Iselin is another section of Woodbridge Township, south of Colonia, with 20,088 people at the 2020 count. Oak Tree Road, the commercial strip, runs from the Garden State Parkway to Route 27, and the Metropark office park and rail station fill the southwest corner beside Edison. The Census median build year is 1959, give or take 3, same as Colonia's. Roof paperwork questions go to the township offices in Woodbridge, listed under Papers to ask for.
Between the Parkway and Route 27
Colonia lies to Iselin's north, Avenel to the northeast, Woodbridge to the southeast, Menlo Park Terrace to the south and Edison to the west. Oak Tree Road is the shopping strip, with the Garden State Parkway at one end and Route 27 at the other. Along Route 27 it continues into Edison for about a mile and a half in total. Newark is about 14 miles northeast and New Brunswick about 9 miles southwest.
The houses
Census Bureau ACS figures for 2020-2024 count about 6,738 homes in Iselin.
The 1950s account for 1,657 and the 1940s for 1,590, so 3,535 homes, about 52 percent, were built in 1959 or earlier. Another 906 date from the 1960s and 997 from the 1980s. Renters are a bigger share than in Colonia, living in 2,258 of the 6,512 occupied homes, about 35 percent. A renter with a roof problem calls the landlord or property manager first.

Where the South Branch crosses the west side
The South Branch of the Rahway River drains Iselin to the northeast. Woodbridge's floodplain description says the river crosses the township's western sections, inside the Colonia and Iselin sections, and that river flooding occurs there. It puts the highest ground in Colonia, Iselin and Fords at about 120 feet above mean sea level.
The township's 2014 recovery report, written after Sandy in October 2012, noted sporadic damage across five sections of the township: Iselin, Fords, Keasbey, Avenel and Colonia.
