(See Attachment A for the action letter) 11/20/17 ARB-2017-112 ARB will review the final site plan for Block 1. A number of houses and the apartment building have been constructed and some landscaping is in place. CHANGES TO THE PLAN SINCE THE LAST REVIEW At the September 5, 2017 meeting, the Board addressed aspects of the proposed architectural design as well as the site plans. The subsequent revisions to the architectural design of the three proposed buildings’ envelopes are minor and largely concern fenestration and entrances. Single doors on the first floor of the east and west elevations have been changed to double doors. Single doors on the north elevation, first floor, have been moved from the six-light curtain walls to the corners of the building. On the second and third floor balconies of the east, west, and north elevations, two fixed lights and a narrow swing door have been replaced with three equal-sized sliding (pocket) glazed doors. Large C-Channel canopies have been added to the east and west elevations that wrap around the corner doors on the north elevation and are visible in profile from the south (EC) elevation; these are intended to hold future signage. Wall-mounted lights have been added to the north and south elevations. Two breaks in the parapets on the south elevation have been eliminated. In regard to specific recommendations made by the ARB at the September 5, 2017 meeting, the applicant was asked to submit material and color samples for the final review; while a materials she et was included in the architectural drawings packet for staff review, physical samples will be provided at the ARB meeting on November 20, 2017. In addition, the Board asked the applicant to consider an alternate materials palette that is compatible with those construction materials utilized in Riverside Village, the residential enclave adjacent to the proposed development that is rendered in a contemporary interpretation of the Arts and Crafts style and in a palette heavy in grays, whites, and blues. Staff review of the materials sheet included with the architectural drawings has determined that no changes to the proposed materials palette have been made since the preliminary review submission. 3 The Board also asked the applicant to consider larger apertures on those elevations visible on the Entrance Corridor (as per the architect’s drawings, that would be the west (side), east (side), and south (EC) elevations). The fenestration at the corners of each building, on the second and third floors, were enlarged to doubles on the south elevation (fronting the EC), matching the interior fenestration on those levels. No apertures were added to the west (side) or east (side) elevations, but small alterations to the light configurations, as described in the above paragraph, were made. As for the site plan, the applicant has responded to all comments: the landscaping provided in previous phases of development has been distinguished from currently proposed plantings, while the street trees that are in place have been marked for removal in order to accommodate the proposed construction. The site plan shows all proposed refuse areas (two dumpster pads with enclosures) but no proposed loading or service areas appear to be proposed for the commercial spaces on the first floor of each building. Ground-mounted equipment has not been illustrated, but a roof plan or elevations that show roof-mounted mechanical equipment locations and sizes have not been provided for review. The note that all visibility of mechanical equipment will be eliminated from the EC has been added to the architectural drawings (although “eliminated” is lacking an ‘n’) and to the site plan set. Additional landscaping has been provided around the refuse areas to integrate the dumpsters better into the landscape. A revised landscape plan addressing all of the ARB comments related to providing additional landscaping in strategic areas has been submitted, as has a lighting plan with photometric values that capture all proposed wall-mounted and freestanding light fixtures. As per the ARB comments, the heights and proposed materials of the retaining walls surrounding the plazas have been provided. A final recommendation was to correct the site plans so that the pedestrian connection between Riverside Village and the proposed development, which crosses the northern section of the parking area, is illustrated as a single material. The applicant has explained that the path’s materiality is not consistent but fluctuates between different pavers (herringbone patterned brick within the roadway in Block 2, aggregate concrete crosswalks within the asphalt parking area, and concrete within the parking islands-cum-planting beds), and thus is illustrated correctly on the site plans. ANALYSIS REF GUIDELINE ARB COMMENTS 9/5/17 CURRENT ISSUE RECOMMENDATION GENERAL GUIDELINES Purpose 1 The goal of the regulation of the design of development within the designated Entrance Corridors is to insure that new development within the corridors reflects the traditional