This option appears in resilience plans from around the country.
| Option from plan | Hazards Sort descending | Assets | Region | Source Plan |
|---|---|---|---|---|
| Review the capacity of existing drainage structures to understand their ability to manage increased precipitation projections. Identify the likelihood and consequences of impacts to this infrastructure | Flooding – CoastalFlooding – GeneralFlooding – Rainfall-induced | Water Infrastructure – GeneralWater Infrastructure – Stormwater | Northwest | City of Seattle, WA: Preparing for a Changing Climate (p. 25–26) |
| Use local climate projection data to understand the risk of failing culverts in future years. Weigh the economic, societal and environmental costs against the benefits of installing new culverts. | Flooding – GeneralFlooding – Rainfall-induced | Transportation and Mobility | National | |
| Hire a stormwater program consultant to assess the jurisdiction's stormwater plan. | Flooding – GeneralFlooding – Rainfall-induced | Water Infrastructure – Stormwater | Southeast | Charleston, South Carolina - All Hazards Vulnerability & Risk Assessment (p. 189) |
| Study water system to identify manmade obstructions in water flow. Intersections, such as railway crossings and roadways, can create choke points in drainage | Flooding – General | Aquatic and Marine ResourcesNatural Areas and WildlifeWater Infrastructure – Stormwater | Southern Great Plains | Resilient Houston (p. 102 (pdf p. 104)) |
| Update the Intensity, Duration and Frequency (IDF) curves used by stormwater infrastructure designers to inform the sizing of new capital improvements based on latest precipitation data. | Flooding – General | Water Infrastructure – Stormwater | Northwest | City of Seattle, WA: Preparing for a Changing Climate (p. 26 (pdf p. 52)) |
| Review Level of Service (LOS) standards for stormwater across the region by doing a comparison of design standards. For example, low LOS standards upstream can negatively affect a neighboring jurisdiction | Flooding – GeneralFlooding – Rainfall-induced | Water Infrastructure – Stormwater | Southeast | Triangle Region, NC Regional Resilience Assessment (p. 180 (pdf p. 192)) |
| Undertake a comprehensive evaluation of stormwater improvements necessary to expand surface water storage, enhance water quality treatment and reduce stormwater discharges. | Water QualityDroughtFlooding – General | Water Infrastructure – Stormwater | Southeast | Southeast Florida Compact Regional Climate Action Plan - Energy and Fuel |
