 # Clean & Green Philly
 
-Philadelphia has a gun violence problem. This dashboard aims to help solve it by empowering community groups to carry out cleaning and greening interventions in the vacant properties where they can have the biggest impact.
-
-## Motivation
-
-Philadelphia has a gun violence problem. Homicides have been on the rise since 2013. The past three years—2020, 2021, and 2022—have been the deadliest on record, with a high of 562 homicides in 2021. Community members need solutions, but many city-run initiatives are frustratingly slow or inadequate. Nearly 80% of the city’s anti-violence spending focuses on long-term violence reduction without any clear, immediate impact.
-
-Research shows that greening and cleaning vacant and abandoned parcels is one of the most impactful, cost-effective interventions available to reduce gun violence in a neighborhood. Drs. Eugenia South and Charles Branas have led several studies that [demonstrate that greening vacant lots in Philadelphia reduced gun violence by as much as 29% in the surrounding area](https://www.pnas.org/doi/10.1073/pnas.1718503115). Similarly, cleaning and lightly repairing vacant houses led a 13% drop in gun assaults compared to nearby blocks. These “greening and cleaning” interventions not only reduce gun violence but also provide other benefits, such as reducing the urban heat island effect, lowering residents’ stress levels, and contributing to lower levels of depression among residents.
-
-There are roughly 40,000 vaccant properties in Philadelphia. Identifying the highest-priority vacant properties will allow community groups to invest their limited resources where they will have the biggest impact. Combining various public data, this dashboard helps users identify the properties that are ideal for them to intervene in. It also offers additional information about each property to facilitate interventions and indicates the best possible route to cleaning up the property.

-You can view [the current build of the website here](https://www.cleanandgreenphilly.org/). We are building based off of a prototype which looks like this:
+🚨 Project Status
 
-![User prototype map](/docs/map.png)
+_Note: Clean & Green Philly ceased active development and maintainence in July of 2025. For more information, please see our [letter to stakeholders](/docs/PROJECT_BACKGROUND/C&GP%20Shutdown%20Letter,%20June%205,%202025.pdf) from July 2025. The website is still available at [cleanandgreenphilly.org](https://www.cleanandgreenphilly.org/) and the site, codebase, and data will remain available and open source for the foreseeable future._
 
-An older proptotype is also [available here](https://nlebovits.github.io/dashboard_demo_website/more_info.html), although it is now significantly out of date.
-
-Likewise, you can view the [very first iteration as an ArcGIS Storymap here](https://storymaps.arcgis.com/stories/551f77d85a584705b97c41db7711ba1b).

-## Project Updates
-
-**May 1, 2024:** Clean & Green Philly won second place in the [36th annual NJ DEP Mapping Contest's](https://dep.nj.gov/gis/36th-mapping-contest/) Dashboard category!
-
-**April 26, 2024:** On behalf of Clean & Green Philly, Nissim gave testimony to a Philadelphia City Council hearing on the uses of data and tech to reduce gun violence through place-based interventions. His statement is [available here](/docs/PROJECT_BACKGROUND/City%20Council%20Testimony%20Final,%20April%2026,%202024.pdf).
-
-**April 21, 2024:** We have officially launched v1.0.0! The website is now live at [www.cleanandgreenphilly.org](https://www.cleanandgreenphilly.org/).
-
-**Feb. 1, 2024:** We have soft launched a minimum viable product! The website is functional at [www.cleanandgreenphilly.org](https://www.cleanandgreenphilly.org/).
+Philadelphia has a gun violence problem. This dashboard aims to help solve it by empowering community groups to carry out cleaning and greening interventions in the vacant properties where they can have the biggest impact.
 
-**Nov. 15, 2023:** The Center for Philadelphia's Urban Future has officially voted to be a fiscal sponsor for our project and maintain it long-term. We are working with them to assemble a steering committee that will help inform future development of the web tool.
+For more information on the research and data behind the project, please see the background information in [our docs](docs/).
 
-**Oct. 2, 2023:** Met with the Philadelphia District Attorney's Office data analytics team. They are very excited about the dashboard and are connecting us with folks in the Managing Director's Office and the Civic Coalition to Save Lives.
+## Data Access
 
-**Sept. 29, 2023** Got our first funding from a donor! He's writing us a check to cover costs associated with user testing, hosting, domain name, etc., and will connet us with other folks who may be willing to give us more.
+All of our final output data, including final backups of the last reasonably valid vacant properties data, are available in [our `data` subdirectory](/data/backup_data/). There, you will find the backup vacant properties data, along with a GeoParquet file containing our last data outputs from July 2025 and a PMtiles dataset that we use for visualizing the vacant properties on the website. A README in the folder gives more context on the data.
 
-**Sept. 27, 2023** Nissim spoke with a reporter from WHYY who may be including our project in a longer piece about Philadelphians working on solutions to the gun violence crisis.
+Anyone interested in generating new data can simply install the codebase and run the pipeline via Docker, provided they bear in mind that everything _but_ the vacant properties data will be up to date.
 
-## Current Tasks and Project Roadmap
+## Project History
 
-At the moment, we are working on:
+### 2025
 
-- Organizing a steering committee of stakeholders to guide future project development
-- Improving the accessibility and responsiveness of our MVP
-- Improving the content and design of our Take Action pages
-- Laying groundwork to apply for a grant to support our work
+**July 2025:** Clean & Green Philly ceases active development due to a lack of available data on vacant properties in Philadelphia.
