Gibran Lule-Hurtado* National Parks Service *Working Group Members from the National Parks Service Letter From the Community Working Group Williamson Creek is a gem crossing West to East in South Austin between Oak Hill and McKinney Falls State Park. Residents of the neighborhoods surrounding Williamson Creek have enjoyed this natural beauty for more than 20 years. Community efforts over a number of years, including trash pick-ups, tree planting and the removal of invasive species, have resulted in improving the health of the creek and supporting the native flora and fauna. Central Williamson Creek Greenway is slowly becoming a more welcoming green space for residents to connect with nature and for nature to thrive. We are thrilled to envision the future of a place we love so dearly with the Central Williamson Creek Greenway Vision Plan. This Vision Plan represents a 12-month process of both Williamson Creek Working Group (WCWG) formal and creative efforts to engage the community and input derived from public engagement. Community engagement activities included: community members recording their own oral histories through WCWG interviews; virtual community picnics virtual mapping enabling community to propose ideas such as food forest planting and hiking trails in and around the creek; several in-person and socially-distanced “Creek Chats” to engage the community; and a final community picnic to unveil the Vision Plan and offer an opportunity to provide community feedback in 2021. Implementation of the community’s spirited ideas for this plan, in part or entirety, will transform Central Williamson Creek Greenway from its current state to one that will serve nature and the community in the future. Next steps in this process include: reviewing a final Vision Plan following the consideration of all community comments; presenting this plan to the Environmental Commission and the Parks and Recreation Board; scheduling 2021 Creek Cleanup work days; coordinating invasive species identification and removal; tree planting; identifying funding opportunities to implement the plan; creating the Williamson Creek Hiking Club; and constructing the Williamson Creek Community Labyrinth to increase community activity and overall health. Thank you to the St. David’s Foundation for providing the grant used to draft this Vision Plan, to Community Powered Workshop for facilitating the process, and to Asakura Robinson for co-creating this Vision Plan with us. We also want to thank members of the City of Austin Working Group for their dedication and time. We are excited to move forward with the support of Austin Parks & Recreation and Watershed Protection Departments and their affiliates. Lastly, we would like to thank and acknowledge those longtime friends who have supported and participated in efforts to maintain Williamson Creek since 2005.

Community Powered Workshop (CPW) Community Powered Workshop is an Austin-based non-profit architecture and planning organization that works alongside communities to create powerful and equitable places that promote a healthy future and break barriers of systemic injustice through collaborative planning, community driven research and social impact design. We entered this community-led effort to create the Central Williamson Creek Vision Plan in 2017 alongside community members in the Central Williamson Creek area to re-imagine this green space as a resilient, healthy and connected public space. For this Vision Planning process, Community Powered Workshop facilitated the convening of a Community Working Group to bring local voices and perspectives to the table, and a City of Austin Working Group composed of staff from multiple City of Austin departments and the National Parks Service. With the goal to build long-term, collaborative working relationships between community members and public land managers, these working groups place community members and City staff on equal footing in the planning process as a way to balance community priorities that also support a sustainable and healthy environment. Moving forward, we will continue collaborating with residents of the neighborhoods and City departments to bring the Central Williamson Creek Greenway Vision Plan to life. 6 7 Central Williamson Creek Vision Greenway Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Greenway Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Greenway Legend Central Williamson Creek is a stretch of nearly continuous greenway along Williamson Creek in Austin, Texas. This section of the creek, which runs for about two miles between S. Congress Avenue and Menchaca Road, and just north of Stassney Lane is located in a primarily residential area of South Austin. Much of the land directly adjacent to the creek is publicly owned by The City of Austin Parks Department and the City of Austin Watershed Protection Department as a result of a floodplain home-buyout project that transitioned formerly residential land into floodable green space. This land now presents a significant opportunity to create a connected recreational greenway for a park-deficient community in South Austin.

Major floods in 1998, 2001, and 2013 prompted a consideration of a buyout program in this area, and in 2015, the first phase of a home buyout program began through a partnership between the City of Austin and the U.S. Army Corps of Engineers. As of 2019, 51 properties have been purchased by the city and demolished to prevent future redevelopment. There are a total of four buyout areas along the project sitealong the project site: the Meadow Creek buyout area, Radham Circle buyout area, the Richmond Tributary buyout area, and the Heartwood buyout area (see map on page 9). The land and floodplain recovered from this effort is now owned and maintained by the City of Austin’s Watershed Protection Department with the goal of maintaining it as an open, floodable space to protect adjoining residences from flooding. Community-Driven Open Space In addition to the home buyout properties, Central Williamson Creek is bordered by about 58 acres of undeveloped parkland owned by the Austin Parks and Recreation Department and 16 acres of residential floodplain buyout properties owned by the Austin Watershed Protection Department. This publicly owned land adjacent to the rich biodiverse riparian ecosystem of Williamson Creek presents a unique opportunity to connect residents of South Austin to urban ecological systems, recreation, and gathering spaces. This opportunity was quickly recognized by residents, and in 2019 community leaders in the Southwood neighborhood partnered with local non-profits and conservation organizations to initiate a series of community engagement and activation events called Explore! Williamson Creek. Many community desires emerged, including the desire for a creekside nature trail, social gathering spaces, community gardens, wildlife habitat, and other amenities. The outcome of these activations highlighted the passion community members hold for Williamson Creek and their desire to have a strong voice in the planning and design process. This vision plan process continues this community- driven effort through an engaged Community Working Group feedback process and a series of Community Workshops. Previous Planning Efforts City of Austin Neighborhood planning documents addressing South Austin acknowledge Williamson Creek as a priority area for parks and recreation. South Austin Combined Neighborhood Plan: Create bike lanes on major roads, provide a greenbelt path along Williamson Creek. Southeast Combined Neighborhood Plan: Add more sidewalks, create hike and bike trail along Williamson Creek, add mixed-use zoning. Southeast Combined Neighborhood Plan: Maintain Williamson Creek in a natural state, improve pedestrian connections, and develop a new neighborhood park. W.

