Introduction 

Just as in the rest of the country, Maryland is experiencing a housing crisis as home and land prices continue to rise faster than incomes. This is caused by the shortage of homes available to residents at all incomes, particularly those with low or very low incomes. This challenge is further compounded by the necessity of a car to access jobs and housing. This auto-oriented environment leads to houses and amenities being widely dispersed, resulting in increasing carbon emissions, environmental degradation, and traffic deaths. The low-density character of housing development has also been associated with higher housing costs, making the affordability crisis worse. Given these myriad issues, planners and state agencies have an understandable interest in finding strategies to rapidly build housing without adding to an over-stretched transportation system. 

Transit-oriented development (TOD) is one such strategy, presenting a viable alternative to sprawl  by pairing denser, more affordable housing with convenient access to public transportation. Typically occurring within a 10-minute walkshed, or approximately 1/2 of a mile, from a transit station, TOD is characterized by mixed-use, dense development which offers residents a variety of transportation options alongside reduced traffic congestion, economically revitalized neighborhoods, and increased affordable housing production, amongst other benefits. TOD has been remarkably successful in the DC metro area, with the Rosslyn-Ballston corridor along the WMATA rail network in Arlington, Virginia having contributed to over 25% of the County’s entire growth between 1990-2000, and currently being home to over 47,000 people and 42 million square feet of commercial space.

Accordingly, it is a well-understood priority by the State of Maryland to advance TOD, and this requires understanding the existing land use character surrounding transit stations in the state. Our research at NCSG has accomplished just that, by using the State Department of Assessments and Taxation (SDAT)’s PropertyView database to create an interactive map of all state-owned land within a 1-mile radius of a transit station. We find significant potential for new development, particularly in the suburban counties of Washington, Montgomery and Prince George’s, owing to that region’s robust rail system, WMATA. We also find notable development potential in Baltimore City and County through partnering with MDOT along the Baltimore Metro Subway and Light Rail Lines.

Methodology

This project originally began with an exploration of the State’s PropertyView System, which laid the groundwork for much of our subsequent analysis. This first step in this exploration was the creation of 1-mile buffers around the 111 different rail transit stations in Maryland, including 26 on the WMATA system, 38 on MARC, 14 on the Baltimore Metro, and 33 on the Baltimore Light Rail, using ArcGIS Pro. Within those buffer zones, properties were then identified and their owners classified to understand land distribution. Properties not determined to belong to either federal, state, county, or municipal governments were excluded at this stage, using listed owner names in the original dataset. Land use code descriptors were also used to further refine the ownership dataset. We also excluded properties with certain listed uses, such as airports, parks, and schools, as those are unlikely to be redeveloped for additional housing or converted from their existing uses. Our full list of codes used for defining target parcels can be found in the data dictionary, and is based off of the SDAT Exemption Class code. Next, the presence of duplicate parcels and layers was handled by deleting parcels with shared IDs, and inconsistent ownership naming conventions, such as the 14 different listings of the Washington Metropolitan Area Transit Authority, WMATA, was handled through the reclassify tool of ArcGIS Arcade. Finally, the various separate layers for each county were merged to create a single layer, and public parking lots not previously identified were found and merged to this master layer.

The creation of the interactive map necessitated the use of ArcGIS Experience Builder, and it possesses many features designed for an intuitive user interface. The attribute table was reorganized to only include relevant fields, such as Owner Name, Address, and County. A Filter by County tool was added, which allows users to zoom into and select target counties. This tool also affects a pie chart, which is displayed alongside the layer’s attribute table and can be seen when clicking on the bottom panel of the web map. This pie chart displays the acreage within a county, or the State as a whole, organized by owner, and provides a useful summary for ownership trends across the State. The map also possesses various other layers, such as buffers, county and transit lines, and flood zones, designed to enhance user understanding and provide a more robust picture of the state of public land ownership near transit in Maryland. Lastly, the map is able to be exported and printed in a Letter ANSI A Landscape format, so it can be shared physically as well as digitally.

Preliminary Findings

The most significant finding from this project was that WMATA owns a sizable majority (65%) of public land within our transit buffer zones, indicating that the suburban counties of Washington, Montgomery and especially Prince George’s, have the greatest potential for transit-oriented development. Indeed, WMATA owns more land in Prince George’s County (754 acres) than all other public entities combined own across all counties, including Prince George’s (593 acres). This is apparent when looking at stations such as Morgan Boulevard on the blue line, Branch Avenue on the green line, and New Carrollton on the orange and future purple lines, which are surrounded by potentially developable WMATA land. 

