Log Cabin Reservoir Project

Project Description

Log Cabin Reservoir RenderingThe City does not have sufficient water storage capacity for Olympia’s east side, therefore we are constructing a new standpipe water tank (reservoir) that will be 140-feet tall and 80-feet wide, along with a 2,000 foot 16-inch diameter water pipeline.

The new water tank will provide water storage for fire protection and during emergencies or power outages. The water tank will provide adequate storage for the next 25 years. The photo on the right is an example of what the tank will look like.

Frequently Asked Questions

  • Planning for the project began over 10 years ago as part of the City’s 2004 Water System Plan.
  • There is an existing storage deficit of 1.2 million gallons of water that is needed for fire protection and storage during emergencies or power outages on Olympia’s east side.
  • The new reservoir will supplement the existing Hoffman Reservoir and support future potential growth for 20 years or more.
  • The existing Hoffman Reservoir needs to be taken off line for necessary maintenance. In order to do this, the new Log Cabin Road Reservoir must be constructed and put into service so there is adequate water and pressure to the area while the Hoffman Reservoir is not available.

  • The five-acre parcel was purchased by the City because it is the only undeveloped, high point in the area that meets water system needs and that can provide necessary water storage capacity on Olympia’s east side.

  • Approximately 2,000 foot 16-inch diameter water line will run from supply and distribution pipes in Morse-Merryman Road to the reservoir site.

  • The approximate dimensions of the tank will be 140 feet tall and 80 feet in diameter. It will look similar to the Hoffman Reservoir located at the end of Hoffman Court. 
  • The total reservoir capacity will be 5.2 million gallons.

  • The total budget is $12,600,000, which includes the purchase of the property, design, and construction of the water main and reservoir.
  • Existing and future City of Olympia Drinking Water Utility rates will repay a federal low-interest loan provided through the State of Washington Drinking Water Program. General facility charges, a one-time charge to new development, will also be applied to the loan.


  • Survey staking to mark the five-acre parcel and the 42-foot water line clearing limits.        
  • Trees marked for removal. NOTE: Please do not remove any survey stakes or flagged markers. This will result in additional project costs to re-do the work.
  • Construction of the water tank and water pipeline is scheduled from April 2017 to June 2018.

  • Implications of and impacts to adjacent neighbors and neighborhoods from construction activity.
  • Possible loss of some passive recreational opportunities on the Reservoir site (walking, running, and biking).
  • Some loss of environmental preservation (trees and habitat).
  • Increasing development and urbanization on Olympia’s east side.
