Editing Maple Valley, Washington (section)

===Incorporation and recent development===
The city of Maple Valley was officially incorporated on August 31, 1997. The Green to Cedar River trail runs through the city, along [[Washington State Route 169|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|date=May 2019}}

Due to the urban growth boundaries of [[King County, Washington|King County]], the city is uniquely split into different sectors along Maple Valley Black Diamond Road (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.<ref>{{Cite web |title=Urban Growth Areas for King County |url=https://www5.kingcounty.gov/sdc/Metadata.aspx?Layer=urban_growth |access-date=June 13, 2023 |website=King County GIS Center}}</ref>

The south side's Four Corners district is the main commercial area of the city.
