Trenton will protect and promote access to its natural resources and open space, including natural ecosystems.
Initial work defining, prioritizing and addressing these hazards was completed within Trenton’s Natural Hazard Mitigation Plan (2008). The goal of that plan, carried over below, was to “Ensure that Trenton, its citizens, assets and operations, have the best possible protection from the future effects of natural hazards”. The City identified flooding and high wind events as the highest risks to the City. One factor that the previous study did not evaluate is the impacts of sea level rise, which could affect the northerly reach of tidal impacts on the Delaware River, aggravating the effects of flooding in the City.
Trenton is located at the confluence of the Assunpink Creek and the Delaware River. The combination of these geographic features reduces the ability for stormwater to exit the drainage basin and leads to “stacking” of floodwaters within the City Limits. Moreover, nearly 20% of Trenton is within the 100 and/or 500-year floodplain. Approximately 50% of the Transportation/Communications and Utility infrastructure areas of the city are affected by floodplain issues. To a large degree, these areas are located along the low-lying natural waterways of the City. This transportation, utility and communication infrastructure is essential to Trenton’s ability to prevent widespread damage and recover from large-scale storm events.
The Hazard Mitigation Plan identifies initiatives including increased awareness, risk assessments, and cost-effective projects and actions as key components to Trenton’s ability to recover from natural hazard events. It is anticipated that City-wide educational efforts and projects within the floodplain areas of the City can be prioritized to increase Climate Resiliency. Specifically, additional study of the impact of Sea-Level rise to compound impacts to the City during flooding and high wind events should be conducted.
The City must develop resiliency initiatives that protect the City and its residents during and after severe weather events.
