Editing Davis, California (section)

==Geography and environment==

===Location===
Davis is located in [[Yolo County, California]], {{convert|18|km|abbr=on|order=flip}} west of [[Sacramento, California|Sacramento]], {{convert|113|km|abbr=on|order=flip}} northeast of San Francisco, {{convert|619|km|abbr=on|order=flip}} north of Los Angeles, at the intersection of [[Interstate 80 (California)|Interstate 80]] and [[California State Route 113|State Route 113]]. Neighboring towns include [[Dixon, California|Dixon]], [[Winters, California|Winters]], [[Woodland, California|Woodland]], and [[West Sacramento, California|West Sacramento]].

Davis lies in the [[Sacramento Valley]], the northern portion of the [[Central Valley (California)|Central Valley]], in [[Northern California]], at an elevation of about {{convert|52|ft|m}} above [[sea level]].

According to the [[United States Census Bureau]], the city has a total area of {{convert|10.5|sqmi|km2}}. {{convert|10.4|sqmi|km2}} of it is land and {{convert|0.04|sqmi|km2}} of it, or 0.19%, is water.

The [[topography]] is flat, which has helped Davis to become known as a haven for [[bicycle|bicyclists]].<ref>{{cite news|url=https://www.theguardian.com/cities/2015/aug/03/davis-california-the-american-city-which-fell-in-love-with-the-bicycle|title=Davis, California – the American city which fell in love with the bicycle|first=Carlton|last=Reid|date=August 3, 2015|newspaper=The Guardian|access-date=April 28, 2018|url-status=live|archive-url=https://web.archive.org/web/20170701173332/https://www.theguardian.com/cities/2015/aug/03/davis-california-the-american-city-which-fell-in-love-with-the-bicycle|archive-date=July 1, 2017}}</ref>

=== Climate ===
The Davis climate resembles that of nearby [[Sacramento, California|Sacramento]] and is typical of California's [[Central Valley (California)|Central Valley]] [[Mediterranean climate]] region: warm and dry in the spring, summer and autumn, and cool and wet in the winter. It is classified as a [[Köppen climate classification|Köppen]] ''Csa'' climate. Summer days are hot, ranging from {{convert|85|to|105|°F}}, but the nights turn pleasantly cool, almost always dropping below {{convert|70|°F}}. The Delta Breeze, a flow of cool marine air originating from the Pacific Ocean via [[San Francisco Bay]] and the [[Sacramento–San Joaquin River Delta]], frequently provides relief in the evening. Winter temperatures generally reach between {{convert|45|and|65|°F}} in the afternoon; nights average at about {{convert|35 to 40|°F}}, but occasionally fall below freezing.

Average temperatures range from {{convert|46|°F}} in December and January to {{convert|75|°F}} in July and August. Thick ground fog called [[tule fog]] settles into Davis during late fall and winter. This fog can be dense, with near zero visibility. As in other areas of Northern California, the tule fog is a leading cause of road accidents in the winter season.

Mean rainfall per annum is about {{convert|20|inch}}. The bulk of the rainfall occurs between about mid-November to mid-March, with typically no precipitation falling from mid-June to mid-September.<ref>{{cite web|url=https://weatherspark.com/y/1120/Average-Weather-in-Davis-California-United-States-Year-Round |title=Average Weather in Davis California, United States |publisher=Cedar Lake Ventures, Inc.|access-date=February 15, 2019}}</ref>

Record temperatures range from a high of {{convert|116|°F}} on July 17, 1925, to a low of {{convert|12|°F}} on December 11, 1932.<ref name="wrcc.dri.edu">{{cite web|url=http://www.wrcc.dri.edu/cgi-bin/cliMAIN.pl?ca2294 |title=DAVIS 1 WSW, CALIFORNIA – Climate Summary |publisher=Wrcc.dri.edu |access-date=June 19, 2013 |url-status=live |archive-url=https://web.archive.org/web/20140811223156/http://www.wrcc.dri.edu/cgi-bin/cliMAIN.pl?ca2294 |archive-date=August 11, 2014 }}</ref>

===Neighborhoods===
{{More citations needed section|date=May 2024}}
Davis is internally divided by two freeways ([[Interstate 80 in California|Interstate 80]] and [[California State Route 113|State Route 113]]), a north–south railroad (California Northern), an east–west mainline (Union Pacific) and several major streets. The city is unofficially divided into six main districts made up of smaller neighborhoods (often originally named as housing [[Subdivision (land)|subdivisions]]):
[[Image:UC Davis arboretum - ducks.jpg|thumb|The [[University of California, Davis Arboretum|UC Davis Arboretum]]]]