Montgomery County, while not possessing the same extent of public land near transit as Prince George’s, still has significantly more public land near transit than any other county in the State. Almost 80% of that land (370/463 acres) is owned by WMATA. This indicates that Montgomery County should also pursue partnerships with the transportation authority to bring in new development on those stations, which can increase the availability and affordability of housing within the region. The recent announcement of new development on the North Bethesda metro station, along the Red Line, represents a positive development pursuant to this goal.

The Baltimore region also has significant potential for transit-oriented development, with the City having approximately 14 more acres of land available than Baltimore County (100 vs 86). Both governments should seek to partner with MDOT to pursue redevelopment, as it owns over 80% of the land available for redevelopment in the combined region. Baltimore City currently has provisions in its zoning code explicitly designed for TOD, and these zones can be applied alongside other incentives to spur new activity and housing near stations in the downtown core of the city. 

Next Steps

While the work done so far represents a significant improvement in our understanding of the feasibility and availability of publicly-led transit-oriented development, more research is needed to ensure the viability of these sites. We are currently working on classifying these parcels as being partially, wholly, or not at all in a floodplain, as this characteristic is critical in determining the true viability of redevelopment projects. Likewise, we are exploring a classification of these parcels by zoning category to complement our ownership analysis. Zoning is the legal framework in which development occurs, and so parcels that are not zoned for TOD are unable to be fully utilized. We will also identify the distribution of this land by Maryland’s legislative boundaries. We will continue to revisit parcel identification and classification, as it is possible that our reliance on the SDAT PropertyView system has led to some parcels being accidentally excluded from our analysis, and others being incorrectly included.

New Research on “Studentification” in College Park

Introduction 

The term “studentification, coined by Darren P. Smith describes the economic, social, cultural and physical transformations that occur in University towns due to an increasing concentration of students. Unlike traditional gentrification which involves an influx of wealthier residents displacing lower-income populations, studentification is unique in that it is driven by a transient, relatively low-income student population. Despite their temporary status, students impact local housing markets by raising rental prices, increasing demand for shared accommodations, and driving conversion of single-family homes into student rentals. The commercial landscape also shifts, as businesses reorient themselves to cater to student needs. Beyond these market impacts, studentification reshapes the cultural and social fabric of neighborhoods, often leading to increased noise complaints, maintenance issues, and the self segregation of students from long-time residents. 

Studentification can already be seen as having occurred in College Park, which has seen a notable decline in the rate of owner-occupied housing, signaling what could occur on the rest of the Purple Line.

College Park, Maryland, home to the University of Maryland (UMDCP), has long struggled with its identity as a college town. For decades, the city was known more as a commuter hub than a vibrant student-friendly community. However, over the last 20+ years, efforts to change this reputation have intensified. The Greater College Park initiative, launched in 2016, represents a significant step in reshaping the area into a “vibrant, diverse, and walkable” community. This vision includes the redevelopment of the Baltimore Avenue corridor, including new housing, retail spaces, and commercial investments. This intensification of near-University development is complemented by the arrival of the Purple Line, a new light rail system connecting Prince George’s and Montgomery Counties. The new 16.2 mile light rail will dramatically improve transit access for students, faculty and local residents. While these developments promise connectivity and transit oriented development, they also raise concerns about displacement, affordability and neighborhood change as rising rents have already been observed along the corridor. This research examines how studentification, the University of Maryland, and the Purple Line stand to collectively transform College Park. 

Local Development Context

College Park’s evolution into a more traditional college town has been driven by a strategic effort to increase investment and development in the area. Historically, the city struggled with a lack of amenities and infrastructure that catered to students and faculty, leading many to live and socialize elsewhere. In response, the University of Maryland and its development partners have spearheaded the Greater College Park Initiative, securing over $2 billion in public-private investment to reshape the area. These efforts are largely led by the Terrapin Development Company (TDC), the College Park City University Partnership, and the Office of Real Estate, which has played a central role in bringing in new businesses, housing, and research facilities.

Their investments include the creation of the Discovery District, a mixed-use research and innovation hub designed to attract corporate partners and boost local economic activity. Additionally, the construction of new high-rise student housing and retail spaces along Baltimore Avenue has transformed the city’s central thoroughfare, replacing older, low-density structures with modern developments aimed at fostering a more dynamic and pedestrian-friendly environment. Another notable project is the new City Hall, a joint initiative between UMD and the city, which serves as a hub for municipal offices, university operations, and community engagement. 

While these developments have brought significant investment to College Park, they also raise concerns about their broader impact on the existing community. Rising property values and increased demand for student housing have the potential to drive up rents and displace long-time residents, particularly in areas along the Purple Line corridor. Additionally, as businesses shift their focus toward serving the student population, long-established local businesses may struggle to compete. While the university’s expansion efforts aim to create a thriving college town, ongoing attention is needed to ensure that growth is equitable and inclusive, preventing the negative consequences of unchecked studentification.

