The purpose of this assessment report is to document the existing conditions of the home, studio, and garden and to make general recommendations for the restoration of the same, considering programmatic needs and following the guidelines set forth in the Secretary of the Interior’s Standards for the Treatment of Historic Properties. Charles and Angie Umlauf purchased their home in 1944. The original structure dates to the late 1920s, and was a one-story, gable-roof structure with limestone walls, a wood-framed pier-and-beam floors and wood roof structure. In 1950, Charles built a studio approximately 100 feet to the east of the house. The studio is a single- story, shed roof structure with slab-on-grade foundation, wood framed walls with wood siding and wood framed roof. In 1956, the Umlauf’s engaged Jessen, Jessen, Millhouse & Greeven to design an addition to enlarge the house. The addition built upon the original stone structure, creating an L-shaped plan with three bedrooms on the main level and a lower level with an additional bedroom, bathroom, and mechanical room. The renovation produced a minimalist aesthetic typical of mid-century, modern design. HISTORIC PRESERVATION | 112 UMLAUF HPEU PLANSecretary of the Interior’s Standards Preservation The Secretary of the Interior’s Standards for the Treatment of Historic Properties is the professional standard for the preservation of historic buildings, structures, sites, objects, and districts, established by the Secretary of the Interior under the National Historic Preservation Act. The Standards develop four treatments for addressing historic properties: preservation, restoration, rehabilitation, and reconstruction. The Standards include Guidelines for Preserving, Rehabilitating, Restoring, and Reconstructing Historic Buildings. These Guidelines contain baseline consistencies with specific direction for each treatment approach. Preservation is defined as the act or process of applying measures necessary to sustain the existing form, integrity, and materials of a historic property as it has evolved over time. Work, including preliminary measures to protect and stabilize the property, generally focuses upon the ongoing maintenance and repair of historic materials and features rather than extensive replacement and new construction. The limited and sensitive upgrading of mechanical, electrical, and plumbing systems and other code-required work to make properties functional is appropriate within a preservation project. However, new exterior additions are not within the scope of this treatment. The Standards for Preservation require retention of the greatest amount of historic fabric along with the building’s historic form. Standards for Preservation: 1. A property will be used as it was historically, or be given a new use that maximizes the retention of distinctive materials, features, spac and spatial relationships. Where a treatment and use have not been identified, a property will be protected and, if necessary, stabilized until additional work may be undertaken. 2. The historic character of a property will be retained and preserved. The replacement of intact or repairable historic materials or alteration of features, spaces, and spatial relationships that characterize a property will be avoided. 3. Each property will be recognized as a physical record of its time, place, and use. Work needed to stabilize, consolidate, and conserve existing historic materials and features will be physically and visually compatible, identifiable upon close inspection, and properly documented for future research. 4. Changes to a property that have acquired historic significance in their own right will be retained and preserved. 5. Distinctive materials, features, finishes, and construction techniques or examples of craftsmanship that characterize a property will be preserved. 6. The existing condition of historic features will be evaluated to determine the appropriate level of intervention needed. Where the severity of deterioration requires repair or limited replacement of a distinctive feature, the new material will match the old in composition, design, color, and texture. 7. Chemical or physical treatments, if appropriate, will be undertaken using the gentlest means possible. Treatments that cause damage to historic materials will not be used. 8. Archaeological resources will be protected and preserved in place. If such resources must be disturbed, mitigation measures will be undertaken.

The limited and sensitive upgrading of mechanical, electrical, and plumbing systems and other code-required work to make properties functional is appropriate within a restoration project. The Restoration Standards allow for the depiction of a building at a particular time in its history by preserving materials, features, finishes, and spaces from its period of significance and removing those from other periods. techniques or examples of craftsmanship that characterize the restoration period will be preserved. 6. Deteriorated features from the restoration period will be repaired rather than replaced. Where the severity of deterioration requires replacement of a distinctive feature, the new feature will match the old in design, color, texture, and, where possible, materials. 7. Replacement of missing features from the restoration period will be substantiated by documentary and physical evidence. A false sense of history will not be created by adding conjectural features, features from other properties, or by combining features that never existed together historically. Standards for Restoration 1. A property will be used as it was historically or be given a new use that interprets the property and its restoration period. 8. Chemical or physical treatments, if appropriate, will be undertaken using the gentlest means possible. Treatments that cause damage to historic materials will not be used. 9. Archaeological resources affected by a project will be protected and preserved in place. If such resources must be disturbed, mitigation measures will be undertaken. 10. Designs that were never executed historically will not be constructed. 2. Materials and features from the restoration period will be retained and preserved. The removal of materials or alteration of features, spaces, and spatial relationships that characterize the period will not be undertaken. 3. Each property will be recognized as a physical record of its time, place, and use. Work needed to stabilize, consolidate and conserve materials and features from the restoration period will be physically and visually compatible, identifiable upon close inspection, and properly documented for future research. 4. Materials, features, spaces and finishes that characterize other historical periods will be documented prior to their alteration or removal. 5.

