Bid Description:
The Vermont Geological Survey (VGS), a Division within the Department of Environmental Conservation (DEC) has been involved with landslide assessment and mapping for many years. Along with our partners, the State of Vermont (hereinafter the “State”) has performed landslide inventories for five of 14 counties in Vermont and created a “Report a Landslide” web tool that allows citizens to report landslide observations. The State’s landslide database has grown to include over 3000 documented landslides and unstable gullies. Even as the State’s inventory grew, the magnitude of vulnerability was not made fully clear until the aftermath of the July 2023 storm, when dozens of landslides were initiated by heavy precipitation and soil saturation. The State and our partners received requests to visit over 80 locations to assess hazards associated with slope instability. Since the July 2023 storm, the State has received multiple inquiries into Vermont’s susceptibility to future high-magnitude landslide-triggering events, and specifically for maps of susceptibility. The State is beginning to fill the need for these maps for the eastern portion of
Vermont: this Request for Proposals is to provide susceptibility mapping coverage for the Vermont Piedmont and Northeast Highlands provinces (the Area of Interest, or “AOI”).
This project aims to establish a multivariate analysis method in a geographical information system (GIS) that is capable of identifying landslide-prone areas. Topographic datasets including slope steepness and stream.
Proximity will be derived from the best available Light Detection and Ranging (LiDAR) topographic data and used along with other terrain elements including bedrock outcrops, landcover, soil erodibility, and hydrologic groups. Each of these parameters will be incorporated into a multivariate analysis using a weighted overlay function in ArcMap GIS to create composite risk assessment maps. The State is seeking proposals for this work with up to $16,375.00 available for compensation in the period April 15, 2024, to September 15, 2024. The sub-awardee must document third-party match of $16,375.00.
