Prince's Bay & Annadale Flood Exposure · NYC DEP Separate Storm Sewer Area
Prince's Bay & Annadale, Staten Island - MS4 Area
Properties here drain through separate storm sewers: rain runs in its own pipes straight to Lemon Creek, apart from the sewage. When a storm drops rain faster than the catch basins can take it in, the water collects on streets and low lots instead. Here’s what that looks like for Prince's Bay & Annadale, Staten Island specifically.
7,858 properties in Prince's Bay & Annadale, Staten Island drain through separate storm sewers to Lemon Creek, which opens onto Raritan Bay. Flood Form rates 19% of them Moderate or High for stormwater, 4% for sewer backup, 9% for groundwater, and 3% for coastal flooding. 92% of lots have yard area that legally qualifies for on-site infiltration. Ground elevation varies widely here: the land drops from about 130 ft to 33 ft, sloping down toward the south. Rain that falls uphill runs down the streets toward the low end, so properties there take on water from the blocks above as well as their own, and are the first to see ponding and sewer backups when the pipes fill. Properties higher up shed water downhill and pond less, so where a lot sits on the slope matters more here than any average for the area. The median building dates to 1986. 10% of parcels sit over a historic stream or pond. Their runoff reaches the water through 17 NYC DEP storm sewer outfalls.

Common solutions for Prince's Bay & Annadale properties
The measures that most often suit conditions here. An individual Flood Form picks the exact set for one lot. See all flood prevention solutions.
Downspout Diversion
Redirect roof downspouts away from the sewer system toward permeable yard areas, planters, or a rain barrel.
Complexity: Low · 1–4 weeks
Modular Drywell System
An NDS Flo-Well modular drywell system lets water soak into the ground on-site.
Complexity: Moderate · 1–3 weeks
Rain Garden
A shallow planted depression that collects runoff from roofs and paved areas and lets it soak into the ground over a day or two.
Complexity: Low · 1–3 weeks
Detention System
A detention cistern or underground storage tank temporarily holds stormwater runoff and releases it slowly after storm peaks subside.
Complexity: High · 3–6 months
Area Drain
A yard area drain — a surface inlet at the lowest point in the yard — provides a direct outlet for stormwater that pools on the site.
Complexity: Low · 1–4 weeks
Increase Permeable Area
On-site interventions include permeable paving for driveways and walkways, removing concrete from yard areas, and adding planted beds — reducing impervious coverage that limits the neighborhood's collective capacity to absorb rain.
Complexity: Low · Ongoing

Questions about flooding in Prince's Bay & Annadale (Lemon Creek)
What does it mean that Prince's Bay & Annadale has separate storm sewers?
This part of Prince's Bay & Annadale, Staten Island is served by a separate storm sewer system, which NYC DEP calls an MS4. Catch basins and roof drains carry rain in their own pipes straight to Lemon Creek, which opens onto Raritan Bay, while wastewater flows in another pipe to a treatment plant. Because rain doesn't share a pipe with sewage here, a storm is less likely to push sewage back into basements than in combined-sewer neighborhoods, though a blocked or undersized house sewer line can still back up. Flooding here mostly comes from runoff the storm drains can't take in fast enough, and from groundwater and tides.
How exposed to flooding is Prince's Bay & Annadale (Lemon Creek)?
The most widespread exposure in Prince's Bay & Annadale is stormwater: Flood Form rates 19% of properties Moderate or High for it. The share is 4% for sewer backup, 9% for groundwater and 3% for coastal flooding. These figures describe the whole area, and exposure varies lot by lot within it.
Can properties in Prince's Bay & Annadale (Lemon Creek) manage stormwater on site?
92% of lots in Prince's Bay & Annadale have yard area that legally qualifies for on-site infiltration, such as a drywell or rain garden. A lot without that room can still hold runoff with a detention tank or a blue roof.
Why does runoff from Prince's Bay & Annadale matter for Lemon Creek?
Storm sewers here discharge runoff without treatment, so what washes off streets, roofs and yards ends up in Lemon Creek. Holding roof runoff on site with a rain garden, drywell, or detention tank cuts flooding on the property and what reaches the water.