The Rehabilitation Standards acknowledge the need to alter or add to a historic building to meet continuing or new uses while retaining the building’s historic character building’s historic form. Standards for Rehabilitation 1. A property will be used as it was historically or be given a new use that requires minimal change to its distinctive materials, features, spaces, and spatial relationships. 2. The historic character of a property will be retained and preserved. The removal of distinctive materials or alteration of features, spaces, and spatial relationships that characterize a property will be avoided. replacement of a distinctive feature, the new feature will match the old in design, color, texture, and, where possible, materials. Replacement of missing features will be substantiated by documentary and physical evidence. 7. Chemical or physical treatments, if appropriate, will be undertaken using the gentlest means possible. Treatments that cause damage to historic materials will not be used. 8. Archaeological resources will be protected and preserved in place. If such resources must be disturbed, mitigation measures will be undertaken. 9. New additions, exterior alterations, or related new construction will not destroy historic materials, features, and spatial relationships that characterize the property. The new work will be differentiated from the old and will be compatible with the historic materials, features, size, scale and proportion, and massing to protect the integrity of the property and its environment. 3. Each property will be recognized as a physical record of its time, place, and use. Changes that create a false sense of historical development, such as adding conjectural features or elements from other historic properties, will not be undertaken. 10. New additions and adjacent or related new construction will be undertaken in such a manner that, if removed in the future, the essential form and integrity of the historic property and its environment would be unimpaired. 4. Changes to a property that have acquired historic significance in their own right will be retained and preserved. 5. Distinctive materials, features, finishes, and construction techniques or examples of craftsmanship that characterize a property will be preserved. 6.

A reconstruction will be clearly identified as a contemporary re-creation. 6. Designs that were never executed historically will not be constructed. Note: Reconstruction is not proposed as an approach for treating the historic Umlauf home, studio, or garden. This information is provided as reference only as a component of the secretary of the interior’s standards. Secretary of the Interior’s Standards Reconstruction Reconstruction is defined by the Secretary of the Interior’s Standards as the act or process of depicting, by means of new construction, the form, features, and detailing of a non- surviving site, landscape, building, structure, or object for the purpose of replicating its appearance at a specific period of time and in its historic location. The Reconstruction Standards establish a limited framework for recreating a vanished or non-surviving building with new materials, primarily for interpretive purposes. Standards for Reconstruction 1. Reconstruction will be used to depict vanished or non- surviving portions of a property when documentary and physical evidence is available to permit accurate reconstruction with minimal conjecture and such reconstruction is essential to the public understanding of the property. 2. Reconstruction of a landscape, building, structure or object in its historic location will be preceded by a thorough archaeological investigation to identify and evaluate those features and artifacts which are essential to an accurate reconstruction. If such resources must be disturbed, mitigation measures will be undertaken. 3. Reconstruction will include measures to preserve any remaining historic materials, features, and spatial relationships. 4. Reconstruction will be based on the accurate duplication of historic features and elements substantiated by documentary or physical evidence rather than on conjectural designs or the availability of different features from other historic properties. A reconstructed property will re-create the appearance of the non-surviving historic property in materials, design, color, and texture.

A rich and diverse tree canopy provides an audible and visual buffer from the surrounding urban setting. These canopies are also home to many bird species including song birds, hawks, and owls. The waterfall, creek, and overhead canopy provide a unique and intimate setting for the sculptures and encourages visitors to pause, relax, and reflect on the artist’s message. The proposed landscapes will maintain and enhance this art in nature experience. Three main zones will be represented in the landscape: historic homestead, garden + museum, and natural zone. The historic homestead will complement the surrounding neighborhood with lawn space and border planting to define spaces for gatherings and events, buffer planting to screen views from surrounding properties, and direct lines of sight to Angie’s garden and downtown. The garden + museum zone will maintain existing natural aesthetic and utilize a signature plant pallet to diversify species, enhance visual interest, and manage water on site. The natural zone will increase plant diversity to provide food sources for wildlife, capture and reduce water runoff, provide educational opportunities. Historic Homestead Garden + Museum, Water Management Edge Treatment Natural Area Planting Strategies LANDSCAPE | 123 UMLAUF HPEU PLANHome Welcome garden in circular drive Studio Landscape Zones Historic Homestead The design concept for the historic homestead landscape zone prioritizes a formal layout, integrating open lawns, strategically positioned to serve as inviting gathering spaces. Emphasizing cohesion and continuity, this area seamlessly incorporates planting beds that artfully connect visitors to the life and works of Charles Umlauf. The landscape along Barton Boulevard will maintain existing retaining walls that are reminiscent of the artists time living in the neighborhood with new diversified planting, or designed plant community, to provide a visual cue of entrance to this special place. The added layers of planting provide additional screening to buffer views to surrounding properties. Vehicular circulation should be limited to deliveries, staff parking, and accessible parking for events. The existing entry from Barton Boulevard will remain in its current location to maintain required distance from intersections for queuing vehicles into the site. Large trees define areas and create a ceiling for potential event spaces around the treehouse, home, and studio.