Key Results

Turning first to the demographic trends which have occurred along the Purple Line and within College Park, the census tracts along the corridor’s walkshed recorded a significant increase in their racial diversity from 1980 onward. Figure 2 demonstrates this growth, highlighting the presence and establishment of Hispanic communities in particular, which saw an increase from just under 10,000 people in 1980 to nearly 80,000 by 2023, becoming the largest single ethnic group along the corridor. The non-Hispanic Black population also displays growth over time, primarily over the time period from 1980 through 2000, which is when the population peaks. It is interesting to note that the era of population loss, from 2000 to 2010, is when the 2000 Silver Spring CBD Sector Plan was adopted, which catalyzed redevelopment locally while also causing the local Ethiopian community struggling to endure the subsequent rent hikes. Regardless, the Black community remains a strong and notable population along the Purple line, and diversity is critical for the corridor at large.

Our analysis of longitudinal census data also found that increases in home values significantly outpaced both increases in rents and incomes, with the former increasing by just 13% from 1980 through 2023, while rents increased by 66% and home values by 73%, after the data were adjusted for inflation. These findings show that housing along the corridor has become significantly less affordable, increasing the pressure on low-income residents. Finally, while the data showed no significant change in owner occupancy rates for the corridor as a whole, College Park specifically recorded a 21% decline in owner-occupied housing from 1980 through 2023, providing evidence that an increasing number of housing units are now converted student rentals, and that studentification is occurring.

Data adjusted for inflation

Turning now to our analysis of student housing patterns we found notable student populations of students currently living in the census blocks around the Greenbelt, Hyattsville Crossing (PG Plaza), and Silver Spring metro stations, as shown in the map below. This indicates an underlying student willingness to commute to campus by transit, which is significant given that a large number of students live over 5 miles away and likely are predominantly car-dependent commuters. The reasons to choose transit may include a desire to avoid parking costs (which can exceed $350 for commuters, and $700 for on campus residents), safety (WMATA reported just 20 customer injuries in 2024, compared to 6,000 traffic-related injuries in 2023), or simple convenience (drivers regularly experience more stressful commutes). Regardless, the data shows an existing underlying student demand for transit, which may fuel demand for more housing along the Purple Line.

Finally, our analysis of student housing patterns revealed that the Purple Line will dramatically increase metro transit-accessibility for students. While currently just over 2,000 students live within such a 15-minute walk of a metro station, the completion of the Purple Line and its 5 stations on or near campus will result in over 16,000 students living within the walkshed, a nearly 650% increase. One operational, the almost-overnight changes in transit accessibility could bring more substantial changes in student housing and commuting preferences.

Discussion

Given the results above, we can expect that more students will seek to move-in along the Purple Line corridor once it is completed as it will provide rapid access to campus. This is particularly relevant to students who commute by car, as student-friendly transit-accessible neighborhoods already exist as described above. As the Greenbelt and Hyattsville Crossing stations are just one stop away from a transfer onto the future Purple Line, and the Silver Spring station will have a transfer platform for the Purple Line, student populations in these areas, and other neighborhoods in between, are likely to increase. As mentioned previously, adopting more transit-oriented commuting patterns will save students hundreds of dollars in parking, insurance, gas, and other fees associated with car use, and this could prove to be a powerful incentive in changing their housing patterns. 

With respect to the large proportion of on-campus students now able to access the Purple Line corridor by transit, we can expect these students to become important patrons for businesses along the way. This may result in the studentification of the corridor, as businesses need to cater to student preferences. Studentification can already be seen as having occurred in College Park, which has seen a notable decline in the rate of owner-occupied housing, signaling what could occur on the rest of the Purple Line. This may result in transit-induced displacement, as the student housing patterns described above may result in increased competition for rental units. The slower increase in rents when compared to home values, described earlier, has resulted in them serving as a vital, more affordable housing option to the low and moderate-income residents of the majority Black and Brown community which currently exists along the corridor. Increased competition and attractiveness of the land is likely to drive up those rents significantly, and could result in the displacement of vulnerable residents

At the National Center for Smart Growth (NCSG), we plan on continuous future monitoring of the Purple Line to determine if such displacement is occurring. Future research may also investigate permit data to see how the real-time effects of increased student demand on housing and businesses, the level to which students may save money through switching from car-transport to public transit, and conduct qualitative analyses on student attitudes towards the Purple Line and its housing implications. Ultimately, we are committed to ensuring that all can enjoy a sustainable and vibrant quality of life, through community-centered research, collaborative action, and advocacy, and our future work investigating studentification along the Purple Line will continue to do just that.
