How to Choose Climate Resilience Planning Software

For thousands of local governments, the deadline behind any climate resilience planning software decision is the next hazard mitigation plan update, and that clock is already running. On October 29, 2026, FEMA's daily plan status data showed 558 local hazard mitigation plans, covering 4,695 jurisdictions, due to expire within a year, and 8,613 jurisdictions whose plans lapse within two, by the count in our hazard mitigation plan tracker. Each must be reviewed, revised and resubmitted within five years to stay eligible for mitigation project grants, and FEMA's own handbook advises allowing at least 18 months from start to approval.

The rules moved underneath that clock. FEMA's planning guide in force from April 19, 2023 required a plan's hazard probability to include the effects of future conditions, including climate change; the guide effective April 11, 2025 removed that clause, and probability can now rest on historical frequencies. Climate projections in a FEMA plan are a local choice: if you want them, your consultant or your software has to supply them.

Choose climate resilience planning software by the job it has to do. Use free federal and state tools for hazard data, a subscription tool for a quick first assessment, a consultant for a FEMA-approvable plan, a configurable platform to carry projects from plan to funding to delivery, and a custom build only when your governance fits no product.

We have a stake in the answer. Council Fire, a certified B Corp since 2010, was an implementation and stakeholder engagement partner for Phase I of the Annapolis Maritime Resilience Initiative, and CF Labs, our software studio, built Aptation with the Resilience Authority of Annapolis and Anne Arundel County, which the County calls the first multi-jurisdictional resilience authority in the nation. We also write scopes for the consultant route, such as our guide to an RFP for a hazard mitigation plan update. This guide compares the five approaches and the tools that come up first in search, from FEMA's Hazus to ICLEI's Temperate, and where an option we do not sell fits better, we say so.

What job are you buying the software for?

Three different jobs hide behind one search. The first is a risk picture: hazard data, exposure and, if you choose, climate projections. The second is a plan document that FEMA reviews against its requirements every five years. The third is a delivery record that carries each action from the plan into a budget, a grant application and a public report in the years between.

Most of the tools on the first page are built around the first two jobs, while FEMA's requirements lean on the third. Under FEMA's 2025 policy guide, a plan must say how, when and by whom it will be tracked over its five-year cycle. Each update must give the status of every action in the previous plan, for each jurisdiction, and explain how the plan reached other planning mechanisms such as capital improvement plans.

That third job decides what the update costs. If nobody tracked the last plan's actions, the update starts by reconstructing them, because FEMA wants the status of every one. FEMA's guide says an update does not need to involve a full rewrite and should focus on what changed since the last plan, which is cheap only if someone recorded what changed.

So buy for the update. FEMA does not require any specific format for a plan, so no product's template is what gets a plan approved; the evidence behind each element does. Our guide to implementing a hazard mitigation plan between updates shows what that record looks like, and our free Climate Risk Lookup shows any county's FEMA risk rating and plan status from FEMA's daily data.

Who this is for: emergency managers, planners and resilience coordinators deciding what to buy before a plan update, and the grants and finance staff who will pay for it.

Which approach fits your situation?

Match the approach to your situation before you compare products. The table maps the five approaches open to a county, city, resilience authority or regional planning agency, who each one suits and how each gets over-bought.

Most jurisdictions combine rows. The free tools sit under everything, a consultant or a subscription produces the plan, and a platform or a well-kept spreadsheet holds the record between updates. The expensive mistakes are asking the second row to do the third row's job, and buying the fourth row before anyone agrees what the ranking should weigh.

Who this is for: anyone writing a software line into a budget or a grant this year. If your plan expires within two years, start with the third row: FEMA's handbook advises pursuing funding no later than the third year of the five-year approval period.

What do the tools on the first page actually do?

Search for this software today and the first page is product pages, state tools and toolkits: ICLEI's Temperate, Climate Resilience Consulting's RIA, CDP's Adaptation & Action Explorer, FEMA's Hazus, New York's MitigateNY, CHaMP and the New York State Department of Environmental Conservation's Climate Smart Resiliency Planning tool. None of those pages compares the approaches, which is why the table above starts from your situation. Below is what each says about itself, on its own pages or its makers', as of October 29, 2026. We have not ranked them: they do different jobs, and the right one depends on your row.