architecture of the area. Therefore, it is the purpose of ARB review and of these Guidelines, that proposed development within the designated Entrance Corridors reflect elements of design characteristic of the significant historical landmarks, buildings, and structures of the Charlottesville and Albemarle area, and to promote orderly and attractive development within these corridors. Applicants should note that replication of historic structures is neither required nor desired. None. The building designs are thoroughly modern although, as per the architect’s narrative (see Attachment B), the gable roof form and board-and batten siding and bricks are allusions to regional “agrarian architectural style.” The use of synthetic siding and black bricks laid in a columnar bonding pattern are vague references to traditional building materials, however. The ARB has approved architectural designs on other ECs that exhibit contemporary design vocabularies. This proposed development is in character with the EC (Rt. 20 North), which changes from commercial and suburban in character to residential suburban and then residential rural traveling northward. None. 2 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. 4 The site development is a densification of a formerly rural site, which is in keeping with the Neighborhood Model District zoning for this parcel. Site development and layout is orthogonal and ordered. Landscaping is plentiful but not varied throughout the site (it tends to be zoned). Compatibility with significant historic sites: 3 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. Submit material and color samples for the final review. The architect’s narrative (see Attachment B) calls the gable roofs, use of bricks and board- and-batten siding “agrarian architectural style,” meant to invoke farmhouse typologies in the area. However, the gable roof form and materials are thoroughly modern and not imitative of traditional architectural precedents -- the overall design vocabulary is contemporary. The materials palette has not changed from the previous submission. A materials sheet has been provided as part of the architectural drawing set for staff review; actual samples will be made available to the ARB at the 11/20/17 meeting. None. 4 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. Compatibility with the character of the Entrance Corridor 5 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 and achieving compatibility with the significant historic sites in the area. None. Creating three three-story masses on the street urbanizes, to some extent, a formerly suburban/rural site and serves to screen the residential development to the west. While the minimal setback is not in keeping with the current character of the EC, it is consistent with Neighborhood Model principles and the approved rezoning. None. Site development and layout 6 Site development should be sensitive to the existing natural landscape and should contribute to the creation of an organized development plan. This may be accomplished, to the extent practical, by preserving the trees and rolling terrain typical of the area; planting new trees along streets and pedestrian ways and choosing species that reflect native forest elements; insuring that any grading will blend into the surrounding topography thereby creating a continuous Provide all landscaping required by the previously approved site plan. Distinguish on the landscape plan in the final site plan submittal between the The site was previously cleared and graded in a prior phase of development. The street trees that were planted along the EC as a condition of approval of that earlier phase will be removed for this phase of construction and replaced with new street trees. None. 5 landscape; preserving, to the extent practical, existing significant river and stream valleys which may be located on the site and integrating these features into the design of surrounding development; and limiting the building mass and height to a scale that does not overpower the natural settings of the site, or the Entrance Corridor. previously approved plants and new plants proposed with this phase of development. Also clearly identify any previously approved plants that are proposed to be eliminated from the plan. At three-and-a-half stories (north elevations with pitched roof) in height, the scale of the buildings is taller than what is typically found on this stretch of road, but not necessarily overpowering. Landscaping 7 The requirements of the Guidelines regarding landscaping are intended to reflect the landscaping characteristic of many of the area’s significant historic sites which is characterized by large shade trees and lawns. Landscaping should promote visual order within the Entrance Corridor and help to integrate buildings into the existing environment of the corridor. See previous recommendation. As per the Code of Development, the northern buffer area (the direction called “east” on the architectural set) must have a minimum of four shade trees, three evergreen trees, and 15 