HomeMy WebLinkAboutARB201900047 Plan - Revision 2019-06-25FLOW AUTOMOTIVE MAZDA/ VOLKSWAGEN OF CHARLOTTESVILLE SHOWROOM & SERVICE CENTER ARB Submittal June 24, 2019 This submission includes 2 new automotive dealerships; which are separate entities but situated on adjacent properties at Pantops Corner of Route 20 & 250. The new Mazda Dealership will be located in the same location as the existing Mazda (1289 Stony Point Rd.); replacing the 1970's CMU block structure to be demolished. In its place, the new Mazda will provide all the amenities of a full -service dealership: an up-to-date showroom with wait- ing areas and offices, a vehicular drop off station as well as a new Service Bay Garage. While the new Mazda complex occupies a similar footprint as the old, it will provide a much -improved plan for both internal daily business operations as well as on the exterior increasing the efficiency of the site and improving its circulation. Just as important and related to the E.C. review, the new Showroom/Service Center will provide a much -need- ed upgrade from the existing - a somewhat dilapidated structure on an unimproved site. We see this project as an opportunity to enhance the character of the corner by improving the Site Plan with better organization and improved county recommended landscaping. And from an architec- tural standpoint, the project replaces the existing with a new building that addresses the corner and is more suitable to its prominent location. The current Mazda design standard is a contemporary style. Subdued with a simple combination of light and dark metal paneling, the exterior facade shows enough variety to create and maintain interest but not overly flamboyant so as to overwhelm the rest of the character on the corner or go against precedent on the 250 corridor. Large storefront windows are added to the facade which rounds out the material palette and provides a healthy amount of daylighting for the interior. Mazda's main design feature - referred to as 'the jewel box' - is a 2 story room enclosed in a glass frame that encourages one's gaze on the outside into the interior environment. This 'jewel box' seems an appropriate answer for addressing the Pantops Corner at this difficult site. Its prominent but well proportioned oversized glass wall is oriented toward the corner and enhances the impor- tance of its location. Further, the interior wall of the jewel box is lined with a wood plank the which forms a warm contrast to the exterior and materially ties into the local vernacular. The limitations of this particular site is an undeniable aspect of assessing both project plan layouts. As the diagrams on the following page illustrate, a major feature of the site is the established electric easement cutting across a large section of the south east corner; directly related to the large high voltage power lines overhead. Although many would agree in recom- B R W A R C H I T E C T S 112 fourth street NE charlottesville virginia 22902 434.971.7160 www.brw-architects.com mending positioning the building's prominent corner (and jewel box) closer to the street edge, the easement has forced us to locate the building to- ward the rear of the site. You will also notice that the easement - in running diagonally across the site - pinches the southern portion. This circumstance along with the presence of steep slopes - shifts the Mazda building toward the north west section. Vehicular circulation is another major component limiting options on how the site might be laid with safe and efficient traffic flow. Engineering rec- ommendations for limiting entry to a shared access make the notion of efficient traffic flow paramount to this already tight, oddly shaped site. The current building plans strategically place the customer drop off garage as close as possible to the main road entry - which thereby reduces the amount of cars driving around the parking lot. In addition both dealer drop-off stations - which have to be adjacent to the showroom - are also situated where a more private drive connects the drop off to the service garage. The new VW complex (1311 Stoney Point Road) will provide the same full -service amenities as Mazda and is located on the next parcel down on the lot that currently includes the old Rexall building and also a smaller out -building to the north; both of which are slated for demolition. Other than the buildings mentioned above, the nature of this lot is mostly an old parking lot and overgrown vegetation. Unlike Mazda, which is oriented orthogonal to Rt. 250, VW orientation turns its front facade to run parallel to Rt. 20; helping to reinforce and maintain a street edge. With the electrical easement less of a constraint on this parcel, the major limitation is the site's long and skinny proportion. As with Mazda, the buildings orientation allows for immediate proximity from the Entry to vehicular drop-off as well as an efficient connector driveway from drop off zone to Service Bays. As with Mazda, the entry to the Service Bays are hidden/screened from site by the main building. As with Mazda, this particular site layout is advantageous in allowing for efficient daily operations and a plus for the Entrance Corri- dor in the way it limits the visual noise of constant visible moving vehicular traffic on site. While these projects will be under one ownership, as 2 unrelated corpora- tion on different parcels, they are considered separate projects. However, given their adjacency and location on an important corner of the En- trance Corridor; the county