Plain-English explanation

Editorial analysis

What the funder is trying to accomplish

The program describes support for multi-benefit projects that advance listed conservation, hazard-reduction, water-quality, habitat, public-access, recreation, native-habitat, invasive-species, and San Diego River cultural or tribal-preservation outcomes.

Editorial analysis

Strong-fit project signals

The applicant is a nonprofit, public agency, or tribal government. The project is located in the San Diego River Watershed or the Sweetwater, Otay, or Tijuana Rivers watersheds. The project advances multiple listed outcomes, such as land conservation, flood or fire-risk reduction, water-quality improvement, and wildlife-habitat or corridor protection or enhancement. The project includes a listed San Diego River-oriented outcome, where applicable, such as San Diego River Trail completion, public access to the River Park or open space and related facilities, invasive-plant removal, or native-habitat and species re-establishment. The project promotes cultural or tribal preservation or historical interpretation of the San Diego River and its people.

Editorial analysis

What reviewers may prioritize

Formal reviewer criteria and scoring weights are not supplied in the packet. As an inference from the eligibility and program description, a competitive narrative should make the project’s watershed location and its connections to multiple listed outcomes clear; this is not confirmed scoring guidance.
