WHAT IS CHARM?

CHARM is the Community Health And Resource Management mapping application.

It gives local officials, stakeholders, and citizens the power to map and analyze growth with real-time feedback. When used with the weTable, it forms a powerful planning tool for engaging the public and gathering their values about the community’s future. The mapping application is supported with a library of mapping data about urbanization, storm surges, conservation, public facilities, and coastal resources. The CHARM application can leverage local community knowledge for better long-term planning, and is an ideal tool for communities, watersheds, and environmental projects along the US Gulf Coast.

2.5 ACRE GRID

Users interact with the CHARM grid layer that summarizes 24 land-based characteristics and over 40 scenario- based attributes.

20+MAPPING LAYERS

CHARM looks up to mapping layers from federal, state, and regional agencies to inform impacts.

24 PAINTS

Users build scenarios using a paint of over two dozen development styles representing a range of land development patterns and uses.

10+ Assumptions

CHARM has the ability to modify certain assumptions about housing, the environment, and costs.

50+ CHARTS

Scenario outputs are updated live using over 50 charts and graphs to illustrate changes.

250+ INDICATORS

CHARM tracks over 200 scenario-based indicators about changes and impacts in a community, from habitats to resource use to critical facilities.

CHARM contains a wide variety data for your community

CHARM pulls together data from local, state, and federal sources to support meaningful dialogue about vision and values for the future. We overlap these data sets and let users apply hypothetical land development styles on them. See below for what CHARM can bring to the table.


City, county and state lines are used to know where

Critical Facilites.png

CRITICAL FACILITIES

Critical facilities include public services and utilities and show which might be vulnerable to natural hazards

Hurricane Track.png

HURRICANE TRACK

These tracks show over 120 years of tracking data for tropical cyclones

TRANSPORTATION

Roads are classified by local, state, and federal classification

The grid is the CHARM unit of analysis. It holds over 20 core attributes about land characteristics in the grid and over 100 indicators once a scenario is started

CHARM approximates how many people are in each grid square using census and parcel data

DEMOGRAPHICS

Pull in demographic data about age, income, and family size

SOVI.JPG

SOCIAL VULNERABILITY

These are demographic indicators that inform us about the capacity of populations to respond to disasters

Elevation is important, particularly with coastal hazards

BFE’s tell us about flood depth at certain points

Floodways are the most risk-prone section of rivers. Knowing where they are is important for planning

FIRM shows insurance zones based on 100 and 500 year risk zones

FLOOD DEPTH GRIDS

Depth grids show flood depths for 100 and 500 year events

Environmental and sensitive habitat data can show us where these areas are in our communities

PARCEL

Parcel data can help us understand land use activities happening in very specific locations

Land cover tells us the intensity of coverage in our communities, like impervious surface covery

Soils tells us about prime farmland areas, septic system drainage, and shrink-swell potential

Everyone lives in a watershed and are important for understanding how development impacts stormwater issues

Catchments are nested within larger watersheds and provide a finer scale for analysis

We use the National Weather Service storm surges models to inform our scenarios

Resiliency Workshops

FEMA is seeking ways to engage communities about risk awareness and to build hazard mitigation into local plans and policies. CHARM is helping these communities have that conversation. Since 2015, CHARM workshops have been held in twenty counties, attracting over 760 stakeholders representing dozens of communities, agencies, and organizations. More Texas counties are on deck for Resiliency Workshops in 2019. (more info)

CHARM Discovery workshops (LAN/HCFCD)

In November, 2018 a flood risk mapping workshop was held in Harris and Chambers counties, co-hosted by LAN Engineering and Harris County Flood Control District (HCFCD). CHARM was utilized as a platform for community stakeholders to identify and record where flooding has been observed in the past. This information from watershed stakeholders will then be used by engineers in a multiyear project to update local flood insurance rate maps.The mapping exercise focused on three watersheds- Cedar Bayou, Jackson Bayou, and Luce Bayou.

 
 

Community Resilience Index (CRI) with CHARM Pilot

In late 2018, a pilot CRI-CHARM workshop was held in Santa Rosa, FL in partnership with FL and LA Sea Grant programs. A standalone CRI workshop includes working with community leaders to examine how prepared they are for storms and storm recovery. By adding CHARM to the assessment, the community was able to identify weaknesses in their plans and community facilities. Due to the success of the pilot workshop, CRI-CHARM workshops could be coming in the near future.  

 
 

No Adverse Impact

ASFPM is working to help communities and professionals improve development practices through the framework of No Adverse Impact. As part of a day-long continuing education workshop ASFPM and TCWP have been working in partnership to bring a joint NAI-CHARM workshop to communities, including Biloxi, Mississippi in 2017 and New Smyrna Beach and St. Augustine, Florida in 2018. CHARM data was used to spin up new table-top scenario exercise specifically for these communities, providing a highly detailed, localized scenarios. Local stakeholders collaborated to think about growth, hazards, and community needs while utilizing FEMA’s Risk Map data and other local data sets. (more info)

 
 

Citizen Planner

Summer 2019, Citizen Planner will be hosting planning courses for local officials and focusing on hazards reduction. The training will utilize the CHARM platform as an interactive exercise for Citizen Planners to put their knowledge to use. This builds upon the success of the 2013 and 2017 Citizen Planner programs, a planning education program geared to local officials and staff about planning practices. Also this summer, the program will unveil an online virtual Citizen Planner program.(view website)

 
 
 

Highland Bayou Watershed Protection Plan

The Galveston Bay Estuary Program in partnership with the Texas Community Watershed Partners utilized CHARM in a watershed protection plan to estimate non-point source (NPS) loading in the Highland Bayou Watershed in Galveston County. The grid’s baseline data along with assumptions for pollution loading rates and other values allowed the project team to quickly update NPS loading in the watershed. (more info)