recommended studying them together given the impact they will ultimately have in the area. We look forward to work- ing with the county in providing the best possible design solutions. Ls PROJECT NARRATIVE FLOW MAZDA/ VOLKSWAGEN AUTOMOTIVE SHOWROOM & SERVICE CENTER ARB Submittal June 24, 2019 0 R W A R C H I T E C T S 112 fourth street NE charlottesville virginia 22902 434.971.7160 www.brw-architects.com Response Memo to County Recommendations Revise Forms, proportions, scale and materials to achieve greater balance of contemporary design with historic compatibility • VW - The following are changes made in response to the above recommendation: o Reducing Length of Front Fagade and in turn diminishing the front curtain wall. A major design revision was achieved by removing the Ser- vice Bay Doors from the main glass front fagade and pushing the entire Service Bay front back from the main fagade by 15'. This revision relates to the Design Guidelines by breaking down the building scale, reducing the sense of blankness of the original predominantly glass front facade, and fostering greater connection to the local historic fabric. o Numerous Material Changes: Both the addition of stone paneling replacing VW's white metal paneling and the addition of brick create a greater balance of contemporary with Historic compatibility. • Mazda - o Replacing all white metal paneling with Brick - A good deal of the original Mazda design included white metal paneling that we are now substituting for brick. o Addressed further breaking down the scale of the Service Bay block through material detailing. While the original design begins to break down the scale of the entire building by different 'sub-massses' , the Service Bay scale and proportion has been revised in this revision by bringing the new brick down to the corner. This move elimi- nates the stark contrast between the upper and lower half of this volume - which created a sense that the upper white sec- tion was floating - and in turn creates a sense of 'grounding'. In addition, the revised design articulates patterning through detailing reveals within the brick; which helps to break down and lend interest to the brick face. FLOW MAZDA/ VOLKSWAGEN AUTOMOTIVE SHOWROOM & SERVICE CENTER ARB Submittal June 24, 2019 2. Revise the architectural designs to use forms, features, materials and colors that are compatible with the forms and features of signif- icant historic buildings in the area. Consider brick or stone or other natural materials instead of metal panels. Consider revising the massing of the VW service drop-off. • VW o Per Board's recommendation, we revised the Service Drop off Bay - disenagaing it from the main front facade; thereby breaking down the scale of the overall structure. Now appearing as a smaller volume beside the larger show- room, this redesign is more in keeping with the local context by reducing the extent of the main glass facade and creat- ing a larger to smaller relationship that not only relates better to the surrounding historic structures but also to the Mazda design. o Stone - particularly limestone paneling - shall replace the orignal white metal paneling on the design main frames. o Brick is now being used as a secondary accent material ink cluding at the front elevation of the Service Bay. Adding a material more in keeping with the local building material palette. • Mazda o Brick shall replace all white metal paneling A major shift in the predominant building skin that brings the design more in line with the local context. 3. Provide Details proposed curtain wall • See included detail drawings 4. Clarify that the windows in the service wing use vision glass • Confirmed 5. Revise Design to emphasize human scale • VW o The new revised massing reduces the overall scale of the building by breaking it down to a major and minor volume; thereby moving from a more monumental design to one more in line with the human scale. o The Entry Portals within the Showroom glass facade help re- late the 2 story structure to the human scale and provide an instantly recognizeable entry element for the B R W A R C H I T E C T S 112 fourth street NE charlottesville virginia 22902 434.971.7160 www.brw-architects.com pedestrian. Also the entry now clad in limestone - were reduced in size upon redesign. o The new material change provides a warmer, more tex- tured and sensory experience for the human scale. • Mazda o The Mazda Design breaks down the entire complex into a series of massings more in keeping with the human scale. o Although a 2 story space, the Mazda 'Jewel Box' is lined inside with a warm wood the that relates better to the human scale vs a colder ma- terial. o As with VW, the Mazda switch to a majority of exterior brick as a new material change provides a warmer, more textured and sensory experience for the human scale. 6. Revise Design to establish greater coordination with nearby buildings. • VW o With a change of materials - brick and stone - we are relating the new VW to the best precedents within the surrounding context. o The building's orientation on site also reflects the inten- tion of defining the street edge while also hiding the Service Bay volume to the rear of the site. 0 • Mazda o The reduction of a majority of the metal paneling. 0 White Brick - there are many examples of brick / stucco palette within the corridor. With the grey to white combination, we are striving for an elegant solution that on the other hand doesn't call too much attention to itself and fits well within the sur- rounding fabric. 7.