* Central Davis, north of Fifth Street and Russell Boulevard, south of Covell Blvd., east of SR 113, and west of the railroad tracks running along G Street. Within these boundaries is the officially denoted neighborhood of Old North Davis, which is sometimes also considered part of Downtown.<ref>{{Cite web|url=https://localwiki.org/davis/Central_Davis|title=Central Davis|website=LocalWiki|access-date=March 17, 2017|url-status=live|archive-url=https://web.archive.org/web/20170413071450/https://localwiki.org/davis/Central_Davis|archive-date=April 13, 2017}}</ref>{{Better source needed|reason=The current source is insufficiently reliable as it links to an external wiki site which has no sourcing. ([[WP:NOTRS]]).|date=May 2024}}
* Downtown Davis, roughly the numbered-and-lettered grid north of I-80, south of Fifth Street, east of A Street, and west of the railroad tracks, including the Aggie Village and Olive Drive areas.<ref>{{Cite web |title=El Macero - Welcome to El Macero |url=https://www.elmacerohoa.com/ |access-date=September 2, 2023 |website=www.elmacerohoa.com}}</ref>
* East Davis, north of I-80, south of Covell Blvd., and east of the railroad tracks. It includes the older, 'inner' East Davis of lettered streets and neighborhoods such as Davis Manor, Chestnut, and Rancho Yolo, as well as more distinctly identified (in some cases walled-in) subdivisions such as Mace Ranch, Lake Alhambra Estates, and Wildhorse.{{Citation needed|date=July 2014}}
* North Davis, north of Covell Blvd. North Davis includes Covell Park, Senda Nueva, Northstar, and North Davis Farms.
* South Davis, south of I-80, and includes Willowbank. [[El Macero, California]], although outside the city limits, is sometimes considered part of South Davis; El Macero is part of the [[Davis Joint Unified School District]], and El Macero children who attend public schools attend Davis' public schools.{{Citation needed|date=July 2014}}
* West Davis, north of I-80 and west of SR 113. West Davis includes Westwood, Evergreen, Aspen, Stonegate (west of Lake Boulevard and including Stonegate Lake and the Stonegate Country Club) and the eco-friendly [[Village Homes]] development, known for its solar-powered houses.

The [[University of California, Davis]] is located south of Russell Boulevard and west of A Street and then south of 1st Street. The land occupied by the university is not incorporated within the boundaries of the city of Davis and lies within both Yolo and Solano Counties.

=== Environment ===
Local energy planning began in Davis after the energy crisis of 1973. A new building code promoted [[energy conservation|energy efficiency]]. Energy use in buildings decreased dramatically and in 1981 Davis citizens won a $100,000 prize from utility [[PG&E]], for cutting electricity use during the summer peak.<ref>''Lovins on the Soft Path: A Guide to the Film'', [[Rocky Mountain Institute|RMI]], 1985.</ref>

On November 14, 1984, the Davis [[City Council]] declared the city to be a [[nuclear-free zone]].<ref>{{cite web|url=http://daviswiki.org/Nuclear_Free_Zone|title=Nuclear Free Zone – Davis – LocalWiki|website=daviswiki.org|access-date=April 28, 2018|url-status=live|archive-url=https://web.archive.org/web/20170525170705/https://daviswiki.org/Nuclear_Free_Zone|archive-date=May 25, 2017}}</ref> In 1998, the City passed a [[Dark-sky movement|"Dark Skies"]] ordinance in an effort to reduce [[light pollution]] in the night sky.<ref>McCarthy, E.[http://www.bizjournals.com/sacramento/stories/1999/02/01/focus3.html?page=all "'Dark skies' law casts new light on buildings"] {{webarchive|url=https://web.archive.org/web/20140219221513/http://www.bizjournals.com/sacramento/stories/1999/02/01/focus3.html?page=all |date=February 19, 2014 }} ''Sacramento Business Journal'', January 31, 1999.</ref>

In 2013, Davis became part of the state [[Reflective surfaces (climate engineering)|Cool Roof]] Initiative with the "CoolDavis" campaign, requiring all new roofing projects to meet Cool Roof Rating Council (CRRC) requirements, including the installation of light-colored roofs. The aim is to reflect more sunlight back into space via the [[albedo]] effect, and reduce the amount of heat absorbed in hopes of limiting climate change.<ref>{{Cite web|url=https://www.cooldavis.org/category/energy/|title=Energy Archives – Cool Davis|website=Cool Davis|language=en-US|access-date=July 12, 2018|archive-url=https://web.archive.org/web/20180712053956/https://www.cooldavis.org/category/energy/|archive-date=July 12, 2018|url-status=live}}</ref>
