The purpose of this project is to FIGURE 1 help municipal officials and public works staff prioritize bridge and culvert upgrades in their towns. This report also provides information on how to make road-stream upgrades more resilient to current and projected precipitation conditions. Roads, bridges, and culverts in the Deerfield River Watershed are particularly vulnerable to flooding, as Tropical Storm Irene demonstrated in 2011. Events like Tropical Storm Irene are projected to become more frequent due to climate change. Upgrading and replacing culverts and bridges with structures that can withstand higher flows will save money over the long term, help protect critical infrastructure, and improve aquatic habitat in the watershed. The information in this report comes from a pilot project completed by the Massachusetts Department of Transportation (MassDOT) and the University of Massachusetts, Amherst (UMass). The intent of the project was to develop a methodology for determining the vulnerability of inland transportation networks to climate change, and specifically, to extreme precipitation events. The analysis identified and mapped road-stream Figure 1: The MassDOT project considered five factors crossings in each town within the Deerfield River Watershed. Over 900 when determining overall vulnerability of a crossing: crossings were evaluated through field work completed by Trout structural condition; geomorphic condition; hydraulic Unlimited. The analysis looked at five factors (Figure 1) when considering condition; disruption of emergency response; and the vulnerability of a crossing. An interactive online tool, SHEDS: Stream potential to improve aquatic organism passage. Image Crossing Explorer,1 was created showing the results of the evaluations, and source: UMass Amherst is described in more detail on pages 14 to 19. 1 http://sce.ecosheds.org/ High Risk Stream Crossings in Hawley, MA September 2018 1 Definitions For the purpose of this report, the crossings identified as having a high Overall Risk of Failure in the SHEDS tool have been included. These crossings are vulnerable due to one or more of the following factors:  Structural Condition – Risk of failure is based on the structural condition of the crossing. Data comes from MassDOT bridge inspection reports or culvert condition assessments conducted in the field by Trout Unlimited or UMass Amherst students.  Hydraulic Risk – Risk of failure is based on how much water a crossing can handle before collapsing, overtopping, or washing out. Hydraulic Risk was determined through models of current and future stream flows for different storm events.  Geomorphic Risk – Risk of failure is based on the likelihood of sediment plugging, woody debris, and channel adjustment at the crossing structure. A geomorphic scoring index was used to assess each crossing for structural alignment, structure width versus stream channel width, stream power versus substrate type, evidence of deposition or erosion, condition of the structure’s footings, existence of a scour pool, and existing blockage. Massachusetts Stream Crossing Standards The Massachusetts Stream Crossing Standards2 apply to all new permanent crossings, and to replacement crossings to the extent feasible. The standards were created to protect and improve stream health by designing culverts and bridges to accommodate fish and wildlife passage. Common problems for fish and wildlife passage at crossings (Figure 2) also tend to place these crossings at a higher risk for failure during a flood event. While the standards focus on improving river and stream ecosystems, designing crossings with rivers in mind also makes those structures more resilient to flooding, allowing for larger volumes of water and debris to safely pass through. The Stream Crossing Standards establish minimum criteria necessary for fish and wildlife movement and to maintain stream continuity (Figure 3). Further engineering is required to determine appropriate size and design to provide adequate flood capacity and stability.

The new guidance document is expected to be available in January 2019. High Risk Crossing Tables The following tables display the high risk road- stream crossings in Hawley. Each crossing has a Map ID that corresponds to a number on the High Risk Crossing Map. The Crossing ID for each entry was used to download data from two sources: the SHEDS Stream Crossing Explorer tool (data source for Overall Risk of Failure assessment), and the North Atlantic Aquatic Connectivity Collaborative (NAACC, data source for photos and Aquatic Passability assessment). The Crossing ID can be used to look-up crossings in either of these data sources (see the Instructions for Using Stream Crossing Data Tools).