The recommendations in this plan were created through close collaboration with a community working group, the City working group, and feedback from the general public. Chapter 2 | Pages 21-42 Vision Plan The Vision Plan chapter presents the overall designs for the Williamson Creek Greenway from S. Congress Avenue to Menchaca Road, along with examples of more detailed concept designs for two trailheads at Orland St and S. 1st Street and at Meadow Creek Circle. Chapter 3 | Pages 43-76 Developing the Vision This chapter provides a detailed overview of the four community goals that drove this plan, how they were developed, and each goal’s corresponding design strategies utilized in the Vision Plan to achieve those goals. Chapter 4 | Pages 77-84 Community Engagement This Vision Plan was developed in close collaboration with community members, and this chapter provides an overview of the digital and in-person community engagement process and outcomes. Chapter 5 | Pages 85-118 Existing Conditions The Existing Conditions chapter provides an overview of current ecological, hydrological, and social conditions of the creek and its immediate surrounding neighborhood. Chapter 6 | Pages 119-130 Implementation Chapter 6 lays out a three-tiered approach to funding and constructing the Vision Plan designs over time based on project effort and feasibility, and provides maintenance recommendations. Bioswale Rock Berm Restoration Trail Example of Water Quality Strategy along Trail Community Goals The following four goals emerged from a design process that listened to and engaged with community priorities through a series of virtual and in-person engagement events, described later in Chapter 4. 1. A RESTORED, BIODIVERSE GREENWAY The future Central Williamson Creek Greenway will be a healthy, functioning riparian ecosystem, rich with plant and animal life and free from ecologically destructive invasive species. Volunteer and city ecological restoration efforts, green infrastructure installations, and low-impact trails will preserve the creek’s wild character, protect sensitive species, and improve water quality. 2. A COMMUNITY-CENTERED GREENWAY The future Central Williamson Creek Greenway will be a system of trails, parks, community gardens, and other gathering spaces where neighbors and South Austin residents gather to socialize and exercise. Community-built art, urban agriculture, restoration and other projects along the greenway will create a sense of ownership and pride. 3. AN ACCESSIBLE AND VISIBLE GREENWAY The future Central Williamson Creek Greenway will provide a continuous trail from S. Congress Avenue to Menchaca Road through key land acquisition and low-impact trail construction. Visitors to the greenway will be able to orient themselves through clear wayfinding signage, and learn more about the unique history, ecology, and geology of the creek through educational signage. 4. AN ACTIVE AND CONNECTED GREENWAY The future Central Williamson Creek Greenway will be an important public health amenity for the neighborhood and the broader Austin community. It will provide a key east-west connection to South Austin neighborhood resources and public transportation. The trail system will connect all communities to the creek and provide accessible creek experiences for those of all abilities. Mountain biking trails, fitness programming, and community gardens along the trail network will further enhance neighborhood health. 12 13 Central Williamson Creek Vision Greenway Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Greenway Vision Plan MARCH 2021 DRAFTSocial Pinpoint Social Pinpoint was the online virtual community engagement platform utilized to gather ideas and feedback from the general public throughout this project.

The City Working Group was comprised of 11 City of Austin staff members, representing the Parks and Recreation Department, the Watershed Protection Department, and Office of Sustainability, and the Urban Trails program. Two members represented the National Parks Service. 14 15 Central Williamson Creek Vision Greenway Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Greenway Vision Plan MARCH 2021 DRAFTMany of these challenges also present opportunities. Rugged trails can present moments to highlight south Austin’s unique geology. Properties in the floodplain can host green infrastructure and floodplain restoration. Community members can work together to help manage invasive plant species. Each obstacle presents unique opportunities for creativity, teamwork, and stewardship. Opportunities and Constraints Williamson Creek is a rich ecological and social resource with great potential for increased use by local residents. It provides local residents with a green space for recreation, relaxation, and gathering. The Heartwood and Emerald Wood Community Gardens serve as hubs of community activity. Due to the Watershed Protection Department floodplain buyout program, there are many vacant areas that could provide more opportunities to interact with the creek. There are considerations and limitations to increased community access to the creek, however. While PARD and WPD own most of the properties along the creek, some sections are privately owned. This poses challenges to the creation of a continuous east-west trail along the creek. Many city- owned properties, meanwhile, are in the Williamson Creek floodplain. In these areas, site improvements must be low-impact and flood safe. In other areas, the creek’s rugged terrain and steep slopes limit access. Floodplains It should be noted that due to a new precipitation study from the National Weather Service known as Atlas-14, the floodplain maps of the entire city will be re-mapped within the next 3-5 years. The floodplains are shown in this document to reflect an estimation of this future update. It reflects these upcoming changes by showing “estimated” 25 year and 100 year flood events. According to the City of Austin’s FloodPro “Fully Developed Floodplain” scenario that can be found at https://www.austintexas.gov/floodpro/ Heartwood Community Garden is a community gathering space along the greenway where neighbors can grow their own food. 16 17 Central Williamson Creek Vision Greenway Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Greenway Vision Plan MARCH 2021 DRAFTd. a R c a h c n e M Stormwater Outfalls Rimrock Fringe Wetlands Springs Existing Bike Lanes PARD Properties WPD Properties 0 250 500 1,000’ N 18 Opportunities and Constraints Map Opportunities Constraints gress Ave n o S C S 1st St. Central Williamson Creek Greenway Vision Plan MARCH 2021 DRAFT2: Central Williamson Creek Vision Plan 20 21 Central Williamson Creek Vision Greenway Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Greenway Vision Plan MARCH 2021 DRAFTOverall Vision Plan This Vision Plan design for the Central Williamson Creek Greenway provides a conceptual trail and open space designs for the creek and the Parks and Recreation and Watershed Protection Department-owned land along the length of the creek. This overall design details the placement and locations of several design components: 1. Trails Trail Materials Austin’s 2014 Urban Trails Plan identifies Williamson Creek as a Tier 2 trail, indicating that it should be constructed with a paved material. Throughout the community engagement process for this Vision Plan, the community emphasized their desire for natural, low-impact trails along the greenway. This document recommends mulch or bond-mulch trails to align as closely as possible to community desires. However, a City-led preliminary engineering report and corresponding community engagement are zz zrecommended as the next steps in the process to create a balanced approach to trail development. Trail Placement Trail placement along the creek was determined by the following factors: 1. Slope Slope analyses identify changes in elevation in the land. Areas with a shallow slope were prioritized for trail placement because it is difficult for trail users to walk on steep slopes, and creating a trail on steep slopes requires greater ecological disturbance, and potential for erosion. See page 106for a detailed slope analysis. 2. Property Ownership The trail placement runs primarily along City-owned PARD and WPD property; however, there are several locations where land adjacent to the creek is privately owned. This plan recommends acquiring easements in those properties. In the meantime, trail users must walk in the City- owned creek bed during dry weather. After rains, trail users must utilize “high water” trails on sidewalks to avoid trespassing on private property. These high water routes are short detours that quickly reconnect to the greenway trail on City-owned property. 3. Sensitive Ecological Features Central Williamson Creek’s biodiversity and unique geological features are a primary draw for visitors; however, these sensitive natural assets must be protected, and are protected legally through the City of Austin’s environmental restrictions. According to this code, trails can not be placed within a 50’ buffer of a Critical Environmental Feature, which includes seeps, springs, fringe wetlands, and rim rock, without an environmental variance. The placement of the trail along Central Williamson Creek maintains a 50’ distance from these features, unless it is absolutely necessaryto to pass within the buffer zone to provide trail connectivity. 4. Neighborhood Connectivity When considering trail placement, community input on common access points to the creek and identification of existing community assets and resources took high priority. This trail placement identifies a network of access points at key intersections, bridges, neighborhoods, and community resources. 2. Vision Plan Elements Orland Trailhead Creek Idea Cards The Vision Plan Elements, which include features such as signage, community gardens, and community message boards, arose from the Creek Idea Card community engagement process outlined in Chapter 4. This involved the development of 50 Creek Idea cards that were voted up or down in popularity by community members. Both popularity and feasibility were taken into consideration when selecting the final cards to be included in the plan as a Vision Plan Element. Each Element corresponds with one of the four overall goals, which can be identified by their color. See pages 24-25 for a full list of Vision Plan Elements and the goals they support. 3. Example Trailheads Site Selection Detailed conceptual designs for two key trailheads are included in this plan. The purpose of these designs are to show examples of how activated trailheads and community gathering spaces at key nodes along the trail can further social, ecological, and public health goals. These sites were selected based on hydrological, ownership, and social factors. Meadow Creek Trailhead This land is buyout property that is owned by WPD. This site was selected to take advantage of funding offered by the department for ecological restoration and tree planting on buyout property, because it was the largest continuous piece of buyout property and because it straddles both the north and south sides of the creek. This land is owned by PARD. It was chosen as an example trailhead because it is out of the floodplain, and can thus have built structures or other features that would otherwise be destroyed if they were in the floodplain. 4. Environmental Features Ecological Restoration Significant opportunities exist for multiple types of ecological restoration along Williamson Creek: 1. Creek Restoration 2. Woodland Restoration 3. Wildflower Meadows 4. Fringe Wetland Restoration Opportunities for these four types of restoration are located and identified throughout the Overall Vision Plan. The Chapter 6 Implementation Plan outlines how both volunteer efforts and City-led efforts can work in tandem over time to achieve restoration goals. Reclaimed Brush Berms Reclaimed brush berms are neatly stacked piles of fallen branches that provide habitat and cover for small animal species and line paths to improve wayfinding. Stone Berms Stone berms slow rainwater flow before it enters the creek, helping to remove some sediments and other pollutants before it enters the creek. 22 23 Central Williamson Creek Vision Greenway Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Greenway Vision Plan MARCH 2021 DRAFTVision Plan Elements Goal Key These vision plan elements included in this design are a result of the “Creek Cards” community engagement process outlined in Chapters 3 and 4. 1.

