  2. Development of preliminary designs and implementation plans that will address water quality impairments in impaired watersheds;
  3. Development of Watershed-based Plans for 319 grant Healthy Waterbody Projects to be used to guide watershed protection and management activities;
  4. Determination of the nature, extent, and causes of water quality problems and determination of pollutant load reductions necessary to meet water quality standards; or
  5. Development of green infrastructure projects that manage wet weather events to maintain or restore natural hydrology
