Seaside Park Neighborhoods: North End, South End, and No Invented Names
Seaside Park is a tiny borough -- 0.81 square miles total, 0.66 square miles of land and 0.16 square miles of water -- sitting on the Barnegat Peninsula between Barnegat Bay and the Atlantic Ocean. This page will not invent a list of named neighborhoods to make a town this size sound bigger than it is. No confirmed set of named neighborhoods, subdivisions, or wards inside Seaside Park turned up in this research pass, so none appear here. What is real and confirmable is a much simpler geographic split: the borough's north end, closest to the Seaside Heights border, and its south end, closest to the gateway of Island Beach State Park. That north-south position, not a named-neighborhood system, is what actually organizes this town.
Why This Guide Describes Zones, Not Named Neighborhoods
Seaside Park is this site's twentieth New Jersey market, and the second of the Central Jersey Shore stretch, built immediately after and adjacent to Seaside Heights. It shares that neighbor's barrier-peninsula geography but not its identity -- Wikipedia itself frames Seaside Park as "The Family Resort," a deliberate contrast to Seaside Heights' commercial-amusement, nightlife-driven reputation. At 0.81 square miles, Seaside Park is also simply too small to have generated a documented set of named residential neighborhoods the way a sprawling suburban town would.
That is not a research gap to apologize for -- it is a fact about the borough's scale. A town with a 2020 census population of just 1,436, down 9.1% from 1,579 in 2010, and down further still from 2,263 in the 2000 census, does not need, and does not have, a neighborhood map. What buyers and renters actually navigate here is position along a narrow strip of land: how close a property sits to the Seaside Heights border at the north end, versus how close it sits to Island Beach State Park at the south end.
The Original Borough: 14th Avenue to North Avenue
Seaside Park does have one piece of real, confirmed internal growth history worth understanding, even though it is not a named-neighborhood story. The borough was incorporated as independent on March 3, 1898, when New Jersey Senate President Foster M. Voorhees signed the incorporation bill carving it out of portions of Berkeley Township. That original 1898 borough ran only "from 14th Avenue to North Avenue" -- about half its present size. The additional land, known as the Berkeley Tract, was annexed around May 12, 1900, roughly doubling the borough to something close to its current footprint.
In 1914 the name itself changed from two words to one -- "Seaside Park" -- when a newly appointed municipal clerk simply wrote it that way in the council minutes. There is no elaborate name-origin story beyond that; the town was named plainly for its Atlantic Ocean location. None of this amounts to a set of named neighborhoods today, but it does mean the borough's footprint was assembled in two stages rather than laid out all at once, which is worth knowing even though no documented distinction in character between the original 14th-to-North tract and the annexed Berkeley Tract has been confirmed.
The North End: Closest to the Seaside Heights Border
Seaside Park borders Seaside Heights immediately to the north, and the two towns are frequently confused by outsiders because they share a name, sit on the same barrier peninsula, and once shared a stretch of connected boardwalk. Property near that northern border sits closest to Seaside Heights' Casino Pier and its 2-mile boardwalk, which means a short walk or drive can put a Seaside Park owner within reach of that busier neighbor's nightlife and amusement scene without living inside it.
This research did not confirm any named designation for that northern stretch of Seaside Park, nor any documented price differential between north-end and south-end property here. What can be said honestly is structural: in a borough only 0.66 square miles of land, the north end is, by definition, the part of town positioned nearest a genuinely different, busier neighbor.
The South End: Gateway to Island Beach State Park
Seaside Park's other real organizing feature is its position at the southern gateway to Island Beach State Park, one of the last undeveloped barrier-island stretches on the entire Jersey Shore. Route 35, the peninsula's main paved road, runs the length of Seaside Park before dead-ending into the state park just south of the borough. No single sourced page stated an exact shared-border distance between Seaside Park and Island Beach State Park, so this is presented as general, well-known geographic context rather than a precise boundary figure.
That proximity is nonetheless a real and distinguishing feature of the borough's south end: property there sits closest to an undeveloped natural stretch of coastline rather than to another town's commercial district. As with the north end, no confirmed named neighborhood exists for this part of Seaside Park -- it is a zone defined by what sits just beyond it, not by a documented name of its own.
