Stormwater and Climate Resilience Factsheet

As the climate changes and precipitation becomes more intense, the impacts of stormwater runoff will become more frequent, severe, and widespread. Regulations to protect the environment require municipalities, developers, industry, and large commercial sites to take action to reduce stormwater entering waterways, but when storms are severe, the existing infrastructure may be inadequate. One way communities can address pollutants in runoff and improve resilience to extreme precipitation events is to upgrade stormwater management practices and infrastructure. But this takes dedicated funding

Stormwater and Climate Resilience – Spanish Version

A medida que el clima cambia y las precipitaciones se vuelven m·s intensas, los impactos de la escorrentÌa de aguas pluviales se volver·n m·s frecuentes, severos y generalizados. Las regulaciones para proteger el medio ambiente requieren que los municipios, los promotores, la industria y los grandes sitios comerciales tomen medidas para reducir las aguas pluviales que ingresan a las vÌas fluviales, pero cuando las tormentas son severas, la infraestructura existente puede ser inadecuada. Una forma en que las comunidades pueden abordar los contaminantes en la escorrentÌa y mejorar la resiliencia a los eventos extremos de precipitaciÛn es mejorar las pr·cticas de gestiÛn de aguas pluviales y la infraestructura. Pero esto requiere fondos dedicados. øQuÈ es una Autoridad de Aguas Pluviales

Road Flooding in Coastal Connecticut Final Report

A demonstration project was conducted to provide estimates of the frequency of flooding at two sites on RT 146 in Guilford and two sites in Branford. The project includes Sachem Head Road and Leetes Island Road in Guilford, and Indian Neck Avenue, Linden and Sybil Avenue, Limewood Avenue and Waverly Road in Brandord. The model required the analysis of observations, LIDAR surface elevations, GPS surveys and water level observations. The project provided current flooding frequency statistics, future flooding frequency statistics and the effectiveness of road elevation options on reducing the flooding frequency.

Jarvis Creek (Branford) Sea Level and Flooding Variability Final Report

The project demonstrates the effects of engineered tidal flow constrictions on the variability of the sea level in salt marshes and the frequency of flooding in upstream areas, focused on Jarvis Creek (Branford). The high water levels at Jarvis Creek Marsh, CT, have led to flooding on Leetes Island Road (RT 146) and at a field adjacent to the marsh. Exchange of water between Long Island Sound and the marsh complex is currently influenced by a tide gate and a berm at the southern end of marsh and a railway bridge that crosses the middle of the marsh.
