Review Type

Proposal
To construct a Granular Activated Carbon facility at the Crozet Water Treatment Plant, including a pre- engineered
metal building.
Context
The immediate area has an industrial character. The surrounding area is a mix of rural character and suburban
residential development.
Visibility
The proposed building will be readily visible from the Entrance Corridor, but the narrow width of the road, the curve
of the road, and the trees on nearby properties limit visibility to an approximate 500' length of the corridor directly in
front of the property.

CHANGES TO THE PROJECT SINCE THE LAST REVIEW
The loading dock has been moved from the north side to the south side of the building.
The travelways have been modified. The amount of gravel roadway has been reduced.
More existing trees are being saved. New trees and shrubs are proposed.
Piping has been revised for less impact on existing trees to remain.
The landscape plan has been revised to include recommendations from a certified arborist regarding the treatment of trees to remain that
are located near proposed construction.

SUMMARY OF RECOMMENDATIONS
Staff recommends the following as the primary points of discussion:
1. Revised travelway layout
2. Revised building design: color choices, distribution of colors
3. Revised landscaping
Staff recommends approval of the plan with the following conditions:
1. Choose an alternate wall pack that meets the county's definition of "full cutoff'. (Look for a fixture with no vertical glass below the
metal housing.)
2. Indicate the fixture color in the luminaire schedule.
3. Add the standard lighting note to the plan: "Each outdoor luminaire equipped with a lamp that emits 3,000 or more initial lumens shall
be a full cutoff luminaire and shall be arranged or shielded to reflect light away from adjoining residential districts and away from
adjacent roads. The spillover of lighting from luminaires onto public roads and property in residential or rural areas zoning districts shall
not exceed one half footcandle."
4. Revise note 3 on Sheet LO to clearly state that an arborist will be present on site when trenching occurs.
5. In the notes on Sheet LO 1, revise all "will" to "shall ".
6. Check the boxes in the conservation checklist that apply to the proposed work.

RE: ARB- 2013 -103: GAC Upgrade for Crozet Water Treatment Plant
Dear Ms. Hennessy,
The Albemarle County Architectural Review Board, at its meeting on September 16, 2013, completed a preliminary review of the above -noted request to
construct a Granular Activated Carbon facility at the Crozet Water Treatment Plant, including a pre- engineered metal building. The Board offered the
following comments for the benefit of the applicant's next submittal. Please note that the following comments are those that have been identified at this
time. Additional comments may be added or eliminated based on further review and changes to the plan.
1. Consider alternate travelway layouts and building locations and /or orientations to reduce visual impacts and overall area of paving /gravel drive
visible from the EC, and to increase landscape opportunities along the EC.
2. Identify for review, and on the plan, the color of the metal panels for the walls and roof. The wall and roof color shall be compatible with the
primary color of the existing water treatment plant.
3. Consider the guidelines under "Structure Design" items 9 -19. The next submittal shall describe how these items have been addressed.
4. Revise the plan to include the new location of the existing shed. Consider moving the shed to a less visible location than the current one.
5. Provide a fence detail in the plan. Indicate fence material, height, and design. The black finish is more appropriate for the EC. Revise the fence
location so that it does not cross in front of the proposed building.
6. Clarify which new equipment, if any, will be visible from Rt. 240.
10
7. Confirm that no new site or building lighting is proposed, or show the proposed lighting on the plan and provide all related details.
8. Add tall shrubs among the group of trees identified as to remain in the area north of the GAC facility. Ensure that the shrubs are planted in a
natural, informal pattern and that they provide low level screening for the site.
9. Clarify the level of tree /shrub removal proposed for installation of bio- retention area #2. Add new plants to achieve a natural, informal
appearance along the EC.
10. Provide a plant schedule in the site plan with all standard information.
11. Add the following note to the site plan: "All site plantings of trees and shrubs shall be allowed to reach, and be maintained at, mature height; the
topping of trees is prohibited. Shrubs and trees shall be pruned minimally and only to support the overall health of the plant."
12. Provide verification from a certified arborist that the proposed fill, grading, and digging required to install the piping and other site work will not be
detrimental to the health of the trees designated to remain. Provide an arborist's plan outlining measures to ensure the health of the trees
throughout and after the work. Include the arborist's measures on the site plan drawings.
13. Identify on the plan the size and species of the trees to remain in the area at the middle of the gravel drive and in the area west of the driveway
along the EC.
14. Provide a tree conservation plan and checklist. Provide tree protection in the areas impacted by the construction of bio- retention area #2.
You may submit your application for continued ARB review at your earliest convenience. Application forms, checklists and schedules are available on -line
at www.albemarle.org /ARB.
Revised drawings addressing the comments listed above are required. Include updated ARB revision dates on each drawing. Please provide a memo
including detailed responses indicating how each comment has been addressed. If changes other than those requested have been made, identify those
changes in the memo also. Highlighting the changes in the drawing with "clouding" or by other means will facilitate review and approval.
If you have any questions concerning any of the above, please feel free to call me.