Seaside Park vs. Seaside Heights: The Family Resort Contrast
Seaside Park's own identity is genuinely distinct from its immediate neighbor. Wikipedia's own framing describes Seaside Park as "The Family Resort," explicitly contrasted with Seaside Heights, where commercial amusement attractions developed instead. That contrast matters for anyone comparing the two towns: Seaside Heights built its identity around Casino Pier, a 2-mile boardwalk, and reality-television-era nightlife, while Seaside Park's own documented history and character lean quieter and more residential.
The two towns do share one somber chapter worth stating plainly rather than blurring: the September 12, 2013 ten-alarm boardwalk fire actually originated on Seaside Park's own end of the boardwalk, beneath a building housing Kohr's Frozen Custard and Biscayne Candies, in electrical wiring compromised by Hurricane Sandy floodwaters, before spreading north into Seaside Heights. It destroyed the Funtown Pier amusement park and more than 50 businesses; cleanup and demolition costs were reported at $4.7 million, with no single combined property-damage total confirmed beyond that figure. The boardwalk reopened for summer 2014, and Funtown Pier's planned rebuild was scrapped in July 2016 due to planning-board height restrictions. Seaside Park was the fire's true origin point, not merely a town that was also affected by it.
What This Page Does Not Have
No list of named neighborhoods, no subdivision map, and no north-end-versus-south-end price comparison appears here, because none was confirmed during this research pass, and inventing one for a 0.81-square-mile borough would do a buyer more harm than an honestly disclosed gap. What this page can responsibly offer is the real structure underneath: a narrow barrier-peninsula town bordering Berkeley Township and Seaside Heights to the north, sitting at the southern gateway to Island Beach State Park, assembled in two historical stages -- the original 1898 borough and the annexed Berkeley Tract of 1900.

Voorhees signed the incorporation bill carving Seaside Park from portions of Berkeley Township, with the original borough running only "from 14th Avenue to North Avenue" (about half its present size) before the Berkeley Tract was annexed around May 12, 1900; the name changing from two words to one in 1914 when a newly appointed municipal clerk wrote it that way in council minutes; Wikipedia's own framing of Seaside Park as "The Family Resort," explicitly contrasted with Seaside Heights, where commercial amusement attractions developed instead; Wikipedia's listing of Berkeley Township and Seaside Heights as Seaside Park's bordering municipalities, and the borough's position at the southern gateway to Island Beach State Park, presented as general geographic context since no single sourced page stated an exact shared-border distance; the September 12, 2013 ten-alarm fire that originated beneath a building housing Kohr's Frozen Custard and Biscayne Candies on Seaside Park's own end of the boardwalk, caused by Hurricane-Sandy-compromised electrical wiring, destroying the Funtown Pier amusement park and more than 50 businesses, with reported cleanup and demolition costs of $4.7 million and no larger combined property-damage total confirmed, boardwalk reopening for summer 2014, and Funtown Pier's rebuild scrapped in July 2016 over planning-board height restrictions; the June 9, 1955 "Freeman's Fire," which affected both Seaside Park and Seaside Heights and is not claimed here as exclusive to either town; the March 8, 1962 Ash Wednesday nor'easter, which destroyed a large section of the borough's boardwalk; the September 17, 2016 pipe bomb planted by Ahmad Khan Rahimi near the Seaside Semper Five Marine Corps Charity 5K, which detonated after the race's start had been delayed, resulting in no injuries, as part of a broader bombing spree that also struck Chelsea, Manhattan and involved devices found in Elizabeth, New Jersey, with Rahimi convicted on all eight federal counts on October 16, 2017 and sentenced to life -- a fully resolved matter, stated here factually and without invented casualty or motive detail; a 2020 census population of 1,436, down 9.1% from 1,579 in 2010, itself down from 2,263 in 2000; and the October 23, 1914 completion of the Toms River Bridge, which combined with new boardwalk and pier construction in 1915 to help drive a 219% population increase between the 1910 and 1920 censuses. No confirmed list of named neighborhoods, subdivisions, or wards within Seaside Park, no north-end-versus-south-end price differential, no current median home price or property tax rate, and no precise Island Beach State Park shared-border distance were found in this research pass, and none is invented here. New Jersey has its own state sales tax and its own property-tax structure, genuinely different from a no-sales-tax state, and none of that is assumed to carry over from any other market on this site.
