The National Park Service (NPS) has issued new additional Information supplementing the Historic Preservation Certification Application (HPCA) Instructions for Part 2 applications and Amendments on phasing, phased rehabilitation projects, and phase advisory determinations for the purposes of NPS certification for Federal historic preservation incentives. Applicants typically elect to phase a rehabilitation project if they are intending to substitute the IRS 60-month measuring period, later request advisory determinations, or because complete information for later phases of work may not yet be known or available.
