  • USACE issues permit authorizing California wildfire mitigation activities in waters of the United States

    The U.S. Army Corps of Engineers has issued Regional General Permit (RGP) 10, authorizing activities associated with wildfire mitigation that may involve discharge of dredged or fill material into waters of the United States and/or work in or affecting navigable waters of the United States, including wetlands, within the State of California.
  • Headwaters Highlights: Regulators ‘mount up’ to defend waterways and wetlands in Pittsburgh’s watersheds

    Unlike the gun-slinging outlaws of the 1870s bringing violence to the Western frontier in New Mexico, or the Warren G rappers of the 1990s cruising to the Eastside Motel in Los Angeles, today’s regulators “mount up” for a very different reason in the Pittsburgh District.
  • Antecedent Precipitation Tool (APT) Version 2.0: Technical and User Guide

    Purpose: This document provides an overview of the technical components of the Antecedent Precipitation Tool (APT) and a user’s guide for the APT. The APT is an automation tool that the US Army Corps of Engineers (USACE) developed to facilitate the comparison of antecedent or recent precipitation conditions for a given location to the range of normal precipitation conditions that occurred during the preceding 30 yr*. In addition to providing a standardized methodology to evaluate normal precipitation conditions (precipitation normalcy), the APT queries additional datasets to assess the presence of drought conditions and the approximate dates of the wet and dry seasons for a given location. This document constitutes an update to Antecedent Precipitation Tool (APT) Version 1.0: Technical and User Guide (Gutenson and Deters 2022).
  • From Antiquated to Automated: USACE wetland delineation tool helps revolutionize regulatory process

    According to the Environmental Protection Agency, United States has lost more than half of its wetlands since the 1600s, and approximately 35 percent of the world’s wetlands were lost between 1970 and 2015. To protect against further impairment of wetlands and the essential functions they provide, the U.S. established a policy of "no net loss" of wetlands, as well as procedures to ensure responsible management of wetland resources.
  • Eelgrass Functions, Services, and Considerations for Compensatory Mitigation

    Abstract: Coastal-marine eelgrass habitat is a critical resource within New England and throughout the world. Eelgrass habitat provides functions and services including providing structure, biogeochemical cycling, erosion reduction, habitation provision, and water quality improvement. Declines in eelgrass distribution are often due to anthropogenic processes impacting temperature and water quality. Declines in distribution and abundance highlight the importance of protecting the existing eelgrass, improving environmental conditions allowing for ecosystem restoration, and identifying viable in-kind and out-of-kind compensatory mitigation measures. Considering the limited availability of New England sites for in-kind compensatory mitigation, additional approaches for out-of-kind compensatory mitigation should be considered. These include (1) creation of alternative plant or kelp habitat, (2) using a multi-pronged, multi-habitat and structure approach, (3) contributing to the development of water quality improvement initiatives to encourage current eelgrass bed expansion over time, (4) reduce physical impacts to eelgrass habitat, (5) and identifying locations for future eelgrass habitat suitability based on climate predictions and investing to create future compensatory mitigation habitat in these locations.
