Land made from dredged fill
An archaeological study filed with the Landmarks Preservation Commission in 1987 (report 258) records that "between 1906 and 1909, ownership of Mill Island was transferred" to the Atlantic, Gulf & Pacific Company, which "bulkheaded and filled-in Mill Island, apparently using dredged fill material, creating 332 acres of upland." North of Mill Creek, between East 52nd Street and East 56th Street, filling had begun in 1905, with material "dredged from in front of the bulkhead and deposited behind it." A 1907 map showed two old barges inside the bulkhead line at East 57th Street, and the author thought it "possible that derelict vessels such as these were incorporated into the fill."
The company "planned to divide the land for industrial sites." Brooklyn Community Board 18 picks up the story: ports and dry docks arrived in the early 20th century, but "a lack of railroad connections hindered the area's further commercial growth," and residential development began in the 1950s. The Mill Island portion "saw its development in the 1960's into detached and semi-detached one and two-family homes." The City's tax-lot file (PLUTO), read as a rough estimate with an approximate boundary, agrees: the large majority of house lots on the peninsula carry a 1960s construction year.
Which Mill Basin?
The board says the area "has evolved into two (2) separate communities." This page is mainly about the peninsula, "bordered by Avenue U on the north and the Mill Basin inlet on its remaining sides," with Bergen Beach to the northeast, Flatlands to the northwest, Marine Park to the southwest and Floyd Bennett Field to the southeast.
Inspecting a 1960s house on filled ground
No public source we found documents settlement problems in Mill Basin, and this page does not claim any. Filled land changes the order of the inspection. Over fill, the structure comes first: the foundation walls and slab for stepped or widening cracks, floors checked for slope, door and window openings for racking, and the joints where a stoop, patio or garage slab meets the house.
Then the 1960s themselves. A house of that decade commonly still has its cast-iron drain lines and a 100-amp electrical service that was generous when installed. We weigh that panel against today's loads, such as central air or a car charger, and follow the drains where they are exposed. For two-family houses, our multi-family inspection reports each unit and its meters separately.
Private docks, bulkheads and Sandy's entry points
New York State's NY Rising Community Reconstruction Plan (PDF) for this part of Brooklyn (Part II, December 2014) notes that "Mill Island is home to numerous waterside homes that feature private docks, as well as semi-attached homes." It names Paerdegat Basin, "Mill Basin and East Mill Basin near the center of the Planning Area," and Shell Bank Creek as the "entry points for inundation during Superstorm Sandy." Across its five-neighborhood planning area it counts "2,890 residential buildings either partially or entirely in the high and extreme risk flood zones, the majority of which are one- and two-family residences in Mill Island and Bergen Beach."
The count is for five neighborhoods together, and "high" and "extreme" are the State's own planning labels from 2014, which do not set an insurance premium. A lender and an insurer go by the zone shown for the address at the FEMA Flood Map Service Center. The City's stormwater flood map, which models heavy rain, and the NYC Flood Hazard Mapper are worth opening too.
A timber or steel bulkhead and a dock are marine structures, and a home inspection does not extend to them. We describe what can be seen from the yard: leaning or bowed sections, soil lost behind the wall, sinkholes in the lawn near the water, corroded tie-rod ends. We recommend a marine contractor's evaluation before closing on any waterfront lot.
Driveways that ramp down
The State plan singles out residences along Avenue U "with driveways that ramp down into basements." On that layout we check the trench drain and where it discharges, the garage door sill, and whether a backwater valve protects the house sewer. The plan describes the area's sanitary and storm sewers as separate systems; that was not checked block by block with the Department of Environmental Protection. An archived DEP page lists Mill Basin in the Coney Island treatment plant's service area.
The industrial corner by Kings Plaza
The board notes that "the western part of the neighborhood contains local strip shopping, commercial and industrial use," and that in the late 1960s the corner of Flatbush Avenue and Avenue U became the Kings Plaza Shopping Center and Marina. The 1987 report places a National Lead Company works there, "certainly in operation by 1905," and its site map marks former oil tanks and the yards of a metals processor and of asphalt, coal or coke distributors. That is site history for the commercial waterfront only. We searched no environmental database and make no statement about residential lots.
The same corner is where the buses end. The State plan says "the Community has limited transit access" and lists four bus lines on Flatbush Avenue, the B41, B9, B2 and B46, "with Kings Plaza Shopping Center serving as a terminus," plus BM1 and BM4 express buses. That was 2014; confirm routes with the MTA. The closest subway stations it names, Flatbush Avenue–Brooklyn College (2 and 5 trains) and Kings Highway (B and Q), are outside the area.
Owner-occupancy, heating fuel and gas piping rules
ZIP Code Tabulation Area 11234 also covers Bergen Beach, Flatlands and most of Marine Park. There the 2020–2024 American Community Survey finds 68 percent of occupied homes owner-occupied (table B25003) and 89 percent heated by utility gas (table B25040). With that much gas in use, note that the Department of Buildings' Local Law 152 piping inspection cycle leaves out one- and two-family houses. Community District 18's covered buildings have 2029 as their next year.
