Kidwell’s gambit: One man’s gamble and the creation of Potomac Park

“Kidwell Meadows — riverfront views!,” contemporary advertisements might have read had John Kidwell’s bold real estate gambit succeeded. His attempt failed but the federal government’s long legal efforts to quash it led to the creation of Potomac Park.

In 1869 the City of Washington was struggling to remake itself after the chaotic years of the Civil War. The population of the District of Columbia had nearly doubled, surging from 75,000 to over 130,000. This population pressure encouraged developers to eye property outside the city itself. […] Soon other residential development jumped northward over Boundary Street to the hills of Mount Pleasant.

Georgetown druggist John L. Kidwell took another tack and looked in another direction, this time toward the Potomac River. Cities like Boston had been nibbling away at the rivers and bays on which they sat, creating more land and quickly developing it. Up to this point Washington hadn’t needed any more land. But opportunity presented itself as the Potomac River continued to silt up. Agriculture in Washington’s Montgomery County hinterland led to soil being washed into the river. Below the fall line at Georgetown the river widened, slowed, and the silt deposited. The land around Analostan Island slowly fluctuated, as did that on the opposite City of Washington shore. These deposits built up, slowly taking more and more solid form.

What Kidwell saw is very well illustrated by an Army Corps of Engineers map of 1871.

This map shows river soundings (depth) and what seems to be land which is labelled “cane brakes,” both to the south of Foggy Bottom and on the north side of Long Bridge. “Cane brakes” — or as usually labeled, canebrakes — are a kind of wild grass. Labelling the areas on the map as canebrakes implied land overgrown with thickets of grass. The Army engineers report from 1870 states that “[a]t low water the soil is entirely uncovered and has become so firm as to support the weight of a man.”[1] Kidwell could see this area from his house on the heights of Georgetown  at Prospect and Frederick (now 34th) Streets which had a commanding view over Georgetown, Washington, and the Potomac. (The house exists still and is now known as Halcyon House.)

The land survey resembled the cane brakes found on the 1871 Engineers map. A clearer comparison is visible in another map prepared for the court case stemming from Kidwell’s claim — the cane brakes from 21st Street eastward to 17th Street were not included in the survey.

In addition to “Kidwell Meadows,” the land south of Foggy Bottom, Kidwell laid claim to “Kidwell’s Land” — cane brakes on the north side of Long Bridge. …