The simplicity of the glass and metal paneling puts a focus on materiality of the facade and again avoids the fussiness that is contrary to our historic context. B R W A R C H I T E C T S 112 fourth street NE charlottesville virginia 22902 434.971.7160 www.brw-architects.com Both buildings seem to fit within the wide range of structures located at the intersection. Buildings should have a human scale Both Dealerships provide a strong sense of entry and scaling mecha- nisms that deal with human scale in that they allow people to relate to the scale of the complexes in a personal way. Compatibility with the Character of the Entrance Corridor The size and scale of this building compares appropriately with the size and scale of buildings on both sides of the Entrance Corridor. It would fall into the moderate range in comparison to other buildings in the area. The Entrance Corridor along US 250 east of Charlottesville at Pantops represent a diversity of architectural approaches to design and scale. Stylistically, both dealerships appear to fit within this wide range of styles and one may argue enhances the Corridor with their well detailed design standards. Both Dealerships suggest a contem- porary design with simple yet varied materials; that leads to a classical elgance through their simplicity. Further one might argue that both de- signs provide visual interest while avoiding the 'overly fussy' that often lead to a lot of visual noise in high traffic areas. The Appearance of Blankness Should be relieved using details or vegetation The Site Plan shows a good deal of improvement in regards to the Landscaping. While the electric easement limits not only building placement but also the variety of tree we can use (it has to be a smaller understory), our proposed landscape shows a multi -layered tree layout (using native species) that both strengthens street edge but also creates a buffer at this busy intersection. Form, Shape, Scale, and Material Creating a Cohesive Whole The two dealerships deal with the idea of form and shape in different ways but both provide designs that allow for a massing and compos- tion appropriate to the Entrance Corridor. Mazda breaks its facade down into a variety of forms and emphasiozes priority of function through a series of diffierent sized masses. Materiality and the variety of major and minor shapes help tie the overall composition together. This strategy breaks down the overall scale of the building and avoids the monotony and blankness on less successful designs. On the other hand, VW maintains a design that is more singular and its scale ius broken down by the various portal or gates the denote Entry and the other major functions of the dealership. As a whole, the VW design seems to work as a simple, framed box that is well detailed and again emphasizes a contemporary simplicity.

streets and widest sidewalk setbacks in Burlington. As deemed appropriate by the City Arborist, this condition may remain in selected areas in order to preserve large, healthy trees. However, this condition is prone to compaction and erosion in areas with adjacent on -street parking and/or high levels of pedestrian activity. This condition should be replaced with the standard tree belt as blocks are redeveloped when trees are in struggling condition or where preservation of the existing green belt is infeasible. Where these green belts are more than 8' wide, large, open soil volumes are often sufficient to support trees which survive to produce large canopies. Soil cells may be used beneath pavements if necessary to provide required soil volumes to new trees. Small, medium, and large tree species are suitable for planting in these conditions. Standard Green Belt This is the historic green belt condition in downtown. However, this condition is only desirable on primarily residential streets with low foot traffic and on blocks with slopes of less than 5%. Therefore, this condition may remain in selected areas as indicated in the Proposed Tree Belt Condition diagram. In order to protect against compaction and erosion that can damage roots and turf, an 18" "carriage walk" should be installed along the curb line within the green belt where possible. Soil cells may be utilized beneath pavements if needed to provide required soil volumes for new trees. Otherwise, horticultural soils should be used in unpaved portions of the green belt at a minimum depth of 36". Small, medium, and large tree species are suitable for planting in these conditions. Narrow Tree Belt This tree belt type exists where a narrow ROW accommodates only a slender green belt. In the future, this condition is only appropriate on primarily residential streets with low pedestrian traffic and where there is already a narrow/substandard green belt. In this condition, soil volumes in the green belt alone are insufficient to support trees