This community engagement process is described in greater detail in Chapter 4. Creak Idea Cards “Creek Idea Cards” were used as part of the community engagement process on the digital platform Social Pinpoint and at in-person, socially distanced events to gain an understanding of the types of programs, trails, amenities, and other uses the Community Working Group and general public desired along the trail. These idea cards were organized into four categories, each helping to achieve one of the four main goals of the project. Idea Card Placement The most popular idea cards were selected by the community using a digital voting activity on Social Pinpoint. After this process, the design team placed the cards along the greenway using information from existing conditions, comments on the cards, other community engagement outcomes, and conversations with the Community Working Group.

However, this habitat is threatened by large swaths of invasive species. Floodplain restoration, including the removal of invasive species, and planting of native species, will increase biodiversity. Toolkit Items: Clean-Up Days Wildflower Planting Creek Restoration Pollinator boxes Preserve the creek's wild character Central Williamson Creek Greenway will be kept as natural as possible. This reflects the desires of the neighboring community to have as little impact as possible on the ecology of the creek and to preserve the sense of wilderness in the heart of South Austin. Toolkit Items: Natural Trails Wildflower Planting Creek Restoration Reveal ecology through environmental education experiences Educational experiences along the greenway will facilitate the discovery of the unique ecology, hydrology, and geology of the creek environment. Toolkit Items: Environmental education Outdoor Classroom Balance access with conserving floodplain ecology The trails along Williamson Creek will maintain a safe distance from critical environmental features, such as seeps and springs, fringe wetlands, and rim rock. Low-impact trail materials and interventions will be prioritized.

However, due to the COVID-19 crisis beginning in March 2020 and continuing throughout the entirety of the project, much of this engagement shifted from in-person to online, digital engagement with some outdoor, socially distanced “creekside” events, where participants could pick up a “creekpack” of engagement activities in English and Spanish. These activities could also be mailed to community members upon request. The majority of digital engagement took place using a platform called Social Pinpoint. Virtual Community Working Group and City Working Group meetings were held monthly on Zoom (See schedule on pages 14 - 15). Three public meetings were held on Zoom to demonstrate Social Pinpoint, present designs, and solicit feedback. Community Mapping During the Existing Conditions Phase, community members were asked to use Social Pinpoint to geographically share their ideas, activities, and unique places along the Greenway. Categories included identifying locations for “Unique and Interesting Features,” “Ideas and Suggestions,” “Trailheads,”, and “Challenges.” This online mapping activity was open from July 23rd, 2020 to October 13th, 2020. Toolkit Idea Cards Findings from the Community Greenway Map and outcomes from the Storytelling (see page 91), conversations with the Community Working Group, and other community engagement activities were then used to craft the four primary goals of the Central Williamson Creek Green Vision Plan. 1. A Restored, Biodiverse Greenway 2. A Community-Centered Greenway 3. An Accessible and Visible Greenway 4. An Active and Connected Greenway These four goals guided the development of 52 unique “Creek Idea Cards,” each organized into one of the four goal categories. Community members on the Central Williamson Creek Greenway Social Pinpoint website voted on ideas by adding a thumbs up on ideas they wanted to see at the Greenway or a thumbs down on ideas they did not want to see. After voting closed on November 7th, the design team tabulated the votes, and integrated the highest scoring idea cards into the Vision Plan for the Central Williamson Creek Greenway.

This graphic shows the net score each creek idea card received. Idea cards received one point when they received a “thumbs up” and one negative point when they received a “thumbs down.” The sum of these points produced the net score. Vision Plan- Placement of Creek Idea Cards After the voting period on Social Pinpoint closed, the idea cards were then placed along the Greenway using information gathered from existing conditions, conversations with both the working group, and insights from the initial Social Pinpoint Greenway Mapping Exercise. A conceptual design for the entire greenway, as well as two trailheads at South 1st and Orland streets and Meadow Creek Drive were available for comment until January 18th, 2021. 80 81 Central Williamson Creek Greenway Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Greenway Vision Plan MARCH 2021 DRAFTIn-Person Engagement Due to the COVID-19 crisis, in-person engagement was limited to four “Creek Chats,” where Community Powered Workshop and representatives from the Community Working Groupand representatives from the Community Working Group facilitated an in-person version of the Creek idea card activity. These events were socially distanced and held outdoors at picnic tables along Central Williamson Creek. 82 83 Central Williamson Creek Greenway Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Greenway Vision Plan MARCH 2021 DRAFT5: Existing Conditions 84 Central Williamson Greenway Creek Vision Plan FEBRUARY 2021 DRAFT Central Williamson Creek Greenway Vision Plan FEBRUARY 2021DRAFT 85 Central Williamson Creek provides a peaceful place for people to connect with nature. Community Context Demographics The Central Williamson Creek area is surrounded by about 11,000 residents, mostly living in single-family homes. This is a diverse community both racially and economically. Fifty-one percent of residents are non-white, with 45% of that group identifying as Hispanic/Latinx. Forty- five percent of the neighborhood is low- income and 19% is middle income.1 This area is considered to be socioeconomically vulnerable, with high levels of linguistic isolation and refugees. Community Health According to the Healthy Parks Plan for Travis, Bastrop, and Caldwell Counties, this neighborhood has high rates of adult heart disease, high cholesterol, poor mental health, and prevalence of stroke. These poor health outcomes can be aggravated and compounded by other demographic factors, including the area’s high socioeconomic vulnerability. These are important considerations, as parks are critical public health assets that offer free opportunities to be active. Parks and green space can ease depression and anxiety by providing areas to relax and connect with friends and family. They also cool the surrounding environment and filter out air and water pollutants that can harm health. 1. Low-income is defined as households whose ratio of household income to poverty level was less than 2, calculated from the Census Bureau's American Community Survey. Prior Engagement The Central Williamson Creek Vision Plan expands upon a previous community engagement process that began in 2019 through a collaboration between neighborhood community members, Public Green & Wild, The Nature Conservancy, Community Powered Workshop, and the National Parks Service. Engagement efforts were focused in the Middle Williamson Creek buyout area between Union Pacific Railroad and S. 1st Street. The focus area includes the buyout neighborhoods of Meadow Creek Drive and Radham Circle. The engagement process included four community events as part of a series called Explore! Williamson Creek. Three of these events were “Creek Stomps,” which involved a short overview on the creek’s ecology and hydrology, a guided community hike, and an opportunity for community feedback. The final event invited those who were unable or uninterested in exploring the creek to attend a more traditional focus group format to garner feedback. In addition to these events, the Watershed Protection Department conducted two community feedback surveys at the Richmond Tributary Buyout Area and at Meadow Creek. These surveys were intended to provide feedback to the Watershed Protection Department on how they are currently managing buyout land and how they may manage it in the future to align with community desires. In 2020, the Watershed Protection Department plans on conducting a survey of the Heartwood Buyout area. 87 Milk Snail found along the Greenbelt Photo: Anna Pittala 86 Central Williamson Creek Greenway Vision Plan MARCH 2021DRAFTCentral Williamson Greenway Creek Vision Plan MARCH 2021 DRAFTExplore Williamson Creek!

