What Will It Take to Make the CHARM Gateway a Walkable Urban Center?

The short version: connect the streets, shrink the blocks, and make it easier to get around on foot, bike, or transit.

The Capitol Heights–Addison Road Metro (“CHARM”) regional activity center has two Metro stations, sits inside the Beltway, and lies just minutes from the District of Columbia. So what will it take for this area to transform into the walkable urban center that regional plans have long envisioned? 

More retail? More housing? More places to work and play? Yes, absolutely—but first, we have to get the street grid right.

Places that work well for everyday life tend to share a few basic traits: connected streets, relatively compact blocks, and the ability to move easily on foot, by bike, or by transit—not just by car.

These features are the structural foundations of successful urban neighborhoods. Where they exist, communities attract investment, support local businesses, and become places people want to live. Where they do not, even strong markets often struggle to perform.

This reality sits at the heart of the Transportation Infrastructure and Economic Development (“TIED”) planning work now underway for the CHARM Gateway.

The Hidden Infrastructure of Successful Neighborhoods

When people think about infrastructure, they usually picture highways, rail lines, or utilities. But one of the most important forms of infrastructure is the local street network itself.

Street networks shape how people move through a place, how businesses attract customers, how land can be developed, and how comfortable everyday life feels.

In successful urban districts—from historic city centers to newer transit-oriented communities—the pattern is remarkably consistent:

• Streets connect frequently.

• Blocks are relatively short.

• Multiple routes are available between destinations.

• Buildings front onto streets where people walk.

Planners sometimes call this “network connectivity.” For residents and visitors, it simply feels like a place that works.

In contrast, places with disconnected streets, oversized blocks, or dead-end roadways often struggle to function as walkable communities. Even when they have strong regional advantages—such as proximity to transit or employment centers—the physical structure of the area can prevent those advantages from translating into everyday economic vitality.

The Quiet Power of Block Size

One of the most overlooked elements of urban design is block length.

Shorter blocks create more intersections and more route choices. That means pedestrians can take direct paths rather than walking long distances around large parcels or superblocks. It also means businesses gain more visible frontages along the street network.

The difference can be dramatic.

In walkable environments, typical block lengths often fall within the range of roughly 150 to 300 feet. These dimensions make it easy to move through an area and allow development to occur on a human-scaled pattern.

When blocks become extremely long—600 feet or more—walkability begins to break down. Pedestrians face long detours, development parcels become harder to subdivide, and fewer locations exist where shops, restaurants, or community spaces can interact with the street. Prince George’s County’s Plan 2035 makes the same point, noting that compact blocks in roughly this range are essential to creating pedestrian-friendly environments.

In short, block structure quietly shapes the economic and social life of a neighborhood.

The Relationship Between Streets and Local Economies

Street networks do more than move traffic. They shape economic opportunity.

Small businesses depend on visibility and accessibility. Restaurants rely on foot traffic. Neighborhood services succeed when customers can reach them easily during the course of daily life.

A connected grid creates many possible paths through a district, increasing the number of potential customers passing storefronts each day and distributing activity across multiple streets rather than a single high‑traffic corridor.

Where the grid is missing, economic activity often concentrates in isolated clusters or along large arterial roads designed primarily for vehicle movement. Those environments can make everyday urban life feel fragmented and discourage the kinds of local businesses that make neighborhoods vibrant.

Getting Around Without a Car: Walking, Biking, and Transit

Transit-oriented communities succeed when the areas around stations are easy to navigate on foot, by bicycle, or using assistive devices for people of all ages and abilities. In places that work well, everyday trips—grabbing coffee, picking up groceries, meeting friends, or getting to work—can often be done without needing to drive.

Even excellent rail or bus service cannot fully compensate for a street network that is difficult to navigate without a car. Long blocks, missing connections, or disconnected street patterns increase walking distances and reduce the number of destinations reachable within a comfortable five- or ten-minute walk.

By contrast, compact blocks and interconnected streets expand the reach of transit stations. More homes, businesses, and community spaces fall within a convenient walking or biking distance, allowing transit to support everyday life rather than serving only commuters.

For regions seeking to grow sustainably while improving affordability and access to opportunity, this relationship between multimodal mobility and transit becomes especially important.

And Yes—Street Grids Are Better for Cars Too

It may sound counterintuitive, but connected street grids are usually better for local drivers as well.

When a street network offers many routes between destinations, traffic can spread across multiple streets rather than concentrating on a few overburdened corridors. In a grid, a driver may have three or four reasonable ways to reach the same destination; in a superblock pattern, nearly every trip is forced onto the same arterial roads. Drivers gain options, congestion becomes less severe at any single point, and local trips can be completed more efficiently.

By contrast, areas dominated by superblocks and disconnected streets tend to funnel nearly all traffic onto a handful of major roads. That pattern often produces the stop‑and‑go congestion familiar on many suburban arterials, even when the overall number of trips is relatively modest.

In other words, a connected street network does not just improve walkability. It creates a transportation system that works better for everyone.

Capitol Heights-Addison Road Metro Regional Activity Center

Why This Matters for the CHARM Gateway

The CHARM Gateway occupies one of the most strategically located geographies in Prince George’s County. With two Metrorail stations inside the Beltway and just minutes from the District of Columbia, it has the potential to function as a true downtown for Greater Capitol Heights—a walkable, bikeable center of activity, commerce, and community life anchored by transit.

Yet despite these advantages, the area has not developed the kind of walkable, mixed‑use district many regional plans have envisioned. One reason is the physical structure of the area itself. Portions of the CHARM Gateway are defined by fragmented street patterns, oversized blocks, and limited internal connectivity, which makes it difficult for the area to function as a coherent urban center even though the market potential exists.

The TIED planning effort focuses on addressing those structural challenges. Rather than concentrating only on individual development projects, it looks at how transportation infrastructure, land use, and economic development must work together to create the conditions for long‑term success. At the center of that approach is a simple idea: thriving urban districts depend on a connected street grid and compact, walkable blocks.

Planning for Long-Term Urban Performance

For the CHARM Gateway, the central challenge is straightforward: the area was not originally built around a connected street grid. Large blocks and fragmented streets make it difficult for the district to function as a walkable urban center.

Retrofitting that network—connecting streets and breaking up oversized blocks—is therefore essential to the long‑term success of the area. The purpose of the TIED initiative is to address that underlying structural gap.

By gradually rebuilding a connected street network and aligning transportation, land use, and economic development strategy, the CHARM Gateway can begin to function as the true downtown for Greater Capitol Heights—an active, walkable center for residents, businesses, and visitors alike.

Retail, housing, offices, and public spaces can grow around that framework. But for the CHARM Gateway to succeed over the long run, the street grid has to come first.