evergreen shrubs. This last condition has been met and exceeded. Landscaping is plentiful but not varied throughout the site (it tends to be zoned). Although no one shrub or tree species accounts for more than 25% of the total quantity of shrubs or trees proposed, which is a standard upheld by the ARB to ensure overall landscaping survival, particular species tend to congregate: for instance, all of the trees along the EC are one species, all of those in the parking area another, rather than being mixed throughout the site. Vary the tree and shrub species throughout the entirety of the site. 8 Continuity within the Entrance Corridor should be obtained by planting different types of plant materials that share similar characteristics. Such common elements allow for more flexibility in the design of structures because common landscape features will help to harmonize the appearance of development as seen from the street upon which the Corridor is centered. SPECIFIC GUIDELINES Compatibility with significant historic sites Structure design 9 Building forms and features, including roofs, windows, doors, materials, colors and textures should be compatible with the forms and features of the significant historic buildings in the area, exemplified by (but not limited to) the buildings described in Appendix A [of the design guidelines]. The standard of compatibility can be met through scale, materials, and forms which may be embodied in architecture which is contemporary as well as traditional. The replication of important historic sites in Albemarle County is not the objective of these guidelines. None. The use of a gable roof form and the use of board-and-batten siding and brick are meant to evoke “agrarian architectural style[s]” of the region. At three-and-a-half stories (gable side), the scale is compatible with contemporary development along other ECs and may set the tone for this end of Rt. 20 North. Illustrate the number of benches in each of the plazas. Ensure that each plaza holds a minimum of two benches and that one plaza holds at least four benches. 10 Buildings should relate to their site and the surrounding context of buildings. 6 11 The overall design of buildings should have human scale. Scale should be integral to the building and site design. None. The materials palette has not changed from the previous submission. A materials sheet has been provided as part of the architectural drawing set for staff review; actual samples will be made available to the ARB at the 11/20/17 meeting. The plaza configurations and sizes have not been altered since the last submission. The surrounding wall heights have been delineated, and they range from 1.6’ to 4’ in height and are board-formed concrete. Proposed plaza landscaping and lighting have been addressed in this submission, and six benches have been illustrated within the two middle plazas (three in each). The Code of Development stipulates that each plaza within Block 1 must have at least two benches and that one plaza must have a minimum of four benches (this has not been illustrated on the site plans, but has been called out in a note) as well as a balanced mixture of hardscaping and landscaping. The Code of Development also stipulates that the “Plazas along Route 20… are intended to provide convenient and welcoming pedestrian access from Stony Point Road into neighborhood shops and restaurants on the lower level of the buildings.” This has been achieved in three out of four of the plazas, which have either steps or sidewalks that connect the pedestrian sidewalk along Route 20 with the buildings and the relegated parking area through these open spaces. However, the southern plaza is enwalled on the Route 20 side, offering no access except from the relegated parking area behind the buildings. 12 Architecture proposed within the Entrance Corridor should use forms, shapes, scale, and materials to create a cohesive whole. 7 13 Any appearance of “blankness” resulting from building design should be relieved using design detail or vegetation, or both. None. Rectangular footprints with planar walls are broken by fenestration and entrances on every elevation; balconies, canopies, and awnings; projecting window bays; and a minimal cantilevering on the upper floors that produces overhangs. Landscaping is provided on every elevation. Two single bay windows on the 2nd and 3rd stories of the south (EC) elevation have been enlarged to double bays. None. 14 Arcades, colonnades, or other architectural connecting devices should be used to unify groups of buildings within a development. None. The four plazas serve as connecting devices between the buildings and the residential community to the west. None. 15 Trademark buildings and related features should be modified to meet the requirements of the Guidelines. None. There is no evidence of a trademark design in the submitted drawings. None. 16 Window glass in the Entrance Corridors should not be highly tinted or highly reflective. 