SUMMARY OF TOPIC 3 DISCUSSION

"WHAT WE HEARD" 

Top 3 Signals:

  • Small businesses are absorbing climate costs silently and unevenly: Flooding impacts are frequent, expensive, and very time-consuming, but largely undocumented and rarely captured in risk maps. In NYC there is 311, but small business owners are so busy in general (and more so when flooded) that they may not have time to report nor see the benefits.

  • It’s not so much about risk awareness as it is about ability to act: Small business owners often know their flood risk and maybe even what could reduce flooding…but they face structural barriers: lack of building control, lease limitations, cost uncertainty, and even fear of retaliation from the landlord. Existing programs like NYC Small Business Services and SBA disaster loans do make some help available but so much paperwork is required that many forego it altogether. 

  • There is no clear “owner” of the problem and so action stalls: Responsibility is fragmented across tenants, landlords, and the city. While NYC DEP invest in many types of solutions, from green to grey, they are long-term infrastructure and take many many years. In the meantime, there is no clear pathway to micro-mitigation leading to delays and repeated losses.

Emerging Themes:

  • Theme 1: Hidden and compounding costs of flooding

    • What we heard: Flooding costs include physical damage but also lost inventory, downtime, labor for cleanup, mold prevention, and lost customers. These costs accumulate over repeated events.  Because getting financial assistance is a lot of additional work, many small businesses feel they have to eat the costs, move on and get back to being open for business. 

“It’s not just the flood—it’s the days after. The cleanup, the lost business, the stress.”

  • Theme 2: Landlord / tenant misalignment is a central barrier

    • What we heard: Small business tenants often bear the risk but lack authority to make structural mitigation possible. So they are left to band-aid a solution or just recover as quickly as possible.  Some landlords may not prioritize mitigation (which can be expensive to really fix it) unless required through building codes (but focus there is newer, larger, expanding buildings) or incentivized through City or State resilient retrofit initiatives (but focus is homeowners, not small biz). 

“I can’t fix the building—and the person who can doesn’t feel the urgency I do.”

  • Theme 3: Fear and “lack of time” shapes decision-making

    • What we heard: Business owners hesitate to push landlords or report issues due to fear of rent increases, lease non-renewal, or eviction. Yes tenant protections exist under NYC commercial lease norms, but there is little awareness of any protections specifically tied to flooding and small businesses, nor is their appetite to “pick a fight” with the landlord and make things worse.

  • Theme 4: Insurance is inconsistent and not a clear fit

    • What we heard: Many small businesses either lack flood insurance or discover too late that policies don’t cover their specific type of flooding (e.g., sewer backup vs. coastal flooding, seepage). Programs like the National Flood Insurance Program don't seem to fit the realities for small commercial tenants, especially for non-coastal, stormwater flooding.  And even if there was, what is the ROI on that vs other potential actions like getting 4 sump pumps? One small business owner said her landlord HAD flood insurance but didn’t want to make the claim as it would raise their deductible by $50K.  So the tenant had to eat some costs that the landlord could have claimed.

  • Theme 5: Solutions exist but are hard to navigate

    • What we heard: There are viable mitigation strategies (barriers, backflow preventers, operational protocols), but no clear, trusted pathway for small businesses to assess, prioritize, and implement them. Existing city resources (e.g., NYC SBS guidance or NYC DEP green infrastructure programs) are not packaged in a way that is actionable at the storefront level.

“There is a lot of information out there—but no one is really connecting the dots for us.”

  • Theme 6: Strong appetite for collective and local approaches

    • What we heard: Positive response to ideas that “pool risk”, share resources, or operate at the neighborhood level, particularly through groups like Business Improvement Districts (BIDs). Models that combine financing (e.g., retrofit funds, CDFI-led programs like Spring Bank) with local coordination were seen as more viable than individual action alone.

Top 6 Tips for Small Business:

1) Barriers for stopping or diverting
  • Water-activated barriers (measure length) or flood gate

  • Focus on low openings: front and back doors, basement grate

  • Have extra to direct water to pumps

2) Address drain and sewer backup 
  • Install a backflow valves where needed with landlord approval 

  • In unused drains, install plugs or “balloons” 

3) Elevate critical inventory and equipment
  • Store inventory, appliances, and electronics at least 2 feet above floor level

  • Get EV batteries, delivery bikes up or can explode when turned on after wet

  • Get toxic chemicals up so they not spilling into flood water

4) Create a simple “3-hour storm plan”
  • MOVE HERE SPACES: where will you move expensive inventory

  • BARRIERS SETUP:  deploy barriers to “seal” or direct water to pumps

  • ELECTRIC UP: Electric cords unplugged or off ground

  • PUMP TEST: can you send water to green area vs street?

  • WHO BESIDES YOU: Does your team know what to do?

