Pluvial flood Hazard level: Very low ?

Pluvial floods, also known as surface water or urban floods, occur when intense rainfall exceeds the capacity of drainage systems to absorb or channel water away, causing water to accumulate on the ground surface. This hazard is particularly acute in urban areas with extensive impervious surfaces that prevent water infiltration. The severity depends on rainfall intensity, drainage infrastructure capacity, topography, and land use patterns, with low-lying areas and inadequate drainage systems most vulnerable.

In the area you have selected (Montserrado) urban flood hazard is classified as very low based on modeled flood information currently available to this tool. This means that there is less than 0.1% chance per year that potentially damaging and life-threatening urban floods occur (less than 1% chance in the coming 10 years). Therefore, based on this information, flood hazard does not need to be explicitly considered for your project. Although the hazard is considered to be very low or non-existent in the project location based on the information available in ThinkHazard!, additional information may show some level of hazard. If local or additional information sources suggest that there is flood hazard, seek expert guidance on additional recommended actions. It is recommended that local flood regulations and conditions possibly leading to highly localized water nuisance problems are considered. In particular, it is recommended to check the condition of and possible flaws in local water management systems, e.g. poorly dimensioned or maintained sewerage or drainage channels. Always consider taking no-regret measures.

Climate change impacts: Medium confidence of little change in amount or intensity of precipitation. The present hazard level may remain similar in the long-term when considering climate change only. However, changes to environment and land-use also influence how localized river flood hazard evolves into the future and alter future hazard level.
