New pipe under the streets, 2008 to 2010
In a release dated June 28, 2010, DEP described an "$11.5 million project – funded by DEP and managed by DDC – began in June 2008" in "Port Richmond, Staten Island." The work, by the release's account, installed "1,857 feet of storm sewers that range in size from 12-inches to five feet to improve drainage," added sanitary sewer mains of 16-, 12- and 10-inch diameter "to help avoid sewer backups," and replaced 3,250 feet of unlined cast iron water mains with ductile iron pipe. The release does not name the streets.
Three cautions come with that record. It is sixteen years old. It describes a project, not the whole neighborhood. And a new main in the street does not tell you what connects a particular house to it. The house lateral, often the original clay or cast-iron pipe, belongs to the owner; a camera scope from the cleanout to the street shows roots, offsets and bellies before they become a backup. Ask the seller, too, whether a backwater valve was ever installed.
The plant that carries the name
DEP's treatment-plant page lists Port Richmond as in operation since 1953, with a design capacity of 60 million gallons a day, a population served of 198,128, and a drainage area of 9,665 acres that DEP places in the island's north, with discharge to the Kill Van Kull. The page gives the plant's name, not its address. A May 19, 2010 release described a new throttling gate at the plant, a nearly $8 million investment the department said would cut combined sewer overflow discharges into the Kill Van Kull by up to 5.6 million gallons during heavy rainfall and an average of 30 million gallons a year. It does not say which streets drain through combined sewers, so treat any statement about a given block's sewer type as unverified.
Two-family houses and a prewar majority
In PLUTO, the city's tax-lot file, the official Port Richmond area has 6,900 residential units on 4,060 lots. Two-family houses account for 44.7 percent of units and one-family houses 31.3 percent; walk-ups are 11.9, three-family houses 2.4, condos 2.1 and elevator rentals 1.8. Built before 1940: 64.3 percent. From 1940 to 1979: 12.3 percent. From 1980 on: 23.3 percent. The median one- and two-family frontage is 31 feet.
Census figures for ZIP code tabulation area 10302, in five-year estimates for 2020-2024, run to about 45.3 percent single detached houses and 31.0 percent two-unit buildings (structure type), about 39.4 percent of homes from 1939 or before (year built), and about 55.1 percent owner occupancy (tenure).
For a two-family purchase, start with paper: the certificate of occupancy sets the legal unit count, and it should match the kitchens, meters and doorbells. Then the building. Prewar two-family frame houses typically share one foundation and one roof between two households, so a slow leak or a failing sill affects both units' rent and both units' repairs. Look at whether each apartment has its own heat and hot water, how the upper unit exits in a fire, whether the basement has been finished over old wiring, and whether an abandoned oil tank sits where a boiler used to be.
Four designated buildings
The New York Public Library Port Richmond Branch, at 75 Bennett Street, was designated on October 13, 1998. The Reformed Church on Staten Island, Sunday School Building and Cemetery, at 54 Port Richmond Avenue, followed on March 23, 2010. Public School 20 Annex, at 160 Heberton Avenue, dates from a March 22, 1988 designation. And the John De Groot House at 1674 Richmond Terrace, designated on June 28, 2005, lies within the city's Port Richmond neighborhood area according to the LPC dataset.
Flood zones on the Kill Van Kull side
FEMA's effective maps show A and AE zones along the shoreline of the city's Port Richmond area, plus Zone X, shaded for the 0.2-percent-annual-chance floodplain and unshaded beyond it. The preliminary maps add a VE zone. Neither kind of Zone X clears a lot, and the city's Sandy inundation layer reaches inside the official area. FEMA's Community Status Book shows the city's effective map as September 5, 2007, with no Community Rating System class. Look up the lot itself at the FEMA Map Service Center before relying on anything area-wide.
Zoning and getting around
Where a Port Richmond lot is zoned R1, R2, R3, R4A, R4-1, C3A, C1, C2 or C4, the Lower Density Growth Management Area in section 12-10 applies, and its added requirements deserve an architect's review before any addition; ZoLa shows the district. No station in the state's railway dataset falls inside the official area, so getting around starts on the road network.
What Local Laws 152 and 126 reach
The periodic gas-line checks required by Local Law 152 skip one- and two-family houses; three-family buildings in Community District 1 come up next in 2028. The basement-apartment statute, Local Law 126 of 2024, lists no Staten Island district, and as of September 2026 its rules remained proposals.