Free federal tools

FEMA Hazus. FEMA distributes Hazus as free GIS-based desktop software, with inventory data for every state and territory, to estimate damage and losses from natural hazards. Version 7.2, released June 3, 2026, runs inside Esri's ArcGIS Pro 3.4 to 3.6 on Windows, and flood analysis needs the Spatial Analyst extension. FEMA encourages governments to use Hazus for the risk assessment in a hazard mitigation plan. It suits a county with a GIS analyst and an ArcGIS Pro license.

FEMA National Risk Index. FEMA publishes ratings for 18 natural hazards for every county and census tract, currently version 1.20 from December 2025, with downloads in table and GIS formats. For a town without a GIS analyst, this is the place to start.

Toolkits. The U.S. Climate Resilience Toolkit organizes its guidance as the Steps to Resilience, and FEMA lists its 2025 Local Mitigation Planning Handbook as the guide that takes local planning teams through the planning process. Both are free to read, and both assume someone on staff has the time to follow them.

Who this is for: every jurisdiction, as the base layer. Before you pay for hazard data, check whether these tools already provide it; our climate risk assessment guides collect the sources.

Free regional and state tools

CHaMP. The Climate Hazard and Mitigation Planning tool was designed specifically to support the development of FEMA hazard mitigation plans, according to a factsheet from GLISA, which offers free technical assistance with it. It draws historical climate data from PRISM, projections from LOCA downscaled climate models and past events from NOAA's Storm Events database, and it writes customized narrative text a planner can paste into a plan. Version 1.0 is publicly available on the CHaMP site, where you can check its coverage for your state. Now that FEMA no longer requires climate change in hazard probability, a tool like this is one way to keep future conditions in a plan if your community wants them.

MitigateNY. New York's Division of Homeland Security and Emergency Services worked with the University at Albany's AVAIL lab to turn the state's hazard mitigation plan, once a 2,000-page document, into a nonproprietary, web-based planning platform. The division's hazard mitigation planning page links to its plan status for New York communities. Outside New York, ask your State Hazard Mitigation Officer what your state provides before you buy anything.

NYSDEC's Climate Smart Resiliency Planning tool. The Department of Environmental Conservation's Climate Smart Communities program released it in 2013 to help local planners assess how well their existing plans incorporate resiliency to climate hazards, with a companion spreadsheet available on request. It checks the plans you already have, which makes it a sensible first step for any New York municipality.

Who this is for: jurisdictions in the regions and states these tools cover, and anyone who wants future conditions in a FEMA plan without buying a subscription.

Subscription, GIS and nonprofit tools

ICLEI USA's Temperate. ICLEI USA describes Temperate as its climate adaptation tool, offered in partnership with Azavea through an annual license fee, for assessing climate hazards and adaptation priorities with temperature, precipitation and other climate data specific to a community. ICLEI says its local governments often use Temperate to develop climate vulnerability assessments. The page does not list the fee, so ask ICLEI USA for current access and terms.

Climate Resilience Consulting's RIA. The Resilience Intelligence Advantage launched on August 3, 2026 as a subscription platform that generates a grant-ready climate resilience plan from a ZIP code or city name in under 15 minutes. The plan covers a risk profile across flooding, extreme heat, wildfire, drought, severe storms and social vulnerability, an action plan drawn from more than 1,000 resilience actions, grant-ready project narratives and a dashboard exported as a PDF, built on FEMA's National Flood Hazard Layer, NOAA HeatRisk, USGS data and the CDC Social Vulnerability Index. At launch, early-adopter subscriptions started at $450 a year; on October 29, 2026, RIA's site said plans start at $1 per day through its Early Adopter Program, paid annually, and that it accepts government purchase orders. Neither the release nor the site claims the output is a FEMA-approvable hazard mitigation plan, so run the FEMA plan as its own job.

CDP's Adaptation & Action Explorer. CDP launched the Explorer on June 8, 2026, built with Google.org support, as an AI-powered platform drawing on disclosures from more than 1,000 governments in 80 countries, covering 16% of the world's population, plus hazard maps for eight hazards from Google Earth Engine. Its product page says the AI assistant draws on CDP and approved datasets and offers insights without prescriptive recommendations, and that the data refreshes after each annual disclosure cycle. A government that did not disclose to CDP in 2025, or did not disclose publicly, will not find its own data there. Its pages list no price.

