ODVA Special Nursing Facility - Roseburg Landscape Narrative Schematic Design

GENERAL SITE DESIGN DESCRIPTION

The site exists within the current ODVA medical facility, just north of River Front Park in the City of Roseburg.

The general site boundaries are as follows: Interstate 5 (East), River Front Park/Roseburg National Cemetery (South), and established survey boundaries (North and West). The project site will connect to the existing rights-of-way within the ODVA facility. The project will consist of redeveloping existing vacant land into a living facility for veterans with various needs and levels of required care.

There are four main building clusters, or “neighborhoods” (Alpha, Bravo, Charlie, Delta), each of which contain three (3) “houses” for residents and staff. The neighborhoods are linked by both external and internal circulation routes. Central to these neighborhoods sits a fifth building, the Community Center that acts as the heart of the entire residence. The associated site includes the following landscape areas and are described in detail below: Main Front Entry Arrival Plaza, Neighborhood Entry Courtyard, Shared Active Courtyard, Community Plaza, Perimeter Landscapes, and Special Activity Zones. The landscape as a whole is intended to support the indoor facility functions by providing an exterior landscape that allows guests, visiting families and care providers to actively and passively pursue enjoyment of life.

GENERAL PLANTING AND IRRIGATION CONCEPT

All plantings will consist of a mix of evergreen and deciduous native and/or site-appropriate plantings that are drought-tolerant upon establishment and require low levels of maintenance. All plant beds abutting site lighting will utilize a 12” wide concrete mowstrip to better distinguish the boundary edge and enable easier mowing maintenance. Lawns will be seeded with a fescue mix seed. These are the main landscape types anticipated:

• Lawn – Meadow/Savannah: Seed mix inspired by the native understory plantings of Oregon White Oak savannahs. These large landscape areas seek to provide visual beauty as well as weave the site into its surrounding ecosystem. Intent for irrigated areas using this seed type to require minimal/seasonal mowing maintenance. Minimum imported top soil depth to be 9”.

• Lawn – Finish Lawn: Traditional lawn aesthetic achieved with low water need fescue seed mix.

Finish lawns shall have a minimum imported topsoil depth of 9”.

• Planting Area/Plant Beds: All plant beds shall have a minimum imported topsoil depth of 18” with 3” compost amendment. All plant beds will have 3” minimum depth bark mulch. Tree plantings at parking lots to be 1.5” caliper minimum.

• Synthetic Turf: All synthetic turf areas to utilize non-rubber fill turf options.

• Stormwater Plant Beds: These areas will have a minimum 18” topsoil. Rock mulch will be 1-1/2” round river rock and installed at a 3” minimum depth. In addition to varying sizes of vegetation, three different sizes of accent stones (round river boulders) are used within the stormwater areas –

PRELIMINARY DRAFT

ODVA Special Nursing Facility May 29, 2025 Schematic Design Site and Landscape Narrative

Small (12-18” diameter), Medium (18-24” diameter), and Large (24-36” diameter). For every 200 square feet of stormwater facility, there are (2) large, (3) medium and (5) small boulders. All boulders should be single-sourced from the Willamette or Umpqua Valley. All site stormwater will be designed and dealt with to the standards by the Authority Having Jurisdiction.

All proposed plant beds and lawns will be irrigated by a permanent, automatically controlled underground sprinkler system. System service connection will be stubbed off from incoming service line for the new building. The irrigation system will be designed and constructed to be as efficient as possible in terms of water usage. It will be centrally controlled using an appropriately sized controller with a network communication devise - An ethernet connection is required. All lawn and landscape areas will have full head to head coverage. Rotor heads will be used at large lawn and meadow areas. Spray heads will be used at all plant beds. Irrigation heads to have check valves to prevent low head drainage and pressure regulation. All zone control valves to have pressure regulation devices. A new backflow preventer, Master Valve, and Flow Sensor will be installed. Master Valve and Flow Sensor will be sized to match the mainline.

All piping to be Schedule 40, including irrigation sleeves under all pavements

MAIN FRONT ENTRY ARRIVAL PLAZA

The entry plaza serves as the primary point of arrival for visitors and residents. It is programmed to have a curbless pick-up/drop-off area for both vehicles and small transit buses separate from main vehicular circulation. Asphalt roadway in the main circulation areas will transition to concrete in the main drop-off/pick-up area. Lighted bollards (assume nine total) and tactile pavers are located at the edge between vehicular and pedestrian areas to meet safety and accessibility requirements. The landscape character in this area is more formal than the surrounding landscape in order to enhance the sense of arrival and accent the proposed building. Foundation plantings will consist of both deciduous and evergreen climate-appropriate plants and trees with purposeful flowering perennials. (4-5) benches, (3) large flag poles, and (2-3) moveable tables with chairs are located within the main plaza.