which survive to produce large tree canopies. Soil cells or root trenches shall be used underneath pavement to provide required soil volumes for new trees. Only small tree species are appropriate for planting in these conditions. Public Sidewalk Horticultural Soil Iched Tree Well r Broad green belt condition with 8'+ of turf between the curb and sidewalk. Urban Lawn Mix Public Sidewalk a Soil Cell Well Horticultural Soil Standard green belt condition with an 78" "carriage walk" adjacent to the curb to protect tree roots and turf from erosion from adjacent on -street parking. Urban Lawn Mix Narrow green belt condition with soil cells to support small tree species. Downtown Street Design Standards DRAFT November 2017 City of Burlington 163 Street Ecology: Street Trees Tree Planting Details TREE PLANTING ATTREE WELL Trees planted within green belts shall follow all "Tree Installation Guidelines" on page 764, as well as these additional details. Groundcover • Plant Groundcover to cover the soils beyond the rootball. • Select Groundcover species from the recommended list in this document. Mulch • Option: Mulch at a 2" depth to cover entire soil surface within Downtown Street Design Standards DRAFT November 2017 City of Burlington 167 Street Ecology: Street Trees Tree Protection HORTICULTURAL SOIL Intent: To provide trees, turf, and groundcover plantings with a soil that allows them to thrive and to live out their longest possible healthy life in urban conditions. Location: Horticultural soils will fill the entire area of the tree well at a 3' minimum depth. These soils will also be used in soil cells and will provide the top 18" of the soil profile in turf Treebelts. Horticultural Soil is not intended for use in Bio-retention Plantings. Design: Consult a soils scientist or a licensed landscape architect, horticulturist, or arborist when designing Horticultural Soils to meet site and plant specific needs. Materials: Horticultural Soil is a fertile, friable, loamy topsoil mix suitable for the support of vegetative growth. Horticultural Soil Components: Topsoil, Organics, Coarse Sand, Fertilizer, and Biological Amendments • Topsoil: Unscreened Imported Topsoil or Existing Site Soil - Soil Texture: USDA loam, sandy clay loam, or sandy loam. - Soil Structure: Retain Peds of min 2" in size prior to mixing. - Organic Matter & Soil Chemistry: Suitable for growing the plants specified at the designed location - Soil Objects: < 5% of total topsoil volume: Clumps of Clay; Debris; Refuse; Roots; Stones; Sticks; Brush; or other litter. Remove all soil - objects >8" in their longest dimension. - Contaminants. The soil should have no herbicides, heavy metals, biological toxins, or hydrocarbons that will impact plant growth or are at levels exceeding the EPA's standards for soil contaminants. - Source: Unscreened Imported Topsoil must be harvested within 50 miles of Burlington, Vermont. Unscreened Imported Topsoil may not contain soils from sources defined by the United States Natural Resources Conservation Service as prime farmland, unique farmland, or farmland of statewide or local importance. • Organics: Compost shall be commercially prepared Pine Fines or an equivalent compost and must meet US Compost Council STA/TMECC criteria for "Compost as a Landscape Backfill Mix Component" and must not be derived from human waste or animal waste sources. • Coarse Sand: Clean, washed, natural sand, free of toxic materials, limestone, salt, shale, and slate particles. Must meet ASTM-03 Standards. • Fertilizer: If noted by soil test recommendations, add slow -release, organic fertilizer based on soil test and plant requirements. • Biological Amendments: Amendments such as Mycorrhizal additives, compost tea or other products intended to change the soil biology, as required based on Soil Foodweb Analysis by a qualified soil testing lab. Horticultural Soil Mix Requirements: Blend Topsoil, Organics, Coarse Sand, Fertilizer & Biological Amendments to make a new soil that meets the Project goals for the indicated planting area. • Clay content:15-25% by weight • Organic matter: 5-10% by weight • Coarse Sand: 30-65% by weight • Silt:15-25% by weight • Gravel content shall not exceed 10% by weight • Soluble Salt: < 2 dS/m • Cation Exchange Capacity: 7-15 • Water Permeability: 1-2 inches per hour when compacted to 85% of maximum dry density • pH: 6.0-6.5 • At the time of soil installation, add fertilizer or biological amendments, if required, to the planting soil mix at rates recommended by soil testing results for the plants to be grown. Depth: 3-4' (18" in turf -only areas of tree -belts where tree rooting volume is not required). SOILCELLS Intent: Soil Cells provide most the required soil volume for each tree downtown. These systems protect tree rooting soil from compaction while allowing pavement, vehicular access, and other streetscape uses