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%. Specifications on the proposed window glass should be submitted with the application for final review. Add the standard window glass note to the architectural drawings. The note is provided on floor plans and elevations of the architectural drawings. None. Accessory structures and equipment 17 Accessory structures and equipment should be integrated into the overall plan of development and shall, to the extent possible, be compatible with the building designs used on the site. Provide a site plan that shows all dumpster, loading and service areas, storage areas, mechanical equipment (ground-mounted), above- ground utilities, and any proposed fencing. Provide a roof plan and elevations that show roof-mounted mechanical equipment locations and sizes. Show how visibility of all equipment will be eliminated. Provide landscaping at the dumpster to integrate it into the surroundings. Two dumpster pads are located at the north and south ends of the parking area, on the west edge of the block, behind the buildings, but may be obliquely visible from the EC. Landscaping has been added around the dumpster enclosures to mitigate their visibility. No ground-mounted mechanical equipment is shown on the site plan set yet no roof plan and elevations showing roof-mounted mechanical equipment locations and sizes have been submitted. Provide a roof plan and elevations that show roof- mounted mechanical equipment locations and sizes. Show how visibility of all equipment will be eliminated. 18 The following should be located to eliminate visibility from the Entrance Corridor street. If, after appropriate siting, these features will still have a negative visual impact on the Entrance Corridor street, screening should be provided to eliminate visibility. a. Loading areas, b. Service areas, c. Refuse areas, d. Storage areas, e. Mechanical equipment, f. Above-ground utilities, and g. Chain link fence, barbed wire, razor wire, and similar security fencing devices. 19 Screening devices should be compatible with the design of the buildings and surrounding natural vegetation and may consist of: a. Walls, b. Plantings, and c. Fencing. 20 Surface runoff structures and detention ponds should be designed to fit into the natural topography to avoid the need for screening. When visible from the None. Existing biofilters, created in previous phases of development, are located on adjacent None. 8 Entrance Corridor street, these features must be fully integrated into the landscape. They should not have the appearance of engineered features. blocks, to the south and west. Additional landscaping is proposed for the biofilter west of and adjacent to the parking area in Block 1. 21 The following note should be added to the site plan and the architectural plan: “Visibility of all mechanical equipment from the Entrance Corridor shall be eliminated.” Include the mechanical equipment note on the architectural drawings. The note is provided on the cover sheet of the site plan set and on the floor plans and elevations of the architectural drawings, but “eliminated” is misspelled on the latter. Correct the standard mechanical equipment note on the architectural drawings. Lighting General Guidelines 22 Light should be contained on the site and not spill over onto adjacent properties or streets; Submit a lighting plan which includes all proposed free- standing and wall-mounted lights with the final site plan. There is no spillover of illumination greater than half a footcandle onto adjacent properties. None. 23 Light should be shielded, recessed or flush-mounted to eliminate glare. All fixtures with lamps emitting 3000 lumens or more must be full cutoff fixtures. Model A, a freestanding light pole that is proposed throughout the parking area, is the only fixture that will emit more than 3,000 lumens; it is full cutoff. None. 24 Light levels exceeding 30 footcandles are not appropriate for display lots in the Entrance Corridors. Lower light levels will apply to most other uses in the Entrance Corridors. The highest footcandle value on the entire site is 10.7, which is well under the 20 fc criterion for parcels in the EC overlay district. None. 25 Light should have the appearance of white light with a warm soft glow; however, a consistent appearance throughout a site or development is required. Consequently, if existing lamps that emit non-white light are to remain, new lamps may be required to match them. All light colors are specified as 3000K (warm white) or 4000K (cool white), which is in the white value, or is described as “neutral white.” Ensure that the kelvins emitted by all light fixtures are consistent throughout the site. 26 Dark brown, dark bronze, or black are appropriate colors for free-standing pole mounted light fixtures in the Entrance Corridors. Model A, which is a freestanding pole light, is specified as black. The color of Model B, which is a freestanding bollard, is not specified; however, the model comes in black (BKTX) and bronze (BRTX) finishes. Choose either black or bronze for the Model B bollard lighting and specify choice on the lighting plan. 27 The height