The vehicular circulation forms a large pedestrian island that includes a memorial space at the center, as well as large trees to provide a visual backdrop along the main sightline from the building. Concrete paths connect to crosswalks that connect to the adjacent site circulation paths. Assume there will be (1) main entry signage feature and up to (2) benches in this space.

In the northern portion of the main entry plaza, a memorial garden pays tribute to veterans of each military branch and provides a quiet place of reflection for guests and residents alike. A large tree in the center of space provides natural shade and shelter. The surrounding landscape consists of both foundation shrub plantings as well as a bridge crossing a large natural stormwater feature. Assume there will be (2-3) moveable tables with chairs and (5) memorial installations.

NEIGHBORHOOD ENTRY COURTYARD / “FRONT PORCH”

There is one Neighborhood Entry Courtyard each for Alpha, Bravo, and Charlie Neighborhoods in the form of a garden space that serves as the exterior foyer for residents and their guests coming to/from each neighborhood. While these are not the main pedestrian entry into the facility, these Neighborhood Entry Courtyards have a landscape design that considers these the main access points for most residents coming to and from. The planting consists of larger shade trees, small accent trees, foundation shrub planting, and small lawn areas at the entrance to the space. At the building entrance, the landscape beds are located in a way that ensures sightlines from the building interior are focused on landscape/trees and not the parking lot beyond. Assume some moveable tables/chairs and up to (2) benches adjacent to building entries.

Adequate pathway lighting guide visitors and residents to/from the site to the building entry. Art elements can be located at the entry to the courtyard as a form of visual wayfinding.

SHARED ACTIVE COURTYARD / “BACK PORCH”

These outdoor areas serve as an exterior extension of the interior residential spaces. Site furnishings in these garden spaces include up to (2) gas-powered barbeques, (1-2) outdoor cushioned couch(s), (4-5) cushioned chairs, (1) outdoor coffee table, (1) picnic table with ADA access, and up to (3) moveable tables and chairs with umbrellas. There are two main landscape rooms connected by an 8’ wide concrete walking path. The larger of the two gathering spaces is immediately adjacent to the building entry/exit. The smaller of the two gathering areas is located further away from the building and is partially enclosed by planting areas. The walking path circumnavigates a large tree at the center of the space that provides visual buffering and shade.

Planting areas in the Shared Active Courtyards take into consideration screening residences from the courtyards, buffering courtyards from site circulation routes, and exterior views into the courtyard from each residence. The Shared Active Courtyards at Alpha and Bravo neighborhoods also incorporate stormwater facilities into their landscape design.

SECURE COURTYARDS - DELTA

The garden spaces provided within the secured Delta facility have been designed in accordance with the Oregon Health Authority Facility Memory Care Community guidelines (OAR 411-057-0170). This means that all concrete paving will have a darker integral color and medium to dark reflective value. Pavement edges to be provided different surface texture (sanded or acid washed finish) to attain a visibly different identifier to the pavement edge, while maintaining the dark integral color/reflective value. Assume each courtyard contains (5) benches, (3) moveable tables/chairs, and at least one (3’x6’) raised garden bed. The landscape areas are designed to create a green buffer between the building and courtyard spaces and define the edges of a meandering loop walking path. Both medium sized and small specimen trees are located in the center landscape island and perimeter planting, respectively. There is a 6’-8’ tall fence/wall (see Architecture) dividing the two south courtyards. This fence is intended to provide a physical and visual barrier between the two courtyards.

NORTH COMMUNITY PLAZA / “PATIO”

The North Community Patio area is intended to host seasonal outdoor events, as well as day-to-day resident activities. To enhance the feeling of a “community backyard”, the landscape design features up to (3) barbeques, a large wheelchair accessible swing, up to (7) moveable tables/chairs with umbrellas, and concrete hardscape open space for large events. A modest size shade pergola shades users from inclement weather and provides the opportunity for year-round use. Amenity spaces include a synthetic turf putting green, raised garden beds, large circular fire pit, and a small physical fitness station at the perimeter. There are programmed spaces for fire pits, adequate accessible seating, raised garden beds, outdoor movie events. Mounded landscape beds and large canopy trees at the perimeter of the space help to insulate the plaza from adjacent parking and foot traffic. Small pathway lighting as well as taller light posts guide residents and users through the plaza and connecting walkways.

