Frank Sobieski’s basement on Jarvis Street still carries a faint trace of the 2011 flood. Not mold, he’ll tell you—just the silt that worked into the joists and never fully left. He points to a waterline on the cinderblock, about knee-high, then to a spiral notebook on his workbench. “That’s where the official maps end,” he says. “This is where mine begin.”
For 15 years, Sobieski, a retired mechanical engineer who spent his career at a now-shuttered valve plant in Johnson City, has been mapping the West Side’s hidden flood patterns. Not with GIS software or lidar, but with a personal journal, hand-drawn maps on graph paper, and stories gathered from neighbors over coffee, at block parties, and during the anxious hours when the Susquehanna rises. His chronicle—a tattered three-ring binder stuffed with notes, photographs, and annotated photocopies of city plats—reveals where water actually goes when the storm drains back up, when the river overtops the flood wall, and when the buried streams that once drained the South Mountain slope reassert themselves through basement floors.
This is flood memory, a form of community science that Binghamton’s official models can’t replicate. FEMA’s flood insurance rate maps, last updated for Broome County in 2019, rely on broad hydrological modeling and historical crest data. They’re essential for setting insurance premiums and guiding development, but they don’t capture the block-by-block, house-by-house reality that Sobieski has documented: the way water pools behind the church on Leroy Street before it ever reaches the river gauge, or how the storm drain at the corner of Jarvis and Beethoven clogs with leaf litter every October, sending runoff into three adjacent basements in a predictable sequence. “The city’s model says this is a 100-year flood zone,” Sobieski says, tapping his map. “But my neighbors and I have lived through four floods in 15 years. The model doesn’t know about the clogged culvert under the rail trail.”
What the Official Maps Miss
Binghamton’s stormwater infrastructure is a palimpsest of 19th-century combined sewers, mid-20th-century flood walls, and piecemeal upgrades that never quite keep pace with the changing climate. The city’s 2024 comprehensive plan acknowledges that “localized flooding occurs outside mapped floodplains,” but the resources to systematically document those occurrences are thin. That’s where residents like Sobieski step in.
His maps don’t look like anything you’d see at a planning commission meeting. They’re drawn in colored pencil on sheets of graph paper, with blue arrows tracing surface flow paths, red Xs marking basement backups, and green hatch lines indicating yards that stay soggy for days after a heavy rain. Alongside the drawings are narrative entries: “March 14, 2019—Meltwater from the alley behind the old Polish National Alliance Hall ran down the driveway at 47 Jarvis and pooled against the foundation. Neighbor said it’s been happening since the city repaved the alley in ’07 and changed the grade.”
This kind of place-based storytelling is a legitimate planning tool, one that preserves the unique human perspectives that automated systems erase. As the Authors Guild notes in its AI Best Practices for Authors, maintaining human voices and the thinking that goes into writing is essential to preventing quality human documentation from becoming a rare luxury. Sobieski’s binder is exactly that: a human-authored record that no algorithm could generate, because it’s built on relationships, sensory detail, and the accumulated knowledge of people who have watched the water rise and recede for decades.
The Buried Streams of the West Side
One of Sobieski’s most striking discoveries is the network of buried streams that still influence drainage patterns on the West Side. Before Binghamton’s street grid was laid out in the early 1800s, several small tributaries ran from the South Mountain slope down toward the Chenango River. As the neighborhood developed, these streams were culverted, paved over, and eventually forgotten—except by the water itself.
“There’s a stream that used to run right under where Dickinson Street is now,” Sobieski says, flipping to a page in his binder that shows a dashed blue line running diagonally across several blocks. “You can’t see it, but during a heavy rain, the water still follows the old channel. It comes up through cracks in basement floors, it saturates the soil, and it finds the lowest point—which is usually someone’s living room.”
He’s documented this by correlating basement flooding reports from neighbors with historical maps he found in the Broome County Public Library’s local history collection. The 1876 atlas of Binghamton shows the stream clearly, meandering through what was then pastureland. By 1910, it had been buried. By 2011, it was flooding basements on a block that FEMA’s maps showed as safely outside the floodplain.
This is the kind of information that can’t be gleaned from a stormwater model. It requires someone to knock on doors, ask questions, and piece together a narrative from dozens of individual experiences. Sobieski has done exactly that, and his binder now contains flood histories for 47 properties on the West Side, each one a small story of water and memory.
