Include information on fossil resources, the geology and bedrock in which fossils are found, the sensitivity of the information available for the project, monitoring, mitigation and reporting procedures if fossils are encountered during construction;

(b) Methods of monitoring procedures to be used during construction including proposed tools and equipment for documenting discoveries;

(c) Communication protocols to be followed if a fossil discovery is made during construction

(d) Mitigation recommendations, in detail, including; preparation, curation, final reporting requirements;

(e) Methods and proposed forms for documenting fossil discoveries. Include with documentation photographs, observational notes, geospacial coordinates, contextual data.

Incorporate this information into the final report for the project.
