Proposal
To renovate an existing building supply store and warehouse into an auto dealership showroom with sales, parts and service
offices and auto repair space.
Context
This parcel extends from Rt. 29 at the east to Berkmar Drive at the west, in a heavily developed commercial corridor.
Automobile dealerships with vehicle display are located nearby at the Jim Price and Brown sites a short distance north on Rt.
29. The Carrsbrook neighborhood is located across Rt. 29 to the east.
Visibility
The main building on site is readily visible from the EC. The metal buildings located behind the main building are also visible
from the EC, but they have less impact due to their position behind the main building and the increased distance from the
road. Each of the proposed vehicle display/storage areas will be visible from the EC, with the display area at the front having
the most visual impact on the EC.

SITE/PROJECT HISTORY
The ARB completed a review of the request for a Special Use Permit to establish outdoor sales, storage and display at this site on June 6, 2016. The
action letter from that meeting is included as Attachment A to this report. Among the recommendations made at that time were the following: "Note that
standard trademark/branding elements may require modification to meet the EC Guidelines."
PROPOSAL
The applicant's proposal to establish an automobile dealership at this site includes the renovation of the building supply store into an automobile
showroom and the construction of an addition at the south end of the building for service drop-off. Buildings behind the showroom would be renovated
to accommodate parts, service, vehicle prep and body shop functions. The current application focuses on the design of the renovation of the showroom
and the new service drop-off addition.
CHANGES TO THE PLAN SINCE THE LAST REVIEW
1. The applicant has decided to build the service drop-off building at the south side of the showroom.
2. The existing structure located closest to the body shop is proposed to be removed to provide space for parking vehicles awaiting repair in the body
shop.
3. Screening trees and shrubs are shown around the existing stormwater facility to help limit visibility of parked cars at the rear of the site.
4. The vehicle prep building located at the middle of the site is to be removed.
5. Four trees are proposed to be added in islands along the east end of the south side of the middle vehicle storage area.
6. The proposed arrangement of parking spaces in the front display area has been delineated on the plan. Tree locations in the parking area have been
revised.
7. Trees along the front of the building have been deleted from the proposal.

Visitors to the significant historical sites in the
Charlottesville and Albemarle area experience these
sites as ensembles of buildings, land, and vegetation. In
order to accomplish the integration of buildings, land,
and vegetation characteristic of these sites, the
Guidelines require attention to four primary factors:
compatibility with significant historic sites in the area;
the character of the Entrance Corridor; site development
and layout; and landscaping.
Structure design
New structures and substantial additions to existing
structures should respect the traditions of the
architecture of historically significant buildings in the
Charlottesville and Albemarle area. Photographs of
historic buildings in the area, as well as drawings of
architectural features, which provide important
examples of this tradition are contained in Appendix A.
The examples contained in Appendix A should be used
as a guide for building design: the standard of
compatibility with the area's historic structures is not
intended to impose a rigid design solution for new
development. Replication of the design of the important
historic sites in the area is neither intended nor desired.
The Guideline's standard of compatibility can be met
through building scale, materials, and forms which may
be embodied in architecture which is contemporary as
well as traditional. The Guidelines allow individuality in
design to accommodate varying tastes as well as special
functional requirements.
It is also an important objective of the Guidelines to
establish a pattern of compatible architectural
characteristics throughout the Entrance Corridor in order
to achieve unity and coherence. Building designs should
demonstrate sensitivity to other nearby structures within
the Entrance Corridor. Where a designated corridor is
substantially developed, these Guidelines require
striking a careful balance between harmonizing new
development with the existing character of the corridor
Many of the buildings in the immediate vicinity of this
site predate the establishment of the EC. They include
the Better Living furniture store, Schewel's Furniture
store and Kegler's to the south, and the original Jim
Price auto dealership to the north. Nearby buildings
that have undergone ARB review include: the Jim
Price renovation, Wal-Mart and Brown auto to the
north, Rivanna Plaza to the south, and Northtown
Center (Gander Mountain) to the southeast.
The proposed showroom design has some similarity to
the Price and Brown auto dealerships. Metal panels
are used at the Price site and both the Price and Brown
buildings, like the proposed Malloy design, use the
typical auto dealership form of substantial sign band
at the top, large storefront windows separated by
coordinating piers, and a monumental entrance
feature.

