Maple Valley is located in south King County. According to the U. S. Census website, the population in 2019 was 27,202. The city is primarily residential, however, there is an increasing amount of commercial activity in the area.
The city of Maple Valley was officially incorporated on August 31, 1997. The main thoroughfare through the city is SR 169, or familiarly known as Maple Valley Highway. At the northern and southern boundaries of the city lie two large commercial areas, while central Maple Valley is predominantly residential.
The Four Corners district on the southside is the main commercial area of the city. It is located along Maple Valley Highway and is bisected by Kent-Kangley Road, officially known as SR 516 to create four distinct areas of development. The northwestern corner underwent massive reconstruction in the early 2010s and now features several large retailers, apartments, and a strip mall. The northeastern corner was completely constructed in the 2010s; it formerly was a large lumberyard and is now home to several retailers. The southern corners feature strip malls, retailers, an apartment complex, and a housing development.
The Green to Cedar River trail runs through the city, along SR 169 and Witte Road, which then connects to the Cedar River Trail and Lake Wilderness Park. The park includes a swimming beach, playground, and sprawling grass fields. The annual Maple Valley Days celebration is held here each year. The Lake Wilderness Arboretum is also located there as well as the Gaffney’s Grove Disc Golf Course and the Lake Wilderness Lodge. The Maple Valley Historical Society Museum, Maple Valley Community Center, library and skate park also border the park on the west side.
