Project Status

First Hill Water System Improvements Project Substantially Complete—Three Months Early
June 25, 2012
 
In March 2012, contractor R.L. Alia Company began work on the third and final phase of the First Hill Water System Improvements Project. Work is now substantially complete on the $1.2 million capital project, three months earlier than projected.
 
This final phase was part of an extensive water infrastructure improvement effort for the First Hill neighborhood. The project began in 2009, when City replaced the water main and system components on 72nd Avenue SE. Then in 2011, we made improvements to the First Hill Booster Pump Station, located at 74th Avenue SE and SE 32nd Street.
 
Under the final phase of the project, the City replaced and upsized 3,520 lineal feet of water main and converted an additional 3,500 lineal feet of water main from a gravity system to the First Hill pumping system. We also replaced 140 water services and eight fire hydrants in the neighborhood, and made extensive property and pavement restoration and other related improvements.

The City of Mercer Island regularly evaluates our water system to ensure that the infrastructure remains in good condition and maintains adequate capacity to provide water to customers. The water mains in the First Hill neighborhood were undersized and aging. In several areas, fire flow capacity was below the minimum standard of 1,000 gallons per minute (gpm), as defined by the City’s Water System Plan, adopted by the Department of Health in 2008. This current work provided much-needed improvement to water supply and fire flow for houses in the area.
 
Over the past three months, First Hill neighborhood residents patiently withstood disruption to their water service and periodic road closures. We are grateful for their cooperation during this important work.
 
If you have questions about the First Hill Water System Improvements project, contact Rona Lin, P.E., City of Mercer Island Utilities Engineer, at (206) 275-7806 or rona.lin@mercergov.org.
 

Project Background

Neighborhood: First Hill

Exact Location: The boundaries for this project, outlined on the Vicinity map, lie between SE 29th Street and SE 36th Street, and between 71st Avenue SE and 74th Place SE.

Project Type: Water

Description: The First Hill Water System Improvements Project is a three-phase, extensive water infrastructure improvement effort for the neighborhood. In 2009, the City replaced the water main and system components on 72nd Avenue SE as part of the first phase. Then in 2011, we made improvements to the First Hill Booster Pump Station, located at 74th Avenue SE and SE 32nd Street.
 
The contractor for this final phase of work will:

  • Replace and upsize approximately 3,500 lineal feet of water main
  • Replace approximately 140 water services and seven fire hydrants
  • Construct 13 water main connections
  • Make property and pavement restoration and other related improvements
Project Timeline: Construction of the third and final phase of the First Hill Water System Improvements Project will begin in mid- to late March, 2012. Crews will work about 30 weeks, so we expect the project to be done by early October, 2012.

Estimated Budget (2009): This final phase of the First Hill Water System Improvements Project is estimated to cost $1.2 million. Total project cost will be approximately $2.5 million.

Project Status: To help keep area residents informed of our construction progress, we will post project updates to this site on a regular basis.
Impact to Residents: Area residents will be impacted by disruptions to your water supply and traffic delays. We will have a number of water main shutdowns; these will occur between 9:00 am and 5:00 pm. You could also experience intermittent shutdowns for replacement of your individual water service; these may have a shorter duration. The Water Service Replacement map identifies those parcels which are planned for new service.
 
You will experience traffic delays. We may have occasional road closures that require us to reroute traffic, but our contractor will try to keep at least one lane open on each road. Your landscaping may also be impacted when the contractor digs trenches to install a new service line, reconnect your new service, or relocate a meter.
 
The City of Mercer Island will send you a notification postcard regarding water main shutdowns the week prior to shutoff. We will hang a reminder notice on your front door the day before water shutdowns and street closures.
 
Important: Notify the City now if you have special landscape plants, irrigation lines or invisible fencing, particularly if they are located near the meter box. Also, keep everyone safe by keeping kids and pets away from the construction zones.
