Abstract: Savan Gut (also known locally as Deyoung Gut) is located in the highly developed urbanized area of Charlotte Amalie, St. Thomas, United States Virgin Islands. The gut’s headwaters begin in the mountainous and heavily vegetated region north of the Charlotte Amalie Harbor. The gut drains directly into the harbor via a natural gut from the vegetated area, to a combination of an intermixed lined and unlined degraded concrete channel from the Jane E. Tuitt Elementary School (flowing under the school and the schools’ basketball court) to the intersection of Guttets Gade and Norte Gade. The culvert is then inaccessible and flows underneath businesses and roads of downtown Charlotte Amalie until it exits into St. Thomas Harbor. The purpose of the project is to reduce flood damages to the Jane E. Tuitt Elementary School and Central Business District in downtown Charlotte Amalie. Heavy rainfall in the upland catchment basin of Savan Gut causes rocks and other debris to be washed down the channel toward the sea. Two constrictions reduce flood flows so that the flood waters overflow the channel banks and flood the school as well as the business district. The Savan section of Charlotte Amalie has extremely high runoff rates due to the steep slopes in the upper basin. Flash floods from intense thunderstorms are a common event affecting this area and can occur anytime during the year. Effects from Hurricane Maria, which hit the island in September 2017, prompted the Corps to include the project for consideration for funding under the BBA. (Effects from the storm are discussed more in this EA’s section 3.5 Hurricane Maria Storm Effects.) This Environmental Assessment (EA) evaluates the Recommended Plan, which is described in detail in Section 2.2. This EA also completes the required analysis under the National Environmental Policy Act (NEPA) and adopts the 1982 EA by reference where the information is valid and applicable to this evaluation.