Local Ecology Williamson Creek stretches across the Environmental Protection Agency’s Level 3 Edwards Plateau and Blackland Prairie Ecological Regions. The Edwards Plateau ecoregion is characterized by thin limestone or granite soils and the Blackland Prairie region has thick clay soils. Each of these characteristic soils host different types of native plants, thus the ecotone2 between these two ecoregions produce conditions that are very biodiverse. These open spaces surrounding the creek are rich with biodiversity due to the alluvial sediments and availability of water, which create favorable conditions for a broad diversity of plant and wildlife species. The past few years have seen a community effort to document local biodiversity in Williamson Creek using iNaturalist, a citizen science phone app that identifies and records plant and animal sightings. Both native and invasive plants have been documented along the creek. Citizen scientists have recorded more than 305 nature observations of more than 171 species within the Central Williamson Creek Greenway. While the most observed wildlife species by citizen scientists include common species such as raccoons, woodpeckers, and fox squirrels, many sightings record less common species such as Barred Owl (Strix varia), Green Heron (Butorides virescens), and American Basketflower (Centaurea americana).

Patches of fringe wetlands, especially near seeps and springs, are scattered throughout floodplain. Many areas along the creek are dominated by invasive woody and herbaceous vegetation, most notably stands of Glossy Privet, Giant Reed, and Chinese Tallow. Areas dominated by invasive species should become high priority areas for invasive species management per the City of Austin Invasive Species Management Plan published in 2012. 1 2 1 2 3 Challenge 1: Balance sensitive ecology with community access and recreation. Challenge 2: Balance invasive species removal with erosion control. Opportunity 1: Educational wildflower meadow pocket parks at buyout areas.

These observations are geolocated and provide researchers with valuable information about the spatial distribution and ecology of plant and animal species. Residents and community members of Williamson Creek have used iNaturalist to document the creek’s biodiversity through both individual initiative and organized community “bio-blitzes.” The map on the right shows the results of these efforts. Wildlife The plant and habitat diversity in Williamson Creek allow for a broad range of fish, amphibian, bird, and mammal species to thrive. iNaturalist and previous field surveys conducted by The Nature Conservancy included spiny softshell turtle, green heron, great blue heron, cedar waxwings, and chimney swift sightings. In September 2018, two wildlife cameras were installed in the Central Williamson Creek Greenway with the Austin Wildlife Watch project and Austin park rangers. These cameras documented deer, raccoons, opossums, and coyotes.

Creek Access Access to the creek itself can be a challenge. Many informal trails and entrances have been created by community members. However, they occur sporadically through the greenway and do not provide a connected path along the entirety of the Central Williamson Creek Greenway. Access to these informal trails are frequently found at the mowed, grassy buyout parcels and under the bridges where S. 1st Street, S. Congress Avenue, and Menchaca Road cross Williamson Creek. Greenway Access Neighborhood Access The neighborhoods along Central Williamson Creek have a robust sidewalk network, creating good pedestrian connectivity for the adjoining neighborhoods. Emerald Forest Drive provides a dedicated bike lane for traveling in the north-south direction, and StassneyLane provides a bike lane for travelling in the east-west direction. In the future, the CAMPO 2035 plan hopes to augment S. Congress Avenue S. 1st Street, and MenchacaRoad to become safe, designated “bike corridors.” In the meantime, the surrounding neighborhood roads of mostly low-traffic residential homes offer a safe alternative to high-traffic thoroughfares like S. Congress Avenue and Menchaca Road. The City of Austin Urban Trail Network is actively working on a plan to develop the abandoned Bergstrom Spur Right-of-Way as an urban trail. The 2014 City of Austin Urban Trails Plan also proposes the creation of additional car-free regional connections via the Williamson Creek Greenway and the Union Pacific right-of- way. Central Williamson Creek is served by the 1, 3, 10, 311, and 801 bus. 102 Creek entrance from the north side of S.

In some areas, the creek’s erosive force has eaten into its banks, exposing steep rock faces dozens of feet tall. Erosion’s effects are less dramatic in other places, but still make it difficult to experience the creek. This map shows the locations of these steep areas, illustrating their relationship to the adjacent street grid and the limitations they place on access to Williamson Creek.

A future hike and bike trail along the creek would provide a safer and more comfortable transportation or exercise route than paved neighborhood streets and sidewalks. Trees and vegetation in the Williamson Creek Floodplain cool the air though a process called “evapotranspiration.” Parking lots and buildings absorb and hold heat, releasing back into the air. Urban temperatures are often unpleasant and dangerous for people.

The section below illustrates where the creek flows underneath S. 1st Street bridge. This area presents an opportunity to provide more formalized access to the creek in the future. Previous Planning Efforts Austin Urban Trails Plan (2014): This plan identifies an opportunity for a trail along the Williamson Creek for three miles from Onion Creek to South Menchaca Road. It rates this trail as a Tier II priority, due to its proximity to major employers, public and private schools, access to transit, access to public places, and potential for completing gaps in existing on-street sidewalks or bike facilities.

