Schuster Slope

Schuster 1893

One of the defining characteristics of the Puget Sound region is the dynamic coastline, which includes more than 1,400 miles of beaches built out of sands and gravels from nearby bluffs.  These actively eroding bluffs, including Schuster Slope, are an essential part of our coastal ecosystems.  They provide a significant amount of coastal forest, support nesting birds and raptors, serve as refuge for native wildlife, and provide sediment and nourishment to our beaches as they erode along the shoreline.


Site Conditions

Schuster 2015Schuster Slope is located along the west shore of Commencement Bay in Tacoma. The lack of healthy vegetation on the steep slopes, along with frequent rainfall, causes Schuster Slope to experience skin slides, debris flows and sloughing as it tries to revert to its pre-development, natural feeder bluff state.

Slope stability has been the focus of two previous City-led studies conducted by GeoEngineers, the first in 2000 and the second in 2014.

The entire Schuster Slope area is classified as a Critical Area under Tacoma Municipal Code (TMC) 13.11 due to the steep slopes, wetlands, streams, and priority habitat (as defined by the Washington Department of Fish and Wildlife). For long-term management activities to occur, a 20-year permit under TMC 13.11 Critical Areas Preservation Code will allow Environmental Services to efficiently move forward with restoration actions and improve the slope stability.


Landscape Management Plan

In 2014, the City began a public process to create a landscape management plan for the Schuster Slope. The goal was to ensure the new plan was reflective of the current conditions, best available science, and regulation compliance.



Metro Parks Tacoma provided assistance with outreach while GeoEngineers and Landau Associates provided scientific analysis.

The result of the City's efforts is a 20-year landscape management plan built on the concept of achieving a target ecosystem composition to maximize the ecosystem services that Schuster Slope can provide. The vegetative management goals for the project area include:

  • Achieving a sustainable target ecosystem
  • Improving slope stability
  • Maximizing stormwater benefit
  • Increasing public safety and infrastructure protection

The management plan’s success depends on effective implementation and regular updates to incorporate the best available science and management techniques.

Schuster Slope Work Implementation

The management plan is well under way with planting completed in the first two Management Units located at the southern end of the slope and along S. Stadium Way.  Some planting has also occurred in Management Units 8 and 9.  Monitoring of habitat restoration areas has been going on for the past four years, and the collected data has been used to adaptively manage new work.

A long 3-acre band along the top of slope from South 4th Street to Division Way was worked over by City staff, pruning unhealthy limbs on many damaged and coppiced trees. A total of 179 individual trees were pruned, surveyed with handheld GPS units, and physically tagged. Click on the link below to view the new 2.8 acre work unit and the location of pruned trees.

Sample Planting Plans

Plant species distribution and quantities have been selected in accordance with the Schuster Slope Landscape Management Plan and the existing site conditions as specified in the Management Unit 2 Work Plan. The following sample planting plans have been developed to illustrate the typical distribution and spacing of these plant communities on the site.

The Process

An extensive public process was conducted to inform the development of the management plan and to address concerns and desires of the adjacent property owners and the greater community. Three public meetings were held to discuss the progress and answer questions, and a citizen steering committee was formed to help guide the direction of the management plan.
