After more than 15-years of planning, the development of the 1,400-acres known as South Hillsboro has broken ground. Bordered on the south by Rosedale Road, on the north by Tualatin Valley Highway, and lying between SW 229th Avenue and the existing Urban Growth Boundary to the west and SW 209th Avenue on the east, this new community will be home to 8,000 houses and 20,000 new residents. South Hillsboro’s master plan also provides 286-acres of new parks and open space, 15-miles of trails, and a multi-modal transportation network featuring world-class bicycle infrastructure and sidewalks.
The years of planning and developer negotiations has led to the adoption of a development-funded Finance Plan calling for $450-million in infrastructure investment. More information about the South Hillsboro development can be found at: www.Hillsboro-Oregon.gov/SouthHillsboro
Development of the South Hillsboro area will occur in phases, with full development anticipated over the next 20 years. Site and infrastructure improvements have begun on Reed’s Crossing, the north portion of the South Hillsboro area. Home construction in Reeds Crossing is scheduled to start in late 2017/early 2018.
Development of South Hillsboro requires the partnership and coordination of multiple agencies and infrastructure projects. Currently, the Willamette Water Supply Program is coordinating with the City of Hillsboro, Washington County, and Newland Communities on the following projects:
- The drinking water transmission pipeline will be placed under Cornelius Pass Road in coordination with the improvements being made to the Cornelius Pass/TV Highway Intersection project in 2017.
- The drinking water transmission pipeline will be placed in the future Cornelius Pass Road roadway running through Reed’s Crossing.
Future partnership opportunities in the South Hillsboro area include:
- Design and construction of Washington County’s expansion of Cornelius Pass Road, from just north of the Cornelius Pass/TV Highway intersection to Francis Street, will be done in partnership with the extension of the Willamette Water Supply Program pipeline north.
- In coordination with the City of Hillsboro, the Willamette Water Supply Program pipeline will be located in the future Cornelius Pass Road right-of-way south of Blanton Street to Rosedale Road.
The coordinated construction of the pipeline and the Cornelius Pass Road improvements and extension will result in significant cost savings for water ratepayers, minimize community and neighborhood impacts, and eliminate the need for multiple construction projects.