Hydrology Williamson Creek Watershed Beyond the Greenway Vision Plan area, Williamson Creek stretches almost 19 miles across South Austin from its headwaters just west of the intersection of Highway 71 and Covered Bridge Drive to where it empties into Onion Creek just east of 1-35 at McKinney Falls State Park. This water then flows from Onion Creek into the Colorado River, where it travels across east Texas and empties into the Matagorda Bay and the Gulf of Mexico. The Williamson Creek Watershed, which contains Williamson Creek and its tributaries, covers 30.25 square miles. Thirty percent of the Watershed’s land falls within the Edwards Aquifer Recharge Zone, land that is regulated by development code to ensure the continued function and quality of the Edwards Aquifer, a critical underground water source for central Texas. The Central Williamson Creek area drains 72.5% of the Williamson Creek Watershed (about 22 square miles). About 34% of the Williamson Creek Watershed is covered by impervious surfaces. Land use within the watershed is comprised by 41% single family homes, 9% apartments and condos, and 9% greenbelts. Tree canopy covers 38% of the watershed, and this high number is likely due to high residential land use and greenbelts within the watershed. A high percentage of trees surrounding the greenbelt may help alleviate some flooding. Between rainfalls, Williamson Creek almost completely dries out, leaving occasional standing pools of water. 112 Photo: Austin Parks Foundation Many seeps and springs arise from the rocky outcropping that runs along both banks of Williamson Creek. 113 Central Williamson Creek Greenway Vision Plan MARCH 2021DRAFTCentral Williamson Greenway Creek Vision Plan MARCH 2021 DRAFTFlooding Austin averages about 34 inches of rainfall per year, with May, June, and October being the wettest months of the year. Rainfall tends to come in intense, short storm events that cause flash floods. Severe rain events can cause dramatic changes in the volume of water flowing through Central Williamson Creek, transforming the space from what is mostly a dry, rocky creekbed into a rapid stream of water. While flooding is an important part of the creek system and provides water flows for plant and animal species, these extreme rainfall patterns pose a threat to those living along Williamson Creek.

Major floods in 1998, 2001, 2013, and 2015 prompted a buyout program that has seen 51 properties purchased by the City, demolished, and converted into open space owned by the Watershed Protection Department. This Williamson Creek Flood Risk Reduction program helps to mitigate the risk of damage to property by removing houses that have experienced repeated flooding out of the floodplain and maintaining these areas as floodable open spaces. Water Quality The 2017 Watershed Protection Department Integrity Index report found that the Watershed has a very good overall condition for aquatic life, water quality, contact and non-contact recreation, and habitat and sediment quality. However, there are many stormwater outfalls that empty into Williamson Creek, bringing stormwater runoff with pollutants from roads, parking lots, and other impervious surfaces into Williamson Creek. These common pollutants may include pesticides, fertilizers, construction debris, used car oil, and trash. Critical Environmental Features The City of Austin defines Critical Environmental Features as natural features that protect and enhance water quality. As of June 2020, The Williamson Creek Watershed has twenty-nine known springs and seeps, fifteen rimrock/bluff locations, and 55 wetland sites. These three images of rimrock, a seep, and a wetland were all found along Central Williamson Creek. Rimrock Seep Wetland Rimrock and bluffs are outcroppings of rock that exceed a 60% slope, have a 5 foot rise, and a 40 foot length. Springs and seeps are locations where ground water reaches the surface and begins to flow overland. Wetlands along Williamson Creek are identified by the type of vegetation found within them.

