GREENLINE GOALS: -Re-activate unused infrastructural space within the Hollygrove neighborhood -Educate the community on stormwater management strategies -Provide healthy, safe, enjoyable public outdoor spaces -Provide demonstration gardens for urban farming initiatives

STORY HISTORY HISTORY

HISTORY

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.

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 communityâ&#x20AC;&#x2122;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.

Tree Nursery Irrigation Demonstration

Entrance on Leonidas Street 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.

Recent 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 development, further enhancing the CDCâ&#x20AC;&#x2122;s educational goals.