and scale of freestanding, pole-mounted light fixtures should be compatible with the height and scale of the buildings and the sites they are illuminating, and with the use of the site. Typically, the height of freestanding pole-mounted light fixtures in the Entrance Corridors should not exceed 20 feet, including the base. Fixtures that exceed 20 feet in height will typically require additional screening to achieve an appropriate appearance from the Entrance Corridor. Model A, which is a freestanding pole light, spans 15’ high from grade, including the concrete base. Model B, which is a freestanding bollard, is 3.3 feet tall. None. 28 In determining the appropriateness of lighting fixtures for the Entrance Corridors, the individual context of the site will be taken into consideration on a case by case basis. The lighting fixtures chosen are appropriate for the EC overlay district. None. 9 29 The following note should be included on the lighting 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.” The note is provided on Sheet C12 of the site plan set. None. Guidelines for the Use of Decorative Landscape Lighting 30 light used for decorative effect shall: a. be compatible with the character of the Entrance Corridor. Compatibility of exterior lighting and lighting fixtures is assessed in terms of design, use, size, scale, color, and brightness. b. impact only the immediate site. The effect of the illumination should not be discernible from distances along the Entrance Corridor. Submit a lighting plan which includes all proposed free- standing and wall-mounted lights with the final site plan. No landscape lighting proposed. None. 31 Where used for decorative effect, outdoor light fixtures shall: a. be equipped with automatic timing devices and shall be extinguished between the hours of 11:00 p.m. and dawn. b. be shielded and focused to eliminate glare. Glare control shall be achieved primarily through the use of such means as cutoff fixtures, shields and baffles, and appropriate application of mounting height, wattage, aiming angle, fixture placement, etc. c. be cutoff luminaires, aimed so as not to project their output beyond the objects intended to be illuminated; or non-cutoff luminaires, equipped with glare shields, visors, barn doors, and/or other similar shielding accessories as required to meet the following criteria: Light distribution from all lighting installations shall be cut-off at all angles beyond those required to restrict direct illumination to within the perimeter of the landscape feature being illuminated. d. never exceed 3,000 lumens. Further restrictions on lumens may be imposed by the ARB. e. not be modified to reflect seasonal colors. f. be of a number that is compatible with the scale of the object and the development to be illuminated, such that the light emitted will not over- illuminate or overpower the site, as determined by the ARB. Landscaping 32 Landscaping along the frontage of Entrance Corridor streets should include the following: a. Large shade trees should be planted parallel to the Entrance Corridor Street. Such trees should be at least 3½ inches caliper (measured 6 inches above the ground) and should be of a plant species common to the area. Such trees should Provide a landscape plan in a site plan format. Rectify the omission of plant quantity and symbol on the plant material schedule and 13 London Planetrees (PA) are proposed along the EC, replacing the street trees that were planted in a previous phase of development and that will be removed for this phase of construction. The proposed trees are Consider adding ornamentals between the large shade trees (London Planetrees) proposed for the EC frontage. 10 be located at least every 35 feet on center. b. Flowering ornamental trees of a species common to the area should be interspersed among the trees required by the preceding paragraph. The ornamental trees need not alternate one for one with the large shade trees. They may be planted among the large shade trees in a less regular spacing pattern. c. In situations where appropriate, a three or four board fence or low stone wall, typical of the area, should align the frontage of the Entrance Corridor street. d. An area of sufficient width to accommodate the foregoing plantings and fencing should be reserved parallel to the Entrance Corridor street, and exclusive of road right-of-way and utility easements. coordinate symbols on the landscape plan for the final site plan submission. Distinguish on the landscape plan in the final site plan submittal between the previously approved plants and the new plants proposed with this phase of development. Also clearly identify any previously approved plants that are proposed to be eliminated from the plan. Provide the heights and proposed materials of the walls encircling the plazas. 