This could be achieved through the addition of plantings, low walls, or other hardscape elements, serving to announce visitors’ arrival while safeguarding the area from vehicular access. Charles Umlauf collaborated with local quarries to fashion plinths for sculptures in this garden, which should now undergo renovation. Additionally, new plinths may be designed to accommodate future sculpture additions, maintaining consistency with the site’s overall hardscape aesthetic. Event spaces for small outdoor gatherings are located near the entrances of existing and proposed structures. A grant- funded renovation of the retaining wall adjacent to the carport on the southern end of the home could provide an elevated vantage point overlooking the garden below, and creating a space for events. Another smaller event space located between the studio and the circular drive, featuring a lawn bordered by hardscape elements, could serve as an area for seating or temporary exhibits. An intimate stone patio nestled between the home and studio boasts a fountain and planter, offering stunning views of downtown. Rehabilitation of this space is recommended, including updates to walking surfaces, utility lines, pond and plant beds, and the addition of a new railing or wall to ensure safety. Moreover, the plan suggests conducting a detailed analysis of fire truck maneuverability and parking options for the A upper driveway if vehicular access is desired at this level (see initial vehicle tracking exhibit in appendix).

Rain fall is intercepted by the extensive tree canopy, but limited ground plantings and the shear volume of water flowing on to the site erodes soils, damages existing walkways in the garden, and floods the sculptures, which may damage existing plinths and footings. Several strategies are recommended to address excess water running on to and through the site including detention ponds at the top of slopes, green mulch or multi-layered planting on slopes, swales and rain gardens at the bottom of slopes to direct water to key locations, and improvements to the existing pond for additional detention capacity. Rainfall, direction of flow Direction of water flow Runoff Piped to biofilter (swale, raingarden) Curb and gutter to capture, direct runoff, and provide first filter Pond - Permanent Pool may be reduced during times of drought Rain Garden - Vegetated Detention Open Swale or Underdrain Pipe Green Mulch Gathering Space for Events and Education with integrated Creek Bed Existing Pond with decresed permanent pool Terraced detention pond or rain garden Existing Pond Existing Stormwater Infrastructure LANDSCAPE | 127 UMLAUF HPEU PLANLandscape Zones Sculpture Garden + Museum, Water Management Water may be diverted from entering the site with the addition of a curb and gutter along Barton Boulevard, which is currently outside the property boundaries of the site. At the top of the slope within the property boundary, detention ponds with retaining walls located on the downhill side will capture and filter runoff from the road and the adjacent neighborhood for decreased erosion and trail damage while improving the quality of water that enters the garden. A primary planting strategy for the entire site will increase the diversity of plant species and add layers of planting. There are three levels of planting, including groundcovers, mid-level, and tree canopy. Groundcover, plants and vines that hug the ground, creates a green mulch that protects roots through extreme temperatures, holds moisture in the soil, intercepts or slows rain from falling on soil, captures water in the root system to be released through evapotranspiration, filters nutrients and toxins to improve water quality, provides food and nesting material for wildlife, and provides color and texture to arouse visitor’s interest and enjoyment of the gardens. Mid-level planting includes shrubs and perennials that add texture and color at eye level and may provide backgrounds for sculptures located along the slope. These plants also capture water and provide shelter and food for wildlife. EXISTING CONDITIONS with ground cover and trees PROPOSED DIVERSIFIED LANDSCAPE with enhanced ground cover, shrubs, and mid-level planting LANDSCAPE | 128 UMLAUF HPEU PLANLandscape Zones Sculpture Garden + Museum, Water Management Trails may be edged by swales to capture water running from the existing slope and direct water to the pond. Think of swales as shallow, lineal depressions that create a trail system for water, nutrients, leaves, and other debris to travel and collect at key locations. These collection areas can be used as educational opportunities to see what flows downhill, monitor water quality, and collect seeds, leaves, and other natural objects that may be used for inspiration in sketches, sculpture, poems, and other art forms. Swales may be vegetated as a bioswale, resemble creek beds with rock bottoms, or incorporate a combination of rock and planting. Natural edges are typical for the site but formal edges may be appropriate for some exhibits or near proposed buildings to connect the interior and exterior spaces. For linear walkways, plants may be encouraged to grow over the path to soften the edges. Swales may be enlarged in areas to create rain gardens that slow down water flow through the site and hold additional volume of water to reduce the amount of water entering the pond during rain events. Rain gardens provide additional filtration for improved water quality and also allow water to infiltrate into the ground for increased water volumes to local aquifers.

