estled along Georgia’s hundred miles of golden coastline, the City of Hinesville serves as the growing seat of Liberty County and home of Fort Stewart, the largest US Army installation east of the Mississippi River. With explosive growth from the 1950s onward, Hinesville faces a number of issues stemming from rapid growth, including the treatment of stormwater runoff. Following decades of sprawling growth, residents and leaders now seek to rediscover and reinvest in the community’s historic downtown. With continued growth on the way, Hinesville officials sought the assistance of the University of Georgia’s Carl Vinson Institute of Government to help create a plan that would bring energy and life to the downtown area. The result of this collaboration, the Hinesville Renaissance Strategic Vision and Plan (RSVP), incorporates the voices of community members, civic leaders, business owners, and major downtown stakeholders to create a cohesive, community-supported concept for the future. Supported by partners including the Georgia Municipal Association and the Georgia Cities Foundation, this document creates a roadmap for a more vibrant and community-focused downtown. Although many issues were identified during the RSVP process, nearly all citizens agreed on a single top priority: creating a vibrant downtown with a diverse array of dining, family-friendly activities, and entertainment options. As part of this vision, many community members wanted Hinesville’s central Bradwell Park transformed from an overlooked and underperforming square into a centerpiece for the community. With concepts developed from plans included the Hinesville RSVP, in September N ONTE TS of 2019, students from the University of Georgia C College of Environment and Design develOF oped 16 unique visions for this important LE public space.

tudents from UGA’s College of Environment & Design’s Sustainability Studio were invited to prepare plans for downtown Hinesville’s Bradwell Park. Students spent time at the coast as part of the studio and their ecology class. This field study allowed students to examine coastal context and ecology to inform their design. The design effort commenced with Ro Krueger from the Hinesville Downtown Development Authority providing background about the community. This furthered information Danny Bivins presented as part of the Hinesville Renaissance Strategic Vision and Plan (RSVP) that set up opportunities for park redesign. John Baker kindly led students on a downtown walking tour where he shared opportu¬nities and constraints that informed park redesign. Students were also tasked with creatively managing stormwater to support an effort led by Scott Pippin. As part of this effort, students worked to improve the quality of runoff from urban areas that drain to Peacock Creek as part of a federally funded water improvement project. The first step of park redesign included creating an inventory of existing conditions. Students measured, sketched, and photographed park elements and chatted with a few stakeholders while enjoying lunch at restaurants adjacent to the park. Next, students created a program that solidified existing and proposed uses within the park. With a program in hand, students could analyzed the site to prioritize or exclude program¬matic elements to inform design. Individual student-led designs celebrated the uniqueness of downtown Hinesville with by preserving some of the functions such as: • Tactical public art
• Adding canopy shading
• Large and small gathering spaces
• Treating and routing the first 1.8 inches of rainwater that falls onto the park site in ecorevelatory ways to promote green infrastructure
• Retaining existing vegetation • Adding indigenous plants • Seamlessly tying into the vehicular and porous pedestrian circulation systems
Many of the plans on the following pages skillfully incorporate these program¬matic elements in ways that reinforce alignment among design elements. Jurors remarked that each plan produced an element that, when combined, gives rise to a park design that celebrates public art and provides a variety of usable and functional spaces. Together these elements might inspire adjacent landowners to fully embrace their relationship with the park. In addition to improving the social elements, such as retaining a simi¬lar gazebo space, the designs supported ecological objectives that use indigenous plants to promote pollinators and help treat, cool, and slow stormwater runoff. As you page through the following designs, you can see that students played a criti¬cal part informing park design evocative of the coastal area that will be enjoyed by many who will have the chance to use the park in their own way. 4
Students made a site visit to Bradwell Park that informed their final designs.