3.5” caliper and average between 30’ and 35’ o.c. This street planting is consistent, for the most part, with previously approved quantities and character as illustrated in ZMA2016-19, approved on May 10, 2017 [Figure 1]. Whereas the ZMA shows a total of 10 street trees tightly grouped into two sections of five with a large break in the middle, the proposed access points to the interior plazas and buildings have necessitated three breaks (providing access to the plazas) and another three minor breaks (providing access to the centralized entrances on each building’s south façade), creating three sections of four trees with an additional tree on the north (total of 13 trees, which exceeds the 10 illustrated in the ZMA). While the tree canopies in the ZMA are shown as overlapping, those in this submission nearly touch; the gaps between trees, although closely spaced at 30’-35’ o.c., could be infilled with smaller ornamental trees (no ornamentals interspersed between the large shade trees are currently proposed). No fencing is proposed along the EC. The proposed planting area appears to be able to accommodate the proposed plantings. The plant quantities and symbols listed in the plant materials schedule coordinate on the landscape plan. Plaza wall heights and proposed materials have been provided in the site plan set and in the architectural drawings, respectively. The heights range from 1.6’ to 4’ and the proposed material is board-formed concrete. 11 Figure 1: “Stony Point Road Improvement Proposed,” in Rezoning Application Plan for Riverside Village, provided by Shimp Engi neering, Sheet 7 of 7, date 5/21/2012, last revision date 4/10/2017. Approved in ZMA2016-19 on May 10, 2017. 33 Landscaping along interior roads: a. Large trees should be planted parallel to all interior roads. Such trees should be at least 2½ inches caliper (measured six inches above the ground) and should be of a plant species common to the area. Such trees should be located at least every 40 feet on center. Add street trees in the gaps along the north side of Trailside Drive in the vicinity of the entrance into the Block 1 parking lot. Three Willow Oaks (QP) have been added to the north side of Trailside Dr. in response to ARB comments made 9/5/17. They are 2.5” caliper and average 40’- 42’ o.c. Three Katsuras (CJ) are proposed for the south side of the north entrance to Block 1; these are medium trees, not large shade trees. However, these proposed trees are 2.5” caliper and 28’ o.c., a spacing much closer than the required 40’ o.c., which is preferable. One Red Maple (AR, 2.5” caliper) is proposed for the north side of the north entrance. Four Swamp Oaks (QB; large shades) are proposed along the pedestrian connection from Block 2 to the west and Block 1, while eight Elms (UA; large shades) are proposed along the sidewalk west of the buildings; all are 2.5” caliper and average 25’ o.c. along pedestrian connection. However, the spacing along the sidewalk varies from 45’-95’ o.c. 20 ornamentals (AC) line the two middle plazas (7-8’ Ht; 5’-17’ o.c.), while the end plazas are fitted with large shade trees. The south plaza has three Black Gums (NS) while the north plaza has seven Japanese Stewartias (SP), a minimal palette with no diversity. Vary the tree and shrub species throughout the entirety of the site. 34 Landscaping along interior pedestrian ways: a. Medium trees should be planted parallel to all interior pedestrian ways. Such trees should be at least 2½ inches caliper (measured six inches above the ground) and should be of a species common to the area. Such trees should be located at least every 25 feet on center. 12 35 Landscaping of parking areas: a. Large trees should align the perimeter of parking areas, located 40 feet on center. Trees should be planted in the interior of parking areas at the rate of one tree for every 10 parking spaces provided and should be evenly distributed throughout the interior of the parking area. b. Trees required by the preceding paragraph should measure 2½ inches caliper (measured six inches above the ground); should be evenly spaced; and should be of a species common to the area. Such trees should be planted in planters or medians sufficiently large to maintain the health of the tree and shall be protected by curbing. c. Shrubs should be provided as necessary to minimize the parking area’s impact on Entrance Corridor streets. Shrubs should measure 24 inches in height. Add shrubs along the eastern edge of the parking lot where buildings do not block parking spaces from the EC. Shrubs were added to the western (north, on the architectural drawings) side of the plazas, fronting the parking area. The visibility of the parking area from Route 20, through the plazas, will be further mitigated by the proposed walls, which range in height from 1.6’ to 4’. 