Zoned Neighborhood Model District (NMD)/Entrance Corridor (EC)/Airport Impact Area (AIA) Owner/Applicant CKW 2 LLC/Roudabush, Gale & Associates (Riki Van-Niekerk) and BMC Holdings Group (Reid Murphy) Magisterial District Jack Jouett Proposal To develop a previously -undeveloped 1.05-acre parcel with a 6,775 sf office building and associated improvements. Context and Visibility The parcel lies on the west side of Hydraulic Road, an EC. The surrounding area is primarily multi -family housing and a few commercial buildings (the parcel to the southwest is undeveloped and zoned RA; the parcel to the northwest is zoned R6 and features townhomes; the parcel to the north is C1 and holds a small commercial building; the parcels to the east, across Hydraulic Road, are zoned R15, C1, and R2; and the parcels to the south are zoned PRD) [Figure 1]. Visibility from Hydraulic Road will be clear.

The total square footage of the building was 6,775 square feet while 51 parking spaces were provided on 14,099 square feet of total impervious coverage. Some 24,908 square feet (or 54%) was dedicated to open space. One significant difference between the current plan and that reviewed in 2008 is the amount of parking: this proposal includes 58 parking spaces, 22 of which are provided as structured parking beneath the building.

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 portion of the Hydraulic roadbed adjacent to this proposed development inclines from 612 feet at the north end to 616 feet elevation at the intersection with Georgetown Road, suggesting that the building will sit slightly above grade, perhaps on an elevated base. 16 Window glass in the Entrance Corridors should not be The window glass note has not been Provide the standard window highly tinted or highly reflective.

Four columnar ginkgo bilobas are also proposed at 1.25" caliper. Furthermore, previous review comments in 2008 requested that the ginkgoes be male species only; a note should be added to the landscape plan that no female ginkgoes will be planted. 33 Landscaping along interior roads: The interior travelway is merely a parking lot None. a.

However, at least 2 of these trees are located atop a 13 proposed sanitary sewer line and an additional 3 trees are located within 2-5' o.c. from the underground utility. As stated previously, it is standard County Engineering staff policy that large shade trees be located a minimum of 7-8' from underground utilities lest there be a conflict. This can be resolved by relocating the proposed sanitary sewer line eastward. 36 Landscaping of buildings and other structures: Landscaping has been provided on the None. a.

Rectify errors in the plant schedule on Sheet 5. The number of Buxus x Glencoe proposed (95) exceeds one -quarter of the total number of shrubs (130) proposed. It is standard policy to request that no one tree or shrub species exceed 25% of the total number of trees or shrubs on the site in order to avoid a 14 monoculture that could be prone to disease. Diversity can only be achieved with the addition of two or more evergreen shrub species to reduce the numbers of Buxus x Glencoe below the 25% threshold, which is 33 plants. Errors exist in the plant schedule that must be corrected: 7 AR and 3 LS are shown on the landscape plan, not 5 as noted for both. 38 Plant health: The note has been provided on Sheet 5. None. The following note should be added to the landscape 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.

These site elements must be shown on the site plan. In regard to parking, as per NMD standards, the parking has been relegated behind the building and structured parking beneath the building is proposed. However, this plan differs from previously approved plans in that it shows double -stacked parking through the full depth of the building footprint. This may not be permissible for this use (office); a determination will be made through the SRC process, and the determination may result in the reconfiguration of the site plan and perhaps may alter present plans for the building design. The building mass is oriented parallel to the EC. Provisions have been made to connect both pedestrian and vehicular systems. Open space has been provided in the western third of the site, while a plaza is proposed on the eastern side of the building as a public amenity. No significant natural features or vistas worthy of preservation exist on this site. 16 Figure 6: Conceptplan as shown in application for ZMA-2016-14.

Similarly, a single row of Arborvitae is proposed for the north side of the southernmost wall; this will not serve to screen the wall from northbound traffic on the EC, and the 20' ACSA easement spanning the southern edge of the property appears to have no extant trees to be retained, and no trees are proposed. Additional vegetation may be needed to mitigate the visibility of these walls. Additionally, details of the proposed retaining walls must be provided in the site plan set, as well as materials and colors for review. 41 No grading, trenching, or tunneling should occur within the The Existing Conditions and Demolition Provide sufficient tree drip line of any trees or other existing features designated Plan sheet (Sheet 2) of the site plan set protection fencing around those for preservation in the final Certificate of Appropriateness. shows dozens of extant trees on the parcel trees to be preserved and clearly Adequate tree protection fencing should be shown on, and with an arrow pointing to two trees in the differentiate between trees to be coordinated throughout, the grading, landscaping and center and a note which states "existing trees removed and those to be erosion and sediment control plans. to be removed." It is therefore unclear how many trees are being removed and which (if retained on Sheet 2 of the site plan set. 42 Areas designated for preservation in the final Certificate of Appropriateness should be clearly delineated and any) are being preserved.

The potential visibility of the retaining walls in the southwest and northwest corners of the site and whether additional landscaping will be required. 2. Whether sufficient landscape area has been provided on the east side of the building to ensure that large shade trees will not conflict with utilities and their easements. Staff recommends that the ARB forward the following recommendations to the Agent for the Site Review Committee: • Regarding requirements to satisfy the design guidelines as per § 18-30.6.4c(2), (3) and (5) and recommended conditions of initial plan approval: 1. Prior to Initial Plan approval, the following items shall be resolved to the satisfaction of the ARB: None. Note that a Certificate of Appropriateness is required prior to final site plan approval. Regarding recommendations on the plan as it relates to the guidelines: None. • Regarding conditions to be satisfied prior to issuance of a grading permit: 1. Provide sufficient tree protection fencing around those trees to be preserved and clearly differentiate between trees to be removed and those to be retained on Sheet 2 of the site plan set. Regarding the final site plan submittal: 1. Architecture and landscaping will be reviewed with a future submittal. A Certificate of Appropriateness is required prior to final site plan approval. 2. Submit material and color samples, dimensioned elevations, and floor plans of the apartment buildings for review. 3. Provide the standard window glass note to the architectural drawings: Window glass in the Entrance Corridors should meet the following criteria: Visible light transmittance (VLT) shall not drop below 40% Visible light reflectance (VLR) shall not exceed 30%. 4. If a refuse area is proposed, show it on the site plan and include details of the dumpster enclosure in the site plan. 5.
