# What’s happening
– Mayor’s Office told New Yorkers to check coastal evacuation zones and evacuation centers; Mayor’s Office; effective immediately.
– City Planning discussions include floodgates designed to raise protection to Elevation 10 feet; Department of City Planning; design underway through August.
– Department of Environmental Protection lists $2.5 billion for Southeast Queens stormwater upgrades in the current capital plan; DEP; funded in current plan.

# Why it matters
– Residents in coastal evacuation zones and neighborhoods prone to sewer or street flooding are directly affected.
– Planned defenses and drainage upgrades aim to reduce street flooding, sewer backups, and storm-surge damage during storms.

# Key details
– Mayor’s Office hurricane guidance video published August 29, 2026; advises checking zones and City-run evacuation centers at finder.nyc.gov/hurricane.
– Floodgates proposed to increase protection to Elevation 10 feet, accounting for 30 inches of sea level rise and 6 inches of freeboard.
– DEP lists $2.5 billion for Southeast Queens stormwater investments in the current capital plan.
– DEP five-year capital plan for water and sewer totals about $20.2 billion; projects include Gowanus CSO retention and borough-specific sewer upgrades.
– Developers and planners are considering green infrastructure measures like bioswales and underground stormwater storage to limit runoff increases.
– Hazard Mitigation Grant Program (HMGP) funding requires feasibility, environmental acceptability, and a benefit-cost ratio of 1.0 or greater.

**NYC Mayor’s Office**
– Role or jurisdiction: Citywide executive office that issues public safety guidance during storms.
– Action taken or responsibility: Urged residents to know coastal evacuation zones and to use the city’s evacuation-center finder.
– Relevant numbers or dates: Public guidance video published August 29, 2026.

New York City’s mayoral briefing opened with a direct public message: know your coastal evacuation zone, pack a go-bag, and sign up for emergency alerts. The Mayor’s Office said the city maps six evacuation zones and that Zone 1 is most vulnerable to storm surge. Source: https://youtu.be/A73fKTE53fQ
**Department of City Planning**
– Role or jurisdiction: City agency advising on land use and waterfront planning.
– Action taken or responsibility: Presented flood-protection concepts and timelines at commission review sessions.
– Relevant numbers or dates: Floodgate designs propose Elevation 10 feet protection; design and review activity noted through spring and into August in meeting records.

City Planning Commission sessions reviewed coastal resilience elements for waterfront projects, including discussions of floodgates and street-raising in vulnerable neighborhoods. Planners said floodgates under review would raise protection to about Elevation 10 feet and aim to address a 10% annual-chance coastal storm while accounting for projected sea level rise and freeboard.

Planners discussed schedule items for these projects, including coordination of design review, public review of environmental assessments, and interaction with FEMA’s Hazard Mitigation Grant Program (HMGP). The HMGP process was described as requiring feasibility, constructability, environmental acceptability, and a benefit‑cost ratio of at least 1.0. Source: https://youtu.be/76S2pGbUeQA?t=1624
**New York City Department of Environmental Protection (DEP)**
– Role or jurisdiction: City agency responsible for water, sewer, and stormwater infrastructure.
– Action taken or responsibility: Managing capital investments for stormwater management, sewer upgrades, and groundwater monitoring.
– Relevant numbers or dates: DEP cited $2.5 billion for Southeast Queens stormwater projects and a roughly $20.2 billion five‑year capital plan for water and sewer.

DEP testimony at Council hearings and budget briefings listed major capital investments addressing stormwater and sewer capacity, including multi‑hundred‑million dollar projects in Bushwick, East New York, and Dyker Heights, and a $621 million Gowanus combined-sewer overflow (CSO) retention facility. DEP staff also described programs to map groundwater and expand stormwater management in hard-hit neighborhoods.

Planning and development hearings indicated that private projects in the coastal zone may use green infrastructure measures — including bioswales and street trees — and underground stormwater storage tanks to comply with the city’s uniform stormwater rule and to avoid increasing local flooding. Those project-level measures are being discussed alongside larger publicly funded works. Source: https://youtu.be/Y2JaVn4PjQw?t=1939 https://youtu.be/xUAWmrNVw-c?t=2969
Multiple agency and planning sessions stressed that resilient waterfront projects built as public parkland or engineered barriers have reduced flood risk for nearby properties, citing recent Manhattan waterfront projects as examples where nearby buildings are no longer considered at the same level of flood risk. These comments came during Department of City Planning discussions. Source: https://youtu.be/ecpR7tQHW98?t=7332
City officials told planners and Council members that maintaining funding is critical. DEP testified that recurring revenue shortfalls would force cuts to capital investment, and that preserving the capital program is necessary to continue major stormwater and sewer projects. Those budget hearings outlined how cuts could affect specific flood-protection projects. Source: https://youtu.be/QYkDWGSs1SA?t=2577
For immediate public action, the Mayor’s Office directed residents to check their coastal evacuation zone and to find City-run evacuation centers via the City’s hurricane center finder. The office also advised signing up for emergency alerts and preparing a go-bag with medications and documents. Source: https://youtu.be/A73fKTE53fQ