13 Swamp Oaks (QB; large shades) are dispersed throughout the parking area’s interior. Sheet C12 of the site plan set states there are 111 parking spaces listed on C12, but staff counted 118. For the standard of 1 tree per 10 parking spaces, 12 trees are required; 24 trees (13 QB and 11 UA) are provided. All are 2.5” caliper. Six Elms (UA; large shades) are provided on the north and south perimeter of the parking area; each is 2.5” caliper. Those on the north average 30’ o.c. spans. All shrubs in the plant schedule are listed as 24” high at planting. None. 36 Landscaping of buildings and other structures: a. Trees or other vegetation should be planted along the front of long buildings as necessary to soften the appearance of exterior walls. The spacing, size, and type of such trees or vegetation should be determined by the length, height, and blankness of such walls. b. Shrubs should be used to integrate the site, buildings, and other structures; dumpsters, accessory buildings and structures; “drive thru” windows; service areas; and signs. Shrubs should measure at least 24 inches in height. Provide at least two (2) benches in all plazas. Design the northernmost plaza as a focal point of the block. Correct the site plans so that the pedestrian connection is a single material. Shrubs and ornamental grasses are proposed for all elevations and within the plazas. Shrubs are also proposed around the refuse areas and plaza walls. As per the Code of Development, each plaza within Block 1 should have at least two benches and one plaza must have a minimum of four benches (this has not been illustrated on the site plans but has been called out in a note) and a balanced mixture of hardscaping and landscaping. The applicant maintains that the northernmost plaza is the focal point of the block as it is the largest of the four open spaces and as the pedestrian connection from Block 2 terminates in the plaza while steps lead to the sidewalk along Route 20, inviting any pedestrian traffic along the corridor into the proposed development. Illustrate the number of benches in each of the plazas. Ensure that each plaza holds a minimum of two benches and that one plaza holds at least four benches. 13 The materiality of the pedestrian connection between Block 2 to the west and Block 1 is not singular, but fluctuates between different pavers (herringbone patterned brick within the roadway in Block 2, aggregate concrete crosswalks within the asphalt parking area, and concrete within the parking islands- cum-planting beds), and thus is illustrated correctly on the site plans. 37 Plant species: a. Plant species required should be as approved by the Staff based upon but not limited to the Generic Landscape Plan Recommended Species List and Native Plants for Virginia Landscapes (Appendix D). None. The proposed plant species are acceptable. None. 38 Plant health: 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. Shrubs and trees shall be pruned minimally and only to support the overall health of the plant.” Provide the standard health plant note on the landscape plan. The note is provided on Sheet C9 of the site plan set. None. Site Development and layout Development pattern 39 The relationship of buildings and other structures to the Entrance Corridor street and to other development within the corridor should be as follows: a. An organized pattern of roads, service lanes, bike paths, and pedestrian walks should guide the layout of the site. b. In general, buildings fronting the Entrance Corridor street should be parallel to the street. Building groupings should be arranged to parallel the Entrance Corridor street. c. Provisions should be made for connections to adjacent pedestrian and vehicular circulation systems. d. Open spaces should be tied into surrounding areas to provide continuity within the Entrance Corridor. e. If significant natural features exist on the site (including creek valleys, steep slopes, significant trees or rock outcroppings), to the extent practical, then such natural features should be reflected in the site layout. If the provisions of Section 32.5.6.n of the Albemarle County Zoning Ordinance apply, then improvements required by that section should be located so as to maximize the use of existing features in screening such improvements from Entrance Corridor streets. f. The placement of structures on the site should respect existing views and vistas on and around the site. None. The development exhibits an organized pattern of roads, service lanes, and pedestrian walks. Buildings fronting the EC are parallel to the street. A proposed pedestrian connection differentiated in alternating paving materials links this block with the residential development to the west, through the parking area. Open spaces are provided by four plazas totaling 5,000 square feet as per the Code of Development, and trees have been proposed as landscaping elements that offer continuity with development along the EC. As the site was cleared and graded previously, no significant natural features are present on the site. None. 14 Site Grading 40 Site grading should maintain the basic relationship of the site to surrounding conditions by limiting the use of retaining walls and by shaping the terrain through the use of smooth, rounded land forms that blend with the existing terrain. Steep cut or fill sections are generally unacceptable. Proposed contours on the grading plan shall be rounded with a ten foot minimum radius where they meet the adjacent condition. Final grading should achieve a natural, rather than