The plan recommends treating the site’s edges to create a more welcoming experience for visitors, make the UMLAUF more visible, and enhance the experience for people walking/wheeling around the site. The walking, wheeling, and vehicular entry will be well defined and visible, while the sculptures in the welcome zone will provide a glimpse of Umlauf’s work and begin the visitors interpretive experience. To soften the appearance of the edge along Azie Morton Road, the plan proposes a new wall with a garden aesthetic. Made of metallic fence and a lower stone wall with pockets of planting that frame views into the garden. This new edge may also frame temporary banners for events and exhibitions. Site identification and walking/wheeling improvements at the intersection of Azie Morton Road and Barton Springs Road may be accomplished by replacing the existing retaining walls and relocating them further away from the curb. Dividing the retaining wall into lower and upper tiers with planting bed between will create a formal edge at pedestrian scale. The UMLAUF logo and permanent banner space that is built into the wall will also welcome all who cross through this intersection. Low stone or concrete wall with decorative fence embedded to allow views into garden from Azie Morton Road. Solid portions of wall used for permanent banner space welcomes visitors to the museum and garden with information about programming and exhibits.

The trail or boardwalk will guide visitors through the natural area which may feature temporary exhibits and interpretive signs for outdoor learning. The UMLAUF’s site is a green oasis within an urban area. However, native plant ecosystems have been disrupted by surrounding development over time. To optimize the landscape’s performance in water management, habitat provision, and visual appeal, the selected plant community will comprise both native species and those well-adapted to the local environment. Given the prevalent tree canopy shading much of the site, the proposed plants will primarily thrive in shade conditions. Diversifying plants in the natural zone will offer various benefits, including: • Providing habitat, food and shelter for wildlife • Creating visual interest with colorful flowers, a variety of leaf textures, and fruit bearing plants • Slowing the water run-off and capturing rainfall in the leaf structure Increasing water infiltration through root absorption • • Cleansing soil and water toxins by plant uptake • Providing environmental education by showcasing plants used by people throughout history Trim and limb up branches for clear height of 8’ above walking surface Interpretive signage or temporary exhibit space Enhanced planted adjacent to trail at interpretive or exhibit areas Mowed or managed edge along trail, 18”-36” width section along trail with mowed and some beds near seating/viewing opps LANDSCAPE | 133 UMLAUF HPEU PLANEcology + Biodiversity The UMLAUF site is intricately connected to Austin’s broader ecosystem, its ecology and biodiversity ebb and flow into the surrounding sites. It also represents a site of natural respite for Austin residents, providing moments of tranquility and joy as they immerse themselves in the garden. In an effort to preserve the ecological balance and biodiversity of the area, the landscape efforts are primarily focused on three key objectives: removing invasive species, revitalizing mid-level vegetation, and enhancing plant diversity onsite. By undertaking these initiatives, the plan aims to uphold the integrity of the ecosystem and honor the diverse array of plant life that once thrived on this land before the establishment of site boundaries. “What a beautiful place. I am a native Austinite who believes in the importance of nature, community, public education and art for all. I hope we can continue to nurture this place and all of our other parks and art facilities with the unified goal of environmental stewardship, community, inclusivity, and art.” Site Plan Sketch of Areas to be Replenished LANDSCAPE | 134 UMLAUF HPEU PLANGreen Mulch, Groundcovers Recommendations Achillea millefolium (Yarrow): pollinator plant, historic medicinal and cultural use, soil remediation Ipomopsis rubra (Standing Cypress): pollinator plant Lobelia cardinalis (Cardinal Flower): pollinator plant, historic medicinal and cultural use Andropogon ternarius (Splitbeard Bluestem): nesting material, pollinator plant, soil remediation Bouteloua curtipendula (Sideoats Grama): nesting material and food/seeds, soil remediation Calyptocarpus vialis (Horseherb): pollinator plant Monarda fistulosa (Wild Bee Balm): pollinator plant, historic medicinal and cultural use Rivina humilis (Pigeonberry): wildlife food Echinacea purpurea (Purple Coneflower): pollinator plant, historic medicinal and cultural use, soil remediator Chasmanthium latifolium (Inland Sea Oats): pollinator plant, nesting material and food/seeds Elymus canadensis (Prairie Wildrye): pollinator plant, habitat food Viola Ordorata (Sweet Violet): historic medicinal and cultural use Source: www.wildflower.org/ LANDSCAPE | 135 UMLAUF HPEU PLAN
