Moshier Memorial Park and Parking Lot Improvements

Project Status

Construction began in late August 2021 and is expected to be complete in March 2022. The park will be closed to the public throughout the construction period. The parking lot will have limited access for high school and Moshier Art use during construction. Overflow parking will be available at Sunnydale Elementary School, diagonally across the street at 15623 Des Moines Memorial Drive, Burien.

Project Timeline

The construction of the project is anticipated to take six months to seven months, between late August 2021 and is expected to be complete in March 2022.

Project Overview

The project will construct improvements at Moshier Memorial Park including:

  • Retrofit stormwater management in the park and the adjacent parking lot to greatly reduce untreated stormwater flowing into Miller-Walker Creek Watershed region. This project will implement several Low Impact Development Best Management Practices (BMPs) to improve water quality and reduce the volume and peak stormwater runoff discharges rates leaving the site. This project has been determined to have the highest benefit value in the entire region for stormwater improvements.
  • Convert an existing grass baseball field, Field 1, into a year-round, all-purpose sports field that will support baseball, softball, youth soccer, and lacrosse and practices for other sports such as football or cricket. The grass will be replaced with synthetic turf called Rootzone by AstroTurf and the infill material will be Brockfill, which is an organic U.S.-sourced material. This new field will increase available field use time for local youth organizations, as the field will be available for use year-round.
  • Construct ADA-accessible pathways from the parking lot to the restroom, ballfields, and grandstand that meet Americans with Disabilities Act (ADA) requirements. The project will also construct ADA-compliant seating in the grandstand.
  • Replace existing restrooms with ADA-compliant restrooms. This will allow more equitable use of the facility.
