Rubber Mulch Replacement – Status Update

Project planning and design considerations are underway. The project scope is broader than the removal of rubber mulch with the replacement of wood mulch.  The different materials have different drainage and depth requirements to maintain the same critical fall height.  Additionally, each playground is unique in its layout and design. Capital Planning hired a consultant in July 2017 to assist MPS in designing for this project.  This consultant, SAS Associates, was responsible for the design and construction administration of the removal and replacement of rubber mulch of the playgrounds for Duluth Public Schools. We have been working to evaluate different play scape materials, profiles, and ongoing maintenance costs. Poured in place, engineered wood fiber, artificial turf, and rubber tiles are all potential options.  The type of playscape material may vary depending on the characteristics of each site. Planning and design is currently underway. The table below provides the project length of a typical playground.  We anticipate staging of this schedule will be set so that construction begins during the 2018 summer break.

Table 2 below shows the current prioritization of playgrounds for construction.  The schedule will need to be flexible to accommodate changes as they arise.  Arson at Hmong International Academy and Cityview Schools has pushed these sites earlier to the design.  Additionally, several playgrounds will be part of larger capital improvement projects.  Initially we had hope to initiate Priority 1 projects in 2017.  However, as we began to uncover the complexity of this project the timeline has shifted to construction commencing in 2018.