inesville, Georgia is a community with a rich history. In order to ensure its longevity, the city reached out to UGA to assist in planning for social, economic, and environmental sustainability. The goal of this project, through a 319 Grant created by the Clean
Water Act, was to work in conjunction with the existing downtown development concept to reduce stormwater runoff into the polluted Peacock Creek. This shows my design concept for Bradwell Park - the heart of the downtown. It works to implement green infrastructure to achieve the goals of the grant as well as activate downtown through the addition of streetscape plantings, public spaces adjacent to existing attractions, and flexible event spaces that work with existing parking and circulation. In addition to the park concept, the diagram below shows where these streetscape treatments can be repeated throughout downtown as funding becomes available. By first revitalizing the core of the downtown and then expanding upon this design, it is my hope that Hinesville will be socially and environmentally prepared to continue thriving long into the future.

radwell Park in the city of Hinesville, Georgia anchors the city’s historic downtown. A reinvestment in Bradwell Park activates downtown’s central core and creates both a landmark and a destination for Hinesville. This design strives to strike a balance between economic, social, and environmental benefits. Economical, the proposed Live Oak fountain creates a motive for people to spend time downtown, where they are then more likely to shop and dine. Socially, the design provides multiple spaces for varying social interaction. Movable seating allows freedom of movement and gathering spaces such as the gazebo and fountain encourage community interaction. Environmentally, the park is designed to treat storm water runoff from both the park and its adjacent roadways. The four large rain gardens infiltrate 100% of their watersheds, the pathways consist of permeable pavers that allow for infiltration, and all vegetation is composed of native plantings that provide greater ecological benefits.

his project is a segment of a bigger project to renovate the downtown area of Hinesville, Georgia. Bradwell Park is located at the center of the downtown area and serves as a community public event space for the city. My redesign for Bradwell Park is focused on bringing high quality scenic values to the downtown and stormwater runoff treatment. The vegetation edges are inspired by the coastal deltas of Georgia, this is only befitting as Hinesville is situated in close proximity to the coast. The night time lights are provided to bring color to the city downtown at night, which adds illuminating aesthetics. I designed 9% of the park as rain gardens to treat storm water runoff. Plant selections were based on fall color, summer and spring blooms, and winter shed to bring a different aesthetic look to the park all year round. I introduced a playground to encourage kids to make use of the park too.

radwell Park is the central space for meetings of culture and arts in Hinesville. This design considers not only how the space has been used in the past, but also the potential for how the space could be used in the future. As a multi-purpose site, this design features open and curvilinear “rooms” with copious shade for pedestrians and raingardens for stormwater management. The “rooms” in the park are large enough to hold multiple tents for the farmer’s market and other events. While Hinesville is in the coastal region of Georgia, it is not directly on the coast. In order to bring the culture of the coast to the site, this alternative features plants unique and signature to the coast of Georgia. The live oak that anchors the space is preserved in this design alternative not only for ecological reasons, but also to create a more coastal aesthetic on the site. The water sculpture fountain and renovated gazebo not only fit within the architecture and coastal milliea of downtown, but also bring a modern and fresh design facet to the site.

his project aims to redesign Bradwell Park to create a more enjoyable and sustainable place for the residents in Hinesville, Georgia. Proximity to the Georgia coast provides the inspiration for this design with aesthetics but also in planting choice and the important consideration for rising sea levels that will one day affect the city of Hinesville. An integral piece of this design includes the use of Reciprocating Wetland technology to mimic daily tides to filtrate storm water. Reciprocating Wetlands technology, patented by the Tennessee Valley Authority, mimics and accelerates natural tidal processes to quickly and efficiently treat wastewater. The RecCip system uses a fill-anddrain process based on daily tidal cycles, where each cell contains specialized aggregates and hydroponic plants creating an ideal habitat for treatment biofilms. The systems are not only attractive but also odor free, low-maintenance, and have a compact footprint. They are designed to treat 300,000 gallons per day. In this project, there are five proposed RecCip planters that will be planted with Spartina and Black Needle Rush with the goal of treating storm water and bring the coast to Hinesville. Ultimately, the goal of this project is to prepare the city for climate change and reconnect Hinesville to its coastal heritage.

