Extreme Precipitation and Riverine Flood Risk Analysis

Factsheet on understanding and quantifying the flood impacts and damages is of great importance in flood risk evaluation and management, especially for coastal areas that might be affected by both high streamflow and surge. Meanwhile, the changing climate and land use are expected to increase thelikelihood and intensity of flood damages, due to the exacerbated effect of rainfall,storm surge and sea level rise.

Floodplain Building Elevation Standards for Critical Facilities and Activities, 2022

Flood protection elevations are critical safety factors for construction in the flood plain as well as a regulatory compliance step in relevant construction. Determining the appropriate flood protection height requirement for an infrastructure project can be complicated. Factors determining the applicable standards can vary depending upon location, funding source, construction type and critical/non-critical designation. Learn more with this white paper.

Floodplain Building Elevation Standards, 2018

This paper describes the following actions within existing municipal authority that will help Connecticut shoreline communities accommodate the Long Island Sound sea level rise projected for 2050, assure compliance with the elevation requirements of the Connecticut State Building Code, and enhance community resilience to flood event.

Height Restrictions on Elevated Buildings, 2018

This paper describes two approaches; 1) allow additional height above the surrounding grade or 2) allow additional height above a specified floodwater elevation provides the text of the floodplain height ordinances in eight communities that make such accommodations. Shoreline communities interested in enhancing coastal resilience should consider whether similar ordinances are appropriate for their situation. Learn more with this white paper.

Oceanfront State Coastal Management Programs, 2018

This white paper surveys the coastal management programs in the twenty- three oceanfront states. Individual state summaries describe the key features of the coastal management programs in each of the oceanfront states, while more details analyses address the genesis of the state programs, the exercise of coastal management jurisdictions and how state statues and regulations address sea level rise.

Sea Level Rise in Connecticut Final Report

In the this report we summarize the NOAA CPO-1 sea level rise projections of the potential trends in global mean sea level and their underlying rationale. We then describe the expected differences between global mean sea level and values in Long Island Sound at the shores of Connecticut. In Section 4 we present recent observation of sea level in Long Island Sound and evaluate whether changes have taken place. Since the NOAA CPO-1 projections
were developed there have been considerable advances in the science of climate change and sea level rise so in Section 5 we summarize recent projections and their relationship to the earlier work. We conclude in Section 6 with recommendations for sea level trends and their uncertainty bounds for use in planning and provide recommendations for their use and review.