integrate it more fully
into the overall design.
Four metal panels are identified on the elevation
drawings: 1) a decorative metal panel in bright silver
with a brushed finish (Alpolic hairline aluminum), 2)
a metal panel in a darker "mica" gray (Alpolic mica
finish), 3) a corrugated metal panel in slate grey
(Alcoa), and 4) a ribbed metal panel in slate grey
(Alcoa).
Alpolic describes the decorative metal finish (1) as
follows: "Alpolic decorative metal panels feature
specially treated aluminum finishes on the outer skin
of the panel, protected by a clear top coat. HLZ has a
mechanically brushed surface that resembles brushed
stainless steel.... But instead of applying a pigmented
finish to the top skin, we ... apply a hairline brush
treatment (HLZ) for more diffuse reflectivity, similar
to brushed stainless steel. We then add a top coat .....
to ensure these aluminum finishes maintain their
pristine look for decades, even in harsh exterior
applications."
The Alpolic website describes the mica finish (2) as
follows: "With embedded mica, panel colors take on a
pearlescent warmth with a subtly dimensional
appearance. It's a look that catches the light, the eye
and the imagination... The mica catches and reflects
light in a dynamic way that can vary from muted to
brilliant depending on the brightness of the light and
angle of the viewer."
The Alpolic panels have reflective finishes. Highly
reflective metal panels would not be appropriate for
the EC. Light Reflectance Value (LRV) and Solar
Reflectance Index (SRI) are two measures of
reflectivity. These measurements are not consistently
available for each of the proposed materials. The
information that is available is provided in Attachment
B. Staff's visual comparison of the proposed metal
panels and samples of previously approved metal
panels (for other EC proposals) in sunlight showed the
decorative metal panel (1) to be highly reflective
when the sun shines directly on it. Given the location
of the building, this is likely to happen in the morning
hours. This level of reflectivity would not have an
appropriate appearance for the EC. The darker gray
mica panel (2) was much less reflective and is
expected to have less negative impact. The amount of
reflectivity of each of the panels is expected to change
as the sunlight changes throughout the day. Larger
samples might provide a better approximation of the
proposed appearance.
The ribbed and corrugated panel surfaces are less
reflective than the others, but they have wide ribs and
a utilitarian appearance and look like the standard
metal siding typically used for industrial warehouses
and smaller scale sheds. The utilitarian character
appears out of place with the other proposed finishes
and it is not appropriate for applications in close
proximity to the EC. A more refined finish with more
texture than the smooth panels would be appropriate.
A reduction in the amount of the hairline aluminum
panel (1) and use of the panels in conjunction with a
traditional masonry material would be appropriate for
the EC.
The extensive use of metal in this proposal
emphasizes the modern character of the design.
Although metal has been used historically in building
construction, the manner and character of its use here
emphasize the modern. The material, color, texture,
and reflective finish all emphasize modern design
rather than the historic character of the County.
PPG paint in color "thin ice" is proposed for the
service building behind the showroom. The color is
nearly white. A darker shade would help de-
emphasize the service buildings.

(The following information on LRV and SRI is taken from various on-line resources.)
Light Reflectance Value (LRV) is a measure of the amount of visible and usable light that reflects from a painted surface. LRV measures the percentage
of light a paint color reflects. The measurement scale ranges from zero (absolute black, absorbing all light and heat) to 100 percent (pure white, reflecting
all light.
0% 10% 20°%0 30% 40% 50% 60% 70% 80% 90% 100%
The Solar Reflectance Index (SRI) is a measure of a constructed surface's ability to reflect solar heat, as shown by a small temperature rise. It is defined
so that a standard black surface (reflectance 0.05, emittance 0.90) is 0 and a standard white surface (reflectance 0.80, emittance 0.90) is 100. It is used for
compliance with LEED requirements. (Solar reflectance determines the fraction of the solar radiation incident from all directions that is diffusely
reflected by the surface. Thermal emittance describes how well the surface radiates energy away from itself as compared with a blackbody operating at
the same temperature.)