radwell Park is the only public park that lies in the central core of downtown Hinesville. The main objective of the Bradwell Park Redevelopment Project is to create a space for people, considering all the factors such as social, economical and environmental, and to motivate people to stay longer in the downtown area. The proposed design of Bradwell Park is focused on providing social green spaces for citizens with rectangular symmetrical designs that compliment the classical architecture of the historic downtown. The central sunken plaza around the existing live oak provide enough seating space for people, which facilitates either resting or interaction. Along with that, shaded pergolas and the redesigned gazebo provide additional seating spaces. A long circulating water pool and interactive water feature mitigates heat in the park area. Introduction of wetland plants in the water pool and in the raingarden helps provide information to the people about native plants in the coastal area and their importance. The elevated deck area and open space in the park provide space for various occasions such as additional booth space for the farmer’s market, art exhibitions, night events, or live music. Additionally, the use of permeable surfaces and raingarden helps with stormwater management.

Bradwell Park Revitalization RUOLIN GU
Located in the center of downtown Hinesville, Bradwell Park is an ideal recreational destination. The idea of the design is to revitalize the downtown area and create an environment-friendly park that manages the runoff in the adjacent area. The topography of the Bradwell Park redesign is terraced from the highest plaza to the lowest stormwater wetland. It ensures the park could collect runoff in the adjacent area as much as possible. There are two shallow rusty metal water channels on the ground of the gravel plaza. On a rainy day, the channels could efficiently drain the rainwater from the gravel ground to the rain gardens. The two triangle shape rain gardens could collect runoff from both the plaza and the adjacent area. Since the west side of the site is close to local restaurants, outdoor seating is placed on the edge of the rain garden. On the east side of the park, terraced lawns, stairs and a splash pad make it a decent location for citizens to gather. During the farmer's market, the stairs and lawns provide a place for people to relax. The water feature in the south of the park is separated into two parts. The section with the splash pad aims to encourage people to interact with the water and revitalize the park. Separated by a bridge, the other part is a stormwater wetland located in the lowest point of the park. Because of the terraced topography, the stormwater wetland would catch the rest of the runoff.

The City of Hinesville, Georgia is located near the coast, which determines specific coastal features. In order to provide a more amiable livelihood for both of the communities and the visitors, Hinesville seeks to rejuvenate the downtown area by leveraging Bradwell Park to attract residents and visitors. This design showcases a possibility that by introducing the rain gardens which initiated the native plant strategy, and the interactive water features, to contract the social factors and site properties. In lieu of occupying the limited land for gardens, this design attempts to create two layers in order to leave a space for human activities. The lower layer is built concave for water retention and growing plants. The upper layer is made with permeable materials that allow water to infiltrate. With the land area optimization strategy, this proposal seeks to create an artistic landmark, as well as a comfortable public space.

Bradwell Boardwalk E N J OY M E N T. EC O LO GY. E L E VAT E D DAV I D E VA N S
The Bradwell Boardwalk maximizes stormwater treatment and infiltration by elevating most of the social spaces above the ground plane. A classic coastal boardwalk puts patrons at ease by reminding them of Hinesville’s nearby seashore. A combination of open plazas and smaller, more intimate vantage points support a range of park uses from social gatherings to a restful lunch. Permeable turf pavers on the eastern edge of the Boardwalk provide green space and parking for the regular farmer’s market while larger spaces on the Boardwalk provide spaces for additional tables to be set up. Rain gardens on-site are capable of treating and infiltrating 1115 c.f. per day, or 156% of the required water quality volume. The Boardwalk’s watershed extends up to the corner of Midway and Main Street to the northwest by means of curb cuts and storm drains that convey runoff into the rain gardens.

Hill Park in Bradwell Park I N T E R ES T I N G C I T Y C O R E DINGNING YU
The redesign for Bradwell Park is called “Hill and Pond Park�and it contains micro-topographies to attract both children and animals such as butterflies and birds. The size of the site is about 70 feet wide and 220 feet long. Since 70 feet wide and 70 feet long is a comfortable size for people to see everything, the site is divided into 3 parts and each contains a rain garden to collect runoff. bench I hope that children can feel free to lie down on the hills and enjoy the sunshine. The hills are all around 2-5 feet high so children of all ages can find their own hill. There is a large oak tree on the site which is about 60 so hillfeet 2 feettall high the design protects this tree.

