Data Drives Housing, Planning Decisions in Baltimore
Source: GovTech | By Stephen Goldsmith
To support its goals and revitalize neighborhoods, the Baltimore City Department of Housing and Community Development uses GIS and location data that keeps records up to date and transparent for all stakeholders.
Comprehensive approaches to complex urban problems require comprehensive data, and the actions of the Baltimore City Department of Housing and Community Development (DHCD) demonstrate why and how. The department oversees permits, code enforcement, development and homeownership support programs. By integrating these responsibilities, housing officials believe they can better understand trends and leverage resources to revitalize neighborhoods suffering from historic disinvestment.
In 2019, DHCD released a comprehensive Framework for Community Development, which outlines an investment strategy that is:
Asset-based, meaning investments are prioritized in areas near high-value community assets such as schools, hospitals, etc.;
Place-based, meaning they are focused on building and strengthening entire communities, utilizing an equity lens; and
Whole-block-based, meaning they are focused on outcomes at the block or neighborhood level and not on individual homes or apartments.
“‘Building from strength’ is our tagline,” said Kimberly Rubens, acting chief of policy and partnerships and director of research and analytics for DHCD. With these priorities in mind, the framework identified seven areas spanning 22 neighborhoods across Southeast and Southwest Baltimore, chosen because of their proximity to an anchor for development activity and because they have strong community partnerships.
To support the framework’s goals, DHCD has turned to GIS and location intelligence. Michael Braverman, the head of code enforcement for DHCD at the time, wanted access to a robust GIS tool to be able to leverage information about homes and neighborhoods. Braverman and two of his colleagues developed CoDeMap Classic and then built a 2.0 version with increased mapping options. Together they allow users to find up-to-date information about a property, including sale history, floodplain status, permit and citation history, and rental licensing status, as well as zoning data. Staff now use the platform to inform building or neighborhood interventions such as demolitions.
DHCD has developed a community planning layer on CoDeMap that enables long-term, block-by-block planning directly on the platform. The user-centric 2.0 reforms include thematic grouping of the layers and a range of tools including an application that remembers each user’s preferred GIS layers.
According to Rubens, the CoDeMap platform “allows us to move from the theory of the framework to the practice of actually going into these communities to do the investment work.” The ability to layer data allows DHCD to take insights and discuss priority projects with community representatives in order to identify those with the most potential for positive whole-block outcomes.
Technology facilitates demolition planning, as well as department planning and community engagement and awareness. Community policing takes advantage of mapping to do property-level research for high-profile illegal activities that might be taking place.
The GIS team conducts extensive outreach and training, helping expand the scope and impact of the applications. After the major update in 2020, DHCD trained 500 users in the first few months, and continues to conduct regular trainings to ensure city staff maintain the skills they need to access and navigate the application.
These components of Baltimore’s successes serve as helpful lessons. The project utilized data from various departments and combined it with the end user in mind through map data visualizations that broadly produced insights. Extensive…
