Lake Sammamish and the adjacent plateau has been [[Duwamish people|Duwamish]], [[Suquamish]], [[Snoqualmie people|Snoqualmie]], [[Sammamish people|Sammamish]], and [[Snohomish people|Snohomish]] territory since the [[Pleistocene glaciation|last Pleistocene glaciation]], before contact with European people.<ref name=":1">{{cite web |last=Dougherty |first=Phil |date=December 23, 2013 |title=Sammamish — Thumbnail History |url=https://www.historylink.org/File/10689 |access-date=October 30, 2023 |work=[[HistoryLink]]}}</ref> They lived in longhouse villages in seven places on and near the coast of Sammamish Lake.

The Sammamish Plateau was part of unincorporated [[King County, Washington|King County]] for most of its recorded history. The first settlers arrived in the 1870s<ref name=":1" /> and established a trio of resorts by the 1930s. The [[plateau]] remained a mostly rural area until suburban homes, shopping centers, and schools were built in the 1970s and 1980s. However, from approximately 1900 through the [[Great Depression in the United States|Great Depression]], there was a tiny [[Hamlet (place)|hamlet]] in Inglewood community (at today's Weber Point) of approximately 50 people who called the area "Sammamish", and later, in the 1960s, there was a suburban community and [[Sunny Hills Elementary|school]] at what is now Sunny Hills.<ref name=":1" /> A vote in 1991 to join neighboring [[Issaquah, Washington|Issaquah]] failed, as did a vote on incorporation the following year. A renewed movement to become a city, born of frustration with development policies set by the county government, met with voter approval in 1998. Sammamish was officially incorporated on August 31, 1999.<ref>{{cite web |last=Dougherty |first=Phil |date=April 24, 2008 |title=Sammamish incorporates on August 31, 1999 |url=http://www.historylink.org/File/7466 |work=[[HistoryLink]] |access-date=June 22, 2011}}</ref> The city annexed [[Klahanie, Washington|Klahanie]] on January 1, 2016.<ref>{{cite news|url=http://www.issaquahreporter.com/news/363747121.html|title=Officially Sammamish: Klahanie annexation brings city's population to more than 60,000|work=Issaquah Reporter|access-date=July 7, 2016}}</ref>

The city government approved plans in 2008 to develop a denser [[town center]] with [[mixed use development|mixed use]] zoning and taller buildings. The first two residential buildings and several commercial developments were completed over the following decade, but plans for the largest phase stalled into the 2020s.<ref>{{cite news |last=Groover |first=Heidi |date=October 5, 2021 |title=Sammamish, like many suburban Seattle cities, gripped by development fight as region's population booms |url=https://www.seattletimes.com/business/real-estate/sammamish-like-many-suburban-seattle-cities-gripped-by-development-fight-as-regions-population-booms/ |work=The Seattle Times |accessdate=May 21, 2024}}</ref> Construction began in 2024 on 38 townhomes in the phase, which is planned to be followed by more townhomes, 600 [[market rate]] apartments, and commercial space.<ref>{{cite news |last=Groover |first=Heidi |date=May 20, 2024 |title=Sammamish finally proceeds with major housing, commercial project |url=https://www.seattletimes.com/business/real-estate/sammamish-finally-proceeds-with-major-housing-commercial-project/ |work=The Seattle Times |accessdate=May 21, 2024}}</ref>

==Geography==
According to the [[United States Census Bureau]], the city has a total area of {{convert|24.04|sqmi|sqkm|2}}, of which {{convert|20.43|sqmi|sqkm|2}} are land and {{convert|3.61|sqmi|sqkm|2}} are water.<ref name="CenPopGazetteer2024"/>

The city is situated on the shores and hilly terrain east of [[Lake Sammamish]]. It is bordered to the south by [[Issaquah, Washington|Issaquah]], to the northwest by [[Redmond, Washington|Redmond]], and to the west across Lake Sammamish by [[Bellevue, Washington|Bellevue]]. [[Beaver Lake (King County, Washington)|Beaver Lake]] and [[Pine Lake (Washington)|Pine Lake]] are the two biggest lakes in Sammamish. [[Yellow Lake (Sammamish, Washington)|Yellow Lake]] is a major lake in Klahanie.

Sammamish is in and near the [[Issaquah Alps]], a westward extension of the [[Cascade Range|Cascade]] foothills.<ref name=":2">{{Cite web |date=October 28, 2023 |title=Cougar/Squak Corridor |url=https://kingcounty.gov/en/dept/dnrp/nature-recreation/parks-recreation/king-county-parks/trails/backcounty-trails/cougar-squak-corridor |website=KingCounty.gov}}</ref>

===Climate===
The city has a [[warm-summer Mediterranean climate]] ([[Köppen climate classification|Köppen]]: ''Csb''), or [[Oceanic climate|oceanic]] ([[Köppen climate classification|Köppen]]: ''Cfb'') if the {{Convert|30|mm|in}} [[isohyet]] is used. Due to the [[Rain shadow|rain shadow effect]] of the [[Olympic Mountains]] to the west, summers are much drier here than on the immediate west coast of Washington.<ref>{{Cite web |title=Aberdeen climate: Average Temperature by month, Aberdeen water temperature |url=https://en.climate-data.org/north-america/united-states-of-america/washington/aberdeen-16187/ |access-date=May 10, 2024 |website=en.climate-data.org}}</ref>

Winters are cool and wet; the wettest months are November, December, and January, when the area is directly affected by the [[Aleutian Low]], and summers are warm and dry; the driest months are July and August. Snowfall is rare; subfreezing temperatures usually occur with a [[High-pressure area|high-pressure system]], which brings clear skies. Extremes range from {{convert|-8|F}} in February 1950, to {{convert|113|F}} in [[2021 Western North America heat wave|June 2021]].

Sammamish is in [[hardiness zone]] 8b, with small southwestern pockets as well as the immediate Lake Sammamish coast falling into type 9a.<ref>{{Cite web |title=2023 USDA Plant Hardiness Zone Map {{!}} USDA Plant Hardiness Zone Map |url=https://planthardiness.ars.usda.gov/ |access-date=January 22, 2024 |website=planthardiness.ars.usda.gov}}</ref>

===Climate change===
Sammamish is predicted to warm by 3-12 F (2-7 C) before 2100 regardless of future emissions, and around 2.5 F during the next few decades due to [[climate change]]. Warming by any significant amount will cause Sammamish to have reduced snowfall, hotter and drier summers, and more warm-season extreme weather events.<ref name=":3">{{Cite web|date=October 20, 2023 |title=Critical Areas Ordinance Update – City of Sammamish |url=https://www.sammamish.us/media/ufubtobg/sammamish-cao_bas-report_10-20-2023.pdf}}</ref>