SOUTH COMMUNITY PLAZA / PATIO

The South Community Plaza serves as an additional large outdoor space for seasonal and daily use immediately adjacent to the Community Center. As such, moveable tables and chairs are located close to the main building doors and provide an indoor/outdoor dining area for residents. The center of the plaza is a large hardscaped flexible space that serves different functions depending on the season or programmed event needs. Shade sails are attached to large posts and provide shade in the summer, but can be removed for events, if necessary. The posts also provide an attachment point for outdoor movie screens. At the north end of the plaza, there is space for up to (9) raised garden beds and a 10’x10’ garden shed. Along the west edge of the plaza, a small path leads users to an area surrounded by landscape that can be used for bocce ball, chess/checker boards, connect-four, and other group activities. Similar to the North Community Patio, perimeter planting beds are slightly mounded and trees are located to buffer from the storage facility across the roadway. A bus shelter/structure is proposed to be located next to the bus drop-off/pick-up location at the south end of the plaza. A large existing oak tree is intended to be preserved and incorporated into a landscape bed near the bus shelter.

PERIMETER LANDSCAPES

South Vehicle Entry / Savannah Meandering concrete pedestrian paths guide users through a garden space planted with native meadow flowers, grasses, and large Oregon Oak trees. Secondary paths lead to a circular memorial garden near the center of the meadow. Assume up to (7) benches are located along the walking paths and memorial space and pedestrian-rated concrete paths throughout. Opportunity exists for this area to house possible public art funded through this project.

Eastern Perimeter Landscape The main function of the landscape plantings along the eastern edge of the site is to buffer from the noise of I-5, but also to tie the site into its surrounding Oak savannah context. Slopes are planted with a seed mix of native oak savannah understory grasses and perennials. Also, deciduous oak trees are proposed dot the hillside and provide visual screening from within the building and around the interior of the site. Adding to the visual and auditory screening, evergreen trees, in groups of three (3), are planted in front of small retaining walls along the roadway.

Western Perimeter Landscape The landscape areas along the western edge represent a lower level of landscape investment due to the nature of this area eventually connecting to new construction immediately to the west. However, the landscape follows the same “language” of the rest of the parking lot landscape in the form of small and medium-height shrubs and a mix of deciduous and evergreen trees for visual buffering. (3) evergreen trees are strategically located at the visual terminus from inside the main entrance to the west.

SPECIAL ACTIVITY ZONES

Outdoor Physical Therapy Activity Area The outdoor physical therapy activity area on the east side of the Community Center building offers an outdoor extension of useable space for various PT needs. Strategically located plant beds provide the necessary physical barrier to adjacent parking and pathways. Hardscape materials are yet to be determined, but could include concrete, soft surface pavement, and/or synthetic turf/surfacing.

Path(s) of Honor The Path(s) of Honor is/are designated route(s) for celebration of life ceremony. Residents and staff have the opportunity to attend these events, and therefore space is offered for seating and covered shelter along the route(s). The Path(s) of Honor also incorporate interior spaces that terminate in an exterior space large enough to accommodate a small group to witness the flag folding ceremony and transfer to vehicle (North Community Patio and/or South Community Patio).

PEDESTRIAN CIRCULATION

Guests and residents are provided the opportunity to circulate the exterior of the site via concrete paths that connect to the different neighborhood entrances (“front porches”), shared active courtyards (”back porches), community plazas and parking areas. There is a hierarchy of paths that have appropriate widths and turn radii and accommodate two-way motorized scooter traffic. Circulation paths and patio edges have visible

(ex. contrasting color) and tactile treatments (ex. sandblast finish) to delineate edges and improve pedestrian safety. Secondary circulation routes also provide access to/from courtyards and parking areas, as well as provide emergency egress from the neighborhood buildings. Circulation paths are intended to be concrete and will be designed to meet findings from Geotechnical Report. Assume 4” thick cast-in-place concrete for all site walkways. 8” thick vehicular-rated concrete to be used in all vehicle use areas that require service and emergency vehicle access.

ART / MEMORIALS / LANDMARKS

Multiple styles and forms of art are incorporated into site landscape areas to meet minimum art requirements for the site. In specific locations, memorials are designed to commemorate and celebrate US Military branches, historic events, and influential members critical to the history of the US Military and it’s veterans affairs. These memorials are strategically located in areas of arrival as wayfinding elements, moments of reflection in contemplative garden spaces, and along the proposed Path(s) of Honor.

VEHICULAR SITE ACCESS

The site design includes a main road encircling the site that will accommodate two-way vehicular traffic, delivery vehicles, emergency vehicles, maintenance vehicles, shuttles/buses, and visitor/residence parking on both sides of the street. Resident shuttle bus drop-off/pick-up is located in the southeast corner of the South Community Patio along the loop road. Visitors are able to access the site from either the north or south vehicular entry and proceed to neighborhood parking or the Main Front Entry Arrival Plaza for drop-off/pick-up.

STORMWATER MANAGEMENT

In coordination with the project’s civil engineer and client, Cameron McCarthy will create a site-wide stormwater management solution consisting of on-site vegetated stormwater facilities. The stormwater areas will be designed to fit seamlessly into the overall landscape design aesthetic with the use of riparian plant species and accent boulders.