Esri's ArcGIS Hazard Mitigation Planning solution. Searches for hazard mitigation plan update software also surface this one. Esri describes the solution, first released in March 2025, as a way to run geospatial hazard risk assessments and share mitigation planning information, with hazard risk maps for the public, and lists ArcGIS Online and ArcGIS Survey123 as requirements. It fits a county that already runs ArcGIS.

Who this is for: small and mid-size cities that need a first climate vulnerability assessment, a climate resilience plan for grant applications or peer examples quickly, and counties already working in ArcGIS. If you would rather commission the assessment, our RFP guide for a climate vulnerability assessment scopes it.

When does a consultant, a platform or a build make sense?

The last three rows of the table are about who does the work and who keeps the record afterward.

A consultant-led plan

FEMA's handbook is blunt about the role: "Consultants do not own the planning process! They facilitate it." Hire one when you lead a multi-jurisdictional plan, when the stakeholder process is large, or when nobody on staff can carry an 18-month project.

The same handbook treats a consultant's contract as complete when the plan reaches the FEMA status of Approvable Pending Adoption or Approved, so tie the final payment to that status. For scale, Anne Arundel County's fiscal 2022 subapplication to FEMA for a plan update totaled $97,222 in FEMA's grant data.

The over-buying risk is a shelf document. Require the action table, scores and map layers as data deliverables in editable formats, alongside the PDF, so the record has somewhere to live after the consultant leaves. Our hazard mitigation plan update RFP guide has sample scope language, including how to ask for future conditions now that FEMA no longer does.

Who this is for: counties and regional planning agencies leading a multi-jurisdictional plan, and any jurisdiction whose plan expires within about three years.

A configurable platform

A platform earns its cost between plan updates. Aptation, which CF Labs built with the Resilience Authority, is one example: it maps every project, scores each from 1 to 4 against the criteria and weights your community chose, sorts the portfolio into High, Mid and Low tiers by rank, and keeps each project's funding sources, fiscal-year budget and deadlines in one record, with AI drafting scores that staff confirm. Benefits are recorded as potential, targets show whether they are met, on track or behind pace, and results go out as printed reports, view-only links and a public portfolio; Resilient & Ready Anne Arundel, the Authority's public portfolio, runs on it. Projects come in from spreadsheets, uploaded plans and studies are read for candidate projects your team reviews, and data goes out as CSV.

Know its edges. Aptation is not a grant search engine: your team adds the programs it pursues. It works from the projects in your plan, so the risk assessment and the plan document still come from the free federal tools or a consultant. A platform ranks on the criteria you give it, so agree on them first; our guide to prioritizing climate resilience projects covers how.

Who this is for: counties, cities and resilience authorities running projects across departments, with funders and residents watching. If your list is short and has one owner, a spreadsheet and a GIS story map may be all you need; our guide to cloud platforms for spatial disaster data compares the mapping options.

A custom build

Build when your governance is unusual. A resilience authority financing projects across a city and county line, or a regional body with its own revenue, runs on rules no product ships with. CF Labs either sets Aptation up around your program or builds the tool it does not cover, such as climate screening for a capital plan or a tracker for a single program. Our guide to building or buying resilience planning tools sets out when each wins, and our custom software budget brief helps you price the build.

Who this is for: resilience authorities, regional bodies and larger counties whose governance, integrations or public reporting fit no product's defaults.

What should you check before you buy?

Five checks separate a good fit from a good demo. Run them on every option, ours included.

FEMA's plan requirements

If a FEMA-approvable plan is the goal, read the requirements before the brochures. They sit in 44 CFR 201.6 and FEMA's Local Mitigation Planning Policy Guide, effective April 11, 2025 for all plan approvals, and reviewers check each element, from the planning process (A) to adoption (F), with FEMA's Plan Review Tool. The guide says local staff may use that tool as a checklist, so ask every vendor or consultant to show which element each output supports. None of the product pages we reviewed claims FEMA approval of its output.

Decide your position on climate before you shop. With the climate change clause gone from FEMA's guide, future conditions are yours to require, in the scope or in the tool, though the guide lets states add requirements of their own under Element H, so check yours first. Standards such as ISO 14092:2026 for local climate adaptation can anchor that choice.

