Editing Napa, California (section)

==Geography==
According to the [[United States Census Bureau]], the city has a total area of {{convert|18.1|sqmi|km2}}, of which {{convert|17.8|sqmi|km2}} is land and {{convert|0.3|sqmi|km2}}, or 1.69%, is water. Napa was the first location in California to be part of the North Coast [[American Viticultural Area]].<ref>{{cite web|url=https://napavintners.com/napa_valley/|title=Napa Valley American Viticultural Area|website=Napa Vintners}}</ref> Renowned for its wine due to the Mediterranean climate, surprisingly only about 9% of Napa's acreage is planted with grapes.<ref>{{cite web|title=Napa Vinters|url=https://napavintners.com/napa_valley/|website=Napa Vintners}}</ref>

The [[Napa River]] traverses the city on its journey to the [[San Pablo Bay]]. The city has conducted a variety of waterfront development along the banks of the river, including certain fill operations governed by the United States Army Corps of Engineers regulations.<ref name="AutoCK-24"/> The Napa River Flood Project has been in progress since the late 1990s, with the goal of mitigating the risk of flooding along a {{convert|6|mi|km|adj=on}} stretch of the river and {{convert|1|mi|km|adj=on}} of Napa Creek.
