The Hollygrove neighborhood was originally part of the McCarty Plantation, which was incorporated as the Town of Carrollton by the Louisiana Legislature in 1845. Construction of the New Orleans and Carrollton Railroad, which followed the current day streetcar line, increased settlement of Carrollton and in 1859 the town officially became a city.
From 1858 to 1871 a series of drainage improvements, including construction of Upperline Trail Race Canal (the current day Monticello Canal) and the Dublin St. drainage machine, laid the groundwork for later drainage infrastructure that ultimately permitted settlement of the Hollygrove neighborhood. In 1874 the City of Carrollton was annexed by the City of New Orleans. The citywide adoption of the 1895 Drainage Plan inaugurated the modern drainage system that is in use to this day. The area occupied by the present day Hollygrove neighborhood remained sparsely developed before the period of modern drainage. Rapid settlement of Hollygrove occurred in the 1920’s and 1930’s and by1965 the area had become a fully-occupied medium density residential community.
Hollygrove Timeline illustrates three major histories of the neighborhood’s development. Railroad, water infrastructure and neighborhood histories paint a telling picture of not only the community but also the development of the Greenline site over time.

“The first night I lived in my home in Hollygrove I was startled out of bed when the horn from the train blew.”
“We used to tell the time of day by the sounds of the trains. Twice a day, the engine, and the whistle, would let us know the time.”

“In the good old days my sisters and I used to play on the railroad embankment.”
“People used to wave at you in your backyard from the train, and we would wave back.”
“Anybody taking the train to New Orleans had to pass through this neighborhood.”
“Black folks from Hollygrove had to sit in the cars called ‘Smokin’ Marys,’ right behind the
locomotive coal engine.”

SITE STRATEGIES: Neighborhood Vision
Students of the Tulane School of Architecture conducted academic design analysis at the GreenLine site, creating a diverse series of designs that investigated the history of the site, the community’s desire for active, programmed open space, and introducing landscaping to help make the site a pleasant, occupiable public space to be enjoyed by Hollygrove residents and adjacent neighborhoods alike. 2

This proposal for the Hollygrove Greenline Park is based on the idea of water management education. Other goals of the design are to create a compelling outdoor space with flexibility as a central component, providing an emblem of neighborhood identity with a framework for adaptation by the local users. With a starting point of the unique mounded topography of the Greenline, the park is left almost completely without built structure, instead using formed earth to activate the site and direct the flow of storm water into a series of vegetated swales which provide a focal point of the park.
By dividing the site into three overlapping zones, space is allocated for each of the program requirements while maintaining flexibility in the usage. The southern zone consists of interconnected bioswale and elevated walkway emphasizing the educational component as users traverse the site. A ten-foot wide flat zone runs through the middle of the site which accommodates a wide range of activity while also allowing a passageway for potential vehicle usage. The third zone along the north edge of the site features a series of elevated spaces providing a framework for program activities, future expansion of community gardens, and a dynamic play space, while assisting in directing stormwater flow. By delineating specific “wet and “dry” zones, flexible open spaces are created and framed with water-responsive gardens.
In order to emphasize the idea of water management, the conceptual action of “peeling” the ground surface is used to enhance the relationship between the vegetated swale, boardwalk, and functional lawn space. As strips of surface material dip down into the swales, and up into elevated walkways above the swales, attention is drawn to the control of storm water and the vegetation which utilizes the runoff in rain gardens. This is further emphasized by the use of bright color on the undersides of the “peels” and on the thin strips of steel retaining walls. The built materials on the Greenline are minimal, and modular sections of boardwalk and thin metal retaining walls can be easily removed and stacked for convenient storage in case the site is used for Sewage and Water Board storage in the future.
In keeping with the idea of flexible usage for the Greenline strip, the education center, restrooms and storage are located on an adjacent site. This organization enhances the continuity of the Greenline and provides opportunity for different uses in the future. In this setting, the building also acts as an entry gate for the park, providing educational points of interest. By using a single, flexible structure for multiple program components, the flexibility of the site is maintained. The structure consists primarily of a classroom space which opens into a stage looking into the site. This composition allows for events of varying scales to be accommodated, as the audience can expand from small, indoor gatherings to a larger outdoor entertaining. The structure also serves as a shaded bus stop, adjacent to community information boards, a small lobby space for educational exhibits, restrooms and storage for maintenance and stackable furniture.