Bradwell Park Sustainability Plan T H E EC OTO P E E X P E R I E N C E B R I A N M E LC H I O N N I
The conceptual foundation for the Bradwell Park Sustainability design is grounded in the smallest ecological divisions of the Coastal Plain Ecoregion, also known as ecotopes. Representative plant communities from three ecotopes define the overall planting design, highlighting common species. The relationships between the ecotopes also display the need to educate the public on coastal resilience futures in which climate change may see shifting ecological and social communities along the Georgia coast. The educational component will be focused on signage that tangibly demonstrates how water moves through the landscape along the prominent park-long water feature, from headwaters to wetland.

The Boardwalk at Bradwell Park A H AV E N I N H I N ESV I L L E R OW J E R L E S
The Boardwalk at Bradwell aims to be a redesign that reinvigorates downtown Hinesville. Economically, a new and vibrant redesign can bring capital back into the area by providing a venue around which new commerce may develop. Prioritizing vine-covered shade structures and trees also create a comfortable space in which people will more willingly visit, socialize, or otherwise spend their time; especially in the long summer. Ecologically, this design hopes to do much for stormwater runoff capture and treatment. There are a total of six rain gardens designed to infiltrate as much water possible. Along the eastern curb, strategically placed grating will help water enter and exit the catchments. In total, there are over 4,000 square feet of rain gardens in this design.

Final Plan Design E M I LY W H I S E N A N T
A
reinvestment in Bradwell Park is crucial to the rejuvenation of downtown Hinesville. This design focuses on creating a year round destination and community space for the City of Hinesville. The first step in this design is to maximize the park’s parameters. The park extends 12’ north into Midway Street and 15’ east into Commerce Street, taking the place of existing parking. These changes coincide with the downtown Master Plan, emphasizing circulation and space usage in the downtown core. While this design concept emphasizes rejuvenation of the downtown community, it also produces numerous environmental benefits. With four separate rain gardens, totaling 2,519 square feet, and permeable brick pavers, over 90% of the water that falls on the park will be infiltrated on site. The rain gardens are designed along the edges of the park to also infiltrate and treat the stormwater runoff from the surrounding roadways. Infiltration and water treatment are important issues in urban areas due to their role in providing healthy water quality and preventing excess flooding. Canopy cover is another environmental factor that has been prioritized. Canopy trees provide needed shade for human activity, combat temperature control and heat island effects, purify air quality, reduce stormwater runoff and erosion, and produce carbon sequestration. In order to promote canopy cover, the design preserves the existing historic live oak and proposes three new oak trees.

PERSPECTIVE I The extension north into Midway Street makes room for a 1,300 square foot community stage. With simplicity in mind, the stage serves an array of events. From movie nights in the park to bands playing for a downtown festival, the open nature of the stage allows its use to be oriented toward the park or a closed-off street event. For shade, removable sun sails can be hung and taken down as needed. Adjacent to the stage is 6,500 square feet of open space. With over 4,000 square feet of paving and 2,000 square feet of lawn, the space can be utilized for large community festivals, the weekly farmers market, or simply a place to sit and enjoy lunch. Additionally, a 24’ opened edge along Commerce Street provides vehicular access to the courtyard. Seating is accommodated by movable cafÊ tables and chairs as well as 2 large concrete seat walls.

PERSPECTIVE II With the stage and open space anchoring the north end of Bradwell Park, the southern end is centered around a unique interactive fountain. One of the most prominent symbols of the southern coastal landscape is the live oak. An example of their majestic beauty can even be seen in the middle of Bradwell Park today. In reference to their prominence in Hinesville’s
42
landscape, the interactive fountain has been proposed as a sculptural representation of a live oak. Building a unique fountain creates a symbol for downtown Hinesville. It generates a destination for downtown, a starting point for the city to rejuvenate its vibrant downtown culture. In order to encourage play, the fountain is surrounded by a 1’ wading pool and the proposed seatwall and raingardens provide protection from surrounding roadways. Further, by proposing a sculptural fountain, Hinesville’s robust art community can be engaged in the fountain’s design process.
