Flood zones street by street in Rittenhouse

The named streets in Rittenhouse, longest first, with how much of each street’s length inside Rittenhouse lies in FEMA’s high-risk flood zones (the Special Flood Hazard Area, zones A and V). Length is the part inside Rittenhouse; the main zone is the FEMA zone covering most of that length. A street can cross several zones, so the zone at one address can differ from the street’s main zone: check the address above for that. 21 shorter streets are not listed.

Streets: U.S. Census Bureau TIGERweb, Transportation (primary, secondary and local roads). Flood zones: FEMA National Flood Hazard Layer (NFHL), Flood Hazard Zones and FIRM Panels, retrieved November 7, 2026.

Flood zones in Rittenhouse

Share of Rittenhouse’s mapped area (about 1.358 km²) in each FEMA flood zone, from FEMA National Flood Hazard Layer (NFHL), Flood Hazard Zones and FIRM Panels. Effective date of the FIRM panel(s) covering it (42045C0150F, 4207570183G): January 17, 2007, November 18, 2009.

What the zones mean

Zone AE (and A, AH, AO)

High-risk: part of the Special Flood Hazard Area (SFHA), the area FEMA maps as having a 1-percent chance of flooding in any given year (the “100-year” or base flood). AE areas have a mapped base flood elevation.

Zone VE (and V)

High-risk coastal areas, also in the SFHA, where the base flood is expected to bring additional hazards from storm waves.

Zone X (shaded)

Moderate hazard: between the limits of the 1-percent and the 0.2-percent-annual-chance (“500-year”) flood.

Zone X (unshaded)

Minimal hazard: outside the SFHA and higher than the 0.2-percent-annual-chance flood elevation. Minimal is not zero: flood claims are filed from X zones too.

How much is flood insurance in Rittenhouse?

The typical National Flood Insurance Program policy on single-family homes in Rittenhouse costs $1,312 a year: the median of 12 policies that started between September 1, 2025 and August 31, 2026. Half of them cost between $1,205 and $1,399. That is the full amount paid for the year, the premium plus FEMA’s fees and surcharges, and every one of these policies is priced under Risk Rating 2.0. A quote for one building can be far from this: its elevation, foundation, age, coverage and deductible all change the price. Private flood insurance is not included.

Flood zone shares: the neighborhood polygon intersected with FEMA National Flood Hazard Layer (NFHL), Flood Hazard Zones and FIRM Panels, area computed in an equal-area projection; retrieved November 7, 2026. Claims: OpenFEMA NFIP Redacted Claims v3 records for Philadelphia County (county code 42101), dataset as of September 8, 2026, retrieved November 7, 2026. A 2010 Census block group is counted for a neighborhood when at least 25% of the block group lies inside the neighborhood, or at least 25% of the neighborhood lies inside the block group. Block groups used: 421010007003 (98.1% of the block group is inside Rittenhouse), 421010008041 (100.0% of the block group is inside Rittenhouse), 421010012012 (82.1% of the block group is inside Rittenhouse), 421010012014 (34.8% of the block group is inside Rittenhouse), 421010012013 (99.6% of the block group is inside Rittenhouse), 421010012023 (99.9% of the block group is inside Rittenhouse), 421010012022 (100.0% of the block group is inside Rittenhouse), 421010012024 (99.8% of the block group is inside Rittenhouse), 421010008031 (100.0% of the block group is inside Rittenhouse), 421010008033 (100.0% of the block group is inside Rittenhouse), 421010004011 (46.0% of the block group is inside Rittenhouse), 421010008032 (100.0% of the block group is inside Rittenhouse), 421010012021 (100.0% of the block group is inside Rittenhouse), 421010012025 (100.0% of the block group is inside Rittenhouse), 421010007002 (100.0% of the block group is inside Rittenhouse), 421010008043 (100.0% of the block group is inside Rittenhouse), 421010008034 (100.0% of the block group is inside Rittenhouse), 421010007001 (100.0% of the block group is inside Rittenhouse), 421010008042 (100.0% of the block group is inside Rittenhouse), 421010004022 (45.5% of the block group is inside Rittenhouse), 421010008011 (98.2% of the block group is inside Rittenhouse). Neighboring pages can share a block group, so their counts can overlap. Paid totals add building, contents and Increased Cost of Compliance payments and are not adjusted for inflation; a claim whose FEMA record shows a negative payment (an adjustment) counts as zero.