Some ideas can have different levels of effort, and therefore may appear in more than one tier. All ideas, once implemented, will have perpetual maintenance requirements following their completion. The “Tiers” are as follows: Tier 1: Community-and non-profit-led efforts that are relatively low-cost and easy to install without technical equipment, machinery, or skills. Tier 2: Projects led by a city department, most likely the Parks and Recreation Department or Watershed Protection Department, with community volunteer and engagement opportunities. Tier 3: Large-scale city-led projects that may be implemented in the long-term by city staff or contractors. Maintenance All projects, no matter the size, will require maintenance for ensured community and environmental health and safety. Similar to implementation, these have levels of engagement and operations. As City-owned public land, community-led efforts must be approved by the property owner. Community -led collaborations with City of Austin landowners Watershed Protection, and the Parks and Recreation Department. They can involve work and support with non-profits such as Austin Parks Foundation and Keep Austin Beautiful. All projects must have prior approval by City of Austin property owners. Toolkit Items Include: • Nature Trails • Creek and Woodland Restoration • Fitness Programming • Food Forest • Community Gardens • Mountain Bike Trails • Labyrinth • Music Grove • Seating • Pollinator Nesting Boxes Maintenance Considerations: For Tier 1 community and city-partnered projects, a maintenance agreement must be developed and approved by the City of Austin. Tier 1 Projects Tier 2 Projects Tier 3 Projects These are City of Austin landowner projects of $50,000 dollars or less. They are part of the missions and plans of WPD or PARD, but require advocacy from the community. The community may also be involved for portions of these projects such as planting days. Toolkit Items Include: • Nature Play • Green Infrastructure • Wildflower Meadows • Community Message Board • Bonded Wood Mulch Trail • BYO Hammock Grove Tier 2 projects should be maintained per City code and operations; however, the City may partner with non-profits and community groups to perform maintenance. Projects that require long-term study and funding by City of Austin landowners that will total more than $50,000 dollars and require major construction. Funds and grants may be raised on behalf of the community to implement these projects.. They will have required community engagement on their further development and route to implementation. Toolkit Items Include: • Land Acquisition and Easements • On-street Bicycle Lanes • Sidewalk-Shared Use Path • Green Infrastructure (Large Scale) Maintenance Considerations: Tier 2 projects should be maintained per City code and operations; however, the City may partner with non-profits and community groups to perform maintenance. • Invasive Species Removal Maintenance Considerations: 120 121 Central Williamson Creek Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Vision Plan MARCH 2021 DRAFTT AREA 1 TIER 1 - 15,000-30,000* TIER 2 - 206,000 TIER 3 - 320,000 IMPLEMENTATION STREAM OPINION OF PROBABLE COST BY AREA AREA 3 TIER 1 - 15,000-42,000* TIER 2 - 150,000 TIER 3 - 740,000 Meadow Creek Trailhead T T Orland Trailhead AREA 2 TIER 1 - 15,000-30,000* TIER 2 - 175,000 TIER 3 - 340,000 A T T Heartwood Community Garden Emerald Wood Community Garden T 122 123 Central Williamson Creek Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Vision Plan MARCH 2021 DRAFTand sidewalk networks. This would further support an Urban Trail if it moves forward at a later date. The ‘High Water Route’ could also serve as a framework for a streetside urban trail in the Central Williamson Creek Greenway area. The next phase for a Tier I trail would be for the City of Austin to commission a Preliminary Engineering Report from a team of consultant licensed engineers and landscape architects. This phase also requires community engagement. The Visioin Plan recommends that the Central Williamson Creek Greenway community leaders and working group to be included as stakeholders in this process. September 2014 City of Austin Urban Trails Master Plan Ongoing City of Austin Projects There are several projects in an array of planning and implementation stages adjacent to the Central Williamson Creek Greenway. Flood Plain Buyout Cleanups The Watershed Protection Department has several projects underway to clean-up floodplain buyout lots. Such improvements include using split-rail fences to denote property boundaries, and removal of driveway concrete and debris. Buyouts are likely to continue, so additional land may be acquired and require community iput on their mantenance and public use. 2014 Urban Trails Master Plan The 2014 Urban Trails Master Plan identified Williamson Creek as a location for a Tier II trail. The proposed trail is a 12-foot wide concrete trail. The Urban Trails Master Plan is currently being updated and looking to assess which Tier II trails should be moved to Tier I. During the community engagement process for Central Williamson Creek Greenway, community members expressed a strong desire for trails within the greenway to be natural trails. This was stated in community meetings and shown in the Creek Ideas Card voting. As such, the Central Williamson Creek Greenway Vision Plan shows primarily nature trails and mountain bike trails with small accessible loops at trailheads. For street biking and connectivity, the Vision Plan proposes a ‘High Water Route’-- a series of bike lanes and shared- use paths out of the floodplain that would connect to existing and planned bicycle Middle Williamson Creek Flood Risk Reduction - Engineering Feasibility Study Phase 2 The study reviews methods to reduce flood risk over an area of Williamson Creek between West Gate Blvd and Congress Avenue. Some options requiring construction include: flood walls, which would consist of wall segments protecting specific areas from flooding; channel modifications, which would require excavation at some locations along the creek in order to increase the flow capacity; construction of detention ponds; or a diversion, which would allow water spilling out of the creek to be diverted through underground pipes in order to bypass areas at risk of flooding. The above options are being considered individually or as a combination. Another option considered is voluntary buyouts of homes at risk of flooding. Each of the options is being evaluated for flood reduction effectiveness, cost, as well as environmental impacts. Social impacts will also be evaluated once community engagement is conducted, after the draft feasibility report is available. This community engagement is expected to take place in February or March 2021. More collaboration with the community is needed so that the creek environment should be improved, conserved and remain natural in appearance. 124 125 Central Williamson Creek Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Vision Plan MARCH 2021 DRAFTSignage Labyrinth Informal trail markers such as cairns may be implemented to mark distances and direction along trail. A labyrnith may be a community -led project with City approval on all aspects of the design. Labyrinths may be constructed of rock berms from native stone quarried within a 100-mile radius of the site. Configuration of a labyrinth should allow water to drain. Stone berms should not be greater than 18-inches in height. Signage in this tier includes weather warnings, community message boards, educational information, interpretive signs, and trail distance markers. These signs can be up to 6ft in height and must follow the materials guidelines outline in Appendix X. This scale of signage will include monument signs and park rules. These signs require a third-party professional fabrication and are often included as a component of a larger project. While a labyrinth could be designed and constructed as part of a larger project, the Vision Plan recommends community input and engagement. The abyrinth was conceived of as a mindful way to bring community members together. Implementation By Idea Pollinator Nesting Boxes Invasive Species Management Many plans for these boxes can be found online. Nest boxes consist of a house with a roof and an infill of material such as bamboo and twigs. The house, roof and post must be wood, sourced from a non-threatened tree species. For more information on materials, refer to the materials appendix. The infill may be constructed from materials found on the greenway- in particular from material salvaged from the invasive species removal efforts. http://www.xerces.org/sites/default/ files/2018-05/12-015_02_XercesSoc_Nests- for-Native-Bees-fact-sheet_web.pdf Invasive species removal at the Tier 1 level includes community volunteers leading a Watershed Protection or PARD approved clean-up day, that can also be supported by local non-profits such as Keep Austin Beautiful or the Austin Parks Foundation. Removal will be done by hand only and can include pulling herbaceous noxious weeds such as Johnson Grass, Bermuda Grass, using weed wrenches to remove mid-sized shrubs such as Nandina and tree girdling to remove Ligustrum spp. No herbicides or motorized mechanical equipment may be used as part of this effort. Projects at the Tier 2 level are led by the Watershed Protection Department (WPD) or the Parks and Recreation Department (PARD) but can include community volunteers as well as non-proift organizations that contract with WPD or PARD such as The Other Ones Foundation and Texas Conservation Corps. Projects can also include machine removal of invasive trees. Projects in this Tier will be a component of a large -scale project that is greater than $50,000 in value. Projects will be responsible for removing any invasive material within their limit of construction.

Old infill may be scattered away from the nest box to decompose. Also, box keepers should watch for any infestations and spider webs to ensure bees are safe from predators. Invasive Species removal sites require continued maintenance. Often the soil has a continued seed bank of invasive species that will emerge following the removal of established plants. Quarterly inspections and seedling removals are recommended to ensure that sites are not recolonized. Addionatlly, native seeds and plugs should be installed at removal areas. Signs should be made of durable material that will withstand exposure to elements such as cut metal and stone. Detailed educational signage with images should be placed in the shade to reduce fading over time. Maintenance should be performed on signs once a year to remove dirt and graffiti. Typical maintenance will include a yearly inspection of the Labryinth. Tier 1 Labyrinths will require weed removal and should also be inspected after a flood event. Any shifted material should be restored to its original condition. 127 Central Williamson Creek Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Vision Plan MARCH 2021 DRAFTNature Trail Wildflower Planting Music Grove Nature Trails may be installed with City of Austin approval by community members or community members in partnership with non-profits such Keep Austin Beautiful and Austin Parks Foundation. Nature Trails should consist of a 6-foot-wide pathway. The pathway material should be single grind hardwood mulch that does not contain invasive seeds. Projects in the Tier 2 category could be a typical nature trail, but with City of Austin supported installation. Also, Tier 2 includes projects where technical review and skills are required to install nature trails, such as traversing steep slopes. In these cases, City of Austin property owners may work within their department or contract with local trail building non-profits such as the Texas Conservation Corps. Due to the technical nature of the planting process and equipment required, all wildflower meadow seedings should be implemented by City of Austin property owner. Tier 1 music grove can involve informal seating areas distanced from private property. Natural elements may be used for seating material such as stumps and boulders between 18-24-inches in height. Wildflower meadows can be established by City of Austin property owners. Establishing a meadow can be a multiyear process. Community members can advocate for meadows. Tier 2 improvements could enhance music grove areas by providing an accessible route in permeable paving and accessible seating. Implementation By Idea, Cont. Creek + Woodland Restoration At the Tier 1 level, community members and non-profits may partner with City approval to plant native trees, perennials and grasses to improve the environment. A list of acceptable species is provided in Appendix X Plant Species. Tier 2 restorations may involve small- scale site grading, planting and temporary irrigation. These projects will be conducted in part by the City of Austin and may also involve non-profits and community volunteers for some aspects of the work. Tier 3 projects involve large-scale improvements to the environment and creek. The projects may include repairing eroded banks, hydrologic engineering and changes to the creek, soil analysis and improvement and ecological restoration of wetlands and riparian areas.

Supplemental water until plants are established are recommended where feasible. Trails should be maintained per City of Austin standards. Community groups can assist in maintaining trails through cleanup days and replenishing the mulch. After storm events trails should be checked for debris and washout. Wildflower meadows must be maintained according to City of Austin requirements to ensure they are functioning correctly. Music groves should be maintained biannually to be kept clean and clear. 129 Central Williamson Creek Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Vision Plan MARCH 2021 DRAFTImplementation By Idea, Cont. Community Message Boards Green Infrastructure A E D I 1 R E I T 2 R E I T 3 R E I T Community Message Boards should be constructed of a non-threatened North American hardwood or suitable reclaimed lumber.

