Maple Valley is a city in King County, Washington, United States. The population was 22,684 at the 2010 census, and is estimated to be 27,114 as of 2018.[5] The city functions as a commuter town for residents, though there is an increasing amount of commercial activity in the area.


The area was settled in 1879 by three men who were improving a trail and brought their families in. When a name for a future community was proposed, the names Vine Maple Valley and Maple Ridge were suggested. A vote was taken by writing the names on slips of paper and placing them in a hat. Vine Maple Valley won by 2/3, but the word "Vine" was later cut by the post office because it made the name too long.[6]

The town's early history mainly had to do with coal, lumber milling to build homes, and a railroad that ran through town. Coal was brought in from Black Diamond to the south, but the town itself also mined coal from Cedar Mountain. The mine was used as late as 1947. Rail workers for lines like the Northern Pacific Railroad and the Cedar River Watershed, closed off by the City of Seattle, meant more workers for those things. More residents meant more lumber milling. More lumber milling meant more workers. Suquamish tribe chairperson Martha George was born near Maple Valley in Sheridan in 1892, at a logging camp where her mother and grandmother worked as cooks."[7]

The town grew inward. Blacksmith shops, hotels, saloons and stores took up the town in the 1910s and 1920s. Schools went up as well. Early schools were shacks at best. A two-room school went up in 1910, and a larger high school was built in 1929 as the first school in the Tahoma School District.[8] The school, after extensive renovations, still stands today as an elementary school. Much of this early development actually did not take place in the modern-day city, but rather in Hobart, northeast of incorporated Maple Valley.

More residents meant farming and fishing became staples in the area, with milk, poultry and berry farming becoming the main grown food staples in the area. Fishing out of the Cedar River also became popular. Maple Valley also saw resorts beginning in the 1920s. Lake Wilderness, once the site of a county lumber mill, quickly became a resort lake with the opening of Gaffney's Grove, which opened with a ballroom, restaurant and roller rink. Later, the resort grew to include an airstrip, lodge, rental cabins, a nine-hole golf course and a bowling alley. It remained in operation until 1964.[9]

Increasing automobile use in the area gave rise to new roads being built. In the early 1960s, the construction of State Route 18 between Auburn and North Bend ran through the city, requiring many landmarks to be either demolished or moved.[6] The Maple Valley Historical Society keeps records on the city's past, with two historical museums holding artifacts such as the city's first fire engine and photographs of old places in and around the city like Gaffney's Grove.[citation needed]

Incorporation and recent development[edit]

The city of Maple Valley was officially incorporated on August 31, 1997. The Green to Cedar River trail runs through the city, along SR 169 and Witte Road while passing through the former Gaffney's Grove site, now the Lake Wilderness City Park. The park includes a swimming beach and sprawling grass fields, and sees the annual Maple Valley Days Parade each year in June. The Lake Wilderness Arboretum is also located here.[citation needed]

Due to the urban growth boundaries of King County, the city is uniquely split into different sectors along Maple Valley Highway (SR 169), the main thoroughfare through the city. At the northern and southern boundaries of the city lie two large commercial areas, while central Maple Valley is predominantly residential.[10][citation needed]

The south side's Four Corners area is the main commercial area of the city and is located at the intersection of Maple Valley Highway and Kent-Kangley Road (SR 516.[11] The northeastern corner underwent massive reconstruction in the early 2010s and now features several large retailers and a strip mall.[12][unreliable source?] The northwestern corner was completely constructed in the 2010s; it formerly was a large lumberyard and is now home to several retailers.[13][unreliable source?]

The city, entirely served by the Tahoma School District, which had its sole high school in Covington. In 2015, a bond measure was passed to build a new high school for the district in a small unincorporated area southeast of Four Corners that was completely surrounded by Maple Valley.[14] The area was annexed into Maple Valley and the new three-story Tahoma High School was completed in 2017.[15]


Maple Valley is located at 47°21′58″N 122°2′41″W / 47.36611°N 122.04472°W / 47.36611; -122.04472 (47.366160, -122.044692).[16] According to the United States Census Bureau, the city has a total area of 5.90 square miles (15.28 km2), of which, 5.72 square miles (14.81 km2) is land and 0.18 square miles (0.47 km2) is water.[17]

The main bodies of water in the city limits are Lake Wilderness, Lake Lucerne, Rock Creek, and part of Pipe Lake. The Cedar River passes through unincorporated King County very near the northeastern border of the city. The city is bordered by Hobart, Fairwood, and Ravensdale, two unincorporated King County census-designated places, along with the cities of Renton, Kent, and Black Diamond.
