Final Site Plan checklist forplan reviewers, p. 1, Existing conditions plan view
information, 2nd item —ref. attached].
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 C 12 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
ESP proposes grades that conflict with Berkmar Drive Ext. future grading. Please revise ESP consistent
with anticipated VDOT Grading Easement.
6. 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).
7. C 12: 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.
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.
Engineering Review Comments

9. C 15: 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.

Final Site Plan checklist for plan reviewers
17 Feb 2014 (Use the latest checklist from the Team Services engineering forms site)
A site plan is a zoning document, required according to the Zoning Ordinance, Code Chapter 18 section 32 that
delineates the overall scheme of development of one or more lots.
Reference key;
[Square Brackets] are County Code references, {Curved Brackets} are policy references, and (regular
parenthesis) are explanatory. Links to reference documents are provided where possible.
Title information and overall content:
Project title. Titles should be appropriate. It should be a final site plan, not a stormwater
plan, or erosion control plan, a road plan, etc.
Professional seal, with original signature and date. [18-32.6.1]
Content: The site plan must not contain the erosion control plan, stormwater management
plan, road/street plans, or mitigation plan. These must be separate documents, to be
reviewed and bonded separately, and not part of zoning documents or zoning
enforcement, or zoning letters of revision, or permanent land records, etc. If these are
included, they must be removed.
Existing conditions plan view information: (applicable to any type of plan)
accurate current existing topography at the time of submittal, including all existing site
features, and any recent disturbances, all at a legible scale [18-32.6.2]
date and source of the topographic information: [ 18-32.6.2] All topography should be at
least visually field verified by the designer within the last year {see road plan note}
WPO buffer limits; 100' from stream or wetland bank, 200' from reservoirs, or
floodplain limit if greater [17-317]
floodplain limits, including 100yr flood limits for any channel with a drainage area of
50+acres [18-32.6.2d, 18-30.3]

Grading: [18-32.6.2, 14-303]
proposed topography at minimum 2' contour intervals — tied into existing contours, as
well as all proposed site features. (Sites with less than 6' of grade change should consider
using smaller contour intervals.)
proposed slopes are all 2:1 (horizontal: vertical) or flatter {Design Manual, section 81
proposed slopes steeper than 3:1 have low maintenance (not grass) ground cover
specified on the plan {Design Manual, Section 81
existing critical slopes are not disturbed, unless a waiver or exemption has been granted
for the disturbance. [18-4.2, 14-304]
Retaining walls should be accurately shown on plans, reflecting material thickness and
batter where such measurements may affect layout.
Retaining Wall Plans checklist. Any walls supporting roads or necessary infrastructure
require engineered plans (not generic manufacturer's details) and computations. {Design

Manual, section 8) This will also be required where walls are close to property lines and
there is the danger of affecting neighboring property, either during construction, with
later failures, or with pedestrian or vehicle safety. These concerns can be alleviate with
layout spacing also. In any case, retaining walls will require building permits at
construction.