Excellent way to share about upcoming community events and organizations. E Recommended that neighborhood C N A N E T N A M I Recommended that community members who own property consider cisterns or rain gardens with native plants to treat and slow the water entering the greenway. All green infrastructure projects on City of Austin property should have a review by a civil engineer to ensure they are sized correctly. Small-scale green infrastructure such as raingardens, vegetated swales, rock berms and curb cuts are recommended to allow for run off absorption and treatment prior to entering Williamson Creek. Look for opportunities whenever a projects is mobilized, such as a driveway removal at a floodplain buyout or demolition of existing structure. Add excavation work into these plans and keep access to water for establishment of planting. The greenway has an opportunity for large scale green infrastructure projects. These projects include diverting stormwater outlets into biofiltration or wetland areas along the creek, and creating larger basins at manholes coinciding with flood plain buyouts. These interventions will require designs by licensed civil engineers and landscape architects and should also function as community and environmental amenities with opportunities for recreation and incorporation of native plants. Green infrastructure elements must be maintained according to City policy listed under the Environmental Criteria Manual. Community Gardens and Food Forests Examples of Food Forest at Tier 1 include expanding existing community gardens wtih Fruit Trees and Food Forest areas. Food forests can also be established, similar to community gardens, by working with City of Austin property owners. Nature Play For safety reasons all play elements must be Tier 2 or higher. At the Tier 2 level, City of Austin property owners could work with non-profits and land managers to establish a series of Food Forests within the Greenway. Community engagement would be recommended to optimize longterm maintenance and care. Tier 2 features include imaginative play elements that do not require safety fall surfacing. Elements may include tree step stones, vine tunnels, and child-sized raised garden beds. These require design, review and approval by City landowners. Food forests are a recommended part of large-scale improvements. Maintenance groups must be established for successful implementation. Tier 3 Nature Play elements include a combination of active and imaginative play elements. Any play element requiring a safety surface will fall in this category. Such elements include balance beams, swings, and climbable elements. Community engagement will be required for these designs. Maintenance can vary depending on size of Food Forest. At a minimum, plan for watering plants through establishment, quarterly weeding and developing a harvest schedule. Maintenance varies depending on the play type. All play elements should be maintained by City of Austin.

Bonded Mulch Trail A Land Acquisition Fitness Programming On-Street Bike Lanes At the Tier 1 scale community members could advocate with the City and land owners to establish easements for parkland or acquire additional buyout properties along the greenway. In particular, community groups partnering with private land owners could establish a series of easements that would allow for more continuous trail and park areas through the greenway. Bonded wood mulch trails will be fully accessible routes that require grading and design by professional engineer and landscape architect to implement. Installation must be performed by a third-party contractor. Tier 3 includes land aquisition by the City, such as additional floodplain buyouts. It also includes dedication of park and trail easements for developments adjacent to the greenway. Bonded mulch trails should be cleaned yearly by spraying a clear coat material to keep the surface well -bound and prevent wear from eroding the surface layer.

Paid activities require permission from the City of Austin Projects at this level can include maintaining a mowed area for activity use, small grading projects, elements, such as metal bars for pull ups or limestone block or boulders to use as aids in kinesthetic and body weight exercises. This would include commercial-grade activity equipment, such as a hand-cycle or recumbent bike. Equipment of this type must include an accessible route and safety surfacing. Equipment should be located at trailheads out of the floodplain only. Additional community engagement is required for this type of equipment. Smaller elements noted in Tier 2 could also be incorporated into Tier 3 projects. Nature Trails may be installed with City of Austin approval by community members or community members in partnership with non-profits such Keep Austin Beautiful and Austin Parks Foundation. Nature Trails should consist of a 6-foot-wide pathway. The pathway material should be single grind hardwood mulch that does not contain invasive seeds. Projects in the Tier 2 category could be a typical nature trail, but with City of Austin supported installation. Also, Tier 2 includes projects where technical review and skills are required to install nature trails, such as traversing steep slopes. In these cases, City of Austin property owners may work within their department or contract with local trail building non-profits such as the Texas Conservation Corps. On-street bike lanes require design and review by Austin Transportation Department. Community members can advocate for bike lanes by contacting the ATD. On street bike lanes should be maintained by City of Austin per City standards. 133 Central Williamson Creek Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Vision Plan MARCH 2021 DRAFTPeople Experiencing Homelessness Austin’s parks and open spaces are places where all community members gather to enjoy trails, build social capital, and access Austin’s urban nature. Due to the diversity of groups and interests of Austin residents, it is not surprising that conflict may arise between park users. Conflicts between neighborhoods, park users, and unsheltered individuals living in Austin’s parks has become an ongoing issue in Austin, and Williamson Creek is no exception. In the past decade, the City of Austin has seen a significant uptick in unsheltered individuals residing in Austin’s Parks. This is due to a variety of factors, including Austin’s ongoing affordable housing shortage crisis and population growth. In 2019, Austin City Council enacted a set of ordinances that permitted people experiencing homelessness to sit, sleep, lie, and camp in most public spaces. The homelessness crisis was further exacerbated by 2020’s COVID-19 crisis, when the number of unsheltered individuals rose 45% from 2019 to 20201. Across the city, residents and park users have voiced concerns over the symptomatic impacts of Austin’s housing and homelessness crisis, such as the presence of unsheltered individuals in parks, and their associated tents, belongings, and refuse. There have been many calls to remove encampments in parks and open space. However, this is a short-term response that may only hinder efforts by support services and unsheltered individuals seeking long-term housing solutions. Park clean-ups also strain city department resources, draining time and money away from parks improvements city-wide. The displacement of people experiencing homelessness from parks in this manner 1 https://www.austinecho.org/about-echo/ homelessness-in-austin/ 134 also further entrenches homelessness. After a clean-up, displaced individuals may simply relocate to a new area on public land, making it difficult for organizations that provide support services to locate them to connect them to housing and other resources. When clean-ups dispose of people’s belongings, this further burdens unsheltered individuals. They must then use their limited financial means to purchase or procure more blankets, tents, or supplies needed to survive living outdoors and limits their ability to spend money on food, transportation, and shelter. Fully addressing the causes of homelessness is a complex and long-term undertaking that is outside the scope of this Vision Plan. In the short-term, taking an empathetic and communicative approach may help ameliorate conflicts. At Central Williamson Creek Greenway, the following approaches are recommended: 1. Prioritize project implementation in areas along Williamson Creek that will not displace people experiencing homelessness, work with the city to implement projects with participation of unsheltered individuals. 2. Post the names and contact information of resources like The Other Ones Foundation (TOOF) to community message boards. Many unsheltered individuals are not aware of community resources available to help them secure shelter, personal hygiene, food, access to the internet, and other necessities. 3. Temporarily employ unsheltered individuals on land improvement projects. The City of Austin contracts with The Other Ones Foundation (TOOF) on projects like trail-building and invasive species removal. Consider coordinating between the COA and TOOF on appropriate projects along the greenway, including: • Creation of Nature Trails • Creek and Woodland Restoration • Community Gardens • Invasive Species Removal • Pollinator Nesting Boxes • Signage Installation Invest in neighborhood public education around unsheltered individuals, emphasizing the following ideas: • Those experiencing homelessness are part of our community. • It is possible for anyone to experience homelessness. • Everone is welcome to use public parks and open spaces • Those experiencing homelessness may face life-long issues, such as poverty, mental health concerns, physical ailments, and/or addiction. • Public complaints may strain park resources. • Public complaints that result in displacement may hinder long-term efforts to find housing for unsheltered individuals. homelessness. 4. Educate the neighborhood about the newly expanded Integral Care-EMCOT (Expanded Mobile Crisis Outreach Team) a branch of 911 that responds to all mental health-related 911 calls that do not present an imminent threat to public safety without the involvement of city or county police. Neighbors can be directed to request a mental health professional to resolve conflicts rather than police in an effort to stem the potential for police violence against an unsheltered individual and to better address non-violent crisis with the correct training. 5. Support affordable housing in the community. Connect with organizations like HousingWorks Austin, Austin Housing Coalition, and Reform Austin. 6. Advocate for trash cans and trash removal services to service these communities. Support shelterless individuals in taking a land stewardship approach to the spaces they inhabit by providing the resources to remove trash and refuse from the site as well as through educational programs on local ecology and general stewardship principles.

