5. Description of project: (Describe the whole action involved, including but not limited to later phases of the project, and any secondary, support, or off-site features necessary for its implementation. Attach additional sheets if necessary. The description may be a summary with a reference to other documents that contain the detailed project description.)
EVALUATION OF THE ENVIRONMENTAL IMPACTS IN THE CHECKLIST
1. The board must complete an environmental checklist prior to the adoption of plans or policies for the Basin/208 Planning program as certified by the Secretary for Natural Resources. The checklist becomes a part of the Substitute Environmental Documentation (SED).
2. For each environmental category in the checklist, the board must determine whether the project will cause any adverse impact. If there are potential impacts that are not included in the sample checklist, those impacts should be added to the checklist.
3. If the board determines that a particular adverse impact may occur as a result of the project, then the checklist boxes must indicate whether the impact is “Potentially Significant,” “Less than Significant with Mitigation Incorporated,” or “Less than Significant.”
a. “Potentially Significant Impact” applies if there is substantial evidence that an impact may be significant. If there are one or more “Potentially Significant Impact” entries on the checklist, the SED must include an examination of feasible alternatives and mitigation measures for each such impact, similar to the requirements for preparing an environmental impact report.
b. “Less than Significant with Mitigation Incorporated” applies if the board or another agency incorporates mitigation measures into the SED that will reduce an impact that is “Potentially Significant” to a “Less than Significant Impact.” If the board does not require the specific mitigation measures itself, then the board must be certain that the other agency will in fact incorporate those measures.
c. “Less than Significant” applies if the impact will not be significant, and mitigation is therefore not required.
d. If there will be no impact, check the box under “No Impact.”
4. The board must provide a brief explanation for each “Potentially Significant,” “Less than Significant with Mitigation Incorporated,” “Less than Significant,” or “No Impact” determination in the checklist. The explanation may be included in the written report described in section 3777(a)(1) or in the checklist itself. The explanation of each issue should identify: (a) the significance criteria or threshold, if any, used to evaluate each question; and (b) the specific mitigation measure(s) identified, if any, to reduce the impact to less than significant. The board may determine the significance of the impact by considering factual evidence, agency standards, or thresholds. If the “No Impact” box is checked, the board should briefly provide the basis for that answer. If there are types of impacts that are not listed in the checklist, those impacts should be added to the checklist.
5. The board must include mandatory findings of significance if required by CEQA Guidelines section 15065.
6. The board should provide references used to identify potential impacts, including a list of information sources and individuals contacted.

II. AGRICULTURE AND FOREST RESOURCES:
In determining whether impacts to agricultural resources are significant
environmental effects, lead agencies may refer to the California Agricultural Land
Evaluation and Site Assessment Model (1997) prepared by the California Dept. of
Conservation as an optional model to use in assessing impacts on agriculture and
farmland. In determining whether impacts to forest resources, including timberland,
are significant environmental effects, lead agencies may refer to information compiled
by the California Department of Forestry and Fire Protection regarding the state's
inventory of forest land, including the Forest and Range Assessment Project and the
Forest Legacy Assessment Project; and forest carbon measurement methodology
provided in Forest Protocols adopted by the California Air Resources Boards.

Explanations of Impact Assessment (may also follow checklist sections)
PRELIMINARY STAFF DETERMINATION
The proposed project COULD NOT have a significant effect on the environment, and, therefore, no alternatives or mitigation measures are proposed.
The proposed project MAY have a significant or potentially significant effect on the environment, and therefore alternatives and mitigation measures have been evaluated.
