A team has been built that includes Portland Water Bureau (PWB) staff, Portland Parks Bureau staff, and representatives from both the Mt. Tabor Neighborhood Association (MTNA) and the Friends of Mt. Tabor Park (FMTP). This team is tasked with planning and oversight of the work called for in Resolution #37146.
In the spring of 2016, this team hired a local historic preservation consultant to update the 2009 Mt. Tabor Historic Structures Report (a.k.a. “2009 HSR”) with an analysis of current conditions and current construction cost estimates. Rob Dortignacq is the author of the original 2009 HSR, so his familiarity with the project allowed the update to move efficiently. The 2016 update that was produced allowed the joint PWB/community team to set realistic priorities for work to be done with the $4 million committed to by City Council.
In March of 2017, the historic-preservation contracting team at Akana was selected to help execute the preservation work and make sure that it is carried out with the sensitivity to the historic resources. Akana is a Native-American-owned, Northwest-based, professional services firm that helps clients plan, design, engineer, and manage projects in the built environment. Akana will be with the Historic Preservation Project for the duration, helping the joint PWB/community team efficiently bundle, contract for, and manage the many individual tasks that need doing on Tabor.
Construction activities to repair and rebuild the historic features of the reservoirs in Mt. Tabor Park began in November 2017. The areas impacted are the reservoir loop walkway around Reservoir 1, the concrete stairway on the dam face between Reservoirs 5 and 6, and the paved pathway around Reservoir 6.
Reservoir 1: Work around all but the south wall of the reservoir is complete, and the sidewalk around the reservoir will reopen to park users by the end of this week. Concrete work will continue on the south wall for several more weeks.
Reservoir 5: Concrete work on Gatehouse 5 is almost complete, and should be done by this Friday, June 29.
Reservoir 6: Concrete repairs will be made to both the east and west gatehouses at Reservoir 6 beginning early next week. To conduct this work, a large piece of construction equipment must be staged right next to each gatehouse. The equipment will block the sidewalk so park users will need to use the signed detours to walk around Reservoir 6. This work will take approximately 2-3 weeks.
Reservoir 6 was drained, cleaned and refilled in late spring. While it was empty, extensive concrete repair work was conducted on the basin and walls.
Reservoir 5 will be drained, cleaned and filled once weather conditions permit. Due to a dry spring, the Portland Water Bureau adjusted some scheduled maintenance work, including draining and refilling this 50-million-gallon reservoir. If projected weather conditions change, the Portland Water Bureau will assess whether rescheduling this work prior to the fall is a viable option. In the meantime, park users may notice that the water in Reservoir 5 will be a different color than the water in Reservoir 6, that recently underwent maintenance. The PWB is monitoring both water quality and levels this summer to inform its future Mt. Tabor Reservoir Management Plan.
Preservation construction activities on select historic reservoir and gatehouse features are scheduled for the next three years. Updates will be posted here.