These goals, along with their corresponding design strategies, were created from both community input and trail, parks, and ecological design best practices. Upon approval from the City of Austin’s Parks and Recreation Board, this plan is to become a planning document of record, reflecting the desires of the Community Working Group, and the general public to create an ecologically sound and inclusive vision for the future of Central Wililamson Creek Greenway. With strategic investment and further design, Central Williamson Creek Greenway has the potential to become a major asset to the growing neighborhood and Austin Community. 138 139 Central Williamson Creek Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Vision Plan MARCH 2021 DRAFTBibliography Capital Area Metropolitan Planning Organization. “CAMPO 2045 Plan,” 2020 City of Austin. “City of Austin Urban Trails Master Plan,” 2014.

Appendix B Recommended Materials Criteria Selecting sustainable and safe materials for construction along Williamson Creek will ensure the continued health of the creek and lessen the environmental impacts of construction and development. Learn more about these strategies through the Sustainable Sites Initiative (sustainablesites.org). Many commonly-used landscape wood products are sourced from thretened tree species or threatened ecosystems. Minimize impact on these species by purchasing sustainably-sourced wood from non-threatened tree species. Salvaging landscape materials from on-site or from re-use suppliers like a member of the Building Materials Reuse Assocation is an effective way to divert waste from landfills and conserve financial resources. Salvaged plant materials also conserves native, local plant genetic pools. Review the Convention on International Trade in Endangered Species (CITES) website to review the status of tree species and ensure that is not threatened with extinction or listed as requiring trade controls to avoid utilization incompatible with their survival. www.cites.org/eng/resources/ species.html Identify salvaged materials suppliers or local demolition and construction projects. Search diirectories of reuse stores here: Building Materials Reuse Association, www.buildingreuse. org Habitat for Humanity’s ReStore, www.habitat.org/env/restores.aspx Use of new materials with a high recycled content reduces resource extraction and diverts materials away from landfills and into the production of new materials. Speak with local materials suppliers about products that may help achieve this goal. Examples of some materials include plastic lumber with recycled content, asphalt with recycled asphalt aggregate, and high recycled content steel. Use sustainable wood sources Use salvaged materials and plants Use materials with a high recycled content Review the Internationan Union for Conservation of Nature’s “Red List of Endangered Species to ensure the species is not in danger of extinction. www.iucnredlist.org. Get in touch with a local native plant conservation group. Many of these groups “rescue” native plants from construction sites, and may be able to provide locally- sourced salvaged plants. Learn more about recycled products and industry materials recycling. The U.S. EPA Industrial Materials website: www.epa.gov/ industrialmaterials The U.S. EPA’s Comprehensive Procurement Guidelines www.epa.gov/cpg Green Building Research Guide’s searchable database, www.greenguide.com/ exchange/search.html Reuse Development Organization, www.redo. org California Department of Resources and Recycling, Recycled Content Products Directory, www.calrecycle. ca.gov/RCP/default.asp 144 145 Central Williamson Creek Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Vision Plan MARCH 2021 DRAFTRecommendation Intent Strategy 1 Strategy 2 Strategy 3 More Resources Soils, compost, mulch , boulders, and aggregate sourcing should occur within 50 miles of the project site. Plant material should be grown and supplied within 250 miles of the site. The extraction, harvest or recovery, and manufacture of all other materials should occur within 500 miles of the site. Specify products from manufacturers who can provide chemical inventories covering all chemicals in each life cycle stage of the product. Manufacturers should also report all known hazards and their concentrations. Use materials without topical finishes or other chemical additives whenever possible. Learn more about chemicals in building products by consulting Pharos Project’s Chemical and Material Library at www. pharosproject.net/material. United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS), www.osha.gov/dsg/ hazcom/ghs.html. Sourcing regional landscape materials and plants has many benefits, including reducing the use of fossil fuels used for transportation, supporting local economies, increasing the demand and therefore the future supply of native plants, and supporting regional identity through the use of local materials. Use materials that do not contain chemicals known to harm human health or aquatic health. Prioritize materials that have chemical inventories, life-cycle information and hazard assessments. In addition to eliminating harmful chemical runoff, do not use materials that contribute sediment or aggregate to the creek. Use regional materials Use materials that will not harm the health of Williamson Creek or human health.

The prompts provided helped individuals think through the future of the Greenway or host meaningful conversations with family and friends. a community-led vision for a resilient and connected urban floodplain Greenway COMMUNITY CONVERSATION TOOLKIT WHY ARE WE DOING THIS? Floodplains in Texas cities are expanding as storms become more intense and more frequent with climate change. As a result, urban communities increasingly face the dual challenge of protecting human lives and sustainably managing flood-prone urban landscapes. Williamson Creek in South Austin has been continually ravaged by floods over the last two decades. As a result, the City of Austin and U.S. Army Corps of Engineers partnered on a buyout process beginning in 2015. With 17.8 acres of flood buyout properties, combined with 58.3 acres of underutilized park-land, the central portion of Williamson Creek represents an opportunity to re-imagine this floodplain as a resilient collective and connected space in partnership with an ethnically and socioeconomically diverse community.

I come into the peace of wild things who do not tax their lives with forethought of grief. I come into the presence of still water. And I feel above me the day-blind stars waiting with their light. For a time I rest in the grace of the world, and am free. by Wendell Berry centralwilliamsoncreek.org 268 269 Central Williamson Creek Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Vision Plan MARCH 2021 DRAFT270 271 Central Williamson Creek Vision Plan MARCH 2021 DRAFTCentral Williamson Creek Vision Plan MARCH 2021 DRAFT