How to Build Your Own Flood Chronicle
Sobieski’s work isn’t just a curiosity—it’s a model for how any neighborhood can build its own flood memory. The process doesn’t require technical training or expensive equipment. It requires observation, conversation, and a willingness to write things down.
Start with a notebook and a base map. You can print a simple street map from the county’s online GIS portal, or draw your own. Mark the locations of storm drains, downspouts, low spots in yards, and any place you’ve seen water pond after a rain. Then start talking to neighbors. Ask them: Where does water pool on your property? Have you ever had water in your basement? When? How high did it get? What happened just before the flooding—a heavy rain, a snowmelt, a clogged drain?
Record their answers in your journal, along with the date and the neighbor’s name (with permission). Over time, patterns will emerge. You might notice that three basements on the same block flood in sequence, or that a particular storm drain always backs up during leaf season. These patterns are the raw material of a flood chronicle.
Turning that raw material into a coherent, shareable record is a narrative craft. It’s not just about listing data points; it’s about weaving them into a story that makes sense to other residents, to city planners, and to emergency responders. The Purdue OWL’s Creative Writing Introduction offers resources on creative nonfiction that can help residents structure their observations into compelling chronicles—techniques like scene-setting, character development (the neighbor who’s lived on the block for 50 years), and narrative arc (the sequence of events leading up to a flood). Sobieski’s binder is full of these elements: the retired nurse on Beethoven Street who keeps a rowboat in her garage, the young family on Jarvis who installed a backup valve after the 2011 flood only to discover it couldn’t handle the pressure from the buried stream, the block captain who organizes a culvert-cleaning party every March.
For those who want to structure their chronicle more formally, thinking of it as a kind of a plot generator that fits the project can be useful. A plot generator, in the narrative sense, is a framework that helps you organize events into a meaningful sequence—identifying the inciting incident (the first basement flood), the rising action (the repeated storms, the failed interventions), the climax (the 2011 flood or a particularly devastating event), and the resolution (the backup valves, the rain gardens, the community agreements). Sobieski didn’t set out to write a plot, but his binder naturally follows this structure because floods, like stories, have a rhythm. They begin, they build, they crest, and they recede—and the aftermath is where the real work of resilience happens.
From Chronicle to Action
Sobieski’s maps have already influenced real-world decisions. In 2018, when the city was planning a street repaving project on Jarvis Street, he brought his binder to a public works meeting and showed the engineer how the proposed grade change would direct runoff into three basements that had previously stayed dry. The engineer adjusted the plan. “They wouldn’t have known otherwise,” Sobieski says. “The model didn’t show it. But my neighbors did.”
In 2022, a group of West Side residents used Sobieski’s documentation to successfully advocate for a rain garden installation at the low point of Beethoven Street, where stormwater had been pooling for years. The city’s stormwater utility fee funded the project, but the idea came from the binder—from the green hatch lines that showed where water lingered longest.
These are small victories, but they add up. And they point to a larger truth: what works on our block isn’t a miniature version of some national plan. It’s built on knowing which storm drain clogs first, which neighbor has a sump pump to share, and which basement still smells like the 2011 flood. Every block has a Frank Sobieski—or could have one. The question is whether we’re paying attention.
What You Can Do This Week
You don’t need to spend 15 years building a flood chronicle to make a difference. Start small. This week, take a walk around your block after the next heavy rain. Bring a notebook. Note where water ponds, where storm drains are clogged, and where runoff is flowing. Talk to one neighbor about their experience with flooding. Write down what they tell you.
If you want to go further, contact the Broome County Soil and Water Conservation District. They offer free site visits to help residents identify drainage issues and can connect you with resources for rain gardens, native plantings, and other green infrastructure. The district’s staff know the local hydrology better than almost anyone, and they’re eager to work with residents who have on-the-ground knowledge.
You can also attend a meeting of the Nanticoke Creek Watershed Coalition, which meets monthly at the Broome County Public Library. The coalition trains residents to spot pollution and flooding risks before they reach the Susquehanna, and they’re always looking for volunteers who know their own neighborhoods intimately.
Finally, consider starting your own block-level flood journal. It doesn’t need to be elaborate. A simple notebook, a pen, and a willingness to observe and listen are all you need. Over time, you’ll build something invaluable: a record of where water actually goes, written by the people who live with it.
Frank Sobieski’s binder sits on his workbench, next to a jar of pencils and an old radio tuned to the National Weather Service. He’s still adding to it, still knocking on doors, still tracing blue arrows across graph paper. “The river’s not done with us,” he says. “And I’m not done with the river.”
