 Hollygrove was once a piece of the McCarty plantation, grew out of the town of Carrollton, a suburb outside of New Orleans. Before the 1920s, when development began, Hollygrove was a low-lying swamp land, essentially untouched and unoccupied. Drainage systems installed in the 1920s allowed for housing to be built, although these systems never proved effective. In the 1960s, drainage methods were reworked to be more reliable, allowing for more housing to be developed. Even before effective drainage was implemented, Hollygrove grew drastically, the effects of which are still visible today. The Greater New Orleans Community Data Center that, pre-Katrina, nearly fifty percent of Hollygrove’s houses were built before 1949. Similarly, before Katrina, over half of the homes in Hollygrove were owner-occupied.
When Hurricane Katrina breached the levees of New Orleans, Hollygrove began to flood, taking in water. Persevering, Hollygrove’s community has returned with great strength – the Louisiana State University survey on contractor fraud reported that Hollygrove/Gert Town’s recovery of residence was high; on a scale from 1 (lowest recovery of residence) to 11 (highest), Hollygrove and Gert Town were placed at a 9. The neighborhood is home to generations of families, creating a strong sense of place and community. Rebuilding Together is proud to partner with the Trinity Christian Community, based in Hollygrove, in order to build a relationship with the neighborhood and facilitate its growth.

 In the 1970s Hollygrove had been known to have a very high poverty, crime, and homicide rate. Shortly after crack cocaine hit the streets, NOPD waged war with drug dealers that dominated Hollygrove. By the 1980s and 1990s, gunfire was a constant fact of Hollygrove life. The overall crime rate in Hollygrove at the time was 136% higher than the national average. For every 100,000 people, there were 19.15 daily crimes that occurred in Hollygrove. The number of total year over year crimes in New Orleans had increased by 12%. However since the early 2000s the neighborhood has experienced a great deal of change and revitalization and crime rates have dropped dramatically. In the last decade the area has become a welcoming and diverse neighborhood of working class individuals from all walks of life and property values and new home construction has increased dramatically. The Hollygrove neighborhood is a prime example of the vibrant and diverse possibilities of New Orleans. The new and expansive Ochsner Medical Complex Campus is just over the Orleans/Jefferson Parish line and is a major employer and benefit to the area.
