Inland Flooding Projects & Products

CIRCA focuses on understanding characteristics and trends of changing precipitation patterns and their influence on inland flooding in riverine communities using tested hydrologic models. In coastal areas where there are also rivers, rainfall contributes to flooding in coastal communities as well, packing a one-two punch.

Below is a brief summary description of our current Inland Flooding projects. Click the Learn More button to read the detailed project description, or use the left navigation.

Hartford – Green Infrastructure Specialist for a More Resilient and Sustainable Future

The City of Hartford received grant assistance from CIRCA to hire a Green Infrastructure Specialist for 12 months in support of the city's climate resiliency effort – the Climate Stewardship Initiative (CSI). Through the CSI, Hartford and its collaborators are making strides in five action areas (energy, land, transportation, waste, and water). Of these five areas, the city has the least expertise and the most need in the area of water – specifically in managing stormwater. The Green Infrastructure Specialist will help Hartford respond to threats of flooding while evaluating and advancing green infrastructure projects.

Municipal Resilience Planning Assistance for Sea Level Rise, Coastal Flooding, Wastewater Treatment Infrastructure, & Policy

The Municipal Resilience Planning Assistance for Sea Level Rise, Coastal Flooding, Wastewater Treatment Infrastructure, and Policy project provides information for wastewater system vulnerability assessments, combined river and coastal flooding for pilot sites, and policy options for priority resilience projects for towns in the Sandy-impacted counties.

Oxford – Planning for Flood Resilient and Fish-Friendly Road-Stream Crossings in the Southern Naugatuck Valley

The Town of Oxford, in partnership with the Town of Seymour, will assess its road-stream crossings to identify undersized structures (looking at current and future climate conditions). In both towns, road-stream crossings are highly vulnerable to floods as well as potential areas for conscious, conservation-oriented development. The towns will work with several partners to identify priority crossings, in order to target their future mitigation efforts. Oxford and Seymour will develop pre-replacement plans for structures most at-risk, and prioritized based on flood damage risk, crossing condition and maintenance need, and habitat restoration value. The towns plans to collaborate with CIRCA for the culvert vulnerability modeling portion of the project.

Through this project the towns will also develop a road-stream crossing inventory and a management plan. The resulting planning documents will be adopted as an annex to each town’s Natural Hazard Mitigation Plan facilitating implementation of the identified mitigation responses.

Real‐time Flood Prediction & Vulnerability Analysis of Connecticut’s Inland River Network

The Real‐time Flood Prediction and Vulnerability Analysis of Connecticut’s Inland River Network project provides a hydrology model for Connecticut’s rivers and applies this model to determine flood vulnerabilities in current and future climate scenarios.

RiverCOG Lower Connecticut River Valley Regional Council of Governments – Regional Long Term Recovery-Land Use Resiliency Plan

The RiverCOG is developing a Regional Long Term Recovery and Land Use Mitigation Plan for 17 towns based on real-time data and forecasts, mapping, and best management engineering practices for infrastructure (transportation, water, wastewater, utilities) as they relate to resilience in land use policies and climate adaptation. The Plan will create a template for towns to incorporate land use and infrastructure policies that will improve resiliency from natural hazard events and a strategy for long term recovery efforts after natural hazard events, specifically those that cause coastal and riparian inundation.

WestCOG – Regional CRS Program

In order to stem the high cost of flooding to home and business owners, the Federal Emergency Management Agency (FEMA) offers flood insurance in communities that comply with basic floodplain management standards through the National Flood Insurance Program. Communities may choose to enter into the National Flood Insurance Program’s Community Rating System (CRS) in order to reduce the cost of flood insurance premiums for their property owners. Communities participating in the CRS Program go above and beyond the minimum standards and, depending on their level of mitigation efforts, can garner insurance premium reductions from 5-45%.