5) Pics and Vids
  • Take BEFORE, DURING, AFTER photos/videos (doors, drains, basement)

  • Track cleanup costs, damaged inventory, and lost business days

6) Submit

SUMMARY OF TOPIC 2 DISCUSSION

"WHAT WE HEARD" 

Top 3 Signals:

  • Climate is already compounding NYC’s affordability crisis across multiple systems: housing, energy, insurance, and water costs are all rising simultaneously, with climate acting as a multiplier across each. Over 50% of renters are already housing cost-burdened, and rising insurance (+18–32%) and utility costs are layering on top.

  • The biggest financial risk is NOT catastrophic events — it’s repeated, under-supported “medium” events. Smaller, frequent disasters often don’t trigger federal aid, yet create deeper long-term financial damage (credit score declines, debt, foreclosure risk).

  • Climate adaptation is creating a new inequality divide: “those who can afford to adapt” vs. those who cannot - The strongest predictor of taking protective action (insurance, mitigation, relocation) is ability to pay. This creates a structural split between “climate adaptation haves and have-nots,”

Emerging Themes:

  • Theme 1: Affordability is a system, not a single cost

    • What we heard: Climate impacts are embedded across housing, insurance, utilities, and infrastructure—not just rent. A “cheap” home that floods or overheats is not truly affordable.

  • Theme 2: The real cost of climate is post-disaster financial decline

    • What we heard: Flooding triggers cascading financial effects—credit damage, debt accumulation, foreclosure risk—that persist for years and worsen inequality.

      “Households with limited to no housing options can't really act on the risks that they're being exposed to.”

  • Theme 3: Insurance gaps are one of the biggest hidden risks

    • What we heard: Many households—especially outside official flood zones—are effectively self-insuring without realizing it, leaving them exposed to catastrophic out-of-pocket losses.

  • Theme 4: Information alone does not change outcomes

    • What we heard: Even with “gold standard” disclosures, many people don’t use or can’t act on information due to limited housing options or financial constraints.

  • Theme 5: NYC’s housing reality (renters + aging buildings) reshapes the problem

    • What we heard: With ~70% renters and many older, inefficient buildings in risk-prone areas, climate costs are mediated through landlords, policy, and building systems—not individual choice.

  • Theme 6: The core policy tension — build housing vs. avoid risk

    • What we heard: NYC must continue building affordable housing, often in vulnerable areas, but without sufficient infrastructure investment this locks in long-term risk and cost.

  • Theme 7: Must think multi-scale (property + neighborhood + regional)

    • What we heard: No single intervention works—success requires combining household mitigation, neighborhood infrastructure, and regional systems, alongside financing and policy alignment.

SUMMARY OF TOPIC 1 DISCUSSION

"WHAT WE HEARD" 

Top 3 Signals:

  • Speed matters more than perfection - Repeated urgency about 10-year timelines being too slow

  • Don't reinvent the wheel - Community knowledge exists; tap it rather than start from scratch

  • Equity concerns about resilience itself - Fear that flood protection could displace vulnerable communities

Emerging Themes:

  • Theme 1: Tap Into Existing Community Knowledge

    • What we heard: Communities are already doing resilience work—the city needs to recognize and support this rather than starting from scratch. As one attendee put it: "communities are engaged and already doing the work - take advantage of this vast wealth of knowledge."

    • Notable examples shared:

      • LA's 99 Neighborhood Councils with active Sustainability Committees

      • Sydney's community reference groups for neighborhood planning

      • Philadelphia's stormwater bumpouts and tree planting in row house neighborhoods

  • Theme 2: Stop Building in Flood Zones And Retrofit Those At Risk

    • What we heard: Clear, repeated message—new housing shouldn't be built in flood-prone areas. Questions raised about Red Hook's Brooklyn Marine Terminal and concerns about the Jewel Streets where "the Jamaica Bay runs under this neighborhood."

    • Key concern: Are we "prolonging the risk to housing tenants or other low income communities by going on with this project?"

  • Theme 3: Speed Up Implementation

    • What we heard: 10-year timelines for infrastructure (like sewers in Jewel Streets) don't match the urgency of the climate crisis. We need to expedite capital projects.

      "We do not have time to start from scratch!"

  • Theme 4: Resilience WITH Equity, Not Against It

    • What we heard: Concern that resilience projects like floodwalls could push flooding to lower-income communities. The city must address both climate risk AND displacement risk simultaneously.

      "How do we build climate resilience without displacing communities?"

  • Theme 5: Better Cross-Agency Coordination on Solutions

    • What we heard: At a city level, make DEP, Sanitation, NYCEM work together vs asking citizens to piece it all together. Multiple city agencies needed to provide climate adaptation solutions.  Yearly inspection and maintenance is critical (Green infrastructure, and NYCHA complexes have "missing parts"). 

  • Theme 6: Compensate & Resource Communities Properly

    • What we heard: It takes too long for non-profits to get paid for work city asked us to do.  Request to "pay community members to participate, to compensate for their time, just as consultants and experts are paid." Communities need resources, not just requests for input.