The update cycle

FEMA starts the five-year clock on the approval date in its letter, whatever the date of your council's adoption vote, and a plan that is only Approvable Pending Adoption does not yet meet the approved-plan requirement for assistance. FEMA's handbook advises budgeting at least six months for state and FEMA review and pursuing funding by the third year of the approval period, because funding can take up to 12 months to secure. In Maryland, 10 of the 20 approved local plans in FEMA's data expire within two years; our Maryland county risk profiles show the hazards behind them.

Our counts in this guide group the approved single- and multi-jurisdiction local plans in FEMA's plan status data by plan on October 29, 2026; FEMA notes the data is raw and subject to entry delays. Whatever you buy should produce the update's evidence from the first year: each action's status, owner and date, and how it reached the capital improvement plan.

Data export and ownership

Insist on getting everything out, on a schedule and in documented formats: actions and projects as CSV, map layers in a standard GIS format and editable plan files beside the PDF. If federal money pays, 2 CFR 200.315 lets you copyright work developed under the award, while the federal agency keeps a royalty-free, nonexclusive and irrevocable right to use it for federal purposes, and the federal government may obtain and use data produced under the award. Write source files, data, hosting, administrator accounts and the exit into the contract. Confirm, too, that you can answer a public records request without calling the vendor.

Accessibility

Anything the public sees has to be accessible, whoever hosts it. The Justice Department's ADA Title II rule applies WCAG 2.1 Level AA to web content and apps a state or local government provides directly or through contractual, licensing, or other arrangements, and an April 2026 interim final rule set compliance dates of April 26, 2027 for governments with 50,000 people or more and April 26, 2028 for smaller ones and special districts. Ask each vendor for conformance evidence for its public pages before you sign, and test the public dashboard or portfolio yourself with a keyboard and a screen reader.

Procurement thresholds

Federal money brings federal buying rules. FEMA's Information Bulletin 552 confirms that, effective October 1, 2025, the federal micro-purchase threshold rose from $10,000 to $15,000 and the simplified acquisition threshold from $250,000 to $350,000, for procurements under all open FEMA awards. Under 2 CFR 200.320, a micro-purchase can go without competitive quotes when the price is reasonable and documented, a simplified acquisition needs quotes from an adequate number of qualified sources, and formal procurement applies above the simplified threshold. A recipient can self-certify a micro-purchase threshold of up to $50,000 a year, and the bulletin notes that federal increases do not necessarily change state, tribal or local thresholds, so your own code may set a lower limit.

On federal money, and where your own rules allow, a $450 subscription or a fixed-price prototype under $15,000 can move as a micro-purchase, a plan update the size of Anne Arundel County's falls between the two thresholds, and a multi-year platform contract can cross into formal procurement. Grants end; licenses renew. GAO found that, as of March 2025, FEMA had reimbursed $62 million of about $2.5 billion allocated to 1,245 BRIC subgrants, and that FEMA awarded no subgrants from April 2025 to March 2026. Put any recurring license in a recurring budget line before you sign; our guides to funding resilience without federal grants and an RFP for FEMA mitigation grant support cover both sides of the money.

Who this is for: procurement, grants and finance staff, and the resilience lead who signs the scope.

How do you test the choice before you sign?

Put every shortlisted option to work on your own plan. Give each one the action table from your current hazard mitigation plan and ask it to do five things while you watch:

1. Show the status of every action from the last plan, by jurisdiction, the way FEMA's update element asks.
2. Name who tracks each action and when, and show how that record reaches the capital improvement plan.
3. Map its outputs to FEMA's Plan Review Tool, element by element.
4. Export everything, from actions and scores to map layers and documents, in documented formats and without a services contract.
5. Show accessibility evidence for anything the public will see, and the price in years two and three.

If a build is on the table, commission a short prototype on the same action table and judge it the same way. The option that makes your next update smaller is usually the right one, whatever it costs this year.

Agree on your criteria before the demonstrations. A platform can only rank projects on criteria someone has agreed, and a consultant can only prioritize actions against goals your board has set. Council Fire works with municipalities and government agencies on those decisions before any software is bought, and we would rather you buy nothing than buy the wrong row.

Who this is for: evaluation committees and resilience leads about to sit through demonstrations.