engineered, appearance. Retaining walls 6 feet in height and taller, when necessary, shall be terraced and planted to blend with the landscape. None. The site was previously cleared and graded as part of previous development. The parcel is relatively flat, with a slight incline from south to north. The north end of the site has a steep slope (buffer) that must be planted with at least four shade trees, three evergreen trees, and 15 evergreen shrubs as per the Code of Development. This requirement has been met in the proposed landscape plan, specified on Sheet C11. Two retaining walls adjacent to the two refuse areas are called out as 10’ max height. The retaining walls around the plazas range in max height 1.6’ to 4’ and are board-formed concrete. There is a wall-like element drawn on Sheet C4 of the site plan set, near the curved monument sign at the entrance to Trailside Drive, on the southeast end of the block, that is not called out. Retaining walls six feet and higher must be terraced and planted. Specify retaining wall material. Clarify the wall-like element on Sheet C4 which is near the curved monument sign/wall in the southeast corner of the block, near the throat of Trailside Drive. 41 No grading, trenching, or tunneling should occur within the drip line of any trees or other existing features designated for preservation in the final Certificate of Appropriateness. Adequate tree protection fencing should be shown on, and coordinated throughout, the grading, landscaping and erosion and sediment control plans. None. All pre-existing trees have been cleared from the site in previous phases of development; some trees have been planted along the EC (Rt. 20), but these will be removed and replaced in this phase of construction. However, one Willow Oak (QP) exists on the southeast corner of the parcel, to the north of Trailside Drive. If the intention is to keep this tree, its preservation should be marked on the site plans. Show adequate tree protection for any existing trees to remain on the site during construction. 42 Areas designated for preservation in the final Certificate of Appropriateness should be clearly delineated and protected on the site prior to any grading activity on the site. This protection should remain in place until completion of the development of the site. 43 Preservation areas should be protected from storage or movement of heavy equipment within this area. 44 Natural drainage patterns (or to the extent required, new drainage patterns) should be incorporated into the finished site to the extent possible. 15 SUMMARY OF RECOMMENDATIONS Staff recommends the following as the primary points of discussion: 1. The need to vary tree species throughout the entire site versus a possible design intention that “zones” species throughout a site. Staff offers the following comments on the proposal: 1. Vary the tree and shrubs species throughout the entirety of the site. 2. Illustrate the number of benches in each of the plazas. Ensure that each plaza holds a minimum of two benches and that one plaza holds at least four benches. 3. Provide a roof plan and elevations that show roof-mounted mechanical equipment locations and sizes. Show how visibility of all equipment will be eliminated. 4. Correct the standard mechanical equipment note on the architectural drawings. 5. Ensure that the kelvins emitted by all light fixtures are consistent throughout the site. 6. Choose either black or bronze for the Model B bollard lighting and specify choice on the lighting plan. 7. Consider adding ornamentals between the large shade trees (London Planetrees) proposed for the EC frontage. 8. Retaining walls six feet and higher must be terraced and planted. Specify retaining wall material. 9. Clarify the wall-like element on Sheet C4 which is near the curved monument sign/wall in the southeast corner of the block, near the throat of Trailside Drive. 10. Show adequate tree protection for any existing trees to remain on the site during construction. 11. Add all drawing and revision dates as well as correct sheet numbers to the site plan set and to the architectural drawings. Correct Sheet C11 title “Existing Landscape Plan,” to “Landscape & Lighting Plan Details.” 16 TABLE A This report is based on the following submittal items: Sheet # Drawing Name Drawing Date/Revision Date 1st Floor Plan 10/9/17 2nd & 3rd Floor Plan 10/9/17 North Elevation 10/9/17 South Elevation 10/9/17 East Elevation 10/9/17 West Elevation 10/9/17 Perspective from Rt. 20 10/9/17 Perspective from Parking Lot 10/9/17 Site Section Along Rt. 20 10/9/17 Material Palette 10/9/17 Paving and Walls 7/24/17 Plant Schedule 10/9/17 C1 Cover Sheet 6/16/17 C2 Approved Proffers & Lot Regulations 6/16/17 C3 Existing Conditions & Demo Plan 6/16/17 C4 Site Plan 6/16/17 C5 Grading Plan 6/16/17 C6 Utility Plan 6/16/17 C7 Utility Profiles 6/16/17 C7 [sic] Utility Details 6/16/17 C9 Roadway Profile & Details 6/16/17 C9 [sic] Landscape Plan & Details 6/16/17 C11 Existing Landscape Plan 6/16/17 C12 Lighting Plan & Details 6/16/17 17 ATTACHMENT A 18 ATTACHMENT B
