The District sits on the north bank of the Potomac River, with the Anacostia River and Rock Creek as its two major tributaries. Rowhouse blocks, apartment buildings and park edges meet in a very small area.
The 2020 census counted 689,545 people in Washington, District of Columbia, across about 61 square miles of land. The city stands on the north bank of the Potomac River, where its lowest ground sits at sea level, and rises to 409 feet at Fort Reno Park. Rock Creek Park runs 9.3 miles through the city across 1,754 acres. Wikipedia counts 131 neighborhoods, and its photos include colorful rowhouses in Adams Morgan.
Dense rowhouses, apartment buildings and restaurants sit next to rivers, creeks and parkland. That mix keeps rodents fed, gives mosquitoes water, and lets cockroaches and bed bugs ride between units. The city takes the rodent side seriously: DC Health runs an integrated rodent control program that covers both public and private property.