This proposal for the Hollygrove Greenline Park is based on the idea of water management education. Other goals of the design are to create a compelling outdoor space with flexibility as a central component, providing an emblem of neighborhood identity with a framework for adaptation by the local users. With a starting point of the unique mounded topography of the Greenline, the park is left almost completely without built structure, instead using formed earth to activate the site and direct the flow of storm water into a series of vegetated swales which provide a focal point of the park.
By dividing the site into three overlapping zones, space is allocated for each of the program requirements while maintaining flexibility in the usage. The southern zone consists of interconnected bioswale and elevated walkway emphasizing the educational component as users traverse the site. A ten-foot wide flat zone runs through the middle of the site which accommodates a wide range of activity while also allowing a passageway for potential vehicle usage. The third zone along the north edge of the site features a series of elevated spaces providing a framework for program activities, future expansion of community gardens, and a dynamic play space, while assisting in directing stormwater flow. By delineating specific “wet and “dry” zones, flexible open spaces are created and framed with water-responsive gardens.
In order to emphasize the idea of water management, the conceptual action of “peeling” the ground surface is used to enhance the relationship between the vegetated swale, boardwalk, and functional lawn space. As strips of surface material dip down into the swales, and up into elevated walkways above the swales, attention is drawn to the control of storm water and the vegetation which utilizes the runoff in rain gardens. This is further emphasized by the use of bright color on the undersides of the “peels” and on the thin strips of steel retaining walls. The built materials on the Greenline are minimal, and modular sections of boardwalk and thin metal retaining walls can be easily removed and stacked for convenient storage in case the site is used for Sewage and Water Board storage in the future.
In keeping with the idea of flexible usage for the Greenline strip, the education center, restrooms and storage are located on an adjacent site. This organization enhances the continuity of the Greenline and provides opportunity for different uses in the future. In this setting, the building also acts as an entry gate for the park, providing educational points of interest. By using a single, flexible structure for multiple program components, the flexibility of the site is maintained. The structure consists primarily of a classroom space which opens into a stage looking into the site. This composition allows for events of varying scales to be accommodated, as the audience can expand from small, indoor gatherings to a larger outdoor entertaining. The structure also serves as a shaded bus stop, adjacent to community information boards, a small lobby space for educational exhibits, restrooms and storage for maintenance and stackable furniture.

On arrival at the site, visitors are first introduced to the concept of a rain garden. Bioswales on either side of the site are used to move water to the rain gardens, which are planted with native plant species. Moving through the site, the visitor is able to pause at a pavilion within the tree farm, where they can learn about techniques of water collection and irrigation. In the farm, trees will be grown as saplings on the site, to later be transplanted strategically around the city to address a need for shade.

Next, a demonstration wall illustrates how landscape techniques can protect the home from water. At the edge of the central block is the deconstructed shotgun. The structure uses a lightweight foundation system that makes the classroom easy to remove in the event that the Sewage and Water Board needs to occupy the site. Wood framing is used to echo materials used in a typical New Orleans shotgun, and the back wall has been replaced with a perforated green wall that will provide shade in the summer and allow views into the bioswale below.

3Recent designs have brought the project closer to fruition, part of an ongoing partnership with the Tulane City Center and School of Architecture. Final designs are undergoing detailed cost analysis and will be presented to the neighborhood in October of 2013. Once approved, the CHCDC will continue in earnest to raise funds for implementation. Preliminary cost estimates are included here for reference.

The CHCDC strives to provide educational programming as part of the mission of developing the GreenLine site. This process has already begun in several ways, including the installation of demonstration rain gardens at five locations throughout the neighborhood. The CHCDC has engaged with the GreenLine owner, the Sewerage & Water Board, and hopes to maintain a close working relationship in order to meet the goals of providing educational programming regarding water management, urban agriculture, and other related topics.
The CDC is also working with Engineers Without Borders, who have provided surveying and water management strategies to inform the ongoing design process. Their focus on real, on-the-ground conditions and realistic water management strategies will allow the GreenLine site to serve as an example of sustainable de-velopment, further enhancing the CDC’s educational goals. 4

A rain garden is a planted depression designed to infiltrate stormwater runoff, but not hold it.
A rain garden is commonly known as a bioretention facility. Stormwater pollutant mitigation is accomplished through phytoremediation processes as runoff passes through the plant and soil community. Rain gardens combine layers of organic sandy soil for infiltration, and mulch to promote microbial activity. Native plants are recommended based upon their intrinsic synergies with local climate, soil, and moisture conditions without the use of fertilizers and chemicals. Rain gardens are best applied on a relatively small scale. They work well along driveways and in low
lying areas of a property.
Rain gardens should be located at least 10 feet away from buildings to prevent water seepage into foundations or underneath houses, causing mold and mildew problems. Also, location away from large trees allows exposure to sunlight so that
rain gardens may dry out between storm events.