above. Location: The primary location for these systems will be beneath permeable pavement in the Treebelt. These systems may also extend beneath the Concrete Sidewalk, Paved Bike Lanes, and in the Step -off zone. In residential areas, there the tree -belt is planted in turf Systems: Three systems are approved: • Silva Cells: manufactured by DeepRoot • StrataVault: manufactured by GreenBlue Urban • StrataCell: manufactured by GreenBlue Urban Loading: Soil Cells must be designed to accommodate H-20 loading for all pavements that they support. Soil Type: Install Horticultural Soils in Soil Cells. Horticultural Soil Mix Requirements may be modified to meet manufacturer's specifications. Downtown Street Design Standards DRAFT November 2017 City of Burlington 173 Tree Protection Street Ecology: Street Trees Installation: Per Manufacturer specification to accommodate paving and streetscape furnishings above as well as tree grate or curb/fence. CU-STRUCTURAL SOIL TM Intent: CU Structural Soil is a less -costly, but less -efficient method of providing rooting space for street trees beneath pavements as compared to Soil Cell systems. Materials: CU Structural Soil is a patented mixture of crushed stone, clay loam and Hydrogel developed by Cornell University. (Patent #5,849,069) Installation: Install per "CU-Structural Soil° A Comprehensive Guide" as published by Cornell University: http://www.hort. cornell.edu/uhi/outreach/pdfslCU-Structural %20Soi1 %20-%20 A%20Comprehensive%20Guide.pdf Efficiency: The Smiley -Bartlett Field Study suggests that a cubic foot of CU Structural Soil is capable of supporting 20% as much mature tree canopy volume as uncompacted Horticultural Soil. Use: In areas where soil cells cannot be used because of utilities or other underground impediments, CU Structural Soil may be used to provide no more than 10% of the required soil volume for each tree. CU Structural Soil may also be used to provide root paths beneath paved areas. Root paths provide access to nearby soils suitable for supporting tree growth that would otherwise be made inaccessible by compacted subsoils beneath paved areas. Source: CU-Structural Soil has been patented and licensed to qualified producers to ensure quality control; its trademarked names are CU-Structural Soil® or CU-Soil®. Obtain CU-Structural Soils an Amereq-licensed company. This assures that the material has been produced and tested to meet research -based specifications. DRAINAGE & ROOT AERATION Intent: To prevent subgrade moisture oversaturation and provide subsurface aeration in areas of tree planting. Material: Linear perforated subsoil drains which connect to the city's storm/combined sewer system. Operability: Valves that can cut off drainage to the city sewer systems must be installed at each connection to the sewer system. Valves will be installed in the "off" position. Alternatively, drains may be installed without valves, at a higher elevation in the soil profile as agreed upon with the Burlington Water Resources Department. This overflow system will drain automatically when saturation reaches a designed level. Pvc check -wells must be installed to monitor subgrade moisture at each street tree. Location: Underdrainage must be installed beneath all new street trees, regardless of the pre -construction infiltration rate of site soils. Drains must be installed in tree -belts beneath permeable pavements, tree wells, turf Treebelts, Soil Cells, and Sand Based Structural Soils. Performance: Underdrains must allow saturated soils to drain by gravity to a moisture level that can support the growth of street trees. SUBGRADE On sites where water infiltration is appropriate beneath planting soils: Prior to installing planting soil, loosen grade below the installed planting sol to a depth of 18 inches below the sub grade elevation in areas that are compacted and do not easily drain. Locate and avoid disturbing any existing utility lines or other subgrade structures. Percolation tests shall be performed to confirm minimum percolation rates of 1-2 inches per hour. On sites where water infiltration is inappropriate, provide impermeable liners and drainage pipes to drain all subsoil water into the sewer system while maintaining adequate moisture levels to support healthy plants. 