NFPA 1031, Standard for Professional Qualifications for Fire Inspector and Plan Examiner, does not provide specific details regarding the number of fire hydrants on a specific project site or plan. NFPA 1031 outlines the qualifications and job performance requirements for professionals, such as Fire Plan Examiners, responsible for reviewing fire protection systems and ensuring code compliance.

For determining the number of fire hydrants on a project site as indicated on plan L2, you will need to reference the specific project documents or site plans, which are not included in the provided files. A Fire Plan Examiner, according to NFPA 1031, would need to review the site plans, including plan L2, to identify the number and locations of fire hydrants. The examiner uses skills and knowledge, as defined in NFPA 1031, to evaluate and ensure the plans meet the required fire protection standards and codes, including ensuring adequate fire hydrant placement for fire safety and emergency access.

If further details or clarification about specific project documents are needed, consulting the actual site plan or reaching out to the relevant authorities, such as the local fire marshal or project manager, would be essential.
