Why it's listed

Port Chicago Naval Magazine National Memorial is a historic district located at 4202 Alhambra Avenue in Martinez, Contra Costa County, California. It was listed on the National Register of Historic Places on October 28, 2009, under reference number 11000237. The record available here is an administrative locator card rather than a full nomination, and it is flagged as an automatic listing with undocumented National Park Service status. Because of that, the card contains no physical description of the site, no construction dates, no named designers or builders, and no explanation of the events or themes behind its recognition. Only the name, address, county, listing date and category can be confirmed from this material. Anyone seeking details on the district's history, boundaries or condition would need to consult other source documentation, since none is included in this record.

What listing means for this property

This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