174 City of Burlington DRAFT November 2017 Downtown Street Design Standards Street Ecology: Street Trees Tree Belt & Green Belt Typologies 8' Wide Brick Tree Belts Tree Belt with Planted Tree Wells This should be applied in commercial and mixed use areas with moderate pedestrian activity and where the preferred dimensions for the Pedestrian Zone for cross sections can be met. This may be installed adjacent to a Buffer Zone or a Protected Bike Facility at the sidewalk grade, such as the western blocks of Main Street. Trees in this condition are surrounded by salt -resilient plantings in a bed that infiltrates stormwater. Tree wells are typically 16' long, and are framed by 6" wide granite curbs on the sides parallel to the street with metal tree fencing on the perpendicular sides. Only large tree species are appropriate in this condition. See additional tree planting details in "Tree Planting at Tree Well" on page 185. Tree Belt with Tree Grate This should be applied in commercial and mixed use areas with moderate to high pedestrian activity, frequent restaurant/ retail destinations, and adjacent to loading zones. This may also be used for street types with a preferred Tree Belt/Furnishing Zone dimension of 8', but where the preferred or minimum dimensions for other Pedestrian Zone elements cannot be met due to encroachments or other constraints. This may be installed adjacent to a Buffer Zone or a Protected Bike Facility at the sidewalk grade, such as the block of Main Street adjacent to City Hall Park. Tree roots in this condition are protected by tree grates, and tree trunks by tree guards. Tree grates are typically 16' long, and flush with other pavements. Only large tree species are appropriate in this condition. See additional tree planting details in "Tree Planting at Tree Grate" on page 784.

Downtown Street Design Standards DRAFT November 2017 City of Burlington 189 Roadway Zone Street Ecology: Stormwater PERVIOUS PAVERS IN PARKING ZONE (PILOT) Parking zones are excellent applications for interlocking concrete pervious paver systems. Many interlocking concrete unit pavers are designed specifically for stormwater management applications. They allow water to pass through joint gaps that are filled with small aggregates and infiltrate into a thick gravel subgrade. This system is widely applicable to both small and large paving applications and it offers the flexibility to be repaired because small sections can be removed and replaced. Interlocking concrete unit pavers offer flexibility in color, style, joint configuration, and paving pattern. It is important to note that selected pervious joint pavers along pedestrian areas must be ADA-compliant and not cause tripping hazards. When installing pervious joint pavers, care should be taken to assure that the base and subgrade is properly constructed to minimize the potential for differential settlement. Regular vacuum cleaning of the paverjoints will help prevent clogging and extend the longevity of the system. Pervious paving within the parking zones of streets can be combined with other curb zone landscape stormwater treatments such as stormwater curb extensions and green gutters to maximize the potential for stormwater management. Key Design Considerations This treatment should be piloted in alleys or on low volume streets before applying this treatment broadly throughout downtown. This treatment may only be applied in consultation with the Department of Public Works until such time it is no longer indicated as a pilot in these standards. Vehicle Loading Requirements Pervious paving systems need to maintain H2O vehicle loading capability. Maximum Gap Between Pavers A''/2" maximum gap is to be maintained between pavers to be ADA compliant. A 1/4" gap is preferred where pedestrians will traverse.

Many interlocking concrete unit pavers are designed specifically for stormwater management applications. They allow water to pass through joint gaps that are filled with small aggregates and infiltrate into a thick gravel subgrade. This system is widely applicable to both small and large paving applications and it offers the flexibility to be repaired because small sections can be removed and replaced. Interlocking concrete unit pavers offer flexibility in color, style, joint configuration, and paving pattern. Along streets that utilize salt in winter conditions, only clay pavers should be used. It is important to note that selected pervious joint pavers along pedestrian areas must be ADA-compliant and not cause tripping hazards. When installing interlocking concrete pavers, care should be taken to assure that the base and subgrade is properly constructed to minimize the potential for differential settlement. It is important to design the pervious paver system sub -base to allow for the infiltration of stormwater, but also be able to consistently support the weight of occasional emergency and/or heavy duty utility vehicles traversing its surface and not allow pavers to buckle over time. Regular vacuum cleaning of the paver joints will help prevent clogging and extend the longevity of the system. In addition, periodic replenishment of the joints with fill sand/stones will help maintain structural stability over time. Pervious paving within the tree belt zones of streets can be combined with other sidewalk landscape stormwater treatments such as stormwater planters and tree grate stormwater planters to maximize the potential for stormwater management.
